What is a JPEG file and why is it popular?
JPEG is a file format and a method of compressing digital images. It is the most common format for storing and transmitting photographic images on the web and other devices. JPEG uses lossy compression, which means some data is lost when converting from a higher quality image format. JPEG files usually have a .jpg or .jpeg extension and can support a maximum image size of 65,53565,535 pixels.
JPEG file format specifications
The original JPEG specification was published in 1992 by the Joint Photographic Experts Group, which created the standard. The specification cites patents from several companies that provided the basis for its arithmetic coding algorithm. The JPEG specification implements processes from various earlier research papers and patents cited by the CCITT (now ITU-T) and Joint Photographic Experts Group.
JPEG compression steps
The process of creating a JPEG file involves several steps, as follows:
Transformation: Color images are transformed from RGB into a luminance/chrominance image (Eye is sensitive to luminance, not chrominance, so that chrominance part can lose much data and thus can be highly compressed.
Down Sampling: The down sampling is done for colored component and not for luminance component .Down sampling is done either at a ratio 2:1 horizontally and 1:1 vertically (2h 1 V). Thus the image reduces in size since the y component is not touched, there is no noticeable loss of image quality.
Organizing in Groups: The pixels of each color component are organized in groups of 88 pixels called data units if number of rows or column is not a multiple of 8, the bottom row and rightmost columns are duplicated.
Discrete Cosine Transformation: Discrete Cosine Transform ( DCT) is then applied to each data unit to create 88 map of transformed components.DCT involves some loss of information due to the limited precision of computer arithmetic. This means that even without the map there will be some loss of image quality but it is normally small.
Quantization: Each of the 64 transformed components in the data unit is divided by a separate number called its Quantization Coefficient (QC) and then rounded to an integer. This is where information is lost irretrievably, Large QC cause more loss. In general, the most JPEG implements allow use QC tables recommended by the JPEG standard.
Encoding - Encoding: The quantized integers are then encoded using a combination of run-length encoding and Huffman coding. Run-length encoding is a method of reducing the number of bits needed to represent a sequence of identical values. Huffman coding is a method of assigning variable-length codes to symbols based on their frequency of occurrence. The result is a stream of bits that represents the JPEG file.
JPEG file advantages and disadvantages
JPEG files have some advantages and disadvantages, as follows:
Advantages
Disadvantages
They can reduce the file size of images significantly without noticeable loss of quality.
They use lossy compression, which means some data is irreversibly lost during the conversion process.
They are widely supported by various devices, applications, and web browsers.
They do not support transparency, animation, or layers.
They can store metadata such as EXIF, IPTC, or XMP, which can provide useful information about the image.
They can be corrupted by viruses, malware, or hardware failures, resulting in unreadable or distorted images.
What is a torrent and how does it work?
A torrent is a file that contains information about a larger file or a collection of files that can be downloaded from multiple sources using a peer-to-peer (P2P) network. A torrent file usually has a .torrent extension and can be opened by a torrent client software. A torrent client software is a program that connects to other users who have the same torrent file and downloads the desired file or files from them.
Torrent file format specifications
The torrent file format was created by Bram Cohen in 2001 and is based on the BitTorrent protocol. The torrent file format consists of five main parts, as follows:
Announce: This is the URL of the tracker server that coordinates the communication between the peers.
Info: This is the metadata about the file or files to be downloaded, such as name, size, hash, piece length, etc.
Pieces: This is a list of SHA-1 hashes of each piece of the file or files to be downloaded. A piece is a fixed-size chunk of data that can range from 16 KB to 4 MB.
Name: This is the name of the file or directory to be downloaded.
Length: This is the total size of the file or files to be downloaded in bytes.
Torrent downloading process
The process of downloading a file or files using a torrent involves several steps, as follows:
The user downloads a torrent file from a website or another source and opens it with a torrent client software.
The torrent client software contacts the tracker server and requests a list of peers who have the same torrent file.
The torrent client software connects to some of the peers and requests pieces of the file or files to be downloaded from them. The peers also request pieces from the user and other peers. This way, the file or files are distributed among multiple users in a P2P network.
The torrent client software verifies each piece by comparing its hash with the one in the torrent file. If the piece is valid, it is saved to the user's device. If not, it is discarded and requested again from another peer.
The torrent client software continues to download pieces from different peers until it has all the pieces of the file or files to be downloaded. Then, it reassembles them into the original file or files and saves them to the user's device.
Torrent file advantages and disadvantages
Torrent files have some advantages and disadvantages, as follows:
Advantages
Disadvantages
They can enable faster and more efficient downloads of large files or collections of files by using multiple sources instead of one.
They can expose the user's IP address and activity to other users, trackers, ISPs, or authorities, which can pose privacy and security risks.
They can reduce the load on servers and bandwidth costs by distributing the data among users in a P2P network.
They can contain malicious or illegal content that can harm the user's device or violate laws and regulations.
They can allow users to access rare or unavailable content that is not hosted on conventional servers.
They can depend on the availability and reliability of other Hardware failure: Some hardware components such as hard drives, memory cards, or USB drives can malfunction or get damaged, causing errors or loss of data in JPEG files.
Software failure: Some software programs such as photo editors, converters, or viewers can crash or have bugs, causing corruption or alteration of JPEG files.
Improper operation: Some user actions such as shutting down the device abruptly, ejecting the storage device unsafely, or transferring the JPEG files incompletely can cause corruption or damage to JPEG files.
Some of the common symptoms of JPEG corruption are:
Invalid file format error: The JPEG file cannot be opened or recognized by any software program or device.
Grey areas or stripes: The JPEG file shows grey areas or stripes instead of the original image content.
Color distortion: The JPEG file shows incorrect or unnatural colors in some parts of the image.
Pixelation or blurriness: The JPEG file shows low quality or resolution in some parts of the image.
Missing data: The JPEG file shows incomplete or missing image content.
