Some Simple Networking Questions

Hi friends,
I had a phone-interview and i was asked some  basic networking questions(win xp/2000),i would be obliged if you can kindly answer them:

1.You are at the client's workstation--modem,network adapter,cabling,internet connection wizard (eg username,password etc) and power connections are all working fine.But the internet is not working.Whats steps would you take?

2.192.x.x.x is a address on a public or a private network?

3.Name 3-4 wireless standards(i guess,the need some IEEE standards here)?

4.What type of cable would you use to transfer a bandwidth of 100Mbps.

5.I didnt understood this question,but see guys if you understand.The modem is connected to the internet(or might be he said to your computer) in which topology?

See guys,if you can help me with these.I would also like to know of some good online networking links if you  know some....to just prepare myself for the written exam.

Cheers!!!

I'll be happy to answer them.  What's the company you're interviewing for?

I would suggest you get a copy of Exam Cram's Network+ book - it will teach you about networking.  If you can't answer these questions yourself, I don't see how you'll get or keep the job if they are looking for someone with networking skills - even basic ones.

I am sorry..i wont like to disclose the company if that goes fine with you guys.
Secondly,dont worry about my prospects of getting or keeping the job.I have a bachelor's degree in computer sc. and i just need to refresh my brains and remove the programming rust ...to get back on track....
thanks anywayz.

See, these look like homework questions.  And again, I would be happy to answer them - for the company, I'm always looking for new clients.  IMHO, Questions 1-4 are BEYOND easy and most people without a computer science degree could guess them.

If you want, post what YOU would do and I'll have you understand why you are right or wrong, but I'm not going to give answers to what could easily be homework questions from a basic Computer class.

(Question 5 I don't understand what they are looking for).

Private

1.  Sounds good.  That's usually the first place to start - ping something.  Personally, I would be asking the answer more questions regarding the system...
2.  If that was the exact question, then this is a trick question.  See http://www.easydesksoftware.com/news/news28.htm
3.  Technically I think your answer would be accurate.  Personally, I suspect they were looking for the various wifi (802.11) standards, a, b, g, n
4.  Nope.  There are multiple answers to this though.  Although there is an element of truth to your answer, it is definitely not correct.  see http://compnetworking.about.com/gi/dynamic/offsite.htm?site=http%3A%2F%2Fwww.techfest.com%2Fnetworking%2Flan%2Fethernet5.htm

Yes, I could answer the questions outright.  But if you truly want a refresher, then you shouldn't be focusing on JUST these questions, but on the topics in general.  The links I provided - if you read them, should be suitable for this purpose.

Thanks leew,
Its a junior position anywayz..and they do need a refresher.I would go thru your links and also try to get a hold on some more networking concepts.
I also remembered one more question:
1.you have a 169.x.x.x ip ..can u ping the yahoo server.
I answered no,i am closing this thread but would be obliged if you can answer this too.
Thanks for all your help.

Technically, that's not a reserved address.  As a result, it's possible.  But again, it depends.  If using Windows Automatic IP addressing, then that is the first octet used is 169 and in all likelihood, no you couldn't
