Session 6 : The Personal Computer Connection Methods

The various PC connection methods are: 

-Ports 

-Personal Computer Connections 
-Serial Connections 
-Parallel Connections 
-Universal Serial Bus (USB) Connections 
-IEEE 1394 and FireWire Connections 
-Small Computer Systems Interface (SCSI) Connections 
-Parallel ATA (PATA) Connections 
-Serial ATA (SATA) Connections 

Let's see the details of connection


Port

A port is a hardware connection interface on a personal computer that enables devices to be connected to the computer. 



Personal Computer Connection 

A personal computer connection is a means by which a personal computer component is attached to other components to provide computing capabilities.




Serial Connections 

A serial connection is a personal computer connection that transfers data one bit at a time over a single wire. 



Parallel Connections 

A parallel connection is a personal computer connection that transfers data eight bits at a time over eight wires and is typically used to connect a printer to a system unit. 



USB Connections 

A USB connection is a personal computer connection that enables you to connect multiple peripherals to a single port with high performance and minimal device configuration. 



IEEE 1394 and FireWire Connections 

A FireWire connection is a personal computer connection that provides a high-speed interface for peripheral devices that are designed to use the IEEE 1394 standard. 





Small Computer Systems Interface (SCSI) Connections 

A SCSI connection is a personal computer connection that connects internal and external components to the system unit and provides for high-speed data transfer.


Parallel ATA (PATA) Connections 
A PATA connection is a personal computer connection that provides a parallel data channel from a disk controller to the disk drives. 



Serial ATA (SATA) Connections 

A SATA connection is a personal computer connection that 

provides a serial data channel between the drive controller and the disk drives. 




Summary

In this session, you learned that:
~The four primary components of a typical personal computer are system unit, display device, input devices, and external devices.

~The major components of the system unit are system board,CPU, memory, system bus, and storage devices.

~The various types of storage devices used in personal computers are FDD, HDD, optical drives, tape drives, and solid state storage devices.

~The various PC connection methods are ports, PC connections, serial connections, parallel connections, USB connections, IEEE 1394 and FireWire connections, SCSI connections, PATA connections, and SATA connections.

Session 5 : The type of Storage Device and System Board form factor

The type of Storage Devices 

The various types of storage devices used in personal computers are: 
Floppy Disk Drives (FDD) 
Hard Disk Drives (HDD) 
Optical Drives 
Tape Drives 
Solid State Storage devices 

Floppy Disk Drives (FDD) 
FDD is a personal computer storage device that reads data from, and writes data to, removable disks made of flexible Mylar plastic covered with a magnetic coating and enclosed in a stiff, protective, plastic case.

Hard Disk Drives (HDD) 
HDD is a personal computer storage device that uses fixed media, which means that the disk is built into the drive and 
the drives are not removed from the computer unless you are performing an upgrade or a repair. 


Optical Disks 
An optical disk is a personal computer storage device that stores data optically, rather than magnetically. 


Optical disks and drives come in several types, such as: 
CD-ROM 
CD-R 
CD-RW 
DVD-ROM 
DVD-R DVD+R 
DVD+R DL 
DVD-RW DVD+RW DVD-RAM 


Tape Drives 
A tape drive is a personal computer storage device that 
stores data magnetically on a removable tape that is enclosed in a tape cartridge. 

Solid State Storage 
Solid state storage is a personal computer storage device 
that stores data in special types of memory instead of on disks or tape. 





The System Board Form Factors 

The form factor describes the size and shape of the system board. 
Common System Boards are: 
-Full size AT 
-Baby AT 
-ATX 
-microATX 
-LPX NLX BTX

Session 4 : What is the Cooling System and important of it?

Cooling Systems 

Computer systems contain several components that require cooling
The computer case 
The CPU 
The power supply 
Some adapter cards 
Some hard disk drives 

Adapter Cards 

An adapter card is a printed circuit board that you install into a slot on the computer's system board to expand the functionality of the computer. 



Riser Cards 

A riser card is a board that plugs in to the system board and provides additional slots for adapter cards..

Session 3 : The all components of System Units

System Units Components

The system unit itself has several important sub-components, such as: 

System Board 
Central Processing Unit (CPU) 
Memory 
System Bus 
Storage devices 
Power Supplies 

The System Board 
The system board is the personal computer component that acts as the backbone for the entire computer system. 


The Central Processing Unit (CPU) 

The central processing unit (CPU), sometimes called microprocessor or just processor, is the real brains of the computer and is where most of the calculations take place. 



Memory 

Memory is the personal computer component that 
comprises the electronic storage areas in the computer. It can be considered either volatile or non-volatile. 



System Bus

The system bus is the main communication path between the CPU and memory. 



Storage Devices 

A storage device is a system unit component, such as a hard drive, that enables users to save data for reuse at a later time, even after the personal computer is shut down and restarted. 



Power Supplies 

A power supply is an internal computer component that converts AC power from an electrical outlet to the DC power needed by system components.

Session 1 : What are all the Categories of Personal Computer Components ?

In this chapter it contains 6 sessions

In this chapter, you will learn to:
Identify the major components of personal computers.
Identify the major components of the system unit.
Identify the various types of storage devices used in personal computers.
Identify personal computer connection methods.

Categories of Personal Computer Components 
There are four primary categories of components in a typical personal computer : 

System Unit 

Display Device 
Input Devices (Mouse, Keyboard, USB Flash...)

External devices (Microphone, Digital Camera, Speaker,Scanner, Printer, Network Device, External Drive... )
Before we move to the next part,
The question is :  What do you mean by System Unit, Display Device, Input Device and External Device?
