Main Components of Information Technology Systems

The main components of the Information Technology system are:

a. Hardware (Hardware)

It is a physical computer device. Hardware is divided into four, namely:

  • Input Device: That is the device used to enter data. Examples: Keyboard, mouse, microphone, and camera
  • Processing Unit: Commonly referred to as the CPU (Central Processing Unit). The center or brain of the computer. Consists of arithmetic and logic components (ALU), control unit, and Main Memory
  • Output Device: Device used to present or display data. Examples: Monitors, projectors, speakers, and others
  • Storage: Device used to store data. For example: Hard disk and flash.

b. Software (Software)

Is a computer program created with scripts in a particular programming language. Software is divided into 4 parts, namely:

  • Operating System: software that functions to manage the working system of all hardware and software on the computer. For example: Windows, MacOs, Linux, Chrome OS, and others.
  • Application: software that is used to perform certain tasks. For example: to make a letter using the Microsoft Office Word application.
  • Programming Language: instructions in the form of program code used to create application software. Examples of programming languages ​​can be seen in the article: 15 Most Popular Programming Languages
  • Query Language: used to process data in an application. Example SQL

c. Brain Devices (Brainware)

Braiware are computer users, for example: programmers, system analysts, database administrators, and others.

Classification of Information Technology

Information technology is classified into three parts as follows:

a. Classification of Information Technology Based on Processed Data

  • Analog Computer
  • Digital Computer
  • Hybrid Computer

b. Classification of Information Technology Based on System Function

  • Special Purpose Computer
  • General Purpose Computer

c. Classification of Information Technology Based on Size

  • Super Computer
  • Intermediate Computer
  • Small Computer
  • Mini Computer

The classification of information technology is likely to be discussed in detail in a special material.

Conclusion

That is a brief discussion of what is learned in the Introduction to Information Technology Lecture Material.

Hopefully this article can be a reference for making papers or presentation materials. Hopefully useful and don’t forget to share with other friends.

How is Information Technology Development?

The development of Information Technology is divided into two periods, namely: the Prehistoric Period and the Modern Period.

a. Prehistoric Time

At this time ancient people sent or obtained information by describing it on cave walls.

In addition to pictures, they also use smoke to communicate. For example, the Indians used smoke to signal warning, danger, or to call for help.

While writing began to be used as a means of communication in 3000 BC. In Indonesia, writing began to be used during the ancient kingdoms as a means of exchanging information.

b. Modern Times

The modern era is a golden age for Information Technology. Currently, there are many sophisticated tools and systems to make it easier for humans to communicate and manage information.

There are four well-known examples of Information and Communication Technology media, namely: Newspapers, Telephones, Televisions, and Computers.

4. The Role and Benefits of Information Technology

Currently, Information Technology plays an important role in everyday life. Broadly speaking, Information Technology has the benefit of helping and making it easier for humans to do everything.

The benefits of Information Technology have been applied in various fields. Among them are as follows:

a. Field of education

Examples of the use of Information Technology in the field of education include:

The National Examination, which used to be paper-based, has now been replaced by a computer. With UNBK (Computer-Based National Examination) will save time and money
Students can study online. There are many online learning media nowadays. For example, Ruangguru.com and Quipper School can make it easier for students to study anytime and anywhere.

b. Government Sector

Examples of the use of Information Technology in the government sector include:

To make a NPWP, the public does not have to come to the office or can be online.
Paying motor vehicle taxes in West Java can be done through e-commerce. So people don’t have to come and queue at the Samsat office.

Of course the two examples above are very effective and efficient for the community.

c. Economics

Examples of the use of Information Technology in the economic field include:

Buying and selling online via marketplace (bukalapak, tokopedia, shopee) or online stores.
There is an Online Ojek
The existence of online payments (gopay, ovo, funds)

d. Health / Medical field

Examples of the use of Information Technology in the health sector include:

To find out a disease we just have to access a halodokter. There, we’ll just have a free consultation with a general practitioner. and will recommend the right medicine for us.

There are still many examples of the use and role of information technology in the fields of education, government, health, and the economy. I’m sure you can provide another example.
