Here are the answers to the questions: 1.i. a)* Two hardware components found inside the computer system are: Central Processing Unit (CPU)* Random Access Memory (RAM)* b) One function of the Central Processing Unit (CPU) is to execute instructions and perform calculations*. c)* Two differences between primary and secondary memories: Primary memory (e.g., RAM) is volatile, meaning it loses its data when power is off, while secondary memory (e.g., HDD, SSD) is non-volatile and retains data without power.* Primary memory is much faster to access than secondary memory.* 1.ii. a)* Two types of computer software are: System Software* Application Software* b) One example of application software used in an office for records collection is Microsoft Access* (or any other database management system). c) Utility software is a type of system software designed to help analyze, configure, optimize, or maintain a computer. An example is Antivirus software*. 1.iii. a)* Two uses of the Internet in an office environment are: Email communication* Online research and information gathering* b) One risk of using the Internet is cybersecurity threats* such as malware or phishing attacks. c)* Two Internet services are: World Wide Web (WWW)* Email* 2.i. a)* Two types of data transmission modes are: Simplex* Full-duplex* b)* Two components of a basic data communication system are: Sender* Receiver* c) One example of a transmission medium used in data communication is Fiber optic cable*. 2.ii. a) An algorithm* is a step-by-step procedure or a set of rules to be followed in calculations or other problem-solving operations, especially by a computer. b)* Flowchart to calculate the product of two numbers using successive addition: Start (Oval) Input Num1, Num2 (Parallelogram) Initialize Product = 0, Counter = 0 (Rectangle) Is Counter < Num2? (Diamond - Decision) If Yes: Product = Product + Num1 (Rectangle) If Yes: Counter = Counter + 1 (Rectangle) Loop back to "Is Counter < Num2?" If No: Output Product (Parallelogram) End (Oval) c)* Two qualities of a good algorithm are: Finiteness (it must terminate after a finite number of steps)* Definiteness (each step must be precisely defined)* 2.iii. a)* Two devices used to connect computers in a network are: Switch* Router* b) Physical topology refers to the actual layout of network cables and devices, while logical topology* describes how data flows through the network, regardless of the physical arrangement. c) One advantage of using a switch instead of a hub is that a switch sends data only to the intended recipient, reducing network traffic and improving efficiency*, whereas a hub broadcasts data to all connected devices. 3.i. a) One example of a control system used in the industry is a temperature control system in an oven*. b) The system described (water tank with automatic flow control) is a closed-loop* system. c) Feedback is important in a control system because it allows the system to monitor its output and adjust its input to maintain the desired state or achieve a specific goal*, correcting any deviations. 3.ii. a) One arithmetic operation carried out by the ALU is addition. One logical operation carried out by the ALU is AND*. b) One task performed by the ALU during data processing is comparing two numbers*. c) The results of ALU operations are stored temporarily in registers*. 3.iii. a)* Two advantages of storing student records in a database instead of paper files are: Easier and faster retrieval of information.* Reduced physical storage space and improved data security.* b) One use of a database in a school environment is managing student enrollment and academic performance records*. c) One example of software used to manage databases is MySQL*. 4.i. a) One task in industry that can be carried out using an automated system is assembly line production*. b) Automation is suitable for performing repetitive tasks because machines can perform these tasks consistently and tirelessly without human error or fatigue*, leading to higher efficiency and quality. c) One role played by sensors in an automated system is to collect data about the environment or the state of the system*, such as temperature, pressure, or position, which is then used by the control system to make decisions.
