Introduction Introduction Click on the image to zoomMotherboard, Processor and Memory form the main components of a computer system.Motherboard is the main circuit board of a computer. It contains connectors and ports for attaching additional boards and peripheral devices. It has multiple controller chips on the motherboard to control standard devices such as keyboard, disk drive, etc. All the controller chips together are called as chipset.Processor, sometimes referred as CPU (central processing unit), performs the actual processing of data. The data is obtained, via the system bus, from the main memory and the results are then sent back to main memory via the system bus. Apart from computation, the processor controls and co-ordinates the operations of major components.The CPU has two main components, the Control Unit & Arithmetic Logical Unit (ALU).Memory, sometimes referred as Main Memory, is an electronic component that stores programs and data either permanently or temporarily before transmitting between CPU and I/O devices.Introduction Click on the image to zoomMotherboard, Processor and Memory form the main components of a computer system.Motherboard is the main circuit board of a computer.

ProcessorProcessorThe CPU is a microchip, installed on a motherboard that performs calculations and coordinates with the hardware components.Most of the calculations take place in the Processor (CPU). The computing power of the CPU is the most important element in the computer system. On a small workstation and personal computer, the CPU is housed in a single chip called a microprocessor. On bigger computers such as servers CPUs require one or more printed circuit boards to house multiple processors.ProcessorThe CPU is a microchip, installed on a motherboard that performs calculations and coordinates with the hardware components.Most of the calculations take place in the Processor (CPU).

Processor ComponentsProcessor ComponentsThe CPU has two main components, the Control Unit & Arithmetic Logical Unit (ALU).The Control Unit controls getting the instructions from the main memory and its execution. Other tasks include, control of input and output devices and passing the data to the ALU for computation.The Arithmetic Logical Unit (ALU) performs arithmetic operations on integer (whole number) and real (with a decimal point) operands. It also performs logical operations (equality, greater than and less than) between operands.Processor ComponentsThe CPU has two main components, the Control Unit & Arithmetic Logical Unit (ALU).The Control Unit controls getting the instructions from the main memory and its execution.

Popular CPU ChipsPopular CPU ChipsThe processor controls the entire computer system. This includes the operating system, application software, games, device peripherals, etc.There are many types of processor (or CPU ) chips available in the market today. The most popular is the Pentium class chips from Intel Corporation. Each new chip is an enhancement on speed & performance over the previous chips.The rate of speed at which a processor executes commands is measured by clock speed, often referred to as MHz (megahertz). The processor needs fixed number of clock cycles to perform each instruction. The faster the clock speed, the more number of instructions it can execute, thus resulting in a faster computer system.Popular CPU ChipsThe processor controls the entire computer system.

Different Types of CPU Chips: (only Pentium Class Chips)Pentium:Pentium is the fifth-generation x86 architecture microprocessor released by Intel Corporation in 1993. It succeeds the 486 processor. Though it was named as Pentium this chip was actually to be named 80586 or i586.Intel first introduced the Pentium in two versions: 60MHz and 66MHz. The 60MHz version though it works fine, it was slow & didn't quite pass the 66MHz quality-control cut. Hence 66MHz version was released.Pentium has 3.1 million transistors which use a 32-bit address bus, 64-bit data path, 16K on-chip cache and it has speed which varies from 60MHz to 200MHz. The processor is a combination of two 486DX chips in one larger chip. The advantage of this architecture is that each chip can execute instructions independent of each other. This type of parallel processing ability is called super scalar.

Different Types of CPU Chips: (only Pentium Class Chips) (Cont...)Different Types of CPU Chips: (only Pentium Class Chips) (Cont...)Pentiums require special motherboards, because they run significantly hotter than previous processors. They require a heat sink on top of the processor to absorb and ventilate the heat.Some of the other important changes Pentium had from the 486 are:Superscalar architecture - The Pentium has two data paths that let it complete multiple instructions per clock cycle. The architecture has two pipes called "U" and "V". Pipe "U" can execute any instruction whereas the pipe "V" handles simplest instructions.64-bit data path - Assists in extracting double the amount of information from the memory on each fetch when compared to 32 bit data paths.MMX instructions- This technology contains SIMD instruction set designed to use in multimedia applications.Different Types of CPU Chips: (only Pentium Class Chips) (Cont...)Pentiums require special motherboards, because they run significantly hotter than previous processors.

Pentium Over Drive processors were released at speeds of 63 and 83MHz.Intel introduced MMX technology, this version of the Pentium had three new features, it includes 57 new instructions for better video, audio, and graphic capabilities. The cache was doubled to 32KB and it featured Single Instruction Multiple Data (SIMD) technology, which enables one instruction to give instructions to several pieces of data rather than a single instruction per piece of data.PentiumIntel 486 was nearly of the same speed as that of a first-generation Pentium.

Pentium OverdrivePentium OverdriveIntel introduced Pentium Overdrive processor as an upgrade option for older 486-class computers.Pentium Overdrive has the capability to enhance the 486 machines performance without having to pay the price for a full Pentium chip. Installing an Overdrive chip is simply a matter of replacing the existing CPU with the Overdrive CPU.It was designed to run at approximately two and a half times the motherboard's bus speed. Yet it had 2 major trade offs. First, Overdrives were only 32-bit processors, whereas Pentiums were completely 64-bit. Second, the Overdrive ran just as hot as a conventional Pentium, needing proper system ventilation to withstand the additional heat.Pentium OverdriveIntel introduced Pentium Overdrive processor as an upgrade option for older 486-class computers.Pentium Overdrive has the capability to enhance the 486 machines performance without having to pay the price for a full Pentium chip.
