Ethernet is the most popular Local Area Network architecture that was jointly developed by Digital Equipment Corporation, Intel Corporation and Xerox Corporation. It consists of certain specifications and standards as well as hardware devices and components. Ethernet provides services corresponding to physical layer and data link layer of the OSI reference model. Each Ethernet physical …
User Datagram Protocol or UDP is part of the Internet Protocol suite. By using UDP, programs running on different computers on a network can send short messages known as Datagrams to one another. UDP can be used in networks where TCP is traditionally implemented, but unlike TCP, it does not guarantee reliability or correct data …
The SSID (Service Set IDentifier) is a name that identifies a specific 802.11 wireless network. The name is set by the network administrator who configures the router. Some vendors refer to the SSID simply as the “network name.” The SSID is the name of the wireless network and should not be confused with the host …
ARP (Address Resolution Protocol) Cache is a technique used to store “mappings” of OSI Model Network Layer addresses (IP addresses) to corresponding OSI Model Data Link addresses (MAC addresses). Due to a variety of possible circumstances, ARP cache can become damaged requiring the end user or administrator to determine how to clear the ARP cache …

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 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 …
