Both EPROM and EEPROM are the types of ROM or Read Only Memory, but they are different from each other in many aspects that we will discuss in this article. Let's start with some basics of EPROM and EEPROM so that it becomes easier to understand the differences between them. What is EPROM? EPROM stands for Erasable Programmable Read Only Memory. EPROM is a modern version PROM (or Programmable Read Only Memory). EPROM provides the facility of erasing data stored on it. It uses ultraviolet rays (UV rays) to erase the content stored it. EPROM is built up of ... Read More

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

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 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

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 ...

Data mining is a process of extracting useful information and data patterns from data, whereas a data warehouse is a database management system developed to support the management functions. Read this article to learn more about Data Mining and Data Warehousing and how they are different from each other. What is Data Mining? Data Mining is a process used to determine data patterns and extract useful information from data. It can be understood as a general method to extract useful data from a set of data. In the data mining process, data is analyzed repeatedly to find patterns. Data mining ... Read More

A Fact Table contains a combination of attributes from completely different dimension table. It helps the users understand and analyze the business dimensions that would help improve the business processes. Fact tables are also known as Reality tables.Dimension tables, on the other hand, help a Fact Table gather the dimensions on the data that needs to be collected.Read through this article to find out more about Fact tables and Dimension Tables and how they are different from each other.What is a Fact Table?In data warehousing, a Fact Table is one that contains the measurements, metrics, or facts of a business ...
