This document discusses physical storage media and file organization in a database system. It describes different types of storage media like magnetic disks, flash memory, and tape storage. It explains the hierarchy of storage from fastest but volatile primary storage to slower but non-volatile secondary and tertiary storage. The document also discusses techniques for improving performance and reliability of disk storage, including RAID (Redundant Arrays of Independent Disks) and how it uses data striping and redundancy across multiple disks to provide improved I/O performance and fault tolerance. It outlines several RAID levels that trade off performance, reliability, and cost in different ways.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
