Chapter 5- Visibile Networks Flashcards
Vocab
NIC
Network Interface Controller
What is the purpose of a NIC
It Identifies machines on a network, it also breaks data into frames,
Topology
Describes the ways computers conect to one another on a network (star, bus, ring, mesh)
Logical vs Physical topology
The difference between how a network is designed vs how it is actually made.
CRC
Cyclic Redundancy Check
Frame
A chunk of data shared on a network: The frame is composed of the 1-Recipeint MAC, the Senders MAC, the data being sent, and the Cyclic Redundancy Check
Ethernet
The standard for the framework of networking in the modern computer networking era
UTP
A type of cable- Unshielded Twisted Pair
Star Bus
a type of network with a central switch
Segment
the connection between a PC and the Switch
CAT 1
Standard Telephone
CAT 2
10 Mbps variant (can be used up to 100mbps)
CAT 3
Designed for 100 Mbps Networks
CAT 6
Supports 1000 Mbps Networks (in 100M segments), also supports 10mbps networks (up to 55M segments)
CAT 6a
10 Gbps for networks at 100M segments
STP
a type of cable- Shielded Twisted Pair, sheilded to protect against EM interference.
RJ-11, RJ-45
Registered Jack, The attachment used at the end of telephone wire (RJ-11), and the end of network cable segments (RJ-45)
Plenum space/cabling
The Plenum space is behind walls and celiings, it is heavier jacked (vs Standard PVC) so it doesnt burn
Network protocol software
TCP/IP
LAN
Local Area Network
WAN
Wide Area Network
TCP/IP
Transmission Control Protocol/Internet Protocol, designed by the DOD
