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 .

Unbelievable
I watched a documentary film on the BBC for task n.2 .
It is unbelievable in 21st century hearing that every year nearly thousand of British girls age between 13-18 have been taken abroad for being married by force.The film coll 'This World' .A British-Pakistani woman who has born in England was presenter.
To be honest i was impressed by watching it and several times during the film i cried.It shows that how the families are forcing their daughter to being married with their cosion.The majority reasons of this kind of marriage were for getting visa.
There was a big gap of life style between their life in England and Pakistan.Most of them were living in a village with lack of technology.For example a thirteen years girl, who her given name was Tania ,was living i a Small village far from Islamabad without electricity and mobile phone. But after 2 weeks she could coll the British consul in Islamabad and tell them about her address and situation to being rescued and get back to the England.
Interestingly,the family particularly the father loves his daughter but it is a part of his cultural and after that he will be prod of his brother ism.
The British consul team was successful in rescuing three out of four girls in the film also one of the girl was rescued for second times.
To sum up,even though i come from a Asian country ,i could not believe that, in year 2008-9 forcing the teenage girls who, grow up in England, for being married in other countries without their willing.Furthermore I appreciate the British consul in Pakistan and their policy of rescuing,However, it should break privacy of the family.
