Peripherals
- Peripherals are devices separate from the computer's core components (CPU, memory, power supply)
- Peripherals are categorized as input, output, and storage devices
- Peripherals connect via ports (parallel, USB, serial) and system bus interface.
Types of Peripherals (Examples)
- Input: Keyboard, Mouse, Joystick, Scanner, Web Camera, Microphone
- Output: Monitor, Printer, Speaker, Headphones, Projector
- Storage: USB Flash Drive, Memory Card, Hard Disk Drive (HDD), CD/DVD, Blue Ray, Floppy Disk, External Hard Disk
How Peripherals Work
- Peripherals operate at different speeds and use different codes, transferring varying amounts of data at different voltages
- Linking a peripheral to the processor can be a complex task.
Interfaces
- An interface is the hardware and software required to connect a processor to a peripheral.
- Interfaces compensate for differences operating characteristics between devices
- Interfaces ensure correct communication between devices.
Interface Functions
-
Buffering and Spooling: - Buffering provides temporary data storage to handle speed differences between devices and processor. - Spooling is a technique where data intended for a slow peripheral (eg. printer) is first stored on a storage device (eg. hard disk) to be transferred at a later time. This frees up the processor, allowing it to work on other tasks.
-
Data format conversion: - Processors and peripherals may format data differently - Interfaces convert between different formats (e.g., serial to parallel, analog to digital).
Serial vs. Parallel
- Parallel transmission sends multiple bits simultaneously across separate lines. This is faster over short distances.
- Serial transmission sends bits one at a time over a single line. This is more efficient for long distances.
- Differences in transfer speeds of devices and characteristics of the data requires conversions by the interface.
Analog-to-Digital Conversions
- Processors work with digital signals (binary 0s and 1s).
- Some devices send analog signals (e.g., microphone).
- Interfaces are needed to convert analog signals into digital ones for the processor to understand.
