Essential Peripherals Flashcards
Manifests as a 9-pin, D-shell male socket
Serial Ports
Names of serial ports and connections
DB-9 and RS-232
General purpose serial interconnect for keyboards, printers, joysticks, and many other devices. Enables hot-swapping of devices
Universal Serial Bus (USB)
Integrated circuit normally built into the chipset that acts as the interface between the system and every USB device that connects to it
USB Host Controller
Part of the host controller that makes the physical connection to the USB ports
USB Root Hub
1.5 Mbps max speed for this USB standard
Low-Speed USB/USB 1.1
12 Mbps max speed for this USB standard
Full-Speed USB/USB1.1
480 Mbps max speed for this USB standard; fully backwards compatible with USB1.1
Hi-Speed USB/USB 2.0
5 Gbps max speed for this USB standard; fully backwards compatible with USB 2.0
SuperSpeed USB/USB 3.0
10 Gbps max speed for this USB standard; fully backwards compatible with USB 2.0
SuperSpeed USB 10 Gbps/USB 3.1
Adapter card that allows a motherboard to take advantage of faster speed USBs
USB Expansion Cards
Connectors that plug upstream toward the host controller (plugged into the computer)
USB A
Connectors plug downstream into USB devices
USB B
Tends to reference USB Mini-B
Mini-USB
Tends to reference USB Micro-B
Micro-USB
Reversible USB-type cable that supports up to USB 3.1 with a top speed of 10 Gbps. Quickly becoming the de facto standard port on Android devices. Thunderbolt-enabled USB C ports can reach top speeds of 40 Gbps
USB C
An open standards connector interface that is primarily used to connect peripherals to devices, including mobile devices, if they have a corresponding port
Thunderbolt
A device that extends a single USB connection to 2+ ports, almost always directly from one of the USB ports connected to the root hub
USB Hub
Interconnection standard to send wide-band signals over a serialized, physically thin connector system. Serial bus developed by Apple and Texas Instruments; enables connection of 63 devices at speeds up to 800 Mbps. Mostly supplanted by Thunderbolt
FireWire (IEEE 1394)
FireWire standard that runs at 400 Mbps
IEEE1394a
FireWire standard that runs at 800 Mbps
IEEE1394b
Runs full duplex at 10 Gbps, so it compares to USB 3.1; connects computing devices with a Mini Display Port (mDP) connector
Thunderbolt 1
Combines internal data channels, enabling throughput up to 20 Gbps; connects computing devices with a Mini Display Port (mDP) connector
Thunderbolt 2
Offers throughput up to 40 Gbps at half the power consumption of Thunderbolt 2; uses a USB C connector
Thunderbolt 3
A hardware device that most commonly enables multiple computers to be viewed and controlled by a single mouse, keyboard, and screen. Some reverse that capability, enabling a single computer to be controlled by multiple keyboards, mice, and other devices
Keyboard, Video, Mouse (KVM) Switch
Enables users to paint, ink, pencil, or otherwise draw on a computer. Received input using a special surface
Digitizer/Pen table
