Which action is taken by a Layer 2 switch when it receives a Layer 2 broadcast frame? - It sends the frame to all ports except the port on which it received the frame. A collision fragment‚ also known as a ___frame‚ is a frame of fewer than 64 bytes in length 窗体底端 - Runt On Ethernet networks‚ the hexadecimal address FF-FF-FF-FF-FF-FF represents the ___ MAC address. - broadcast What is a characteristic of a contention-based access method? - It is a nondeterministic method. Refer to the exhibit.

senders and receivers through lines of connection. Topologies are of both physical and logical aspect of the network. The physical topology describes the network’s physical wiring layout or shape. The logical topology describes the path through which the data moves. Both logical and physical topologies could be same or different in a same network. The physical and logical topologies do not have to be the same common topologies. They include a star pattern‚ ring pattern‚ and bus pattern. • Bus Topology

DATA COMMUNICATIONS & NETWORKING PROJECT II Network overhead‚ what it is? And how it’s affecting the overall performance of entire network system? SUBMITTED BY: ASM A. KARIM SPRING-2012 CIT-370-25 AS M K AR IM P AGE - 1 PENNSYLVANIA COLLEGE OF TECHNOLOGY ABSTRACT In general terms‚ overhead means anything extra that shouldn’ t be. So what is overhead in networking or how it’s affecting the entire network performance? It does not seem irrelevant for us to know something that most of

CISCO4 CHAPTER 1 WAN is a data communications network that operates beyond the geographic scope of a LAN. WAN allows the transmission of data across greater geographic distances. 3 Major characteristics of WANs • Generally connect devices that are separated by a broader geographical area than can be served by a LAN. • Use the services of carriers‚ such as telephone companies‚ cable companies‚ satellite systems‚ and network providers. • Use serial connections of

The show cdp entry command will list devices that have CDP enabled and if Layer 1 and Layer 2 are being used. The shop cdp neighbor command shows what is attached and it list the model and all software running on it. Hint: Read and study the
