The statement "Microsoft’s answer to Netscape’s JavaScript language was .NET" is False. Microsoft's answer to JavaScript was actually JScript, while .NET is a more comprehensive software framework for application development.

The rivalry between Microsoft and Netscape in the late 1990s was an important moment in the history of the internet. Both companies were vying for dominance in the emerging world of web browsers and internet technologies. One of the key battlegrounds in this conflict was the development of programming languages that could be used to create dynamic, interactive web pages. Netscape had developed a popular language called JavaScript, which allowed web developers to create dynamic and interactive web pages. Microsoft responded with its own language called VBScript, which was similar in many ways to JavaScript but was only supported by Microsoft's Internet Explorer browser. However, Microsoft realized that it needed to create a more powerful and versatile language to compete with JavaScript, which led to the development of .NET. This new language was designed to be platform-independent, meaning that it could run on any operating system, and it was capable of supporting a wide range of programming languages.

Therefore, it is false to say that Microsoft's answer to Netscape's JavaScript language was .NET. While .NET was certainly a response to the growing popularity of JavaScript, it was not a direct replacement for it. Instead, .NET was a more comprehensive solution that aimed to provide a range of new tools and technologies for web development.

To switch between fibers, we use the "yield" function, which performs a context switch to the next fiber if there is one. This means that we return to the context of another fiber and resume executing it. Finally, we can terminate a fiber using the "terminate" function.

To make these functions work, we need to maintain a global queue of fibers using a list, which is updated as necessary.

The dividend yield reported on finance.yahoo.com is calculated as the annual dividend amount paid out by a company per share, divided by the current market price per share, expressed as a percentage. This is represented by the formula:

Dividend Yield = (Annual Dividend per Share / Current Market Price per Share) x 100%

For example, if a company pays an annual dividend of $2 per share and its current stock price is $50 per share, the dividend yield would be calculated as follows:

Dividend Yield = ($2 / $50) x 100% = 4%

This means that the company is paying out a dividend that is equivalent to 4% of its current stock price.

It's important to note that the dividend yield can fluctuate based on changes in the company's stock price or dividend payouts. Additionally, the dividend yield is just one factor that investors should consider when making investment decisions, as it does not take into account the company's financial health, growth prospects, or other factors that can affect the stock's value.

In contrast, the ratio of dividends to earnings (D/E) is a different metric that measures the amount of dividends paid out by a company relative to its earnings. It is calculated as follows:

D/E ratio = Dividends per Share / Earnings per Share

This ratio is used to evaluate a company's dividend policy and financial health. A high D/E ratio may indicate that a company is paying out a significant portion of its earnings as dividends, which could limit its ability to reinvest in the business or pursue growth opportunities.
