A network protocol used by a network client to obtain its IP address automatically. This is usually done during the bootstrap process of computers or operating systems running on them. The BOOTP servers assign the IP address from a pool of addresses to each client. BOOTP enables 'diskless workstation' computers as well as other networked devices (printers...) to obtain an IP address prior to loading any advanced operating system.
The bounce rate is the percentage of visitors who leave a web site after viewing a single page.
This is widely regarded as a bad thing because it may mean that visitors did not find what they were looking for and "bounced" away to another site. They left almost immediately.
However, this is a broken metric in many cases. For example if you were looking for opening times of a retailer in your city and you found that info right on the homepage of the retailer, you will technically leave the site after a single page view. However it does not mean you did not find what you were looking for.
Furthermore you may have visited some competing sites in a row, "bouncing" from on e to the next, still finding the exact information (closing times) on each of them in a single page view each.
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 Hard Disk Drive (HDD) a.k.a. hard drive or hard disk, is a non-volatile storage device. It stores digitally-encoded data on rapidly rotating platters with magnetic surfaces.
An image type that simulates grayscale by varying the density of dots in a given area.
Highly colored areas consist of a large density of dots, while lighter areas consist of a lower density of dots.
Shades of gray that represent light and dark portions of an image.
When color images are converted to grayscale; colors are represented by various shades of gray depending on their brightness.
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.
Term used for a toner usage measurement on laser printing. For example, 5% coverage means that an A4 sided paper has about 5% image or text on it. So, if the paper or original has complicated images or lots of text on it, the coverage will be higher and at the same time, a
toner usage will be as much as the coverage.
Measurement of resolution that is used for scanning and printing. Generally, higher DPI results in a higher resolution, more visible detail in the image, and a larger file size.
File format used to exchange data between disparate applications. The file format, originally
introduced by Microsoft Excel, has become a de facto standard throughout the industry, even among non-Microsoft platforms.
