In the OSI (Open Source Interconnection) model, the resource reservation model comes under the fourth layer which is the transport layer protocol. This protocol is particularly used for the purpose of reserving network resources. In RSVP, the resources are associated and maintained by the receiver so it is also known ... Read More

Deadlock in an operating system happens when a process gets into a waiting state as other processes hold the resources which need to be used. This problem generally happens during multi-processing environments, distributes systems, and parallel computation systems. In distributed systems, deadlocks are considered the major problem, where the resources ... Read More

A routine is said to be a computer program with a set of instructions that is used for the execution of the system program. They allocate or deallocate the memory used after completion of its execution as per instructions given as routine-routine or even functions. The process is termed as ... 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 ... Read More

Introduction Each file stored in computer memory has specific information that is given by the user. The files stored in the file system can be in various forms like image, audio, video, text etc. All these forms of data have different format extensions. Operating system is responsible for managing the ... Read More

MediaFire helps the user with a storage feature that enables them to access the data from anywhere without any difficulty. In both cases, the files or folders can be uploaded remotely and provides free storage space without any prior subscription. High−resolution pictures and videos are kept safe and secured in ...

In digital communication, Delta Modulation and Differential Pulse Code Modulation are the techniques with fixed step size and it has updated ones with varying step size as Adaptive DM and DPCM. The Correlation between the current sample and a predicted value is quantized for both approaches to function. The main ... Read More

In the recent era of digital technology, people connected to the network need to send data within a minimum time and aim to save storage space for media files. When large files have to be transmitted simultaneously in a shorter period, then the user can choose any compression method to ... Read More

Open System Interconnection (OSI) model consists of seven major layers. The layer−2 of the OSI stack and the switches working in this layer is layer−2 switch. Similarly, the third layer of this model is called the network layer and the switches working in this layer is layer−3 switch. Initially, Local ... Read More

In this article, we will understand the concept of Kerberos and Radius and the difference between them. The three main components of Kerberos are the computer that contains the database, the ticket−granting server, and the authentication server. RADIUS does not store data in a specific format but rather talks with ... Read More
