Peripherals are devices connected externally to a computer to enhance functionality or usability.
Examples include mice, keyboards, printers, scanners, input/output devices.
Scanners, printers, and speakers are peripheral devices, as they are not central to the computer's core functions.
The CPU (Central Processing Unit) is not a peripheral device; it is integral to the computer's operation.
RAM (Random Access Memory) is also not a peripheral device, it's an essential component for the CPU and other parts of the computer to function properly.

Diagrams and images of peripherals, connectors, and cables are included in the presentation.

Various connectors and ports are used to connect peripherals and devices to computers and networks.
USB Type-C is a newer, slimmer, and more versatile version of the USB port.
USB is a commonly-used industry standard that carries data and power.
Serial ports transfer information one bit at a time, while USB ports can transfer multiple bits at once.
DVI (Digital Video Interface) and HDMI (High-Definition Multimedia Interface) are ports used for video connections. HDMI is more common in modern computers.
Audio ports are used to connect audio devices like headphones and speakers.
Common connector types illustrated include Standard USB 2.0, Mini USB 2.0, Micro USB 2.0, USB 2.0 B, and more.
Diagram of typical computer ports (like PS/2, USB, Ethernet, Microphone, Audio Out, etc.) on a motherboard is available.
