File extension	.mp3
File category	Audio
Stands for	MPEG Audio Layer-3
Developer	Fraunhofer- Gesellschaft (A German research institute)
Overview	It is a digital Audio which compresses the tracks using the lossy format. Although, it follows the lossy format, yet, there will be no noticeable change in the quality of audio. It only discards the superfluous information that a human ear is inefficient to process or hear. With the help of the this extension, one can upload and download audio files with ease, irrespective of the internet connection speed even a dial-up connection users can access these files. There are a number of MP3 Blogs(music blogs) available on the internet where maker uploads music files and a user can download the same without any trouble. These blogs help people to get an insight into the music world. Hype Machine is an example of an audio blog.
Technical description	MP3 uses lossy data compression, which means when data is encoded it is not the full original version, it’s a substitute to original copy but in a smaller size. This compression can lead to a decrease in file size, ranging from 75% to 95%. This format is based on perceptual coding due to which this extension screens out the noise, and results in an audio file that uses a low bit rate(lowest bit rate in it is 128kbps). It provides audio of fair sound quality. As it is only an audio file, thereby, if there are any images linked to it then they need to be stored in a separate file.

File extension	.webm
File category	Video
Stands for	Web Media file
Developer	Google(Initially developed by On2, Xiph and Matroska)
Overview	WEBM is a multimedia container used for both audio and video formats. It is open-source and royalty-free software due to this, it can be implemented and changed for improvement by any developer. It uses different codecs to compress files. For instance, for video streams compression it uses VP8 or VP9 video codecs and for audio streams, it uses Vorbis or Opus audio codecs. It provides videos of the highest quality and that too with real-time delivery. It provides users with the playback option on any device which is due to the low computational footprint. It is licensed under BSD(A family of acceptable free software licenses). Besides this, it has another project named as Webp for images.
Technical description	Its structure is based on the Matroska container. That is why it can support both multiplexing and de-multiplexing. It uses core technologies like HTML, HTTP and TCP/IP which can be easily implemented and this is the main reason for its success. VP8 and VP9 are highly efficient to provide video of the highest quality. It is cost-effective due to its greater efficiency for bandwidths. It is a substitute for H.264 and MPEG4 which are patented software and have copyright. Videos of this format allow playback but it is possible only in Android version 2.3 that is Gingerbread and above. When ‘Rockchip’ came into the market in 2001 it made possible the implementation of full hardware of 1080p. Also, LiVES video editor version 1.4.9 allows coding and deflating of videos in real-time.
