FSMO Roles
Flexible single master operation (FMSO) is an Active Directory feature. For networks to function properly in an active directory environment, certain roles must be assigned to the Domain Controllers (DC). Such roles are called FMSO roles and the DCs responsible for performing these roles are called FSMO role holders. FMSO roles include three domain specific and two forest specific roles.

Network Topologies
In I.T world we usually have a computer network for business or personal purposes. The term Topology refers to the layout of computer network or connected devices of an organization. I.T experts consider two types of Topology, one is Physical Topology and the other is Logical Topology. Physical topology consists of computer, hardware devices and cabling structure inside a network. However, logical topology provides an idea that how the data are transmitted from one device to another while using physical topology.

Putty Tools
Putty is a terminal emulator and it functions as a client for SSH, rlogin, Telnet, and raw TCP computing protocols. First, we have to understand the term emulator. Emulator is nothing but a software that imitates other hardware or software. Hence, in simple terms, terminal emulators help you to access a mainframe computer from your personal computer and you can work on the main computer from your PC itself. Putty is an open source terminal emulator, so it is available for free.
