A Computer is an electronic device that accepts input(s), processes that input and gives the desired output in form of useful device.
The main task of a computer system is to process given data so a computer system is also called data processing system.

A motherboard (sometimes alternatively known as the mainboard, system board, baseboard, planar board or logic board,is the main printed circuit board (PCB) found in.
It allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals.

Motherboards are produced in a variety of sizes and shapes called computer form factor.
As of 2007, most desktop computer motherboards use the ATX standard form factor.
Laptop computers generally use highly integrated, miniaturized and customized motherboards. This is one of the reasons that laptop computers are difficult to upgrade and expensive to repair.

The North Bridge is in charge of controlling transfers between the processor and the RAM, which is why it is located physically near the processor.

Read-Only Memory can be read but generally not changed.
It is non-volatile storage: it remembers its contents even when the power is turned off.
ROM chips are used to store the instructions a computer needs during start-up.

BIOS stands for Basic Input/output System. BIOS is a "read only" memory, which consists of low-level software that controls the system hardware and acts as an interface between the operating system and the hardware. Most people know the term BIOS by another name—device drivers, or just drivers. BIOS is essentially the link between the computer hardware and software in a system.

Most motherboards have connectors for additional case fans and integrated temperature sensors to detect motherboard and CPU temperatures and fan connectors which the BIOS or operating system can use to regulate fan speed.

Jumper pins are small protruding pins on the motherboard. A jumper cap or bridge is used to connect or short a pair of jumper pins. When the bridge is connected to any two pins, via a shorting link, it completes the circuit and a certain configuration has been achieved.
JUMPER PINS

Jumper caps are metal bridges that close an electrical circuit. Typically, a jumper consists of a plastic plug that fits over a pair of protruding pins. Jumpers are sometimes used to configure expansion boards.

Complimentary Metal Oxide Semiconductor Random Access Memory (CMOS RAM)
Motherboards also include a small separate block of memory made from CMOS RAM chips which is kept alive by a battery (known as a CMOS battery) even when the PC’s power is off. This prevents reconfiguration when the PC is powered on.
CMOS devices require very little power to operate.

The CMOS RAM is used to store basic Information about the PC’s configuration for instance:-
Floppy disk and hard disk drive types Information about CPU RAM size Date and time Serial and parallel port information Plug and Play information Power Saving settings

Cache memory is a small block of high-speed memory that enhances PC performance by pre-loading information from the (relatively slow) main memory and passing it to the processor on demand.
Most CPUs have an internal cache memory (built into the processor) which is referred to as Level 1 or primary cache memory. This can be supplemented by external cache memory fitted on the motherboard. This is the Level 2 or secondary cache.
implemented outside the die, it is referred to as the Level 3 (L3) cache.

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions..
CENTRAL PROCESSING UNIT (CPU)
![Page 28: Motherboard and processor](https://reader036.vdocuments.mx/reader036/viewer/2022062900/58cf31711a28ab00168b59b9/html5/thumbnails/28.jpg)
Working of processorThe working of processor mainly consist four steps i.e. Fetch, Decode, Execute and Write back. These steps are discussed below :
• Fetch : During the fetch step, the processor retrieves program instructions from memory.
• Decode : In this step, the instruction is broken down into parts.
![Page 29: Motherboard and processor](https://reader036.vdocuments.mx/reader036/viewer/2022062900/58cf31711a28ab00168b59b9/html5/thumbnails/29.jpg)
Working of processor
Execute : In the execute step, CPU performs
the operation implied by the program
instructions.Write back : During the write back step, the Processor writes back the
results of execution, to the computer's memory.

Basic knowledge about processor
Clock speed : Clock speed is a measure of how quickly a computer completes basic
computations and operations. It is measured as a frequency in
hertz. Generally this speed varies 2.4-3.4 GHz.
Core : A processor core is a hardware unit in the processor architecture that can execute
instructions sent to it.

control unit (CU) tells the computer's memory, arithmetic/logic unit how to respond to a program's instructions.
It directs the operation of the other units by providing timing and control signals.

An arithmetic logic unit (ALU) is a combinational digital electronic circuit that performs arithmetic and logical operation.
An ALU is a fundamental building block of many types of computing circuits.
The inputs to an ALU are the data to be operated on, called operands, and a code indicating the operation to be performed and, optionally, status information from a previous operation; the ALU's output is the result of the performed operation.

A processor register is a quickly accessible location available to central processing unit (CPU). Registers usually consist of a small amount of fast storage.

An instruction cycle (sometimes called a fetch–decode–execute cycle) is the basic operational process of a computer. It is the process by which a computer retrieves a program instruction from its memory, determines what actions the instruction dictates, and carries out those actions. This cycle is repeated continuously by a computer's central processing unit (CPU), from boot-up to when the computer is shut down.
