POSSIBLE PRECAUTIONARY MEASURES1. BURGLAR PROOFING
Physical access to the computer room should be restricted to ensure that only authorized persons get access to the computers.
To prevent unauthorized access to the computer room, the following controls should be implemented:
2. VENTILATION.
Both computers and human beings emit heat energy into the environment. Therefore, the computer room must have good circulation of air to avoid overheating and suffocation.
Proper ventilation enables the computers to cool, and therefore, avoids damaging the electronic parts. The following facilities can ensure proper ventilation in a room:
3. DUST CONTROL
The service should include; blowing dust from the System unit, cleaning the floppy drives, cleaning the Keyboard, cleaning the Monitor externally, and also cleaning all peripheral devices such as Printers and Mouse. 4. DUMP CONTROL.
Humidity in the computer laboratory must be regulated to remain at an optimum 50%. If the humidity is low, it allows static electricity to build up and causes damage to sensitive electronic components. Similarly, high humidity of over 70% causes rusting of the metallic parts of the computer system.
5. HANDLING OF MATERIALS & EQUIPMENT.
Computer devices must be handled with a lot of care as they are extremely fragile and can easily get damaged. Dropping or bumping can cause permanent damage on the device, e.g., to transport the System unit always handle it on its frame.

Input of data is a main function because all other functions depend on the incoming data for processing and output.  Functions of a Computer 2. processingProcessing and storage are sometimes broken down as separate basic functions of a computer. However, looking at this critical idea keenly, we notice that processing and storage are sometimes inseparable this is because processing devices rely heavily on storage devices vis a vis. Processing is an act where a computer converts raw meaningless piece of information called data into a more meaningful piece of information. This is normally done with a closer help of primary storage devices such as the RAM, and special types of memories such as the registers, buffers and cache memory. Processing is a main function of a computer because of the conversion, manipulation of numeric data and logical decisions. 3. OutputThis is an act for a computer to display the result of a processing activity. This can be done using output devices such as the monitor, printer, plotter, speakers etc.
The functions of a computer system cannot be complete without the output, simply because it gives a feedback of the result for the computer user to digest, change, amend, store or print. 18/4/2019 A spreadsheet has the following entries.
