Don't worry you'll soon catch up

Seriously go onto google an dgoogle what we are talking about and start looking at it and seeing if its something that you'd be interested in. Its the only way you're going to find out if what you want to do is actually what you want to do ( if that makes sense )

Will do. At the moment I am learning binary mathematics and I want to cry. It's so damn boring. Also doing sone SQL refresher course as well. Once I'm done with that I will refresh my memory of RAID configs. So much to learn!

I'm rubbish at binary maths - it's the one bit of the CCNA that gave me real trouble - but I can do subnet calculations in my head without worrying about binary. It's a doddle, you just need to remember multiples of two.

It's bleedin wonderful for things like collapsing multiple domain controllers onto the same tin though.

Sorry I don't understand the use of the words DB and Microsoft in the same paragraph

Binary maths. Not really done any of that since I worked on vax systems and used integer flags and had to logically or bits to the flag etc. whoops still do in c network programming


The only thing you ever need binary for these days is to and a subnet mask to an ip address to return the logical network address.

Oh, you're one of those, are you?

Bless.

Yeah I can work out the subnets in the noggin, you kind of have to in my current job as no-one technical seems to understand what a /30 is!

What a qualified Oracle DBA?. Was. I just use databases these days. currently running XE on my laptop for development. 10g on my webserver at home. And about 200 instances from 8i to 11g at work

as in 30 bits to the subnet or 11111111.11111111. 11111111.11111100.
expressed as 255.255.255.252. which means the last 2 bits are for, device addresses, 2 bits with give you 4 addresses, but you need 1 for the network, one for the broadcast address leaving 2 addresses for devices. Ideal for point to point links.

A /30
Subnetmask: 255.255.255.252 (11111111.11111111.11111111.111111 00)
Wildcard (revsese mask): 0.0.0.3 (00000000.00000000.00000000.000000 11)

You done too much cisco
