Computer Networks Exam 100%
Correct!!
Networking - ANSWERSSharing information and resources through linked computer
systems.
Network Types - PAN (Personal Area Network) - ANSWERSA computer in the middle
and other devices (including a cell phone, tablet, wireless mouse, wireless headset, and
printer) connected to it.
Network Types - LAN (Local Area Network) - ANSWERSConsist of a collection of
computers in a single building or building complex. (e.g., A router in the middle with
various other devices such as workstations, a cell phone, a tablet, and printer
connected.)
Network Types - WAN (Wide Area Network) - ANSWERSLink systems over a greater
distance including machines on the opposite sides of the world.
TCP/IP Protocol - ANSWERSCommunication over the internet is governed by an open
collection of standards by this protocol. Anyone is free to use these protocols without
paying fees or signing license agreements.
Four Common Network Topology - ANSWERSBus, Star, Ring, and Mesh (Bus and Star
network topologies are the most common).
Network Topology - BUS - ANSWERSMachines are connected to a common
communication line. It became popular in the 1990s when it was implemented under a
set of standards/protocols known as the Ethernet.
Network Topology - Star - ANSWERSHave a single machine serving as a central point
to which all others are connected. (Various computers connected in the middle by a
router). Roots as far back as the 1970s when it evolved from the idea of a large central
computer system servicing many users at once.
In wireless networks where communication is carried out via radio broadcast to a central
machine called the access point (AP).
Network Topology - Ring - ANSWERSConnect directly to each other as a peer.
Network Topology - Mesh - ANSWERSIt connects every device in a network to every
other device; it enabled redundancy while also introducing significantly more network
traffic. Alternatively, a network could use a hybrid of these topologies.
