A fully interconnected network was limited in this topology by using an individual cable around all nodes. Thus in this topology, only one line is shared by all nodes. Whenever any network transmits a message, it keeps both the sender address and the destination or receiver address as tags.The message ... Read More

In this topology, every node is connected using a separate physical link. Each computer network has a direct dedicated link, i.e., point to point connection with all other network computers. Each computer has its control and decision power for communication priorities.It is a very reliable topology because any transmission line’s ... Read More

There are various functions of WAN, which are as follows −Remote Data and Job EntryIt is feasible to introduce the information on the sales and transactions at the sale terminals using WANs. It is also possible to centralize this information in a computer for processing or broadcasting purposes. For example, ... Read More

There are two essential Integrated Services Digital Network (ISDN) services offered in computer network, which are as follows −Basic Rate Interface (BRI)It consists of 2B + D channels which stand for 2 Bearer medium of 64 kbps each for data and one D channel of 16 Kbps for handshaking and ...

ISDN stands for Integrated Services Digital Network. It is used to bridge the Central Office's local loop and the premise connection (home). ISDN uses the existing wiring so that no new cabling is required. It is a digital service that restores the analog plain old telephone set.An Integrated Digital Network ... Read More

RF can travel through air or space but require specific transmitting and receiving mechanisms. It has frequencies between 10 kHz to 14 kHz. In VLF (very low frequency), LF (Low Frequency), and MF (Medium Frequency) bands, radio waves follow ground waves.AM radio broadcasting uses the MF band. Radio waves in ... Read More

VSAT represents a Very Small Aperture Terminal. It is a two-way satellite ground terminal with a dish wire that is lower than 3 meters. It is generally used to transmit narrowband data (point of sale transactions such as credit card, polling) or broadband information (for the provision of satellite internet ... Read More

A wide area network is a connection of two or more computers that are geographically disappearing. It has a long-distance connection than LAN. It uses public networks like a telephone system or microwave broadcast for connection facilities.Types of WANFollowing are the types of WAN −Enterprise WAN − These computers are ... Read More

A metropolitan area network is a network that covers a larger geographic range by joining a multiple LAN to form a larger network. MAN usually connects multiple local area networks (LANs), using fiber optic cables, with a high-compact network framework. It can support uplinks to the wireless networks and the ... Read More

Following are the advantages and disadvantages of LAN −Advantages of LANThere are various advantages of LAN, which are as follows −Inexpensive transmission media.It can simplify the physical association of a device to the media.It is used to high data transmission rates.Network data transmission is independent of the connected devices rates, ...
