Basic Network Problems Cable Problem: The cable which is used to connect two devices can get faulty, shortened or can be physically damaged. Connectivity Problem: The port or interface on which the device is connected or configured can be physically down or faulty due to which the source host will not be able to communicate with the destination host. Configuration Issue: Due to a wrong configuration, looping the IP, routing problem and other configuration issues, network fault may arise and the services will get affected. Software Issue: Owing to software compatibility issues and version mis ..read more

Introduction of Wireless technology.  Wireless technologies allow one or more devices to communicate with each other without any physical connection such as cables . Wireless technologies use radio frequency transmission for Transmission for transmitting data. Using wireless network data can be transmitted between a wireless computer and a wired computer .User need not disconnect their laptop ;instead they can move around the office and perform their tasks effectively. There are some advantage of using wireless networks over wired network like setting it up and freedom from cable connections ..read more

Hyper-V virtualization represents the foundation of Microsoft’s vision for the cloud operating system. Storage and networking are the walls that help support your virtualization infrastructure. Then, on top of everything, comes management and automation. Together, these different functionalities enable a wide range of cloud solutions that can meet the needs of any business. But the bottom line is that virtualization is at the core of everything in most IT shops nowadays. For example, when IT wants to deploy a new workload (such as a Microsoft SQL Server machine) the common way of doing this (a ..read more
