THE COMPUTER ARCHITECTURE

HARDWARE AND SOFTWARE

SOFTWARE

Software is formed by set of instructons that directs hardware to do some tasks for develop process

Is formed by:

Application software

Operating system

HARDWARE

Include physical components that are:

CPU (Central process unity)

This unity develope every process on pc

Storage

Data are put on the storage

Output devices

With output devices we receive signal of different type from computer

Input devices

With input devices we can send signal to pc

C.A. EVOLUTION

In the past computers were formed by single-core processors that could develop one process at a time. In the next years, after some studies and discoveries, we were able to insert many cores in one computer that could develop some process in same time.

INTRODUCTION TO C.A.

PRICIPLES OF THE C.A.

Hierarchical design

The systems are composed by level, one level depends on the previous.

Abstraction

Abstraction because the process is formed by bit, that are sequences of 0 and 1, so numbers are abstract things

Modularity

A system is devided by subsystems or MODULES that can intercact with each other

WHAT'S C.A.?

C.A. refers to the design and composition of a computer. It encompasses the hardware's components, instruction set, and interconnection of important elements in the case.
