Q

What are/were mainframes

A

Some of the first computers which occupied the size of a room, consumed a lot of power nad created a lot of heat. They were pretty unreliable.

FORTRAN and COBOL

19
Q

What is FORTRAN

A

early high-level computer programming language

20
Q

What is COBOL?

A

COmmon Buisness-Oriented Language

21
Q

What technology did integrated circuits replace?

A

Transistors. They miniaturized them.

22
Q

What input devices did third generation computers use?

A

Keyboards and monitors

23
Q

What generation of computers did it become possible to run multiple programs at the same time?

A

Third generation of computers

24
Q

What was the computational time in third generation computers?

A

nanoseconds

25
Q

What did integrated circuits do for computers?

A

they increased computing power

26
Q

What was the technology used in fourth-generation computers and what years was it used from?

A

Microprocessors and 1971—Present)

27
Q

What is the fourth generation of computers characterized by?

A

A significant reduction in processor size (microprocessors) and a significant increase in capabilities.

28
Q

What are computer generations defined by?

A

Major technological developments that fundamentally changed the way computers operated.

29
Q

How fast could first generation computers compute?

A

Computed in milliseconds

30
Q

Why were second generation computers less prone to crashing?

A

Because the transistors generated less heat than vacuum tubes which made overheating less of a concern. This translated to components lasting longer and the system crashed less often

31
Q

What four innovations in technology are used to define the four generations of computers?

A
  1. Vacuum Tubes
  2. Transistors
  3. Integrated Circuits
  4. Microprocessors
32
Q

What technology will define the fifth generation of computers?

A

Artificial Intelligence

33
