RAID stands for Redundant Array of Independent Disks. It is a data storage technology that combines multiple physical disk drives into a single logical unit for improved performance, fault tolerance, and data protection.

• RAID is used to increase storage capacity, improve performance, and provide data redundancy.

• There are different RAID levels, such as RAID 0, RAID 1, RAID 5, RAID 10, etc., each offering different benefi...read more

RAID 4 was needed to improve performance and address the bottleneck issue of RAID 3.

• RAID 4 allows for parallel access to multiple disks, improving performance.

• RAID 3 had a single dedicated parity disk, causing a bottleneck in write operations.

• RAID 4 introduced independent block-level striping with a dedicated parity disk.

• The change from RAID 3 to RAID 4 aimed to distribute the parity calculations across all disks.

• RAID ...read more

Parity bits are used in computer systems to detect errors in data transmission.

• Parity bits are extra bits added to a binary code to make the total number of 1s either even or odd.

• They are used to detect errors during data transmission by comparing the number of 1s in a code with the expected parity.

• If the number of 1s doesn't match the expected parity, an error is detected.

• Parity bits can be even parity (total number o...read more

Parity bits can be detected by checking for errors in the parity bit itself or by comparing the parity bit with the data it is supposed to protect.

• Check for errors in the parity bit itself

• Compare the parity bit with the data it is supposed to protect

A simple code for implementing a linked list.

• A linked list is a data structure where each element contains a reference to the next element.

• The last element points to null.

• Operations on a linked list include insertion, deletion, and traversal.

• Example code: class Node { int data; Node next; }
