Affordable Computer Parts

September 2nd, 2010

Most of the time by looking at any price list from a PC store you can tell which are the most appropriate components to buy, in order to balance out price and performance. Sometimes you have to do a little research before you make the purchase.





When we talk about affordable computer parts logically all high-end components have to be ruled out. The reason for this is very simple, usually the components with the highest performance and/or capacity cost at least twice as much as similar components with 20-30% less performance and/or capacity.

Desktop processors are very fast these days. Intel is leading the industry in performance, but when it comes to efficiency, price and power consumption, then AMD takes the lead, although it wasn’t able to to make high-end processors yet. Right now the best Intel has to offer is the six-core Core i7, which of course is extremely overpriced at $1000, while AMD’s six-core solution is available at around $250, although in benchmarks it’s even slower than a quad-core Core i7. AMD’s Six-core Phenom II X6 1090T obtained 8293 points while the six-core Core i7 980X scored 11356 in benchmarks made by Tomshardware with PCMark Vantage. Bottom line, you give $750 only for a 30% performance increase, not to mention the fact that for the Core i7 you need a new LGA 1366 motherboard with X58 chipset while AMD’s Phenom II X6 works fine with many AM2+ motherboards with an updated BIOS (DDR2 also supported).

Hard drives follow a very similar rule. A 80GB hard drive costs around $36, 500GB – $54, 1TB – $70, 1.5TB – $90 and 2TB – $110. While the 80GB hard drive seems to be amongst the most affordable computer parts, it’s basically throwing out money, because for an extra $18 you get 6 times the capacity (and higher speed too). As for the price/GB indicator, the smallest (80GB) drive offers 1GB for 45cents, the 500GB one for 11cents, 1TB – 7cents, 1.5TB – 6cents, 2TB – 5cents. This clearly demonstrates that 1TB drives are the most affordable. Because 1TB, 1.5TB and 2TB drives have very similar cost/GB we can conclude that the industry is preparing to launch bigger hard drive very soon, as a matter of fact Seagate has already launched an external 3TB hard drive that’s based on only one unit, although this may be a little taller than normal physically and still needs to be improved.

Motherboards are less important in affordable computer configurations, because if you don’t want to push the limit then any cheap model will do (try to buy something at least 20% more expensive than the cheapest model).

There are two video cards out there that are absolutely worth buying, one of them is also affordable. The Radeon 4650 equipped with 1GB of DDR2 memory is a budget solution for multimedia and casual gaming at decent framerates. It has a $50 price tag.

The other one comes also from ATI (AMD), the Radeon 5750 with 1GB GDDR5 offers exceptional performance at a fair price, only $124. It obtained 358 points in a Tomshardware benchmark, while the single-GPU leader, the Radeon 5870 scored 718 points, but costs more than $360, three times as much as the 5750.

As I recently discovered high-end memory modules aren’t really a necessity. Even high-end computer systems show little performance difference between 6 pieces of individual (but identical) modules and two identical 3-module high performance kits. Please note that simple individual modules don’t offer any real overclocking.

Computer adaptors

September 2nd, 2010

Check the connections to the computer before buying
When buying a new computer, check that it is well equipped for connections . Otherwise you will need to purchase an expansion card or an adapter cable and which will increase your bill.





Choice of connectors
When purchasing computer hardware (computer, motherboard, expansion card), you should always choose the ones equipped with the latest connectivity.

The technologies will be most successful, faster, often simpler to use and that can certainly be used longer.For more mobility, choose the common connectivity go for the most common connectors if you need mobility.

For example, an external hard drive, USB2 connectivity lets you use it on any computer while the FireWire and, especially, eSATA, although faster, are much less common

For more connectors
To provide management connectors lately, old or uncommon, many adapters and controller cards are available.

Monitor Connection
The VGA connector is a great connector for CRT. If you wish to use a flat screen, it is better to be oriented towards the DVI or HDMI.

Prefer USB
To operate your devices simultaneously you should have one provided with USB connectivity. Indeed, computers are always equipped with a large number of USB plug. In addition, USB hubs can increase the number of ports supported.
USB hubs
get USB hubs with external power supply separately. Problems often occur on those devices because of a power failure.

Playing protected videos
If you want to play protected video by HDCP BluRay or HD DVD, the entire distribution (screen, video card and reader) must support this protection protocol.

Wireless Connectors
Infrared
Transmission at short sight or by reflection of infrared light for transmission from 1to 2 Mbit / s.

