DWDM stands for Dense Wavelength Division Multiplexing. DWDM is a technology used to increase the capacity of fiber optics that results in faster transfers of data. What are fiber optics? Fiber optics are very thin and small fibers that are used to transmit data and light throughout a computer and network. How does DWDM affect …
An Ethernet crossover cable can be used to directly connect two network devices through Ethernet. These can either be single computers or they can be networks. Ethernet crossover cables are commonly used for temporarily networking two devices in the absence of a network router, switch, or hub. The principle is the same, but the connection …
A static route is one that a network administrator creates manually. The opposite of a static route is a dynamic route. Dynamic routes are created by routing protocols. Static routes have advantages and disadvantages when compared to dynamic routes. Advantages of Static Routes: Easy to configure No routing protocol overhead Disadvantages of Static Routes: Network …
Coaxial cable, also called coax, is used to transmit radio frequency (RF) signals. It has low emission losses and provides protection from electromagnetic interference, allowing signals with low power to be transmitted over longer distances. Coaxial cable is comprised of an inner core, insulator, shield, and outer cover. It is called coaxial because these sections …
An Ethernet fiber media converter is a device that allows a connection to be made between an Ethernet and a fiber optic cable. This type of connection is important in situations where both cable types are used in a single household or office. Because telephone companies often use fiber optic cables to deliver telephone and …
Honey monkeys are a new way of detecting malicious codes from websites that try to exploit certain vulnerabilities of Internet browsers. The honey monkey system works as an automated web/internet patrol system that is designed to detect harmful materials in the Internet, to be able to come up with solutions, and to catch the people …
The primary network communications protocol used on networks today is the IP (Internet Protocol). IP relays or transfers network packets, also known as datagrams, to destinations on local networks or across the public Internet. It defines the structures which encapsulate information as well as the legal addressing methods used to identify the source and destination …
The presentation layer is one of seven layers of the OSI (Open Systems Interconnections) Model and is found between the application layer and the session layer. The presentation layer is commonly used for encryption and decryption as well as the conversion of file formats. The presentation layer is considered the last layer in which data …
Bluetooth dial-up networking (DUN) is a wireless Internet technology that refers to connecting to the Internet with a Bluetooth enabled cell phone as a modem. Bluetooth DUN offers a low band alternative where there are no local hotspots to provide high speed wireless Internet access. Bluetooth is a wireless protocol that allows wireless communication to …
Reverse DNS is the process of using DNS to translate IP addresses to hostnames. It is the opposite of forward DNS, which is used to translate hostnames to IP addresses. Internet names are those used to refer to hosts on the Internet, such as www.tech-faq.com and www.freebsd.org. IP addresses are the numbers that Internet routers …
