| Research and write a short report about a network
you have used. |
Report should be presented in a formal format i.e. cover,
contents, introduction, body, bibliography. Page numbers and correct margin
sizes are expected. Spelling, grammar and punctuation should be to business
standard. The use of bulleted / numbered lists is expected, and the use
of sentences, paragraphs and chapters should be the norm. The report should
identify clearly the network used and it’s location i.e. a business system,
college system or the internet etc. |
| The type of network |
The answer should be a simple statement of the network type i.e. LAN,
WAN, internet or intranet extranet. The answer should indicate the main
use(s) or users of the network, and will hopefully include an indication
of the main application software used. Answers should include details of
the number of users, details of any firewalls employed and should show an
awareness of hardware and software security employed. Some indication of
the staffing required to maintain the network may be included. |
| The data transmission standards of the network |
A specification of the various bandwidths available throughout the system
will be given i.e. modem (V series 56K), ISDN, ADSL, National Grid, Cable,
lease line. Answers will identify the data capacity of various items of
hardware such as NICs, switches/routers employed throughout the system.
Transmission methods such as Simplex, Half Duplex and Duplex should be discussed
and the features of each outlined. Answers will identify future developments
i.e. radio networks, and high-speed, wide bandwidth data communications.
|
| Outline the data transmission methods used |
Students will explain transmission methods i.e. Simplex, Half Duplex and
Full Duplex, and will outline the features of each |
| Explain modulation - demodulation |
Students will explain the modulation demodulation process and why it
is necessary. |
| Explain the significance of bandwidth |
Students will explain the significance of bandwidth in relation to the
sending or transmission of data, audio or video files, and the relationship
with speed and cost of transmission. Transmission = sending files not broadcasting
|
| Describe the applications that can be used to transmit data,
audio and video files |
Students need to research conferencing / meetings applications such as
NetMeeting, FTP and email. Other applications that can be used to send or
receive files of various types or sizes may be included. |
| Explain how you would set up and operate a modem to transmit
data and audio or video files . |
Students will explain how a modem is fitted into (or attached to) a computer.
They should describe the driver set-up process to be followed from power
up after fitting. |
| Explain how you would set up TCP/IP on a computer fitted with
a network and/or a modem |
There will be a description of how TCP/IP and/or other network protocols
relevant to the network they have experienced are implemented and configured
for this specific network situation only. (Where specific DNS settings are
used, students should detail these) |
| Describe how TCP/IP enables computer users to share files |
Students will explain the principles behind TCP/IP and how it facilitates
the transmission of data between computers. |
| Describe how applications can be shared |
Students will detail 3 different features of the conferencing application
i.e. for NetMeeting, whiteboard, chat, video Cam facilities and application
sharing. Methods of use and advantages / disadvantages will be discussed. |
| Outline internet connection options |
Answers should include reference to, and a brief description of, at least
three of the following: modems (56K, V series), ISDN, ADSL, Cable, National
Grid. Better answers will outline the specific features / data capacities
of each, the costs involved and may suggest appropriate user types for each.
