application software

Fill in the empty cells in this scheme

Give examples for each type of software.

of language translators: assembler, interpreter, compiler. Q3 An assembler is used

to translate assembly code into machine code. Q4 C# is translated using a compiler. Q5 The compiler reads source code and produces object code.
Application software Q6 Both types of software cost the same amount of money to develop. Bespoke software is paid for wholly by the client that requires this software. The development cost of off-the-shelf software is spread over a wide customer base, so is cheaper for an individual customer. Q7 General purpose software: spreadsheet. Special purpose software: accounting package, photo editor, presentation package. Q8 Application software is a program or series of programs that allows a user to perform non- computer tasks.
Generations of programming languages Q9 First and second generation languages are classed as low level as the instruction sets they use reflect the processor architecture. Q10 There are many types of problems to be solved by computer and different languages were developed to make it easier to solve these problems. Q11 One high-level language statement will generally be translated into several low-level language statements.
