PART – 3
III. Explain in Brief

Question 1.
Analyze Why the drives are segregated?
Answer:
Advantages of partitioning the drive:
Better organize your data :
Partitioning a hard disk will provide us with several separate logical drives. Hence, in this way, we will be able to organize our data on every partition much more precisely.

Run different operating systems on one PC :
If you desire to run several different operating systems on your computer, having separate drive partitions is mandatory in this case. It is because every operating system demands an independent partition for its own.

Reduce the threats of data loss :
There are multiple potential threats around our computer, such as virus infection, hardware failure, software malfunctions and so on. Therefore, we have at least two partitions on one PC, one for the operating system and one for personal data. In this case, even when we need to reinstall the operating system, our personal data will remain intact.

More convenient for backup and restore
It will be much easier to back up all the partitions separately than to back up a whole disk.

Improve performance
The hard disk will be able to work better on small chunks of data rather than one large drive.

Question 2.
If you are working on multiple files at a time, sometimes the system may hang.
What is the reason behind it. How can you reduce it?
Answer:
When we open multiple applications, each application opened on the system takes some internal and hardware resources to keep it running. Memory is used by all the applications. System processing speed will be shared and it will become slow finally the system will hang.

Methods of reducing it:

  1. It is advisable to run one program at a time.
  2. Upgrade RAM
  3. Clean the cache Memories
  4. Defragmentation can be done

Question 3.
Are drives such as hard drives and floppy drives represented with drive letters? If so why, if not why?
Answer:
Yes. Drives such as hard drives and floppy drives represented with drive letters.

Generally, A, B: drives are assigned for floppy drives. C: is fixed for Hard Disk. D: is for the next partition or another hard disk. E; and F: also can be another hard disk or another partition of the same hard disk or partition on the second hard disk.

D: or E; can be used for CD/DVD drives. We can use the last drive letter upto Z; for mapping a drive letter for other programming purposes.

Also generally F: arid above drive letters are j used for network mapping purposes.

Question 4.
Write the specific use of Cortana.
Answer:
Uses of Cortana:

  1. Cortana is a voice-activated personal assistant.
  2. Give the reminders based on time, places, or people.
  3. Track packages, teams, interests, and flights.
  4. Send emails and texts.
  5. Manage the calendar and keeps it up to date.
  6. Create and manage lists.
  7. Chit chat and play games.
  8. Find facts, files, places, and info.
  9. Open any app on the system.

Question 5.
List out the major differences between Windows and Ubuntu OS.
Answer:

  1. Ubuntu supports high security than windows.
  2. Windows is more user friendly than Ubuntu
  3. Ubuntu is a free and open-source-based Linux OS whereas windows is a closed source and it is not free.
  4. Ubuntu uses a Linux kernel whereas windows use a hybrid kernel.

Question 6.
Are there any difficulties you face while using Ubuntu? If so, mention it with reasons.
Answer:
Yes. There many difficulties we face while using Ubuntu.
The following are some of them.

Different desktop managers lead to a fragmented experience
If a user seeking help says they are on Ubuntu, you cannot be sure that they are on Unity -¬they may be on KDE, Gnome or something else which ultimately can lead to confusion.

Too many package managers make Linux hard to learn and master
New Linux users will think the apt package manager is the only package manager. There are many other managers such as YUM and Pacman. These package managers use entirely different commands which can be confusing.

Lack of software
Linux users will eagerly point you to wonderful alternatives that can be acceptable. Need Adobe Photoshop? Use Gimp. Need Microsoft Office? Use LibreOffice. For basic users, these alternatives may work. However, true professionals cannot trust their careers and reputations to alternative software.

Hardware compatibility
Hardware will be released after that kernel release and some accessory hardware will not have the needed software to the interface.

Question 7.
