Provide examples from your own experience to support your ideas.
Answer:
Make the importance of effective communicationWork with HR to develop new Skills expectations and rolesMaking Oral ReportsUsing the TelephoneGive Direction and FeedbackExplanation:
Good communication skill is the most important skill for having a good relationship with business and that is why nowadays companies are making it must-have skill for every IT employee. They are also including it into performance appraisals so that way employees are giving it a topmost priorityCompanies are creating the jobs having titles such as "technology relationship manager", "IT Business Analyst" and "business technology specialist" where the titles suggest that the main focus of such titles is IT-Business relationship. One another way companies are trying to adopt is moving IT employees temporary for some time in business so that they can learn the business and enhance the relationship with them. You will need to make oral reports to other staff, such as the executive chef or restaurant manager. For example, you might have to report on the condition of some equipment or explain your actions regarding a problem with a restaurant supplier. You will also need to make oral reports to people who work under you, such as apprentices or salad preparation staff. For example, you might have to explain the preparation of a new menu item. An effective oral report has the same parts as an effective written report, namely an introduction, a body (or explanation), and a conclusion. Communicating on the telephone can be more difficult than speaking in person because many of the non-verbal cues are missing. When dealing with guests and other outsiders, it is particularly important to create a good first impression of your business. This first impression is created almost solely by your voice. For example, if you pick up the phone and bark “Yo” into the receiver, the caller is likely to be put off by your offhand manner and tone of voice. The caller may wonder whether he or she has reached the right number.A form of oral report that you will have to make if you supervise other people feedback on others’ performance. Feedback can be constructive or destructive. As these words imply, only constructive feedback serves any useful purpose. Take an example where the apprentice under your supervision is making pastries. Destructive feedback would be, “Are you stupid or something? The oven needs to be preheated before you put the pastries in to bake!” Do not use blaming words or indulge in name calling (“You are so…”). When people feel blamed, they often tune out of the discussion and do not hear your positive suggestions for improvement.Which of the following statements is true?

is the abstraction of web-based computers, resources, and services that system developers can utilize to implement complex web-based systems
Answer:
Cloud computing
Explanation:
Cloud computing is a network of resource servers on the internet, used by individuals or a corporation to store and access data. This platform helps reduce the cost of installing and managing a data center, but allows the use of the resources based on subscription if the organization. It promotes a central access of resources, since all the data are stored in a place.
System developers take advantage of cloud computing with all it's resources to expand the services within managed networks.
The question pertains to the strategies and methodologies used by developers to build complex web-based systems, specifically through the use of web services, virtual servers, and Service-Oriented Architecture (SOA). These abstractions enable the scalable and efficient development of web applications.
Explanation:The abstraction of web-based computers, resources, and services that system developers can utilize to implement complex web-based systems refers to a collection of strategies and methodologies that allow for the efficient development, deployment, and maintenance of web applications and services. This includes the use of web services, virtual servers, and architectures like Service-Oriented Architecture (SOA) to facilitate the interaction between disparate services over the internet. Developers leverage these abstractions to build scalable, robust applications that can interact seamlessly with other web services, manage resources dynamically, and adapt to changing demands without the need for constant redesign.
Specifically, web services enable applications to offer their APIs over the web, allowing for the integration of various services such as booking systems, payment processing, and content delivery. Virtual servers abstract physical hardware resources, allowing multiple virtual systems to operate independently on a single physical server, which optimizes resource utilization and can reduce costs. SOA, on the other hand, provides a framework for building applications that can easily communicate with each other, making it easier to integrate new features or services without significant disruptions to existing systems.

What is the term for the intentional search for information about others' feelings to help explain the meaning of uncertain circumstances and events?
Answer: Social referencing.
Explanation:
Social referencing is the process whereby infants use affective display of an adult to regulate their behaviors.
Most likely occurs when a situation breeds uncertainty. For instance, If a child receives conflicting messages from their mother and father, the child becomes quite upset.
The term for intentionally seeking information about others' feelings to understand uncertain situations is called social referencing. It is a key component of social cognition and often involves using emotional cues from others to guide one's behavior in uncertain scenarios.
Explanation:The term for the intentional search for information about others' feelings to help explain the meaning of uncertain circumstances and events is known as social referencing. This concept refers to the process by which individuals look for information from others to clarify a situation. People often use the emotional expressions of others as a source of information to make decisions about their own behavior when they are faced with ambiguous or uncertain circumstances. This dynamic becomes even more complex during social interactions because individuals are simultaneously seeking and providing cues to one another, which can be influenced by variables such as social group stereotypes or personal simulation of reactions in similar situations.
Social referencing is part of social cognition, a field in social psychology that focuses on how we think about others and the social world. This can involve processes like simulation, where we imagine what we would feel in another person's situation, or projection, where we assume others share our thoughts and emotions. However, relying too much on projection can lead to egocentrism and inaccuracies in social perception, as we may overestimate the similarity of other people's mental states to our own.
