Sony Computer Accessories

Sony Corporation is one of the planet’s biggest multinational conglomerates. With a $78 billion revenue and headquarters in Japan, Sony is one of the biggest manufacturers of electronics and IT&C products.

Three types of personal computers are made by Sony: desktops, laptops and all-in-ones (computer built into the monitor).

Sony computer accessories target mainly the portable segment with laptop carrying cases, docking stations, external VAIO drives, speakers, headphones, external hard drives, notebook locks and more. Sony (much like Apple and Dell) is all about looks. It has some very simple and yet elegant laptop case designs on the official website:

As you can see it doesn’t have anything extra that would ruin the exterior, there’s just one big compartment for a laptop with screen up to 11.1” (Sony VAIO X and V series, or other manufacturer’s models) and a smaller one for the charger, mouse, headphones and whatever you need. The $30 price seems fair, other manufacturers sell their similar products in the same price range. The VAIO P series lifestyle PC has a very unique 8” screen with a 1600 x 768 resolution:

Figuring that it won’t fit well in anything else, Sony is offering 4 different carrying case designs for this little laptop.

Asking prices are $40, $90, $90, $90 and $40 for the last model. For bigger laptops Sony came up with a very complex product list, for every taste:

This is just a few of them, but there are many more at reasonable prices. Interestingly enough there’s only one type of wired (non-wireless) mouse on the Sony website with a $30 price tag; it comes in pink, brown or white color:

Fortunately there are 8 different wireless and Bluetooh mice available for PCs and PS3 too:

This is a very unique mouse design, created especially for PS3, but it works with any Bluetooth capable laptop and desktop. Sony tried to make something very practical, a mouse which protects itself:

The interchangeable cover slides on the wheel and buttons to to protect them, but also to turn off wireless transmissions so the battery isn’t drained when you don’t use it. This may be the most irrational Sony computer accessory. These are portable speakers, but one would be tempted to use them with desktops too:

They come with an external power adapter, but there’s also a triple-A battery slot in one of the speakers so you can take them on the road, although it’s unlikely that maximum power will still reach 2 x 2.5Watt as with the AC adapter. For only $70 you can protect you privacy in public areas with the Sony brand privacy filter:

It’s available for Y and S series, but there are others compatible with Z series too, at the same price.

Basic Computer Hardware

Computer hardware is the physical part of the computer including the digital circuits inside the computer as opposed to the software that carry out the computing instructions. The hardware of a computer is unlikely to change frequently unless due to the crash or for upgrading them. The devices that is capable of storing, executing system instructions and controlling other logical outputs.

Hardware comprises all of the physical part of the computer such as Monitor, CPU, motherboard, ram, CD-Rom, printer, scanner, hard disk, flash drive (AKA pen drive), processor, pci buses, floppy disk, power supply, VGA card, sound card, network interface card, peripherals, joystick, mouse, keyboard, foot pedal, computer fan, camera, headset and others.

CPU (Central Processing Unit): CPU or central processing unit relates to a specific or processor. The performance of the computer is determined by the CPU chip (processor speed) and the other computer circuitry.

Hard Disk Drives – Disk drive is the mechanism to run the disks. All disks need a drive to get the information, read it and put it back to the disks. Hard disk is used to store the data permanently. Often the terms disk and drive used to describe the same thing but it should be clear that a disk is a storage device.

Modem – A modem is used for the modulation and demodulation of the data that is transferred through the modem and the telephone lines. Modem translates the data from digital to analog from analog to digital. Because on the telephone lines data can travel in the form of the analog signals and in the computer data transmits in the form of digital signals. Modems are measured by the speed which is called baud rate.

Video cards-Video cards allow computer to display video, graphics and animation. Some video cards allow computers to display television. A video card with a digital video camera allows users to produce live video. A high speed broadband internet connection is required to watch the videos on net.

Network cards: Network interface cards allow PCs to connect with each other and communicate. Every network computer is required to have a NIC card. NIC cards are required both in wired and wireless networking.

RAM (Random Access Memory) RAM is a memory that is being used by the computer to store the information temporarily. For example when some work is performed on some applications that work is temporarily stored in the RAM. More RAM in the computer more faster computer works.

Cards – Cards are the hardware components that are added to the computer to increase their functionalities and capabilities.

Memory – Memory is the one of the important piece of the hardware. Sometimes memory chip memory is confused with the hard disk memory. Sometimes unallocated space of the hard disk is used as virtual memory also known as page file. This type of memory is a temporary memory and is used actual memory is less and requires some additional memory to perform a specific task.

Computer And Its Parts

If you use a desktop computer, you might already know that there isn’t any single part called the “computer.” A computer is really a system of many parts working together. The physical parts, which you can see and touch, are collectively called hardware. Software, on the other hand, refers to the instructions, or programs, that tell the hardware what to do.

The illustration above shows the most common hardware in a desktop computer system. Your system may look a little different, but it probably has most of these parts. A laptop computer has similar parts but combines them into a single notebook-sized package.

The system unit is the core of a computer system. Usually it’s a rectangular box placed on or underneath your desk. Inside this box are many electronic components that process information. The most important of these components is the central processing unit (CPU), or microprocessor, which acts as the “brain” of your computer. Another component is random access memory (RAM), which temporarily stores information that the CPU uses while the computer is on. The information stored in RAM is erased when the computer is turned off.

A mouse is a small device used to point to and select items on your computer screen. Although mice come in many shapes, the typical mouse does look a bit like an actual mouse. It’s small, oblong, and connected to the system unit by a long wire that resembles a tail. Some newer mice are wireless. A mouse usually has two buttons: a primary button (usually the left button) and a secondary button. Many mice also have a wheel between the two buttons, which allows you to scroll smoothly through screens of information.

A keyboard is used mainly for typing text into your computer. Like the keyboard on a typewriter, it has keys for letters and numbers, but it also has special keys. The function keys, found on the top row, perform different functions depending on where they are used. The numeric keypad, located on the right side of most keyboards, allows you to enter numbers quickly. The navigation keys, such as the arrow keys, allow you to move your position within a document or webpage.

A monitor displays information in visual form, using text and graphics. The portion of the monitor that displays the information is called the screen. Like a television screen, a computer screen can show still or moving pictures.

There are two basic types of monitors: CRT (cathode ray tube) monitors and LCD (liquid crystal display) monitors. Both types produce sharp images, but LCD monitors have the advantage of being much thinner and lighter. CRT monitors, however, are generally more affordable.

Speakers are used to play sound. They may be built into the system unit or connected with cables. Speakers allow you to listen to music and hear sound effects from your computer.
