Apple TV vs Roku

An Apple TV is a small-sized black plastic box that connects to your television set via an HDMI cable and connects to your home wireless network. It gives users access to Internet videos from the comfort of their homes. It has a three buttoned remote control and streaming is enhanced extensively from Netflix to youtube as well as all online video applications. On the other hand, ROKU is a streaming device that provides over the top media services in the form of video channels by receiving data through a high-speed internet connection. From their definitions, one can easily confuse the two because they seem to serve the same purpose but they have different features. You get what you pay for and that is what makes the difference between the two products.
Firstly, considering the interface setup, Apple TV is better than Roku in nearly everything. It’s faster, more complete, and it provides a better overall experience. In comparison to Apple tv, the Roku has a better remote control and it has a lower price. Roku also doesn’t offer large storage like the Apple TV, which does allow you to store many applications such as movie apps and games.their speed is determined by RAM and processor, therefore, the Apple TV is faster than the Roku Ultra.
Secondly, these products have similarities in that they do offer three-dimensional audio provided that you have a sound system that supports this protocol. They both have high-quality mainstream content and services like HULU, Amazon, and Netflix. Lastly, you will find that both products are solid streaming devices, but the one that you choose depends on the amount of money you are willing to spend. In conclusion, Apple is expensive but they serve the same purpose so the choice of customers doesn’t limit them to enjoy their favorite shows.

Types of URLSession tasks in iOS

Within a URLSession, we create tasks that currently upload data to server or retrieve data from server. The URLSession API provides three types of tasks.

  1. Data tasks: Data tasks send and receive data using NSData objects. They are intended for short and often interactive requests to server.
  2. Upload tasks: Upload tasks are similar to data tasks in addition they send data and enable upload when the app isn’t running.
  3. Download tasks: Download tasks are similar to data tasks in addition they retrieve data and enable download when the app isn’t running.

Limitations of URL shared session in iOS

There are quite a few limitations while using shred URL session and they are as follows:

  • You can’t obtain data incrementally as it arrives from the server.
  • You can’t customize the connection behaviour.
  • Your ability to perform authentication is limited.
  • You can’t perform background downloads and uploads when your app isn’t running.

If our app uses, cache, cookies, custom network protocols or authentication, it is better to avoid URL shared session.

URL shared session in iOS

For basic requests, URLSession class provides a shared singleton object to perform default behaviour for creating tasks. We can use this object to fetch data to memory with few lines of code.We don’t create a shared session like other URLSessions, we can access this directly by using its property.



Types of URLSession in iOS

URLSessions are responsible for sending and receiving  HTTP requests. Tasks within the given URL system share a common configuration object, which defines connection behaviour like maximum number of allowed connections, whether to allow connections to cellular network and so on. iOS provides us with the following types of URLSessions for us to enable data transfer.

  • URL Shared session
  • URL default session
  • URL ephemeral session
  • URL background session


URLSession in iOS

The URLSession class and related classes provide an API for downloading data from and uploading data to endpoint indicated by URLs. The API allows our app to perform background downloads when app isn’t running or it is in suspended state.
