Answer analysis
1. [Answer] A
[Analysis] The working principle of "stored program" was proposed by the American Hungarian scientist von Neumann, so it is called von Neumann's principle. Its basic idea is stored program and program control.
2.【Answer】D
[Analysis] Artificial intelligence is the study of how to make computers do things that are usually thought to require human intelligence. Option D is a data processing application.
3.【Answer】D
[Analysis] The internal operations of the computer are automatically controlled and executed according to pre-programmed programs, without manual intervention.
4.【Answer】A
[Analysis] A Chinese character font of 16X16 dot matrix occupies 16X16/8 = 32 bytes, and 400 Chinese characters occupy a total of 32 X 400 = 12800
5.【Answer】D
[Analysis] According to the working principle of computers (processing objects), computers can be divided into digital computers, analog computers, and digital-analog hybrid computers; according to the functions and uses of computers, computers can be divided into general-purpose computers and special-purpose computers; according to the scale of computers, computers can be divided into Computers are divided into supercomputers, mainframes, minicomputers, microcomputers, workstations, etc.
6.【Answer】A
[Analysis] RAM is divided into static RAM and dynamic RAM. The former is fast, has low integration, and does not need to be refreshed regularly; the latter needs to be refreshed frequently, has high integration, and is slow.
7.【Answer】D
[Analysis] A wired network is a computer network connected by coaxial cables, twisted pairs and optical fibers, and is not an application of Internet of Things technology.
8.【Answer】A
[Analysis] The method of converting hexadecimal numbers into decimal numbers is to expand by weight. The hexadecimal number 2BA is equal to the decimal number 698.
9.【Answer】B
[Analysis] A computer instruction is a command that instructs the computer to perform a certain operation. It consists of a string of binary numbers and can identify whether the content stored in the register is data or an address.
10.【Answer】D
[Analysis] 1KB=1024B, 1B is one byte. A byte has 8 binary bits, so 1KB = 8×1024 binary bits.
