Here again we will discuss about fourth generation of computer. The time period of 4th generation of computer was ( 1971 - 1980 ). It contains very large scale integrated ( VLSI) circuits. VLSI circuit having 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of 4th generations.  Fourth generation computers became more powerful compact, reliable, and affordable.  It also give rise to personal computer revolution . In this generation time sharing , real time networs , distributed operating system were used.  All the high level language skills like C, C++, DATABASE etc were used in this generation.  It bring great development in the field of network aswellas computers became easliy available.  Maintenance costs wass lesser than the last generations. 

the fifth generation, the  VLSI technology  became ULSI  (Ultra Large Scale Integration) technology, resulting in the production of  microprocessor  chips having ten million electronic components.  This generation is based on parallel processing  hardware and AI (Artificial Intelligence) software. AL is an emerging branch in computer science which interprets the mean and method of making computer think like human beings.  All the heigh level language like c, c++, java, . Net etc are used in this generation.  It is a type of robotics and having neural network game playing.  Development of expert system to make decisions in real life situations. 

The jingling of bells and the impeccably adorable decorations at every corner of the city indicates the onset of Christmas Eve. We are going to celebrate Christmas 2019 in a few days and it is the beginning of the New Year Eve celebration. And, Santa Claus, the name that has been given to the harbinger of happiness and joy adds the special element of innocence to our life. Santa Claus brings with itself the special message of hope, happiness, joy, and merriment! He says, never let that magical element of innocence from your life. Keep the child within you always alive and make sure that you add, a little of that element in everything you are doing. From his sparkling eyes to his spectacle, snow-white beard, and unique red gown everything is probably designed to convey a message. Let's find out, how Santa Claus is the reinforcement of generosity and what message he wants to convey for living a happy and prosperous life. Messages Hidden in Every Gesture of Santa Claus!

Here we will discuss about third generation of computer.  Time period of third generation of computer was ( 1964 - 1971 ) .  The computer of third generation, used integrated circuit insted of vaccum tubes. ( ICs ) in the place of transistos.  A single IC has many transistor, resistors and capacitors along with associated circuitry.  It was more reliable in comparison to previous two generations.  The size was small comparison to first and second generations.  Required lesser maintenance.  Consume lesser electricity and generate less heat, that's why AC was not required.  It supports to heigh level language, and costly in price and fast. 

A transistor computer, now often called a second generation of computer. In this generation of computer we use discreate transistors insted  of vaccum tubes . Time period of second generation of computer was ( 1956 - 1960 ) .  It comsume less power in comparison to first generation of computer.  Cost Mantainanse of this generation of computer was heigh but in comparison to  first generation it was low   It requires AC because it producess lots of heate.  Size of this generation of computer was smaller from first generation of computer.  Accuracy was quite good in comparison to first generation of computer. 

Time period of first generation was ( 1945 - 1956 ) .  The first computer system use vaccum tubes for circuitry and magnetic drums for memory.  The UNIVAC and ENIAC computer are the example of first generation computer. It consumes high power of electricity.  Cost maintenance was so much heigh.  The speed of first generation computer was very low.  Size was very big almost it cover whole room.  The accuracy of this generation of computer was not good  

Computer is an electric device which is used to take input then process it and convert it as a output with a certain limit of time.

There are only five generations of computer.  First generation of computer.  Second generation of computer.  Third generation of computer.  Fourt generation of computer.  Fifth generation of computer.
