The computer has become an important part of our life in today’s time. It is an electronics machine which performs various tasks like processes, calculations and operations based on instructions as directed by the user. The computer is one of the greatest inventions of science and now it becomes the main part of our life. The usage of computers in our daily chores has changed our life completely. Charles Babbage, also known with the title name ‘father of the computer’ invented the first computational device. As difficult tasks are done by computers easily so it becomes the essential tool of our work. Computers are used in various different ways depending on the type of work. They are used in almost all working fields like education, medicine, business, communication, entertainment etc. The importance of computer in different sectors of work is discussed briefly in the upcoming paragraphs.
Computers have various uses in the educational field which can significantly enhance performance in learning and teaching. The computer provides a lot of facilities in the education system.

Computers are the backbone of the banking system. Entire banking and financial system are dependent on computer technology. All the money transaction done by the banks or by other financial corporation is done by the same. Even the most used technologies like ATMs, internet banking etc. done with this technology only. The money deposited in our bank accounts is the digital money and the data stored on the computers keeps track of money which is deposited in the banks. All the electronic transactions taken care by computers and auditing of the fiscal year is done on the computers so we can say that it is impossible to do banking without the presence of computers. Even if we have to open an account in a bank at that time computer is needed because all the customer data will be saved on a respected bank’s server. Computers are required in the banks because of the need for high-speed processing; in earlier times there were no computers so it will take many days to do a transaction. This also reduces the expenditure of banks which was earlier spent on the staff because fewer men power is needed with the help of a computer. Also, it makes the whole working process convenient. Moreover, the different branches of the same bank can do intercommunication with this. This is all how computer technology becomes the heart of the entire banking system.
In the medical field also, the computer has very important works to do. The modern healthcare system completely depends on computer applications. The usage of computer systems in this field is gradual increases day by day. It is used everywhere from keeping the record of the patient to the surgery of a patient. In past times, patient’s records were written on the papers but now patient’s history is stored in the system and a printed copy of the record is also given to patients for their own use and record. It is very convenient for the employees to find out the required record on a computer just they have to give search command by entering right references instead of finding the files from the storeroom. They are also used in the medical laboratories for the diagnosis of diseases and the medical applications installed in computers help the research department to make their research in an easy and accurate way. It will take a few moments to get the result of a test whereas it’s a very long process if it is done manually by lab technicians. Nowadays, computer-assisted surgeries done in the hospitals which increase the accuracy rate of the surgery and make the whole process simple for the doctors. So, we can say that computers are life-saviours.
Computer technology plays a key role the transportation also. At present, there are hundreds of features applied in the vehicles which are totally computational components and also very fruitful for our journey as well as security purposes.

This will make our journey comfortable as we can choose the seats of our choice. Secondly, whole air traffic and air transportation system even railway systems are controlled with the help of this technology. Moreover, we can check the weather forecast on computers over the internet before travelling which results in a safe journey. Further, the computer application called navigation helps a lot while we travel to an unfamiliar place which is far from our hometown. We do not have to ask anybody about the way where we want to reach. We just have to enter our destination details and automatically a route will be created by that computational device and guide throughout the whole journey until you reached there. These are major uses of computational technology in transportation.
Computers are used in the industrial sector in various different types of chores. Firstly, as we know that industrial work is very rough and tough, so it is very difficult for the humans to move big parts here and there, for this, engineers invented the robots and the various other machines which can do the dangerous tasks and reduce the risk of life as well as work time. These machine and robots are controlled by the computers and operated by the computer operator. They work according to the command given by the operator on the system. After that, the computer is mainly used in the designing work. For making the designs of the products which manufacturers want to produce firstly their designs are made on computers using various applications and after that manufacturing of product will be started. Also, for the huge manufacturing, automated production systems are needed which will do the repeated task and increase the production of the company by using less time. All these automated systems are operated and controlled with the computers. This is how the computer becomes an essential part of the industrial sector.
