Negotiation involves discussions between parties to reach a mutually acceptable solution to conflicts or disputes, often leading to a win-win outcome and preserving the customer relationship.

Logical reasoning involves the systematic analysis and evaluation of arguments or claims to determine their validity. It requires assessing the consistency and coherence of reasoning and evidence presented. This process helps individuals make sound judgments and decisions based on logical principles.

A project plan typically includes various components such as scope, budget, risk management, and stakeholder communication. These components help in outlining the project's objectives, resources, and strategies to achieve success.

Critical thinking is a skill that can be cultivated and developed through practice, education, and exposure to diverse perspectives. While some individuals may have a predisposition towards critical thinking, everyone can improve their critical thinking abilities through conscious effort and learning.

A Process ID (PID) is a unique numerical identifier assigned to each process running in an operating system. It allows the operating system to keep track of and manage individual processes, including allocating system resources, scheduling tasks, and terminating processes when necessary.

Adaptability refers to the ability to adjust to new conditions or changes. It involves being open to new ideas and being willing to learn new skills, which are essential qualities in today's dynamic work environments.

A risk register is a document that contains comprehensive details about identified risks. It should provide specific information about each risk to ensure effective management. Option 3 is therefore correct.

Processes are instances of a program in execution, whereas threads are lightweight processes within a process. Threads share memory and resources with other threads of the same process, leading to efficient multitasking.

In professional communication, clarity and transparency are paramount. Using clear and concise language helps ensure that the message is easily understood by all recipients, regardless of their background or expertise. Technical jargon should be avoided, as it may alienate non-technical employees and hinder understanding. Providing vague information can lead to confusion and misunderstanding, undermining the purpose of the email. Similarly, using humor may not be appropriate in this context, as it can detract from the seriousness of the policy change and potentially offend some employees.

Active listening is a critical communication skill that involves fully concentrating on what is being said by the speaker. It goes beyond simply hearing words and entails understanding the speaker's message, asking clarifying questions, and providing appropriate feedback. Active listening requires attentiveness, empathy, and engagement to ensure effective communication and mutual understanding between the speaker and the listener. By actively listening, individuals can build stronger relationships, resolve conflicts, and enhance their overall communication proficiency.

A switch is a networking device that operates at the data link layer (Layer 2) of the OSI model. It connects devices within a local area network (LAN), using MAC addresses to forward data to the correct destination. Unlike hubs, switches can identify the intended recipient of the data and send it only to that device, reducing unnecessary network traffic. Switches are crucial for modern Ethernet networks as they improve network performance and security.

Handling the unexpected risk of a critical vendor going bankrupt requires immediate action to minimize disruption to project delivery. By quickly identifying alternative vendors and establishing backup plans, the project manager can ensure that the project continues as planned with minimal impact. Informing stakeholders about the situation and reassuring them demonstrates transparency and helps maintain stakeholder confidence in the project's ability to overcome challenges.
