Presentation on Computer Hardware

ME 172Computer Programming Language Sessional

Charles Babbage, an Mechanical Engineering, originated the concept of a Programmable Computer

The technology is now developing day by day

MAIN COMPONENTS

PROCESSOR

Arithmetic Logic Unit

ALU

Control Unit OutputInput

Memory

PROCESSOR

Control Unit :

ALU : (Arithmetic Logic Unit)Perform mathematical, logical and decision operation

Directs all the processor operation

MEMORY

Register :

RAM :

Cache :

Special set of memory cell contained by CPU

(Random Access Memory)Read and write anytime by CPU command

Slower than register but faster than main memory

Input and output Device

Input and output Device

Input Device :Output Device :

Device that can command computer

Device that render the result of command

DATA STORAGE

Primary Storage :

Secondary Storage :

Register, RAM, Chace

Hard Disk Drive, Optical Storage Drive

DATA STORAGE

Computer represents data using binary numeral system

Data converted into a string of Bits

Common unit of storage is Byte

1 Byte = 8 Bits

MOTHERBOARD

A motherboard alternatively known as the mainboard, system board, planar board or logic board

It is the main printed circuit board (PCB) found in computers and other expandable systems.

MOTHERBOARD COMPONENT

PCI Slots

CPU Socket

ATX 12V Power Connector

CMOS Battery

SATA Connectors

RAM Slots

Mechanical part

Processor generate heat, so proper cooling system is required.

In this case MECHANICAL ENGINEER have to do a lot. 

The cooling system is a mechanical part in computer