Bluetooth
The Bluetooth as Wi-Fi uses radio waves to transmit data. However, he accepts a much lower debit and a radius of action . It is used for keyboards and mice upscale, but also for transfers from mobile phones, PDAs, GPS …

Wi-Fi
Wi-Fi is the wireless version of network connections (RJ45). Mainly used in ADSL modems to deliver Internet in all rooms of a house for example . The radio wave transmission enables distances of 30 meters indoors and 100 outdoors at speeds of 12 Mbps 802.11g and 54 Mbps 802.11g. Future releases 802.11n will increase the distances and speeds. After the modems and routers, the printers started being equipped with Wi-Fi .

UWB
This is the wireless version of USB for connecting external devices. The scope should be 10 meters for a flow rate of 1 Gbit / s.

WHDMI : Wireless HDMI
The WHDMI is the wireless version of HDMI. It should be capable of reproducing a video stream with a resolution from 480i to 1080p, all on a distance of 7.5 meters.

Standards and certifications are being established.
Feel free to use the wireless versions of connectors, protocols are now very mature and work perfectly with it . Improving design and usability, by decreasing the number of unsightly cables while increasing the range and possibilities of availability .

Adapters
The adapters are numerous and very useful. Be careful, however, the functions they can support rarely preserve all port properties they convert.

Mouse and keyboard

September 2nd, 2010

What is an ergonomic mouse? It may be a truism, but, first, remember that the mouse does nothing a frivolous accessory does  . It can be a source of fatigue, discomfort to your hand. As such, look for where its ergonomics, which must be as careful as possible to guarantee good comfort in adapting to your hand.





Ways of using the mouse
Two categories: first, the peaceful uses (office, web, graphics, etc..), On the other hand, intense uses (mostly games, particularly those of action). Depending on your dominant use category, you’ll have interest to prefer a mouse for comfort, efficiency or otherwise.

In search of efficiency
If it’s efficiency that interests you, choose a mouse easy to manipulate . Once again, depending on your taste in grasping and the morphology of your hand, opt for an alternate mouse small or otherwise bigger, but its shape allows you to squeeze it easily. You can easily control a small mouse with your fingertips.

General notions of performance
If your use of your mouse requires great precision and responsiveness, whether you plan to play aggressively, want to do graphics or more generally to attach great importance when you are interested about the quality of the optical sensor board. High range models are recomanded when needed, even if it is possible to find exceptions in the lower ranges.

Farewell ball and hello sensor
The mice in the previous decade were still equipped nearly all with balls. The third millennium marks the end of this archaic mode and give up for optical sensors. Lose once and for all the ball . You are interested in the quality of the optical sensor supplied with your mouse. In any event, unless you have a use particularly demanding in terms of accuracy, any current optical sensor should satisfy you. If you can,  laser sensors are less sensitive to the quality of the surface on which they operate.

We think of Mac users
Besides multimedia buttons, some keyboards also offer a wide compatibility with Mac OS X through a number of special keys come straight from the keyboards of Apple computers. Mac users are interested into their presence.

Autonomy use
The autonomy of the mouse, namely the maximum period during which it can operate without its batteries have to be recharged, or  replaced. Count one to several weeks up to months of life in common use for different types of batteries .

Disappearance of wire and maximum range
For wireless mouse there are two other features. The first is the scope of the mouse, which determines the maximum distance between the mouse and its receiver to ensure its functioning. Be very careful about it if you intend to use your computer from a distance (from the bottom of your sofa or your bed for example!).

Wireless power feeding keyboards
The autonomy of these wireless keyboards, knowing that its poweroccurs in the vast majority of cases by conventional batteries, and whose life exceeds ten months.

Choose you desktop computer

September 2nd, 2010

A computer already assembled is a perfectly valid choice if you do not want to break your head or if one does not have basic computer skills. But for about the same price, it is possible to obtain a machine more suited to your needs if you bother to assemble it yourself .





Price / performance
The price difference is often minimal between low end and midrange computers . Unless you have a tight budget, it is wise to opt for a computer “middle range” because in this range are found the best price / performance. The entry-level computers often use less powerfull  microprocessors (with less internal cache for example).

Using Office
For office use, virtually any desktop computer would work and this is the case, regardless of the operating system: Windows XP, GNU / Linux, Mac OS X. .. The current performance levels are such that the computer’s lowest range is able to manage any task from word processing, spreadsheet manipulation or browser. In these cases, a normal integrated graphics card to the motherboard is not something disadvantageous because the display needs are low.

