What are the basic principles of computers?

When the computer is running, it first takes out the first instruction from the memory, decodes it through the controller, and takes out data from the memory to perform the specified calculation and logical operation according to the instruction requirements, and then sends the result to the memory according to the address. Next, it takes out the second instruction and completes the specified operation under the command of the controller. It continues in this way until it encounters a stop instruction.

The most basic working principle of computers is that programs are stored in the same way as data, and instructions are retrieved step by step in the order in which they are arranged, and the operations specified by the instructions are automatically completed. This principle was first proposed by the Hungarian-American mathematician John von Neumann in 1945, so it is called the von Neumann principle.

What is the purpose of computer networking?

1. Computer network functions mainly include realizing resource sharing, achieving rapid transmission of data information, improving reliability, providing load balancing and distributed processing capabilities, centralized management and comprehensive information services.

2. Each computer in the network can serve as a backup for each other through the network. Once a computer fails, its task can be completed by other computers. This can avoid the phenomenon that a computer failure causes the entire system to be paralyzed in a single-machine situation, thereby improving the reliability of the system.

3. When a computer in the network is overloaded, the network can assign new tasks to less busy computers to balance the load, thereby improving the availability of each computer.

What are the computer encoding methods?

Refers to the way letters or numbers are represented inside the computer. Common encoding methods include: ASCII encoding, GB2312 encoding (Simplified Chinese), GBK, BIG5 encoding (Traditional Chinese), ANSI encoding, Unicode, UTF-8 encoding, etc.
