Computer Byte and strong passwords

Q:
What do all those error codes (like 404) mean?
A:
It happens to all of us. We're surfing along, and up comes an error.
What do all those error codes mean?
Here's a quick rundown of the most common:
 
400 - Bad Request - You probably typed in a URL wrong,
the server has no clue what you're looking for,
or you aren't allowed to have access.
Usually, it's a matter of the URL being typing in wrong.
Maybe you mixed upper and lowercase letters or something.
 
401- Unauthorized Request - you tried to get to something
on the web server you're not allowed to play with.
In other words, you ain't on the party list.
 
403 - Forbidden - You can't access the page.
You may not have access (it may require a password),
or it may be blocked from your domain.
 
404- Not Found - The page you were trying to look at was not
found on the server.
This is probably the most common error you'll come across.
What has probably happened is that the web page
you were going to has been removed or re-named.
 
500 - Internal error - Usually caused by a CGI error.
You fill out a form, but the script used to process it is not working properly.
 
503 - Service Unavailable - The server may be overloaded,
down, or have other similar problems. Try later.

OK, This next concerns all of us
 
Computers 101
Q:
How can I ensure that I have the strongest password possible to secure my computer from any intruders?
A:Given enough time and using the correct tools,
a hacker can break into a computer and access the files.
One reason hackers are able to break into computer systems
so easily is because the user did not create a strong enough password.
 
Many computer users create passwords after their family pets,
favorite objects and familiar words.
 
This is an extremely bad idea.
 
For starters, don’t choose a password that is in the dictionary.
It takes password cracking software about 10 seconds
to crack a word that is in the dictionary.
 
The password cracking software uses a dictionary file
 which contains every word in the dictionary.
The software takes the words and sends them at the object
it is trying to crack. This dictionary file is usually easy to update,
since a site on Google provides hundreds of results.
 
For more effective passwords, try taking two or three words,
 slicing them at random points and them crunching them together.
For example, I could use house and railroad.
My outcome might result as “houroad,” which is not in the dictionary.

However the above is not always the best way to go when choosing password.
Eventually, it will be cracked, probably within nine days or so.
If you are locking important information, this is not good enough.
 
The best password that a user can create is by mixing
upper and lower case letters with numbers.
 
 An example of this would be “5xBM34z.”
 
This password would probably take around 238 years or so to crack.
(I don’t know a single hacker who would want to wait that long).
These types of passwords are hard to memorize, but are the hardest to crack.
 
 
The length of the password is a major factor as well.
The longer the password, the longer it takes to crack.
 
To make the most complex password, a user can also add
symbols to their password.
Again, the greater the complexity of the password,
the greater the time it takes to break it.
