Basic words and meanings in the computer language

Serverman — Tue, 27 Oct 2009 18:00:28 GMT

I have decided to write a short guide on what words mean, seeing that alot of people don't know anything at all about basic computer/internet language.

This will basically be a dictionary where i explain the meaning of words.
This is not only a guide to you, but also as a test for me, so i can see how well i know this stuff (i am attending to computer and electronics class)

Binary:
First of all i want to start by writing a little bit about the basic system the computer uses.
Your computer uses a number system called the binary system.
Binary is built of 2 things, 0 or 1 (as you probably already have heard of). 0 and 1 can represent a number of things, when we talk about computers and electronics, we usually mean high or low voltage. Computers use the binary system because it is easy to make apart, just think... For a computer, what is the easiest to see the difference of?
4.12321 volt/4.12322 volt
or:
0volt/5volt
To me that is quite clear ;) Now you may be wondering how we can do anything with that? Well, you have probably heard about Byte, like for example in KB or MB (yes, there is a reason i write it with caps, i will tell you about this later). One byte is the same as eight bit. This makes for alot more usage than just having 1 or 0. For example: We can make a number as high as: 255 (not that much, but better than just 1 ;)) Now, that brings us onto how the binary number system and calculations go.
Let us start with the basics:
0110=6 how do i know this? Easy - to do it you will most likely have to start reading at the right side, the number all the way to the right has the value of 1, so if the first one is 1 we take 1 into our equation, relax, i know that was explained in a stupid way >.< Lets take the second number too. That has the value of 2 (it is the last value multiplied by 2), so if that is 1 we take 2 into our equation. Then what is the next number? Think about it before reading on ;) Try to solve this one yourself...

The next number represents the value of 4 (2 multiplied by 2), so if that is 1 we add 4.
Next number after that is 8 (4 multiplied by 2), so if that is 1 we add 8. and so on...
The number 0110 would give us the equation in decimal: 4+2=6.
Now that is a really tough way to do it, and i know there is easier methods, but i won't explain that any further.

I think that is enough about the binary system.

Bits and bytes, the difference between b and B

Ok, i see alot of people writing things like omg! teh file iz 800mb! :O
What most of them mean is that the file is 800MB that is two entirely different numbers.
first of all, lets look at the first number; 800mb now i shall tell you what this actually sais: 800millibit that is actually 0,1MB (correct me if i am wrong, but i believe milli= 10^-3, wich should give us this number..) Why is it 0,1 and not 0,8? Because 1 byte=8bit. I probably messed alot around in your head right there, didnt i?
The point here is that while you may have thought that it dosen't really matter, it actually does... In this case, it is a 799,9MB difference ;)
Sorry Stroh :facepalm:

Now lets talk about what has to do with networks.
LAN:
LAN stands for Local Area Network, and it is exactly what you would think it is. It is a local network, as simple as that. I will mess with your head later in the guide ;)
WAN:
WAN stands for Wide Area Network, and it is where you connect the plug that goes out to your ISP( Internet Service Provider)

Now for the messing with your head:
Lets make a scenario:
you set up a LAN at your home, as you already have, since you are seeing this. Then you have your plug to your ISP on the WAN port on your combined router/switch/access point (if you are using wireless). But if you set up another LAN under your LAN again. Will your first LAN then be a WAN for the second router?
Hang on and i'll quickly draw something for you ;)
Here:

Ok, the WAN for Router 1 will be the ISP's network
The WAN for Router 2 will be Router1's network. Your ISP does not even know you have set up two routers.
So to sum up: WAN will always be one step closer to you ISP.

Now i want to ask you all some questions that i want answered:
Does anything get stored on the Internet?
What is it that the Internet consists of? (physically)

And that is it =) I may add more when i see the confusion about a certain topic arise ;)
Also, i want answers to those questions :) (By the way, i know the answers i just want to raise some awareness of what the Internet actually is)
Oh, and: Sorry for the giant pic >.<

How to use Command Prompt at school

snocher — Tue, 27 Oct 2009 16:15:38 GMT

first off if you dont know what Command Prompt is: contiue reading
if you aready do skip down to RED title
[copied from What is a command prompt? - Knowledge Base]

Quote:

What is a command prompt?

A command prompt is a non-graphical interface that allows you to interact with your operating system. At the command prompt, you enter commands by typing their names followed by options and arguments. Most modern computers use a graphical user interface (GUI), which allows users to more intuitively access programs and documents. However, some programs and commands are still only available only through a command prompt. To access the command prompt, follow the instructions appropriate to your operating system.
Windows

To access the command prompt in Windows, from the Start menu, select Run... . In the "Open:" field, enter cmd (Windows NT, 2000, XP, and Vista) or command (Windows 95, 98, and Me).
For information about commands you can use in the Windows command prompt, see What are some examples of common DOS commands?
Mac OS X

Mac OS X is built on a version of Unix called Darwin. To access the Unix command prompt in Mac OS X, open the Terminal application. It is located by default inside the Utilities folder, which in turn is inside the Applications folder.
For information about Unix commands, see Introduction to Unix commands.
Unix

When you log into a Unix computer, your shell begins to run and provides you with a command prompt. The command prompt's appearance varies depending on the shell you're using. For information to help you select a shell, see In Unix, where can I get information on differences between the various shells?
For information about Unix commands, see Introduction to Unix commands.

Okey, now that we know what Command Prompt/Cmd is we can continue.

most schools ban/block cmd but as long as you have notepad you can always create a batch file. but if your like me and you like to have command prompt open and there for you. There is a simple script that will allow this to happen.

Copy and paste this into notepad

Code:

 

run.com

command.com

save it as Whatever.bat click on it and there you go command prompt open and in your control. there are meny things you can do in command prompt and there are plenty of people with tuts on that so i wont get into that those details.

if you wish to know more about Command prompt pm me and i will try to be as helpful as i can.
