Appendix 10VarioLink 2221/2821/3621 10-710.3 GlossaryTerm Definition10Base-T/100Base-TX/1000Base-TA standard for Ethernet, which is connected through a cable consist-ing of twisted copper wire pairs. The transmission speed of 10Base-T is 10 Mbps, of 100Base-TX is 100 Mbps, and of 1000Base-T is1000 Mbps.Active Directory A service that manages all information such as hardware resourcesfor servers, clients, and printers on a network supported by Micro-soft and the attributes and access permissions of the usersAPOP Abbreviation for Authenticated Post Office Protocol. An authentica-tion method with encrypted passwords, which results in increasedsafety, as compared to the usual unencrypted passwords used byPOP to retrieve e-mail messagesAuto IP A function for automatically acquiring the IP address. If acquisitionof the IP address failed with DHCP, an IP address is acquired fromthe address space of 169.254.0.0.bit Abbreviation for Binary Digit. The smallest unit of information (dataquantity) on a computer or printer. Displays data using 0 or 1.BMP Abbreviation for Bitmap. A file format for saving image data that usesthe .bmp extension. Commonly used on Windows platforms. Youcan specify the color depth from monochrome (2 values) to full color(16,777,216 colors). Images are not usually compressed whensaved.Byte Unit of information (data quantity) on a computer or printer. Config-ured as 1 byte equal to 8 bits.Client A computer that uses the services provided by a server through anetworkContrast The difference in intensity between the light and dark parts of the im-age (light/dark variation). An image with little light/dark variation issaid to have a low contrast, and an image with large light/dark vari-ation is said to have a high contrast.Default The initial settings. The settings first selected when the machine isturned on, or the settings first specified when the function is select-ed.Default Gateway A device, such as a computer or router, used as a "gateway" to ac-cess computers not on the same LANDensity An indication of the amount of darkness in the imageDHCP Abbreviation for Dynamic Host Configuration Protocol. A protocol inwhich a client computer on a TCP/IP network automatically specifiesthe network settings from the server. With collective management ofthe IP address for DHCP clients on the DHCP server, you can avoidduplication of an address and you can build a network easily.DNS Abbreviation for Domain Name System. A system that acquires thesupported IP addresses from host names in a network environment.DNS allows the user to access other computers over a network byspecifying host names, instead of difficult to memorize and under-stand IP addresses.
