Realtek RTL8139 is a fast Ethernet controller that is known for its speed and effective control. It is made in high integration and has a management function that enhances it which is the advance configuration power interface (ACPI).
Its main purpose is the provision of power management for the PCI, mini PCI and the cardbus while working with the new and more developed Operating Systems.
It has many features that include the support of 10 and 100 Megabytes per second. It also supports the PCI clock and it allows for the transfer of data from the PCI master. It offers enough memory space for mapped data transfer since it carries memory space for the PCI. It supports the change of links for instance from Microsoft wakeup frame to AMD magic function that is meant for WOL functioning.
The card further provides support for flow control full duplex and it provides an interface for the storage of resource configuration of 93C46/93C56 EEPROMs as well as the intelligent discovery parameters. It also allows for half duplex capability. It enhances the mode of saving power by the computer when it is not using the wakeup or local area network function. It supports the 3.3V CMOS operations and enhances 3 LEDs for the indication of traffic, speed, links and collisions. It enhances the computer’s pin of PCI clock run as well as a flash memory of up to 128 kb and interfaces for the boot-ROM.
Realtek RTL8139 is used in many applications like in the network interface cards and it is also used in inbuilt network interfaces. It can be used in both Mac and Windows. In networking, it can be shared among many computers in the same network. It is embedded in the motherboard of most notebooks and Mac Operating Systems making it compatible with most computer models. This is an advantage since it is easier to network with different models of computers without conflicts in the network.
The half and full duplex capability enables the card to send and to receive data at the same time without a conflict in the operations. It creates an independent highway for each of these processes and used by those who have much computer traffic. This is because they can offload and load more data on the computer using the Realtek RTL8139 and the computer operations are not affected. Its low power consumption makes it ideal since it minimizes the computer’s power consumption and enhances computer cooling.
