A CPU (which is also known as a central processing Unit) is basically the part of the computer of where most of the processing of calculations takes place. some people refer to it as the “brains” of the computer. Processors are used in all types of computers
The CPU plugs into something known as a CPU socket which is located on the mother and this socket delivers electrical contact to the microprocessor and to something known as a printed circuit board. In the case of chips with have a big number of pins land grid array sockets or zero insertion force sockets are used as a alternative.
CPU speeds are measured in hertz or in giga hertz. Clock speed is basically the measure of how many clock cycles a CPU can do in one second.

One usb port can be used to connect up to 131 devices such as mice, keyboards, Phones and memory sticks and even printers. There are three different types of USB’s such as USB 1.1, 2.0 and 3.0.
Parallel port
A parallel port is a port that supports external devices such as printers and monitors and keyboards etc. A parallel port uses a 25 pin connector. In 1994 a new type of parallel port was introduced which is known as the enhanced parallel port EPP for short. And then the next one is called an extended capabilities port (ECP) for short. The enhanced parallel port is faster than the older parallel ports because it supports transfer speeds of about 500 KBps up to2 MBps. This port is basically used for Later versions of printers and scanners.
Serial Port
A Serial Port is a type of port that also supports external and peripheral devices such as Mice, Keyboards, and Printers etc. Again this port uses a 25 pin connector. The downside to this port is that it can only transfer one bit of data at one time whereas parallel ports can transfer several bits of data at a single time. …show more content…
These “holes” connect through a group of electrical paths to the processor.
ROM
Rom which is also short for (Read only Memory) is a type of computer memory that stores data forever and is what a computer uses when it boots up. When data is put onto a rom chip it cannot be deleted because it is read only. There are a many of rom chips on the motherboard which are impetrative for booting up the system and writing and reading to other devices. There are four Other types of read only memory which are known as (Prom) (EPROM (EEPROM) (EAROM).
Cache
Cache is something that temporarily stores data that has been recently used on a computer so that it can be accessed immediately. Most Internet browsers use cache by default use. Internet browsers may use cache things for HTML images or javascript files. It does this because if the user wanted to go back to the same website instead re downloading all the files again to use that website it will just quickly load the files from the cache. There are three other types of cache Hard drive cache Ram cache and processor cache and each of them are used for different purposes. For example processors may want to use cache data so the it can be accessed quickly by the cpu. Most of the time cache is ran in the background so it when it is being used its not even
