This document defines several common computer science acronyms and terms, including GPRS, TCP, IBM, ASCII, and CBI. It then discusses computer architecture as the logical structure and organization of a computer system, including its parts and how they relate. The document also defines the arithmetic logic unit as the electronic circuitry that performs arithmetic and logical operations on data using registers, and is used to execute calculations.

Architecture
In computer science, computer is a set of disciplinesthat
describes the part of computer system and their relations.
Computer architecture deals with the functionalbehaviorof a
computer system as viewed by a programmer. It can also be
described as the logical structure of the system unit that
housed electronic components. The computer architecture
forms the back bone for buildingsuccessful computer systems.
Arithmetic Logic Unit (ALU):-

2. The arithmetic logic unit containsthe electronic circuitry that
executes all arithmetic and logical operationson the available
data. It is used to perform all arithmetic calculationsand logical
calculations.Logical unit performs comparison of numbers,
letters and special characters. ALU uses registers to hold the
data that is being processed.
