The answer is FALSE because the interior of commercial Hard disk drive is with stack of magnetic disks (platters) containing the user’s data and a rotating arm supporting the magnetic heads. The rotating arm is moved by the torque generated by a voice coil motor (VCM) mounted at one end of the arm. Data read/write operations rely on the capability of the governing unit of the HDD to maintain the magnetic read/write heads as close as possible to center of the desired track. Typically, reliability of data reading and writing is guaranteed when the head is kept within 5% of the track pitch from the track center. This means that the accuracy required for the head positioning is in the range of a few tens of nanometers.

Explanation:

Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.

Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

Hence, SSH, HTTPS and SMTP are considered as secure network protocols.

HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).

SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.
