COMPUTER FUNDAMENTALS

Detailed explanation-1: -The correct answer is Sector. Key Points. There can be more than a thousand tracks on a 3.5-inch hard disk. Sections within each track are called sectors. A sector is the smallest physical storage unit on a disk and is almost always 512 bytes (0.5 kB) in size.

Detailed explanation-2: -while the modern HDDs make use of 4096-byte (4K) size of sector, which is also called advanced format (AF). Besides, there are hard disks of 1024 bytes (1K) sector size. The sector is the smallest unit for data storage.

Detailed explanation-3: -The MBR is sometimes called the partition sector or the master partition table because it includes a table that locates each partition on the storage media or hard disk drive. Other common names include sector zero, master boot block and master partition boot sector.

Detailed explanation-4: -Bits are the basic building blocks of not only data storage, but all computers. Computers work in binary digits, combining 0’s and 1’s in countless patterns. These binary digits are known as bits, and are the smallest possible unit for data storage. When 8 bits are combined, you get a byte.
