b.         Class-2 Components.

c.         Class-3 Components.

Class-1 Components

Class 1 components are integral to the function of the computer system. Almost all Class-1 components are found inside the “casing”.Class-1 components of a microcomputer are as follows:

(1)    Casing.    

Computer Casing

The PC case is a thin sheet metal nook that houses the motherboard, control supply and different drives (HDD, FDD, Cd, and DVD). Cases are offered in two styles, work area and tower. Today the pinnacle write is prevalent. The motherboard and power supply are mounted and settled to inward mass of the packaging with screws. The drives (hard, floppy and Cd/DVD) mount in fenced in areas called drive straights at the inward front of the case. Typically the external front side of the packaging holds the power on/of catch, reset switch, sound yields, Compact disc/DVD Player faceplate and USB ports. Housings are found in various hues and styles. Show day's housings are called ATX packaging which remains for Propel Innovation Expanded. 

(2)    Power Supply Unit.    

Power Supply Unite

A control supply unit (PSU) changes over exchanging current (air conditioning) electric energy to low-voltage DC control for the inside segments of the PC This changes over the supply voltage (air conditioning 110 or 220V) to various voltages, for example, DC 5V, 12V and 3.3V. These are required inside the PC framework by almost every part inside the PC. There will be a cluster of connectors falling off of the unit, called "Molex connectors". These connectors are of various sizes with various stick designs. The power supply additionally has a fumes fan that is in charge of cooling the power supply, and also giving a hot air fumes to the whole case. It is critical to purchase a power supply that can oblige the greater part of the segments included.

(3)        Motherboard.           

The motherboard is the main circuit board in a PC.It is also known as “Main board” or “System board” It contains all the circuits and components that run the computer. Major Components found on the motherboard are: 

             (a)    BIOS

BIOS CHIPS

Fundamental Info Yield Framework is a non-unpredictable memory that contains arrangement data about the PC. It contains all the code required for the CPU to speak with the console, mouse video show, plate drives and specialized gadgets. At the point when a PC is fueled on it utilizes the Profiles 'boot code' to set up numerous required capacities that convey the PC to a point where it is prepared to work.
