Question

Hi there,

Please, Need help with computer networking question. Thank You
1- In communications over a network, protocols are required. What is the framework or reference model that makes this possible?
2- What makes up this framework?
3- What company is credited with developing what is known today via IEEE 802.3 as Ethernet?-
4-What other companies joined in to promote its use and when?-
5-its initial incarnation what network topology did it employ?
6-There is another networking physical level technology trying to gain acceptance in about the same timeframe of Ethernet what is that?-
7-There are a couple of difference between this technology and Ethernet? List three?
8-Besides the cabling and computer interfaces there are several other hardware components that make up a network infrastructure. List three?
9-Describe the role of the devices you chose.
10-We discussed some basic networking equipment. What devices primarily use this layer of the OSI Stack for control and information about where to send frames?
11-Does IPX support subnetting?

Explanation / Answer

1: the Open Systems Interconnection model (OSI) is the most commonly used framework on which network protocols are based.

2: The OSI model consists of 7 layers. They are the 3 media layers, viz. Physical layer, data link layer and network layer. And the 4 Host layers, transport, session, presentation and application.

3: Xerox PARC

4: DEC, Intel and Xerox.

5: Initially, it used a star topology

6: Token Ring

7: Token ring has a 'token' passed between every two users wanting to use the network. Ethernet allows everyone to access the network at once, and takes care of a collision by resending the packet.

8: Gateways, Routers, repeaters.

9: Gateways: They are routers, that also act as proxy servers and/or firewalls.

Routers: Forward packets of data.

Repeaters: They recieve, amplify and resend a signal.

10: Could you clarify this question a bit?

11: Yes it does.
