What does CMOS

CMOS “Complementary Metal Oxide Semiconductor”.

It is also called as Non-Volatile Ram (NVRAM) or Real-Time Clock (RTC). A Complementary Metal Oxide Semiconductor is a battery powered chip that provides start up info like Hardware settings, system time & date settings etc..... to BIOS (Basic Input Output System). BIOS uses this information when you start your computer.

Generally, CMOS battery can last for ten years. But that depends on certain factors, e.g environmental factors, overheating can damage or reduce its lifetime.

A CMOS Chip has approximately 64 Bytes of memory.

Fifth Generation Computers (Present & Beyond)

Scientists are working hard on the 5th generation computers with quite a few breakthroughs. It is based on the technique of Artificial Intelligence (AI). Computers can understand spoken words & imitate human reasoning. Can respond to its surroundings using different types of sensors. Scientists are constantly working to increase the processing power of computers. They are trying to create a computer with real IQ with the help of advanced programming and technologies. IBM Watson computeris one example that outsmarts Harvard University Students. The advancement in modern technologies will revolutionize the computer in future.

Fourth Generation Computers (1975-Present)

The fourth generation computers started with the invention of Microprocessor. The Microprocessor contains thousands of ICs. Ted Hoff produced the first microprocessor in 1971 for Intel. It was known as Intel 4004. The technology of integrated circuits improved rapidly. The LSI (Large Scale Integration) circuit and VLSI (Very Large Scale Integration) circuit was designed. It greatly reduced the size of computer. The size of modern Microprocessors is usually one square inch. It can contain millions of electronic circuits. The examples of fourth generation computers are Apple Macintosh & IBM PC.

Third Generation Computers (1964-1975)

The Third generation computers used the integrated circuits (IC). Jack Kilby developed the concept of integrated circuit in 1958. It was an important invention in the computer field. The first IC was invented and used in 1961. The size of an IC is about ¼ square inch. A single IC chip may contain thousands of transistors. The computer became smaller in size, faster, more reliable and less expensive. The examples of third generation computers are IBM 370, IBM System/360, UNIVAC 1108 and UNIVAC AC 9000 etc.

Second Generation Computers (1955-1964)

The second generation computers used transistors. The scientists at Bell laboratories developed transistor in 1947. These scientists include John Barden, William Brattain and William Shockley. The size of the computers was decreased by replacing vacuum tubes with transistors. The examples of second generation computers are IBM 7094 series, IBM 1400 series and CDC 164 etc.

Advantages

Smaller in size as compared to the first generation computers.

The 2nd generation Computers were more reliable

Commercial production was difficult

Only used for specific purposes

Costly and not versatile

Puch cards were used for input.

First Generation of Computers (1942-1955)

The beginning of commercial computer age is from UNIVAC (Universal Automatic Computer). It was developed by two scientists Mauchly and Echert at the Census Department of United States in 1947. The first generation computers were used during 1942 to 1955. They were based on vacuum tubes. Examples of first generation computers are ENIVAC and UNIVAC-1.

Advantages

Vacuum tubes were the only electronic component available during those days.

Vacuum tube technology made possible to make electronic digital computers.

These computers could calculate data in millisecond.

Disadvantages

The computers were very large in size.

They consumed a large amount of energy.

They heated very soon due to thousands of vacuum tubes.

They were not very reliable.

Air conditioning was required.

Constant maintenance was required.

Non-portable.

Costly commercial production.

Limited commercial use.

Very slow speed.

Limited programming capabilities.

Used machine language only.

Used magnetic drums which provide very less data storage.

Used punch cards for input.

Not versatile and very faulty.

What is generation

The production or creation of something.

What is computer?

Computer is an electronic device that can process data at very high speed with accuracy.The first computer produced by IBM was called the PC.
