What is an operating system interface?
It is a set of commands or actions that an operating system can perform and a way for a program or person to activate them.
What operating system does relational database use?
Relational databases can be run on almost all modern operating systems, including Windows, Linux, FreeBSD, and Mac OS X.
OS stands for Operating System, so on a PC it would be Windows, on an Apple it would be Mac. (Please re-phrase your question if this did not answer it.)
•No special support needed from the kernel (use any Unix)
•Thread creation and context switch are fast (no syscall)
•Defines its own thread model and scheduling policies
Command system is when the government makes decisions or when the economic decision is taken by the central body. This type of system contrasts the market economy.
Are most operating systems today designed for either 16-bit or 32-bit CPUs?
Most operating systems are designed for either 32-bit or 64bit CPU's.
What is clustered system operating system?
A clustered system is two or more computers that share access to each other's disk storage or to a separate storage system(s). This can include satellite systems without any hard drive storage that boot and run completely using another machines hard drive. Clusters may be connected using special high speed channels such as Fiber to support the hard drive traffic. They may also use LAN connections for data transfers. Various LAN protocols are available TCPI/IP such as NFS (network file system), and SMB/CIFS (Server Message Block/Common Internet File System) often interchangeably called NetBIOS, Lan Manager and Samba. Other clustering methods include proprietary clustering protocols, Decnet, LAT, and NetBEUI
Clustering (means gather together) allows two or more system to shear storage closely linked via a local area network .
- Provide high reliability ( Its work never stopped).
- Asymmetric Cluster (at least two servers: One is on a standby mode while the other is monitoring the other one. If one stops other will work).
- Symmetric Cluster (all work with one: The work together and monitor each other).
Can you install an operating system on a USB Flash drive?
There is no reason you cannot load an operating system on a flash drive. However, getting the computer to recognize the flash drive and boot from it could be an issue.
In many ways, computer hardware and operating systems grow together - changes in hardware have to be accomodated by changes in the operating system to support them, conversely the way the operating system uses the hardware may well influence hardware designers to improve aspects of their work.
Example
When Windows XP was released, DVD writers were fairly rare and expensive devices and XP did not directly support them; third party writing software had to be used. When Vista was released, the operating system accomodated the new hardware.
Conversely, Windows computers rely heavily on DirectX technology for graphics. Video adaptor designers specifically try to make their devices so they run DirectX well.
Computer companies such as IBM and Apple produce both the computer and the operating systems, so they can more tightly couple the two together for simpler operation.
Email is not a real time communication system?
Yes When you send an email, · When it will arrive at its destination. · When the recipient will get round to reading it. · When the recipient will start to reply to it. · How long they will take to write and send their reply, · How long that reply will take back to you. Five unknown times, each of which suffices to make it non real time
What is the operating system of graphic tablet?
operating system of graphic tablet is some systems which operate the graphic tablet
simple..................................................................................................
Case sensitive operating system?
Operating systems can be case sensitive in the way you give them command. Many OSs will not accept the commands if you change capitalization. It is more seen in command line OSs.
How can you tell if a PC has ddr or ddr2 ram installed?
Surf to Crucial .com and they will scan your computer for free.
Is DOS a multitasking operating system or not?
DOS by default is not capable of multi-tasking. However, there are some shell and TSRs designed to allow you to switch between different DOS apps.
Which programming language is used to develop Linux operating system?
C, C++ and scripts in Bash, Perl and Python
Does driver software is an system software?
No, Driver Software is Software made for any Device and not for the system . Like any Computer having Realtek Sound Adapter on its MotherBoard so they will provide a setup which is a Device Driver Software . Eventually Operating System Dont have the commands and any programming to control the Device so the Device Manufacturer provides the Commands and services via device Driver Software or setup .
You cant Actually see that every Device got different Softwre for Different Operating System and Device Version. Like same Realtek Device would have made the Device Driver for Windows as well as Linux or other Avalable Operating System with which it is compatible .
Blue screen errors happen when which type of processes encounter an error?
Blue screen errors, officially known as BSOD (Blue Screen of Death) happen when a critical system process, function or file is lost. This is caused by files in the Operating System being deleted. Also, BSOD can happen if you hold down the power button too long on your laptop when shutting down and can corrupt data caused by too much voltage being circulated through the machine.
What are all the examples of operating systems?
There are too many to list, but it starts with DOS and Windows for Intel chips and Mac OS for 68000 chips. Unix has been adapted for both and for non-standard chip sets as well. They all have at least a dozen variations.
Can you use a restore CD from another computer to install an upgraded operating system?
Yes, you can. But sometimes you might a problem because if that CD which you are going CD was provided by manufacture it will work mostly with computers from the manufacture.
What is the difference between an abstract system and a physical system?
Physical systems are tangible entities that may be static or dynamic in operation. For Example, the physical parts of the computer center are the offices, desks, and chairs that facilitate operation of the computer. They can be seen and counted, they are static. In contrast, programmed computer is a dynamic system. Data, programs, output and application changes as the user's demand or the priority of the inforamation requested changes.
Abstract systems are conceptual or nonphysical entities. They may be models-the abstract conceptualization of physical situations. A model is a representation of a real or a planned system. The use of models makes it easier for the analyst to visualize relationships in the system under study. The objective is to point out the significant element and the key interrelationships of a complex system.
What is the operating system or systems software?
Operating system act like a manager between the system hardware and application software (Such as Firefox)
Also they do the fallowing tasks
- CPU scheduling
- Memory management
- Inter-process communication
What is the relationship between a guest Operating System and a host system in a system like VMware?
It is both operating system....
