RESPECT FOR WOMEN IS PARAMOUNTNetworking
Computers, like any other piece of electronic equipment, need special care and attention in order to perform properly and safely.
There are many tasks that should be done, and caution that should be taken to ensure proper working, and safety of all components of the computer system.
In this unit, we shall concentrate on some daily do’s and don’ts and precautions that any one in a computing environment should know.
The computer laboratory Rules and Regulations
1. Computer components should be kept
dust-free. Avoid smoking and exposing computers to dust.
2. Never try to remove the cover on your computer or touch inside the system unit. There are many sensitive components. Instead, take it to a qualified technician.
3. Keep all liquids and food items away from your computer.
4. Never use your computer during a storm. The computer is connected to electricity and that means that lightning could be conducted on the computer.
5. Physically, be careful, avoid knocking and dropping any hardware to the ground as this could cause any of the delicate components to break or be damaged and stop working.
6. Proper shut down of computers should be followed to avoid disk and system failure (avoid abrupt switching off)
7. Be careful when using the internet. Do not accept downloads from Internet sites that you don’t know and trust.
8. Avoid making hardware connections to the motherboard when the computer is on. Eg keyboard, monitor and mouse connections.
9. Don’t bring magnetic devices to the lab. The computer has magnetic disks which can be spoilt if they come near other magnetic fields.
10. Handle delicate storage devices with care. Don’t touch the inner surface of Compact disks and Floppy disks. Safely remove Flash disks from the system.
11. Avoid excessively bright and flickering computer monitors. The brightness of the computer monitors should be adjusted to avoid eye strain.
12. Always Sit upright to avoid muscle pains and backaches caused by poor sitting posture.
Management Of Computers And Their Environments
After the establishment of the computer laboratory, a number of precautions should be observed to provide a safe conducive environment for teaching and learning as seen below:
1. Avoid direct sunlight and high Temperatures that may damage hardware components.
2. Always use surge protectors, Uninterruptible Power supply (UPS) or voltage stabilizers to ensure steady power supply to safeguard their system.
3.Protection against fires. A computer room should have fire extinguishers of carbon dioxide but not water or powder.
4.Proper cable installation and placement. Cables should be preferably along walls, avoiding the danger of exposing the user to electric shock
5. Burglar proofing avoid unauthorized access to the computer room.
Fit strong locks, doors, windows and roofing. Security should be
good around the computer room to avoid thefts.
6. Overcrowding of either machines or people should be avoided.
7. Always install lightening conductors to the computer laboratory to protect the machines and the users of the computers.
8. Ventilation should be good. Good aeration enables the computer to cool and hence avoids overheating
9. Minimize Electrical noise/interferences in the computer environment.
Definition:
10. Dust control. When setting up the computer laboratory, consider a location away from excessive dust.
11. Dump Control: Humidity must be regulated in the computer laboratory to remain at an optimum 50%.
12. A computer room should have enough light to avoid eyestrain and headaches.
13. Radiation filter screens should be fitted to reduce the light that reaches the eye.
14.Standard furniture: The table on which a computer is placed must be strong and wide enough to bear the weight and accommodate all the peripheral devices
Maintenance of Computers In Good Working Conditions
The following measures should always be carried out to keep computers in good working conditions:
1. Regular servicing should be done for hardware and software updates to ensure proper working conditions of the computers
2. Computers require special cleaning even on the outside including hardware parts such as the mouse and keyboard to perform correctly
3. Always use optimizer utilities
that modify programs to make computers to improve performance and make them to run more quickly.
4. Always use and regularly updated antivirus software. Viruses and worms are horrible computer-unfriendly programs that can crash your system and cause damage.
5. Avoid Installation Marathons
7. Carry out Disk Defragmentation when necessary.
The Ethics And Integrity In Computer Use
Definitions:
Computer Ethics refers to the right or wrong behaviour exercised when using computers.
“In Pursuit of a ‘Ten Commandments’ for Computer Ethics.”
The Computer Ethics Institute published them as follows in 1992:
