The concept of a NOS is still used for some networking devices, such as routers, switches and firewalls, and manufacturers may employ proprietary NOSes, including Cisco Internetwork Operating System (IOS), RouterOS and ZyNOS. O D. Voltage is a type of pressure that can direct electricity to flow. Which of the following statements is true about operating systems for computers. Fragmentation is of two types −. The operating system allows the users to share the computer simultaneously. Shortest remaining time (SRT) is the preemptive version of the SJN algorithm. As an example, a Windows API can enable a program to obtain input from a keyboard or mouse; create GUI elements, such as dialog windows and buttons; read and write files to a storage device; and more. Create a tailored training plan based on the knowledge you already possess. This code represents a single process, executes in single address space and do not require any context switch and hence is very efficient and fast.

Distributed Environment. Thread switching does not need to interact with operating system. It is also called as CPU scheduler. 1 workstation seems to be having issues with the operating system. The /S switch is used to specify a remote system, and the /FI switch applies a filter to a set of tasks. To make compaction feasible, relocation should be dynamic. Some portion of memory is left unused, as it cannot be used by another process. A data structure called page map table is used to keep track of the relation between a page of a process to a frame in physical memory. Have all the properties of a class C2 system. Which of the following statements about an operating system is FALSE. Shortest Remaining Time. Impossible to implement in interactive systems where required CPU time is not known. 6||In multiple processes each process operates independently of the others.
The printer is online and connected. This access method is the most primitive one. The OS defines a job which has predefined sequence of commands, programs and data as a single unit. The processors communicate with one another through various communication lines (such as high-speed buses or telephone lines). An optimal page-replacement algorithm has the lowest page-fault rate of all algorithms. Solved] Which of the following statements is always true about the... | Course Hero. Index is searched sequentially and its pointer is used to access the file directly. You can still buy Windows 7 and install it, but you will need to do a clean installation instead (in other words, you won't be able to keep your existing files unless you back them up and restore them).
