Explanation

Optical Fiber Systems are utilized in Telecommunication Systems to transmit data as light signals through thin glass or plastic fibers.

It enabling high-speed internet, voice, and data communications over long distances.

Explanation

An IP address is a unique address that identifies a device on the internet or a local network.

IP stands for "Internet Protocol," which is the set of rules governing the format of data sent via the internet or local network.

Explanation

Derived from: computare

Means: “to calculate”, “to count”, “to sum up” or “to think together”.

Explanation

Turing's most notable work today is as a computer scientist.

In 1936, he developed the idea for the Universal Turing Machine, the basis for the first computer.

He developed a test for artificial intelligence in 1950, which is still used today.
