•What are the three functions of a layer 2 switch? •In an organization, which function do you see as most critical, and why?
There are three distinct functions of layer 2 switching 1)address learning 2)forward/filter decisions 3)loop avoidance Address learning Layer 2 switches and bridges remember the source hardware address of each frame received on an interface, [ and they enter this information into a MAC database called a forward/filter table. Forward/filter decisions When a frame is received on an
interface, the switch looks at the destination hardware address and finds the exit interface in the MAC database. The frame is only forwarded out the specified destination port. Loop avoidance If multiple connections between switches are created for redundancy purposes, network loops can occur. Spanning Tree Protocol (STP) is used to stop network loops while still permitting redundancy. ]

why are math skills important to a computer science major?
Weegy: The bottom line is very simple. If you have the math - and I'm talking diffeq and applied mechanics and dynamics - you will get jobs that others cannot. [ And strangely enough, those jobs pay very, very well. Just like everyone else says, if you're content being a web programmer at a medium- to-ok salary, then forget the math. If you want a job writing control code for F22's, at a salary that can make your head spin, then consider the ... (More)

In an organization, which function of a layer 2 switch do you see as most critical, and why?
Weegy: Layer 1, also referred to as the Physical Layer, describes the electrical interface and isn't of much interest to switch vendors. Rather it's to Layer 2 (the Data Link layer) that most switches look when deciding how to move packets around a network. [ It's here, for instance, that a switch can find the Media Access Control or MAC address of both sending and receiving devices. Layer 2 switches learn MAC addresses automatically, building ...
