Chapter 4, Problem 43SG
Explanation of Solution
Management tools: File, disk and system management tools are used in order to protect and manage a computer, the devices connected to it and the software. Some of the types of file, disk and system management tools are as follows:
File manager:
- File manager application helps to organize files and folders which helps the users to find any program easily.
- Here, the files and documents gets stored in a folder where the user can name it accordingly.
Search tool:
- It is a tool that helps to find a file, application, contacts, and so on that is store on a computer or a mobile device.
- This tool is also located in music player application where the users can search for specific music.
Image viewer:
- It is a tool which is present in many operating systems.
- It allows people to view, copy, share, and print the image files like GIF images, and photos.
- This tools also allows people to edit images.
Uninstaller:
- A program that is used to remove an application or software from the computer is called as uninstaller.
- It deletes all the files and folders from the drive and also it deletes all the program entries from the system files.
Disk cleanup:
- It is a tool that is used to remove unwanted files and folders from the computer.
- The unwanted files may be deleted files, unused files, temporary Internet files, and so on.
Disk defragmenter:
- It is the process of re-organizing the disk that makes sure that the files are stored in continuous sectors.
Operating system contains disk defragmenter.- This process is required only on hard-disks...

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)=
