Intranet

An intranet is a private computer network that uses Internet protocols, network connectivity to securely divide part of an organization's information or operations with its employees. Sometimes the term refers only to the most perceptible service, the internal website. The same concepts and technologies of the Internet such as clients and servers running on the Internet protocol suite are used to make an intranet. HTTP and other Internet protocols are commonly used as well, such as FTP. There is often a challenge to use Internet technologies to provide new interfaces with corporate legacy data and information systems.
Intranets can help users to locate and view information faster and use applications related to their roles and responsibilities. With the help of a web browser interface such as Internet Explorer or Firefox, users can contact data held in any database the organization wants to make available, anytime and - subject to security provisions - from anywhere within the company workstations, increasing employees' capability to perform their jobs faster, more accurately, and with confidence that they have the right information. It also helps to improve the services provided to the users.
With intranets, organizations can make more information accessible to employees on a "pull" source rather than being deluged indiscriminately by emails.
Intranets can serve as influential tools for communication within an organization, vertically and horizontally. From a communications standpoint, intranets are useful to communicate strategic initiatives that have a worldwide reach throughout the organization. The type of information that can easily be conveyed is the reason of the initiative and what the initiative is aiming to achieve, who is driving the initiative, results achieved to date, and who to speak to for more information.

laptop

A laptop computer, or simply laptop, is a small mobile computer, which usually weighs 2-18 pounds (1-6 kilograms), depending on mass, materials, and other factors. Laptops usually run on a single main battery or from an external AC/DC adapter which can blame the battery while also supplying power to the processor itself. Many computers also have a 3 volt cell to run the clock and other processes in the occurrence of a power failure.
As personal computers, laptops are skilled of the same tasks as a desktop computer, although they are classically less powerful for the similar price. They contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and capable power consumption. Laptops usually have liquid crystal displays and most of them use unusual memory modules for their chance access memory (RAM), for instance, SO-DIMM in lieu of the superior DIMMs. In addition to a built-in keyboard, they may utilize a touchpad or a pointing stick for input, though an outside keyboard or mouse can frequently be attached.
