yes shiraz yes
Yes; without it your computer might as well be a giant paperweight! Without software hardware is useless.

What is load time in operating system?
How long it takes after you turn the computer on to be able to use it.
How does the operating system of a computer manage the computers resources?
One of the main things the operating system manages is the memory. The operating system contains a memory manager, dispenses memory to applications, and keeps track of what is used. It also consolidates and defragments the memory and returns relinquished memory back to the pool of available memory.
The operating system uses drivers to match itself to the exact hardware that is in the system and to provide ways to use and manage the hardware.
The operating system uses the storage drivers to provide APIs to manage disk I/O, and it uses file system drivers to manage the file systems needed to store files.
List three functions of an operating system?

What is difference between distributed operating system and operating system?
Distributed computing is decentralised and parallel computing, using two or more computers communicating over a network to accomplish a common objective or task. The types of hardware, programming languages, operating systems and other resources may vary drastically. It is similar to computer clustering with the main difference being a wide geographic dispersion of the resources. An operating system (OS) is a software program that manages the hardware and software resources of a computer. A key component of system software, the OS performs basic tasks, such as controlling and allocating memory, prioritizing the processing of instructions, controlling input and output devices, facilitating networking, and managing files.
Concurrent process uses of operating system?
processes are concurrent if they exist at the same time.concurrent process can function completely indepently to one another.
two process are concurrent if their execution can overlap in time; that is, the execution of the secon process starts before the first process completes.
concurrent processes generally interact through the following mechanisms:
Shared variables
Message passing
Process of installation repair and maintenance electrical systems?
Electrical basics Get a job with someone knowledgeable, as a helper, for about five years, attend electrical classes at night, read every technical manual you can secure and learn the various electrical codes.
That should provide a rudimentary understanding of what is required.

Which IDS method is operating system dependent?
The IDS method that is operating system dependent is Network Based
Is unix is multiprogramming OS?

Should operating systems include applications such as Web browsers?
A consumer operating system would probably be quite useless in this day and age without a web browser. A web browser, or at least some method of installing one, should be made readily available to all users. The main complaints about Microsoft doing so were mostly because they made it impossible to uninstall the web browser, and made it too integrated into the rest of the system, increasing security vulnerabilities.
Advantages and limitations of batch operating system?
it is efficient from the computer's point of view but each job wait in line at each step and often increases its turn around time.
What type of operating system is used in railway reservation?
As of 2008. Many of the major rail reservations systems in Europe use a HP NonStop based reservations system including all the rail operating companies in the UK. France SNCF uses an IBM TPF system as does Italy. Other options include HP Open/VMS and some Unix systems. The only actual passenger rail in the US is Amtrak and they have a reservation system that runs on IBM's TPF and the application had its early beginnings from Braniff Airlines and its IBM PARS system.
