What are CPU and RAM? What does RAM mean in a computer?

**The CPU (Central Processing Unit) is a very large-scale integrated circuit, which is the computing core and control unit of a computer. Its function is mainly to interpret computer instructions as well as process data in computer software.

**The processor mainly consists of combinators (ALUs, arithmetic logic units) and caches, as well as buses that enable the data, control and state between them. Together with internal memory and input and output (IO) devices, it is known as the three core components of electronic computers.

Random Access Memory (RAM), also known as "RAM", is the internal memory that directly exchanges data with the CPU, also known as main memory (memory). It can be read and written at any time, and it is fast, often as a temporary data storage medium for operating systems or other running programs.

Storage that the contents of a storage cell can be removed or deposited as needed, and the speed of access is independent of the location of the storage cell. This type of memory loses its contents when the power is off, so it is mainly used to store programs that are used for a short period of time. According to the working principle of the memory cell, random access memory is further divided into static random access memory (English:

Static RAM, SRAM) and Dynamic RAM (DRAM).

What exactly is the difference between RAM and ROM?

Tape RAM is random access.

RAM refers to the memory installed in the computer chassis, which is hardware memory, that is, the storage space of the memory provided by the merchant or the memory module installed by the owner himself. There are two types of memory in a computer, which are physical memory and virtual memory. Physical memory refers to a memory module, and virtual memory can be set by itself, which is to take out part of the useless space from the computer's hard disk and share it with the memory.

Some software needs to occupy a lot of virtual memory and physical memory, and the smoothness of the computer is mainly reflected in the size of the physical memory.

Machine RAM is not as simple as the general saying of the computer in the memory module, literally it is not difficult to understand the meaning of the board rather than the memory module inserted in the memory card slot, many early computer motherboards are onboard running memory without additional memory module expansion, because it is the cover state loss soldering on the motherboard without the problem of poor contact, the disadvantage is the obvious non-expandable memory capacity.

Applications with high requirements for RAM:

For most home computers, the biggest use of RAM is the operating system itself, and the rest are browsers, common apps and games, and the rest of the RAM resources are very small. A portion of the RAM is used to keep the browsers running basically, whether it's Windows or macOS, and the more RAM left, the more tabs can be opened with browsers like Chrome, Firefox, and Internet Explorer.

In addition, some ** also consume a lot of RAM, such as the text-only news network Wushen station does not have much pressure, and like Gmail or Netflix** it takes up more running memory. As the complexity of the application increases, more RAM is consumed. Simple games like chat apps or minesweepers hardly take up much of your RAM.

But huge Excel** or Photoshop files tend to consume 1GB of RAM. For professional engineering software, it is a big consumer of RAM, and at the same time, large-scale 3D games often put RAM to a greater test.

RAM (Random Access Memory) is the physical memory in your computer that stores running programs and data. If the data in RAM becomes cluttered or useless, it can cause your PC to slow down or crash. Here are a few ways to clean up your computer's RAM physical memory

Restart your PC: Restarting your PC clears all data from your RAM, so you can get your PC back up and running.

Close unnecessary programs and windows: Bridges or if you run many programs and windows at the same time, can cause excessive RAM usage. Closing unwanted programs and windows can free up RAM, which can make your PC run faster.

Use Task Manager: In a Windows Operational System, you can use Task Manager to see which programs are taking up a lot of RAM. Select the "Processes" tab in Task Manager and click on the "Memory" tab to sort by memory usage to find which programs are taking up more RAM.

You can choose to end these processes to free up RAM.

Use a cleanup tool: There are PC cleanup tools that can clean junk data from your RAM. These tools run automatically and clean up unnecessary data from RAM to make your PC run faster.

It's important to note that cleaning up RAM won't necessarily fix all slow or crashing PCs. If these problems occur frequently, there may be a problem with the computer hardware or software that needs to be further diagnosed and repaired.

RAM is running memory, referred to as memory, which is an element used in mobile phones to temporarily store data, which is equivalent to a memory module in a computer.

It can be read and written at any time, and it is very fast, and it is usually used as a temporary data storage medium for operating systems or other running programs. RAM will lose its storage content when it loses power, so it is mainly used to store programs that are used for a short period of time.

Phone speed and running memory methods.

The speed of the mobile phone system and the speed of the program run mainly depends on the size of the memory (RAM), which is consistent with the memory on the computer. If the memory is small, it will be slow, and if the memory is large, it will be fast.

If there is a lack of memory when running a program or game, this is related to the running memory of the system, and has nothing to do with the capacity of the C disk and E disk memory card, even if there are still hundreds of MB of space on your memory card, it is useless, what we need to solve is to release the running memory occupied by the program, so that the running memory is as large as possible.
