What Is Network Architecture? A Guide For Your Next-Gen Enterprise Network
Network architecture is the design of a computer network. It is a framework that specifies the structure, physical components, functional organization, operational procedures, software, and data formats for constructing and managing a computer network. Network architecture can be used to provide a detailed picture of the communication, network protocols, and infrastructure used in the network. It includes hardware, transmission media, and network protocols that function together to provide network services to users. Types of network architecture include Local Area Networks (LANs), Wide Area Networks (WANs), and Metropolitan Area Networks (MANs).
What Are RADIUS Servers, and How Does RADIUS Authentication Work?
RADIUS (Remote Authentication Dial-In User Service) is a client-server protocol and software that enables remote access servers to communicate with a central server to authenticate dial-in users and authorize their access to the requested system or service. Internet Service Providers (ISPs) and enterprises widely employ RADIUS for overseeing access to the internet or internal networks, encompassing wireless networks and integrated email services. It accomplishes this by utilizing a RADIUS server, which holds (or is able to access) user credential information and the rules that determine which users can access which networks or services.
What Is a Wireless Sensor Network? How Does It Work?
A wireless sensor network is a group of autonomous sensors dispersed in space, observing physical conditions like temperature, sound, and pressure. Some are also capable of testing the performance of the wireless network infrastructure that they are connected to. These sensors cooperatively transmit data to a central location using embedded processors, radio transceivers, and batteries when not connected to power. Wireless sensors serve various purposes, including network connectivity performance analysis, system health monitoring, wildlife tracking, agriculture, industry, and military. Initially driven by military use like battlefield surveillance, they're now integral to civilian applications such as habitat monitoring, healthcare, home automation, and traffic control.
What Is Network Design? And How To Design A Network
Network design entails strategizing and establishing computer network infrastructures. It includes optimizing devices, services, and technologies to suit individual or organizational requirements. This can include deciding upon a network's architecture or topology, choosing the appropriate hardware and software, planning for data storage and management, considering the requirements for an internet connection, and ensuring the necessary security measures are in place.
