To explain how does a switch work, let me make an introduction to the subject by explaining background of TCP/IP stack layers, frame and the purpose of switch. This will help you to understand the exact operation of switch which is the main agenda here. To allow communication between billions of computer devices, intermediate network […]

In MIMO systems, we have multiple antennas at the transmitter, multiple antennas at the receiver and a radio channel in-between. This is where inputs and outputs comes into play – i.e., we have Multiple Inputs (input signals TO the wireless channel) and Multiple Outputs (output signals FROM the wireless channel).

In this post we are going to focus on the following process: “destination IP field of packet is checked against information stored in router”. The place where routing information is stored is called a routing table.  Routing table contains routing entries, that is list of destinations (often called: list of network prefixes or routes).

As you might be aware, bits are a form of language for machines and packets are series (groups) of these bits that traverse the network. The mechanism via which these packets travel across the network is organized thanks to Internet Protocol (IP is set of common rules, structures and descriptions). In general, we have: END DEVICES (like […]
