ESSENTIALS 3.15.Exam 2026 Questions
and Answers
Workstations - Correct answer-Workstations are often seriously powerful
computers that run more than one central processing unit (CPU) and whose
resources are available to other users on the network to access when needed.
Client Machine - Correct answer-A client machine is any device on the network
that can ask for access to resources from a server or powerful workstation—that for
instance, hosts a printer.
Servers - Correct answer-Servers are also powerful computers. They get their name
because they truly are "at the service" of the network and run specialized software
for the network's maintenance and
control known as the network operating system.
File server Stores and dispenses files

,Mail server The network's post office; handles email functions
Print server Manages printers on the network
Web server Manages web-based activities by running Hypertext Transfer Protocol
(HTTP) for storing web content and accessing web pages
Fax server The "memo maker" that sends and receives paperless faxes over the
network
Application server Manages network applications
Telephony server Handles the call center and call routing and can be thought of as
a
sophisticated network answering machine

,Remote access server Provides remote users with access to the network through
modems
and an IP connection
Proxy server Handles tasks in the place of other machines on the network
Host - Correct answer-The scope of possible machines and devices is so broad
because, in TCP/IP-speak, host means any network device with an IP address.
All computers connected to a network that participate directly in network
communication are classified as hosts.
Wide Area Network (WAN) - Correct answer-
Local Area Network (LAN) - Correct answer-A local area network (LAN) is
usually restricted to spanning a particular geographic location such as an office
building, a single department within a corporate office, or even a home office.
IPv4 address - Correct answer-The IPv4 address is a logical network address that
identifies a particular host. It is unique within the LAN.

, Every packet sent across the Internet has a source and destination IPv4 address
An IPv4 address is simply a series of 32 binary bits (ones and zeros).
32 bits are grouped into four 8-bit bytes called octets

11000000.10101000.00000001.00000101.
(<Network><Subnet.Mask><Host>)
We have to set up the IP address
Network Interface Card (NIC) - Correct answer-An IPv4 address is assigned to the
Network interface connection for a host. This connection is usually a network
interface card (NIC) installed in the device. Examples of end-user devices with
network interfaces include workstations, servers, network printers and IP phones.
Some servers can have more than one NIC and each of these has its own IPv4
address.
