The Security Problem in Computing: The meaning of computer Security, Computer. In business, the reliance on networks is even more pervasive than in homes or schools. Like the human networks that we are all part of, computer networks let us share information and resources. You can hardly do anything with data that does not involve a network. BaseTech / Networking Concepts / team / 223089-4 / Blind Folio 0 N etworks are everywhereor so it seems.

This interconnection among the computers makes it possible for the information to share among them. Introduction to Data Communications and Networking, Wayne Tomasi, Pearson Education.Follow us on Facebook and Support us with your LikeQ1: What is computer network and how are they classified?A1: Computer network is a system of interconnected computers and computerized peripherals like printers. Computer Networking and Internet, Fred Halsll, Lingana Gouda Kulkarni, Fifth Edition, Pearson Education1. Computer Communications and Networking Technologies, Gallow, Second Edition Thomson3. Data Communications and Networking, Behrouz A Forouzan, Fourth Edition.TMH.2. Computer Networking In Hindi Notes Bluetooth Enabled DevicesThis network has approximately 10 meters of connectivity range. Resource sharing such as printers and storage devicesA3: Smallest network that is very personal to user is called A Personal Area Network (PAN) which may include Bluetooth enabled devices or infra-red enabled devices. Exchange of information by means of emails and FTP Some of the advantages or application are, These networks are classified based on the following factorsA2: To form a network, Computer systems and peripherals are connected with each other. Later, wait for some amount of time and re transmit the data. All the hosts roll back on the occurrence of collision in Ethernet. Using collision detection technology or carrier sens multi access, ethernet detects collision. Network using shared media has high chances of data collision. ![]()
