Wired client workgroup1/29/2024 Inexpensive and easy to install and maintain. ![]() Today, Ethernet is the most popular LAN standard because it is relatively TheĮthernet standard defines guidelines for the physical configuration of the network, e.g., cabling, Must attempt to send their messages again.Įthernet is based on a bus topology, but Ethernet networks can be wired in a star pattern. If two computers onĪn Ethernet network attempt to send data at the same time, a collision occurs, and the computers Mit data when it determines the network is able to receive communications. Network (nodes) should control when data can be transmitted that is, each node attempts to trans. The following sections discuss some of the more widely used network communications standardsįor both wired and wireless networks including Ethernet, token ring, TCP/IP, 802.11 (Wi-Fi),īluetooth, UWB, IrDA, RFID, WiMAX, and WAP.Į THERNET Ethernet is a network standard that specifies no central computer or device on the Specified in a particular standard, so that their devices can communicate with the network. Hardware and software manufacturers design their products to meet the guidelines A standard that outlines characteristics of how two network devices communicate isĬalled a protocol. Speeds used on different types of networks, and the type(s) of physical cable and/or the wireless tech. The way computers access the medium to which they are attached, the type(s) of medium used, the A network standard defines guidelines that specify Propose, develop, and approve network standards. To alleviate the problems of incompatibility and ensure that hardware and software components canīe integrated into any network, various organizations such as ANSI and IEEE (pronounced I triple E) Moving data through the network from one application to another. On various types of networks to be able to communicate, the network must use similar techniques of Today’s networks connect terminals, devices, and computers from many different manufacturersĪcross many types of networks, such as wide area, local area, and wireless. Track shipped packages as the packages travel to their Their intranet to print air bills, schedule pickups, and even Shipping companies, for example, allow customers to access Sometimes a company uses an extranet, which allowsĬustomers or suppliers to access part of its intranet. Using a method similar to that used on the Internet. Tion on the intranet by creating and posting a Web page, Group scheduling, and video conferencing.Īn intranet essentially is a small version of the Internet Such as project management, chat rooms, newsgroups, Ticated uses of intranets include groupware applications Typically includes a connection to the Internet. Of organizational materials such as telephone directories,Įvent calendars, procedure manuals, employee benefits Simple intranet applications include electronic publishing Intranets generally make company informationĪccessible to employees and facilitate working in groups. Within) is an internal network that uses Internet technolo. Many organizations apply Internet and Web technologies Recognizing the efficiency and power of the Internet, Pens, the network remains inoperative until Greatest risk to a bus network is that the bus OneĪdvantage of the bus network is that comput-Įrs and other devices can be attached andĭetached at any point on the bus without dis-Īdvantage is that failure of one device usuallyĭoes not affect the rest of the bus network. They are inexpensive and easy to install. Is routed to the appropriate receiving device. Included with the transmission so that the data Mits data, the address of the receiving device is Transmits data, instructions, and information inīoth directions. The physical cable that connects the computersĪnd other devices.
