Question 1:
What is the difference between USB-C and USB 3.1?
Question 2:
What does rendering video mean, what is fps, and how does it affects the video?
Q3. What is the purpose of Package Explorer? In the figure below, important
files/directories are pointed with numbers 1—7. Briefly explain each of the
numbered items one by one.
Explanation / Answer
(1) USB 3.1 is the successor to USB 3.0. Identifiable by its bright turquois port, USB 3.1 doubles the transfer speed of 3.0 to a whopping 10 Gbps. USB Power Delivery 2.0 makes a big step forward as well with up to 100W of power. And like previous versions of USB, it is fully backwards compatible with its predecessors.
USB 3.1 was an update to that which increased the maximum power that could be used, and doubled the speed of USB 3.0. Despite being released in 2013, there's really nothing out there that does USB 3.1 yet.
USB-C extends USB 3.1 by introducing a single new reversible connector (about the size of a USB Micro-B connector), power profiles that allow up to 100W, and bi-directional power flow (it can be used both to connect a charger, and to power devices).
(2)--> video rendering : video rendering is the final output process of taking a group of video and audio clips, and perhaps animation and special effects applied, leaving you with one neat package to watch and listen
-->Frames per second (FPS) is a unit that measures display device performance. It consists of the number of complete scans of the display screen that occur each second. This is the number of times the image on the screen is refreshed each second, or the rate at which an imaging device produces unique sequential images called frames.
Each frame is a still image; displaying frames in quick succession creates the illusion of motion. The more frames per second (fps), the smoother the motion appears
Television in the U.S., for example, is based on the NTSC format, which displays 30 interlaced frames per second (60 fields per second). In general, the minimum fps needed to avoid jerky motion is about 30. Some computer video formats, such as AVI, provide only 15 frames per second.
(3)--> Src :User specified java source code files will be available here.
-->gen : The gen directory in an Android project contains auto generated files. You can see R.java inside this folder which is a generated class which contains references to certain resources of the project. R.java is automatically created by the Eclipse IDE and any manual changes are not necessary.
-->bin :Bin folder is the area used by the compiler to prepare the files to be finally packaged to the application’s APK file. This includes
-->AndroidManifest.xml :
All the android applications will have an AndroidManifest.xml file in the root directory. This file will contain essential information about the application to the Android system, information the system must have before it can run any of the application's code. This control file describes the nature of the application and each of its components
-->/res/values :
Used to define strings, colors, dimensions, styles and static arrays of strings or integers. By convention each type is stored in a separate file, e.g. strings are defined in the res/values/strings.xml file.
-->/res/drawable :
Drawable folders are resource directories in an application that provides different l bitmap drawables for medium, high, and extra high density screens.
-->/res/drawable-hdpi - bitmap for high density
