Introduction to Computer

Computers are the machines that can perform tasks or calculations according to set of instructions or programs. The term computer is derived from the word compute which means to calculate. Computer is an electronic device that can perform arithmetic and logical calculations faster. The first fully electronic computers, introduced in 1940s, were huge machines that required teams of people to operate. Compared to those early machines, today's computers are not only thousand times faster, they can fit on your desk, lap and even pocket. You must appreciate the impact of computer in our day-to-day life. The computer has been useful in reservation of tickets in Airlines and Railways, payment of telephone and electricity bills, deposits etc.

Advantages of computer

Computers are very fast due to which thousands of job can be performed within a short period of time.

Complex mathematical problems and logical operations can be solved by using this computer.

As computer is a versatile device, multiple task like communication, graphics, documentation can be done.

A huge amount of data can be stored and retrieved as it has high storage capacity.

Disadvantages of computer

Computers are machine hence, they have no brain so they work according to the program instructions set inside it.

It is an electronic device and it uses electrical sources to work, so it is very risky to store data and information on the computer independently because some electrical and electronic damages may damage the data. So we have to make regular backup of the data.

Since computers are very expensive device, it becomes beyond the capacity of general user. But now a day its price is going down than past.

Computers require dustless and temperature maintained environment for best performance

In order to make the program recognize the clicking of a button, the engineer should add an event listener to the JavaScript code.

An event is considered to be a vital part of JavaScript because a web page responds according to the event that occurred. Some events are generated by APIs and some are user-generated events. For example, clicking or moving the mouse button and pressing a key on the keyboard are user generated events.

In order to handle the user-generated events in JavaScript, an event listener is used. An event listener is a function or procedure in a JavaScript program that waits for an event to occur; such as pressing a key on the keyboard or clicking the button. Therefore based on the scenario given in the question statement, the engineer should use an event listener to his JavaScript code so that the code can recognize the click of the button.