PC Home Cinema
For  intensive multimedia use  (Home Theater for example ) or for high-end gaming, you nurture the audio portion of the machine. All current motherboards have integrated sound chipset fully able to meet the normal requirements (at least the standard AC97). If you want an integrated chipset higher quality, choose the HD Audio, newest and that supports Dolby Pro Logic IIx for 7.1 channels. Another possibility is adding a separate audio expansion card, more powerful, like the Creative Audigy or X-Fi or M-Audio Revolution 5.1 or 7.1.

Gamers
If you are often playing games using advanced graphics and animations (especially any recent 3D games), it is recommended to avoid solutions of PC with an integrated graphics card, they are much less efficient than separate graphics cards. Or, go for a PC with at least one port PCI Express X16 (port dedicated to graphics card) allowing you to add a discrete graphics card later.

Mac or PC?
If the games are what interest you first, preferably go for a PC. Indeed, regarding games , PCs performance are far superior than that of the Mac. In addition, the amount of games available on PC is much more important. For arts and crafts, the mac often prevails among artists. Finally , the PC remains the best option because the software is more numerous.

Windows Vista or 7
If you intend to use Windows Vista or 7 on your new machine, be aware that this is an operating system using graphics intensively. It must therefore provide a machine with a separate high-performance graphics card (designed to work with Vista Aero Glass interface and DirectX 9) and avoid the   integrated graphics on the motherboard.

Pack Software
The software package provided often includes other programs such as Microsoft Office suite or antivirus utilities and miscellaneous. And sometimes , with an Internet connection, you can download free software for a quality equivalent to that of commercial products (obviously for GNU / Linux, but also for Windows and to a lesser extent for the iMac). For example, OpenOffice, AbiWord word processor or ClamAV antivirus (Clamwin for Windows).

Website and internet support from manufacturer
Check the quality of Internet services offered by the manufacturer of your machine and its main components  (operating system, motherboard, graphics card, disk (s) drive (s), scanners …). It should be possible to get help easily, by several means, whether through the FAQs (Frequently Asked Questions), discussion forums, via email, etc.. Note that there are often special utilities not necessarily provided on the original installation CD (for example test programs / formatting / repair hard drive …).

5 Laptop parts

September 2nd, 2010

Screen
There are different screen sizes today, each corresponding to different resolutions. It is an essential feature of the laptop for example because it determines its size and weight. There are eight main types of screen (the letter W in head marks the presence of a screen of the size 16/10).





The main types of screen:
- XGA: maximum resolution of 1024×768. These panels usually equip low-end PCs or those with small screen.
- WXGA: maximum resolution of 1280×800. These are widescreen 15 “4 in general. A preferred if you intend to watch many DVDs, the format is the 16/10. Avoid if you want to play or use it in the office.

- SXGA: maximum resolution of 1280×1024. For screens under 15 “.

- SXGA +: maximum resolution of 1400×1050. Suitable for all types of use, it is certainly the most versatile of the slabs.

- WXGA +: maximum resolution of 1440×900. This is the highest resolution used on the main diagonal.

- WSXGA +: maximum resolution of 1680×1050. These are the best slabs, but also more expensive.

- UXGA: maximum resolution of 1600×1200. Excellent for all types of application.

- WUXGA: maximum resolution of 1920×1200. Here, the laptop`s monitor set a high standard resolution .

The display technologies are almost all similar. Only the surface treatment of the slab (anti-reflective, glossy, etc..) And lighting technologies (tube or diode) varies. The laptops screens remain highly variable in quality, although some parameters differ. Only a test can visually get an idea just before the purchase.

Graphics card
The graphics card is the component that displays images on the screen and, in some cases, to apply 3D effects. It can be built into the chipset (Intel Extreme Graphics, Intel GMA 900 / 950, or M650 SiS740, ATI Mobility Radeon 9100 IGP), which displays the cost and the motivated autonomous higher because of low energy that it consumes. In return, the performance is often lower than those of discrete graphics cards from NVIDIA or ATI, which have the possibility to have a dedicated graphics memory.

The hard disk storage
This is where your documents and the files on the computer are stored. The laptops hard drives are specific: they measure 2 “wide by 5 (instead of 3″ 5) and are less efficient than those of desktops.

Among its features, speed is a fairly reliable indicator of performance (note the increasing consumption). The capacity is expressed in gigabytes as their counterparts dedicated to desktop computers.

