Networking

QUESTIONS & ANSWERS:

1) What is a network?

-A network is the practice of linking two or more computing devices together for the purpose of sharing data and files.

2) What are 3 ways that networks can be classified?

-3 ways that networks can be classified are:

  • Geographic Area – LANs vs. WANs
  • Network Design – Client/Server vs. p2p
  • Network Protocol – Communication languages used by computer devices.

3) How is a p2p network different than a client server? Explain with diagram.

-A client server network is a network where multiple computers (Clients) are connected to a “Server” computer which is connected to a server database and those clients access their files/documents through that server database, while a “Peer to Peer” network is a network where each individual computer can only find their data on that computer, but can still share it to another computer in the network via downloading & uploading.

4) What is a LAN? WAN?

– A LAN is basically a network to connect “local” (or any computing device in its range) computing devices to that network.and, LAN stands for “Local Area Network”. In addition, LANs are usually used in homes, schools and or small office buildings.

-As for WAN, it is a network where computing devices may connect to and this computing devices can connect from farther ranges than a LAN. For example, WANs reach across cities, states, or even across the world. In addition, the “Internet” is the largest public server in the world.

5) What is a wireless network? 

– A wireless network is basically a network where computing devices are “wirelessly” (no wires) connected to a network. In simpler words, those computing devices are connected to a certain network without having to plug the device into any ports.

6) What is more reliable – wireless or wired network?

– Wired networks are way more reliable than wireless networks because wired networks use wires to connect a computing device which will sustain a constant signal to the network and therefore will always be connected unless the wire is unplugged or obstructed in any way. In addition to the aforementioned statement, wireless networks are less reliable because there is no constant signal due to the fact that there are electrical signals through the air and therefore some unknown disturbances like other electrical signals in the path of those signals may cause a disconnection (unlikely), or maybe just a decrease in speed; i.e. streaming, uploading, downloading, etc. Overall, unless you are “on the go” and need to connect to a network than use wireless, but if not, than it would be wise to stick to a wired connection.

7) What does a TCP/IP stand for?

– TCP stands for “Transmission Control Protocol”, while IP stands for “Internet Protocol”.
