Name The Parts Of A Computer
The Central Processing Unit (CPU) is a component which determines the speed of the computer. This speed is measured in Gigahertz (GHz). The producers are offering different types of processors at different prices. The mother board is the nerve center of the computer and it coordinates numerous hardware functions. These contain chips, boards and cables for the installed components. Each personal computer has a power source which changes the alternative current into direct current. Another important component is the cooling fan. This prevents the overheating of the system. Usually this is attached to the power source.
The Memory. The ROM (Read Only Memory) chips contain instructions which are sent to the computer in order to learn how to communicate with the user and other hardware components. These are found on the mother board. The RAM (Random Access Memory) chips allow the functioning and saving of temporary files, as long as the computer is working. The capacity of the RAM chips are measured in megabytes (MB, 1 million bytes) and in gigabytes (GB 1,073,741,824 bytes). These chips are found from 128 MB up to 2 GB each.
The components which are chosen by the user. The personal computers have graphics cards, sound cards and other, which control the functions of the screen, speakers and secondary devices like scanners and printers. All the computers are using USB entries. The personal computers also need a network card or a modem in order to connect to the internet and other computers.
Entry and storage components. The keyboards and the mice are the most often met entry components used at a personal computer. It allows the user to send commands to the computer by typing texts or selecting options. The hard drive is the main storage unit for programs and files. Before the personal computers ever have these kinds of components, there were used disks for saving files.
The hard drives are simplifying the computer use and are making them more useful but not essential. A personal computer needs a CD or DVD drive for installing programs or copying files from the computer’s hard drive. Many manufacturers are building personal computers with a CD drive but without a floppy drive, but this can be bought.
Display. The computer’s screen allows the user to view the computer’s content. Today, the screens can show both text and graphics. Are able to display millions of colors. The personal computer’s screen needs a cable to be attached with, unlike the laptops which have the screen integrated in the computer.
Cases. The computer’s components must be put inside a case in order to protect the system from dust, water or any other danger. The personal computers are found in different models from the ones which stand vertically, to the compact ones which have built-in keyboards or screen.

[...] that could not have been foreseen a few decades ago when IBM rolled out the popular 8088XT based personal computers, most computer parts are 100% compatible, but also very different, even if we’re talking about [...]
i always prefer to use brushless cooling fans because they last longer and needs less maintennance~~:
