the whole geographical world. Types of Networks • LAN • WAN • MAN (i) LAN (Local Area Network) A local area network is a self-contained network. It lengths a small area, such as a single building, floor, or a room. In LAN, all the nodes and segments are connected directly with short range wireless technology or cables. Each computer in a LAN has its own CPU. It executes the programs. It also access the data and devices anywhere on the LAN. Through LAN many users can share expensive devices, such as

offered as WAN services over the years? (Choose two answers.) Answer: A, Switched analog circuits. B, Dedicated Digital circuits 3. This chapter claims that IP routers work well as devices that connect to many different types of interfaces, including LANs and WANs. Which of the following answers list the reasons why routers do well in this role? (Choose two answers.) Answer B. Router vendors sell many different types of physical interface cards, so the routers have the right physical connectors to

Examining Ethernet Changes through the Years ITT Technical institute, CA: IS3120 9/29/2014 The Ethernet and IEEE 802.3 CSMA/ CD LAN technologies are the most popular LAN technology in the world today. Inspired by the ALOHAnet paper written by Norman Abramson is entitled “The Aloha System – Another Alternative for Computer Communications.” It described the development of an innovative radio-based network of computers that came to be known as ALOHAnet. In 1973, Robert (Bob) Metcalfe was a recent

collection of folders in the file system that exists on each domain controller in a domain and is required for implementation of Group Policy. * The ideal environment for replication topology generation is a forest that has a forest functional level of at least Windows Server 2003. In this case, replication topology generation is faster and can accommodate more sites and domains than occurs when the forest has a forest functional level of Windows 2000. When at least one domain controller in each

Unit Five Jerrie Gomez Kaplan University Carrier Sense Multiple Access Both protocols listen for transmission, and Difference Between.com. (2011) explains that CSMA/CA is proactive, and CSMA/CD is reactive. Carrier sense multiple access/collision detection (CSMA/CD) is a protocol that deals with collisions after they occur; once a collision is identified, data transmission is stopped, and then retransmitted once listening to the network proves there is not transmitting data. Carrier sense multiple
