Computer Basics Quiz

A computer is an electronic device capable of processing data, performing calculations, and executing stored instructions.

Hardware
- Central Processing Unit (CPU): The brain of the computer; executes instructions.
- Memory (RAM): Temporary storage for data and programs currently in use.
- Storage: Long-term data storage (e.g., Hard Disk Drives (HDD), Solid State Drives (SSD)).
- Input Devices: Tools for data entry (e.g., keyboard, mouse).
- Output Devices: Devices that output processed data (e.g., monitor, printer).
Software
- System Software: Includes operating systems (e.g., Windows, macOS, Linux) that manage hardware and software resources.
- Application Software: Programs designed for end-users (e.g., word processors, spreadsheets).

Personal Computers (PCs): Designed for individual use; includes desktops and laptops.
Mobile Devices: Portable computers; includes smartphones and tablets.
Servers: Powerful systems providing services and resources to other computers over a network.
Mainframes: Large, powerful computers used mainly by enterprises to process large amounts of data.
Supercomputers: Extremely powerful machines used for complex computations in fields like climate modeling and simulations.

Data Processing: Receiving data, processing it, and outputs results.
Data Storage and Retrieval: Storing information for future access.
Communication: Connecting to networks (e.g., internet) to facilitate information exchange.

Local Area Network (LAN): Connects computers in a limited area (e.g., home, office).
Wide Area Network (WAN): Covers larger geographic areas (e.g., the Internet).
Network Protocols: Rules governing data transmission (e.g., TCP/IP).

Antivirus Software: Protects against malware and viruses.
Firewalls: Monitors and controls incoming and outgoing network traffic.
Encryption: Secures data by transforming it into unreadable formats for unauthorized users.

Generations of Computers: Classified into five generations based on technological advances, from vacuum tubes to modern microprocessors.

Transforms industries through automation and data analysis.
Facilitates communication and information sharing globally.
Drives innovation in various fields, including science, education, and entertainment.
