An asynchronous signal is one that is transmitted at a different clock rate than another signal. (plesiochronous signals are almost but not quite in synchronisation - and a method is used to adjust them - and synchronous signals are those that run at the same clock rate.

What this usually means (as in ADSL) is that traffic runs faster in one direction than the other.

Synchronous means happens at the same time.  A in front of a word, can negate the word.  Therefore, Asynchronous means doesn't happen at the same time.

In the context you're referring to, synchronous devices can both communicate at the same time.  Asynchronous devices cannot.

Many home appliance routers speak only Ethernet.  That's fine if your Internet connection uses something that provides conversion to Ethernet, as most cable modems and DSL interfaces do.

A router with a serial port can talk to a range of other sorts of devices.  Some serial connections, such as ISDN and T1 lines, tie everything to a "clock signal" that keeps everything in lockstep.  These tend to be fast, efficient, and expensive.

Cheaper serial interfaces don't use a clock signal.  They lose some efficiency because every byte needs to be bracketed by start (to "wake up" the remote end) and stop bits.  PC serial ports work this way, and so do the serial ports on typical external dial-up modems.  This is called an asynchronous serial connection/port.

If you had a router with an asynchronous serial port on it, you could attach an external dial-up modem to that port and use the dial-up connection as the Internet gateway for a whole network of machines attached to another router port (usually Ethernet).  People who don't have DSL or cable modem or ISDN at their homes, but do have multiple machines, actually find this useful.

These kind of sound like homework questions to me which I thought was against EE policy.
