Mobile device management is the administration of mobile devices, such as smartphones, tablet computers, and laptops. MDM is usually implemented with the use of a third-party product that has management features for particular vendors of mobile devices.

Blue Bullet Tip Number 5


Virtual Private Network. A virtual private network extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.

Blue Bullet Tip Number 6


Multi Factor Authentication. Multi-factor authentication is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more pieces of evidence to an authentication mechanism: knowledge, possession, and inherence.

Blue Bullet Tip Number 7


SSH File Transfer Protocol. SSH File Transfer Protocol is a network protocol that provides file access, file transfer, and file management over any reliable data stream.

Blue Bullet Tip Number 8


File Transfer Protocol. The File Transfer Protocol is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control and data connections between the client and the server.

Blue Bullet Tip Number 9


Secure Shell. Secure Shell Protocol is a cryptographic network protocol for operating network services securely over an unsecured network. Its most notable applications are remote login and command-line execution. SSH applications are based on a client–server architecture, connecting an SSH client instance with an SSH server.

Remote desktop software can use several different protocols, including RDP, Independent Computing Architecture (ICA), and virtual network computing (VNC), but RDP is the most commonly used protocol. 

Blue Bullet Tip Number 11

This mapping is a critical function in the Internet protocol suite.

Blue Bullet Tip Number 21


Command Line Interface or Common Language Infrastructure.

A command-line interpreter or command-line processor uses a command-line interface to receive commands from a user in the form of lines of text. This provides a means of setting parameters for the environment, invoking executables and providing information to them as to what actions they are to perform.

Common Language Infrastructure (CLI) is a Microsoft specification for running high-level language program applications in different computer systems without changing the application code. CLI is based on the Microsoft .NET concept that some high-level language programs require modifications due to system hardware and processing constraints.

Blue Bullet Tip Number 22


Interface Device. An interface device is a hardware component or system of components that allows a human being to interact with a computer, a telephone system, or other electronic information system.

Blue Bullet Tip Number 23


Internet Protocol. The Internet Protocol is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet.
