used to connect one network device to other
network devices or to
connect two or more computers to share
printer , scanner etc.

-An e-mail address is used to receive e-
mail messages and is under the
nomenclature :
Nameofyourchoice @ domain.com
-website URL is an IP address
in text resolved by your DNS server and
often has nomenclature like this :
www.nameofyourchoice .com

A computer virus is a malware that, when
executed, replicates by inserting copies of
itself ( possibly modified) into
other computer programs , data files , or the
boot sector of the hard drive ; when this
replication succeeds , the affected areas are
then said to be "infected ".
2aii )
i ) Resident Viruses
ii) Multipartite Viruses
iii ) Direct Action Viruses
2b )
i ) Vulnerabilities and attacks-s a system
susceptibility
or flaw , and many vulnerabilities are
documented in the Common Vulnerabilities
and Exposures ( CVE ) database and
vulnerability management
is the cyclical practice of identifying ,
classifying, remediating , and mitigating
vulnerabilities as they are discovered .
ii) Backdoors - in a computer system , a
cryptosystem or an algorithm , is any secret
method of bypassing normal
authentication or security controls.
iii ) Denial -of- service attack -are designed to
make a machine or network resource
unavailable to its intended users.
Attackers can deny service to individual
victims , such as by deliberately entering a
wrong password enough consecutive times
to cause the victim account to be
locked, or they may overload the
capabilities of a machine or network and
block all users at once .
iv ) Eavesdropping - is the act of
surreptitiously
listening to a private conversation ,
typically between hosts on a network. For
instance, programs such as Carnivore and
NarusInsight have been used by the FBI and
NSA to eavesdrop on the systems of internet
service providers.
v) Privilege escalation-describes a situation
where an attacker with some level of
restricted access is able to , without
authorization , elevate their privileges or
access level .
