Correct Answers
network - ANS-A group of computers and other devices (such as printers) that are
connected by and can exchange data via wired or wireless transmission media.
topology - ANS-How the parts of a whole work together.
Physical topology - ANS-The physical layout of the media, nodes, and devices on a
network. A physical topology does not specify device types, connectivity methods, or
addressing schemes. A network's physical topology may differ from its logical topology
Logical topology - ANS-A characteristic of network transmission that reflects the way in
which data is transmitted between nodes, including how access to the network is
controlled and how specific resources are shared on the network. A network's logical
topology may differ from its physical topology.
NOS (network operating system) - ANS-the software that runs on a server and enables
the server to manage data, users, groups, security, applications, and other networking
functions. Popular examples of network operating systems are Windows Server, Ubuntu
Server, and Red Hat Enterprise Linux.
server operating system - ANS-An operating system designed to run on a server and
provide network services to networked clients.
P2P (peer-to-peer) network model - ANS-A network in which every computer can
communicate directly with every other computer. By default, no computer on a P2P
network has more authority than another.
scalable - ANS-The property of a network that allows the addition of nodes or increasing
its size easily.
server - ANS-Any computer or application that provides a service, such as data or other
resources, to other devices.
client-server network model - ANS-A network where resources are managed by the
NOS (network operating system) via a centralized directory database.
domain - ANS-In the context of Windows Server, a group of users, servers, and other
resources that share account and security policies.
, AD (Active Directory) - ANS-The centralized directory database that contains user
account information and security for the entire group of computers on a network.
AD DS (Active Directory Domain Services) - ANS-The Active Directory service that
manages the process allowing a user to sign on to a network from any computer on the
network and get access to the resources that Active Directory manages.
client - ANS-A computer or application that makes a request from another computer or
application.
network services - ANS-A resource the network makes available to its users, including
applications and the data provided by these applications.
client-server applications - ANS-Data or a service requested by one computer from
another.
TCP/IP suite - ANS-A suite of networking protocols that includes TCP, IP, UDP, and
many others. TCP/IP provides the foundation for data exchange across the Internet.
HTTP (Hypertext Transfer Protocol) - ANS-An application layer protocol that formulates
and interprets requests between web clients and servers.
SSL (Secure Sockets Layer) - ANS-A method of encrypting TCP/IP transmissions—
including web pages and data entered into web forms—en route between the client and
server using public key encryption technology.
TLS (Transport Layer Security) - ANS-An update to SSL (Secure Sockets Layer)
standardized by the IETF (Internet Engineering Task Force). TLS uses slightly different
encryption algorithms than SSL and is more secure, but otherwise is very similar to the
most recent version of SSL
HTTPS (HTTP Secure) - ANS-An extension to HTTP that requires data be exchanged
between client and server using SSL or TLS encryption.
SMTP (Simple Mail Transfer Protocol) - ANS-An application layer protocol responsible
for moving messages from one email server to another
POP3 (Post Office Protocol, version 3) - ANS-An application layer protocol used to
retrieve messages from a mail server. When a client retrieves mail via POP, messages
previously stored on the mail server are downloaded to the client's workstation, and
then deleted from the mail server. The most commonly used form of POP is POP3.
IMAP4 (Internet Message Access Protocol, version 4) - ANS-A mail retrieval protocol
that allows users to store messages on the mail server while reading, responding to,
and organizing the messages. The most current version of IMAP is version 4 (IMAP4).
