FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A disk read-and-write head is the small part of a disk drive which moves above the disk platter and transforms the platter’s magnetic field into electrical current (reads the disk) or, vice versa, transforms electrical current into magnetic field (writes the disk).

Detailed explanation-2: -The mechanical arm is used to read from and write to the disk. The data on a magnetic disk is read and written using a magnetization process. The platter keeps spinning at high speed while the head of the arm moves across its surface. Since the whole device is hermetically sealed, the head floats on a thin film of air.

Detailed explanation-3: -A read/write head is a specific physical part of a hard disk that is responsible for reading data from, and writing data to, the disk. Read/write heads are typically made up of a thin horizontal magnetic blade attached to an actuator arm.

Detailed explanation-4: -The hard drive contains a spinning platter with a thin magnetic coating. A “head” moves over the platter, writing 0’s and 1’s as tiny areas of magnetic North or South on the platter. To read the data back, the head goes to the same spot, notices the North and South spots flying by, and so deduces the stored 0’s and 1’s.

Detailed explanation-5: -The Brainstem: Middle of the Brain Think of the brainstem like a computer hard-drive. It is the body’s main control panel and is responsible for conveying messages between the brain and other parts of the body.
