Vocabulary: Network Terms
LAN Local Area Network = a computer network that interconnects computers
within a limited area such as a residence, school, laboratory, university campus or office
building[1]and has its network equipment and interconnects locally managed. By contrast, a wide
area network (WAN), not only covers a larger geographic distance, but also generally
involvesleased telecommunication circuits or Internet links.
MAN. Metropolitan Area Network = a computer network that interconnects
users with computer resources in a geographic area or region larger than that covered by even a
large local area network (LAN) but smaller than the area covered by a wide area network (WAN).
The term is applied to the interconnection of networks in a city into a single larger network (which
may then also offer efficient connection to a wide area network). It is also used to mean the
interconnection of several local area networks by bridging them with backbone lines. The latter
usage is also sometimes referred to as a campus network.
WAN Wide Area Network =
a telecommunications network or computer
network that extends over a large geographical distance. Wide area networks are often
established with leased telecommunication circuits.
CAN.Campus Area Network = a computer network made up of an
interconnection of local area networks (LANs) within a limited geographical area.[1][2] The
networking equipments (switches, routers) and transmission media (optical fiber, copper
plant, Cat5 cabling etc.) are almost entirely owned by the campus tenant / owner: an enterprise,
university, government etc.
PAN Personal Area Network = a computer network used for data
transmission amongst devices such as computers, telephones, tablets and personal digital
assistants. PANs can be used for communication amongst the personal devices themselves
(interpersonal communication), or for connecting to a higher level network and the Internet
(an uplink) where one "master" device takes up the role as internet router.
PROTOCOL =
a system of rules that allow two or more entities of a communications
system to transmit information via any kind of variation of a physical quantity. These are the rules
or standard that defines the syntax, semantics and synchronization of communication and
possible error recovery methods. Protocols may be implemented by hardware, software, or a
combination of both.
FIREWALL =a network security system that monitors and controls the incoming and
outgoing network traffic based on predetermined security rules. A firewall typically establishes a
barrier between a trusted, secure internal network and another outside network, such as the
Internet, that is assumed not to be secure or trusted. Firewalls are often categorized as
either network firewalls or host-based firewalls. Network firewalls are a software
appliance running on general purpose hardware or hardware-based firewall computer
appliances that filter traffic between two or more networks. Host-based firewalls provide a layer
of software on one host that controls network traffic in and out of that single machine. Firewall
appliances may also offer other functionality to the internal network they protect such as acting
as a DHCP or VPN server for that network.
BANDWIDTH = the maximum data transfer rate of
a network or Internetconnection. It measures how much data can be
sent over a specific connection in a given amount of time. For
example, a gigabitEthernet connection has a bandwidth of
1,000Mbps, (125 megabytes per second). An Internet connection
via cable modem may provide 25 Mbps of bandwidth.
GATEWAY = a network point that acts as an entrance to another
network. On the Internet, anode or stopping point can be either a gateway
node or a host (end-point) node. Both the computers of Internet users and
the computers that serve pages to users are host nodes. The computers
that control traffic within your company's network or at your local Internet
service provider (ISP) are gateway nodes.
NETWORK TOPOLOGY = In communication networks, a topology is a usually
schematic description of the arrangement of a network, including its nodes and connecting lines.
There are two ways of defining network geometry: the physical topology and the logical (or signal)
topology.
BUS TOPOLOGY. = A bus topology is a network setup in
which each computer and network device are connected to a
single cable or backbone.
RING TOPOLOGY = A ring topology is a computer network
configuration where the devices are connected to each other in
a circular shape.
MESH TOPOLOGY = A network setup where each computer
and network device is interconnected with one another,
allowing for most transmissions to be distributed, even if one of
the connections go down.
TREE TOPOLOGY = A tree topology connects one star
network to other star networks.
STAR TOPOLOGY = A star topology is a topology for a Local
Area Network (LAN) in which all nodes are individually
connected to a central connection point.
SERVER = A server is an instance of a computer program that
accepts and responds to requests made by another
program(client).
ISP= Internet Service Provider: An ISP gives you an Internet
account (access to the Internet), e-mail address, web space for
a web page
.
DIRECTORY = A directory is a location for storing files on your
computer
ETHERNET = Ethernet is a fast and reliable network solution
that is still widely used today
NETWORK = A network is a collection of computers, servers ,
or other devices connected to one another allowing for data to
be shared and used
