Determine Server Memory

I'm suprised you didn't do a "man free" on this.

Its very obvious why the numbers are a little different.

 

If you did a free -b you would get yet another number.. It is time to refresh your binary math knowledge.. remember that a k is 1024 bytes, and a meg is 1024 k's, so if you divide your k number by 1024 you will get your m number.. amazing, huh?

 

Sarcasm? hmm,, maybe I did rib you a bit but I also gave you the information you asked for. Whenever you are new at anything you can expect a little kidding, and I do think that what I provided was with good intent and with constructive content. If your skin is that thin perhaps you might want to consider working where you don't have to interact with people.

Your attitude and comebacks will make it less likely that your peers are going to support you in the future. That is a shame, because peer exchange and tribal knowledge are very important in this industry.

Every one of us has gone through the newbie stage and enjoyed the good natured banter that comes along with advice from those more experienced than ourselves.

I stand by my original statement and reiterate my good advice to a newcomer that one cannot overstate the importance of understanding binary number math. You need to be able to add, subtract multiply and divide in binary, octal and hex if you want to be proficient in this industry. Everything is based on binary. Octal and hex and BCD are representations of binary to be more human readable. Understanding Boolean algebra and register shifting goes a long ways toward explaining subnetting theory.

Take as a minor example the fact that an IP address is in reality a single binary number. An IP address is not four decimal numbers each with a 255 limit. It is only represented as four decimal coded octets to make it easier for people to remember. Until you grasp how a binary IP address is manipulated by a binary subnet mask you will never fully understand routing and you will be at a disadvantage in any networking industry. Computers and routers may interpret decimal but they work in binary.

192.168.0.1 = 11000000.10101000.00000000.00000001 = 11000000101010000000000000000001 = 0xC0A80001 = C0.A8.00.01 = 3232235521

This is offered as constructive advice, but I suspect you will interpret it as a demeaning statement.
