MAN stands for the Metropolitan Area Network. It is represented as the computer network that joins the metropolitan areas. MAN works either through wires or modem. Telephone company network is an instance of MAN as they support highspeed DSL line to the consumers.The features of MAN is that it is the interconnection between several connection in a metropolitan area. Point-to-point connections are used in MAN. The network size of MAN ranges from 5-50 Kms.MANs are completely efficient and can support fast communication via high-speed carriers, including fiber optic cables. The rise of wireless and successive networking technologies, though, means a ... Read More

WAN stands for Wide Area Network. A Wide Area Network is a network that extends over a large geographical area including states or countries. A Wide Area Network supports a large geographical area. Suppose if the branch of the office is in a multiple city then it can link with them through WAN. The internet supports a leased line through which it can connect with multiple branch.WANs are set of interconnected local area networks (LANs), which are defined to a physical areas. WANs are created by telecommunications service providers, who then lease these capabilities to multinational or otherwise high enterprises ... Read More

LAN stands for Local Area Network. A Local Area Network (LAN) is a set of computers and associated devices that send a common communications line or wireless connection and share the resources of an individual processor or server inside a small geographic area generally within an office building.Generally, the server has applications and data storage that are shared in common by several computer users. A local area network can serve as few as two or three users (for instance, in a home network) or as some thousands of users.LANs have become commonplace in several organizations for supporting telecommunications network capabilities ...

There are three types of Networks in Information Security which are as follows −Local Area Network (LAN) − Local area network is a computer network that works in a small area, i.e., it connects computers in a small geographical location like inside an office, company, school, or any other organization. Therefore, it exists within a specific location, such as home network, office network, school network, etc.A local area network can be a wired or wireless network or a set of both. The devices in a LAN are usually linked using an Ethernet cable, which provides an interface to connect multiple ... Read More

There are several benefits of networking which are as follows −Connectivity and Communication − Networks connect devices and the customer of those computers. Individuals inside a building or work group can be linked into Local Area Networks (LANs).LANs in distant areas can be interconnected into higher Wide Area Networks (WANs). Once connected, it is applicable for network users to connect with each other using technologies including electronic mail. This creates the transmission of business (or non-business) data easier, more effectiveness and less expensive than it would be without the network.Data Sharing − The main benefit of networking is to allow ...

A network is simply a set of computers or other hardware devices that are linked together, such as physically or logically, using special hardware and software, to enable them to exchange data and cooperate. In networking, it can defines the processes included in designing, executing, upgrading, handling and working with web and network technologies.Network security includes the provisions made in an underlying computer network infrastructure, policies adopted by the network management to secure the network and the network-accessible resources from unauthorized access and consistent and continuous monitoring and analysis of its effectiveness (lack) combined together.Network security is a group of ...

Key success factors are the important component needed for a company to compete in its target industry. For some effectual biometrics system, there are a some essential factors associated with it including accuracy, speed and throughput rate, acknowledgment by users, exclusiveness of biometrics organ and action, reliability, data storage requirement, enrolment time, intrusiveness of data collection, etc. An effective implementation of biometrics system would base on these factors as follows −Accuracy − It is the essential trait of a biometric identification verification system. If the system cannot accurately separate an authentic person from an imposter, it should not be treated ... Read More

A biometric technique that uses characteristics of a person’s signature (such as pressure, pen lifts, speed and direction of pen strokes) to authenticate identity. Signature is less efficient than some multiple biometrics (e.g., fingerprints, iris) but is famous in file authentication applications that have been used written signatures. Some growth can be fueled by the maintenance of pen-based devices (e.g., the PalmPilot) that can match as a signature input tablet.Signature verification technology is the determination of an individual’s written signature, such as the speed, acceleration cost, stroke length and pressure applied during the signature. There are diverse approach to capture ... Read More

Voice biometrics is the science of using a person's voice as a uniquely identifying biological natures to authenticate them. Voice biometrics also enhance the user experience by eliminating frustration associated cumbersome login processes and lost and stolen credentials.Voice biometrics, creates the person’s voice to test or identify the person. It confirms and recognizes the speaker. A microphone on a standard PC with software is required to test the unique traits of the person. It is generally used in telephonebased applications.Voice verification is easy to use and does not require a big deal of user education. It can enroll the user ... Read More

There are several techniques of biometric which are as follows −Face Recognition − The biometric system can recognize a person by the face. This technology services by analyzing particular traits in the face including the distance among the eyes, width of the nose, position of cheekbones, jaw line, chin, unique shape, pattern etc. These systems involves dimensions of the eyes, nose, mouth, and other facial characteristics for identification.Face recognition captures traits of a face either from video or still image and transforms unique traits of a face into a group of numbers. These data assembled from the face are combined ... Read More
