Computer Concepts 17 The following statement of the Notepad application is correct in (d)aIn "Notepad", you can complete the arrangement and saving of documents, but there is no printing operation BIn the "notepad", you can file information, and you can also insert **, ** and other information c

In Notepad, only one file can be opened.

d."Notepad" is exactly the same as "WordPad", both are small text-only answer choice D

The following statement about the Notepad application is correct (d).

A computer is an intelligent electronic device that can automatically perform numerical calculations and information processing at high speed with a pre-stored program.

Computers have two characteristics: functionality and programmability.

Functionality refers to the operation of data, which is realized into data calculation, performance data calculation, input and output processing, and result storage.

Programmability means that it can automatically, accurately, and accurately complete the operator's intent according to a series of instructions.

On the other hand, programming languages that express computer programmability are also undergoing a process of development from machine language, assembly language to high-level language, and gradually developing in the direction of closer to natural language.

The development of computer technology mainly revolves around the functionality and programmability of computers. On the one hand, the scale of integrated circuits on which computer hardware depends increases exponentially in accordance with Moore's law, and the speed of computers is also increasing rapidly close to geometric progression, and the functions that computers can support are constantly enriched and developed.

Computer (computer), commonly known as computer, is an electronic computer used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed. A computer that consists of a hardware system and a software system without any software installed is called bare metal.

It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc.

Inventor of the computer John von Neumann. The computer is one of the most advanced scientific and technological inventions of the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises, and institutions, and have entered the homes of ordinary people, becoming an indispensable tool in the information society.

The application of computers is becoming more and more common in China, after the reform and opening up, the number of computer users in China has been rising, and the level of application has been continuously improved, especially in the fields of the Internet, communications, and many other fields. From 1996 to 2009, the number of computer users increased from 6.3 million to 67.1 million, and the number of networked computers increased from 10,000 to 59.4 million. The number of Internet users has reached 100 million, and there are 100 million mobile Internet users on the wireless Internet, including 100 million mobile Internet users, ranking first in the world.

The first computer.

ENIAC is also known as a computer.

Accept user input instructions and data, and process the data and logic units of the ** processor to generate or store useful information.

The CPU contains a microinstruction set, which can be divided into two parts, the arithmetic logic unit and the control unit. The arithmetic logic unit is mainly responsible for program operation and logical judgment, while the control unit is mainly responsible for coordinating the work of each component and each unit. The data read by the CPU is read from memory.

The data processed by the CPU must also be written back to memory before the data is transferred from the memory to the output unit.

There are five parts: input unit, output unit, control unit inside the CPU, arithmetic logic unit, and memory.

Basically, the data is streamed through the memory and then transferred out, and the data will flow into the memory, which is the control instruction issued by the CPU. The actual data that the CPU has to process comes entirely from memory.

CPUs are classified according to the microinstruction set inside the CPU. They are the Reduced Instruction Set (RISC) and the Complex Instruction Set (CISC) system.

RISC: The micro-instruction set is relatively simple, the execution time of each instruction is very short, the completed operation is very simple, and the execution performance of the instruction is better, and if you need to do complex things, you need multiple instructions to complete. Common ones include:

SPARC series, Power Architecture series, ARM series.

CISC: The number of instructions is large and complex, and the length of each instruction is not the same. Because the execution of the order is more complex, each instruction takes a long time, but each individual instruction can handle more work.

Common CPUs include AMD, Intel, VIA, and other x86 CPUs. CPU code name 8086

The most important interface device is the motherboard. The motherboard is responsible for connecting all the devices together so that all the devices can coordinate and communicate. The most important component on the motherboard is the motherboard chipset . This chipset can bring all the devices together.

In addition, there are storage devices, display devices, network devices, etc.

Let's look at computers as an analogy with people

CPU: Brain.

Memory: The recording area in the brain stares at the defeated blocks.

Hard Disk: A memory block in the brain.

Motherboard: Nervous System components are connected.

Various peripheral equipment: hands, eyes, and other organs that communicate between the human body and the outside world.

Power source: Heart.
