Answer:
Network scan
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.
Generally, a security assessment is carried out by network security experts on a regular basis to determine potential loopholes or vulnerabilities in the information and technology (IT) infrastructure. One of the techniques or approach used in security assessment is a network scan.
A network scan is a security assessment technique used for the automatic detection of host systems on a network. Although a network scan isn't capable of discovering or detecting all the weaknesses on a network, it avails users information about the computer systems that are active on the network and what services the computer systems offer or what ports are available on them.

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).

Explanation:
The full form of SDLC is System Development Life Cycle, Which tells the rules and processor which have to follow by any software developer. It gives the benefits to make the error-free software.
Another option is invalid because--
- Option a tells that the SDLC is a method but it is a formal processor.
- Option b tells that the SDLC is a framework but it is not any framework it is a guideline.
- Option d tells that the collection of theorems that are used to change in software projects but it is only the model, not any theorems.
