Ethernet is the most widely used local area network (LAN) technology, that defines wiring and signaling standards for the physical layer of TCP/IP. Ethernet was originally standardized as IEEE 802.3 with a data transmission rate of 10 Mb/s. Newer versions of Ethernet were introduced lately to offer higher data rates. Fast Ethernet and Gigabit Ethernet suppor...

You have a private or public network with servers and workstations that are assigned static and dynamic IP addresses (either private or public IPs). You assigned them the static IP addresses due to NAT (Network Address Translation) or for public access, and dynamic IP addresses via the DHCP. Even if you kept a good record of those assigned IPs, there are tim...

WAP stands for Wireless Application Protocol. This is a well-known and commonly used standardized protocol which defines how wireless communication can take place between mobile devices and a wireless network. This could include devices such as radio transceivers, cell phones, world wide web, newsgroup, instant messaging and any device that can be used for I...

A Wi-Fi (also known as WiFi) is a wireless network technology which allows WiFi enabled devices to communicate with each other, and also share the Internet without wired connectivity. Wi-Fi is based on 802.11 IEEE network standard which uses radio frequency signals to transmit data. The distance supported by Wi-Fi network depends on the type of Wi-Fi radio a...

RJ-45 conductor data cable contains 4 pairs of wires each consists of a solid colored wire and a strip of the same color. There are two wiring standards for RJ-45 wiring: T-568A and T-568B. Although there are 4 pairs of wires, 10BaseT/100BaseT Ethernet uses only 2 pairs: Orange and Green. The other two colors (blue and brown) may be used for a second Ether...

IP Spoofing is a technique used to gain unauthorized access to machines, whereby an attacker illicitly impersonates another machine by manipulating IP packets. IP Spoofing involves modifying the packet header with a forged (spoofed) source IP address, a checksum, and the order value. Internet is a packet switched network, which causes the packets leaving one...

The Dynamic Host Configuration Protocol (DHCP) is a network protocol that functions at the application layer of the Internet Protocol (IP) suite. A server that uses DHCP will be able to dynamically assign IP Addresses and other network configuration parameters to devices on the network; thus, allowing communication to a second network. The protocol can be im...
