First Generation (1940-1956) Vacuum Tubes

The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.
First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.
The UNIVAC and ENIAC computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951.

Second Generation (1956-1963) Transistors

Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. 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. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output.
Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN. These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology.
The first computers of this generation were developed for the atomic energy industry.

Third Generation (1964-1971) Integrated Circuits

The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.
Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.

Fourth Generation (1971-Present) Microprocessors

The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the central processing unit and memory to input/output controls—on a single chip.
In 1981 IBM introduced its first computer for the home user, and in 1984 Apple introduced the Macintosh. Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors.
As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.

Fifth Generation (Present and Beyond) Artificial Intelligence

Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.

Advantages of Computers

Because of the several computer advantages, it has become an important household item. Be it office, home, or school, it has become an indispensable device for us. A computer operated by an individual without any specific computer operator is called a personal computer (PC). A PC can be a desktop or a laptop computer, and can be used at home or at office. As per the requirement of the user, software is installed in a PC.

One can write more effectively by means of a computer. A computer allows the user to create documents, edit, print, and store them so that they can be retrieved later.

• There are tools like spelling and grammar checker, thesaurus and dictionary, installed in the computer. Thus, it takes less time to proofread a written document
• Also, there is no need to open up a dictionary book to look for meanings of words.
• Typing is much faster than writing on a paper.
• If there is a need for reorganizing the sentences or paragraphs, one can cut and paste and make the necessary changes.

Using a computer, one can remain connected to the world through the Internet. Internet is a network of computers that communicate via the Internet Protocol Suite (TCP/IP).

• The World Wide Web (WWW) or simply web is a huge resource of information that can be accessed via the Internet.
• To mention a few of the resources, there are electronic mail (e-mail), file transferring and sharing, online chat, and gaming. The Internet allows people from around the world to share knowledge, ideas, and experiences in any field.
• E-mail is a method of communication used globally, between friends, colleagues, business partners, and so on. The electronic mail is provided with a system of creating, storing, and forwarding mails.
• It may consist of text messages with attachments of audio-visual clips. One can also download or upload files using the Internet.
• There are also facilities like online chatting available on the Internet. As compared to telephonic conversation, both e-mail and online chat are cost saving.
• Online gaming is another important resource of the WWW. Many online games are available, which are of common interest for any age group.

Right from banking to investment, a user can accomplish the task by sitting within the comfort zone of his/her home.

• With this, one no longer needs to stand in the line for money withdrawing, depositing, or conducting other transactions. The same facility is available for making investments.
• In addition, one can read current news, check weather conditions, plan vacations, and make hotel and travel reservations, find out about diseases and treatment methods, learn about specific countries and their cultures, seek jobs, etc. over the Internet.
• If a computer has Internet connection facility, one can shop and that too in discounted rates. The purchased products will be delivered to the provided address, thus saving both time and money.

Nowadays, computers are widely used for education and training purposes.

• In schools, computer education has been made compulsory to spread awareness about computers. As a matter of fact, computers have become a learning tool for children.
• Indeed, a student can use the PC as a storage system for many books. Also, there are many universities that provide online degrees, which are very advantageous for those people staying in remote areas and for the disabled. In fact, online education is one of the most flexible and convenient forms of learning.
• One can take the benefit of such online degree programs staying at home without the need of relocation. Computers are also used for training purposes. Many companies use them to train their staff.
