Answer 1

The term computer is derived from the Latin term 'computare', this means to calculate or programmable machine. Computer can not do anything without a Program. It represents the decimal numbers through a string of binary digits. The Word 'Computer' usually refers to the Center Processor Unit plus Internal memory.

Answer 2

Here's a concise breakdown of key figures in computer history:

Charles Babbage:

Time Period: 19th century (1791-1871).

Meaning of 'computer': Initially referred to a person who computes or performs calculations.

Main contribution: Conceptualized the Analytical Engine, an early mechanical general-purpose computer.

Ada Lovelace:

Time Period: 19th century (1815-1852).

Meaning of 'computer': Initially referred to a person performing complex mathematical tasks.

Main contribution: Created the first algorithm designed to be processed by a machine, making her the first computer programmer.

Alan Turing:

Time Period: 20th century (1912-1954).

Meaning of 'computer': Evolved to represent machines performing calculations.

Main contribution: Pioneered theoretical computer science and played a vital role in breaking the Enigma code during World War II.

Mauchly and Eckert (Developers of ENIAC):

Time Period: Mid-20th century (1940s).

Meaning of 'computer': Referring to electronic devices performing complex calculations.

Main contribution: Developed ENIAC, one of the earliest electronic general-purpose computers.

ENIAC Programmers:

Time Period: Mid-20th century (1940s-1950s).

Meaning of 'computer': Initially referred to humans performing complex calculations.

Main contribution: Programmed and operated the ENIAC, contributing to early computer programming.

Grace Hopper:

Time Period: Mid-20th century (1906-1992).

Meaning of 'computer': Evolved to denote electronic machines performing computations.

Main contribution: Developed the first compiler for a programming language and popularized the idea of machine-independent programming languages.

Mark Dean:

Time Period: Late 20th century (Born 1957).

Meaning of 'computer': Referring to electronic devices for various tasks.

Main contribution: Co-invented the ISA bus and contributed significantly to the development of the personal computer.

Bonus Exhibit:

The missing individual is Konrad Zuse, a German engineer credited with creating the first functional program-controlled Turing-complete computer.
