Answer 1

Answer:

5)

• Tend to use specific connectivity technologies, like ethernet and token.

WANs uses technologies like Frame Relay and X.25 for connectivity for the longer distances

• LAN is a computer network that covers a small geographic area, like a home, office, or group of buildings.

WAN is a computer network that covers a broad area. For example, any network whose communications links cross-regional and metropolitan boundaries over a long distance.

• There is a need to set up a couple of extra devices on the network, so it is not very expensive.

In WAN networks as remote areas have to be connected, hence the set-up costs are higher.

• LAN has a higher data transfer rate.

WAN has a lower data transfer rate as compares to LAN.

• Ownership of LAN is private.

WAN's ownership can be private or public.

6a) DSL stands for Digital Subscriber Line. Users get a high speed bandwidth connection from a phone wall jack on an existing telephone network. DSL works within the frequencies that the telephone doesn't so you can use the Internet while making phone calls.

6e) A local area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.

b) An ISP (Internet service provider) is a company that provides individuals and other companies access to the Internet and other related services such as Web site building and virtual hosting.

f) Stands for "Metropolitan Area Network." A MAN is a network that spans a large area, such as a town or city. It is larger than a campus area network (CAN), but smaller than a wide area network (WAN). An example of a MAN is a series of wireless routers distributed across a city.

c) A modulator-demodulator, or simply a modem, is a hardware device that converts data from a digital format, intended for communication directly between devices with specialized wiring, into one suitable for a transmission medium such as telephone lines or radio.

d) The World Wide Web (WWW), commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators (URLs, such as https://example.com/ ), which may be interlinked by hypertext, and are accessible over the Internet.

7) In Client-Server Network, Centralized server is used to store the data. While in Peer-to-Peer Network, Each peer has its own data. ... In Client-Server Network, Server respond the services which is request by Client. While in Peer-to-Peer Network, Each and every node can do both request and respond for the services.

Answer 2

Answer:

LAN is ‘Local Area Network and WAN is 'Wide Area Network'. LAN covers a small area and WAN covers a large area. LAN ownership is private but WAN ownership can either be public or private.

DSL:Digital Subscriber Line

LAN: Local Area Network

ISP: Internet Service Provider

MAN: Metropolitan Area Network

Modem: Modulator-demodulator

www: World Wide Web

P2P stands for Peer-to-Peer where it does not differentiate clients and servers but Client Server Architecture does.

Explanation:

The difference between a LAN and WAN are:

• The full form of LAN is ‘Local Area Network’ but on the other hand the full form of WAN is 'Wide Area Network'.
• LAN usually covers a very small area such as home, school or office spaces whereas WAN covers a very large geographical area such as cities or countries.
• In LAN ownership is usually private but in WAN the ownership can either be public or private.

Full forms:

DSL:Digital Subscriber Line

LAN: Local Area Network

ISP: Internet Service Provider

MAN: Metropolitan Area Network

Modem: Modulator-demodulator

P2P architecture Vs Client Server Architecture:

P2P stands for Peer-to-Peer.

Peer to peer architecture does not differentiate the clients and the servers. Here every node is itself a client and a server.

But in Client Server Architecture Clients and server are different. Specific servers and clients are present.
