Study Notes
Inside the System Cabinet
- The system cabinet contains:
- Case and power supply
- Processor chip (Central Processing Unit/CPU)
- Memory chips (Random Access Memory/RAM or primary storage)
- Motherboard (system board with expansion slots)
Storage Hardware
- Storage capacity is measured in bytes
- 1 byte = 1 character of data
- 1 kilobyte = 1,024 characters
- 1 megabyte = 1,048,576 characters
- 1 gigabyte = over 1 billion characters
- 1 terabyte = over 1 trillion characters
- 1 petabyte = about 1 quadrillion characters
- Storage hardware includes hard drives, CD/DVD drives, and more
Output Hardware
- Output hardware includes:
- Video
- Sound cards
- Speakers
- Monitor
- Printer
Communications Hardware
- Communications hardware includes:
- Modem
Software
- There are two types of software:
- System software (enables computer to perform essential tasks)
- Application software (enables specific tasks and problem-solving)
- System software includes:
- Operating system (OS)
- Examples: Windows, Unix, Linux, Mac OS
- Application software is specific to the system software used
How Computers Work
- Three key concepts:
- Data is turned into information
- Hardware and software have specific functions
- All computers involve input, processing, storage, output, and communications
- Computer purposes:
- Turning data into information
- Data: raw facts and figures
- Information: data summarized or transformed for decision-making
- Hardware vs. software:
- Hardware: machinery and equipment in a computer system
- Software: electronic instructions that tell the computer how to perform a task
Basic Operations of a Computer
- Input: what goes into the computer system
- Processing: manipulation of data to turn it into information
- Storage:
- Primary storage (memory): temporary storage for data waiting to be processed
- Secondary storage (hard disk, DVDs, CDs): permanent storage
- Output: results of processing, such as on the screen, printouts, sound
- Communications: sending and receiving data
