Routing

Routing is the process of selecting best paths in a network. In the past, the term routing was also used to mean forwarding network traffic among networks. However this latter function is much better described as simply forwarding. Routing is performed for many kinds of networks, including the telephone network (circuit switching), electronic data networks (such as the Internet), andtransportation networks. This article is concerned primarily with routing in electronic data networks using packet switching technology.

Know about Access Control Systems and Their Types with Features

Many access control systems use network for communication purpose and information is communicated through these networks.Access control systems are the electronic systems that are designed to control through a network and they should have an access to a network. Access Control System recognizes authenticates and authorizes entry of a person to enter into the premise thereby giving complete protection ensuring security with the system.

Example of an access control system :
A door may be unlocked with a swipe card, an RFID system or by the technology of bio metric system.

What is access control system?

Access control system provides security by giving flexible control over who is allowed to enter your premises. Access control system is one of the most common used system in electronic door control using a card or a magnetic stripe which can be accessed by swiping through a reader on the door. These access control systems are used for security purposes.

White Paper On Wireless Communication through Zigbee Technology Pdf

Wireless communication technology usage is rapidly increasing nowadays in applications such as wireless sensor networks, industrial automation systems, home automation systems, remote control systems, medical care equipments, automation systems for agricultural use, and other applications. Among various communication technologies, Zigbee is an emerging and very promising international standards-based wireless-communication technology.

ZigBee technology is a wireless sensor network system which ensures remote monitoring and controlling of load parameters. Some of the characteristics like low cost, low power, low data rate, easy installation, low maintenance, multiple topologies, etc., makes this communication more suitable for a wide variety of applications compared to other short-range communication technologies.

CTI (computer-telephony integration) definition

CTI (computer-telephony integration), or sometimes simply "computer telephony," is the use of computers to manage telephone calls.

CTI (computer-telephony integration), or sometimes simply "computer telephony," is the use of computers to manage telephone calls. The term is used in describing the computerised services of call centers, such as those that direct your phone call to the right department at a business you're calling. It's also sometimes used to describe the ability to use your personal computer to initiate and manage phone calls (in which case you can think of your computer as your personal call center).

Introduction to Modulation and Different Types of Modulations

We are living in an era of communication wherein we can easily transfer any information (video, audio and other data) in the form of electrical signals to any other device or destined area. Although it is common in our perceptual experience that sending or receiving signals or data is simple, but it involves quite complex procedures, possibilities and scenarios within the communication systems.

Modulation plays a key role in communication system to encode information digitally in analog world. It is very important to modulate the signals before sending them to the receiver section for larger distance transfer, accurate data transfer and low-noise data reception.
