Explanation

Altair

From interest computer systems to Apple

A small organization named MITS made the primary private laptop, the Altair.

This laptop, which used Intel Corporation`s 8080 microprocessor, turned into advanced in 1974.

Explanation

The digital computer, capable of processing data in binary code (0s and 1s), was primarily developed in the USA.

John Vincent Atanasoff, an American-Bulgarian physicist, invented the first electronic digital computer in the 1930s at Iowa State College.

Explanation

The main electronic component used in first-generation counterparts was Vacuum Tubes and Valves

Leo is called the first-generation computer

First-generation (1940 - 1956)  vacuum tubes as a major piece of technology. 

The ENIAC is an example of 1st generation computer.

The time span of first-generation electronic computers was 1943 to 1959

****

Second generation (1956 - 1963) use of transistors.

Third generation (1964 - 1971)  use of Integrated circuits.

Fourth generation (1972 - 2010) use of the microprocessor

The fifth generation (2010 to present) use Artificial intelligence

Explanation

John Vincent Atanasoff invented the first digital computer in 1930. 

The inventor of the first Digital Computer belonged to the country: USA

John Vincent Atanasoff died in 1995.

Digital computer:

The Digital Computer operates on a Binary system

Explanation

DOS stands for Disk Operating System.

DOS was the Microsoft-marketed version of the first operating system (OS) to be widely installed on personal computers.

AGM 24-12-2022

Explanation

The first firm to mass-market a microcomputer as a personal computer was Radio Shaks

Release date: August 3, 1977; 45 years ago

The name is an abbreviation of Tandy Radio Shack, Z80 [microprocessor].

 It is one of the earliest mass-produced and mass-marketed retail home computers.

Explanation

The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951.

Explanation

Apple has developed a series of Macintosh operating systems.

The first versions initially had no name but came to be known as the "Macintosh System Software" in 1988, "Mac OS" in 1997 

Explanation

The main electronic component used in first-generation counterparts was Vacuum Tubes and Valves.

Leo is called the first-generation computer.

The five generations of computers:

1. First Generation (1946-1959 or 1940-1956): Vacuum tube-based technology (e.g., ENIAC).
2. Second Generation (1959-1965 or 1956-1963): Transistor-based technology.
3. Third Generation (1965-1971 or 1964-1971): Integrated circuit-based technology.
4. Fourth Generation (1972-1980): VLSI microprocessor-based technology.
5. Fifth Generation (1980-present): ULSI microprocessor-based technology, with a focus on artificial intelligence.
