CS/IS 101 Lecture Notes - Lecture 10: Kilobyte, Hard Disk Drive, Nvm Express
Document Summary
Hard drives are composed of blocks that are formed of bytes. Logical block addressing (lba) a controller circuitry that, with the help of software, acts as an interface between the operating system and the storage device. free blocks. If the os wants to save a file, it goes to the lba so it can store it in one of the. It"s basically the device driver for the hard drives. Because the lba exists in every os, it makes hard drives basically plug-and- Regardless of the media your operating system sees mass storage as a string of. Capacity sizes in ascending order: kilobyte -> megabtyes -> gigabytes -> terabytes -> logical block addresses. 2^x = is the number of blocks in a hard drive. X values: 10 = kebi, 20 = mebi, 30 = gibi, 40 = tebi, 50 = pebi, 60 = There is a difference between decimal values and iec values.
