Generation of Computers

Today we can discus about generations of computers

1st Generation Computers

UNIVAC (Universal Automatic Computer) produced in the late 50s was the first computers like ENIAC (Electronic Numerical Integrator and calculator) EDVAC (Electronic Discrete Variable Automatic Computer)

The ENIAC was an electronic vsersion of Mark I. Mechanical relays were replaced by electronic componets and were much faster than Mark I. The use of binary system and the internal storage of instruction written in digital form were the features of EDVAC. EDVAC was the first stored program electronic computer. But due to the delay in procuction, EDSAC which was built at University of Manchester in England is considered as the first stored programme electronic computer. It was in 1942.

In 1953, IBM, entered into the computer market by introducing IBM 701. By the time of IBM 650, IBM dominated the Mark by two third of it.

These are the first generation computers with vaccum tubes and stored program concept.

IInd Generation Computer (1960-64)

Introduction of the transistors (Solid State ciculatory) in place of vaccum tubes and the usage of magnitic core storage were responsible for the birth IInd generation computers

Transistor, which performs same function of a vaccum tube is similar in size, less experience generates almost no heat and also consumes only less power.

The second generatiohn computers were smaller, faster and reliable than that of first generation. They needed only little or some times no air conditioning.

The second generation also was dominated by the IBM. The most popular among them were IBM1401 (for small or medium lever business reqyurenebts) IBM 1620 (small scientific application) IBM 7000-7094 (large scale computation)

IIIrd Generation of computers (1965-70)

The evolution of IIIrd generation computers started when IBM 1360 was released on the market in 1965.

Integrated solic-state devises (ICs) improved secondary storage devises. new 1/0 devises (visual disply units, magnetic ink readers high speed printers) marked the birth of IIIrd generation computers.

Internet

Now we can discus about internet. Simply internet can be said as networking of networks. A number of servers situated in different locations all around the world controls and manages the Internet.

Most of the problems caused by mobile phones are related to the lost of secrecy and personal disintegrations. The camera phones causes several induvidual damaging incidents. The miss use of mobiles phones, camera phones, the facilities of blootuth, infrared etc are placed in the list of problems faced by the technology developments. The mobile phones with cameras were misused in taking naked and personal photos of persons. Thousand of cases were reported in this areas. The crimes and conspirasies using mobile phones are another problem. The terrorist groups and criminals uses the mobile phone in their operations.

About Computer

Today I want to say about few know things about computer

According to me computer usage is very high, Most interesting factor regarding the usage of computer is its speed & accuracy. It was 1999 I first used computer. That time i was so happy to work with computer. As computer reduces our work and reduces more work load the usage of computer is a very blessing in the office atmospheres. Computers are widely used in offices for solving the works of typing and documentations. It means the computers were widely replaced in the place of type writing machines. Usage of computer instead of type writers for preparing office letters and documentation were very amazing initially. Using the saving facility in computer the typists are very happy to change the letter details and save as into new file. As the computers are very fine in reducing work load and easy for documentation works, the short cuts and other facilities introduced by different software were another blessing for computer operators and data entry operators.

Once i used to study the shot cut keys of word processing. Later when i was attending a interview in a firm for the selection of Medical Transcriptional post, one of the member in the interview board asked about some shot cut keys for central alignment and bolding a sentence. I have really laughed silently with that question. Because he asked me that question meanwhile discussing more serious global matters. He was the technical expert in the interview board, and asked me such question aiming to shine in the interview. I answered correctly as ctrl+E and ctrl+ B. Actually I was knowing A to z keyboard shotcuts in Microsoft Office software. With my suddent answer he was really shokecd because he have never expected the answer from me. suddently he asked what is the shor cut to find a word in a word file. I replied as ctrl+F.

I have learned all the short cuts keys used in the MS Office. But after all in many interviews in which was interview board member, I have asked short cuts keys to many candidates. Many times i have expected answers for my tough questions about short cut keys about MS word. Another funny thing is that many of my friends and colleagues had commented about my way of using short cut keys while i was typing data in their presence.
