1. Communication: Networks facilitate communication through email, instant messaging, and video conferencing, allowing people to connect easily regardless of geographical distance.
2. Resource Sharing: They enable the sharing of resources such as printers, files, and internet connections, which reduces costs and improves efficiency.
3. Data Management: Networks allow for centralized data management, making it easier to back up data, maintain security, and manage user access.

Question 2: Describe the difference between hardware and software, giving two examples of each.

Answer: Hardware refers to the physical components of a computer system, which you can touch and see. Examples include:

1. Central Processing Unit (CPU): The brain of the computer that performs instructions defined by software.
2. Hard Disk Drive (HDD): A storage device used to store and retrieve digital information.

Software, on the other hand, consists of the programs and applications that run on the hardware and perform various tasks. Examples include:

1. Microsoft Office Suite: A collection of productivity software including Word, Excel, and PowerPoint.
2. Adobe Photoshop: An application used for photo editing and graphic design.

Question 3: Discuss the role of an operating system in a computer. Mention three key functions it performs.

Answer: The operating system (OS) is crucial as it manages the hardware and software resources of a computer. Key functions include:

1. Memory Management: It manages the computer’s memory, ensuring that each process and application runs smoothly without interfering with each other.
2. Process Management: The OS handles the creation, scheduling, and termination of processes, ensuring efficient execution of tasks.
3. File System Management: It manages files on various storage devices, organizing them into directories for easy navigation and access.

Answer: Cloud computing refers to the delivery of computing services, such as storage, processing power, and applications, over the internet (the cloud). Benefits for businesses include:

1. Cost Efficiency: Cloud computing reduces the need for physical hardware and maintenance costs, as resources are provided on a pay-as-you-go basis.
2. Scalability: Businesses can easily scale their operations up or down based on demand without the need for significant upfront investment in infrastructure.

Question 5: Explain what cybersecurity is and provide two measures that can be taken to enhance it.
