Computer Definition
- A computer is an electronic machine that receives, processes, generates, and stores output data (information) to solve problems or perform tasks.
- Input: Data
- Process: Actions performed on the data
- Storage: Where data is kept
- Output: Information, the result of processing
Data vs. Information
-
Data: Raw, unprocessed facts and figures lacking context or meaning
- Examples: Numbers, text, images, measurements, symbols
-
Information: Data that's been processed, structured, and given meaning. It's useful for decision-making.
- Example: Average score calculated from a list of numbers
Data vs Information Example
- Data: Customer names and purchase amounts (John - 120,Mary−120, Mary - 120,Mary−80)
- Information: Total sales for the day (200)orAveragepurchasepercustomer(200) or Average purchase per customer (200)orAveragepurchasepercustomer(100)
Computer System Components
- Hardware: Physical components (tangible, mechanical, electronic)
- Examples: CPU, RAM, hard drives, input/output devices (keyboard, mouse, monitor), motherboard, network interface cards
- Software: Set of instructions, programs, and data enabling hardware to perform tasks.
- System Software: Operating System (OS), utility software, BIOS/UEFI device drivers
- Application Software: Programs for users (eg. word processing, internet browsing, games)
Data
- Includes everything from text to images to complex data like audio, video and large databases
- Can be raw (unprocessed) or processed into meaningful information, stored, and retrieved
- Examples: Documents, spreadsheets, multimedia, database records, user inputs, configurations
Users
- Individuals or entities interacting with the computer system.
- Types of users:
- End-Users: Students, office workers
- System Administrators: Manage system, hardware, software, security
- Developers: Create applications, debug, modify system behaviour
- Power Users: Specialized tasks (developers, data scientists)
Computer Hardware
- Input Units: Devices allowing users to interact and provide data/instructions for processing.
- Examples: Keyboard, mouse, scanner, microphone, camera, barcode reader
- Output Units: Devices communicating results from processing to the user.
- Examples: Monitor/display screen, printer, speakers, headphones
- System Units: Main body containing hardware for processing and data storage
- Examples: Power Supply, Motherboard, Storage Units
Power Supply
- Converts AC (alternating current) to DC (direct current) for operating the motherboard, processor, and peripheral devices.
