Virtual LANs (VLANs): what they are and how they work
A Virtual LAN, better known as a VLAN, is a LAN logically realized through the standard 802.1Q, which defines specifications that allow multiple virtual local area networks (VLANs) to be defined distinct, using and sharing the same physical infrastructure. […]

How do you solve difference equations?
The forced response of a DLIT system can be done by iteratively solving a difference equation of order n, or by the discrete convolution of the input with the impulse response of the system. […]
