What is the cost of an operating system?

This varies widely from one OS to another. As with many other things it is commonly whatever the market will bear, as in general a computer without an operating system won't do much useful work. However there are opensource OSs (e.g. Linux, OpenVMS) that can be obtained free or at very low cost.


What are examples of an operation system?

You mean an Operating System. Examples include Windows 7, Apple OS X, NeXTSTEP, iOS, Ubuntu, Solaris, Android. Chromium OS, Windows CE, VxWorks, GNU, Mach, NetWare, Plan 9, Palm OS, Domain/OS, VAX VMS, OpenVMS, EXEC-8, VM, Atari TOS, AmigaOS, TRSDOS, UCSD p-System, ISIS-II, CP/M, RSX-11, RT-11, HT-11, DMS, Berkeley Timesharing System, COS, NOS, Multics, z/OS, 360 TOS, 360 DOS, CTSS, BESYS, IBSYS.


What is the most stable operating system?

Stability is difficult to measure in absolutes. A good measurement as to the stability and reliability of an operating system is the record of the highest "uptimes." Uptimes are the length of time a system has been running without the need for a reboot. Note that other factors, such as natural disasters or power outages may have a bearing on uptime not related to stability. The absolute highest uptime recorded is 18 years, by an OpenVMS server. A nicely updated competition of uptimes can be found in the "Related links" below. A rough summary of uptimes, from highest to lowest, is: 1. Linux 2. FreeBSD 3. Windows 4. Mac OS X 5. Sun / Solaris


Can you change the operating system on a computer?

YES, Windows, Linux, etc... you have to first get the CD for the OS you wish to install...then restart your PC and alternate between F9,F11, and delete...this will take you to a screen where you can edit your BIOS...find the boot sequence and change the first one to boot from CD...insert the CD you wish to install and restart your PC...after awhile it should load up the CD and allow you to install the new OS (you can even dual boot if you defrag, learn to split your Hard Drive into partitions, and then get a program such as grub or lilo boot loader).original It would depend on the operating system. Proprietary systems such as Microsoft windows, Z/OS, IBM i, OpenVMS, AIX as well as other licensed UNIX implementations can only be installed and run on the machines for which they were intended and licensed. Anything else will not work because of the differences in the hardware and may also be in violation of the End-User-License. Open source systems such as Linux do not have this problem. It is already available for may hardware platforms and the source code is freely available for anyone interested in implementing it on other machines.


What is the difference between a disk operating system and the Windows operating system?

Disk operating system DOS is a computer operating system using line instruction. For a computer system use disk drive as secondary memory. A Windows system is a computer operating system with Graphic User Interface GUI instead of line instruction. There is no difference between them other than what the vendor or creator wants it to be. A disk operating system is a system based on being run from a disk drive. Typically disk operating systems were single user and single task systems. Predecessors to DOS used cards, magnetic or paper tape as as input, output or main storage device. Successors that relinquished the DOS title had multiprocessing, multiuser, realtime or windowing capabilities and were given other names such as OS/360, RT-11, Windows, multics, unix, linux and more. All modern systems are disk based, unless they use solid state drives (SSD), so all are disk operating systems. Microsoft windows as well as unix, linux, OpenVMS all have a windows interface so they can all be windows operating systems but only microsoft makes that claim.

What is Volume Shadowing openVMS?

Volume Shadowing in OpenVMS is a form of host-based Raid level 1. Essentially two or more identical disk volumes are "mirrored" or "shadowed" resulting in a single "shadow set" volume. Any data written to one disk volume is also automatically written to the others. Shadowing within an OpenVMS Cluster is unique in that the various component volumes of the shadow set can be located on different OpenVMS hosts and even in separate geographical locations. The disk volumes which are members of the shadow set can be single direct-attached disks, RAID-0 stripesets on attached storage controllers or even virtual disk volumes on SAN storage arrays. Additionally, OpenVMS supports booting from shadowed system disks for even greater availability.

The samba software package implements the netbios protocol which is used by Microsoft Windows Lan Manager under TCP/IP to share files. Samba is open software and available free for non-windows platforms such as linux, unix and OpenVMS. Properly configuring samba makes Unix folders appear as shared folders on a Windows system.


Is PHP supported for Alpha machines?

PHP is supported under OpenVMS Alpha 7.3-2 and later (and perhaps earlier as well). There are a few flakes in the package, though, that make it difficult to use properly for some applications, such as running MediaWiki software. PHP comes with the Compaq (now HP) Secure Web Server package, which includes Apache ported to VMS. See the Related Link "HP: CSWB for VMS" for more information.


What does a magnetic tape header label is used to warn the computer operator?

When I worked with DEC/Compaq/HP OpenVMS systems, I wrote a generic routine to read the magnetic tape header information when an operator loaded a tape to be read for a production job. Each tape provider would put a unique label in the header. My routine would return that label which would then be compared to what a known good tape label would be. If it matched, the job proceeded. If not, the operator was given an OpCom message that they had to reply to.
