Question

Is packet is varaible length or fixed length ?

Answer 1

Depends on the packet. In general packet size is limited by an upper boundary, and some routers let you limit the packet size they will pass.

There is no rule that says all packets must be the same size.

Answer 2

Packets have a variable length but a fixed maximum size. The maximum size is dependent on your network's settings, but is usually 1500 bytes.

Answer 3

its of fixed length.

It's size can be varied depending on network conditions,for data transfer.i.e, each packet is of same size in a transfer, but the packet size is choosen according to network speed

Answer 4

Packet size is configurable and  fixed to that configured length/size.

This is done by your system administrator
