These 3 computers I selected and all of them are the best for using zebra

games.

First PC is good for PC but it doesn’t have very big graphics card and RAM.

Because nowadays most of things just need 512MB graphics card to run the

Mr: Bragg

H:Betc NationalUnit 2 BRG2.2D1suitable computer.doc 18/10/2007

pc. It has enough hard drive and processor is enough but the price are very

high.

Second PC I selected has more hard drive, RAM, and processor speed is

faster than the first PC and it’s much cheaper than the first PC. Graphics card

can support most of the things because of bigger RAM but might not work on

new coming software and games.

The Third PC I selected is the faster computer I could find and has the bigger

RAM, hard drive, and especially the graphics card is much bigger and support

every single software, game and windows. The price for this PC is very low

but the only thing it doesn’t has is the monitor which you can buy from any

computer shop in about 150 20 inches. In total the price are only £949.99 and

it nothing compares to the first computer. I believe this computer is perfect for

zebra games.

Compare Windows XP and MAC OS X system

I

n this piece of work I will compare 2 different computer systems and explain

which one is better and easy to use for the organisation and provide better

security.

The OSX windows is made by apple, It works similar to the pc’s that you can

access documents through a desktop. They also run the same programs but

their operating systems are not compatible for each other so shouldn’t try to

run them. However using Floppy disk to transfer data to pc is very difficult. If

there is fault in pc system it can easily be fixed from DOS (disk operating

system) but on apple if there is any fault you will have to call apple technician

to get the system fixed because it’s hard to fix and the commands are very

difficult to remember.

I

believe PC is better than the apple O, MAC even though apple is faster but

PC system is easily repairable and it’s hard to transfer data from apple MAC

floppy disk to pc but from PC data can easily be transfer to the apple O, MAC.

However PC and apple command are very different, apple command are hard

to remember than PC. On PC all hardware can be access from the windows

system.

and work very good in protecting from any

virus.

Full system scan:

As you can see the print screen of system

scanning. If the software finds any anti virus it

will appear in the file column.

I

nstall service pack 2:

You can see the service pack 2 is already

installed in my pc and its working perfect

against any kind of threats. If you already have

service pack2 you cant install it again on the pc

while there is the same programme working.

Clean up tool:

It is one of most useable tool to clean up your

systems file. For example, if you want to clean one

of your’s system drive than you can use this tool to

clean the drive. I am showing the print screen as a

evidence.

Drive formatting:

There are 2 ways to format your drive. One by

my computer and right click on the drive you

want to format and click on format than select

any option that looks feasible for you and than

click start.

Create folders:

If you right click on the mouse you will see the option

click on new and it will open a new small window which

will be connected to new and the first option which is

folder if you click on it, it will create a new folder for you

like this.

These are the

options you will

see when you

Copy and delete files:

If you want to delete any file from your computer all you

need to do is right click on the file and press delete and it will

delete the file from your pc. After deleting the file from

computer it goes it into recycle bin ad stays there until you

remove it from there.

Copying file is similar to the deleting. All you do is right click on the file you

want to copy and to save it you go on the folder you want to save your file in

and click paste.

Back up to CD using compression software=

To back up data using CD compression software, you need to have win ZIP

which is very famous compression software and it compress the file and make

the file size smaller than you can burn the data on the CD and have a back

up. The other way of having back up is, using external or inter hard drive

partition so you can have all the data save in these hard drive for back up.

1 day log

First days of college we were given a pc which we have to set up by

connecting all the cables and turn it on.

First of all we have to unpack all the stuff and look for the cable that we need

for turning on the pc and we didn’t have some of the cables like Power cable,

VGA (Video Graphics Array) and the mouse. When I got all the cables I

connect keyboard and mouse to the CPU and than we connect the VGA cable

from screen to CPU and than we connect the internet cable to the CPU and

turned it on and it worked perfect and also got connect to the internet.
