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.
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.
The Joint Photographic Experts Group (JPEG) algorythm is a very commonly used method of compression for photographic images. It is also a file format used for storing or transmitting photos.
The JPEG algorythm is lossy which means some details of the original picture are lost when compressing the algorythm. The algorythm has a quality setting allowing to set a balance between smaller file size and better quality.
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.
Frame-based computer networking technology used in local area networks (LANs). Ethernet defines wiring and signaling for the physical layer, and frame formats and protocols for the media access control (MAC)/data link layer of the OSI model. Ethernet is mostly standardized as IEEE 802.3.
It has become the most widespread LAN technology since the 1990s.
