Bus slot or expansion port, an expansion slot is a connection or port located inside a computer on the motherboard  that allows a computer hardware expansion card to be connected. Types of Standard Expansion Bus Slots 1.Industry Standard Architecture (ISA) Bus Slot:   Expansion slots which are used to enhance the features of the PC.  ISA  bus is 16 slot bus present in  80286, 80386, 80486,and Pentium systems.  The ISA card is configured through jumpers or Swithches.  All modern computers today no longer included the ISA slots. Examples of ISA devices: Network card Sound card  Video card 2. Peripheral Component Interconnect (PCI) Bus slots:   It supports plug and play and it is self -configuring.  It operates at a speed of 33MHz or 66 Mhz  It is a 64 bit bus Communicates with processor using a bridge circuit Examples of PCI devices:  Modem  Network ...

Practical :Learning Outcome 1 of Unit 4 AIM: To setup the computer system. Equipments and Components Required:  Theory: The Mother Board There are primarily two types of motherboards, AT motherboard, and ATX motherboard. AT motherboards. The AT and ATX motherboards differ in the form factor. Full AT is 12" wide x 13.8" deep, and Baby AT is 8.57" wide x 13.04" deep. Full-ATX is 12" wide x 9.6" deep and Mini-ATX is 11.2" wide x 8.2" deep. Other major differences include power supply connector and keyboard connector. AT has 5-pin large keyboard connector, whereas ATX has 6-pin mini connector. Similarly, AT has single row two connectors +/-5V, and +/-12V, whereas ATX motherboard has double row single connector providing +/-5V, +/-12V, and +3.3V.  The important constituent components of an ATX Motherboard are given below:  1. Mouse & keyboard 2. Usb 3. Parallel port 4. Cpu chip 5. Ram slots 6. Floppy controller Port ...
