Single Edge Contact (SEC)

Single Edge Contact (SEC):-

                                  Pentium- II\III chips are characterized by their single edge contact SEC cartridge design. The processor, along with several l2 cache chips, is maintained on a small circuit board (much like an oversized memory SIMM), which is than sealed in a metal and plastic cartridge. The cartridge is then plugged into the motherboard through an edge connector called slot, 1 that looks very to an adopter card slot.

The Central Processing Unit (CPU)

The Central Processing Unit:-

The Central Processing Unit or CPU is also called the Brain of a Computer. It is a very complex integrated Circuit. It is build up of millions of tiny components integrated together. It is mainly divided into 2 units.
Arithmetic and Logic Unit (ALU)

Control Unit (CU)

Arithmetic and Logic Unit (ALU):-
The arithmetic and logic unit is the place where main processing is done. It performs Arithmetic Calculation (addition, subtraction, multiplication and division), while Logic unit performs Logical computations (compare objects and numbers with logical statements. Hence ALU manipulates the data.

Control Unit (CU):-

Control Unit maintains, orders and Controls the processing activity in the CPU. It directs the sequence of Operations.
