When a customer makes an inquiry about a book, the system first checks the availability of the book. If the book is available then the customer needs to validate him/herself. If a book is unavailable, the system shows an error message to the customer and also saves the list of unavailable books in a file. If a customer fails to validate him/herself, can register into the system and issue a book. For valid customers, the number of books issued to him is checked. If the maximum quota exceeds then an error message is shown to the customer. Otherwise the book is issued to the customer. After issuing the book the system updates the database and prints a receipt. In this way customers can receive the book. Please Draw a Activity diagram based on the above scenario.You have a Linux system that has a 1000GB hard disk drive, which has a 90GB partition containing an ext4 filesystem mounted to the / directory and a 4GB swap partition. Currently, this Linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. The database application and the associated data will take up over 200GB of hard disk space. In addition, these 100 users will store their personal files on the hard disk of the system. Each user must have a maximum of 5GB of storage space. The department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. How much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? Where would these partitions be mounted? What quotas would you implement? What commands would you need to run and what…
