Hardware Lesson 2

Motherboards
Motherboards are considered as the backbone of the computer, which provides us with an interface to connect our devices internally and externally.
There are 3 types of mother boards:-
1. AT : Advanced Technology
2. ATX: Advanced Technology Extended
3. BTX: Balance Technology Extended


AT Motherboards: (click picture to see bigger size)

· These are oldest type of motherboards.
· Mainly used in Pentium 1 and Pentium 2 computers.
· They had only one build-in port for the keyboard. (5 pin DIN). All other ports had to be connected separately.
· Not used now a days.

Hardware Lesson 2
· These are currently used types of motherboards.
· It has many built-in ports for mouse, keyboard, USB, Video, audio etc
· It come in 2 sizes :
1) Micro ATX (small)
2) Full ATX (Large) -Large boards have more slots and are more expensive.

BTX Motherboards (click picture to see bigger size)

· These are same as ATX the only difference is that it is designed in a way to reduce heat generated by devices.
· Its slots are placed in a manner to prevent one devices’ heat form affecting other devices. (it is kept little far from each other)

Hardware Lesson1

PORTS
These are located on the backside of the motherboard and are used to connect external devices. There are 3 types of ports:
A. Legacy multifunction ports
B. Standard single function ports
C. Modern multifunction ports

A. Legacy multifunction ports:
1) Serial Ports:
Hardware Lesson1
· It comes in 2 types à 9 pins and 25 pins.
· These ports are not used by latest devices.
· It supported devices like mouse, label printers, external modem, etc.
· Now-a-days we might have 9 pins serial port on the motherboard.

2) Parallel Port:
hardware
· This is also known as printer port.
· It supported devices such as printers, scanners, external/hard disk, CD Drives etc.
· Not used anymore.

B. Standard Single function ports:
1. Keyboard Port

Modems are devices used to connect to dial up internet or VPN network using our telephone line. Modems have 2 ports line-In and Line-out.



6. Network Port:

These ports are found on network cards and are used to create a computer network.


C. Modern multifunction ports:
1. USB (Universal Serial Bus)
· All latest devices connect to the USB port.
· It supports a wide range of devices such as printer, scanners, digital cameras, pen drive, external drives, mouse, keyboard, mobiles etc.
· There can be 2 or more USB ports on a motherboard. Also we can use USB HUBS to increase our ports.
· USB also supports Hot-swapping. (hot swapping; we can connect or disconnect at any time even when running a computer)
· USB can supports daisy chain connection, USB can support up to 127 devices through daisy chain.

2. Fire wire (1394)
· Fire wire is the advancement of USB and can support much faster speeds.
· It also supports devices such as USB.
· It supports Hot Swapping and daisy chain of up to 63 devices.
