The importance of computers in today's world ✨

the importance of computers It plays an increasingly important role every day. As far as the evolution of human knowledge has increased. As long as that means elaboration and complexity. to have more as well especially the development of technology which leads to more advanced work processes in every field The physical ability of humans may have limitations that are not supported. Therefore, it is necessary to invent equipment to support various operations, especially equipment that has the ability to record, manage, manage data. and computer processing

🔸 What is a computer?

Computers are essential devices. And it is widely used today. It is an electronic device or Electronic Device that has outstanding features in computing. especially the use of work in organizational units and various professional fields as long as its use in general matters such as entertainment, relaxation or communication.

However, the management style of computers Will be able to handle data management in a variety of ways, whether it is letters or numbers, including symbols. It is a set of commands that the system works. will rely on principles linked to programming serves to determine the working style or pre-display conditions to support reaction to the commands entered. from computer users

by each program In addition to being applied for a variety of purposes There are also specific format programs that are written directly. to support each activity or operations in various fields, especially as well Which we will see either computers or special devices equipped with a computer chip with a program to use, such as in medical devices. or general equipment in daily life Deposit-withdrawal or used in industrial plants which requires a computational system that must be accurate, accurate and fast, as well as support repetitive tasks stably

🔸 Computer Benefits

1. help create jobs

such as documents, reports, pictures, works of art, structural models, etc., which can produce workpieces accurately, quickly and efficiently.

2. Help create entertainment

Such as watching movies, listening to music, playing games, etc., relieve stress. have fun and spend free time to be useful

3. Help communicate

Whether near or far, computers can transmit information within a short period of time. save time and the cost is huge

4. Help find information

Computers are a good source of learning. For researching various knowledge, obtaining information as needed, which is considered to help facilitate users as well. which searching for information through the Internet You will get a wide variety of information and it is universal.

5. Help to solve social and country problems

computer aided planning Systematically assess the economic situation, trade, import and export goods, contributing to continuous progress in society and the country. Contribute to driving the economy of society to progress quickly

🔸 4 basic operating characteristics (IPOS cycle) of computers It consists of the following

1. Receiving input data (Input)

Input is a feature to receive data from the devices on which the receiving unit is installed. to be able to connect to the computer Whether it is a general connected device such as a mouse, keyboard or other specialized equipment.

2. The ability to process (Processing)

Processing is taking information whether it is from connected devices. or data from sending commands via the keyboard or control buttons that come with the computer. Bring that information to calculate according to the calculation principles that the program put out. This will result in the result according to the formula. It is used for many purposes such as calculating mathematical results. or calculations to display results as images, light, sound, etc.

3. Ability to display (Output)

The display stage is a data-driven stage. From the processing presented under the terms of the program. or the condition of the device supporting the display or forward code information so that the display device connected to the computer Can be applied to the display according to the capabilities and technology of the device.

4. Storage (Storage)

Data storage is a prominent feature. The most popular use of computers. Even those who do not have much computer skills has relied on the ability to store data To store information that you want to keep, and in addition to the ability to store information. computer memory system will also be responsible for the temporary storage of the results of the processing. caused by running the operating system or program which has a temporary record to quickly bring it into complex processing which must depend on the ability of the structure of each computer primarily

Computer or Computare is a name that comes from the Latin language. It means counting or dictionary calculation. By referring from The Royal Institute's Edition, B.E. 2525, will have the message that

"Automatic electronics acting like a brain It is used to solve simple and complex problems by mathematical methods.”

computer work There will be work with data structures (Data Structures). Data structures are divided into each level as follows.

🔸 Bit-level structure

Bit is the smallest data structure. Only number formats are supported. and can be used from digit 0 or number 1 only

🔸 Byte level data structure (Byte)

Bytes are supported in addition to numbers. which can support any character, letter or special symbol and symbols, which only supports 1 character, which if compared to bits, 8 bits equal 1 byte

🔸 Field

A field is a name for a data structure that consists of one or more bytes or characters, such as the name and noun of each data item.

🔸 Record

Record means data from one or more fields combined into a record, such as a combination of first and last name, or other information.

🔸 Files (Files)

A file is a level structure in which more than one record is joined together. and have related content and popularly viewed in the form of an easy-to-understand name “data file”

🔸 Database

A database is a structure at the level of storing multiple files together.

In addition to having a level of data structure. There is also a matter of data volume. which measures the size of the data It will consist of the following

- 8 Bit = 1 Byte (byte)

- 1,024 Byte = 1 KB (kilobytes)

- 1,024 KB = 1 MB (megabytes)

- 1,024 MB = 1 GB (Gigabytes)

- 1,024 GB = 1TB (terabytes)

Principles and work processes that are outstanding in terms of The four basic behaviors including a systematic data structure management model and combined with efficiency that is driven by High-performance hardware production with continuous development As a result, computers can be used in a wide variety of fields.
