EPROM

This is a memory chip whose contenst are normaly fixed. However the chip may have its contens erased by the action of ultra violet light and may then be programmed.

Disk Cach

Disk cache is a pation of a computer's RAM set aside for temporarily holding information read from disk. It holds information that either has recently been requested from disk or has precariously been written to disk.

Cache Memory

Cache is an area of memory that held frequently acceded data or instructions for the purpose of spending a computer  system performance.

Memory Main Store

There are two types of memory.
  • ROM - (Read Only Memory)
  • RAM - (Random Access Memory)
Memory is the name given to a group of chips inside the processing unit. Here data is held temporaritly whilst processing takes place.

Storage of data

The number of instructions and amount of data a computer can sore in its memory is measured in bytes. A single character can be stored in one byte.

Branch Prediction Unit


This is a very special part of the processor. It inspects the nature of the instructions in the instruction cache and decides which of arithmetic logic unit is best suited do.

Arithmetic Logic Unit (ALU)

This unit forms the core of the processors and it is the section that performs are actual mathematical processing on the data.

Cache

After information is received by the BIU and the instructions are separated from the data, they are sent a small temporary storage region knows as cache. The data and instructions stay in the cache unit any other part of the processor needs it.

Bus Interface Unit (BIU)

This is the region of processor that acts as the interface between the processor and the rest of the system. It is this region that is responsible for bring the data and instructions from the system RAM to the processor. After obtaining this information, the bit separates to the appropriate region for further processing.

Components

A transistor is nothing bit an electrical controlled switch and when many of them are connected together in a specific circuit, they can be made to perfume more comply takes. This forms the basic of all processors where the complexity depends upon the number of transistors.

Processor


Sine a computer is a digital device, every thing that goes on inside a computer, from copying a simple to playing advanced computer game is composed of a steam of binary (Zeros and Ones) Signals shuttling between the various components of the computer. The processor is a digital device that acts on information set to it. Processor it in predetermined fashion and returns the result. It is the software that gives the processor. It’s matching instructions and tells it what takes to carry out. For this reason, the processor is divided takes sine all the takes carried out in a computer are either logical (Decision Making Takes That Decide the out come of a program or Where a particular piece of Data goes) or Mathematical (Involving Adding, Subtractions, Multiplications or either Functions on Numeric Data) The processor has regions in that can handle such data.
