When each process request for the resources available in the system, the operating system allocates the needed resources for its execution purpose. The resources allocated can be either a hard drive, scanner, any files in memory, or even a printer. Any program that enters into a ready or execution state is termed a process. This program requires resources from one or other processes to complete its assigned task. In a multiprogramming environment, a process may request multiple resources at the same time, so those processes have to be waiting until it receives all the resources. A resource allocator present in ... Read More

Memory is considered a major part of the operating system to store and access the data. Memory management is a complex task that is performed by the OS when the main memory has limited space and requires more switching operations during multiuser environments. It functions to manage the status of the processes which are in ready, waiting, or execution states and allocates or frees the memory location based on the completion of each process. Each process is allocated to a specific memory location and its status of it is monitored and updated in the memory management system. During a multiprogramming ... Read More

SCSI (Small Computer System Interface) and IDE (Integrated Drive Electronics) are two interface types used to connect storage devices to computers. SCSI is suitable for complicated installations and server environments due to its high performance. IDE is a simpler interface that is largely used to connect internal storage devices to desktop computers. Read this article to find out more about SCSI and IDE and how they are different from each other. What is SCSI? SCSI (Small Computer System Interface) is a series of standards that establish a parallel interface for connecting various peripheral devices to a computer, notably storage devices. ... Read More

Introduction In today's world, data is the backbone of every industry. To make sense of it all, tools like Kibana are used to visualize and analyze the data. However, running Kibana on its own can often lead to performance issues and security vulnerabilities. This is where Nginx reverse proxy comes in handy. Preparing the Environment for Nginx Reverse Proxy Configuration Installing Nginx on the Server Before installing Nginx on the server, it is important to ensure that all necessary dependencies are installed. This can be done by running a system update and then installing the dependencies using the ... Read More

Introduction MongoDB is a popular, open-source NoSQL database that is designed to store and manage unstructured data. It provides high performance, scalability, and flexibility for modern applications. On the other hand, Docker is a containerization platform that enables developers to package their applications and dependencies into portable containers that can run consistently across different environments. It simplifies the software delivery process by providing a lightweight, isolated runtime environment for applications. Setting up the Environment Installing Docker on the local machine Before setting up MongoDB, it's important to install Docker on your local machine. Docker is a containerization platform ...

There has been a rise in researchers and businesses interested in machine learning in recent years. We need computer programs that can analyze data and provide conclusions. Machine learning techniques have applications in many fields, including economics, engineering, and medicine. Machine learning has expanded as both computer software and hardware have improved. In this post, we will examine the RAM needs for machine learning and other specifications. RAM Requirements RAM, or random-access memory, is a computer memory type that allows data to be accessed rapidly. The quantity of RAM required for machine learning is proportional to the data being ... Read More

Files of Mixed Records In DBMS, file organizations are designed to handle records of a single type. However, in most real-world applications, multiple types of entities are interconnected in various ways. To represent relationships among records in different files, fields are connected. For example, a STUDENT record may have a connecting field Major_dept, whose value gives the name of the DEPARTMENT in which the student is majoring. The Major_dept field refers to a DEPARTMENT entity, which should be represented by a record of its own in the DEPARTMENT file. Retrieving field values from two related records requires retrieving one of ... Read More

In this article, we will discuss multimedia databases, its data representation, data storage, data retrieval, data management and applications of multimedia databases. Introduction To store pictures, videos, and sounds that people use for learning, fun, health, and advertising. We need a multimedia database. A multimedia database has all kinds of information, like words, pictures, sounds, and videos. It keeps track of all this information and finds data easily. These databases enable the storage and retrieval of multimedia data components. All media files in these databases are stored as binary strings and encoded according to their file types. Let's explore the ... Read More

The concept of deferred update in database management systems (DBMS) involves postponing the actual updates to the database on disk until a transaction successfully completes its execution and reaches the commit point. During the execution of a transaction, updates are only recorded in the log and in the cache buffers. Once the transaction reaches its commit point and the log is forcefully written to disk, the updates are then recorded in the database. If a transaction fails before reaching its commit point, there is no need to undo any operations because the database on disk remains unaffected. As a result, ... Read More
