t. e. The Domain Name System (DNS) is a hierarchical and distributed name service that provides a naming system for computers, services, and other resources on the Internet or other Internet Protocol (IP) networks. It associates various information with domain names (identification strings) assigned to each of the associated entities.
Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior. Devices that typically support SNMP include cable modems, routers, network switches, servers, workstations, printers, and more.
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface. Packet Tracer makes use of a drag and drop user ...
In computer networks, a tunneling protocol is a communication protocol which allows for the movement of data from one network to another. It can, for example, allow private network communications to be sent across a public network (such as the Internet), or for one network protocol to be carried over an incompatible network, through a process called encapsulation.
Extensible Messaging and Presence Protocol (abbreviation XMPP, originally named Jabber[1]) is an open communication protocol designed for instant messaging (IM), presence information, and contact list maintenance. [2] Based on XML (Extensible Markup Language), it enables the near-real-time exchange of structured data between two or more network ...
Code diversity makes it less likely that a performance or security bug in one DNS server could be exploited to inflict a Denial of Service attack upon an organization. It is for this reason that NSD and Knot DNS are frequently used by root and TLD operators. DNS management software can greatly simplify publishing DNS data to varying DNS servers ...
Request for Comments. A Request for Comments (RFC) is a publication in a series from the principal technical development and standards-setting bodies for the Internet, most prominently the Internet Engineering Task Force (IETF). [1][2] An RFC is authored by individuals or groups of engineers and computer scientists in the form of a memorandum ...
Wireless security. Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks. The term may also refer to the protection of the wireless network itself from adversaries seeking to damage the confidentiality, integrity, or availability of the network. The most ...