Today, a minimum of 40 GB is required for normal use. As for speed, it must be of 5400 rpm to provide a satisfactory level of performance. Some hard drives for laptops operate at 7200 rpm, but they remain a minority and relatively expensive. When buying, do not give importance to the communication interface used. The difference between serial ATA and IDE is not felt.

The sound card
The sound card is used to ensure the processing and dissemination of all the sounds produced by a laptop. It is the only parameter that does not really matter: the sound of a laptop will never be exceptional because the speakers are embedded in good quality. Make sure that a headphone jack is present, this is important if you do not want to disturb people around you.

Writer / optical drive
All laptops are now equipped with at least one handset player-recorder, that is to say CD or DVD that can also burn CDs / DVDs. Finally , make sure the drive is well dual (it is almost always the case), that is to say it can burn DVD + R, DVD + RW, DVD-R and DVD- RW.

Choose you graphic card

September 2nd, 2010

The graphics card has any real importance in the fields of 3D applications. For the Internet, watching classic video (not HD) and office, almost all graphics cards market is sufficient. There are many types of graphic cards depending on the need an dthe price you are willing to give for it .





It is always difficult to find a graphics card with a good price quality relationship . There are also graphic cards that   know how to correctly operate video games, even if they are  not  in their best quality. They must also be versatile and can provide an opening to a digital video. In the world of video games, nothing is too powerful to run your favorite titles more than a gamer graphic card . The compromise on the power should not be too important, but one should still seek to find the best power / price.

1. Choose the card for your needs
The graphics card has a real importance in the fields of 3D applications. For the Internet, watching classic video (not HD) and office work, almost all graphics cards found available on the market are sufficient.

2. A signifucant power feeding for a powerful card
Graphics cards mid / high range often require an additional power supply. It is therefore advisable to have a PC power supply powerful enough and have a free connector to run the card.

3. Multifunction cards
Some say multifunction graphics cards offer, in addition to display features a TV tuner and video capture functions. They are good products to bring diversity in the use of your computer even if their performances are still inferior to specialized products.

4. Cards suitable for video editing
For video editing, orient yourself towards dedicated solutions that actually accelerate the design of sequences. The graphics are not adapted to this type of work and discharged entirely on the processor of the computer: the contribution is zero.

5. The card with HD resolution
To watch HD videos, go for a dedicated graphics card, the integrated circuits are generally too inefficient to properly provide high definition.

6. Little interest in the upscale
The models most high-end home builders are often more a technological showcase than real bargains. Check rather the middle-high range that offers the best cocktail systematically performance, power and price.

7. Choose the PCI-Express
In the case of buying a graphics card for a recent computer (less than 2 years), the connection standard PCI-Express is the most common.

8. 512 MB, or nothing!
512 MB of RAM is usually sufficient for recreational classic use . In addition, the gain is significant that in the case of using very high resolution.

9. Cooling system for your comfort
Be sure to opt for models of graphics cards featuring an impressive cooling system, it is often the quietest.

Flat LCD screens

September 1st, 2010

1. The choice of digital LCD is a must!
The flat digital LCD have one or two DVI ports (white port). If we make a choice, it is to these models we need to turn now . The advantages are many: image quality, signal in full digital, easy settings.





2. The choice of sizes to avoid eyestrain
For an entry level for casual users , they will appreciate screens 19-22 inches .The average size of the screen to a regular user hovers between 22 and 24 inches, it seems best to avoid eye strain. Movies fans users can go up to 36 inches

3. The 16 / 9 and nothing else
The format 4 / 3 is totally obsolete. Emphasize 16 / 9, very generalized format on the market today. These screens are widescreen quite adapted for movies or for games.

4. The inclination of the screen for a good sitting position
The leveling of the screen (5 degrees downward and 20 ° at the top) does not move and it is better if you can, to a model with, in addition to setting the angle of rotation (350 °) and the adjustment of the foot in height , these models will guarantee an ideal sitting position (position of eyes and neck)to visual comfort

5. Prefer buttons settings frontal
For convenience, choose the Settings button front rather than side. Indeed, it is still very cumbersome to make adjustments in groping for the appropriate buttons on the side of the screen.

6. Avoid the tip with an external power supply
The integrated power monitors in the basement or in the monitor are increasingly common. It is wiser to choose a model with external power, because in case of failure or end of warranty, the transformer will be easy to change.

7. Switching from one source to another via the remote
The remote is not a gadget, allowing not only to switch from a source (TV / monitor …) to another but also to make adjustments in brightness at a distance, very practical, when we look at a video from distance .

