Tell me what is...

Wi-Fi Protected Setup (WPS) is a standard for setting up a wireless home network.

If your wireless access point/router supports WPS, you can configure the wireless network connections easily without requiring a computer. For example, all you may have to do is press a button on the devices to register them on the network.

Duty cycle is the page quantity which does not affect printer performance for a month. Generally the printer has the lifespan limitation such as pages per year. The lifespan means the average capacity of print-outs, usually within the warranty period. For example, if the duty cycle is 48,000 pages per month assuming 20 working days, a printer limits to 2,400 pages a day.

A modulator-demodulator is a device used to transmit digital data over an analog channel. It modulates/demodulates a carrier signal in order to encode digital information onto it.

A modem is typically used to transmit computer data over POTS phone lines.

A domain name looks like some-name.com, another-name.org or even yet_another.ca for example.

Those names are registered centrally for each "Top Level Domain" (TLD) such as .com , .org or .de ( "ca" being teh country code for Canada for example ).

Once a domain name is registered it can be used to locate servers on the internet by using the Domain Name System in order to route e-mail or access web sites.

The Bit depth describes the number of bits used to represent the color of a single pixel in a bitmapped image. Higher color depth gives a broader range of distinct colors. As the number of bits increases, the number of possible colors becomes impractically large for a color map.

1-bit color is commonly called as monochrome or black & white.

The subnet mask is used in conjunction with the network address to determine which part of the address is the network address and which part is the host address.

A subnet mask may look like 255.255.255.0 which means the first 3 bytes are part of the network and the last byte is the address of the host on the subnet.

Another way to write the same network mask as above is /24 which means the 24 first bits (8 bits * 3 bytes) are part of the network.

WPA-PSK (WPA Pre-Shared Key) is special mode of WPA for small business or home users.

A shared key, or password, is configured in the wireless access point (WAP) and any wireless laptop or desktop devices. WPA-PSK generates a unique key for each session between a wireless client and the associated WAP for more advanced security.

A small circuit board that holds memory.

The part of a laser printer that melts the toner onto the print media. It consists of a hot roller and a back-up roller. After toner is transferred onto the paper, the fuser unit applies heat and pressure to ensure that the toner stays on the paper permanently.

This is why paper is warm when it comes out of a laser printer.

Network protocol used for automatic configuration of IP computers/devices. A DHCP server provides configuration parameters specific to the DHCP client host requesting, generally, information required by the client host to participate on an IP network. DHCP also provides a mechanism for allocation of IP addresses to client hosts.
