I think (a) is the answer because this is the screen that it should open when u use it
So I am able to print my math notes and keep up in geometry.
Doubly linked chain
When a linked chain contains nodes that reference both the next node and the previous node, it is called a doubly linked chain. This type of chain is often used in data structures because it provides a way to easily traverse the data in both directions. However, because each node must reference both the next node and the previous node, doubly linked chains require more memory than singly linked chains.

Answer:
Explanation:
With an anti-virus, we can search, detect, and delete malware like spyware, worms, Trojans, rootkits, pseudoviruses, etc.
An anti-virus can detect virus with several methods like:
- Digital signature
- Heuristic detection

Is necessary for personal laptops and desktops, even in companies hardware.
Answer: In operating system a code segment which accesses some shared variables or resources one at a time atomically such other no other code or process is accessing that resource or variable at the same time.
Entry section code block allows the access to the shared resource or variable and exit section code signals the termination from access to the shared resource or variable.
Explanation:
Entry and exit section codes needs to check certain properties before allowing the access and removal of access to a particular code segment.
These conditions are:
1. Bounded waiting.
2. Mutual exclusion.
3. checking thread execution status to allows other threads to enter the critical section (CS).
