Anandi has been working with Excel to record data from an extensive physics experiment at her university. She has hundreds of columns representing different trials, and many rows showing different pieces of data from each trial. A
handful of cells have data that stand out, so she needs to show them to her professor, even though these cells are
hundreds of columns apart.
If Anandi has written down the names of those cells, what is the fastest way to get to these cells while in Excel?
dragging the scroll box and trying to find the needed cells
pressing the arrow keys until each appropriate cell is active
holding the shift key while typing in the addresses of all cells
pressing Control + G and typing in the address of each needed cell

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 entries to /etc/fstab would you need to create? justify your answers.
