Computer Hardware

     The entity which made by the hard components, it is known as hardware. Also hardware is the entities which cannot be destroy by instruction.

     There are different kinds of hardware component. Such that processor, motherboard, ram, hard disk, disk drive that consist into a system unit.

 

      Processor: processor is a component which controls all of the systems. This is called by central processing unit (CPU).

      Motherboard: Motherboard is a holder of different components of a system unit like processor, RAM, harddisk , etc. It also known as printed circuit board (PCB). Motherboard has some expansion slot for attached expansion.

      RAM: RAM means Random Access Memory. It helps processor to complete process.

     Harddisk:  Harddisk is primary memory of computer systems. It is a medium of documents management. To store data harddisk separated by different tracks & sectors. If any problem of harddisk may show various signals, such that: Insufficient disk space; Bad partition table; Boot error;  current drive is no longer valid; cannot open catalog file; cannot perform a cycle copy; cannot read file allocation table; disk overflow; disk error writing; file allocation table bad; general failure; I/O error; etc.

There is some error recovery systems for resolve that problem. We can follow this.

     Another way there is more equipment in computer system, like Monitor, Mouse, Keyboard and so so.
