CPU is the acronym for Central Process Unit. It is the main hardware item of the computer, which is also known as a processor. The CPU is responsible for calculating and performing user-determined tasks and is considered the brain of the PC.
Many err when confusing the CPU with what is actually the case of the equipment. The cabinet is just the support and protection structure of the machine’s internal components – basically a housing. The processor, on the other hand, is one of the internal parts.
CPU features directly influence how fast your programs will run on the machine. There are several types of processors on the market: 32-bit and 64-bit, single or multi-core, and compatible with different motherboards. The main manufacturers are Intel and AMD. The CPU is attached to the motherboard by means of a socket, a device that allows the processor to receive power to control the computer’s activities. There are also several types of sockets on the market and your choice limits the list of CPUs compatible with the machine.
Although there are 32-bit and 64-bit processors, 32-bit versions are virtually no longer sold, since 64-bit models allow the processor to work with a larger amount of data at a time, in addition, to support more RAM. For comparison purposes, while 32-bit processors do not recognize memories larger than 4 GB, 64-bit processors support up to 168 GB. It is important to note that even though the CPU is 64-bit, your Windows may be 32-bits, and this also limits the data that is worked by the machine.
The number of cores influences the ability of your processor to perform multitasking activities. The larger the number of cores, the greater your computer’s ability to handle multiple open programs at the same time.
Single-core, single-core CPUs are the oldest and can operate only one task at a time. Since they did not allow the performance of more than one task (with each new operation started, the computer slowed down), then the dual-core CPUs appeared, which doubled the performance of the processors and enabled them to work with multitasking activities much more efficiently.
