A hardware unit that connects the computer to a computer network for communication with other devices is called the Network Interface Card (NIC).In today’s era, numerous computers have the potential to support dual network cards. Multiple computers can be connected through two network cards.
In most cases, Software developers require access to a separate test environment and a development environment.
When a computer has two network connections, it allows the software developers to make use of dual networks using one computer.
In the absence of this technology, software developers need to use two independent computers for each task.
How Network Interface Card works video:
Did you know that majority of the large corporations use discreet training software?
Such applications are maintained on a training network.
Computers having two network cards can access both training and production networks. The entire configuration helps the organizations to cut back the cost and save money.
Why? It’s simple!
Employees can utilize a single computer for both training and production.
Nonetheless, technology has its set of pros and cons.
Pros:
- Two network cards can connect to two completely independent networks simultaneously.
- It enables a single machine to increase productivity and work in two separate environments.
Cons:
- One of the major cons of having dual network cards is security.
- Sharing networks on one computer is vulnerable because it can be used as a virus propagation device.
- Hackers can break into a computer with dual cards and send malicious software onto multiple networks.
In spite of security concerns, few companies have shifted to using dual network cards to manage overall network performance.
In such a configuration, one network is connected to a slower capacity server and the other one is connected to a high-bandwidth server.
