CRADLEPOINT
OSI
Open Systems Interconnection. Reference model for how data
should travel between two devices on a network.
OSPF
Open Shortest Path First. A routing protocol that is used more
than RIP in larger scale networks because only changes to the
routing table are sent to all the other routers in the network as
opposed to sending the entire routing table at a regular interval,
which is how RIP functions.
Password
A sequence of characters that is used to authenticate requests to
resources on a network.
Patch
A patch is an update to a vulnerable program or system. A
common practice to keep your computer and mobile devices
secure is installing the vendor's latest patches in a timely fashion.
Some vendors release patches on a monthly or quarterly basis.
Therefore, having a computer that is unpatched for even a few
weeks could leave it vulnerable.
Personal Area Network
The interconnection of networking devices within a range of 10
meters.
Phishing
Phishing is a social engineering technique where cyber attackers
attempt to fool you into taking an action in response to an email.
Phishing was a term originally used to describe a specific attack
scenario. Attackers would send out emails pretending to be a

trusted bank or financial institution; their goal was to fool victims
into clicking on a link in the email. Once clicked, victims were
taken to a website that pretended to be the bank, but was really
created and controlled by the attacker. If the victim attempted to
log in thinking they were at their bank, their login and password
would then be stolen by the attacker. The term has evolved and
often means not just attacks designed to steal your password, but
emails designed to send you to websites that hack into your
browser or even emails with infected attachments.
Physical layer
The first layer of the OSI model. Provides the hardware means of
transmitting electrical signals on a data carrier.
Ping
A utility program that verifies that a given Internet address exists
and can receive messages. The utility sends a control packet to
the given address and waits for a response.
PoE
Power over Ethernet. The means of transmitting electricity over
the unused pairs in a category 5 Ethernet cable.
POP3
Post Office Protocol 3 is used for receiving email.
Port
A logical channel endpoint in a network. A computer might have
only one physical channel (its Ethernet channel) but can have
multiple ports (logical channels) each identified by a number.
PPP
Point-to-Point Protocol is used for two computers to communicate
with each over a serial interface, like a phone line.
