Appendix B Flashcards
enables transmission of data over public or private networks
Telecommunications system
a communication system created by linking two or more devices and establishing a standard methodology by which they can communcate
network
network designed to connect a group of computers in close proximity to each other
LAN
network that spans a large area such as a state, province, or country
WAN
a large computer network spanning a city
MAN
What are four things a network typically includes?
- Protocol
- Network Interface Card
- Cable
- Router
What is a network that relies on the computing network that relies on the computing power and bandwidth of the participants of the network rather than a centralized server
Peer to peer network
a computer designed to request information from a server
client
a computer dedicated to providing information in response to requests
server
a model for applications in which the bulk of back end processing , such as performing the physical search of a database, takes place on a server, while the front end processing is handled by the client
client/server network
occurs when a computer sending computer divides a message into a number of efficiently sized units of data called packets, each of which contains an address to the destination computer
packet switching
geometric arrangement of computers and other devices on the network
network topology
All devices connected to a central cable, called bus or backbone, Easy and inexpensive
Bus
All devices connected to a central device (hub), bottlenecks
Star
All devices connected to one another in the shape of a closed loop, so that each device is connected to the one on either side. Expensive and fast
Ring
Groups of star configured workstations connected to a linear bus backbone cable, combines bus and star
Hybrid
Devices are connected by signals between access points and wireless transmitters within a limited range
Wireless
a standard that specifies the format of data as well as the rules to be followed during transmission
protocol
capability of two or more computer systems to share data and resources, even though they are made by different manufacturers
interoperability
a physical and data layer technology for LAN networks, and is the most widely installed network for LAN
Ethernet
Why is Ethernet the most used LAN protocols?
Cheap
Easy
Flexible
Interoperability
transmission media manufactured so that signals are confined to a narrow path and behave predictable
wire media
type of cable composed of four or more copper wires twisted around each other
twisted wire cabling
cable that can carry a large range of signal frequencies without interference
coax
