Question | Answer |
network | group of computers connected by a transmission media |
stand alone computer | computer not connected to any other computer |
peer to peer network advantages | simple configuration; less expensive |
peer to peer network disadvantages | not flexible.not secure.not practical for large installations |
networks enable multiple users to | share resources and devices easily. |
networks allow you to | manage resources on multiple computers from one location |
peer to peer network | simplest form of a network |
no computer on a peer to peer network | has more authority then another |
modifying the file sharing controls via the computers operating system | common way to share resources on a peer to peer network |
P2P network | newer types of peer to peer network |
link computers from around the world to share files between each otheres hard disks | P2P networks |
server | central computer |
server | faciliate communication and resource sharing between pther computers on the network |
workstation | computer that runs a desktop operating system and connects to a network |
client/server network | the design of a network in which clients rely on servers for resource sharing and processing |
a network that uses a server to enable clients to share data,data storage space and devices | client/server network |
clients and servers communicate | through connectivity devices as switches and routers |
clients on a client server network do not share | resources directly with each other,they use the server as an intermediary |
examples of clients | personal computers,smartphones or mobile phones |
to function as a server | a computer must be running a network operating system |
computer roles | server or client |
clients | run applications and store data locally |
client server network | easier to add more computers to |
server requirements | manage data and other resources for a number of clients |
server requirements | ensure authorized user |
server requirements | control user file access |
server requirements | restrict user network access |
server requirements | supply applications to clients |
server requirements | dictates computer communication rules |
LAN | network of computers confined to a relatively small space |
LAN | building or office |
MAN | handful of government offices surrounding a capital building |
MAN | could connect multiple city government buildings around a city center |
MAN | larger then a lan connecting clinets and servers from multiple buildings |
advantages of client server networks | user credential assigned in one place |
advantages of client server networks | multiple controlled resources shared locally |
advantages of client server networks | central problem monitoring,diagnostics, |
advantages of client server networks | handle heavy processing loads |
advantages of client server networks | can connect many computers,more scalable |
WAN | a network that connects two or more geographically distinct LANs or MANs |
MAN | uses different technologies and medias than a LAN |
WAN | public universities within a state might combine and share their resources on |
WAN | Internet |
client | computer on the network requesting resources or services from another computer |
server | a computer on the network that manages shared resources |
workstation | a computer that may or may not be connected to the internet |
NIC | device inside a computer that connects a computer to the network media |
server | runs network operating software |
nic | network adapter |
nos | software that runs on a server and enables the server to manage data,users,groups,security,applications and other networking functions |
host | a computer that enables resource sharing by other computers on the same network |
node | client,server or other device that can communicates over the network and is identified by a network address |
segment | part of a network |
segment | group of nodes that uses the same communication channel for all their traffic |
backbone | router or switch |
backbone | the part of a network to which segments and devices connect |
backbone | network of networks |
protocol | standard method of communication |
packet | a distinct unit of dataexchanged between nodes on the network |
addressing | the scheme for assigning a unique identifying number to every node on the network |
transmission media | wire, cable, radio waves |
network services | functions provided by a network |
topology | physical layout of the network |
topology | star,ring,bus,hybrid |
most common topology | star |
network services | email,printer sharing,file sharing,internet access,remote access capabilities,network management |
file services | servers ability to share data files |
networks access service | allows remote users to connect to the network |
convergence | using the same network to deliver multiple types of communication services |
unified communications | centralized management of multiple network based communications |
mail services | coordinate the storage and transfer of email between users on a network |
most commonly used network service | |
functions of mail servers | intercept spam,route |
functions of mail servers | route messages according to protocols |
functions of mail servers | notify administrators or users of events, |
functions of mail servers | schedule email transmissions,retrieval,storage,maintenance |
functions of mail servers | provide a web based client for checking email |
network management services | traffic monitoring and control |
network management services | load balancing |
network management services | hardware diagnosis and failure alert |
network management services | asset management |
network management services | license tracking |
network management services | security auditing |
network management services | software distribution |
network management services | asset management |
network management services | backup and restorations of data |
traffic | the data transmission and processing activity taking place on a computer at any given time |
asset management | the process of collecting and storing data on the number and types of software and hardware assets in an organizations network |
the most popular web server software | apache |
internet services | supply web pages |
internet services | file transfer capabilities |
internet services | security filters |
internet services | means of directly logging on to other computers on the internet |
load balancing | the process of distributing data transfer activity evenly so that no device is overwhelmed |
access services | provide lan connectivity when wan connection is not cost effective |
access services | allow external users to use network resources and devices |
how networks are used | file and print services |
how networks are used | access services |
how networks are used | communication services |
how networks are used | internet services |
how networks are used | management services |
asset management software | inventory control |
software distribution | automatically transfer a file or installing an application from the server to a client on the network |
file and print services | provide the foundation for networking |
