The Server Message Block (SMB) protocol is designed to support file sharing, serial ports, printers, and other communications interfaces such as mail slots and named pipes established between two or more computers. The protocol can be used on top of the TCP/IP or other network protocols such as NetBEUI on the Internet. SMB primarily allows …
The sending and receiving of data from a source device to the destination device is possible with the help of networking protocols when data encapsulation is used. The data is encapsulated with protocol information at each OSI reference model layer when a host transmits data to another device across a network. Each layer communicates with …
A WEP (Wired Equivalent Privacy) key is a type of security algorithm for wireless devices that protects a computer from hackers and people who are trying to access someone else’s Internet connection. It consists of the numbers 0-9 and the letters A-F and can be 10, 26, or 58 characters long. For devices within the …
A wireless router is a computer networking device that routes data packets across another computer or across a wireless IP network. The wireless router comes with an 802.11 interface card and antenna. The wireless router antenna is generally what determines the signal strength of the wireless router. If your signal strength is weak, then you …
A printed circuit board (PCB) is a thin board "printed" with electrical wires and made from fiber glass or similar material. PCBs are commonly used in computer devices such as motherboards, network interface cards, and RAM chips. They are relatively cheap and quite fast. When the PCB is fabricated with several layers placed over one …
The usable FTP commands will differ from one FTP client to the next, but these are a set of fairly standard FTP commands as implemented in the FreeBSD FTP client. ! [command [args]] Invoke an interactive shell on the local machine. If there are arguments, the first is taken to be a command to execute …
CSMA/CD (Carrier Sense Multiple Access / Collision Detection) is the protocol used in Ethernet networks to ensure that only one network node is transmitting on the network wire at any one time. Carrier Sense means that every Ethernet device listens to the Ethernet wire before it attempts to transmit. If the Ethernet device senses that …
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 …
Power line networking is one of the options in connecting computers to form a home network. This technology powers a "wireless" and "power free" home network. Power line networking does not require the user to install additional cables and power-consuming networking hardware to set up a home network. Instead, power line networking, uses the existing …
Every Ethernet card had a factory assigned MAC address burned into it when it was made. At times, users may want to change this MAC address to one of their choice. One of the main reasons for doing this is to get around access control lists(s) on a specific router or server, either by hiding …
