[comp.protocols.tcp-ip] what a checksum is for

craig@NNSC.NSF.NET (Craig Partridge) (12/24/87)

I was reminded a couple of weeks ago that checksum do more than
catch corrupted bits.  They help catch some formatting errors
in headers (such as byte and bit order mistakes).

One should not dispense with transport level checksums simply because
one's media is uncorruptable.
