Question 1: what's the deal with collaborations as a network application?

Answer:

The third major category of network applications is collaboration. Collaboration refers to efforts by two or more entities-that is, individuals, teams, groups, or organizations-who work together to accomplish certain tasks. The term workgroup refers specifically to two or more individuals who act together to perform a task.Workflow is the movement of information as it progresses through the sequence of steps that make up an organization's work procedures. Workflow management makes it possible to pass documents, information, and tasks from one participant to another in a way that is governed by the organization's rules or procedures. Workflow systems are tools for automating business processes.If group members are working in different locations, they constitute a virtual group (team). Virtual groups conduct virtual meetings-that is, they "meet" electronically. Virtual collaboration (or e-collaboration) refers to the use of digital technologies that enable organizations or individuals who are geographically dispersed to collaboratively plan, design, develop, manage, and research products, services, and innovative applications. Organizational employees frequently collaborate virtually with one another.Some organizations collaborate virtually with customers, suppliers, and other business partners to become more productive and competitive.Collaboration can be synchronous, meaning that all team members meet at the same time. Teams may also collaborate asynchronously when team members cannot meet at the same time. Virtual teams, whose members are located throughout the world, typically must collaborate asynchronously.Although a variety of software products are available to support all types of collaboration, many organizations feel that too many software tools are being used in collaborative efforts. These firms want a single place to know what was shared, who shared it with whom, and when. Firms also want smarter

collaboration tools that are capable of anticipating workers' needs.Collaborative software products include Google Drive (http://drive.google.com), Microsoft Office 365 Teams (https://www.microsoft.com/en-ca/microsoft-365/microsoft-teams/group-chat-software). In general, these products provide online collaboration capabilities, workgroup email, distributed databases, electronic text editing, document management, workflow capabilities, instant virtual meetings, application sharing, instant messaging, consensus building, voting, ranking, and various application-development tools.Crowdsourcing: One type of collaboration is crowdsourcing, in which an organization outsources a task to an undefined, generally large group of people in the form of an open call. Crowdsourcing provides many potential benefits to organizations. First, crowds can explore problems-and often resolve them-at relatively low cost, and often very quickly. Second, the organization can tap a wider range of talent than might be present among its employees. Third, by listening to the crowd, organizations gain firsthand insight into their customers' desires. Finally, crowdsourcing taps into the global world of ideas, helping companies work through a rapid design process. Let's look at some examples of crowdsourcing.IdeaBOOST (www.ideaboost.ca) is an innovative and creative business development lab sponsored by the Canadian Film Centre that uses crowdsourcing to help Canadian entertainment entrepreneurs grow ideas into products and concepts into businesses. The website serves as a platform where ideas are submitted, and based on the audience's response, the highest rated ideas are shortlisted. The chosen contestants spend four months working with industry-leading mentors to define their business model and to develop a market-ready prototype.

Question 2: what are the different ways you can access the internet?

Answer:

You can also access through an internet service provider. ISP's connected together through Network Access Points. They determine how traffic is routed.

Question 3: why are networks so important?

Answer:

In addition to networks being essential in your personal lives, there are three fundamental points about network computing you need to know. First, in modern organizations, computers do not work in isolation. Rather, they constantly exchange data with one another. Second, this exchange of data-facilitated by telecommunications technologies-provides companies with a number of very significant advantages. Third, this exchange can take place over any distance and over networks of any size.Without networks, the computer on your desk would be merely another productivity-enhancement tool, just as the typewriter once was. The power of networks, however, turns your computer into an amazingly effective tool for accessing information from thousands of sources, thereby making both you and your organization more productive. Regardless of the type of organization (profit/not-for-profit, large/small, global/local) or industry (manufacturing, financial services, health care), networks in general, and the Internet in particular, have transformed-and will continue to transform-the way we do business.Networks support new and innovative ways of doing business, from marketing to supply chain management to customer service to human resources management. In particular, the Internet and

