controlled (Mitchell, 1999). Store-and-Forward switching refers to a switching method that, after inspection, stores data packets for delivery. The data is received from the sender and passes a cyclic redundancy check along with a check to be sure it fits the required size limitations. After inspection and the check for errors the data is stored or held in physical storage until network availability allows the data to be sent to its destination (Cisco Systems, 2008). Cut-through switching is a method
forward fault frames which is his main disadvantage. For instance, a store and forward device will input the frame, perform several check operation like, cyclic checksum, detect the error and perform some operation to control error if the frames or packet are corrupted. However, a cut through device is so fast that it start begins forwarding the frame before the cyclic checksum and in that case faulty frame also been transmitted, if the packet contain too many faulty frames and transmitted around the
OSI Model Introduction Successful communication of any type contains four key characteristics. These characteristics follow: 1. A sender: This is the person who is sending information. 2. A receiver: This is the person the sender is sending the information to. 3. A common language: If the sender and receiver are going to understand each other, they will need a common language and protocol, or specific method of communicating. 4. A common medium: The sender and receiver could
Technology is constantly changing, and as the capabilities change, so do the issues in Forensic information technology (FIT). FIT is defined as the scientific use or application of information technology (IT) that is used to generate and present digital evidence to be used in courts, legal or other formal proceedings (Volonio). While the use of technology helps get things done faster, it also can present many issues if the proper procedures and tools are not used and followed. An existing issue in
Introduction Body area networks (BAN) are a form of wireless personal area network (WPAN) and it has recently been accepted as 4th generation mobile communications systems taking the form of human to human networking incorporating wearable sensors and communication. BAN is normally thought of as wireless sensor networks (WSN) however in this paper we try to elaborate on how BAN works. BAN can take various forms, it incorporates the use of sensors which can be found in, on or around the body and it
Austin J. DeLaCruz INFS 3370 Dr. Anand S. Kunnathur Communications and Security Issues with RFID As you are well aware by now the world has become increasingly technology oriented. Every day we use technology in one way or another. Whether it be simply checking email or being able to turn our entire house on from the simple push of a button on our smart phone. Whether we like it or not, technology is there. One piece of technology that seems to be gaining attention and garnering more research
Data Encryption Shiqi Luo(701794770) The definition and importance of data encryption Data encryption refers to the process of transforming electronic information into a scrambled form that can only be read by someone who knows how to translate the code. In nowadays business world, it’s the easiest and most practical way to secure the information that we stored and processed, and it’s significant for our sensitive information. For example, as electronic commerce is popular now, the vendors and retailers
