Operating System (OS): The most important program that runs on a computer is operating system. OS is the term that acts as an interface between the hardware and the user. It is the first program loaded into the computer memory whenever the computer starts up. It is responsible for the management to co-ordinate the activities on a computer system. OS does basic operations such as getting input from the keyboard, displaying output in the monitor and monitoring the files. OS controls the peripheral devices like printers, hard drives and mouse. The responsibilities of OS are bound to get higher when it comes to security, because it provides the access rights for users.

Question

(Short-answer) b. Continue from the previous question. Suppose part of the data you extracted from the data warehouse is the following. Identify the missing values you think exist in the dataset. Use Column letter and Row number to refer to each missing value in the dataset. Please write down how you want to address each particular missing value (you can group them if they receive same treatment). For imputation, you do not need to calculate the exact imputed values but just describe what kind of value you want to use to impute.
