Which operating system is responsible for interacting with hardware?
All operating systems interact with hardware.
Which computer device has operating system?
An operating system is a set of instructions running in a program that provides basic operation of the hardware of the computer and presents it in a command line or graphical user interface to the user in such a way they can interact with it and use it to perform some kind of work.
Basically it manages the resources of computers and it's hardware for the user.
Hope this helps!
Is compiler a part of operating system?
compiler basically translator of one language to desired languages...ex-c language to m/c redable format and os is a system software which provides interfaces between applicaton programs and hardware....so os is a interface unit system software and compiler just a translator....
1- State of current process is Saved.
2-Restore State of incoming process.
What operating system did Linus Torvalds create?
An operating system is usually defined as a collection of software used to create a complete and usable system. By that definition, he did not create any operating system. Torvalds created the most important piece of an operating system, a kernel. The kernel he created is called Linux.
What do you call the option in the Configure Screens Menu?
What is the final option in the configure screen menu
Explain process control block?
The Process Control Block acts as a library of information about the processes in a system. Specific information is stored in the process control block highlighting important information about each process.
What software enables an attached device to communicate with the computers operating system?
it's called device driver software commonly called a driver
An expert system is a program that asks specific questions to get answers to a question like an "expert" would give.
EG: An expert on diseasses will ask you what syptons u have until u get down to what disease u have been getting last Friday money pie donkley.
What is the kernel file normally named?
It varies from system to system, based on what the distributors call it and if you run a custom kernel or not, but the file will usually at least have vmlinuz as part of the name. This means it runs on its own virtual machine and is compressed.
Also, there will likely be a ramdisk image accompanying the kernel that will contain necessary drivers and configuration files for the kernel to be able to read and run what's on your hard disk.
Remember that the kernel file is an IMAGE, not an executable binary. That means its meant to basically be copied straight into memory unmodified and manipulated from there before execution. You, the user will not be able to modify it very easily. IF your goal is a custom kernel, then get the source code for the kernel, introduce your patches, do your configuration, and build it.
If your goal is in seeing what the kernel is "thinking" at any point in time, you'd be best looking at the contents of the /proc and /sys directories, which give you a peek into the innards of the systems current operation, as they are virtual filesystems that base themselves off of the current state of the kernel. You can also normally grab your current kernel's configuration by copying out /proc/config.gz and decompressing it. It will be a plaintext file you can read and write.
What is the difference between online spooling and offline spooling?
in off line spooling user has no interface with systems it strongly used in Batch system's.it mean's that you submit your request to system , system will cmputing and print result of request without interface with user.
What is Multiprogrammed Batch System in Operating System?
No. Linux can have several tasks and split resources between them. Linux would be considered a time-sharing system.
Generally, it will be single-user, single tasking.
What is difference and similar between loosely-coupled system and tightly-coupled system?
The way I understand it is, that tightly coupled architecture does not provide a lot of flexibility for change when compared to loosely coupled architecture.
For eg., if two disparate systems exchange messages, the message format has to be the same if they are tightly coupled. If the source uses java, the receiver should be able to read the message using java. Also, if any change is made is made to the source or the receiver systems, the other end has to be modified appropriately.
But in case of loosely coupled architectures, message formats or operating platforms or revamping the business logic does not impact the other end. If the system is taken down for a revamp, of course the other end will not be able to access the service for a while but other than that, the unchanged end can resume message exchange as it was before the revamp.
Give 5 real life example of stacks?
a) The processing of procedure calls and their terminations in computer programming. b) Arrangement of granules in chlorophylls. c) Arrangement of Plates on over another. The plate at the bottom of the plate hype is washed and kept first but, it is used or comes out last. d) Chapattis cooked first are placed at the bottom in the Tiffin and the last cooked id at the top in the Tiffin. e) Arrangement of chairs on over another. The chair which is put in first lies last when comes out.
How Operating system functions?
A process is an environment in which a program executes. They run in the background and provide a common language that allows the operating system to interface with the installed hardware & software to support any applications running on the system.
A process is simply a group of code in memory. It is a collective task grouping that accomplishes one particular need. It is an active program entry that has its state and context, a share of resources such as memory, registers and others.
It is sequence of microoperations that run and perform one job, and a well defined context at which instant it is executing the task. A process is an active program entry that takes a part of CPU. For more detail, study OS fundamentals in nearly any OS book.
What is one type of operating system?
The different types of operating system are as follows:-
Real-time Operating System: It is a multitasking operating system that aims at executing real-time applications. Real-time operating systems often use specialized scheduling algorithms so that they can achieve a deterministic nature of behavior. The main object of real-time operating systems is their quick and predictable response to events. They either have an event-driven or a time-sharing design. An event-driven system switches between tasks based of their priorities while time-sharing operating systems switch tasks based on clock interrupts.
Multi-user and Single-user Operating Systems: The operating systems of this type allow a multiple users to access a computer system concurrently. Time-sharing system can be classified as multi-user systems as they enable a multiple user access to a computer through the sharing of time. Single-user operating systems, as opposed to a multi-user operating system, are usable by a single user at a time. Being able to have multiple accounts on a Windows operating system does not make it a multi-user system. Rather, only the network administrator is the real user. But for a Unix-like operating system, it is possible for two users to login at a time and this capability of the OS makes it a multi-user operating system.
Multi-tasking and Single-tasking Operating Systems: When a single program is allowed to run at a time, the system is grouped under a single-tasking system, while in case the operating system allows the execution of multiple tasks at one time, it is classified as a multi-tasking operating system. Multi-tasking can be of two types namely, pre-emptive or co-operative. In pre-emptive multitasking, the operating system slices the CPU time and dedicates one slot to each of the programs. Unix-like operating systems such as Solaris and Linux support pre-emptive multitasking. Cooperative multitasking is achieved by relying on each process to give time to the other processes in a defined manner. MS Windows prior to Windows 95 used to support cooperative multitasking.
Distributed Operating System: An operating system that manages a group of independent computers and makes them appear to be a single computer is known as a distributed operating system. The development of networked computers that could be linked and communicate with each other, gave rise to distributed computing. Distributed computations are carried out on more than one machine. When computers in a group work in cooperation, they make a distributed system.
Embedded System: The operating systems designed for being used in embedded computer systems are known as embedded operating systems. They are designed to operate on small machines like PDAs with less autonomy. They are able to operate with a limited number of resources. They are very compact and extremely efficient by design. Windows CE, FreeBSD and Minix 3 are some examples of embedded operating systems.
What is a closed source operating system?
An OS where the source code isn't released to the public. Windows and Mac are 2 examples.
What are non preemptive scheduling algorithms?
Strictly speaking, nonpreemptive scheduling is when the scheduler does not stop the process from running in order to switch it with a different process, but instead, it lets the process to complete and then schedules a different process depending on the a scheduling algorithm is uses.
How do you use a computer without a mouse?
You can use your keyboard instead of a mouse. This is done by a number of keys.
The tab key - this will move from link to link on a web page.
The ALT key - A example being on a web page, up at the top above the address bar, you will see File, Edit, View etc. Under each of these headings, one letter has a underline underneath it. File is F, Edit is E etc. The alt key, allows you to use which ever key is underlined to access the other drop down menu's. Each of these will also have a letter underlined, to access other options.
The arrow keys will allow you to do pretty much the same thing.
Control with a letter. example, instead of right clicking and copy, do Control C.
Instead of right click, and paste. Do control V
Instead of going to file, print, do control P.
Instead of right click and cut, do control X.
There are a number of different keys which can be used with the control key.
Hope this helps
Be safe
