Network Topologies • LANs and WANs - Geographical coverage • LANs – A single geographical location‚ such as office building‚ school‚ etc – Typically High speed and cheaper. • WANs – Spans more than one geographical location often connecting separated LANs – Slower – Costly hardware‚ routers‚ dedicated leased lines and complicated implementation procedures. 1 Network Topologies • Topology - Physical and logical network layout – Physical – actual layout of the computer cables and other

ANSWER: In the Open Systems Interconnection (OSI) model of communication‚ the Media Access Control layer is one of two sub layers of the Data Link Control layer and is concerned with sharing the physical connection to the network among several computers. Each computer

DQ1 week 5 What is DNS? How do users benefit from it? Provide a brief description of the DNS process to resolve a URL to its IP address. Domain name systems (DNS) allows for an IP address to be assigned to a computer name or domain name. This system stores given names paired with IP addresses‚ which make identifying a computer on a network that much simpler. DNS follows an top-down heiratage‚ starting at the root on to top level‚ secondary level‚ subdomain level (optional)‚ and host level. Each

7. How do local area networks (LANs) differ from metropolitan area network (MAN)? A local area network (LAN) is a group of microcomputers located in the same general area. It covers a clearly defined small area‚ such as an office‚ home network ‚one floor or work area‚ a single building‚ or a group of buildings. While a metropolitan area network (MAN) connects LANs and BNs located in different areas to each other and to WANs. MANs typically span between three and 30 miles. For example a large university

History of LANs Data Communications began in the 1960s with an emphasis on communication over long distances — at least between different cities and often over much greater distances — but at relatively slow data transfer rates. At that time‚ that was what was needed. Most computing was done in batch mode‚ and companies needed an efficient way to transmit data processing files between computer sites. In the 1970s‚ interactive terminals began to proliferate‚ but most data communications took place

normal LAN vs. wireless LAN. Computer networks for the home and small business can be built using either wired or wireless technology. Wired Ethernet has been the traditional choice in homes‚ but Wi-Fi wireless technologies are gaining ground fast. Both wired and wireless can claim advantages over the other; both represent viable options for home and other local area networks (LANs). Below
