2. I have used if else and elif conditions to implement this code.

3. As, we were given to implement and execute the given requirements. I have used Linux commands to fulfill the requirements.

• CPU description

• Memory installed.

Hostnamectl -> is used to get the info of all the system name and domain name of Redhat as mentioned in the question

3. OS version and name:

OUTPUT: cat /etc/redhat-release -> contains all the info of OS version and name too..

Lscpu -> it contains the all the information related to CPU, name of CPU Architecture used in CPU etc

5. Memory installed.

Output:

lpstat -t -> it shows the list of printers configured to the system
