Question Discussion & Solution

Concept:-

 Single linked list:

This list consists of a number of nodes in which each node has a next pointer to the following element. The link of the last node in the list is NULL, which indicates the end of the list.

Calculation:-

After perform ((Start → Next) → Next) the current link transfer to the third node of linked. And Third node data value is 128.

Hence the correct answer is 128.

Explanation:

Bus: In computer architecture, a bus (related to the Latin “omnibus”, meaning “for all”) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.

The types of buses are:

Address Bus:

• It is a unidirectional Bus, which is responsible for only one-way communication.

Data Bus:

• It is a bi-directional bus.
• Data and Instructions pass through this bus to reach the microprocessor.
• This is responsible for the exchange of information between the main memory and microprocessor.

Control Bus:

• This is a unidirectional bus.
• This tells whether read or write, which operation should be performed that is in which direction the data should flow.

So Utility Bus is not a type of bus used in computer architecture, hence option 4 is the correct answer.

(E_Name, Salary_in_Lakhs) is the key

(E_Name, Salary_in_Lakhs) → {E_ID, E_Age, E_mail}

E_Name: Nitesh is repeated

Check only for Nitesh

(Nitesh, 9) → (XE005, 24, nitestSE@123)

(Nitesh, R) → (XE023, 24, nitestCE@123)

Since right hand side is not same

Therefore, R cannot be equal to 9
