B) Install and configure a DVD rewrite drive supplied.
Step 1)
Before you start: Ground yourself. Lightly touch your PC's metal chassis to discharge any current from your body. Then unplug the power cable slowly.
Turn off the computer and open the case. Locate an available PCI slot for the MPEG-to decoder card (if your kit includes one). If you're installing a SCSI drive and you don't yet have a SCSI controller in the system, you'll need a second slot for the SCSI card.
PCI : Stands for Peripheral Component Interconnect, a local bus standard developed
by Intel Corporation.
MPEG : Moving Picture Experts Group develops standards for digital video and
audio compression.
SCSIS : Stands for small Computer System Interface, an interface that serves as an
expansion bus that can be used to connect hard disk drives, tape drives, and
other hardware components.
To install any hardware the computer or the Base Unit has to be unplug the
power and the cable, for example the picture showing below.
Step 3)
Locate an available 5.25-inch drive bay that opens into the front of the case, and Remove the bay cover if necessary.
Step 4)
Configure the jumpers on your DVD drive. For an IDE drive, set the jumpers for either master, slave, or sole drive, depending on what else is on the channel. For a SCSI drive, set the jumpers to the correct ID or termination setting
Step 5)
Secure the drive and make sure is properly adjusted.
Step 6)
Attach the cables. Connect the DVD drive to the IDE or SCSI bus and to the power supply. Also connect the DVD drive to your sound card - or connect the decoder card (if included) to the DVD drive and sound card. (If you already have a CD-ROM drive, you can use a micro stereo patch cord to connect the external headphone jack on the DVD drive to your sound card's line-in jack).

The range of utility software
C) As additional information, you will describe the range of utility software currently available. You will include this in tabular form on your blog, containing utility type and detailed descriptions of the use and purpose of the utility.
Utility Sofware
Description
Purpose
Firewalls
Is a software program and is a system designed to prevent unauthorized access to or from a private network. The reason to update your PC every day or week is because the new viruses out there developed every day or every five minutes around the world so in order to detect the latest malicious programs for example worms or viruses
The effect of a Anti-virus is to detect and respond to malicious software such as worms or viruses some time the anti-virus software does not recognize the latest virus program. So to secure the computer anti-virus you must needs to update you PC every day or ones a week.
Disk defragmenters
Disk defragmenters it can detect computer files whose contents are stored on the hard disk in disjointed fragments, and move the fragments together to increase efficiency.
The purpose of the disk defragmenters is to detect computer files and to move then fragment files.
Backup
It can transfer data from one computer to another from the web server. It can transfer anything for example text, images, music video, file.
