Discussion: Wide Area Networks In chapter 7, we are introduced to ATM which uses a fixed length cell in transmission. Back in chapter 4, we talked about Ethernet technology, which uses a variable sized frame. Fixed Cells, like ATM Variable frames, like Ethernet On a typical freeway, cars and semi-trucks share the road. Some people leave lots of space between vehicles, and some leave very little space. Imagine a situation where a freeway only allowed cars to be a specific size, and travel a certain distance apart. Do you think this imaginary freeway would be more or less efficient? Amazon sends packages to your house with different sized boxes, depending on what is being sent. What if Amazon only had a single box size? Ethernet is very common, but there are places that ATM is used also. If you had the choice to rebuild the entire internet using only Ethernet (variable frame) or ATM (fixed cell), which would you choose, and why? To receive full credit, you must create an original post that answers the above scenario, and reply to at least one other student post with at least 50 words.
