Operating Systems

An operating system, or OS, is a software program that enables the computer hardware to communicate and operate with the computer software. Without a computer operating system, a computer would be useless. Operating system types As computers have progressed and developed so have the operating systems. Below is a basic list of the different operating systems and a few examples of operating systems that fall into each of the categories. Many computer operating systems will fall into more than one of the below categories.

GUI – Short for Graphical User Interface, a GUI Operating System contains graphics and icons and is commonly navigated by using a computer mouse. See the GUI definition for a complete definition. Below are some examples of GUI Operating Systems.

Colorsync 3. 0 – Manages color even more efficiently. Synchronize – Synchronizes with Palm computing products using HotSync software. TCP/IP – Provides access to TCP/IP networks. Lock System – Ensures that System Folders and Applications do not accidentally get reconfigured by having the capability of locking the system. Windows 98 Windows 98 overview Microsoft Windows 98 is the upgrade to Microsoft Windows.

While this was ot as big as release as Windows 95, Windows 98 has significant updates, fixes and support for new peripherals. Below is a list of some of its new features.

Windows CE Multi-user – A multi-user operating system allows for multiple users to use the same computer at the same time and different times. See the multi-user definition for a complete definition for a complete definition.

Below are some examples of multi-user operating systems. Linux- Developed by Linus Torvalds and further elaborated by a number of developers throughout the world, Linux (lee’nuhks/ or /li’nuks/,_not_/li:’nuhks) is a freely available multitasking and multiuser operating system. From the outset, Linux was placed under General Public License (GPL). The system can be distributed, used and expanded free of charge. In this way, developers have access to all the source codes, thus being able to integrate new functions or to find and eliminate programming bugs quickly.

Thereby drivers for new adapters (SCSI controller, graphics cards, etc. ) can be integrated very rapidly. Unix- Unix ABCs Unix, which is not an acronym, was developed by some of the members of the Multics team at the bell labs starting in the late 1960’s by many of the same people who helped create the C programming language. The Unix today, however, is not just the work of a couple of programmers. Many other organizations, institutes and various other individuals contributed significant additions to the system we now know today. Windows 2000

Windows 2000 is based of the Windows NT Kernel and is sometimes referred to as Windows NT 5. 0. Windows 2000 contains over 29 Million lines of code, mainly written in C++. 8 Million of those lines alone are written for drivers. Currently, Windows 2000 is by far one of the largest commercial projects ever built. Some of the significant features of Windows 2000 Professional are: •Support for FAT16, FAT32 and NTFS. •Increased uptime of the system and significantly fewer OS reboot scenarios. •Windows Installer tracks applications and recognizes and replaces missing components. Protects memory of individual apps and processes to avoid a single app bringing the system down. •Encrypted File Systems protects sensitive data. •Secure Virtual Private Networking (VPN) supports tunneling in to private LAN over public Internet. •Personalized menus adapt to the way you work. •Multilingual version allows for User Interface and help to switch, based on logon. •Includes broader support for high-speed networking devices, including Native ATM and cable modems. •Supports Universal Serial Bus (USB) and IEEE 1394 for greater bandwidth devices.

Multiprocessing – An operating system capable of supporting and utilizing more than one computer processor. Below are some examples of multiprocessing operating systems. Linux Unix Windows 2000 Multitasking – An operating system that is capable of allowing multiple software processes to run at the same time. Below are some examples of multitasking operating systems. Unix Windows 2000 Multithreading – Operating systems that allow different parts of a software program to run concurrently. Operating systems that would fall into this category are: Linux Unix Windows 2000 OPERATING SYSTEM LISTING
