Better Design Furniture has imported three refurbished medium sized electricity generators. The manager, Sam, was advised that the maximum running time for each generator is eight (8) hours. This is ideal for the company because the plant has to run for a complete twenty four hour period. With three generators running for eight hours each, this equates to twenty four (24) hours. Sam is now in dire need of a circuit that will start-up and shutdown each generator at different eight hour intervals.
According to Sam, the generators should work as follows: • Generator A 12:00 AM - 8:00 AM
• Generator B 8:00 AM - 4:00 PM • Generator C 4:00 PM - 12:00 AM
Sam has recruited your group as interns with the responsibility of designing the system that will execute the above functions. In designing the system, the group should ensure that generators are not allowed to run simultaneously, as this will result in serious damages to Sam’s equipment. In addition, there should be a disable switch which disables the power coming from the generators and enables the use of the Jamaica Public Service’s electric to power the equipment. This is necessary for the technicians to service the generators.

the overriding principle in distributed database design is that data should be stored at one central site. True or False?
The statement that the overriding principle in distributed database design is that data should be stored at one central site is False.
Each remote site must operate numerous instances of the database management system (or several DBMSs) in order to support a distributed database. Different types of distributed database settings can be distinguished by how closely these various DBMS instances collaborate with one another and whether there is a master site that manages requests involving data from numerous locations.
The fundamental element of distributed database architecture is that data should be kept at the locations where it will be accessed the most often (other important considerations are security, data integrity, and cost). A distributed database is organized by a data administrator in a crucial and central manner such that it is dispersed rather than decentralized.

Which of the following is a best practice to protect information about you and your organization on social networking sites and applications?
The best technique to prevent unauthorized access to your data is encryption. The process of converting data into a different format that can only be read by someone with access to a decryption key is known as encryption.
What is encryption?Data can be scrambled using encryption so that only authorized parties can decipher it. Technically speaking, it is the process of changing plaintext that can be read by humans into ciphertext, which is incomprehensible text.
In plainer terms, encryption changes readable data to make it seem random. A cryptographic key, or collection of numbers that the sender and the recipient of an encrypted message both agree upon, is needed for encryption.
Despite the fact that encrypted data appears random, encryption works in a logical, predictable manner, making it possible for someone who gets encrypted data and has the proper key to decrypt it and restore it to plaintext.
A third party is very unlikely to crack the keys used in truly safe encryption because they are complex enough.

When a computer enters the S3 state using hybrid sleep, the contents of memory are saved to disk, effectively indicating that the computer is in the S3 state but ready for the S4 state.
