Understanding Computer Systems

What are the main components of a computer system?

• The main components of a computer system are CPU, memory (RAM), storage, and input/output devices.

• Network cables, printers, speakers, and monitors

• Operating system, antivirus software, web browser, and email client

• Motherboard, power supply, graphics card, and software

Explain the process of data processing in a computer.

• Data processing does not require feedback from the user.

• Data processing in a computer involves input, processing, storage, output, and feedback.

• Data processing only involves input and output.

• Data processing is solely about storing data without any processing.

List three examples of input devices and their functions.

• 1. Keyboard: Inputs text and commands. 2. Mouse: Controls cursor movement and selection. 3. Scanner: Converts physical documents into digital format.

• Speaker: Produces sound output.

• Projector: Displays visual content on a screen.

• Printer: Outputs text and images.

What is the purpose of output devices in a computer system?

• The purpose of output devices is to present data and information from the computer to the user.

• To process data and perform calculations.

• To connect the computer to the internet.

• To store data for future use.

Differentiate between system software and application software.

• System software manages hardware and provides a platform, while application software performs specific user tasks.

• System software is designed for mobile devices only.

• Application software manages hardware resources.

• System software is only for gaming applications.

Describe the organization of a computer system.

• Storage and network components only

• Input devices and output devices only

• A computer system is organized into CPU, memory, storage, input devices, output devices, and the motherboard.

• CPU, RAM, and software only

What are the different types of hardware components?

• Input methods, output methods, storage methods

• Processing devices, networking devices, display devices

• Input units, output units, communication devices

• Input devices, output devices, storage devices, processing units, networking components.

Explain the role of software libraries in programming.

• Software libraries complicate the coding process.

• Software libraries are irrelevant in modern programming.

• Software libraries play a crucial role in programming by providing reusable code, simplifying development, and enhancing productivity.

• Software libraries are only used for data storage.

What is mobile system organization and how does it differ from traditional systems?

• Mobile systems prioritize high processing power over battery life.

• Mobile system organization is identical to traditional systems in functionality.

• Mobile system organization emphasizes portability and energy efficiency, while traditional systems focus on performance and wired connectivity.

• Traditional systems are designed for wireless connectivity only.

Identify and describe the various types of memory in a computer.

• Primary Storage, Tertiary Storage, and Network Storage

• The various types of memory in a computer include RAM, ROM, Cache Memory, Secondary Storage, and Virtual Memory.

• Flash Memory, Hard Drive, and SSD

• Registers, L1 Cache, and L2 Cache