private intranets-a network located within a single organization that uses Internet software and TCP/IP protocols-have an enormous impact on our lives, both professionally and personally.For all organizations, regardless of their size, having a telecommunications and networking system is no longer just a source of competitive advantage. Rather, it is necessary for survival.Computer networks are essential to modern organizations for many reasons. First, networked computer systems enable organizations to become more flexible so they can adapt to rapidly changing business conditions. Second, networks allow companies to share hardware, computer applications, and data across the organization and among different organizations. Third, networks make it possible for geographically dispersed employees and workgroups to share documents, ideas, and creative insights.This sharing encourages teamwork, innovation, and more efficient and effective interactions. Networks are also a critical link between businesses, their business partners, and their customers.Clearly, networks are essential tools for modern businesses. But why do you need to be familiar with networks? The simple fact is that if you operate your own business or you work in a business, then you cannot function without networks. You will need to communicate rapidly with your customers, business partners, suppliers, employees, and colleagues. Until about 1990, you would have used the postal service or the telephone system with voice or fax capabilities for business communication. Today, however, the pace of business is much faster-almost real time. To keep up with this incredibly fast pace, you will need to use computers, email, the Internet, smartphones, and other mobile devices.Furthermore, all of these technologies will be connected through networks to enable you to communicate, collaborate, and compete on a global scale.Networking and the Internet are the foundations for commerce in the twenty-first century. Recall that one key objective of this book is to help you become an informed user of information systems.Knowledge of networking is an essential component of modern business literacy.

Question 4: what are WAN's?

Answer:

When businesses have to transmit and receive data beyond the confines of the LAN, they use wide area networks. The term wide area network did not even exist until local area networks appeared.Before that time, what we call a wide area network today was simply called a network.A wide area network (WAN) is a network that covers a large geographical area. WANs typically connect multiple LANs. They are generally provided by common carriers such as telephone companies and the international networks of global communications services providers. Examples of these providers include Bell Canada (www.bell.ca) and Rogers Communications (www.rogers.com), AT&T (www.att.com) in the United States, Deutsche Telekom in Germany (www.telekom.com), and NTT Communications (www.ntt.com) in Japan.WANs have large capacities, and they typically combine multiple channels (e.g., fibre-optic cables, microwave, and satellite). WANs also contain routers-a communications processor that routes messages from a LAN to the Internet, across several connected LANs, or across a WAN such as the Internet. The Internet is an example of a WAN

Question 5: A common LAN protocol is Ethernet. Many organizations use 100-gigabit Ethernet, through which the network provides data transmission speeds of 100 gigabits (100 billion bits) per second. The 400-gigabit Ethernet is the latest standard for high speed network communications based on Ethernet protocol

Question 6: What's the deal with communication as a network application?

Answer:

Email: Electronic mail (email) is the largest-volume application running over the Internet. Studies have found that almost all companies conduct business transactions through email, and the vast majority confirm that email is tied to their means of generating revenue. At the same time, however, the amount of email that managers receive has become overwhelming. The problem is that too much email can actually make a business less productive.Web Based Call Centres: Effective personalized customer contact is becoming an important aspect of web-based customer support. Such service is provided through web-based call centres, also known as customer care centres. For example, if you need to contact a software vendor for technical support, you will usually be communicating with the vendor's web-based call centre, using email, a telephone conversation, or a simultaneous voice and web session. Web-based call centres are sometimes located in foreign countries such as India. Such offshoring is an important issue for Canadian companies. (We discuss offshoring in Chapter 13.) Significantly, some companies are moving their call centre operations back to their country of origin for several reasons. First, they believe they have less control of their operations when the centres are located overseas. They must depend on the vendor company to uphold their standards, such as quality of service. A second difficulty is language differences, which can create serious communication problems. Third, companies that manage sensitive information risk breaching customer confidentiality and security. Finally, the call centre representatives typically work with many companies. As a result, they may not deliver the same level of customer services that each company requires.Electronic chat refers to an arrangement in which participants exchange conversational messages in real time in a chat room. Chat programs allow you to send messages to people who are connected to the same channel of communication at the same time as you are. Anyone can join in the conversation.Messages are displayed on your screen as they arrive.There are two major types of chat programs. The first type is web based, which allows you to send messages to Internet users by using a web browser and visiting a web chat site (e.g., Facebook online messenger www.facebook.com/messenger/). The second type is email based (text only). It is called Internet Relay Chat (IRC). A business can use IRC to interact with customers, provide online experts for answers to questions, and so on.Telecommuting: Knowledge workers are being called the distributed workforce, or "digital nomads." This group of highly prized workers is now able to work anywhere and any time, a process called telecommuting. Distributed workers are those who have no permanent office at their companies, preferring to work in home offices, in airport lounges or client conference rooms, or on a high school stadium bleacher. The growth of the distributed workforce is driven by globalization, extremely long commutes to work, ubiquitous broadband communications links (wireline and wireless), and powerful
