QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS 100% VERIFIED
Computer Network - Correct Answer-✔✔defined as two or more computers connected together
to communicate and share resources.
Server - Correct Answer-✔✔Consider a network made up of computers like desktops, laptops,
and smartphones (called clients) that are connected to a central computer
Node - Correct Answer-✔✔Any device connected to the network that has an IP address
Network - Correct Answer-✔✔2 or more computers
Network Interface Card (NIC) - Correct Answer-✔✔is plugged into a slot on the motherboard
inside of the computer and allows a network cable to be plugged in so it can interface or
communicate with other computers.
Ethernet Card - Correct Answer-✔✔Most common NIC (UIN)
MAC (media access control) address - Correct Answer-✔✔Ethernet cards provide the computer
with a unique 48-bit address
Network Admin - Correct Answer-✔✔Business processes to become efficient/effective
Ex: large business - more people/technology - top level - assigned different going lower
level/employees
Small business - 1 person from start to finish
,Twisted Pair - Correct Answer-✔✔A twisted pair is a specialized wire that cancels out
electromagnetic interference from other electronic devices and increases reliability.
Ethernet Cable - Correct Answer-✔✔specialized wires with adapters that plug into the NIC
Network Hub - Correct Answer-✔✔a central location of the computer network that serves as a
traffic cop for network connection and communication.
Peripheal Devices - Correct Answer-✔✔Hardware such as keyboard or mouse, no IP address
Transmission Control Protocol/Internet Protocol (TCP/IP) - Correct Answer-✔✔TCP/IP checks to
see that the receiving computer accepts all of the packets that make up the spreadsheet and
that the packets are in the correct order. If not, the spreadsheet will be corrupted and not
usable for the receiving end user. TCP/IP guarantees the reliability of the computer file received
by the network's end user.
Packets - Correct Answer-✔✔spreadsheet's large file size, the network breaks the file down into
smaller, more manageable pieces
User Datagram Protocol (UDP) - Correct Answer-✔✔UDP protocols simply send the entire file at
once in a streaming fashion, it is much faster than TCP/IP. However, UDP does not guarantee a
file's reliability.
Internet - Correct Answer-✔✔- Large Vast Network
- Cables: run through ground/ocean floor
- Clinet (desktop) -> Server
- 97% of all network failures caused from human interference
- 74% of all businesses have had network outages
, Topology - Correct Answer-✔✔the mapping of a physical network and logical interconnections
between nodes
Linear Bus - Correct Answer-✔✔a network topology where each of a network's nodes is
connected to a common linear backbone that has two endpoints. Data is transmitted between
the two endpoints and the nodes are connected to the backbone. One advantage of a bus
topology is that all nodes can receive data virtually simultaneously. A disadvantage, however, is
that if the backbone is down, all nodes on the backbone are down as well.
-single wire
-all of the devices
-30 nodes or less
-two end points
-easy, cheap
Star - Correct Answer-✔✔is named for the star-shape created by nodes that radiate around a
central node in a spoke-like fashion. The center of the "star" is the hub that attaches to the
nodes with "spokes." Often, the hub is a server with networked computers and nodes as clients,
thus, a client / server model. Star topologies have similar disadvantages to the linear bus
configuration; if the central hub fails, every node attached to the hub will also fail. Star
topologies are the most common of all topologies.
-expense, efficient (Mays 2nd floor)
-easy to expand, easy to identify if a device goes down
-if switch goes down, everything goes
Ring - Correct Answer-✔✔is shaped like a ring. In this kind of topology, each computer (node) is
connected to two other computers in the network with the first and last computers being
connected to each other. Data is transmitted between computers in a circular manner. Ring
topologies are the least used topology with microcomputers. In a ring topology, if the traffic
