      802.1p

      802.1p is an IEEE standard that describes mechanisms to prioritize traffic and perform dynamic multicast filtering. Because of its support for priority specification, 802.1p is important for providing Quality of Service (QoS) for better reliability and quality. Quality of Service QoS is a mechanism that allows for better handling of data that passes over a

    • WEP (Wired Equivalent Privacy)

      WEP (Wired Equivalent Privacy)

      Wired Equivalent Privacy (WEP) is the encryption algorithm built into the 802.11 (Wi-Fi) standard. WEP encryption uses the RC4 stream cipher with 40 or 104 bit keys and a 24 bit initialization vector. WEP Key Generation Most 802.11 devices allow WEP keys to be entered using an ASCII passphrase or in hexidecimal format. The conversion

      Ethernet at the Data Link Layer

      Ethernet at the Data Link Layer Ethernet provides services corresponding to Layers 1 and 2 of the OSI reference model, and IEEE 802.3 specifies the physical layer (Layer 1) and the channel-access portion of the Data Link (Layer 2). In addition, IEEE 802.3 does not define a logical link control protocol but does not specify

    • Packet Sniffers

      Packet Sniffers

      Packet sniffing is listening (with software) to the raw network device for interesting packets. When the software sees a packet that fits certain criteria, it logs it to a file. The most common criterion for an interesting packet is one that contains words like “login” or “password.” To packet sniff, obtain or code a packet

    • What is NetBEUI?

      What is NetBEUI?

      NetBEUI (NetBIOS Extended User Interface) is an extended version of NetBIOS, the primary software that allows individual computers to communicate within a given local area network. While NetBIOS itself is most often used to transfer pictures, documents, videos, or other files from one computer to another, NetBEUI is responsible for arranging the actual information in

      Access Control

      Access control is the execution of limitations and restrictions on whoever tries to occupy a certain protected property, thereby keeping people as safe as possible. As modern society moves further into the cyber age, these access control systems become almost completely computer controlled. This article will further explain what access control is, how it works,

      How to Login to a SMC Router

      SMC is a popular brand of wireless routers, but unlike most routers, SMC routers don’t have a universal username and passwords to access its configuration menu. The username and password varies depending on the model. If you want to gain access to your SMC router you can check your manual to see its default username,

      Default Passwords for Belkin Routers

      By default, all Belkin routers’ default username and password is admin (username) while “blank” (leave it blank) for the password. You need to properly connect the router to your modem and PC before you can access the router using a web browser (IE, Firefox, Chrome, etc.).  To access the router’s GUI, all you need to

      Distance Vector Routing Protocol

      Routing Protocols Whenever different networks connect with each other to communicate and to share the data and resources, it is called internetworking. For internetworking, routers must be used on each network or at backbone to route the packets. To route a packet, a router needs to know: Destination Addresses Sources it can learn from Possible
