NETWORK+ Terms Q-R's

Question 1

Describes
the strategies used to manage and
increase the flow of network traffic.
QoS features enable administrators
to predict bandwidth use, monitor
that use, and control it to ensure
that bandwidth is available to the
applications that need it.

Answer 1

QoS (quality of service)

Question 2

A security
standard that employs a client/server
model to authenticate remote
network users. Remote users are authenticated using a challenge-andresponse
mechanism between the
remote-access server and the
RADIUS server.

Answer 2

RADIUS (Remote Authentication

Dial-in User Service

Question 3

A method to
store data on multiple hard drives,
enabling the overlapping of I/O
operations. The RAID levels offer
either fault-tolerance or performance
advantages.

Answer 3

RAID (Redundant Array of

Inexpensive Disks)

Question 4

A RAID configuration that
employs data striping but that lacks
redundancy because no parity information
is recorded (see RAID 5). As
a result, RAID 0 offers no fault tolerance,
but it does offer increased
performance. Requires a minimum
of two disks.

Answer 4

RAID 0

Question 5

A fault-tolerant method
that uses disk mirroring to duplicate
the information stored on a disk.
Also called disk duplexing when the
two drives in a RAID 1 array are
connected to separate disk controllers.

Answer 5

RAID 1

Question 6

A fault-tolerant method
that uses disk striping with distributed
parity. Striping is done across
the disks in blocks.

Answer 6

RAID 5

Question 7

Also called RAID 1/0. A
RAID configuration in which stripe
sets (RAID 0) are mirrored (RAID
1). This combination provides the
fault-tolerant aspects of RAID 1 and
the performance advantages of
RAID 0.

Answer 7

RAID 10

Question 8

A protocol, part of the
TCP/IP suite, that resolves MAC
addresses to IP addresses. Its relative
ARP resolves IP addresses to
MAC addresses. RARP resides on
the network layer of the OSI model.

Answer 8

RARP (Reverse Address Resolution

Protocol)

Question 9

A
Windows service that enables access
to the network through remote connections.

Answer 9

RAS (Remote Access Service)

Question 10

A
presentation layer protocol that supports
traffic between a Windows
Terminal Client and Windows
Terminal Server.

Answer 10

RDP (Remote Desktop Protocol)

Question 11

Regulations are
actual legal restrictions with legal
consequences.

Answer 11

regulations

Question 12

In networking,
having physical control of a remote
computer through software.

Answer 12

remote control

Question 13

A node or computer
connected to a network through a
remote connection. Dialing in to
the Internet from home is an example
of the remote node concept

Answer 13

remote node

Question 14

A device that regenerates
and retransmits signals on a network.
Repeaters usually are used to
strengthen signals going long distances.

Answer 14

repeater

Question 15

A system that requests
the resolution of a name to an IP
address. This term can be applied to
both DNS and WINS clients.

Answer 15

resolver

Question 16

To transfer data from
backup media to a server. The
opposite of backup.

Answer 16

restore

Question 17

The
process by which standards relating
to the Internet, the TCP/IP suite,
and associated technologies are created,
commented on, and approved

Answer 17

RFC (Request for Comments)

Question 18

Designations for the
coaxial cable used in thin coaxial
networks that operate on the
Ethernet standard.

Answer 18

RG-6/8/58/59

Question 19

An authorization provided
to users that allows them to perform
certain tasks. The network administrator
generally assigns rights.
Slightly different from but often
used with the term permissions

Answer 19

rights

Question 20

A protocol that uses hop count as a
routing metric to control the direction
and flow of packets between
routers on an internetwork.

Answer 20

RIP (Routing Information Protocol)

Question 21

A connector
used with telephone systems. Can
have up to six conductors.

Answer 21

RJ-11 connector

Question 22

A connector
used with twisted-pair cable. Can
support eight conductors for four
pairs of wires.

Answer 22

RJ-45 connector

Question 23

The entire path between

two nodes on a network.

Answer 23

route

Question 24

A device that works at the
network layer of the OSI model to
control the flow of data between
two or more network segments

Answer 24

router

Question 25

An algorithm for public-key
cryptography. Can be used for
encryption purposes. RSA is used as
a secure solution for e-commerce.

Answer 25

RSA

Question 26

Real-time Transport Protocol
(RTP). The Internet-standard protocol
for the transport of real-time
data, including audio and video.

Answer 26

RTP
