Processor

The Processor also central processing unit (CPU), interprets and carries out the basic instructions that operate a computer. The processor significantly impacts overall computing power and manages most of a computer’s operations. On a personal computer, all functions of the processor usually are on a single chip. Some computer and chip manufacturers use the term microprocessor to refer to a personal computer processor chip.

The CPU is a part of the hardware that carries forward the instructions of a computer program. It is trained to perform basic functions like arithmetic, logic and input/outfit operations in the computer system. In the computer, every instruction goes through the CPU, it doesn’t matter how small it is.


A CPU has multiple components which perform different work. It has an arithmetic logic unit that has a responsibility to perform simple arithmetic and logical tasks. It also contains a control unit that handles the various parts of the computer. It has the responsibility to read and interprets instructions from memory and convert them into a series of signals to start the operations of the other computer parts. The control unit also calls the arithmetic logic unit to perform the necessary calculations from time to time. In CPU operations, cache memory is used which is high-speed memory where instructions can be copied and retrieved quickly.

          summery of CPU

  • CPU is considered as the brain of the computer.
  • CPU performs all types of data processing operations.
  • It stores data, intermediate results, and instructions (program).
  • It controls the operation of all parts of the computer


RAM

RAM stands for Random Access Memory, and is used as a short-term memory storage space. The processor, also known as the CPU, provides the instructions and processing power the computer needs to do its work

Users typically are referring to RAM when discussing computer memory. RAM (random access memory), also called main memory, consists of memory chips that can be read from and written to by the processor and other devices. When you turn on power to a computer, certain operating system files (such as the files that determine how the desktop appears) load into RAM from a storage device such as a hard disk. These files remain in RAM as long as the computer has continuous power. As additional programs and data are requested, they also load into RAM from storage.

RAM also known as computer memory unit is that part of the computer hardware which handles all the memory and caching related operations of the processor. It has two separate registers that are managed by the CPU’s control unit. Data to be sent to the main memory or retrieved from memory is stored in the Memory Data Register (MDR). The desired logical memory address is stored in the Memory Address Register (MAR). The address translation is also known as address binding and it uses a memory map that is programmed by the operating system.

       THERE ARE TWO TYPES OF A RAM

  • Dynamic Random-Access Memory (DRAM)
  • Static Random-Access Memory (SRAM)

The difference between SRAM and DRAM are in how they refresh, or speed. SRAM is faster because DRAM needs to refresh quite often (thousands of times per second) whereas SRAM doesn’t.

In terms of seconds, DRAM gives access times of about 60 nanoseconds. SRAM does the same in 10 nanoseconds. Since the speed difference is so great, one would expect SRAM to be the most common type of RAM, but it’s not because it’s quite expensive.

What is the relationship between CPU and RAM?

 RAM (Random Access Memory) is an asset for the CPU (Central Processing Unit) to complete its tasks. If the CPU is a nail gun, RAM are nails. As the CPU processes tasks, runs applications, it needs/uses memory

RAM stands for Random Access Memory, and is used as a short-term memory storage space.

  • CPU is also storage long time 
  • RAM is also short temporoly time or short time RAM is work when computer is Running
