8. What are the advantages of using application software on the Web.
The term application software should be contrasted with system software or system programs such as operating systems. For example, a power generation plant (system) is of no use until utilized to an electric light bulb (application) to provide light to the user. Similarly an operating system is of no use until harnessed to an application program that benefits the user. An operating system runs application programs, which a software user utilizes for achieving some task.
Types of Application Software:
There are various types of application software, these include:
Business application software: Business application or enterprise software deals with the needs of data flow. Various organization processes are also carried out by enterprise software. A business enterprise outsourcing services to an application development firm expects the best solutions to deal with the financial processes of the organization.
Documentation tools and Resource management tools: These application programs come under the category of information worker software. These programs manage individual projects within a department. When outsourcing services to .net application development firm, enterprises expect outstanding documentation and resource management tools for managing information in individual projects with ease.
Simulation software: best examples of simulation software are scientific simulator and flight simulator. These programs are mainly used in both research and entertainment.
A professional .net application development company boasts a highly skilled and experienced team of .net application developers using the Microsoft .Net framework. It also provides helpful ASP.net consulting to web application developers for creating dynamic websites and web applications easily. This helps in the development of cost efficient and innovative business solutions for enterprises.

9. History of the Internet.
The history of the Internet starts in the 1950s and 1960s with the development of computers. This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks.
In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced. Access to the ARPANET was expanded in 1981 when the National Science Foundation (NSF) developed the Computer Science Network (CSNET) and again in 1986 when NSFNET provided access to supercomputer sites in the United States from research and education organizations. The ARPANET was decommissioned in 1990. Commercial internet service providers (ISPs) began to emerge in the late 1980s and 1990s and the Internet was commercialized in 1995 when NSFNET was decommissioned, removing the last restrictions on the use of the Internet to carry commercial traffic.
Since the mid-1990s the Internet has had a drastic impact on culture and commerce, including the rise of near instant communication by electronic mail, instant messaging, Voice over Internet Protocol (VoIP) "phone calls", two-way interactive video calls, and the World Wide Web with its discussion forums, blogs, social networking, and online shopping sites. The research and education community continues to use advanced networks such as NSF's very high speed Backbone Network Service (vBNS) and Internet2. Increasing amounts of data are transmitted at higher and higher speeds over fiber optic networks operating at 1-Gbps, 10-Gbps, or more. The Internet continues to grow, driven by ever greater amounts of online information and knowledge, commerce, entertainment and social networking.

10. What are diferent storage devices.
Primary storage (or main memory or internal memory), often referred to simply as memory, is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required. Any data actively operated on is also stored there in uniform manner.
Secondary storage(also known as external memory or auxiliary storage), differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/outputintermediate area channels to access secondary storage and transfers the desired data using in primary storage. Secondary storage does not lose the data when the device is powered down—it is non-volatile. Per unit, it is typically also two orders of magnitude less expensive than primary storage. Consequently, modern computer systems typically have two orders of magnitude more secondary storage than primary storage and data is kept for a longer time there.
Tertiary storage or tertiary memory, provides a third level of storage. Typically it involves a robotic mechanism which will mount (insert) and dismount removable mass storage media into a storage device according to the system's demands; this data is often copied to secondary storage before use. It is primarily used for archiving rarely accessed information since it is much slower than secondary storage (e.g. 5–60 seconds vs. 1–10 milliseconds). This is primarily useful for extraordinarily large data stores, accessed without human operators. Typical examples include tape libraries and optical jukeboxes.
