Grade 9 has completed studying storage devices and media. We explored the storage devices in three categories i.e. magnetic storage, optical media and solid state memory.
Students can distinguish between magnetic tapes and magnetic hard disks which are used for backup and secondary storage. Comparing and contrasting optical devices such as CD/DVD-R, CD/DVD-RW and CD/DVD-ROM allowed students to understand different uses of them such as copying files, burning audio discs, installing software, running video game and watching movies.We also checked various types of solid state memory like pen drive, flash memory and sim cards.
