A computing platform generally possesses a hardware architecture and a software framework that permits application software to operate, for example, the operating system and programming languages.
System software programs operate on their own while application software is totally dependent on it. System software programs run in the background when the system is switched on, while application software interacts with its end users.
Transistors are smaller than electric tubes and have higher operating speed. They have no filament and require no heating. Manufacturing cost was also lower. Thus the size of the computer got reduced considerably.
This is the type of software that enables the computer to manage its resource. It is further dividedinto; Firmware - system software fixed into hardware components e. BIOS.

Here we will learn how to Open and Close an application. An application, sometimes called aprogram, performs a certain task. There are literally hundreds of applications and it would beimpossible for us to know them all. The good news is that applications Open (start) and Close(end) in the same manner.
An application is defined as a computer program designed to help people perform a certain typeof work (or recreation!). Examples of applications include word processing programs,spreadsheets, media players, and even games.
Open an Application via the DesktopLet8s review a few concepts we covered on a previous lessons. The Desktop is the image you seewhen your computer powers on. Located on your Desktop are Icons and these Icons are graphicimages that when clicked will Open or 5start6 a program. Placed on your Desktop is an Icon toa commonly played card game called Solitaire. We will use this application to practice Openingand Closing an application.
Slowly move your mouse over to the list of games and down (not diagonally - straight over andthen straight down!) to Solitaire. Once your mouse is on Solitaire click your mouse to open theapplication. Solitaire should open as you saw earlier. Once again, you can close the applicationwith the X in the upper right hand corner.

Computer education is rapidly increasing the graph of number of computer students. There are a number of methods in which educational institutions can use a computer to educate the students. It is used to prepare a database about performance of a student and analysis is carried out on this basis.
Operating systems are there from the very first computer generation and they keep evolving withtime. In this chapter, we will discuss some of the important types of operating systems which aremost commonly used.
Batch operating systemThe users of a batch operating system do not interact with the computer directly. Each userprepares his job on an off-line device like punch cards and submits it to the computer operator.To speed up processing, jobs with similar needs are batched together and run as a group. Theprogrammers leave their programs with the operator and the operator then sorts the programswith similar requirements into batches.
Time-sharing operating systemsTime-sharing is a technique which enables many people, located at various terminals, to use aparticular computer system at the same time. Time-sharing or multitasking is a logical extensionof multiprogramming. Processor's time which is shared among multiple users simultaneously istermed as time-sharing.
Distributed operating SystemDistributed systems use multiple central processors to serve multiple real-time applications andmultiple users. Data processing jobs are distributed among the processors accordingly.
The processors communicate with one another through various communication lines (such ashigh-speed buses or telephone lines). These are referred as loosely coupled systems ordistributed systems. Processors in a distributed system may vary in size and function. Theseprocessors are referred as sites, nodes, computers, and so on.
With resource sharing facility, a user at one site may be able to use the resources available at another. Speedup the exchange of data with one another via electronic mail. If one site fails in a distributed system, the remaining sites can potentially continue operating. Better service to the customers. Reduction of the load on the host computer. Reduction of delays in data processing.
Network operating SystemA Network Operating System runs on a server and provides the server the capability to managedata, users, groups, security, applications, and other networking functions. The primary purposeof the network operating system is to allow shared file and printer access among multiplecomputers in a network, typically a local area network (LAN), a private network or to othernetworks.
DOS - Disk Operating System - one of the first operating systems for the personal computer. When you turned the computer on all you saw was the command prompt which looked like *c:* >. You had to type all commands at the command prompt which might look like c:>wp\wp. This is called a command-line interface. It was not very "user friendly" Windows - The Windows operating system, a product of Microsoft, is a GUI (graphical user interface) operating system. This type of "user friendly" operating system is said to have WIMP features: o W indows o I cons o M enus o P ointing device (mouse) MacOS - Macintosh, a product of Apple, has its own operating system with a GUI and WIMP features. Unix - Linux (the PC version of Unix) - Unix and Linux were originally created with a command- line interface, but recently have added GUI enhancements. 006ab0faaa
