This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

In this assignment I will be writing about undertaking routine maintenance such as Software maintenance and hardware maintenance. Within software maintenance I will talk about: upgrading software to a new version, path installations like fixing bug or software and scheduling of maintenance tasks such as daily backs etc. Also within the hardware maintenance I will write about: cleaning products things like keyboards, routine installations of printer or such, the basic health and safety, Regulatory requirements, file management where creating folders and back up producers.

Scheduling of maintenance tasks:

Daily- Backups- Back up should be made incase of computer failure or sudden breakdown. Backups generally means when the computer files and work are copied to another location such as CD incase of deleted work or corrupted files. Backups should be done daily as its a common thing to happen where important work can be lost or delete which can be done for random purposes and in case it does backups can help users get the important files found again.

Weekly-. Check antivirus- antivirus should be check weekly so the computer can be scan and cleaned from the computer keeping it safe and leave it undone for too long can cause virus to enter and then best it can be done it by completing weekly virus checks for any new treats and that if any viruses are done they can be removed quickly and check all the things are protected and turned on providing best security.

Monthly- clean inside of case, clean mouse - cleaning parts of the component is key as dirt or dust can build cause things to come in the way such as dust in the computer fan and best way it can be done is by using compressed air, also cleaning a mouse is important as it could interfere with the mouse movements and if you have a mouse with a ball dirt can get stuck onto the ball. And other things to keep are like keyboards as mess can get between gaps causing buttons to stick or jam.

Sixth monthly e.g. scan disk/ defragmentation - This can be done less often simply because it's rather time consuming but completing the task help the computer run properly. The scan disk scans the computer drive to check that there are no problem and running correctly .Defrag organise the file system to help the windows read files better.

Annual checks-check warranties- checking warranties in important for the Pc as all computer or most computer components have warranties on them which are handy for any replacement or repairs incase of any breakdowns and warranties allows you to get it fixed or new one.

Dust Inside the Case

Health and Safety

Lighting- Lighting can used problems to the eyes and cause blurred or double vision and headaches with frequent changes in glasses, this lighting can be used by strong brightness or contrast on the computer monitor screen, or other sources like strong light from windows or lights which would reflect off the screen into the eyes. There are many ways to avoid problems from lighting such as setting the contrast to a suitable level to suit you, make sure that the computer screen is not directly facing windows where sun can reflect it and not sitting to close to the screen.

Temperature:- Computer users have to have the right temperature room, where its not to hot or cold and also have to make sure that your computer is put in the correct place for example a laptop should be put on a flat surface and not on legs as the heat of the battery can cause burns on legs.

Chairs - have a suitable chair when using a computer is key as it prevents any back or point problems which can be caused by poor back support. The best way to avoid this is to have a good chair with has back support which can be adjusted to suit you and ones which come up to its original position. Should have adjust or some sort of arm rest and chairs where height can be adjusted and normally with a Four leg base.

Regulatory requirements

1.regualtion 1 defines a operate for a self- employed and they have to have the following criteria: have no discretion on a computer, use a computer for up to more then one hour and have high attention and concentration levels

2..Second regulation sets out tasks for risk assessment where people access the risk, draw upon extra information and draw valid and reliable conclusion and finally recognise their own limitations and call on extra expertise

3. third regulation has been set up to set standards for equipment such as suitable lighting with no glares or reflection, comfortable temperature and humidatiy, software which as suitable for the tasks, chairs with adjustable height and etc.

4. Regulation 4 requires employers to plan breaks or changes of activity into the work routine. These breaks can be taken either at the keyboard but normally advised to take a different activity and break times should preferably 5- 10 mins at keyboard

5. Regulation 5 gives users a right to free eye and eyesight tests upon starting computer work and at regular intervals, the employers have the option to advise the user to a optician as they would need testing after all staring at computer.

6. Regulations 6 obliges the employers to be provided with education and training in the health and safety aspects of computer work such as health effects of a computer, good posture and keyboard technique, the characteristics of software and work breaks etc.

Health and safety act

Repetitive Strain Injury - RSI - can be caused by a mixture of quick keyboard movements by the arm in a static position over a very long time. There are several factors which can lead to RSI such as inadequate breaks, an excessive work load, and working in a awaked position. To prevent these symptoms make sure you watch how you work (posture), take regular breaks and take you time when you work.

File management

The main purpose of creating folders is to stay organised and help you find work easily as work can be dragged within the folder and you can also be sub folders inside so its even organised for example I could have a folder called "school work" within that folders I can have other folders made with different subject.

The way to create is to click File and go to New and click on Folder or you can also do it by left clicking and finding it the same way

Once clicked a icon of a folder would appear called New Folder.

To name the folder that has been created to what you want it to, left click on the folder and you should see Rename and will able you to rename to what is appropriate.

Back up procedures

There are three main types of back

A differential backup is a backup of every file on a file system which has changed since the last full backup.

The alternatives to a differential backup are incremental backup and full backup.

A differential backup is not as fast as an incremental backup, but it is faster than a full backup. A differential backup requires more storage space than an incremental backup, but less than a full backup

An incremental backup is a backup of every file on a file system which has changed since the last backup

An incremental backup is the fastest backup and requires the least storage space on the backup media. However, incremental backups also require the longest time

An incremental backup is the fastest backup and requires the least storage space on the backup media. However, incremental backups also require the longest time

A full backup takes longer to accomplish and requires the most storage space on the backup media, but it also provides the quickest restore times.

A full backup should be performed weekly or monthly on production systems
