RAID or Redundant Array of Independent Disk is a set of disk organization techniques developed to increase the reliability and performance of a system. There are various types of RAID techniques such as RAID 0, RAID 1, RAID 2, … RAID 5. Read this article to learn more about RAID 0 and RAID 1 and how they are different from each other. What is RAID 0? RAID 0 stands for Redundant Array of Independent Disk level 0. There is no redundant data stored here, so performance is very good. But the failure of any disk in the array results in loss of data. In RAID 0, ... Read More

In computer systems, different types of memory devices are used to store data permanently. Both SSD and HDD are such storage devices. SSD and HDD are the most commonly used types of secondary memories. HDD is a traditional storage device, while SSD is a modern storage device. SSD and HDD are quite different from each other. The most fundamental difference between SSD and HDD is that SSD (Solid State Drive) is a storage device that stores data in integrated circuits, whereas HDD (Hard Disc Drive) is a device that stores data magnetically. There are several other differences between SSD and ... Read More

Both multiprogramming and multitasking are the concepts related to the operating systems of computer. It is not a good practice that keeping the CPU occupied for a single task only. Since, there is a considerable difference between the speeds of the CPU and other components of the computer system. This difference increases the CPU idle time and degrades its throughput. Therefore, to overcome this problem, several concepts such as multiprogramming, multitasking, multithreading, etc. have been developed to improve the CPU utilization. In this article, we will discuss the important differences between multiprogramming and multitasking. Let's start with some basics ... Read More

In Database Management Systems (DBMS), the ways of designing databases at physical, logical, and view levels are referred to as Data Models. There are two popular data models− the ER Model and the Relational Model. The fundamental difference between the ER Model and the Relational Model is that the ER Model is an entityspecific data model, while the relational model is a table specific model. Read this article to find out more about the ER Model and the Relational Model and how they are different from each other. What is ER Model? ER Model, short for Entity Relationship Model, is ...
