This article mainly introduces what the modern computer refers to, the article is very detailed, has a certain reference value, interested friends must read it!

Modern computer generally refers to general-purpose digital electronic computer, which is the mainstream in the electronic computer industry in the world today, and its internal processing is a kind of electrical signal called symbolic signal or digital signal; its main feature is "discrete". There can be no third symbol between two adjacent symbols.

Electronic computers are divided into analog computers and digital computers. Analog electronic computers came out earlier, and the electrical signals used internally simulate the actual signals of nature, so they are called analog electrical signals.

The accuracy of the analog electronic computer is poor; all the processing processes need analog circuits to achieve, the circuit structure is complex, the ability to resist external interference is very poor.

Digital computer is the mainstream in the electronic computer industry in the world today, which internally deals with a kind of electrical signal called symbolic signal or digital signal. Its main feature is "discreteness". It is impossible for a third symbol to exist between two adjacent symbols. Because of the difference of this kind of processing signal, its structure and performance are better than that of analog computer.

Digital electronic computer, referred to as digital computer. The internal information transmitted, stored and calculated are all digital in the form of electromagnetic signals. A typical digital computer consists of a central processing unit, a computer storage system and a computer input / output system.

The computer storage system includes a main memory and an auxiliary memory. The central processing unit and the main memory are called the central processor; the computer input / output devices and the auxiliary memory are called computer peripherals. The computer cannot work only with hardware, and there must be a set of "programs" that determine the rules and order of information processing. The same hardware with different programs can solve different types of problems. Computer programs and corresponding data and documents are called computer software, which includes computer system software, computer application software and computer support software. The organic whole composed of computer hardware and software is called computer system.
