A logical network is a model of the connection between entities in which each entity is defined by a node, and the links between nodes represent the connections. The goal of using this model is to understand how different parts of an organization are related to one another. In other words, it can be used to understand how tasks or resources are allocated within an organization based on its capacity (availability) and needs (priority). Logical networks also help us see patterns in our data that would not be evident when looking at individual pieces of information. The source and destination are connected by a network, which is made up of various elements and parts. Physical and logical components are the two categories used to represent the elements and parts of a network. Each element is represented by its own physical or logical component, with the exception of hosts which have no corresponding physical or logical part because they can not be mapped to another hosting type (components

A Wide Area Network (WAN) is a telecommunications network that extends over a large geographic area, such as a city, country, or even global regions. It is designed to connect multiple local area networks (LANs) and other networks, enabling communication and resource sharing between devices and systems that are geographically dispersed. Key Characteristics of WANs: Geographic Scope : WANs cover extensive areas, from several miles to continents, linking networks across cities, states, or countries. Transmission Media : WANs use various transmission technologies, including leased lines, fiber-optic cables, satellite links, and wireless communications, to connect different locations. Performance and Speed : WAN speeds can vary significantly depending on the technology used and the network design. High-speed connections are often implemented using fiber-optic cables, while satellite and older technologies may offer slower speeds. Network Devices : WANs utilize routers, switches, modems, an

  System testing is a collection of all software testing types since it encompasses all the primary testing types. Products, processes, deadlines, and needs all have a role in determining which types of testing are prioritized. Here are some types of system testing that play an essential role in the software testing process. 1. Functionality Testing To ensure that the product’s performance meets the required criteria while remaining within the constraints of the system, this phase evaluates whether the system, and notably its functionalities, abide by the objectives. Throughout functional testing, analysts might think of ways to improve a product by listing down prospective add-ons. The data supplied reflects both human and automated testing settings. 2. Recovery Testing By simulating various input mistakes and other failures, you can evaluate the method’s resilience to failure. You can also determine if it can recover from system shutdowns, hardware malfunctions, and other major diffi

  Artificial Intelligence (AI) and Machine Learning (ML) : AI and ML are transforming numerous fields by enabling systems to learn from data, make decisions, and perform tasks that typically require human intelligence. Applications range from natural language processing and image recognition to predictive analytics and autonomous vehicles. The focus is increasingly on improving algorithms, enhancing data privacy, and making AI more interpretable. Generative AI : This subset of AI involves creating new content—such as text, images, or even code—based on patterns learned from existing data. Generative AI tools like GPT-4 and image generators like DALL-E are advancing rapidly, opening up new possibilities in creative industries, content generation, and personalization. 5G and Beyond : 5G technology is expanding the capabilities of mobile networks, offering higher speeds, lower latency, and more reliable connections. This trend is crucial for the development of the Internet of Things (IoT)

  Network performance monitoring optimization is the process of maximizing the efficiency and reliability of data transmission across an organization’s network infrastructure.

  Network topology refers to the physical or logical layout of a computer network. There are several types of network topologies , each with its own advantages and disadvantages. Here are some common network topology types: Bus Topology : In a bus topology , all devices are connected to a single communication line (bus). Data travels along the bus, and each device receives the data intended for it. However, this topology can be susceptible to a single point of failure. Star Topology : In a star topology , all devices are connected to a central hub or switch. The central hub acts as a relay, allowing devices to communicate with each other through it. It provides better fault tolerance since the failure of a single connection typically doesn't disrupt the entire network. Ring Topology : In a ring topology , each device is connected to exactly two other devices, forming a circular loop. Data travels in one direction along the ring until it reaches its intended destination. The data tr

  Transmission Media: Transmission media is a medium that carries data from one device to another. It is a physical channel that helps to transmit data from transmitter to receiver. This physical channel can be wired or wireless, where data gets transferred in the form of electromagnetic signals. What are the characteristics of transmission media in Computer Networks: The following are some of the characteristics of transmission media-  Bandwidth : Bandwidth is the amount of data transmitted in a given time. Higher bandwidth implies a higher data transfer rate. Transmission Distance : It refers to the maximum distance data can travel. Different media have different transmission distances; hence it is a factor to be considered to prevent data loss. Interference : The presence of unwanted signals is known as interference. Different media have different levels of tolerance to unwanted signals. Cost : Cost also varies depending upon the type of media used. Transmission media types in Compu

  The Internet of Things (IoT) refers to a network of interconnected devices embedded with sensors, software, and other technologies that enable them to collect, exchange, and act on data through the internet. These devices range from household appliances to industrial machinery, all of which can communicate with each other and with users to enhance efficiency, convenience, and decision-making. Key Components Devices/Sensors: These are the physical objects embedded with sensors and actuators that gather data from their environment or perform specific functions. Examples include smart thermostats, wearable fitness trackers, and connected vehicles. Connectivity: The means through which data is transmitted between devices and systems. Common connectivity methods include Wi-Fi, Bluetooth, Zigbee, and cellular networks .

  Network switches are available in various types and categories to address different use cases. These are:  1. Managed switches Managed switches , most commonly seen in commercial and enterprise settings, provide greater capacity and capabilities for IT experts. To configure managed switches, command-line interfaces are utilized. They enable simple network management protocol agents, which offer information for troubleshooting network issues. Administrators can also use them to create virtual LANs to split a local network into smaller parts. Managed switches are substantially more expensive than unmanaged switches due to their additional functionality. 2. Unmanaged switches The most basic switches are unmanaged switches, which have a set configuration. An unmanaged switch merely expands a LAN’s Ethernet connections, allowing additional internet connections to local devices. Unmanaged switches use device MAC addresses to transmit data back and forth. They are usually plug-and-play, me
