We are all aware of computers.Computers are unique among the innovations of modern science.The invention of the computer has brought many transformations throughout human civilization.It's like a human instrument wrapped in a mystery.Which is making the incomprehensible things of the human race easier in a moment.With the help of computer we are able to solve many complex tasks very easily.We are instrumental in acknowledging the contribution of computers for this.Because computers have brought a new horizon.But all things have their ups and downs.So in today's post I will try to highlight the good and bad aspects of computer among you.There are several downsides to computers.But most of it has positive aspects.The human race has evolved a lot today through all these amazing inventions.Computers are important and amazing discoveries of modern science.There is no specific Bengali word for computer.The only name in the world is the computer.In Bengali dictionary it means data collector.

What is a computer?

Almost all of us know what a computer is in the simplest sense.Computers are a special kind of electrical equipment.Which performs rational work through electric current.The computer converts electrical waves into its own signal.And solves problems caused by user commands.The word computer comes from the Latin word compute.The lexical meaning of the word compute is to calculate.That is why according to the lexical meaning of computer, it is called calculator.But at present this computer is not limited to just calculations.On the contrary, this device is being used extensively for many other purposes today.That is why it is said that computer has made our life very easy.Computer is one of the most important technologies in the world.Whose contribution is immeasurable.

The history of computers.

One thing that comes to our mind at the beginning is, who made the magical device called computer?The one whose name will come up in answer to this question is Cholas Babbage.Called the father of the modern computer.But the funny thing is that the history of computer making is about five thousand years old from today.An abacus instrument was invented in Greek civilization five thousand years ago.Which was used for calculation.This device was later used in many countries of the world including China.In 1642, the French scientist Besneis Pascal invented the mechanical calculator.Charles Babbage then researched the device to see if it could be improved.But the sad thing is that the work is not completed due to lack of necessary equipment and money.In fact, computer technology was introduced during the time of Alan Turing.The last modern computer was introduced in 1833.

Computers can be divided into three groups based on their structure and operation.Such as analog computers, digital computers, and hybrid computers.Digital computers can also be divided into four categories based on shape and application.Such as supercomputers, mainframe computers, microcomputers and mini computers.Microcomputers can be further divided into two types.One is laptop and the other is desktop.

Now let's talk about the computer brain.Older computers are just like the human brain.Which is known as the human instrumental brain of the modern age.Modern computers solve our various problems at the moment.He solves these tasks by applying the memories and information held in his head.The computer brain usually consists of three special parts.Such as central processing units, inputs and outputs.
The central processing unit is the brain of the computer.Because this part of the computer deals with any problem.And the job of the input is to take instructions according to the information.Input devices such as keyboard mouse disk antenna card reader digital camera etc.The output, on the other hand, is expressed as an indicative result obtained at the input.For example, monitors, printers, disks, speakers, projectors, headphones, these are the output devices of the computer.

With all the information we have been able to gain an idea about computers.Because a computer is a device through which we can be aware of everything else.And so it is a blessing for us.The computer options are endless to continue and improve our lives.
