(a)(i) With the aid of a simple diagram, explain information transmission.

(ii) Give one example of information transmission.

(b) Give one example of each of the following;

(i)single user single tasking operating system.

(ii) single user multitasking operating system.

(iii) multi user operating system.

(c) List four features of a Graphical User Interface.

Answer Details

(a)(i) Information transmission refers to the process of sending and receiving information from one point to another through a communication medium. A simple diagram illustrating information transmission involves three components: the sender, the transmission medium, and the receiver. The sender encodes the information into a signal that is transmitted through the medium to the receiver, who then decodes the signal back into the original information. (ii) An example of information transmission is sending an email. The sender composes a message and sends it through the internet (the transmission medium) to the recipient, who receives the message and reads it. (b) (i) An example of a single user single tasking operating system is MS-DOS. It is a command-line based operating system that can only run one task at a time, and the user must complete that task before starting another. (ii) An example of a single user multitasking operating system is Windows. It allows the user to run multiple applications at the same time, switching between them as needed. (iii) An example of a multi-user operating system is Linux. It is designed to support multiple users simultaneously, allowing them to share system resources such as CPU, memory, and storage. (c) Four features of a Graphical User Interface (GUI) are: 1. Icons: GUIs use icons to represent files, folders, and applications, making it easy for users to navigate and find what they need. 2. Windows: GUIs use windows to display information and applications, allowing users to multitask by having multiple windows open at the same time. 3. Menus: GUIs use menus to provide access to various commands and features, making it easy for users to perform tasks without having to remember complex commands. 4. Point-and-click: GUIs allow users to interact with the system by pointing and clicking with a mouse, making it intuitive and easy to use.
