In computer networks, links are the pointers associated with files and directories. These links are of two types: Hard Links and Soft Links. A hard link is a direct reference to a file, while a soft link is a reference by name. Thus, a soft link points to a file by its file name. Read this article to find out more about hard links and soft links and how they are different from each other. Let's start with a basic overview of hard links and soft links so that it becomes easier to differentiate them. What is a Hard Link? The ... Read More

In a computer system, memory devices are used to store data and information. Computer memories are mainly classified into three types – primary memory, secondary memory, and cache memory. The primary memory is further classified into two types namely – RAM and ROM, where RAM is further subdivided into two types, i.e., SRAM and DRAM. Read through this article to find out how an SRAM is different from a DRAM. What is RAM? RAM stands for Random Access Memory. It is the internal memory of the CPU for storing data, program, and program result. It is a read/write memory ... Read More

A program is a passive entity that has a set of codes and instructions required to accomplish a task. A process, on the other hand, is an active entity of a program that is started with the execution of the program. Thus, the process is started by the program, once it is executed. The instructions of the program are then executed by the process. Read through this article to find out more about programs and processes and how they are different from each other. What is a Program? A program is a set of instruction codes that has been designed ... Read More

In computers and other electronic devices, there is an internal storage device called ROM (Read Only Memory). It is a storage device used to store data and instructions permanently. Till date, there are several types of ROMs available such as PROM, EPROM, and EEPROM. There are several differences among all these types of ROMs depending on the manufacturing process, electronic components used, operation, reversibility, etc. In this article, we will discuss the important differences between PROM and EPROM by considering different parameters. But before that, it is important to get an overview of their basics so that it becomes easier ... Read More

In computer parlance, security and protection are the two terms that seem similar at first glance. Therefore, most people use them interchangeably, but both are quite different from each other. In this article, we will highlight how "security" is different from "protection". Basically, the measures to prevent the interference with use of local and physical resources of computer systems provided by the operating system are known as security and protection. One major difference between security and protection is that security deals with the external threats on the information, while protection handles the internal threats on the information. Before going ... Read More

File System provides a way to organize files and to manage the drives in the computer systems. File system basically specifies how data will be stored in a form of file and folders. It provides the Metadata about the files like name, permission, size and other attributes. There are two popular file systems namely, FAT32 and NTFS, used in the Windows Operating System. Read this article to learn more about FAT32 and NTFS and how these two file systems are different from each other What is FAT32? FAT32 stands for File Allocation Table 32. It is the oldest of ...

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 ...
