Cloud Computing.
Definition: Cloud computing is a general term for anything that involves delivering hosted
services over the Internet. These services are broadly
divided into three categories: Infrastructure-as-a-Service (
IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name
cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flowcharts and
diagrams.
Electronic Security
Definition: Protection resulting from all measures
designed to deny to unauthorized persons information of value
which might be derived from the
possession and study of electromagnetic
radiations.
Network operating systems and utility software
Network operating systems: A network operating system (NOS) is a software
program that controls other software and hardware that runs on a network. It also allows
multiple computers, also known as network computers, to communicate with one main

local area network (LAN), a wide area network (WAN), or even two or three computer
networks. The heart of any of these networks, however, is the network operating system.
Utility Software: a kind of system software designed to help analyze,
configure, optimize and maintain the computer. A single piece of utility software is usually called a utility (abbr. util) or tool
