Third generation computers

Third generation computers employed integrated circuits in which all the elements of an electronic circuit are contained in a tiny silicon wafer. Third generation came into existence in 1964 and was used till 1971. Third generation computers were much cheaper and more reliable than second generation of computers. They were also speedier and had vaster [...]

Super computers V/s Mainframe computers

The computer comes in many different sizes from its very beginning. Super computers are the largest and fastest computers available but very much expensive computer systems. they are used in specialized areas such as defense, aircraft design, weather research, etc. super computers mainly does the parallel processing that is one supercomputer employ so many processors [...]

Second generation computers

Second generation computers came into existence in 1956. These computers were made up of more dependable, smaller and faster transistors instead of vacuum tubes. They were smaller in size compared to first generation computers and generated lower level of heat and had greater degree of reliability that first generation. They had higher internal storage capacity [...]

Mini computers V/s micro computers

Mini computers are the type of computers which perform data processing activities in the same way as the mainframe but on a smaller scale. Data is usually input by means of a keyboard. As the name implies, a minicomputer is small computer same as microprocessor and may be called a scaled down mainframe as the [...]

Fourth generation computers

Fourth generation of computers came into existence in 1971 and is being used till date. There was primarily the advanced version of third generation computers. in third generation computers, the IC technology were mainly Medium Scale integration and Large Scale Integration but in fourth generation of computers, further developments took place and IC were Large [...]

First generation computers

There has been a continuous advancement occurred in computer systems and many generations of computers came into existence as per the advancements facilitated. The first generation computers were made of vacuum tubes and relays. They were bulky and big in size and unreliable because many vacuum tubes burned out during operations. These also generated a [...]

Fifth Generation Computers

Fifth generation computer is known as future generation of computers. This generation will be more compact and based on artificial intelligence. it is still in development and will include some new technological advancements like voice recognition, parallel processing, quantum computation, nanotechnology, and will also respond to natural human language. it is the fictional HAL9000 from [...]

Computer

Computer is an electronic device or machine which transforms raw data into a specific information or set of instructions. Computer is a machine which is used to store, process and interpret any data. the data processing include the most common cycle in which firstly, the raw data is inputted with the help of various hardware [...]

Components of computer

The main component of computer is central processing unit (CPU), also known as the processor. It is the brain of the computer. CPU’s performance is determined by the rest of computer’s circuitry and chips. It is further divided into two components called the control unit and arithmetic Logic unit. Control unit manages all the computer’s [...]

Advantages and disadvantages of computer

Computer has speed which is calculated in the smallest unit of time in human experience i.e. second. Computer does the processing with very high speed. It also facilitates accuracy. Errors do occur in computer based information systems, but precise few can be directly attributed to the computer system itself. The vast majority can be traced [...]
