An admin dashboard provides important data insights and controls for managing various aspects of an application or website. In this article, we will explore the process of creating a responsive admin dashboard using the three pillars of web development: HTML, CSS, and JavaScript. Prerequisites To follow this article, you should have a basic understanding of HTML, CSS, and JavaScript. Familiarity with concepts like responsive design, CSS Flexbox, and CSS Grid will also be helpful. Step 1: Setting Up the HTML Structure We'll start by setting up the basic HTML structure for our admin dashboard. Create a new HTML ... Read More
In the Operating System, the requests from the input or output of the programs or applications are handled by Disk scheduling algorithms. The System receives countless numbers of requests from different programs and only one request can be processed at a time by the system and all other requests has to wait in queue. The major work of disk scheduling is to increase the performance of the system by reducing seek time, rotating latency, and transfer time. For these processes, different algorithms are used and one among them is SCAN (Elevator). Scan Disk Scheduling Algorithm The Scan Disk Scheduling algorithm ... Read More
Scheduling algorithms of the operating system are used for scheduling the input process to the respective processor. The process scheduler has the allocation rights to decide on which process to start its execution based on any one of the scheduling algorithms. Any process in the execution state that uses CPU resources can be preempted and other process in the ready queue is chosen for execution based on priority, in terms of priority-based algorithms. Preemptive algorithms provide access to the CPU to the process which has higher priority, and preempt if any other process which is already running with lower priority. ... Read More
Raymond’s tree-based algorithm is used to protect the distributed systems from the occurrence of sections by the lock method. Distributed systems are networks with numerous numbers of nodes that involves the message flow from one node to another. When the process is locked or in the critical section, then only one thread or process can be allowed inside and other threads will be in the waiting state. As there are many nodes involved in the distributed systems, it can be reduced by spanning trees.Raymond’s Tree Based Algorithm Definition The Algorithm follows the method that only the threads with tokens are ...

In Python, the concatenation of strings is a common operation that allows you to combine two or more strings into a single string. While concatenating strings vertically (i.e., one below the other) is straightforward, concatenating strings horizontally (i.e., side by side) requires some additional handling, especially when dealing with multiline strings. In this article, we will explore different approaches for performing horizontal concatenation of multiline strings in Python. Method 1:Using the + Operator The + operator can be used to combine two or more strings into a single string. However, when dealing with multiline strings, using the + operator may ... Read More
RCU is a method that can manage multiple process execution and can be deployed to any operating system and one among them is the Linux kernel. It is an easy process synchronization method and it splits the RCU update into two phases namely removal and reclamation. This mechanism allows the reads along with the updates to occur simultaneously. The process occurs concurrently between the many readers and updaters of the operating system. Apart from the easy process, it is also reliable to access for the simultaneous process. Read-Copy Update Definition Read-copy update (RCU) is one of the best data structures ... Read More
In data analysis and processing, it is necessary to group similar elements together for better organization and analysis of data. Python provides several methods to group elements into a matrix efficiently, using matrices. In this article, we will explore different approaches to grouping similar elements into a matrix using Python. Method 1:Using Numpy NumPy is a widely−used Python library for scientific computing, particularly for working with arrays. It provides powerful functions to create and manipulate matrices efficiently. If the elements are numeric, we can use the NumPy library to group them into a matrix efficiently. Example In the below example, ... Read More
In Python, we can group sublists by another list using various methods like using a dictionary and using the itertools.groupby() function, using a nested list comprehension. Grouping sublists by another list can be useful when analyzing large datasets and categorization of data. It is also used in text analysis and Natural language processing. In this article, we will explore different methods to group sublists by another list in Python and understand their implementations. Method 1:Using a Dictionary A dictionary can be used in a very straightforward manner to group sublists by another list in Python. Let’s understand the usage of ... Read More
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
In Python, we can group words with similar stat and end characters using methods like dictionaries and loops, utilizing regular expressions, and implementing list comprehensions.The task involves analyzing a collection of words and identifying groups of words that share common starting and ending characters. This can be a useful technique in various natural language processing applications, such as text classification, information retrieval, and spell−checking. In this article, we will explore these methods to group similar start and end character words in Python. Method 1:Using Dictionaries and loops This method utilizes a dictionary to group words based on their similar start ... Read More
