Describe three different types of switching fabrics commonly used in packet switches?

∙ 12y ago
a. memory
1. Packet copied by systems' CPU
2. Speed limited by memory bandwidth
b. bus
1. Datagram from input port memory to output port memory via a shared bus
2. Bus contention: switching speed limited by bus bandwidth
c. crossbar
1. Overcome bus bandwidth limitations
2. Banyan networks, other interconnection nets initially developed to connect processors in multiprocessor
3. Advanced design: fragmenting datagram into fixed length cells, switch cells through the fabric.

A lamp is to be controlled independently by switches in two different locations?
It is called three way switching.
How many 4 way switches could you put on a single light fixture?
If you are talking about intermediate switches, the switches that are in the middle of the three way (UK two way) circuit, then you can add as many as your project needs. These type of switches must be in the middle, as if installed on the end, the different position switching will not operate.
The Primary Switching Center three-position load interrupter switches provide a visible gap when open?
True
How are the three position switches of the primary switching center operated?
Just ask the dealership from where you got it. It doesn't take Einstein to figure that out.
A three way switch is what type of switch?
A three way switch is one of two devices that is used in operating a load from two different positions. This type of electrical circuit is known as three way switching. This terminology is used in North America, in Europe and the UK this type of switching is known as two way switching.

What is the advantage of switching?
you need switches to help you see. no switches can not help you see.
The primary switching center has how many Way switches?
six

What is difference between packet switching frame switching and cell switching?
Packet Switching refers to the transfering of the packet from 1 node to the other. Where as Cell Switching ,means the switching of a cell from 1 network to the other. Pls note that Packet and Cells are 2 different forms. Packet itself has header and pay load and but Packets are variable in size unlike cells which are fix. When packets are switched, the Packet Switch is used and that Switch looks for the next hop in its routing or forwarding table but when a cell is switched, ATM switches are used and the cells actually carry the data and the header and travels from 1 ATM switch to the other. The ATM switches donot use the complex method as Packet Switches use.
What is the full form of MSC in GSM?
It is mobile service switching center and not just mobile switching center. Because it does not switches our mobile, but the service.
What is meant by soft-switching operation in three-port bi-directional converter?
to prevent the switches from voltage spikes for that we using soft switching
The load interrupter switches of the primary switching center can be operated when the circuit is energized?
true
Where can Netgear switch be bought from?
You can buy a Netgear Switch online from Netgear. They have available switching solutions to fit all your needs. They have everything from Fully Managed Switches, Smart Switches and ProSafe Plus Switches and more.
Why do appliances at home have different switches?
They have different voltage. So different switches and breakers.
Why is Mercury used in light switches?
Mercury is used in switches because it is a liquid metal, conducts electricity, and is very stable. Switches made from mercury are also called "Silent Switches", since the switching occurs when the mercury makes the connection between the contacts, instead of a mechanical switch. The mercury is usually contained in a small glass vial within the switch. It is also commonly found in home thermostats, used to control heating and/or air conditioning systems.
What is the gap between two processes when the CPU executes a process and then switches into another?
CPU switching from process to another
