-
is the cable most commonly used in local area networks.
Twisted-pair cable
-
are the most common of all copper-based cables
Twisted-pair cables
-
This is the most common type of patch cable, and it is the type thatyou would use to connect a computer to a central connecting device like a switch.
straight through cable
-
This type is used to connect like devices to each other, for example, a computerto another computer, or a switch to another switch.
crossover cable
-
MDI
medium dependent interface
-
which tests all of the pins of a connection one by one
continuity tester
-
is anything that disrupts or modifies a signal that is traveling along a wire.
Interference
-
This is a disturbance that can affect electrical circuits, devices, and cables due to electromagnetic conduction and possibly radiation.
Electromagnetic interference (EMI)
-
This is interference that can come from AM/FM transmissions and cell phone towers.
Radio frequency interference (RFI)
-
is when the signal that is transmitted on one copper wire or pair of wires creates an undesired effect on another wire or pair of wires.
Crosstalk
-
transmits light (photons) instead of electricity, and this light is transmitted over glass or plastic.
Fiber optic cable
-
is a cable with an optical fiber that is meant to carry a single ray of light—one ray of light, one mode.
Single-mode (SM) optic
-
is a cable with a larger fiber core, capable of carrying multiple rays of light.
Multi-mode (MM) optic
-
This devicequite often also acts as a router, firewall, and IP proxy.
wireless access point (WAP)
-
allow for connectivity between a desktop computer or laptop and the wireless access point.
Wireless network adapters
-
is similar to a wireless repeater, but the bridge can connect different 802.11 standards together; this is known as bridge mode.
wireless bridge
-
is a network composed of at least one WAP and at least one computeror handheld device that can connect to the WAP.
wireless LAN (WLAN)
-
This means that wireless devices can have more antennas, up to four maximum.
Multiple-Input Multiple-Output (MIMO)
-
This is the sending of two or more frames of data in a single transmission.
Frame aggregation
-
Here, two channels that do not overlap are used together in an effort to double the physical data rate (PHY).
Channel bonding
-
is more common. It occurs when wireless clients connect to and are authenticated by a wireless access point, which can be expanded by creating a wireless distribution system—a group of WAPs interconnected wirelessly.
Infrastructure mode
-
is less common, and it is used more often in a handheld computer environment. (also referred to as peer-to-peer or P2P) networks occur when all of the clients communicate directly with each other.
Ad-hoc mode
