The computer laboratory Definition: A computer laboratory is a special room that has been specially prepared to facilitate installation of a computer and to provide a safe conducive environment for teaching and learning of computer studies. The following factors are considered in setting of this room: I. Security of the computer programs and others resources II. Reliability of power III. The number of computers to be installed and available floor space. IV. The max no of users that the lab can accommodate.
Safety precaution and practices in the computer lab A number of practices and precautions are to be observed in order to avoid accidents or even damage of computer component inside the lab. They include: 1. Measures that protect the computers 2. Measures that protect the user 1. Measures that protect the computers The following must be followed around the computer lab i. Avoid smoking or exposing computers to dust. The two contain small abrasive particles that can damage computer components and cause wear out. ii. Avoid carrying food and beverages to the computers room. Liquid spills may cause rusting. iii. Avoid unnecessary movements in the lab.
iv.Follow the right procedures for starting the computer and shutting down the computer to avoid loss of data and damage of computer components. v. Do not open up the metallic covers of computers or peripherals devices a particularly when the power is on.
2. Protection against fire Fire extinguishers should be available in the lab and especially those with carbon dioxide. Water should always be avoided because it causes damage to the computer components. 2. Cables insulation All power cables must be properly insulated and laid away from pathways in the rooms. Lay them preferably along the walls in trunks.
Stable power supply Computers are delicate devices that requires stable source of power. Power from mains supply is not always stable and may sometimes experience power surges or under voltage. To protect the computer from such special devices called uninterruptible power supply (UPS) are connected between the computer and the mains.
The UPS perform two functions: i. It regulates the power of unstable source of power. ii. It temporarily provides power when there is a power failure. iii. Note: Devices that generally provide an alternative power are called power backups.
