Lab46 Wiki

This is one single file that is a complete representation of a single storage device. A storage device could be a cd, dvd, harddrive, floppy disk or anything else.

I'm going to reformat my computer and my external hdd but I don't want to lose all the information on my external hdd. Now I use some software to create a disk image of every file on the hdd while I reformat everything.

Note: Aptituse itself is a high level-interface designed for the package manager.

This is a useful command in order to see what packages are installed on a system. After 'aptitude search' insert the name of a package you are looking for and it will display a list of every package available with that name. It also lists if they are currently installed or not which is marked by an 'i' next to the packages name.

This is a tool that allows you to install available packages.

So you're doing a NM install with xen and you need a few xen packages. After seaching with aptitude you decide you need to install xen-tools. You input “aptitude install xen-tools” and there ya go, the screen spits out

vmserver01:~# aptitude install xen-tools

*NOTE: In this case it says 0 files altered or installed because Ialready have this package installed.*

There are many forms but in general it is a resource that is used by clients. It is a piece of hardware with software on it that allows clients to use it for their benefit.

Few examples.

A printer server would allow clients to access the printer through a network and print from this server.

A storage server would allow clients to access a storage device through a network and save their data.

Awesomeness. It is the interaction between the user of the computer and the computer itself that is not GUI. It is just a keyboard and text environment versus a visual point a click interface. You type out and tell the computer what to do instead of poking it with your mouse.

lab46:~$ cd stuff
lab46:~/stuff$ ls
0x8  0x9  0xa
lab46:~/stuff$

Simply put this is the much gooder version of vi. It is a package that installs the goodness that comes with vi. As regular vi is very very hurtful to the brain wrinkles and make baby jesus cry.

I.E. vim allows you to search through a text file with simplicity. It allows you to cut and paste with a few commands. It allows you to 'jump' around the file with ease. This is all compared to my short experience with regular vi where I could not even understand how to insert text where I wanted it. (or maybe it was all the lead paint chips I ate as a child, who knows)

In computery terms this is a digital space of memory where a large amount of like data is stored. It aims to organize large amounts of data. keyword organize.

I.E. At a bank there are (assuming) thousands of accounts that people have stored there. Let's say these accounts keep all the standard information of name, address, phone number and savings account. A database would store of of this information in files. The files would most likely be saved by the name of the individual of who the account belongs too. So instead of having all of this information strewn all over it's all neat and tidy tucked away in this database.

Identification of chosen keyword (unless you update the section heading above).

Definition (in your own words) of the chosen keyword.

Demonstration of the chosen keyword.

If you wish to aid your definition with a code sample, you can do so by using a wiki code block, an example follows:

/*
 * Sample code block
 */
#include <stdio.h>
 
int main()
{
    return(0);
}

Alternatively (or additionally), if you want to demonstrate something on the command-line, you can do so as follows:

lab46:~$ cd src
lab46:~/src$ gcc -o hello hello.c
lab46:~/src$ ./hello
Hello, World!
lab46:~/src$ 

State the course objective

In your own words, define what that objective entails.

State the method you will use for measuring successful academic/intellectual achievement of this objective.

Follow your method and obtain a measurement. Document the results here.

Reflect upon your results of the measurement to ascertain your achievement of the particular course objective.

• How did you do?
• Is there room for improvement?
• Could the measurement process be enhanced to be more effective?
• Do you think this enhancement would be efficient to employ?
• Could the course objective be altered to be more applicable? How would you alter it?
