Internetworking What Is an Internetwork? An internetwork is a collection of individual networks‚ connected by intermediate networking devices‚ that functions as a single large network. Internetworking refers to the industry‚ products‚ and procedures that meet the challenge of creating and administering internetworks. History of Internetworking The first networks were time-sharing networks that used mainframes and attached terminals. Such environments were implemented by both IBM’s Systems

Q1. Compare between LAN‚ MAN and WAN? A LAN (local area network) is a group of computers and network devices connected together‚ usually within the same building. By definition‚ the connections must be high speed and relatively inexpensive (e.g.‚ token ring or Ethernet). Most Indiana University Bloomington departments are on LANs. A LAN connection is a high-speed connection to a LAN. On the IUB campus‚ most connections are either Ethernet (10 Mbps) or Fast Ethernet (100 Mbps)‚ and a few locations

Level 2 Use the OSI model to explain how an email message from you gets read by the recipient on his/her computer. a. User uses application to type email b. It travels down each layer to the physical layer and is sent via some physical media to the destination and goes back up the OSI model. Level 3 A user reports that they cannot download a file from the internet. Using the OSI model

What are open standards‚ and what‚ if any‚ are the advantages of such standards? Specifications for hardware or software that are developed by a standards organization or a consortium involved in supporting a standard. Available to the public for developing compliant products‚ open standards imply "open systems;" that an existing component in

differences between OSI and TCP/IP reference models? Explain briefly. The main differences between the two models are as follows: - - OSI is a reference model and TCP/IP is an implementation of OSI model. - TCP/IP Protocols are considered to be standards around which the Internet has developed. The OSI model however is a “Generic‚ protocol-independent standard." - TCP/IP combines the presentation and session layer issues into its application layer. - TCP/IP combines the OSI data link and

IT2301 ELECTRONIC COMMERCE UNIT – 1 INTRODUCTION Traditional Commerce and E-Commerce: Traditional Commerce: Traditional commerce perhaps started before recorded history when our ancestors first decided to specialise their everyday activities. Instead of each family unit having to grow crops‚ search for food‚ and make tools‚ families developed skills in one of these areas and traded some of their production for other needs. It started with bartering‚ which eventually gave
