Exploring Computer Systems

What are the main components of a computer's architecture?

• Graphics card, sound card, network card

• Power supply, cooling system, case

• Operating system, software applications, drivers

• CPU, memory (RAM), storage, input devices, output devices, motherboard.

Explain the difference between RAM and ROM.

• RAM is volatile and used for temporary storage; ROM is non-volatile and used for permanent storage.

• RAM and ROM are both volatile and used for temporary storage.

• RAM is used for permanent storage; ROM is used for temporary storage.

• RAM is non-volatile and used for permanent storage; ROM is volatile and used for temporary storage.

What is the purpose of an operating system?

• To enhance graphics performance

• To serve as a database management system

• To provide internet connectivity

• The purpose of an operating system is to manage hardware and software resources and provide a user interface.

Name three popular operating systems and their primary use cases.

• 1. Windows - Personal and business computing; 2. macOS - Creative and professional work; 3. Linux - Servers and development environments.

• Unix - Personal productivity

• Android - Mobile gaming

• iOS - Web development

What is virtual memory and how does it work?

• Virtual memory is a type of physical memory that stores data permanently.

• Virtual memory is a memory management technique that allows the execution of processes that may not completely fit in physical memory by using disk space to simulate additional RAM.

• Virtual memory increases the speed of the CPU by providing more cache.

• Virtual memory is a hardware component that directly manages RAM.

Describe the function of a file system in an operating system.

• To provide internet connectivity for devices.

• To manage the graphical user interface of the operating system.

• The function of a file system is to manage data storage, organization, access, and permissions for files on a storage device.

• To control hardware components like CPU and RAM.

What are the different types of data storage solutions?

• CD/DVD

• HDD, SSD, NAS, SAN, Cloud Storage, Tape Storage, Object Storage

• External Hard Drive

• USB Flash Drive

Explain the concept of cloud storage and its advantages.

• Cloud storage is less secure than traditional storage methods.

• Cloud storage allows users to store and access data over the internet, providing advantages such as scalability, cost-effectiveness, data redundancy, accessibility, and automatic backups.

• Cloud storage is only for large businesses and not for personal use.

• Cloud storage requires physical hardware to function effectively.

What is the role of a network in computer systems?

• To increase the processing speed of a computer.

• To provide power supply to the devices.

• To store data permanently on a hard drive.

• The role of a network in computer systems is to enable communication and resource sharing between devices.

Define the term 'IP address' and its significance in networking.

• A method for encrypting data in transit.

• An IP address is a unique identifier for a device on a network, essential for routing data.

• A type of software used for network management.

• A physical cable that connects devices in a network.
