Motherboard Interview Preparation Guide

To clear Computer Motherboard CMOS password we will do these steps. Since CMOS is a special chip with its own battery, the best way to clear out a CMOS chip is to disconnect it from its power supply.

To clear the CMOS password you just remove the CMOS Battery or else you can also use a jumper settings.

It contains the following key components:<br>1.A microprocessor "socket" which defines what kind of central processing unit the motherboard uses.<br>2.A chipset which forms the computer's logic system. It is usually composed of two parts called bridges (a "north" bridge and its opposite, "south" bridge), which connects the CPU to the rest of the system;<br>3.A Basic Input/Output System (BIOS) chip which controls the most basic function of a computer, and how to repair it; and<br>4.A real-time clock which is a battery-operated chip which maintains the system's time, and other basic functions. <br><br>The motherboard also has slots or ports for the attachment of various peripherals or support system/hardware. There is an Accelerated Graphics Port, which is used exclusively for video cards; Integrated Drive Electronics, which provides the interfaces for the hard disk drives; Memory or RAM cards; and Peripheral Component Interconnect (PCI), which provides electronic connections for video capture cards and network cards, among others.

motherboard components are hdd,memory,processor,graphic card,net card,BIOS chip.

if ram is not working then we can change it and check that display if display not comes then we can say that it has problem with motherboard
first check in smps he will work right then check ram, ram is out in side slot then ruff the earesar ram is work in ok then check is cmos battery then last check is power cable and vga cable he will work ok then replace the motherboard.

8-bit Processor - 8085 / Z80 / 6800; 16-bit Processor - 8086 / 68000 / Z8000; 32-bit Processor - 80386 / 80486.

Cache memory is a small high-speed memory. It is used for temporary storage of data & information between the main memory and the CPU (center processing unit). The cache memory is only in RAM.

RAM: Read / Write memory, High Speed, Volatile Memory. ROM: Read only memory, Low Speed, Non Voliate Memory.

RAM- Random Access memory it is a Volatile Memory
volatile mean= when power is off data is loss ok
ROM- read only memory it is a non-volatile memory
it is read only memory we don't write this memory only read

8-bit Processor - 8085 / Z80 / 6800; 16-bit Processor - 8086 / 68000 / Z8000; 32-bit Processor - 80386 / 80486.

Microprocessor is a program-controlled device, which fetches the instructions from memory, decodes and executes the instructions. Most Micro Processor are single- chip devices.

A single chip CPU is called as Microprocessor.The CPU is made of two units namely the Arithmetic and Logic Unit and the Control Unit.It performs functions like executing the instructions given by the user program, controlling the I/O operations and the functions of peripheral devices

If you open your computers case, the motherboard is the flat, rectangular piece of circuit board to which everything seems to connect to for one reason or another.

Its the circuit board which contain processor,north bridge&south bridge and slots.

In primary storage device the storage capacity is limited. It has a volatile memory. In secondary storage device the storage capacity is larger. It is a nonvolatile memory. Primary devices are: RAM / ROM. Secondary devices are: Floppy disc / Hard disk.

Primary storage device is Ram where the instructions are stored for temporary and secondry storage is hard disk floppy cds etc.
