in the CSSA paper there was this Multy Choice involving Gateways, Routers, Switches and Bridges
The question:
19. Two LANs are connected - a ring and a bus network. The system analyst finds that both networks are using a similar protocol. Which device should the analyst use to connect the two networks?
(A) Bridge or Router
(B) Bridge or Gateway
(C) Gateway or Router
(D) File Server
The kicker?
"finds that both networks are using a similar protocol.". So you should immediately think of bridges if there are similar networks being connected.
This narrows down your choices to A or B.
(The answer, of course, is A).
You have talked about Switches, but that wasn't in the question (set of possible answers). So I am assuming that you meant to say "File Server" in answer (D).
Let's define a few things now,
Bridge - a combination of hardware and software used to link
two similar networks. So if you talk about bridges, think of networks, and think about two
similar networks.
Router - a device that determines where to send a data packet between at least two networks. This is what you want, because you have one LAN (ie a network of two topologies, refer back to the question) and you'll be transferring/sending data within and between such networks.
Gateway - a combination of hardware and software used to link two
different types of networks. As the question has stated, they are two similar networks. So you can automatically disregard answers (B) or (C), as they contain gateways.
Now, looking at the remaining answers, there is (A) - the bridge and router, and (D) - the file server.
Let's define what a file server is, just so you know.
File Server - a controlling computer in a network that stores the programs and data shared by users. This has relevance to the two networks, as they will have two networks which are (presumably) created to share files, data, applications/software and limited resources such as storage or printing facilities.
So that gets rid of (D), and you're left with (A) - the bridge and router.

But the Syllabus doesnt specify Gateways and Bridges....shud we know them?
Yes, you will need to know them (see my aforementioned definitions, above).

Jacaranda has BACKBONES....which aint in the Syllabus
I'm not a Jacaranda fan (in terms of IPT), but I am a Heinemann supporter/advocate/proponent. Jacaranda tends to waffle and beat around the bush, so they will often include things that aren't in the syllabus. You will not need to know about backbones in the HSC, IPT course (unless, of course, you are interested in reading about them or knowing about backbones and why they are so important to networks, especially in terms of the Internet).

how are ur over all views of Multy choice....i think they mainly concentrated on Core 1........n i found HSC 2002 Multi Choice easier....
I havent done the 2002 HSC paper (multiple choice) but I will have a look at that in the future most probably. Lets take a look at the breakdown in terms of the 2003 CSSA IPT trial.
Q1 Project Work (Project plans and project management)
Q2 - Project Work (Communication Skills)
Q3 - Project Work (Social/ethical issue - the changing nature of work)
Q4 - Project Work (Understanding the problem prototyping)
Q5 - Project Work (Designing solutions Design tools)
Q6 - Project Work (Designing solutions Design tools)
Q7 - Project Work (System Development Life Cycle)
Q8 - Project Work (Designing solutions Design tools)
Q9 Project Work (System Development Life Cycle)
Q10 - Information Systems and Databases (Searching)
Q11 - Information Systems and Databases (Flat file databases)
Q12 - Information Systems and Databases (Relational databases - Schemas)
Q13 Information Systems and Databases (Searching)
Q14 Information Systems and Databases (Issues relating to Information Systems - Accuracy of data)
Q15 Information Systems and Databases (Social and ethical issue Privacy Act)
Q16 Communication Systems (Speed of transmission)
Q17 Communication Systems (Error checking methods)
Q18 Communication Systems (Transmitting and Receiving transmission of data, modes of transmission)
Q19 Communication Systems (Network topologies, network hardware)
Q20 Communication Systems (Network topologies, network hardware and access methods)
They are a little bit skewed,
45% Project Work (Core 1)
30% Information Systems and Databases (Core 2)
25% Communication Systems (Core 3)

That's a very good mark. Most people in my class were getting low marks, but the top 5 or so students in my class scored within the 15, 16+ range. The highest being 18/20. I dont know what the lowest mark was, but I am assuming it is < 5.

I wont mind a mark above 80 in Trials....but im aiming for a BAND 6...
I wouldn't mind a mark like that too. I haven't received my IPT trial back, but I'm hoping for 85-90+
I am also aiming for that Band 6, not only in the trial, but in terms of the IPT course itself. I'm on track for it, but we'll wait until our trials are returned until I can confirm/reject the mark

what level was this exam./....HARDER or EASIER than the HSC??
I envisage the CSSA trials, as with every other CSSA (2003) trial to be harder than the
actual HSC examination in October/November.

i think i stuffed up Traditionsal Systems vs Electroinc communication Systems cos i wrote merely about advantages of Traditional Methods of Organising and Computerised methods of Organising ...
If the question is asking for electronic/traditional methods of COMMUNICATION, then you dont get marks for writing about traditional/electronic methods of ORGANISING data.
Non-computer and computer-based methods of organising, which I will assume you have done. This is
NOT what the question required... so if you spoke about methods of organising data (that is, Core 2: Information Systems and Databases), then you wont get any marks, because I am sure that the question was asking about Electronic/Traditional methods of COMMUNICATION (which, therefore, lies in Core 3: Communication Systems).
This was Question 24(b) sorry,
Question 24
(b) In the past, students did their research in a library or used encyclopaedias that may have had at home. Since the introduction of electronic communication, students do ost of their research on the Internet.
Discuss this issue outlining the advantages and disadvantages of electronic communication over traditional methods. 4 marks
You should have talked about things such as:
* Teleconferencing
* Telephone, fax, voice mail, electronic mail
* EFTPOS
* Electronic banking
Basically, you will need to choose one or two, (maybe three) and highlight the advantages and disadvantages of such communication systems and compare them to the traditional systems such as letters and telegrams (ie crappy methods of communication).
Things you can talk about are:
- able to send messages to more than one person
- able to send multiple messages quickly (see above)
- fast delivery
- large storage capacity
- takes less time to send something
- able to visually see/hear the person (teleconferencing and voice mail)
- transactions are faster (EFTPOS)
- saves transport costs, bills, money, etc
All you had to do was talk/write about what the advantages were, using examples of a communication system, then go on about the disadvantages and relate them back to the scenario of students doing their research at home (electronic) vs doing it at the library (traditional).
Hope this helps you out
Cheers.
I took an hour to type/think of all that! (Reading your first post asymptote, as well as your PMs and replying to both your first and second question (with multiple sub-questions) at the same time. I'm too slow, especially late at night, when my mind thinks about other things *whistles*
Good luck with it, asymptote.