8. Defective pixels, you need to know
Read the warranty conditions, particularly those related to the change of the screen where the pixels are defective (white dot on the screen). According to ISO 13406-2, most manufacturers must change the screen when a pixel (3 sub-pixels) or 5 sub-pixels do not work. In fact, this is very variable.

9. Each family of slab has its own use!
The TN is  not well suited to uses requiring an excellent colorimetry and the viewing of movies because it is thriving as the XVA. The SPI is less suitable for games (unlike the TN + film) because its reactivity is generally less good, although there are some exceptions.

Compare Laptop Computers

September 1st, 2010

There are two types of computers : Macintosh and PC





The question remains, more than ever, given the quality and success of Apple machines (Macintosh or “Mac”) in recent years. It must first be remembered that these two types of machines that do not use the same operating system. Windows is present in overwhelming majority on notebook PCs, while Mac OS X is the exclusive system of Mac. If the material that makes up modern Macs is very close to what is on a PC in architecture as in the nature of components, the operating system maintains a difference between them . The software, when they exist on both platforms are different, but the main files generated by these two types of machines are compatible: for example, a Word file created on Windows can be read and edited in Mac OS X. And vice versa .

The choice between Mac and PC depend mainly on its use , and the relative importance that is given to certain parameters. The ease of use and design are on the side of Mac. In return, the number and variety of software available for Mac are reduced even if the applications are most common and most useful available and meet the standards of compatibility with PCs.

As for the PC, you can count on the diversity and abundance of available software, but also a greater power, especially for very intensive use, and video games. Note also that the additional device compatibility is always guaranteed, which is not the case with Macs.

Centrino labels : sure for mobility
The labels used on laptops meet the need of unity created by the multitude of components available on the market. They appoint, with specific names, packages that are consistent in recognizing the first glance the heart of the technological content of a machine.

They are essential on portable machines. Those that occur most often are the Centrino and the Centrino Duo. These specific designations chipmaker Intel. They are used to recognize sets of chipsets specially dedicated to mobility. This is one trend that is spreading the concept attracted both OEMs and consumers: for proof, labels Intel Viiv or AMD Live! which, in their respective fields, are slowly emerging.

The economic models of computers and multifunction
Economic models can fully meet basic needs. Office, Internet browsing, e-mail or play music and videos are skills that this type of machine has. They represent a large share of sales of laptops and are the cause of democratization in this market. These are mainly machines with screen 15 “or 15″ 4. The inside is often composed of an entry-level processor and a memory whose size is reduced to a minimum, as storage space offered by the hard disk.

The multifunction models of laptops are good to do everything and, as such, their homogeneity and characterized. The processor king in this category is the Dual Core 2  because it is powerful, flexible and low fuel consumption in battery. The couple screen 15 “4 (size 16/10) + DVD is a must for viewing videos. And not to be tightly packed, 60 GB hard drive will be necessary. Of course, the presence of a chip ATI or NVIDIA would be a plus for the casual gamer.

The fun laptop and ultra-laptops : Laptops fun oriented  to replace a desktop machine is a marked improvement in power, but they often pay a reduced autonomy. While the Dual Core is a reference, it has serious competitors, including our newest: the Dual Core 2 . The key lies however in the circuit graph must necessarily possess its own memory to be powerful enough. In this area, ATI and NVIDIA have the best offer.

The ultra-portable computers are the showcase for manufacturers. They are true marvels of technology. In the first place , the criteria for independence, compactness and design become paramount.

A laptop comparison

September 1st, 2010

1. Best laptopsIn recent years, the laptop is becoming more important in the field of computing. Now, for the first time, its sales have surpassed those of desktop computers in the United States. Between netbook and notebook, the choice remains to be done.





Here is a comparison of computers :
2. All-in-One, Ultra, or design, your PC at the right format!
It is important to target the size of the laptop based on the use you make of it. This goes along with the size of the screen. Do not be tempted by a big screen if you plan to travel regularly.

3. Beware of the weight
If you intend to travel regularly, pay attention to the weight of your machine. Above 2 kg, the computer is less mobile because, added the weight of accessories, the bag and many other items that will quickly make it hard to move with .

4. The autonomy, essential for the mobility
Autonomy is a very important criterion. In fact, if you plan to use your computer anywhere, it must have a good autonomy. Several parameters are taken into account. The screen first: the larger it is, the more it consumes energy, and the computer is less durable. It’s the same for the graphics card. When integrated, the autonomy of the system is improved. However, if a dedicated graphics card, it may consume a lot .

