What is the preamble of a data frame?
A preamble is a signal sent to the receiver to indicate that data is on its way. It’s the initial signal, and it’s a part of the Physical Layer Convergence Protocol (PLCP). This essentially prepares the receiver for the impending information, ensuring that no data is lost. A modulation scheme and its identifying information are contained in the header, which is the remaining component of data. The transmission rate and the time it takes to send a whole data frame are also included in the preamble.

Wired router: Like a wireless router, a wired router also uses an Ethernet cable to connect to a modem. It then uses separate cables to connect to one or more devices within the network, create a LAN, and link the devices within that network to the Internet.
How does a router work?
Think of a router as an air traffic controller and data packets as aircraft headed to different airports (or networks). Just as each plane has a unique destination and follows a unique route, each packet needs to be guided to its destination as efficiently as possible. In the same way that an air traffic controller ensures that planes reach their destinations without getting lost or suffering a major disruption along the way, a router helps direct data packets to their destination IP address .
What is the difference between a router and a modem?
Each plays a different but equally important role in connecting networks to each other and to the Internet.

In order to connect a LAN to the Internet, a router first needs to communicate with a modem. There are two primary ways to do this:
What are some of the security challenges associated with routers?
Vulnerability exploits: All hardware-based routers come with automatically installed software known as firmware that helps the router perform its functions. Like any other piece of software, router firmware often contains vulnerabilities that cyber attackers can exploit (one example ), and router vendors periodically issue updates to patch these vulnerabilities. For this reason, router firmware needs to be updated regularly. Unpatched routers can be compromised by attackers, enabling them to monitor traffic or use the router as part of a botnet.
How does a router direct packets?
In order to direct packets effectively, a router uses an internal routing table — a list of paths to various network destinations. The router reads a packet's header to determine where it is going, then consults the routing table to figure out the most efficient path to that destination. It then forwards the packet to the next network in the path.
