QUESTION 2
Number 2
2ai) A data cable is a physical medium used to transfer data between devices, such as computers, printers, and external storage devices. Data cables typically consist of wires or fibers that transmit electrical signals or light pulses to carry data.
(2aii) Two types of data cables are:
- Ethernet cable: Used for wired network connections, Ethernet cables are commonly used to connect devices to a local area network (LAN) or the internet.
- USB cable: Universal Serial Bus (USB) cables are widely used for connecting peripherals such as keyboards, mice, external hard drives, and smartphones to a computer.
(2aiii) Bus speed refers to the rate at which data can be transferred between components in a computer system, such as the processor, memory, and peripherals. A higher bus speed means that data can be transferred more quickly, resulting in faster overall performance.
When the bus speed is increased, data can be transmitted more quickly between components, reducing latency and improving system responsiveness. Conversely, a slower bus speed can lead to bottlenecks and slower data transfer rates, which can impact the overall speed and performance of the system. Therefore, bus speed plays a crucial role in determining how quickly data can be processed and transferred within a computer system.
(3ai)
A file in computer terms refers to a collection of data or information that is stored under a specific name on a storage device.

(3aii)
A record is a collection of related fields that are usually treated as a single unit of information. In the context of databases, a record represents a single entry that contains multiple pieces of information about one entity.
(3aiii)
A field is a single piece of information; it is a basic element of data storage that has a specific meaning and context. Fields are used to construct records, where each field in a record typically holds one piece of information relevant to the record.
(3bi)
(i)The student’s ID number
(ii)Date of birth
(iii)Emergency contact information.
(3bii)
To edit a field in a student’s record, one would generally need to open the database application and navigate to the record in question. Next, they would locate the specific field that requires editing and enter the new information. After making the necessary changes, they would save the updated record to ensure that the edits are retained.
(3biii)
(i)Microsoft Access
(ii)MySQL.

(4ai)
A logic truth table shows all possible combinations of inputs and their corresponding outputs, illustrating the logical relationships between them.
(4aii)
(i) AND gate
(ii) OR gate
(4aiii)
| X | Y | Z = X AND Y | Z = X OR Y |
|---|---|---|---|
| 0 | 0 | 0 | 0 |
| 0 | 1 | 0 | 1 |
| 1 | 0 | 0 | 1 |
| 1 | 1 | 1 | 1 |
(4b)
A comparator is a logic device used to compare two binary numbers or signals. It typically has two input terminals for the numbers to be compared and outputs a logical indication of their relationship, such as equality, greater than, or less than. The output is determined based on the comparison of corresponding bits of the input numbers. In essence, it examines whether one input is greater than, less than, or equal to the other. Comparators are widely used in digital circuits, such as in arithmetic and logic units (ALUs), in microprocessors, and in data processing applications. They play a crucial role in tasks such as sorting, decision-making, and controlling the flow of data in electronic systems.