For the processor, it depends on the heat it releases, otherwise known as TDP. Over this data, the lower it consumes. Batteries: the more they contain “cells”, the more they allow a good autonomy. Finally, choose the right compromise between the number of cells, the price of the machine, its components and its weight.

5. Hard disk: capacity and performance
Beware, it’s not just the ability that matters! If 80 GB is now a minimum for an acceptable comfort, hard drive running at 4200 rpm is too slow to provide decent benefits and has virtually disappeared. Currently, the standard is around 5400 rpm (make-in). The disks for laptops 7200 rpm represent the high end and provide for the use, approval and additional significant. Some manufacturers also add functions to protect data against accidental bumps . In 2009, we must also take account of the democratization of the DSS, this format storage device based on flash memory. Still expensive, this system offers improved performance in access time, reading and writing.

6. What processor for common use?
Today, all processors in the market are sufficient for common tasks such as office, internet surfing, watching movies, MP3 files or photos. The difference between a high-end machine and a machine input range is mainly due to comfort (responsiveness and multitasking) and the autonomy of the service.

7. What processor for advanced use?
The games, but also video editing, HD playback or 3D graphics require powerful processors. In the field, the Intel Core 2 Duo is now a must because of the strength of its two cores combined with autonomy authorized by the intelligent management of consumption. The latest Intel Centrino 2 platform will be on a plus in this case.

8. A quality keyboard for comfort
It is impossible to replace a keyboard on a laptop, so be sure before buying it that the keyboard has a good quality, the keys are well laid out and the touch is enjoyable. Likewise, the touchpad should be balanced, and sensitive keys click as failing rapidly transforming the everyday into a nightmare. Only tests on products can give you an idea.

9. How much memory (RAM) is needed?
It takes at least 2 GB of RAM for use with Vista basic or intensive (several programs running at the same time) with XP. For games or for more comfort and responsiveness, it will also have 2 GB in Windows XP . Recall that under Windows, only a 64-bit OS handle more than 3GB of RAM.

Dedicated or integrated graphics cards ?As part of a standard use, all the chips on the market agree. For  gamers and graphic designers to manipulate 3D objects, the presence of a  dedicated graphics chip, with its own video memory (256 MB of RAM) is a  virtual requirement.

Computer Parts And Components Explanation

September 1st, 2010

Definition of a computer:
It is a machine that can store data (information) and structured the deal to the user’s request to produce a desired result. The computer is a tool that automates the operations of any kind in order to facilitate the work, therefore people’s lives.





A computer does nothink about your place: it only assists you and suggests solutions. A computer does nothing without order or by itself: it needs software and orders to operate.  The essential parts of the PC: The tower is the foundation (the heart) of the computer-: thanks to the components that are inside, your orders are interpreted (translated into its language), analyzed (organized), processed and the result is sent to you.  The keyboard is the link (the means of communication) between the user and the computer.The screen is used to represent the image of the result of what you ordered.  The motherboard is the component of the computer that manages and organizes the functioning of all other components and gives the orders, data from the outside.

Indeed, it is the prime contractor for the processor and everything else, so that the process of analysis and response to function properly. Note that the keyboard and mouse are directly connected to the motherboard that redirects the information to the relevant components (CPU, graphics card, sound card …). Different ports on the motherboard:  Ports are the locations of components that are connected to the motherboard.  Ports ISA connectors are used less and will disappear. This is explained by the low speed data transmission.

Ports PCI connectors are widely used by some video cards, sound card, network card, 3D card … This is explained by the good speed of data transmission.  Serial ports (total 2): also called Com1 and Com2, are most often used to connect some mice, modems … USB Port: The port of the future. In this sense it offers exceptional speed and you can connect up to 127 devices in series on each of them.

Processor:  The processor is the component that calculates, processes and interprets information, data sent by the motherboard (after orders from the user).  He treats the interpreter and retransforms so that we can use (in the form of images: dialog boxes, windows …), always through the motherboard. There are basically (for individuals) 2 brands of processors: Intel and AMD.  The two brands of processors:

Mark “Intel” and with PENTIUM CELERON
Brand “AMD” with two K6, K6 and Athlon 3. Every six months, a new processor comes on the market due to very fierce competition between these two brands and consumer applications requiring still more power. The graphics card or video card: This is the component that handles all information regarding the display and sends the result on the screen through an analog signal. This component is crucial in terms of speed and quality of the display (color depth, resolution ….).
