Question 2 Report
Which of the following is not a good ICT security policy?
Answer Details
The ICT security policy that is not good is "Re-use of old password". Reusing old passwords is not a good practice because it increases the chances of someone accessing your accounts without your permission. Hackers can obtain your old password from a previous breach and use it to gain access to your other accounts. It is essential to use strong and unique passwords for each account and not reuse old passwords. Using a password manager can help you generate and store complex passwords for each account.

Answer Details
The table above represents the Truth Table for the NAND (Not AND) logic gate. In digital electronics, a NAND gate is a logic gate which produces a high output (1) only when all inputs are low (0). It operates like an AND gate, followed by a NOT gate. The output of the NAND gate is the inverse of the AND gate. The NAND gate is widely used in digital circuits as it is a universal gate, meaning that any other logic gate can be realized using NAND gates only.
Question 24 Report
Use the following QBASIC statement to answer questions 14 and 15.
DIM DEPOSIT (1, 10) 14.
The keyword DIM in the statement stands for?
Answer Details
The keyword DIM in the QBASIC statement stands for "dimension". In programming, the DIM statement is used to declare the size of an array, which is a collection of variables of the same data type. In this case, the array is called DEPOSIT and has two dimensions: one dimension has a size of 2, and the other dimension has a size of 10. This means that the array can hold up to 20 values. So, the keyword DIM is used to specify the dimensions of an array in QBASIC, allowing the program to allocate the necessary amount of memory to store the data.
Question 25 Report
Which of the following symbols is not a relational operator in BASIC programming language?
Answer Details
The symbol that is not a relational operator in BASIC programming language is "^". Relational operators are symbols used in programming to compare values and determine whether one value is greater than, less than, equal to, or not equal to another value. In BASIC programming language, the relational operators are "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), "=" (equal to), and "<>" (not equal to). The symbol "^" is not a relational operator in BASIC programming language. It is actually an arithmetic operator used to represent exponentiation, which means raising a number to a power. For example, in BASIC, the expression "2^3" would evaluate to 8, because 2 raised to the power of 3 equals 8. So, to summarize, the symbol "^" is not a relational operator in BASIC programming language, but rather an arithmetic operator used for exponentiation.
Question 26 Report
The available page orientation in Microsoft Word are?
Answer Details
Page orientation in Microsoft Word refers to the direction in which content is printed on the page. There are two main page orientations available: portrait and landscape. Portrait orientation is the default setting, in which the page is taller than it is wide. This is the most common orientation for documents such as letters, essays, and reports. Landscape orientation, on the other hand, is where the page is wider than it is tall. This orientation is useful for documents such as spreadsheets, tables, and presentations. Therefore, the correct answer to the question is "portrait and landscape".

Which of the following factors limits access to computerized file system? it
Answer Details
The correct answer is "requires regular supply of power". A computerized file system is an electronic system that stores and organizes data on a computer. One of the key requirements for a computerized file system to function properly is a regular supply of power. Without power, the computer and its file system cannot operate, and access to the files is limited. The other options listed do not directly relate to limiting access to a computerized file system. For example, the amount of space occupied by the file system does not necessarily limit access, and a highly efficient processing system may actually enhance access to information.

Question 34 Report
The advantages of a computer include that they?
I. operate at high speeds; II. think for the user; Ill. are accurate; IV. are credible.
Answer Details
The correct option is "I, III and IV only". Computers have several advantages, but they do not "think for the user" as stated in option II. Instead, computers are designed to process and execute commands and instructions that are provided to them by users or programs. The advantages of computers include that they operate at high speeds (I), which means that they can process large amounts of data and perform complex calculations in a short period of time. They are also accurate (III), which means that they can perform tasks with a high degree of precision and consistency. Additionally, computers are credible (IV), meaning that they can provide reliable and verifiable information, which is particularly useful in fields such as scientific research and data analysis.

Which of the following statements is true for a circuit Switching communication system?
Answer Details
A dedicated channel must be established between two parties through the period of communication. In a circuit switching communication system, a dedicated physical communication path is established between the sender and the receiver for the duration of the communication session. During this time, the entire capacity of the channel is reserved for the transmission of the message, which results in a highly reliable and efficient mode of communication. However, this method of communication is not ideal for real-time communication, as the dedicated channel may remain idle during periods of silence, resulting in inefficient use of bandwidth. Therefore, this statement is false. In contrast, packet switching is more suited for real-time communication and involves breaking the message into packets that are transmitted independently and reassembled at the receiver.

Question 43 Report
The input device best used to capture finger print is?
Answer Details
The input device that is best used to capture fingerprints is option III, a fingerprint scanner. A fingerprint scanner is a device that captures the unique pattern of ridges and valleys on the surface of a person's fingertip. It works by illuminating the finger with a light source and capturing the reflection of the light through a sensor that reads the pattern of the ridges and valleys. Fingerprint scanners are widely used for security purposes, such as in biometric authentication systems for access control or identity verification. They are very accurate and reliable, and the captured fingerprints can be stored in a database for later comparison and identification. In contrast, the other options listed (I, II, and IV) are not specifically designed to capture fingerprints. Option I, a keyboard, is used for typing text, option II, a mouse, is used for pointing and clicking on a computer screen, and option IV, a microphone, is used for recording sound. While these input devices may have some limited capacity to capture fingerprints (e.g. if someone types with dirty fingers), they are not optimized for this purpose and are not as reliable or accurate as a dedicated fingerprint scanner.
Question 44 Report

Answer Details
The term that best describes a set of unorganized facts and figures is "data". Data can be defined as raw, unprocessed information that is collected and stored for later use. This information can be in any form, such as numbers, text, images, or audio. Data becomes useful when it is processed and organized into meaningful information. So, in summary, when we refer to a collection of unorganized facts and figures, we are talking about "data".
Question 45 Report
Which of the following statements can be used for looping in BASIC?
Answer Details
The statement that can be used for looping in BASIC is "FOR ... NEXT". The FOR loop is used to execute a set of statements a specified number of times, while the NEXT statement is used to terminate the FOR loop. The general format for the FOR loop is:
FOR variable = start_value TO end_value [STEP step_value]
[statements]
NEXT variable
The variable is set to the start value, and the loop executes until it reaches the end value, incrementing by the step value (if provided) each time. The statements inside the loop are executed for each iteration of the loop. The NEXT statement is used to indicate the end of the loop and to specify the variable that is being incremented.
