What is Operating System's ?
A computer's operating system is one of the most important "parts" of the computer. Almost every type of computer, including cellular telephones, needs an operating system in order to operate properly. When one turns on a computer, the operating system tells the computer what to do by controlling the system resources such as the processor, memory, disk space, etc. The operating system allows the user to work on the computer without having to know all the details about how the hardware works.
When choosing an operating system for a business, the primary considerations should be the hardware platform used, the number of users and attendant system security requirements, the ease of administration, the adaptability toward different uses, and the different applications that will be employed.
Operating System have the Following Characteristics:-
1) Operating System is a Collection of Programs those are Responsible for the Execution of other Programs.
2) Operating System is that which Responsible is for Controlling all the Input and Output Devices those are connected to the System.
3) Operating System is that which Responsible is for Running all the Application Software’s.
4) Operating System is that which Provides Scheduling to the Various Processes Means Allocates the Memory to various Process those Wants to Execute.
5) Operating System is that which provides the Communication between the user and the System.
6) Operating System is Stored into the BIOS Means in the Basic Input and Output System means when a user Starts his System then this will Read all the instructions those are Necessary for Executing the System Means for Running the Operating System, Operating System Must be Loaded into the Computer For this, this will use the Floppy or Hard Disks Which Stores the Operating System.
TYPES OF OPERATING SYSTEMS
Most simple, single-function computers (such as in microwave ovens with digital keypads) do not require an operating system. In fact, trying to implement an operating system in these computers would be overkill. On the other hand, all personal desktop and laptop computers and servers do require an operating system. While there are hundreds of operating systems available, the most popular by far are the Microsoft Windows family of operating systems, the Macintosh operating system, and the Unix family of operating systems.
There are four general types of operating systems. Their use depends on the type of computer and the type of applications that will be run on those computers.
Real-time operating systems (RTOS) are used to control machinery, scientific instruments, and industrial systems. In general, the user does not have much control over the functions performed by the RTOS.
Single-user, single task operating systems allow one user to do one thing at a time. And example of a single-user, single task operating system is the operating system used by personal digital assistants (PDAs), also known as handheld computers.
Single-user, multi-tasking operating systems allow a single user to simultaneously run multiple applications on their computer. This is the type of operating system found on most personal desktop and laptop computers. The Windows (Microsoft) and Macintosh (Apple) platforms are the most popular single-user, multi-tasking operating systems.
Multi-user operating systems allow multiple users to simultaneously use the resources on a single computer. Unix is an example of a multi-user operating system.
What is the basic difference between different operating systems?
DOS (Disk Operating System)
gained a reputation by supporting operating systems developed by IBM and Windows. DOS was prominent in the industry up until support was terminated for Windows ME. Though it's not as sophisticated as modern systems, DOS offers many advantages to the user. This system is very stable and rarely endures crashes. It can display content on an arcade monitor without the aid of special hardware and the use of batch files offer a high degree of customization. While the system is still used, DOS has become more difficult to manage as support is limited.
Linux
The Linux operating system is developed on a kernel based on Unix. It is known as one of the most secure platforms, yet Linux is often viewed as more complex. Linux is the result of an open-source project, allowing users and developers to access the source code for free. Because it requires less hardware, Linux is capable of providing exceptional performance even on a smaller hard disk. Large communities of users exist for this system, constantly contributing to the code and making improvements. The server-based concept of Linux has resulted in fewer home users and a lack of multimedia support for the system.
Mac OS X
Mac OS X is Apple's trademark operating system software for their line of Macintosh computers. The system was based in part on Unix and mimics it's format with the administrative controls. Mac OS X software requires a low level of maintenance with fewer occurrences of computers worms, viruses and spyware. The Apple operating system does have some disadvantages, primarily in regard to software and hardware compatibility.
Windows
The Microsoft Windows operating system is the most popular choice and currently has a stronghold over the market. This platform has made significant advancements from version 1.0 all the way to the new Vista system. The Windows system is highly compatible, feature-rich and has a much larger selection of software applications. Unlike the Linux kernel, Windows is proprietary software and tends to be more expensive than others. Despite widespread usage, Windows has been heavily associated with the term "insecure" as a number of security vulnerabilities have made it the most targeted system. Frequently exploited by hackers and malicious code writers, it is recommended that any Windows operating system with internet access be protected by some form of security software. Although the XP version is still popular among users, support for this system will conclude in 2009 as more emphasis will be placed on developing the Vista series.
What is MS-DOS?
Short for Microsoft Disk operating system, MS-DOS is a non-graphical command line operating system derived from 86-DOS that was created for IBM compatible computers. MS-DOS originally written by Tim Paterson and introduced by Microsoft in August 1981 and was last updated in 1994 when MS-DOS 6.22 was released. MS-DOS allows the user to navigate, open, and otherwise manipulate files on their computer from a command line instead of a GUI like Windows.
What is Android?
Android is the name of the mobile operating system made by American company; Google. It most commonly comes installed on a variety of smart phones and tablets from a host of manufacturers offering users access to Google’s own services like Search, YouTube, Maps, Gmail and more.
This means you can easily look for information on the web, watch videos, search for directions and write emails on your phone, just as you would on your computer, but there’s more to Android than these simple examples.
Difference Between Application Software And System Software
Operating System is the System Software that makes the Computer work. We can say that an Operating System (OS) is Software that acts as an interface between you and the hardware. It not only contains drivers used to speak the hardware's language, but also offers you a very specific graphical user interface (GUI) to control the computer.
An OS can also act as an interface (from the hardware) to the other software. A complex OS like Windows or Linux or Mac OS offers the services of an OS, but also has applications built in. Solitaire, Paint, Messenger, etc. are all applications.
Application software is the software that you install onto your Operating System. It consists of the programs that actually let you do things with your computer. These Applications are written to run under the various Operating Systems.
These include things like your word processing programs, spread sheets, email clients, web browser, games, etc. Many programs, such as most of the Microsoft Office suite of programs, are written in both Mac and Windows versions, but you still have to have the right version for your OS.
For example - Tally for Accounting, MS-Word for Word Processing etc.
So, the Operating system of a Computer is the Software that allows the Computer work. It provides the framework under which the Applications run. An operating system is the type of Computer system you have such as Window XP or Window 95, 98, Mac, etc.
The Applications are the Software that actually allows the user to do something with the Computer. Without the applications, all you can do is change settings and navigate among the folders. You can purchase its CD from a software company or download from a software company’s web site.
History of MS-DOS
MS-DOS (Microsoft Disk Operating System) is a single-user, single-tasking computer operating system that uses a command line interface. In spite of its very small size and relative simplicity, it is one of the most successful operating systems that has been developed to date.
Some of the most common commands are as follows (corresponding commands on Unix-like operating systems are shown in parenthesis):
CD - changes the current directory
COPY - copies a file
DEL - deletes a file
DIR - lists directory contents
EDIT - starts an editor to create or edit plain text files
FORMAT - formats a disk to accept DOS files
HELP - displays information about a command
MKDIR - creates a new directory
RD - removes a directory
REN - renames a file
TYPE - displays contents of a file on the screen
Write the definition of WordPad ?
WordPad is a word processor for creating, editing, and printing the documents.
Write the definition of Notepad?
Notepad is a very basic generic text editor included with Microsoft Windows that enables someone to open and read plain text files. if the file contains special formatting or is not a plain text file, Notepad will not be able to be read its contents.
WORDWRAP :
Word Wrap is used for wrapping the writing documents within the documents area. if you work without wraping, your text documents go on up to the end of the workspace horizontally in one line still, the line will never break till enter button should be pressed.
