Question

On which layer(s) we can find frames?

What are the frame transmission methods?  (List)

What is the function of SYN, STX, and ETX characters?

What is the IEEE standard number for Ethernet?

Answer 1

ANSWERS -

1) Data link layer which is layer 2 of OSI model we can find frames, it is the protocol data unit.

2) The different frame transmission methods are -

• Fixed size framing - frame size is fixed, frame length are delimiters
• Variable size framing - Size of frame varies

3) Functions of -

• SYN - Synchronous idle function is to provide signal from which synchronous correction to data terminal.
• STX - Start of text control character defines the start of text block.
• ETX - End of text character function is to inform the destination/receiving device that the end of stream has been reached in data link layer.

4) Ethernet is the technology to connect devices in LAN and WAN. The IEEE standard for Ethernet is IEEE 802.3.
