| State one advantage of purchasing bespoke software | it is written and optimised for one client's specific needs,i.e. only has those features / functions needed.
🗑
|
||||
| State one disadvantage of purchasing bespoke software | more expensive as client has to cover production costs
🗑
|
||||
| State two advantages of writing a program in assembly language over writing a program in machine code | Easier to understand; it will take less time to code as using mnemonic operation codes
🗑
|

| What is meant by software | programs (sequences of instructions) which run on the hardware/computer
🗑
|
||||
| What is an assembler | It is a program that translates an assembly language program into machine code

| Explain what is meant by a declarative language | Class of languages including functional and logic programming languages
🗑
|
||||
| Explain what is meant by a imperative programming language | It is a language in which the instructions are executed in a programmer-defined sequence.
🗑
|
||||
| Are low-level programming languages imperative | Yes
🗑
|
||||
| Third generation programming languages are imperative, sometimes they are referred to as? | procedural languages
🗑
|
||||
| A declarative language such as Prolog and SQL | define what is to be computed rather than how the computation is to be done.
🗑
|
||||
| In declarative program you write, or declare | facts that are processed by a standard algorithm for that language to produce the desired result.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
