This paper presents the overview of existing approaches for scheduling the real- time transactions. Earliest Deadline First (EDF) is a basic algorithm which meets the real time constraints, but it gives poor disk throughput. Adaptive Earliest Deadline (AED) improves the performance ...
It is like to the SCAN disk scheduling algorithm but the change that the disk arm in spite of going to the end of the disk goes only to the last demand to be checked in front of the head and then backs its direction from there only. Therefore, it avoids the additional postponement whi...
Because the modified deadlines were smaller than the original ones, number of tasks that could be rescheduled is decreased and thus data throughput is reduced. In this paper, we propose Reschedulable-Group-SCAN (RG-SCAN), a new real-time disk scheduling algorithm using the concept of Re...
As Vista itself, Vista defrag is already good but it seems like scheduling logic did not change i Windows 7. Kind of: it won't work for my mom who at the same time really needs defrag and does not leave your PC turned on at 1:00 AM!
In this section, we discuss data layout and access scheduling in order to better understand the issues. We begin with data layout, and then move on to scheduling. We will use a sequence of design approaches in order to unveil fundamental problems. These will later be addressed in our ...
And because of a full scan, it takes higher computer resources to perform its task. So, by scheduling the system you can reduce the number of files to scan by windows defender instead of scanning the full system. And here is how you do it… ...

In these disk-scheduling controllers the request queue may be kept in an elevator queue (the requests are ordered as a function of sector radial distance) with each request identified by its associated handle. However, for inexpensive disk drives with an IDE (ATA) or SCSI interface, as would...
A disk scheduling system with bounded request reordering. Disk access requests may be performed during traversals of a disk head across a disk. Each traversal may have a specified direction of motion.
