Objective :  To study various cards used in a system viz. display card, LAN card etc.

Theory:  1.LAN Card

The LAN Card provides a direct interface to your Ethernet 10Base-TLAN or other types of LANS through commercially available bridges. It makes the IDS a network addressable device and supports TCP/IP connections to PCs and other network devices. The LAN Card also leverages the open, standards-based utilities of the LAN, including Simplified Network Management Protocol (SNMP), Trivial File Transfer Protocol (TFTP), Telnet and Ping, to manage the functionality of the device.

Executone’s LAN Card is a sophisticated Computer Telephony Integration (CTI) enabling device that enhances functionality and integration with customer’s LANs. Users who have access to their organization’s network can manage Executone’s Integrated Digital System (IDS™) through their desktop PCs using their existing LAN.

By eliminating the need for a dedicated connection between the phone system and administrative terminals, more users can gain access to critical information simply by connecting to their LAN---your administrators and Automatic Call Distribution (ACD) group managers no longer need standalone terminals on their desks. The LAN Card speeds up processes, such as back-up and restore, from minutes to seconds. Executone’s LAN Card also increases overall system security by leveraging existing LAN security tools

2. Display Card

A video card, video adapter, graphics-accelerator card, display adapter, or graphics card is an expansion card whose function is to generate and output images to a display. Many video cards offer added functions, such as accelerated rendering of 3D scenes, video capture, TV-tuner adapter, MPEG-2 and MPEG-4 decoding, Fire Wire, light pen, TV output, or the ability to connect multiple monitors, while other modern high performance cards are used for more graphically demanding purposes such as PC games.

Video hardware can be integrated on the motherboard, as it often happened with early computers; in this configuration it was sometimes referred to as a video controller or graphics controller. 

DisplayPort

An advanced license- and royalty-free digital audio/video interconnect released in 2007. DisplayPort intends to replace VGA and DVI for connecting a display to a computer.
