几个通信英语单词细辨--transport,transmit,delivery,transfer,convey
在看英文文章时见到几个单词,想细辨一下词义:

1. transmission medium

2. delivery infrastructure, delivery system, delivery layer.
原话这么说:"This(the particular transmission medium) refers to the
lower layers of the delivery infrastructure(network layer and below) "

3. transport of data, transport layer
句子: "The transport of MPEG-4 data can occur on a variety of
delivery systems"
并且: "delivery layer" is upper than "transport layer"

4. convey
句子: convey timing and framing information

我记得很早以前老师就讲过这些词是有区别的,不知道那个同学能根据专业知识讲一下?
