I know when I first started out in IT I didn’t realize how important knowing the small things were. If you want to do anything more than a helpdesk position it will be a fact of life you will need to know how to use things like Wireshark to truly understand how to troubleshoot the problem instead of handing it up the food chain.
What is a Frame and what does it do?
The Frame has 5 main sections. These sections allow the Ethernet Frame to:
- Sync Clocks on the talking hosts
- Specifies Sender and Receiver of a package at layer 2
- Detects errors by using CRC Checksum but does NOT correct them!
- Allows the computer to send data of flexible length
As stated a frame is made up of several parts. I’ve tried graphically displaying these parts using a mind map.
