Origin of computer

Though he invented computers, he failed to build them. “compute” is where the word “the computer” comes from. we have heard that the COMPUTER stands for common operating machine purposely used for technological and educational research.
Growth of computer network
- A network of computers was built in the late 1950s for the U.S military radar system using the bell 101 modem. It was released by AT&T corporation in 1958. It was the first mercantile modem for computers. It is transmitted through regular telephone lines at a speed of 110 bits per second.

Now a large number of people are using 4G. In the future people will use the 5G for the next 10 years. Wi-fi will be improved to the best version of now. Artificial intelligence and machines will play an essential role in the world. Machines will be coined by machines.
Uses of computer network
