Network performance

Question 1

Bandwidth

Answer 1

Max rate of data transfer across a given path. Measured in bits per second. High bandwidth reduces congestion and identify threats.

Question 2

Mapping networks

Answer 2

Intermediary devices: routers, switches, and firewalls
End devices: Computers and servers that use the network

Question 3

Subnetting & collision domains

Answer 3

Subnetting: dividing network into smaller parts called subnets
Collision domains: network segment where data packets can collide if sent at same time. Reduces collision and improves network speed

Question 4

Tools for network performance

Answer 4

Ping: Tests the reachability of a host on an IP network measuring the time of message sent
Traceroute: Idenditifies the path data to reach a final destination
