Study Notes
Living in the IT Era: How Computers Work
- Decimal system: Humans use a decimal system with 10 digits (0-9) for counting and computing.
- Octal system: Uses 8 digits (0-7) and is denoted by the prefix "octa" (meaning 8).
- Hexadecimal system: Utilizes 16 digits (0-9, A-F), indicated by the prefix "hexa" (meaning 16).
- Data processing in CPU: Typed information is processed by the CPU.
- ASCII code: Information is converted into binary code (1s and 0s) using ASCII code.
- Transmission to monitor: CPU sends binary data to the computer monitor.
- Monitor displays binary data as equivalent characters, readable to humans.
- System bus: A pathway composed of cables and connectors used for communication.
- System bus carries data from peripheral devices to the CPU and main memory.
- Types of buses: Data, address, and control buses are used for communication.
- Data bus: Transfers data between the CPU and other devices.
- Address bus: Specifies the memory location for data transfer.
