hi
8 bit =1 byte
how many byte or frame=1 packet ?
thanks

Hello,
there is no relation between both (bytes and packets). A packet can be e.g. 1500 bytes (typically that is the size of an Ethernet packet), but you can also send packets of e.g. 18024 bytes, using the extended ping on a Cisco router...

To expand a little on GP's answer ... a packet can be one byte (like a Telnet packet ... one character per packet) or up to the capacity of the frame.
Using Ethernet, for example, an Ethernet frame must be at least 64 bytes ... if the packet is smaller than the payload of a minimum-sized frame, it's "padded" out to the minimum size.
The maximum size of a standard Ethernet frame is 1500 bytes; if a packet is larger than the payload capacity of the frame, the the packet is "fragmented" and sent in several frames (Gigabyte Ethernet can use "jumbo" frames to reduce protocol overhead).
The other possible complication is that encrypted packets generally don't tolerate fragmentation ... if the packet is too large for a single frame, and the "Do Not Fragment" flag is set, then the packet is dropped.
I'm not mentioning a specific payload size because Ethernet can be used to encapsulate a number of protocols (TCP/IP, IPX, DECNet, Ethertalk...) and the "packet" protocol will vary from one to the other.
FWIW
