The Generation of Computer – Which Generation is Going On

The Generation of Computer – Which Generation is Going On



There are totally five Generation of Computers. The Generation of Computers is so called because the development of Computers was done in phases. In each Phase or Generation, the essential parts or components used was different. There are few questions which comes in our mind like. Which Generation of Computer is going on? How many Generation of Computers are there? What is the First Generation of computers? What is the Second Generation of Computer? What is the Third Generation of Computer? What is the Fourth Generation of Computer? What is the Fifth Generation of Computer? The Generation of Computer – Which Generation is going on?

To know the exact answer regarding all above queries, read below our interesting short description regarding Generation of Computer.

The Generation of Computer



How many Generation of Computers are there?


Till now, there are Five Generation of Computer. Now a days the Fifth Generation of Computer are used and under development. The details regarding each Generation of Computers is explained below. The Generation of Computer – Which Generation is going on?

The First Generation of Computer:



What is the First Generation of computers?


What is the period of First Generation of Computer?


The period between 1943 to 1958 is called as the First Generation of Computer. This Generation uses Vacuum Tubes as the main components of Computer System. The Vacuum Tubes are generally – 5 to 10 cm in length and often many of them are used in computers. They acquire entire room and often broke while handling. The Vacuum Tube is an electronic device used to amplify a signal by controlling the movement of electrons in an evacuated space. They were very expensive to operate and in addition to using a great deal of electricity, the first computers generated a lot of heat, which was often the cause of malfunctions. The UNIVAC and ENIAC computers are examples of first-generation computing devices.

The Second Generation of Computer:

What is the period of Second Generation of Computer?


The period between 1959 to 1964 is called as the Second Generation of Computer. This Generation of Computer uses Transistor as the main component of Computer Systems. The Bell Laboratory has developed Transistor capable of performing many of the tasks as done through Vacuum tube. But difference between them is Size of the components. The first successful computer uses transistor in 1959. Since the component size is small so Computer size was reduced. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors.

Second-Generation computers moved from cryptic binary machine language to symbolic, or assembly language, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time. For Example: COBOL and FORTRAN.

The Third Generation of Computer:

What is the period of Third Generation of Computer?


The period between 1965 to 1970 is called as the Third Generation of Computer. This Generation of Computer uses Integrated Circuit (IC) as the essential component of Computer System. Integrated Circuits (IC) was made of Silicon Chips, called semi-conductor, which drastically increased the speed and efficiency of computers. Instead of using punched cards and printouts, the computer uses Keyboards, Monitors and Interface with an operating Systems. Now the device can run many applications at one time where the central program was monitored by the memory. One of the major advantage of ICs is smaller in size. Again the computer size decreased and finally available to large audience.
Another feature of this period is that computer software became much more powerful and flexible and for the first time more than one program could share the computer's resources at the same time.

The Fourth Generation of Computer:

What is the period of Fourth Generation of Computer?


The Period between 1971 to Present is called as the Fourth Generation of Computer. This Generation of Computer uses Microprocessor (VLSI) as the main components of Computer Systems. Thousands of integrated circuits were built onto a single silicon chip so now the size reduced many times. Now the size of the computer reduces so much that it will fit on the palm of our hands. The CPU, memory and Input/ Output device are built on a single chip. The Macintosh introduced by APPLE, as one of the most powerful computer which uses Microprocessor inside it. The fourth generation also saw the development of Graphic User Interface, mouse and hand held devices.

The Fifth Generation of Computer:



What is the Fifth Generation of Computer?


What is the period of Fifth Generation of Computer?


The Future of Computer system is called as the Fifth Generation of Computer. The main technique which will be added in fifth generation are Artificial Intelligence, Expert Systems and Natural Language. The goal was to produce machines that are capable of performing tasks which is similar to humans, like - capable of learning, interacting with humans in natural language and preferably using both speech input and speech output. Some application or concepts like Voice recognition, parallel processing, quantum computation and nanotechnology are incorporated into single entity. The Generation of Computer – Which Generation is Going On?

Fix Windows could not find a driver for your network adapter error


A Computer run smoothly with the coordination of Software & Hardware. In the absence of any one it will not run at all. Software being the Master utilizes each hardware attached to the System. And each hardware is operated with the help of Device Drivers installed in it. Operating System (OS) uses these device drivers to control & utilize each hardware when needed. Each hardware connected to the system must have their own Device Driver installed. A device driver is a program to initiate a hardware when required by Operating System.




Suppose, you want your PC to connect to the Network, it can only be possible when your PC has network related Device Driver. These Device Drivers are easily downloaded from Manufacturer Websites. In this article we focus on Network related problem. Suppose, your PC not obtaining Network connectivity. And each time you are getting an error message saying "Windows could not find a d…
