Main HTML tags

Hello, welcome back. In my last blog, I told you the basics of HTML. Now, I am going to go into a little depth about each tag in HTML. HTML tag HTML tag is the first tag to be written.

Storage devices in detail

Hello, welcome back. In my last blog, I told you the basics of storage devices. Now, I am going to go into a little depth about each type of storage devices. Optical storage Optical storage is the storage of data on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light, usually, a beam of laser light precisely focused on a spinning optical disc. An older example of optical storage that does not require the use of computers, is microform. There are other means of optically storing data and new methods are in development. An optical disc drive is a device in a computer that can read CD-ROMs or other optical discs, such as DVDs and Blu-ray discs. Optical storage differs from other data storage techniques that make use of other technologies such as magnetism, such as floppy disks and hard disks, or s...

Introduction to storage devices

TYPES OF STORAGE DEVICES Magnetic storage devices A magnetic storage device is a storage device that stores data using tiny magnetised dots. These dots are created, read and erased using tiny electromagnets. Examples: Hard disk (magnetic disc) magnetic tape floppy disc etc... Optical storage devices An optical storage device is a storage device that stores data using a laser beam. Holes are formed in the storage medium (device) that are read using a laser beam. Examples: CD disc DVD disc Blu-ray disc etc... Solid-state storage devices A solid-state storage device is a storage device that stores data using no moving parts. It uses flash memory. This is the same tech used in USBs. Examples: USB memory stick Smart cards SD cards etc... Thank you for reading. Stay tuned to find out more! Ple...
