Router refers to a specific appliance, gateway is a general term; could be a hardware router, software router, firewall etc.<br />

Basically just terminology.

Sandip is right just to add to that gateways operate on any level of the OSI model depending on what it does. like for example translating charachter encodings from ASCII to EBCDIC or IP to IPX

Good question though - It seems that words like gateway and proxy are slapped on to just about anything these days. I would refer to a mail relay as an SMTP or mail gateway for example.<br />
<br />
They can also be referered to as message or mail routers. And both refer to a pure layer 7 function.<br />
<br />
It really depends on the context - PsiCop has the technical definition right by the looks however I've never met anyone in product marketing who knows the OSI model!<br />

gateway/router

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
