Concept Of Hardware and Software
Computer software consists of electronically stored instructions or data, while hardware includes storage and display devices. Software is divided into system software (operating systems, utilities) and application software (user programs). Sometimes, the line between software and hardware blurs, as for buying software, you need hardware.
PC Specification
A personal computer (PC) is a type of microcomputer capable of handling single user computer operations and is becoming very popular in the market. Early PCs had low speed and no hard disks. PC-XT improved speed with Extended Technology. PC-AT, starting with 286 to Pentium IV, represents Advanced Technology.
Motherboard
A motherboard is a computer's main circuit board containing basic circuitry and components. It houses the CPU, controller circuitry, bus, and sockets for daughter boards. Common components include:
- Microprocessor
- (Optional) coprocessors
- Memory
- Basic input/output system
- Expansion slots
- Interconnecting circuitry
CPU Properties
The performance of a PC depends on CPU properties, determined by microprocessor specifications. Most PCs use Intel's 8086 family (80386, 80486, Pentium, etc.). Key properties:
- Clock Frequency: Specifies CPU execution speed. Pentium ranges from 500 MHz to 1 GHz; 80486 is 66 MHz
- Data Bus Width: Number of lines available for data transfer. Pentium is 32-bit; 80386 is 16-bit.
- Address Bus: Memory access capacity. CPU can access a memory by putting address on the address bus. Pentium has a 32-bit address bus (1 GB memory); 8085 has a 16-bit bus (64 KB memory).
- Serial Port: Determines availability of serial communication for peripherals.
