Holds. data, instructions, and information for future use.. A . storage medium . is the physical. material on which data is stored.. Examples. : DVD, CD, flash-drive, and floppy disk.. Storage. Capacity. Reads and writes are equally fast.. Arrays of these disks are used to provide highly reliable storage.. Increasingly popular as they are fast and do not contain moving parts.. Magnetic Disks.. . What is a magnetic disk and how it works. Two main types: Magnetic and Optical. Random access to memory. The hardware must be controlled by driver software called the “controller” in order to be used. Hard Disks, RAID, and Error Handling. Use multiple smaller disks (c.f. one large disk). Parallelism improves performance. Plus extra disk(s) for redundant data storage. Provides fault tolerant storage system. Especially if failed disks can be “hot swapped”. Chapter 8 Adding Disks Loops Run instructions again, and again, and again…. Check some condition If true, repeat 2 types of loops for loop while loop First, the variable used in loop condition must be initialized, then execution of the loop begins. A. G. Zubiría, A. Fragaki, I. Khan. University of Central Lancashire, Preston, Lancashire, PR1 2HE, UK . INRODUCTION. : . Irradiance is fundamental in the energy production of photovoltaic (PV) modules and models can be developed using just irradiance data. However, module temperature has also significant impact on the power output.  In locations with high ambient temperatures PV module performance can be significantly reduced. The aim of this work is to explore ways, using COMSOL Multiphysics®, in which natural ventilation can be enhanced and passive cooling can be achieved at increased wind speeds..
