2. Suggest suitable operating systems for the following activities:

• Distributed computer
• Multimedia Development
• Database Management

A distributed operating system is an operating system which is used with the computers connected together for distributed processing, Distributed process means processing distribution among many processors connected in the from of a network, In the conventional network many dump computers are connected to dedicated server and uses the resources which are attached to that server, But in case of distributed network the computers which are attached to the server, they are not dump rather they are intelligent and are capable of performance all kind of processing at their end. These systems can work as workstations when server is on and can work as desktop systems when server is off, they have more fault tolerance. This makes them more reliable as they can work properly even is some hardware malfunction client server architecture is an example of distributed among the clients and server. Clients are the intelligent system.

One famous distributed operating system is Windows NT and another is an advanced version of Windows NT windows 2000 advanced server.

The main programming features of windows NT was its modular design, This Modularity made windows BT an extensible, secure operating system which could run on a wide range of processor including both CISC and RISC processors. All services of Windows NT was broken into different modules such as

• Object manager
• Process manager
• Virtual memory manager
• Local procedure call
• Input/output manager
• Security reference manager

Windows NT is especially suitable for distributed processing and supports clients’ server architecture. Windows NT is similarly convenient as it is convenient is Win95-98. It is enriched with sophisticated GUI tools.

Now for multimedia development, the operating system used in MAC, MAC OS is a versatile, powerful interface. It has been pioneer is multimedia application. It has enriched with many adorable features such as automatic checks the hard disk, driver and install all the recommended software. Another feature is Sherlock, which is file finding utility, It has ability to access Internet search engines.

Windows is an upgraded version of windows. It is suitable for both multimedia development and database management, Due to its important features it is compatible to work with both multimedia as Data base Management.

Multimedia is a computer system that has the capacity to integrate two or more type of media (text, graphics, image, audio and video) for the purpose of generation, storage representation manipulation and access of multimedia information.

Database Management is an approach of organizing data, a set of programs is provided to facilitate the users in organizing, creating, deleting. Updating their data in a database.

Windows is an operating system, which support multimedia development and management of data in database.

Features of this operating system are.

(a) Easier to use

(b) More reliable

(c) Faster

(d) More Entertaining

With the refinement and new cosmetic look of user interface, navigating operating are smooth.

It regularly test the hard disk, systems fills and configure information, In many case it automatically fixes the problem.

The application loading is faster in it.

It support DVD and digital audio.

It is capable of delivering high quality digital videos and audios to PC monitor.
