Answer:

Using CSMA/CD to avoid collision.

Explanation:

If the channel is detected idle then the station does not transfer the second frame to avoid the collision by design of the CSMA/CD (Carrier sense multiple access / Collision detection). When received the protocol for first frame, a station to send second frame begins at step 2 rather than step1.

Explanation :

• Station A and Station B are transfers data frames, remain all not want to transmit data. In this situation, station A find the channel to be idle and send first frame then next second frame.  

• Similarly B received the transfer data at the same time. Then leads to collision.  

• Using CSMA/CD to avoid collision.

Answer:

Group of answer choices.

A. Apply numbering to the list.

B. Apply bullets to the list.

C. Apply multilevel numbering to the list.

D. Manually enter a ">" character at the beginning of each item in the list.

Answer:

B. Apply bullets to the list.

Explanation:

Formatting is a feature found in a lot of word processing software applications such as Microsoft Word, Notepad, etc., which is designed to avail end users the ability to apply specific formatting options such as cut, bold, italics, underline, list, etc., to texts based on certain criteria defined by an end user.

Microsoft Word refers to a word processing software application or program developed by Microsoft Inc. to enable its users type, format and save text-based documents.

In Microsoft Word, a list can be formatted using a numbered or bulleted arrangement style. A numbered style (1, 2, 3, 4, etc) is typically used for an ordered list while a bullet is designed to be used for an unordered list.

Hence, the best way to format a document containing a list of items that appear in no particular order is to apply bullets to the list.

For example, a bulleted list of my favorite subjects arranged in no particular order would appear as this;

English language

Mathematics

Geography

Biology

Chemistry

Physics

Computer technology

You are working in a medium-sized company and are trying to convince your boss that you need to enter the global market. Your bo

What is global market and how does digital media play a role in the global market?

Several years back, it took you a couple of months to import products into a country or export goods to a market in another country. Doing so was tasking and only huge trading companies were able to take the risk. The emergence of global marketing involves conceptualizing and then conveying a final product or service worldwide, in different countries. Global marketing is more than just conceptualizing and selling a product worldwide. The whole process involves actual planning, production, placement, and promotion of a company’s product in a worldwide market.  

Digital media has and continues to offer brands greater opportunities than ever before to connect with global audiences. More recently, I.T, and particularly the internet, has shrunk the world further. Consumers can get products in a matter of days just by a click of a mouse button or businesses can have partners half a world away. With almost 2.5 billion active social media users worldwide, it makes sense for brands to find audiences through these channels.

Since the emergence of internet, even small to mid-sized firms are able to reach customers globally. With proper execution, globalization can bring many benefits into your organization.  

1. New Revenue Potential

Taking this business to new global levels will get us access to a much larger base of customers. If everything goes as planned, we will enjoy increased revenues and the company will be exactly the shot of life it needs to take its revenues to new heights.

2. Lower Budgeting Costs  

With a common messaging to be done, our marketing budget will be reduced significantly and will help maintain profit margins.  

3. Ability to Help More and More People.

The solutions this company offers without a doubt has a potential to help customers all over the world improve their lives in some way. It will be able to help an exponentially greater number of people find answers to new challenges this company is able to solve.

Despite having many advantages of global marketing, it begs the question, what is that one challenge the company will face if it moves into a global market? Although we may have internet, nothing is able to beat our personal presence to our prospects and distribution partners. Not to mention the costs related to logistics, at some point, we will have to figure out the costs of doing long distance business in other regions of the world.

There are major disadvantages of global marketing

1. Cultural Barriers

Not every culture will be suitable for the products that our company offers. Crossing these cultural barriers might be cumbersome and very expensive for the company. We might have to adapt to certain rules that govern specific countries.

2. Inventory Management

If we are not careful, huge unused stocks may pile up and this may happen due to under or overestimation of projections or launching in a hurry without proper market research.  

3. Product Customization

We may be required to have a bigger budget that will enable us customize our products. Product customization will take us extra time to implement. Without sufficient marketing, this might be hard to achieve.

What role does modern technology play in globalization today?
lana [24]

<span>Advances in technology are one of the main reasons that globalization has escalated in the past decade. In information and communication technology, innovations have become smaller in size, more efficient and often more affordable. In transport technology, vehicles have tended to become larger and faster, as well as becoming more environmentally friendly and cheaper to run. Whether for personal use or for business, technology has made the world seem a smaller place and assisted in the rise of globalization. </span>
