This section provides a quick preview of questions from the document. It may not display every question or the complete wording of each one. For the full content, including diagrams, tables and other information, view the original PDF above.

Q1— Section header —

1.1False If there is no JUMP instruction the program counter will INCREMENT: PC + 1

1.2False The i nstruction egister holds OP CODE as well.

1.3False The program counter holds the address of the next instruction to be carried out.

1.4True Data stored on magnetic tape is accessed (read or write\ serially in a sequential order.

1.5False The Microsoft Office uite is not open source software. You do not buy the source code when you buy Microsoft Office. Microsoft owns the source code and they do not allow end users to alter it.

1.6False The DMA controller takes over control of the processor and transfer data to and from the memory over the system bus.

1.7True The control unit and access to memory and all CPU operations are synchro nised to the system clock oscillator.

1.8False Both machine code and assembler are low level languages and are non portable.

1.9False READ reads from the RAM memory.

1.10True The accumulator stores the ongoing computational outputs from the ALU. (10 [20]20

About Logic Systems examination preparation

This TVET examination resource can be used as part of a structured revision programme. Past papers are most useful when learners attempt questions independently, work within a realistic time limit, and review their answers afterwards.

How to use this resource for revision

A TVET past examination paper is most useful when it is treated as an active revision exercise. Try the questions yourself before checking the corresponding memorandum. Where you make an error, identify the reason — was it a knowledge gap, a calculation mistake, an interpretation issue, or an examination technique problem?

For stronger examination practice, complete the paper without unnecessary interruptions and keep track of the questions that take the most time. Afterwards, review the memorandum and separate knowledge gaps from mistakes caused by interpretation, calculation, structure, or examination technique.

A practical revision approach

Start by completing the resource without looking at the memorandum. Review incorrect and incomplete answers afterwards and make a short revision list based on the areas that caused difficulty.
