WGU C182 UPDATED END OF COURSE QUESTIONS AND
ANSWERS MARKED A+
✔✔Network Switch - ✔✔Like a hub, but this will only send data that is intended for a
specific computer.
✔✔Router - ✔✔Connects multiple networks together; can be used to directly connect
computers to a network; will relay messages to computers with appropriate IP
addresses
✔✔Wireless Access Point - ✔✔Can be connected to hub, switch, or router; many
routers now also act as a wireless access point; sends out a wireless signal so
computers on the network can connect without a cable
✔✔Circuit Switched Network - ✔✔Requires that a full pathway, or circuit, be est. before
transmission can begin and maintained during the entire transmission; like calling
someone on the phone
✔✔Packet Switched Network - ✔✔A message's pathway is only est. as it is sent; the
choice of pathway is based on availability and amount of message traffic
✔✔Workstations - ✔✔Creates and maintains client network connections to remote
servers
✔✔Virtual Machine (VM) - ✔✔A software emulator program that permits a computer
user to use multiple computers and multiple platforms without the expense of
purchasing multiple computers; allows a user to run software for different OS platform in
their computer that would not otherwise be able to run that software; this allows multiple
users on a network to access the software to support collaboration.
✔✔Server - ✔✔Computers that have greater hard disk storage, faster response time
and are used to respond to request from other computers on the network
✔✔Client-server Network - ✔✔Contains one or more servers; client is a computer that
will request information from another computer; server is a computer that takes requests
and responds with the requested information; the software used facilitates
communication with remote servers
✔✔File Server - ✔✔Sends files over the network at the request of clients.
Responds over LAN, within one location/site.
Support both application software and data files.
✔✔Web Server - ✔✔Stores data files (web pages) and programs (scripts).
, Responds from anywhere on the Internet.
✔✔Database Server - ✔✔Responds to queries by pulling from the database.
Typically only to local clients.
✔✔Print Server - ✔✔Monitors print jobs
✔✔Mail Server - ✔✔Two email servers communicate with each other
✔✔FTP Server - ✔✔Like web server or file server in that requests are for files and
responses are the files; data delivered between client and server.
✔✔Point-to-Point Network - ✔✔Link between two resources; links two routers without
any host or network in between
✔✔Bus Network - ✔✔Devices connected along a single cable.
Size of network is restricted.
✔✔Star Network - ✔✔Each device is connected to a central devices such as a hub or
switch.
✔✔Ring Network - ✔✔Each device is connected directly to its neighbors, and messages
are forwarded from device to device until the proper destination is reached.
✔✔Mesh Network - ✔✔Every device is connected directly to every other device in the
network.
✔✔Domain Name Server (DNS) - ✔✔Turns a user-friendly domain name, like
Google.com, into an Internet Protocol (IP) address like 70.42.251.42 that computers use
to identify each other on the network.
✔✔Parts of URL (Uniform Resource Locator) - ✔✔Protocol, Domain name,
Resource/Filename
✔✔Domain Name - ✔✔Identifies the server on which the web page can be found
✔✔Domain Name Parts - ✔✔Top level domain (TLD) name and Host name
✔✔Host Name - ✔✔Identifies the organization that is responsible for the information on
the page or provides the server space where the information is stored
