Part 1

These are devices that use electronic processing that at that given time is the fastest processing available. High performance computing utilizes these machines as their main tool for calculations.

In modern times they are used for calculations that involve very extensive computing. IE: Quantum physics, molecular modeling, gas exploration

Simply put this is a person that is in charge of a computer or a network of computers. Their duties range in software and in hardware. If a server or computer needs the software updated they are in charge of doing it. Also if there are service outages they are on top of repairing these services.

The software on a server is out of date, the system admin comes and updates the software to the server.

A network of computing devices designed to act as one single unit.

A very good use of this is linking several 'slower' machines together to work together in order to compute your desired software. This is much more efficient than going out and buying a new system or upgrading your system every time you need more processing power or speed for your calculations.

This is a tool used to calculate how many operations the processor is calculating per second. It's a very useful tool in HPC if you need a calculations per second and are unsure of the machines or clusters speed.

It can be primarly used to calculate the processing speed of a super computer.

This let's on operating system emulate several other operating systems while making the best use of the systems resources and hardware. The entire system is not emulated. This is not always the best solution as it may be more lenient on resources, the operating system must be worked on in order to let it work with this.

I.E. I am going to run a virtual machine on a desktop with very low resources available (very outdated computer.) So in this situation I decide to run a para-virtualization setup as it is more resource friendly even though it requires a little more work and has a few more restrictions on it compared to full virtualization.

A Unix account that has privelages to edit, save or open any files in the filesystem. It is used for system administration.

Someone is trying to do a VM install but they cannot download and install packages as they are not a root user. They then log in as root and they are now allowed to download and install the packages.

Completely erasing a memory allocation to ground zero and then beginning it a new with a new file system (usually the same as before).

At the beginning of a VM install you would usually reformat the drive and do a frech install of the OS. There isn't anything on the drive that is of any real use, so you have no use in keeping anything on the drive intact. Therefore, erase it and start fresh.

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?

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.

vmserver01: aptitude search xen
p   linux-headers-2.6.26-2-common-xen                       - Common header files for Linux 2.6.26-2-xen

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$
