  Performance tuning:

  • Performance tuning improves the performance of the system.
  • It helps in increasing the volume of the data which can be processed quickly.
  • Also, performance of the system depends on how much load any system can hold.
  • Hence performance tuning refers to increasing the load of the system without any decrease in performance.
  • Thus performance tuning refers to change the original system in a way that it can take more load with the same performance.

  Hardware tuning:

  • For viewing the performance of the system, many things are taken into consideration.
  • Hardware plays an important role in performance of the system.
  • Therefore, hardware tuning refers to the change in the hardware devices of the system so that the after changing it, the performance must be improved.
  • The hardware tuning can be implemented by increasing hardware capacity, hardware processing speed or any other performance factors.

  Transaction tuning:

  • Transaction refers to performing various actions of data accessing, data size, data form that is how the data is stored.
  • Transaction tuning refers to change in the data related tasks so that it can be done for efficiently than original one.

Create 6 users: Don, Liz, Shamir, Jose, Kate, and Sal. Create 2 groups: marketing and research. Add Shamir, Jose, and Kate to the marketing group. Add Don, Liz, and Sal to the research group. Create a shared directory for each group. Create two files to put into each directory: spreadsheetJanuary.txt meetingNotes.txt Assign access permissions to the directories:  Groups should have Read+Write access Leave owner permissions as they are  “Everyone else” should not have any access   Submit for grade: Screenshot of  /etc/passwd contents showing your new users Screenshot of /etc/group contents showing new groups with their members Screenshot of shared directories you created with files and permissions
