Explanation:
A computer keyboard is an input device that allows a person to enter letters, numbers, and other symbols (these are called characters in a keyboard) into a computer. It is one of the most used input devices for computers. Using a keyboard to enter lots of data is called typing

Answer:
The development of computers from the beginning to what we see now is called the computer generations. It is gradual advancement in the technology in the making of the computer.
Explanation:
The generation in computer technology can be defined as the development or the change in the technology in the computer as it was used. There were five generations of computer development. They were :
1. First Generation computers
In this generation, vacuum tubes was used in the circuits. It dated from 1946 to 1959.
2. Second Generation computers
These are transistors based computers. This generation ranges from 1959 to 1965.
3. Third Generation computers
This generation computers were Integrated circuit based. The generation stared in 1965 and ended in 1971.
4. Fourth Generation computers
The computers of this generation used VLSI microprocessor in the circuits. The period of the 4th generation computers are from 1971 to 1980.
5. Fifth Generation computers
The computers of this generation used ULSI microprocessor in the circuits. The 5th generation computers started from 1980s.
Answer:
Zero-day exploits
Explanation:
Zero-day exploits refers to recently found vulnerabilities in a computer software program that has been in existence but was hitherto not known and addressed by the software security experts, however, these vulnerabilities were known to hackers. While the existence of these "loop-holes" in the software can go on unnoticed for several years, hackers can take advantage of it to cause harm to the computers' programs and data.
When these attacks occur, it is called a zero-day because the attack took place on the very day that the loop-hole was discovered in the software. So exploitation has already taken place before a fix is carried out.
