In UNIX the file system the file system is a central part of the operating system. The file system is for storage and retrieval of information. Programs that form the UNIX system also stores information in files.
UNIX file systems supports three files namely: ordinary file, directory files, device files or special files.
If we need to access bytes 2500-2503 it means the bytes are within the third block. So we will need only one access.
Note this is because the file control block (inside) is within the memory. If file control block was not in the memory we would have needed more disk accessses.
Answer:
The Encryption solution that best prevents a competitor from receiving confidential information is the SSL(secure Socket Layer) Or TLS(Transport Layer Security).
Explanation:
Solution:
From my own perspective the encryption solution that i will use that prevents s a competitor from receiving confidential information and justify the recommendation is the SSL(secure Socket Layer) Or TLS(Transport Layer Security).
This is because in this case we have to share data confidentially (information need to be hidden from Unauthorized security access. also these provides the Transport Layer security that we needed in above example above.
The purpose of these protocol is to provide server and client authentication, Data confidentiality,and Data integrity (protected from unauthorized change). Application Layer client/server program such as HTTP that uses the service of TCP can encapsulate their data in SSL Packets.
SSL (Secure Socket Layer): is defined as the normal technology for protecting an internet connection secure and defend any sensitive data that is being sent between two systems, and not allowing criminals from reading and changing any information sent, including potential personal details.
TLS (Transport Layer security): It is a procedure that allows data integrity and privacy over Internet communications.
Contemporary pc operating systems and application software use a Graphical User Interface (GUI), which extensively uses icons, buttons, bars, and boxes to perform tasks.
What is a GUI?
A system of interactive visual components for computer software is known as a GUI (Graphical User Interface).
Compared to MS-DOS and the shell of Unix-like operating systems, a GUI is more user-friendly than a text-based command-line interface.
Objects like icons, cursors and buttons are included in a GUI. Sometimes these elements are enhanced with visual effects like transparency and sounds.
