who developed ARPANET in the 1960s.
The United States Department of Defense
what is ARPA
The Advanced Research Projects Agency Network
, ARPANET began as a network of approximately – computers.
60,000
The actual term “Internet” was finally defined in – by –
1995, FNC (The Federal Networking Council).
The procedures by which computers communicate with each other are called
protocols
the protocols initially
used by the Internet are called the
TCP/IP PROTOCOLS
Domain name system
Education - EDU
Government - GOV
Military – MIL
International – INT
Network – NET
(non-profit) Organization – ORG
Commercial - COM
a set of networking rules that enable computers to communicate
over the Internet
Internet Protocol (IP)
is simply a collection of computers or other hardware devices that are connected, either physically or logically
network
network use special hardware and software to allow them to –
information and cooperate.
exchange
is the term that describes the processes involved in designing, implementing,
upgrading, managing and otherwise working with networks and network technologies
networking
is the most common kind of network set up
LAN or Local Area Network
A local area network, or LAN, is a network of connected computers in a room, building, or set
of buildings. This is also called as –
intranets
is a computer network that connects number of
LANs to form larger network, so that the computer resources can be shared
MAN stands for Metropolitan Area Network.
MAN is specially designed to provide – to the users in which the speed ranges in terms of Mbps
high-speed connectivity
is a communications network that makes use of existing technology to connect local computer networks into a larger working network
that may cover both national and international locations.
The wide area network, often referred to as a WAN
The concept of a wide area network as a means of taking individual location-based computer
networks and using them to create a – for the entire corporation
means that employees can work from just about anywhere.
unified computer network
is the schematic description of a network arrangement, connecting various nodes(sender and receiver) through lines of connection
Network Topology
is a network type in which every computer and network device is connected to single cable. When it has exactly two endpoints.
Bus topology
it forms a ring as each computer is connected to another computer, with the last one connected to the first. Exactly two neighbors for each device
- Ring Topology
in this type of topology all the computers are connected to a single hub
through a cable. This hub is the central node and all point-to-point nodes are connected to the
central node.
Star Topology
It is a point-to-point connection to other nodes or devices. All the network nodes are connected to each other
Mesh Topology
It has a root node, and all other nodes are connected to it forming a
hierarchy. It is also called hierarchical topology It should at least have three levels to the
hierarchy
- Tree Topology
It is a hardware
component used to connect a computer with another computer
onto a network.
