The Rapid Spanning Tree Protocol (RSTP) and the Per-VLAN Spanning Tree Protocol (PVST) are protocols used in Ethernet networks to prevent loops and provide network connection redundancy. RSTP is a Spanning Tree Protocol (STP) evolution that is designed to provide faster convergence times in response to changes in network topology. PVST is a Cisco proprietary protocol that creates a separate spanning tree for each VLAN using STP. Read this article to find out more about RSTP and PVST and how they are different from each other. What is RSTP? Rapid Spanning Tree Protocol (RSTP) is an evolution of Spanning ... Read More

FireWire and Thunderbolt are two types of high-speed data transmission interfaces used to connect various electronic devices to computers, such as cameras, hard drives, and other peripherals. Thunderbolt provides faster data transfer rates, power delivery, and a shorter cable length than FireWire, but it is more expensive and not as widely available. Read this article to find out more about Firewire and Thunderbolt and how they are different from each other. What is Firewire? FireWire uses a serial bus architecture, which means data is transmitted one bit at a time through a single cable. This allows for rapid and effective ... Read More

VLAN and VPN are two independent technologies in computer networking that serve different purposes. A virtual private network (VPN) is a secure, encrypted connection established through a public network (such as the Internet) to connect remote users or networks to a private network. A virtual local area network (VLAN) is a logical network formed within a physical network infrastructure. Read this article to find out more about VLAN and VPN and how they are different from each other. What is VLAN? A virtual local area network (VLAN) is a logical network formed within a physical network infrastructure. It allows ... Read More

The WHOIS command is a widely-used protocol for retrieving registration information about domain names and IP addresses. Originally intended for system administrators and network engineers to diagnose network issues, it has now become a popular tool for anyone looking to gather information on a domain or IP address. When you initiate a WHOIS query, your computer sends a request to a WHOIS server - a database of registered domain names and IP addresses. In response, the server provides registration information for the requested domain or IP address. The data obtained by the WHOIS command can include the name and contact ... Read More

In the realm of operating systems, process scheduling plays a vital role in achieving efficient task execution. A key aspect of process scheduling is the management of Process Control Blocks (PCBs) and the utilization of various queueing techniques. This article explores the significance of PCBs and queueing in the process scheduler, highlighting their role in optimizing system performance. Process Control Blocks (PCBs) Definition and Purpose The successful operation of an operating system rests on its ability to use the data structure known as a Process Control Block (PCB) effectively. PCBs allow for efficient storage and management of process related information. ... Read More

Multitasking underscores the versatility inherent in modern-day OSes that empowers computers with concurrent task handling capabilities. Process-based or thread-based multitasking represents efficient resource consumption strategies that positively impact overall system performance levels. While our article focuses primarily on examining process-oriented vs thread-oriented approaches' constituent elements thoroughly we hope to contextualize some finer nuances associated with each methodology's allocated uses cases within our discourse today concerning Operating Systems advancements widely adapted across contemporary environments worldwide at present times worldwide in digital life today. Process-Based Multitasking Definition and Purpose Process-based multitasking involves the execution of multiple processes concurrently. Each process operates independently ... Read More

Memory management is a critical aspect of computer systems that directly impacts their performance and stability. Within memory management, several terms come into play, including private bytes, virtual bytes, and working sets. In this article, we will embark on a comprehensive exploration of these fundamental concepts, unraveling their intricate meanings, contrasting characteristics, and utmost significance within the realm of memory management. When delving into the realm of comprehending memory usage, one must possess a profound acquaintance with an array of memory metrics. Private bytes, virtual bytes, and working sets emerge as quintessential gauges employed for meticulously scrutinizing memory consumption across ... Read More

Transmission Control Protocol comes under the fourth Layer of the Open System Interconnection model. The main purpose of TCP is to track the packets and these fields add extra information on the TCP header. The connection must be implemented before transferring the packets. Some of the errors that may arise while transferring packets are the packets may be lost, packets may replicate, and damaged. The Internet Protocol (IP) packet will follow a format called TCP segment which is composed of two parts namely the Header and data. In this article, the two fields of the TCP header namely MSS and ... Read More

Signaling system 7 is a protocol that comes under the network layer of the Open System Interconnection model. It helps the node of the network to track the transfers of messages. Message Transfer protocol is the basis and is divided into many layers according to its function. The first layer represents the setting up of the network, then the second layer take care of transmissions without any error and the third layer acts like a medium between two networks. MTP3B stands for Message Transfer Protocol broadband as it transfers multiple signals concurrently. What is MTP3? In the SS7 protocol, there ... Read More

MediaFire and Securesafe are storage devices used by different organizations and for personal purposes. MediaFire has been first launched in the year 2006 which provides a storage space of 10GB and later Securesafe was introduced in the year 2009 which provides 100 GB storage space. Using the Securesafe, it makes the user to access the data like pictures, videos and music very easily and securely. On the other hand, Mediafire does not provide any kind of security to the files stored. What is Mediafire? MediaFire provides a storage service in cloud-based and not physical. It saves and shares items including ... Read More
