Library resources

For task n.8. I connected into Library service then i searched for one of the core modules' courses: ' Broad band Networks'.
Firstly,I have to say that,i have a small ISP company in my country so I have experience in analogue networks such as modem based and broad band networks or ADSL .But wireless networking is new in my country.
At the beginning networking technology was not so quick and modern.It was cable networking therefor the Internet speed was very sallow.Furthermore in the cable connection it is impossible to shear the telephone line and the Internet in the same time.However, in the ADSL and Wireless even we can share several computers without cable and engaging telephone line.
I find a research article on the Internet after reading that i selected a paragraph then i copied it on the Gap maker web site for finding the academic word.In the bottom you can see the text which is about differences of cable and other access networks.At the end there is a list of academic vocabulary with their definitions.

"There are several important differences between cable and
other access networks. First, cable links typically have asym-
metric bandwidths: their downstream bandwidth is much
higher than their upstream bandwidth. Second, customers
cannot use the full raw capacity of their cable links. Instead,
cable networks use traffic shaping to restrict users from con-
suming more bandwidth than their contract stipulates. Al-
though cable networks currently allow raw data rates of up
to 40 Mbps, the contracts of individual customers specify
much lower rates, between 128 Kbps and 10 Mbps. Further,
some ISPs over-subscribe their cable access networks. In this
case, the level of service experienced by customers can vary
depending on the amount of competing network traffic.
Finally, cable modems can concatenate multiple upstream
packets into a single transmission, which results in short
bursts at high data rates. Thus, the upstream latencies can
fluctuate heavily, depending on the allocation policy, and the
amount of signaling and concatenation used by the CMTS."

Academic vocabulary:
Access: the method or way of approaching a place or person, or the right to use or look at something
Allocation:the act or process of giving out parts of a whole, or a part given out in this way
Contract:agreement,become ill,shorten:to make or become shorter or narrower, or smaller
Fluctuate:to change or vary frequently between one level or thing and another
Transmit:to send or give something
Methodology:a set of methods used in a particular area of study or activity
Protocol:e formal system of rules for correct behavior on official occasions
Validate:to make (something) officially acceptable or approved
Assumption:the act of taking control or claiming authority or an acceptance of something as true without question or proof .
