What is Processors? Various Types of processors in a computer system.

The terms processor, central processing unit (CPU) and microprocessor are commonly linked as synonyms. Most people use the word “processor” interchangeably with the term “CPU” nowadays, 

it is technically not correct since the CPU is just one of the processors inside a personal computer (PC).

The Graphics Processing Unit (GPU) is another processor, and even some hard drives are capable of performing some processing.

A  processor includes an arithmetical logic unit(ALU) and Control unit(CU), which measures capability in terms of the following:

It has the ability to process multiple instructions at a given time. Maximum number of bits/instructions.

Relative clock speed. Every time that an operation is performed on a computer, such as when a file is changed/deleted/modified or an application is open, the processor interpret the operating system or software’s instructions. Depending on the power and capabilities, the processing operations can be faster or slower, and have a impact on what is called the “processing speed” of the CPU.

The Processors are found in many modern electronic devices, including PCs, Smartphones, tablets, and other handheld devices. Their purpose is to receive input in the form of program instructions and execute trillions of calculations to provide the output that the user will interface with.

Each processor is constituted of one or more individual processing units called “cores”. 

Each core processes instructions from a single computing task at a certain speed, defined as “clock speed” and measured in gigahertz (GHz). Since increasing clock speed beyond a certain point became technically too difficult, modern computers now have several processor cores (dual-core, quad-core, etc.). They work together to process instructions and complete multiple tasks at the same time.

Modern desktop and laptop computers now have a separate processor to handle graphic rendering and send output to the display monitor device. Since this processor, the GPU, is specifically designed for this task, computers can handle all applications that are especially graphic-intensive such as video games more efficiently.

A processor is made of four basic elements: the arithmetic logic unit (ALU), the floating point unit (FPU), registers, and the cache memories. The ALU and FPU carry basic and advanced arithmetic and logic operations on numbers, and then results are sent to the registers, which also store instructions. Caches are small and fast memories that store copies of data for frequent use, and act similarly to a random access memory (RAM).

In a computer system Arithmetic Logic Unit (ALU) carries out all the arithmetical and logical operations on the basis of user requirement. It operates with integer numbers. The Floating Point Unit (FPU) manipulates floating-point numbers, which are those numbers that include a decimal in a number.

There is a register present in the computer motherboard. It holds the instructions that are received from the other parts of a computer. Register tells the ALU what processes are carry out from computer and stores the results of those operations.

Computer processors include L1 and L2 memory cache. The cache  memory allows the processor to store data locally, without retrieving it from the RAM(Random Access Memory). This helps a CPU faster and more efficient.

These numbers refer to send how many bits can be sent at the same time between different parts of the CPU. 32-bit processors are well-known for their power. Computers have been able to process up to 64 bits per second. The higher the bit count is, the more-faster the processor works.
