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.
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 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.
The Digital Living Network Alliance (DLNA) is a standard that allows devices on a home network to share information with each other.
It is typically used to store media files (photos, music, videos...) on a central server and allow devices like connected TVs or music palyers to access these media files directly through the network.
Lightweight Directory Access Protocol (LDAP) is an networking protocol for querying and modifying directory services running over TCP/IP.
Is is often use to verify a login/username against a central directory to allow/reject login and then maybe obtain more detailed information on the user (firstname, lastname, etc.)
