85. OCR 2.5 Levels of programming languages

What were early computers better described as?

• Electronic typewriters

• Electronic adding machines

• Electronic calculators

• Electronic data processors

How were early computers originally controlled?

• By a series of switches

• By a web of large electrical cables

• By punch cards

• By magnetic tapes

What was the typical duration for changing programs in early computers due to complexity?

• Every day

• Every week

• Every few weeks

• Every month

What was the purpose of permanently programmed plug boards?

• To store data

• To execute programs faster

• To hold a repertoire of commonly used instructions

• To improve memory capacity

In what form were programs typically written before the development of assembly language?

• Hexadecimal

• Binary on paper tape

• Decimal

• Octal

What is assembly language sometimes described as being close to?

• The software

• The hardware

• The user interface

• The operating system

Why were early computers forced to use hand-tuned assembly language programs?

• Due to high processing speed

• Due to limited speed and memory capacity

• Due to user demand

• Due to software limitations

What was one of the first high-level languages developed for electronic computers?

• Fortran

• COBOL

• Short code

• BASIC

What was a disadvantage of using short code?

• It was too complex to understand

• It required translation into machine code every time it ran

• It was not compatible with most computers

• It was too slow to write

What led to the growth of different high-level programming languages over the years?

• Decrease in computer size

• Increase in CPU speed and memory capacity

• Development of new hardware

• User demand for more applications
