what is a duplex?

Question

I want to know what duplex is and its use....

Answer 1

Printer option that prints on both sides of a page. Used when you want to print some manuals, and have it setup like a book, or any other conceivable use

Answer 2

Regarding printing, duplex means the ability to print on both sides of the page. A duplexor is a separate device inside of a printer that flips the page. Not all printers come with duplexors.

Answer 3

In what context are you seeing it used? In Networking, it refers to how computers are connected to various networking devices. Usually, there is one cable running from the switch to your computer, and all data goes over this one cable, both in and out. In full duplex, you would have two cables running between the two, one carrying info into your computer and the other carrying info out.

Let's say you are using a 10Mbps switch (not the fastest, but good enough for this example). In half duplex, you have 10Mbps to use for both incoming and outgoing packets. In full duplex, you would have 10Mbps for inbound and 10Mbps for outbound, in effect doubling your throughput. This is an excellent resolution for businesses where some users require more bandwidth to the servers than others.

For home use, however, you will be set up with half duplex. And that should be more than enough for you since you are probably the only one on that segment.

Answer 4

Duplex in a printer usually means it will print front and back on a piece of paper, i.e., it will print page 1 on one side then turn the paper and print page 2 on the reverse side. Many printers have a manual setting for duplex printing. My HP does. I have to manually insert the paper back in the tray to print on the reverse side.

Answer 5

Basically communication is "duplex" if it can "talk" and "listen" at the same time.
