Computers and other accessories have been installed in the computer laboratory. Printers" scanners" multi-media projectors are some of them. 

Computers and other accessories in a lab are expensive and valuable. A large amount of money have to be spent to repair a device, if it is damaged or to replace a new one. Therefore, it is your responsibility to use them properly and keep them safe. 

We must practise to operate the computer correctly from our childhood. For that follow the guidelines given below. 

Anyhow, the above steps may differ in modern computers (like laptop computers) which come with a single power button. 

The functioning computers should be shut down in a proper way. Otherwise, the life span of the computer may be shortened.

Dear children, you always get advices to be a good child at home and at school. These advices are called ethics, values, or good customs. 

Good practices help to lead a good life. Similarly, there is a set of ethics that should be followed to use the computer properly. 

They are identified as 'Computer ethics'.

This code of ethics can be considered as a set of guidelines that help you to use the computer properly. 

In additon, there can be some other rules and regulations related to your laboratory.

It is common for various health problems to occur when using computers constantly. Most of the illnesses occur due to the lack of maintaining a correct posture. So we need to practise maintaining a correct posture from our childhood. 

In addition, adjust the brightness and the contrast of the computer screen to suit your eye. Often give a rest to your eye if you are working on your computer for a long period of time. 

Although an incorrect posture can cause health issues, the computer is not a device that can be discarded. Therefore, we must use the computer properly to avoid such problems. 

Since, these hazards can cause damages for generations, they must be disposed properly. For that, the 3R system can be used. 

It is not necessary to upgrade to new equipment periodically if we maintain existing equipment properly as to use them for a long time. 

This reduces the amount of waste that is released to the environment. 

2. Reuse 

When purchasing new equipment, consider donating or selling the old equipment if they are in working condition, without discarding them. 

If it is not in working condition, then it can be utilized for other purposes. 

For instance, as shown in the picture, an empty monitor can be used as a flower pot and a casing of the system unit can be used as a garbage bin. 

The amount of waste that is released to the environment is therefore minimal. 

3. Recycle 

Equipment which are not repairable or reusable, should be recycled without discarding them. It should be handed over to a electronic waste recycling company. 

To protect the information stored in the computer from outsiders, a secret word can be set in the computer. That is known as a password.

👉The password must be a collection of letters (A-Z), numbers (0 - 9), and symbols (@, #, $). It should have a minimum of 8 characters including at least one of the above types. 

👉The password must not include some simple information like your name, birthday, etc. which can be easily guessed. 

👉You can give a password hint. In case you forget the password, you can give a word or a statement as a hint that will help you to recall it again. 

👉By giving an e-mail address, the password can be restored.
