Distance learning/Bootcamp sham

[gurner]

A friend of mine recently got him self caught hook line and sinker by a sales(thing) and was roped into paying over 3 Grand for one of these distance learning shams

3+ grand to end up knowing nothing actually that useful, and panicking and doing a runner when a Network goes down the pan before his very eyes.

the company I work for primarily deals with Databases and is considered one of the best, i have no qualifications and got in on merit and sheer personality (when an interviewer asks you to throughly explain Subnetting and the OSI model, and your explanation brings a smile on their faces you know you have the job!!)

I come across Paper Qualified MCSEs all the time, I waste so much time explaining to them aspects of their job they should know, it now a running joke in the office.

I think the distance learning companies (Computeach take note) are nothing but the Arfer Dalys of the IT world

Couldn't explain subnetting and the flaming OSI model to me could you? -----------------------------------------------------

All - Application - FTP, SMTP, e.t.c
People - Presentation - ASCII, e.tc.
Seem - Session - Est. Maintain or break a session
To - Transport - connection type TCP/IP UDP IPX/SPX
Need - Network - lots of things!!
Data - Data Link - LLC MAC CSMA/CD/CA
Processing - Physical - Cards and Cables!

Subnetting is just a little bit too much to go in here, needless to say its function is to provide a greater variety of IP addresses.

Before understanding subnetting, brush up a bit on your binary. Then its childs play.

128 - 10000000
64 - 01000000
32 - 00100000
16 - 00010000
8 - 00001000
4 - 00000100
2 - 00000010
1 - 00000001

is the best way i think of demontrating binary

IP - 193.10.30.2
binary eqivalent -
11000001.00001010.00011110.00000010

Once you've got all of the binary licked, subnetting becomes a way of looking at the ip address is binary, choosing a point at which to the left is the network ID (and everyone has to have the same) and to the right is the client ID (everyone is different).

To work out how many clients you get per network, add up the number of binary digits in the client section and do 2 to the power of that number and deduct 2 (cos all 0's in the client ID means "network" and all 1's means broadcast).

has a lot of discussion on this topic I believe.

Blimey, I'd better get reading my Networking Technologies book. I'm doing the NetWare CNE track and this is my only cause for concern. -----------------------------------------------------
