What are the basic requirements for NT?ĩ) What makes UNIX so different from the other operational systems?ġ0 )What are the remarkable features of Windows 95?ġ) Like NT.
Windows 95 requires 486 with 16 megabytes of RAM or Pentium 75-90 with 40 megabytes of free hard disk space. Windows 95 and 98 are DOS compatible, so all programs written for DOS may work under the new operating system. The usage of Windows 95 and its enhanced version Windows 98 is so simple that even little kids learn how to use it very quickly. Windows 95& 98are the most popular user-oriented operating systems with a friendly interface and multitasking capabilities. Most users would not purchase UNIX for their own use. Unlike NT and OS/2, UNIX is not DOS compatible. UNIX allowed each user to simultaneously run the programs they desired.
Traditionally, UNIX was run on a larger mini computers to which users accessed the systems using terminals and not PC's. UNIXis a multi-user operating system that allows multiple users to access the system. Many IBM-based PCs are shipped with OS/2 prein-stalled. Also like NT, OS/2 performs best when you are using a powerful system. Like NT, OS/2 is DOS compatible and provides a graphical user interface that lets you run programs with a click of a mouse. OS/2is a PC operating system created by IBM. The advantage of using NT over Windows is that NT makes better use of the PC's memory management capabilities. Unlike the Windows, which runs on top of DOS, Windows NT is an operating system itself. For the best NT performance, you have to use a 486 with about 16 Mb or higher. NT requires a 386 or greater and 8 Mb of RAM. NT is an enhanced version of the popular Microsoft Windows 3.0, 3.1 programs. Windows NT(new technology) is an operating system developed by Microsoft. Each time the DOS developers release a new version, they increase the version number. Over the past decade, DOS has undergone several changes. The version of DOS release in 1981 was 1.0. From the users perspective, PC-DOS and MS-DOS are the same, each providing the same capabilities and commands. When IBM first - \ released the IBM PCin 1981,IBM licensed DOS from "* Microsoft for use on the PC and called it PC-DOS. MS-DOS \ is an abbreviation for «Microsoft DOS». ' DOS is an abbreviation for disk operating system.DOS : was developed by a company named Microsoft. Lastly, the operating system provides several of its own commands that help you to use the computer.ĭOSis the most commonly used PC operating system. The operating system also lets you run programs such as the basic word processor.
They also provide disk management by letting you store information in files. Today, operating systems control and manage the use of hardware devices such as the printer or mouse. With that, the first operating system was born. Programmers soon realized it would be smarter to develop one program that could control the computer's hardware, which others programs could have used when they needed it. The additional program instructions for working with hardware devices were very complex, and time-consuming. When computers were first introduced in the 1940's and 50's, every program written had to provide instructions that told the computer how to use devices such as the printer, how to store information on a disk, as well as how to perform several other tasks not necessarily related to the program.
