We are often asked to explain the difference between RAM and CPU and in our experience, it can be quite a difficult task. In this blog, we will explain the differences between RAM and CPU, why you need to know the difference and how you can get the most out of your computer.
RAM stands for Random-Access Memory. A computer’s RAM stores data from applications that are currently running. CPU stands for Central Processing Unit. A computer’s CPU processes data. The CPU is the part of the computer that executes programs. RAM is the place where data is held temporarily for the CPU to work with. When you work on a document in a word processor or play a video game, the information being worked on by the CPU is stored temporarily in the RAM.
Why Do You Need to Know the Differences Between RAM and CPU?
A CPU or central processing unit is a computer chip that carries out the instructions of a computer program by performing the basic arithmetic, logic, control, and input/output operations specified by the instructions.
A computer’s CPU is the single most important element of performance. How fast a program runs depends on how fast the CPU can execute instructions.
A CPU consists of a control unit that fetches instructions, decodes them, and executes them, and a number of functional units that are responsible for fetching operands, performing the operations, and writing the results.
RAM is the main memory of the computer. It is also called the volatile memory because the data available in the RAM at any time is washed out as we shut down the computer. RAM acts as an intermediate device between CPU and Secondary storage devices.
The data needed by the CPU at any time first comes to the RAM from secondary storage devices and then is provided to the CPU for execution when needed.
How Is RAM Different From a CPU?
The RAM (Random Access Memory) and CPU (Central Processing Unit) are two of the most important components in a computer system. Both are used to process data and execute applications, but they are not created equal.
The CPU is the brain of the computer. It is responsible for executing the instructions written in your computer’s code. The CPU is the component that most directly affects the performance of your computer.
The RAM, on the other hand, is an intermediate storage location for the CPU. It is responsible for temporarily holding data and code that has been requested by the CPU.
How Do RAM and CPU Work?
Here are 4 things to know about RAM (Random Access Memory):
- RAM holds data that is being currently used by the smartphone or PC, in order to execute the functions you perform on the device.
- Smartphones or PC have little RAM.
- More RAM allows a single computing task to be done faster.
- RAM is one of the components that you can upgrade.
Here are 4 things to know about CPU (Central Processing Unit)
- CPU is used to execute instructions in Smartphones and computers coming from RAM.
- CPU is the fastest device in smartphones or computers.
- Fast CPU ensures executing the instruction more quickly.
- Modern CPU has the capability of multitasking and multithreading.
How Does RAM Affect the CPU?
CPU is the fastest of all devices on the computer. It needs a storage device to provide the data quickly enough, so that it may process the data as quickly as possible and make room for the next instruction. For this purpose, CPUs need fast storage devices.
Unfortunately, the storage devices available today are slow and they can not perform well with CPU. For this purpose, RAM is included in between. The data that is needed by the CPU first comes in RAM from the storage device and is then provided to the CPU to be executed and converted into output.
More RAM in this case ensures fast computer processing because more data is available to the CPU to be executed at once. According to our recommendation, a computer should have at least 8GB of RAM to work with any latest and fast processor.
