Difference between PACKETS and FRAMES

Question

Two words commonly used in networking world - Packets and frames.

Can anyone please give the detail difference between these two words?

Hope it might sounds sill

Answer 1

Consider TCP over ATM. ATM uses 48 byte frames, but clearly TCP packets can be bigger than that. A frame is the chunk of data sent as a unit over the data link (Ethernet, ATM). A packet is the chunk of data sent as a unit over the layer above it (IP). If the data link is made specifically for IP, as Ethernet and WiFi are, these will be the same size and packets will correspond to frames.
