CPU & MEMORY
CPU(Main Processor)
The main component of any motherboard is the main processor chip
It controls all the inner functions of the system.
The Central Processing Unit(CPU)functions as the brain of every PC.
CPU is responsible for the overall working of all components of the computer. It consists of two parts ALU & CU.
The Arithmetic Logic Unit performs arithmatic operations and conducts the comparison of information for logical decisions.
The Control Unit is responsible for sending/receiving the control signals from/to all components.
The central processing unit (CPU) is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions
The CPU is usually inserted into the socket provided for it on the motherboard, and is not soldered onto the motherboard, this makes its replacement, in case of any problem, very easy
Another advantage of having a socketed CPU is, one can choose the CPU according to ones requirement and budget.
Some of the common CPU chips by Intel are 8088,8086,80286,80386,80486,Pentium,Pentium-II,Pentium-III,Pentium-4 etc.
Memory
Memory is the place where computer stores the program(set of instruction telling the computer what you want to do),and data that help the program in carrying out its operations.
Basically two type of memory used in the computer.
1)RAM
2)ROM
RAM
Random Access Memory is a read/write type of memory which is used by the processor to keep program, data and intermediate results during the program executions.
It is a volatile type of memory, i.e. It lose its content when the power supply to it is switched off.
Volatile memory is computer memory that requires power to maintain the stored information.
Non-volatile memory is computer memory that can retain the stored information even when not powered. Examples of non-volatile memory include read-only memory
The Physical installation of RAM memory on the motherboard can take place in various ways.
1)DIP(Dual In-line Pin) memory chips were used on initial motherboards.
2)Later the SIMM(Single Inline Memory Modules) are most common memory module.
Read Only Memory(ROM)
ROM, as its name suggest is a read only type of memory.
One can not write into a ROM, data is written into it by the manufacturer.
One major advantage with the ROM is, it is nonvolatile type of memory i.e. it does not lose its content when the power supply to it is switched off.
A Motherboard normally contains one or more of these ROM chips.
The Memory capacity of a ROM varies from one type of system to another. 64KiloByte (KB) was normally sufficient for a XT system, whereas a P4 based motherboard requires 2Megabyte(MB) or more ROM.
