What are the advantages and disadvantages of using two network cards?

Many computers today have the ability to support dual network cards. The use of this type of technology has several advantages and disadvantages. The primary advantage of two network cards is the ability to connect to two completely independent networks at the same time. This can increase productivity because one machine can work in two separate environments. The disadvantage is the potential security security that occurs via network sharing on one computer.

A computer with two network cards can connect to multiple computers. Most software developers require access to the development environment and a separate test environment. Having two network connections allows developers to access both networks via one computer. Without this function, the developer is forced to use separate computers for each task. These applications are usually matched on a separate training network. A computer with two network cards has access to training and production networks. This configuration saves organizations money,Because an employee can use one computer for training and production. A computer with two network cards can be used as a device for spreading viruses. If a hacker breaks into a dual card computer, he can send malicious software to several networks.

If the computer is connected to the production network and the test network, production data can be easily endangered. This is because production data is based on a computer connected to the test network. If the user accidentally sends this data via the test network, you can see users who should not have access to it.

A company that requires a secret network environment does not allow two network cards on one computer. This is considered to be a violation of security due to vulnerability of data exposure and cyberspace infiltration. Companies with secret proprietary data should refrain from using dual network cards.

some SPOlečnosti uses dual network cards as a method of overall network performance. With this configuration, one network will be connected to the slower capacity server with the other network connected to the high capacity infrastructure. Computer applications can be configured to start the appropriate network infrastructure.

Using dual network cards can be difficult for most start -up users. These network devices may have problems with configuration when restarting your computer. Because the access of dual network is usually advanced configuration, it is not the default configuration for most operating systems.
