Networking and Data Transmission: Key
Concepts for IT Students
40 pin ribbon cable, connector parallel serial advanced technology attachment
to motherboard
, four octet with ranges from 0- IPv4 addresses
255
read & write times to a storage IOPS
device
used over long distances single mode-fiber
without the need for signal
repository
relationship between good SIGNAL TO NOISE RATIO (SNR)
wireless signal measurements
& unwanted noise &
interference
can identify errors or parity
corruption of data stored in
RAM
access control, content filtering, proxy server
& caching network COM
used for direct configuration of DB-9
switches, routers, & other
infrastructure devices
eight two byte groups with a IPv6
single set of double colons to
summarize zeros
T568A wire 1? white/green
T568A wire 2? green
T568A wire 3? white/orange
T568A wire 4? blue
T568A wire 5? white/blue
T568A wire 6? orange
T568A wire 7? white/brown
T568A wire 8? brown
100 Mbps, 100 m Cat5
1 Gbps, 100 m Cat5e (Enhanced)
Use: Reduces crosstalk
10 Gbps, 55 m Cat6
Use: Enterprise networks
10 Gbps, 100 m Cat6a (Augmented)
Use: Data centers, high-speed
backbones
Shielding: Always shielded Cat7
pairs (STP) Use: Not as
common, proprietary
connectors sometimes
can do 40 Gbps (shorter runs) Cat8
