Answer: Memory hierarchy is the hierarchy that is created on the basis of the response time of different memories. The performance obtained by the memory helps in creating a computer storage space in distinguished form. The factors considered for the creating of the hierarchy structure are usually response time, storage capacity, complexity etc.
Usage of different kind of memories take place due to different kind of requirements from the system which cannot be fulfilled using one memory device.The requirement is based on saving time, decreasing complexity , improving performance etc.Example of requirements can be like some functions and files do not require much space , some might require quick accessing,etc.
Thus hierarchy of any particular system is in the form of fast to slow order from registers,cache memory, Random access memory(RAM) and secondary memory.

Answer:
Resources
Explanation:
Carlie certainly requires to review the resources. It is important to find out how many software engineers, testers, etc. are available. And only then Carlie can find out the exact deadlines as required here. And hence, she must have look at the resources while determining the specific deadlines. Hence, resources are the correct option.
Answer:
The output is "<class 'str'> ".
Explanation:
In the given python code a print() function is defined. Inside this function, a type() function will use, in which a numeric value is passed in the double quotes (" ") as a function parameter. Double quotes are normally used for print value as a message but in this code, value is not printed because we use the type() function.
- The type() function Returns the parameter class type of the argument(object).
- This function is used for debugging. In this function, we pass a single parameter that will return the type of given object.
Answer: Safety effort of system is defines as the measures that are taken to provide and maintain the protection of the system.There are several methods ,tool and efforts made for the system security .Benefits of the system security are as follows:-
- Takes control over the hazardous situation and maintain the security
- System security will also increase the development of the system easily.
- Approach towards the analyzing of the system function
- Data, information and functions are safe from being detected in unauthorized way.
- Functions and implementation is made easy without the fear of getting attacked or hacked.
