A school decides to harmonize the operation of its two campuses using a distributed database system as well as install air conditioners  and uninterrupted power supply in the computer laboratory.

(a) State three (i) Importance of using distributed database (ii) disadvantages of using computer processing information in the school

(b) Give two reasons for installing the; (i) air conditioners (ii) uninterrupted power supply devices

Answer Details

(a)

(i) Importance of using distributed database:

1. Data sharing: A distributed database allows multiple users to access and share data from different locations. This ensures that all users have access to the same updated information, which increases efficiency and reduces errors.
2. High availability: With a distributed database, the data is stored across multiple locations. This ensures that if one node fails, the data can still be accessed from another node, increasing the availability of the system.
3. Scalability: Distributed databases can be easily scaled up by adding more nodes to the system, allowing for increased storage and processing capacity.

(ii) Disadvantages of using computer processing information in the school:

1. Security risks: Computer systems are susceptible to cyber-attacks and viruses, which can compromise sensitive information such as student records and financial data.
2. Maintenance costs: Maintaining computer systems can be expensive, as hardware and software require regular updates and repairs.
3. Technical knowledge: Operating and maintaining computer systems requires technical expertise, which may not be readily available to all staff and students.

(b)

(i) Reasons for installing air conditioners:

1. Comfort: Air conditioners provide a comfortable and cool environment, which is important for students and staff to concentrate and perform well.
2. Health: Air conditioners help to filter out pollutants and allergens from the air, improving indoor air quality and reducing the risk of respiratory illnesses.

(ii) Reasons for installing uninterrupted power supply devices:

1. Protection of data: Power outages can result in data loss or corruption, which can be detrimental to the school's operations. Uninterrupted power supply devices ensure that critical systems remain online during power outages, protecting the school's data.
2. Business continuity: Power outages can disrupt the school's operations, causing delays and financial losses. Uninterrupted power supply devices help to ensure that critical systems remain operational during power outages, minimizing disruption and maintaining business continuity.
