 ISA network interface 

card (NIC) is a high-performance card for PCs with an 
Industry Standard Architecture (ISA) bus or Extended 
Industry Standard Architecture (EISA) bus. This NIC is 
referred to as the 3C319 NIC in this guide.

The 3C319 NIC is designed for high network 
performance and trouble-free operation. This section 
describes the performance features of the 3C319 NIC.

3Com’s DynamicAccess

™

 features optimize network 

performance. With the DynamicAccess Class of Service 
feature, you can select the applications—such as 
multimedia sessions-—that require the highest-priority 
access to your network. Based on your selection, the 
network device driver recognizes high-priority applications 
and prioritizes their data transmissions.

The NIC implements dual queues to ensure that 
high-priority traffic gets transmitted before normal-priority 
traffic. When high-priority traffic is available for 
transmission, a high-priority token is requested.

Parallel Tasking

®

 architecture provides the industry’s 

fastest performance by pipelining data between the PC 
and the network. Parallel Tasking technology improves 
network data throughput by overlapping processing 
tasks to speed data transmission and reception.
