ARM is a 32-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by ARM Holdings. It was known as the Advanced RISC Machine, and before that as the Acorn RISC Machine.The relative simplicity of ARM processors made them suitable for low power applications. This has made them dominant in the mobile and embedded electronics market as relatively low cost and small microprocessors and microcontrollers.

What Are Diodes Made Out Of?
Silicon (Si) and Germanium (Ge) are the two most common single elements that are used to make Diodes. A compound that is commonly used is Gallium Arsenide (GaAs), especially in the case of LEDs because of it’s large bandgap.
Silicon and Germanium are both group 4 elements, meaning they have 4 valence electrons. Their structure allows them to grow in a shape called the diamond lattice.
Gallium is a group 3 element while Arsenide is a group 5 element. When put together as a compou ....etc

The client server model
Most interprocess communication uses the client server model. These terms refer to the two processes which will be communicating with each other. One of the two processes, the client, connects to the other process, the server, typically to make a request for information. A good analogy is a person who makes a phone call to another person.
Notice that the client needs to know of the existence of and the address of the server, but the server does not need to know the address of (or even the ex ....etc

Description : Steganography is the art and science of writing hidden messages in such a way that no one apart from the sender and intended recipient even realizes there is a hidden message. By contrast, cryptography obscures the meaning of a message, but it does not conceal the fact that there is a message. Today, the term steganography includes the concealment of digital information within computer files. For example, the sender might start with an ordinary-looking image file, then adjust the color of every 100th pixel to correspond to a lette ....etc

Application of BPCS stenography to wavelet compressed video
Abstract: This paper presents a stenography method using lossy compressed video which provides a natural way to send a large amount of secret data. The proposed method is based on wavelet compression for video data and bit-plane complexity segmentation (BPCS) stenography. In wavelet-based video compression methods such as 3-D set partitioning in hierarchical trees (SPIHT) algorithm and motion-JPEG2000, wavelet coefficients in discrete wavelet transformed video are quantized into a bit ....etc

Stenography
Introduction
Steganography is the art and science of hiding communication; a steganographic system Thus embeds hidden content in unremarkable cover media so as not to arouse an eaver droppers suspicion In the past, people used hidden tattoos or invisible ink to convey steganographic content oday, computer and network technologies provide easy to-use communication channels for steganography. Essentially, the information-hiding process in a steganographic system starts by ide ....etc
