History of computer generations

History of computer generations

The starting phase of the pc wasn't so good, it wont to be very big in size, heavy and expensive. there have been many changes in its technology over time, these changes led to the birth of latest generations of computers, after every generation the scale, type and functionality of the pc was improving, then it became the pc of the time Found -

First Generation Computer

 Timeline - 1942–1955

 Vacuum tubes were utilized in this generation's computers, because of which they were very large in size and power consumption was also very high. These tubes generates lots of warmth. These computers failed to have an software, programs run in it were stored in an exceedingly punchcard. In this, the flexibility to store data was very limited. Machine language was utilized in these computers.

Second generation computer

 Timeline - 1956-1963

 within the second generation computer, the electronic device replaced the transistor. The transistors was better than the thermionic vacuum tube. during this generation, programming language was used rather than machine language in second-generation computers, although punch cards were still accustomed store data.

Third Generation Computer

 Timeline - 1964-1975

 during this generation the transistors were replaced by ICs Integrated Circuits i.e., and therefore the size of the pc became very small, the speed of those computers is decreased from micro seconds to nano seconds, which was possible by scale integrated circuits.These computers began to become small in size and cheap in cost and were easy to use yet. during this generation, high-level languages ​​Pascal and Basic were developed.

Fourth generation computers -

Timeline - 1967-1989

Microprocessors and chips started coming into fourth generation computers by which the scale of computers is extremely reduced and also the capacity is bery increased. The magnetic disc was replaced by semiconductor memory, also because the development of high-speed networks that you simply know as LANs and WANs. this is often the primary time when users were introduced to MS DOS as an software and Microsoft Windows started coming into computers after a while. because of which the practice of multimedia started. At now C language developed by dennis ritchie, which made programming easier.

Fifth generation computers -

Timeline - Since 1989 till now

Things like ULSI Ultra Large-Scale Integration, optical discs was utilized in this generation, storing more data in less space. With this, portable PCs, desktop PCs, tablets etc. revolutionized this field. Internet, email, WWW evolved. You were introduced to the new sorts of Windows, during which Windows XP can't be forgotten. Development remains occurring, the stress is on computing. for instance, you're watching Windows Cortana.
