A computer is a machine that is capable of accepting data, processing it, and displaying the appropriate output. It can also store data and perform a set of complex calculations to accomplish complicated tasks. These calculations are performed by the central processing unit (CPU) of the system. CPU is also known as the microprocessor which is the heart of the system.
Identifying the Processor :
The microprocessor requires information to process the data. It retrieves the information from the external memory such as RAM. This process of retrieving the instruction from the memory is time consuming and slows down the processing. The latest microprocessors have memory known as level 1 (L1) cache built into the microprocessor.
To identify a processor you need to consider the following factors :
- Clock Speed
- L2 Cache
Operating Voltage of Microprocessor :
Intel Motherboard support various voltage settings in the range of 1.2 V to 2.5 V to work with many processors. Intel Pentium and AMD processors operate in varying voltages and the voltage setting it automatically detected by them.
Types of Processor :
The launch of Intel Pentium microprocessor in 1993.
- Pentium – ||
- Pentium – |||
- Pentium – 4
- Core 2 Duo
- Core 2 Quad
- Core – i3
- Core – i5
- Core – i7
- Core – i9
FEATURES OF INTEL PROCESSOR :
- EIST Feature: Enhanced Intel Speed Step Technology.
- EDB Feature: Execute Disable Bit.
- Intel Turbo Boost Technology (Performance on Demande)
- Smart Cache
- Intel 64 Technology
MICROPROCESOR SOCKETS :
The Socket on the motherboard connects the microprocessor to the motherboard. The microprocessor or socket has pins that allow the processor to communicate with the motherboard. These motherboards use the zero insertion force (ZIF) to install processors on the motherboard.
Socket PGA370 :
Socket 370 supports microprocessors that have 370 pins. In this socket, the pins are arranged in six rows. The microprocessor for this socket has the L2 cache built into the microprocessor. This socket supports Celeron 2 and Pentium ||| microprocessors.
Socket PGA478 :
Socket 470 supports microprocessors that have 478 pins. The microprocessors for this socket have the L2 cache built into the microprocessor. socket 478 is used with an Intel Pentium 4 microprocessor.
Socket LGA775 :
Socket LGA 775 is developed by Intel. It is used with the latest processors such as the Intel Pentium 4 Extreme Edition Processor, Intel Pentium D processors, Intel Pentium processors, and the Intel Pentium 4 Processors with Hyper-Threading Technology. This socket also supports 64-bit computing technology.
HEAT SINK :
A heat sink is a component that is used to provide cooling to an electronic device. The heat sink absorbs heat from the electronic device and distributes it to the surrounding environment. Most of the processors are equipped with a heat sink that absorbs all the heat from the processor and distributes it to the surrounding environment.
