Difference between RAM and CPU

Ram and CPU are both important computer components, but they have different functions. The RAM is responsible for the short-term memory of the computer, while the CPU is in charge of performing all the calculations. When choosing a computer, it’s important to know which type of processor and amount of memory you need. In this blog post, we will discuss the difference between RAM and CPU and give you some tips on how to choose the right one for your needs.

What is RAM?

RAM is an acronym that stands for Random Access Memory. RAM is a type of computer memory that can be accessed randomly, meaning that any piece of data can be accessed without having to go through the entire body of data. RAM is used to store temporary data that the computer needs to access quickly. This can include data that the computer is currently using, as well as data that the computer anticipates needing in the near future.

RAM is a vital part of any computer system, and it is important to choose the right type and amount of RAM for your needs. Too little RAM can lead to slow performance, while too much RAM can be wasted if it is not being used. The best way to determine how much RAM you need is to consult with a professional or use an online RAM calculator.

What is a CPU?

A CPU is a central processing unit, the main chip in a computer that reads and executes program instructions. The CPU is also known as the microprocessor. It handles all instructions sent to the computer, whether they come from the keyboard, mouse, disk drives, network, or other devices.

  • The CPU carries out each instruction in order to perform the basic arithmetical, logical, and input/output operations of the system. Newer CPUs can process billions of instructions per second.
  • They are typically packaged in a single integrated circuit known as a microprocessor chip. CPUs are attached to numerous support chips that handle communication with peripheral devices, memory management, and other specialized tasks. The entire assembly is housed inside the computer’s chassis and connected to the motherboard.
  • CPU manufacturers produce miniaturized versions of their chips for use in portable computers and handheld devices such as cell phones and digital watches. CPU speeds are measured in megahertz (MHz) or gigahertz (GHz); one MHz equals one million cycles per second, while one GHz equals one billion cycles per second.
  • CPU speed is not the only factor that determines overall performance; the number of CPU cores, cache size, bus speed, and memory type also play a role. When shopping for a new computer or upgrading an existing one, it’s important to consider all of these factors to ensure that you’re getting the most bang for your buck.

Difference between RAM and CPU

RAM and CPU are two important components of a computer. RAM is responsible for storing data and programs that are currently being used, while the CPU is responsible for processing data. RAM is generally faster than the CPU, but it is also more expensive. RAM is also volatile, meaning that it will lose its data when the power is turned off. CPU, on the other hand, is non-volatile, meaning that it can retain its data even when the power is turned off. RAM is also limited in terms of capacity, while the CPU is not.


We hope that this article has helped clear up any confusion about the difference between RAM and CPU.
