Program Plan Intro
Data replication in a distributed system:
- In the distributed
database management, the main advantage is the availability of the system, so that the user who uses the data most, can avail it easily. - To make it possible, the distributed database system replicates the data in the database because in case one system fails, the data will available in another site.
Remote backup site:
- Remote backup site searches for the server 's content and takes backup of the data that could be used for future purposes in case of data failure or device crashes.
- Remote backup site avoids data loss by making a copy of data.

1.[30 pts] Computers generate color pictures on a video screen or liquid crystal display by
mixing three different colors of light: red, green, and blue. Imagine a simple scheme, with
three different lights, each of which can be turned on or off, projecting onto a glass screen:
We can create eight different colors based on the absence (0) or presence (1) of light
sources R,G and B:

Each of these colors can be represented as a bit vector of length 3, and we can apply
Boolean operations to them.
a. The complement of a color is formed by turning off the lights that are on and turning
on the lights that are off. What would be the complement of each of the eight colors
listed above?
b. Describe the effect of applying Boolean operations on the following colors:
Λ
1. Red(100) ^ Magenta(101)= Blue(001)
2. Bue(001) | Green(010)=
3. Yellow(100) & Cyan(011)=
