Based on your own life, what are the functions of computers?

The key to the purpose of a computer lies in its software. Hardware is the material basis of computers, and software is the soul of computers. If your computer is a bare machine (no application software has been installed), you should first consider installing some useful application software. Of course, some software has too high hardware configuration requirements, especially some large-scale game software, but general application software does not have too high hardware requirements.

Things you can do:

1. Typing and typesetting (word processing software such as OFFICE is required);

2. Drawing and photo processing ( You need to install image processing software such as PHOTOSHOP);

3. Small games (of course you need to install game software, unless you just "dig mines"...);

4 , surf the Internet, browse news, and search for information;

5. Watch dumb movies and TV online (if there are no speakers and sound cards);

6. Stock speculation online

...

Things that cannot be done:

1. Listen to music and write music files (if you do not even have a sound card installed or a pair of headphones);

2. Print text materials (requires printer);

3. Scan pictures or text (requires scanner);

4. Make video calls online (requires microphone, Cameras, etc.)

Uses of Computers

We are now in the age of technology, and computers are used everywhere. From those encountered in daily life to sensitive high-tech ones, this chapter can help you understand the application of computers in different fields.

3.1 Education

Computer as a learning tool

Computer-assisted learning uses computers as learning tools. Currently, there are many computer-assisted learning software that use text, images, sounds, videos, animations, etc. to help students learn different subjects. At the same time, you can test the knowledge you have learned and get the test results immediately.

A large number of learning resources can also be found on the Internet, and students can also learn some extracurricular knowledge on their own.

Computers as teaching tools

Computers are also very good teaching aids. By using computers, teachers can use more interesting multimedia (images, videos, animations, sounds and text) effects to more clearly display teaching content, explain some concepts that are difficult to explain, and demonstrate some experiments that are difficult to actually conduct, so that Learning is more fun.

Computers as school administrative tools

With the help of computers, school administration can be more efficient. Schools can use computers to store and process large amounts of information, such as each student's personal records, class lists, test scores in various subjects, library books and materials, etc.

3.2 Entertainment

Computer Games

Computer games can be divided into adventure games, action games, educational games, intellectual games, simulation games, strategy games, etc., most of which Containing a large number of visual and sound effects, good computer games can trigger the imagination of game participants and provide them with the fun of challenge and the joy of success.

Film and TV production

Using computers, we can produce special sound and visual effects in movies or TV programs; currently, many science fiction or action movies use computer technology to assist production, bringing us new forms of entertainment.

Interactive TV

Now, we only need to connect a control box to enjoy the video service of our choice while sitting at home. You only need to select the video you want to watch, and the computer system will transmit the video through the phone line so that you can watch it on your TV at home.

3.3 Household appliances

Household appliances

VCR scheduled recording, washing program of washing machine, automatic temperature control of refrigerator and air conditioner, heating program of microwave oven, etc. controlled by a computer.

Smart home

The so-called smart home means that through programming, voice control or phone control, all the electrical appliances in the house are controlled by the computer and turned on and off on time.

3.4 Transportation

Traffic monitoring

Traffic lights, electronic road tolls, and sea, land and air traffic monitoring systems are all controlled by computers.

Deployment

The deployment of railway systems, trains, ships, and aircraft is all controlled by computers.

Ticketing

Ticketing systems such as automatic ticket vending machines, Octopus cards, etc. are all controlled by computers.

3.5 Communications

Telephone

The telephone systems in most countries have been computerized, which has further improved the sound quality, lines, and working environment of the telephone building.

E-mail

E-mail software allows people to send and receive messages over a computer network. It is a fast, economical and convenient method of transmitting information.

Real-time communication

Conduct online games, chat rooms, ICQ, Internet calls, video conferencing, etc. Video conferencing also allows people to have face-to-face calls with other people through computer networks.

3.6 Business

Financial Industry

The operations and records of various branches of financial institutions are all connected by computers. You can use automatic teller machines to deposit, withdraw money or transfer funds. , now you can use your phone, TV or computer to connect to the bank's computer system to 1. Check the account balance;

2. Perform transfer;

3. Obtain financial information.

Sales industry

Department stores and supermarkets use computerized point-of-sale terminals to read goods information (name and price), print invoices, control inventory, and connect systems Each point-of-sale terminal controls inventory levels and order quantities.

Service industry

Many service industries have begun to use computers to improve efficiency. Hotels can use computers and the Internet to book rooms, restaurants use computers to place orders and check out, and travel agencies use computers to book air tickets for customers. Hotels, etc., shopping companies use the Internet for shopping services, etc.

3.7 Office Applications

Office automation is the use of computerized equipment to handle office work. The following types of application software are commonly used in generally automated offices:

Word processing software

Word processing software can be used to create, edit, proofread, format and print documents. .

Spreadsheet

Spreadsheet software can perform calculations, analyze data, and display information.

Database

Database software can store, organize and update large amounts of data.

Presentation software

Presentation software can display reports or presentation materials to attendees during meetings.

3.8 Industry

In industry, many tasks can be assisted by computers. Two major areas include:

Computer-aided design

Engineers often use computers to design new products. With the help of computer-aided design programs, the design work can be accelerated, and the design can be tested on the computer before the product is officially produced.

Computer-aided production

Computers can manufacture products according to designs. Operators can program computerized CNC machines and use them to manufacture very complex and precise parts and improve product quality. .

3.9 Science

Weather Forecast

The Observatory uses large computer systems to process large amounts of data, produce weather maps, and issue weather forecasts to the public.
