rather than long network addresses.
NODE TO NODE, SHORT RANGE
Broadcast Domain - Correct Answers -A broadcast domain is the portion of a network
that receives broadcast packets sent from a node in the domain.
Collision Domain - Correct Answers -A collision domain is a network segment on which
data packets may collide during transmission
URL (Uniform Resource Locator) - Correct Answers -A location or address identifying
where documents can be found on the Internet; a Web address
A URL is a reference to a web resource that specifies its location on a computer
network.
Network Nodes - Correct Answers -Networks nodes are host computers that are

Routing Hop Count - Correct Answers -The routing hop count is the total number of
routing devices a packet traverses from a source host to its final destination host.
FQDN (Fully Qualified Domain Name) - Correct Answers -the complete domain name
for a specific computer, service, or resource connected to a network.
, Hypertext Transfer Protocol (HTTP) - Correct Answers -protocol used to transfer data
between web servers and web browsers

be executed by a user or process.
Malware Types - Virus - Correct Answers -Malware that is self-replicating but must first
infect a host program and be executed by a user or process.
Advanced Malware - Obfuscation / Obfuscating Malware - Correct Answers -the action
of making something obscure, unclear, or unintelligible
