How a router works and what does it do?

We begin this review by describing what a router: A router is a network element, Internet and LAN traffic, divides the available bandwidth between a number of interconnected computers that filters packets, it acts as a firewall hardware configuration, Network Gateway , NAT server-based controls and wireless access point (in the case of a wireless router). A wireless router is essentially a set of network adapters connected internally by an intelligent switch that directs incoming and outgoingThe traffic between them.

A hardware router functions, comparing IP addresses written rules and directs the traffic packet destination IP addresses (IP addresses are always packed in packets). All Internet connections are open between two points through multiple routers over worked their way to the final destination, and all routers are packet filtering based on rules set (not necessarily the same rules) and then package in the right direction . If aThe package does not meet the criteria to be eliminated, therefore, never reach their destination.

A network router adds a new level of security, better solutions than the security software installed on your system. And 'even faster when the filtering of traffic and requires less resources than a security software for their work to be done. Most routers allow you to be able to update the firmware for new features and encryption protocols, add repair bugs, but this depends on the manufacturer, is it not aRule.

Local Area Network) network packets (Ethernet typically can not pass through a router, which means that you can not transfer files and folders between computers router is on both sides of the same, but there are some solutions, such as tunnel VPN, Remote Desktop Connection software or a router configured as a bridge between two networks.

A wireless router is vulnerable from a security model available as wired, as it can be hacked from afar, withoutphysical access to their constituents, but when a stronger security protocol and / or MAC filtering table used things are under your control. You should always read your router's manual to figure out what the best solutions available for securing your network.
