When setting up a home network, the central host computer should be running the newest version of Windows (normally the most powerful in a common household). Steps to Setting Up a Windows Read More

LAN Segmentation Overview Network segmentation is the terminology used to describe the process of dividing single Ethernet segments into multiple segments. Network segmentation has the following main advantages: Network performance of the LAN is improved. Network congestion issues can be resolved. Available bandwidth is maximized. A few technologies which you can use to perform network segmentation are listed here: The network can be physically segmented with bridges and routers. This type of segmentation directly decreases the number of workstations on the same physical segment. You can use a network switching Read More

Virtual Private Networks (VPNs) enable users to connect to a remote private network through the Internet. Virtual private networks therefore span the Internet because the user connects over the Internet to the remote VPN server. With a VPN, data is first encrypted and encapsulated before it is sent to the remote VPN server. When the VPN server obtains the data, it decrypts the packet so that is can be interpreted. VPNs are usually implemented to: Enable remote access users to connect to and access the network. Provide connectivity between two Read More
