Assumptions Made by Local Broadband Speed Tests

A lot of websites provide broadband speed tests, which are available free of cost. People use these online broadband speed tests to know if they are getting the speed that they pay for. There are hundreds of speed tests available as many ISPs provide them, but not all of these services give accurate results. If you use two websites to check your connection speed in different browser windows on your PC, the result might not be the same. There are many ways in which the speed test could give inaccurate results. This article discusses a few reasons these tests are not accurate. These are the wrong assumptions of these broadband speed test services, which lead to the wrong result.

First Incorrect Assumption

The first assumption which leads to the wrong calculation is the size of the downloaded file to calculate the download speed. A 5 KB file means 512,000 bits, whereas many service providers and testing tools might assume that the 5 KB file is of 500,000 bits. It leads to the wrong calculation of the download speed. It is why you should always choose a speed test service such as PTCL speed test to get accurate results.

Second Incorrect Assumption

Many services measure the download speed by assuming that it starts immediately when the user presses the “start” or “go” button. They calculate the download time from the moment the user presses the button. It is the reason that they get wrong results. Services must understand that there is always an initial delay because of the time the website takes to send a request to download the file from the server.

Third Incorrect Assumption

Assuming that using JavaScript to measure the start and end of the download will work accurately is wrong. This assumption leads to inaccurate results. As the JavaScript runs on the user’s computer and not on the web server, there is a difference in the clocks of both computers, which results in inaccurate speed test results.

Thus, make sure that you choose a reliable speed test service.

Implementation of iOS setting using preferences

In iOS, the Foundation framework provides the low-level mechanism for storing the preference data. Apps then have two options for presenting preferences those are displaying preferences inside the app and using a setting bundle to manage preferences from the Settings app. Which option you choose depends on how you expect users to interact with preferences. The Settings bundle is the preferred mechanism for displaying preferences. However, games and other apps that contain configuration options or other frequently accessed preferences might want to present them inside the app instead. iOS developers can implement that.

Settings bundle contains files that describe the structure and presentation style of your preferences. The Settings app uses this information to create an entry for your app and to display your custom preference pages. The Settings app implements a hierarchical set of pages for navigating app preferences. The main page of the Settings app lists the system and third-party apps whose preferences can be customized. Selecting a third-party app takes the user to the preferences for that app. Every app with a Settings bundle has at least one page of preferences, referred to as the main page. If your app has only a few preferences, the main page may be the only one you need. If the number of preferences gets too large to fit on the main page, however, you can create child pages that link off the main page or other child pages. There is no specific limit to the number of child pages you can create, but you should strive to keep your preferences as simple and easy to navigate as possible.

The contents of each page can consist of one or more controls that you configure. You could try this out. Following content will lists the types of controls supported by the Settings app and describes how you might use each type.

Text field: The text field type displays a title and editable text field. You can use this type for preferences that require the user to specify custom string value.

Title: The title type displays a read-only string value. You can use this type to display read-only preference values.

Toggle switch: The toggle switch type shows an ON/OFF toggle button. You can use this type to configure preference that can have only one of two values. Although you typically use this type to represent preferences containing Boolean values, you can also use it with preferences containing non-Boolean values.

Slider: The slider type displays a slider control. You can use this type of preference that represents a range of values. The value of this type is a real number who’s minimum and maximum value you specify.

Multivalue: The multivalue type lets the user select one value from a list of values. You can use this type for a preference that supports a set of mutually exclusive values. The values can be of any type.

There is more control that can be used for implementing the ios app development process.
