Then, bridge reads the MAC address & decides whether to transmit the data to segment1 or segment2. The PC2 is accessible insegment1, so the bridge will send the data in segment1 only & eliminates all the connected PCs in segment2. In this way, the bridge reduces traffic in a computer network. hmguab https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405723850 2021-04-12 04:29:35 UTC https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405723850 Advantages hmguab https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405725085 2021-04-12 04:30:21 UTC https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405725085 • Reduces network traffic. • Prevents bandwidth waste. • Keeps a record of MAC Addresses. hmguab https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405725287 2021-04-12 04:30:28 UTC https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405725287 Disadvantages hmguab https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405726571 2021-04-12 04:31:16 UTC https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405726571 • Expensive • Slower than hubs hmguab https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405726806 2021-04-12 04:31:23 UTC https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405726806 is a network device that replicates andamplifies a received signal to anextended geographical area. hmguab https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405730010 2021-04-12 04:33:13 UTC https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405730010 Types hmguab https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405730806 2021-04-12 04:33:43 UTC https://padlet.com/hmguab/xfbjt8tyx0bhfz73/wish/1405730806 1.
