Perfectly

wireless distribution method for two or more devices that creates a local area network using wireless frequencies

Wireless Local Area Network (WLAN)

Provisions access to configurable pools of storage devices that can be used by application servers

Storage Area Network (SAN)

Uses a centralized server or simply provides clients access to local devices like printers, file storage, or the internet

Small Office, Home Office (SoHo) LAN

a global network of appliances and personal devices that have been equipped with sensors, software, and network connectivity to report state and configuration

Internet of Things

Carries voice or data which specifies the standards a device needs to meet in order to connect to the phone or data network

Registered Jack (RJ)

RJ __ is for data networks

RJ __ is for phone networks

the theoretical measure of how much data could be transferred from a source to its destination

Bandwidth

The actual measure of how much data is successfully transferred from a source to its destination

Throughput

a designation given to a particular category that provides the ability to understand the bandwidth and the cable type to be used

Ethernet standard

Which Cat provides this? Standard = 100 Base-TX Bandwidth = 100 Mbps Distance = 100 meters

Cat 5 (Fast Ethernet)

Which Cat provides this? Standard = 1000 Base-T Bandwidth = 1000 Mbps Distance = 100 meters

Cat 5e (Gigabit Ethernet)

Which Cat provides this? Standard = 1000 Base-T Bandwidth = 1000 Mbps Distance = 100 meters Standard = 10GBase-T Bandwidth = 10 Gbps Distance = 55 meters

Cat 6

Which Cat provides this? Standard = 10GBase-T Bandwidth = 10 Gbps Distance = 100 meters

Cat 6a and Cat 7

Which Cat provides this? Standard = 40GBase-T Bandwidth = 40 Gbps Distance = 30 meters

Cat 8 (Fast Ethernet)

Contains the exact same pinouts on both ends of the cable

Straight through cable (Patch Cable)

preferred when wiring jacks inside of buildings

568b

the ability to take send and receive pins from one cable and swap those on the other end

Crossover Cable

is an automated way to electronically simulate using a crossover cable

a medium dependent interface crossover (MDIX)

a cable rating that specifies that a cable has a stronger sheathing and jacket that can withstand more extreme weather conditions

Direct Burial

a special coating put on a UTP or an STP cable that provides a fire retardant chemical layer to the outer insulating jacket are for ceilings, walls, raised floors, or air ducts

Plenum cable

the standard that's preferred when wiring jacks inside of buildings

568b

Uses light from an LED or laser to transmit info through a thing glass fiber

Fiber Optic Cable

Smaller core size, covers longer distance, and more expensive

Single Mode Fiber (SMF)

larger core size, covers shorter distances, and less expensive

Multimode Fiber (MMF)

most common, low-cost, and durable. It's also known for square connector or stick and click connector.

subscriber connector (SC)

older types of fiber connectors and to insert it into the jack and then turn half way to lock in place

Straight tip Connector (ST)

newer and smaller version of an SC connector. It's known as a love connector because they have 2 subscriber connectors together

Lucent Connector (LC)

It's very popular, smaller form factor like half the size, and fits 24 fiber reports
