What accepts logical io requests from application programs or other operating system modules translates them into physical io commands and passes the phsicsal commands to what?
MSDOS.SYS accepts logical io requests from application programsor other operating system modules translates them into physical io commands and passes the phsicsal commands to IO.SYS
What is the special code that prioritizes service requests from the operating system?
A special numerical code that prioritizes device requests from the operating system is called
Which server type is likely to require the greatest storage capacity?
For a high availability application, you’re going to want to choose your server type carefully. Generally, the larger the number of processors and cores on a server storage, the faster it will respond to client requests. A multi-core processor of a Lenovo laptop can handle multiple requests simultaneously instead of waiting for one in the queue before responding to another request.
What requests information from a web server?
An application or browser
How does a networked server manage requests from multiple clients for different services?
The applications installed help the networked server manage requests from multiple clients for different services. The server receives the requests and delegates them.
What is the difference between multitasking multiprogramming and multithreading?
Multiprogramming is a rudimentary form of parallel processing in which several programs are run at the same time on a uniprocessor.Since there is only one processor, there can be no true simultaneous execution of different programs. Instead, the operating system executes part of one program, then part of another, and so on. To the user it appears that all programs are executing at the same time. Multitasking, in an operating system, is allowing a user to perform more than one computer task (such as the operation of an application program) at a time. The operating system is able to keep track of where you are in these tasks and go from one to the other without losing information Multithreading is the ability of a program or an operating system process to manage its use by more than one user at a time and to even manage multiple requests by the same user without having to have multiple copies of the program running in the computer
If the processor requests something from a device and the device is not ready the device issues a?
wait state!! :)
What are the task performed by Database management system?
1. it helps each application program to be executed in a sequence. 2. it requests the operating systems to execute an input operation. 3. it provides status information to the application program. 4. It processes data. - RIYA G.
What does an operating system control?
An operating system takes control by effectively managing user input. It also manages both external and internal requests. This can include program and application requests, along with information sent via keystrokes and other protocols. The main function of any operating system is to assist the CPU in facilitating user and program functions.
What is memory contention?
Memory contention is a state a OS memory manager can reside in when to many memory requests (alloc, realloc, free) are issued to it from an active application possibly leading to a DOS condition specific to that application. Memory contention is typically not caused by a memory overflow by all joined allocation requests but rather by the frequency of joined reallocation requests issued! Is is not about the joined memory size allocated but about the reallocation request queue size that overflows! A typical symptom of an application suffering memory contention and therefore not anymore being served memory management requests by the operating system, is that it unexpectedly shuts down without any form of notification.
What function does a server have?
Server's function is to respond for the client's application requests
What happens if multiple connection requests arrive at about the same time at the server?
Servers are deigned to handle multiple connection requests. Depending on the service, for each request a socket or thread is opened.
