INTRODUCTION Computer networking is the engineering discipline concerned with the communication between computer systems or devices. A computer network is any set of computers or devices connected to each other with the ability to exchange data. It is sometimes considered a sub-discipline of telecommunications‚ computer science‚ information technology and computer engineering since it relies heavily upon the theoretical and practical application of these scientific and engineering disciplines

ISSC340 Week 7 Assignment Lesson 7 Review: LAN Standards‚ Wireless Networking and Name Resolution The purpose of this activity is to reinforce what you have learned so far about local area networks technologies. 1. Define fast Ethernet. (Minimum word count: 25) Fast Ethernet is a faster version of IEEE 802.3. It promotes the use of Ethernet at 100 Mbps using the same access method. It also can use Fast Ethernet cards that use data rates of both 10 Mbps and 100 Mbps. 2. What type of

Anderson Adam Moneypenny Why Create a VLAN Due to the changes happening within the company‚ expansion of the call center‚ employees moving around within the building‚ and employees moving off site there is a need for change to the network. Virtual Local Area Network (VLAN) is the most obvious choice because “the VLAN solution can help reduce costs by allowing us to purchase fewer router ports. It also gives us the flexibility of physically placing and moving our clients anywhere in the organization

interference and obstacles that block RF (Radio Frequency) signals. So the wireless technologies that used in LAN environment are Ethernet and Token Ring technology. Thus‚ LANs are traditionally used to connect a group of people who are in the same local area. The working groups are becoming more geographically distributed in today’s work environment. The underlying principles include the wireless environment which is an often appropriate network option that will grow and improve the demand in manufacture

Questions 7. How do local area networks (LANs) differ from metropolitan area networks (MANs)‚ wide area networks (WANs)‚ and backbone networks (BNs)? Local area networks (LANs) consist of microcomputers located in a same general area. LANs usually share circuits where computers take turns using the same circuit. In a metropolitan area networks (MANs)‚ a network usually covers a citywide area. Wide area networks (WANs) span a large geographical area. WANs span a larger area than MANs. Backbone
