Network virtualization is a method of separating networking resources from their physical hardware and re-creating them in software. The concept is simple: a system that mimics the functions of physical hardware such as switches, routers and load balancers. This virtual pool of hardware can be used for various purposes such as web hosting, file sharing and cloud storage. It is a scalable, stable and programmatically administered networking solution. When implemented correctly, network virtualization reduces costs and increases agility. By decoupling physical networks from network services, you can improve load balancing and security. You can also set location- and role-based permissions…

What is a computer network? Simply put, it is a set of computers connected by digital interconnections. The computers on a network share resources provided by network nodes. They communicate with each other using a common communication protocol. A network application allows computers to share resources and applications. The application works by sharing information between the computers on the same network. It is the perfect solution for businesses that need to share multiple applications and files. There are many types of network applications. Some of the most common are web applications, email, and instant messaging. All of these technologies can…

What is a network access point? This device is a wireless access point that connects to a wired local area network. It provides connections for multiple wireless devices. A router performs the same function but is more complex, supporting VoIP calls, IPTV, and password protection. A wireless-enabled access-point (WAP) adds Wi-Fi capability to a wired network. It may be a standalone device or a component of a router. An access point is a special hardware device that connects to a broadband router or network switch. This hardware device transmits and receives data, and connects users in a network. It acts…

Network-attached storage is a type of storage device that is connected to your router. This makes it accessible to all of the computers in your home network. It is convenient because you can access your files anywhere, including your mobile phone or tablet. You can even stream your home movies from the storage device. You don't even need to be at home to access them. Many NAS systems allow for unlimited data storage, so you can keep a copy of everything. The advantage of network-attached storage is that it is more affordable than storage area networks. The main disadvantage of…

Today's organizations rely on a network for basic connectivity, enhanced collaboration, and quality service. This makes the proper architecture and management of the network essential to the success of the organization. A network controller is a key member of the IT team who manages every aspect of a network so that it continues to run flawlessly and meet business objectives. There are many responsibilities of a network controller, but a few are more important than others. A network controller implements the electronic circuitry needed for communications in the physical and data link layers of a network. It facilitates communication between…

A network diagram is a representation of the relationships and dependencies between different components of a network. It can help you understand the growth and interconnection of systems and can be useful for sales pitches and high-level presentations of network changes. It is a very common tool for IT managers to use when planning the installation or upgrading of systems. However, if you don't have the skills to create a diagram yourself, you can hire someone to do it for you. The most common example of a network diagram is an information network. The connection between each device is made…

In the context of a network, the term "network externality" refers to the benefits or consequences of a system. The network is a collection of compatible systems that are either associated goods or durable goods. For example, the typewriter keyboard is a hardware product. Its capabilities are software, and the owners of a compatible typewriter system are a virtual network. The economics of network externality have been studied for decades. For example, network externality describes the effect of using a product or service on the value of others. When a product or service is used by many people, its value…

A network effect is when the value of a product or service increases as more users join the network. This is especially important when competition is fierce. More users means higher prices. If there is a network effect, then more users means more money. However, this type of network growth can lead to negative effects, including congestion and saturation. Here are some examples. In the first case, a platform might benefit if more users join, but it might not benefit if more users leave the platform. A network effect can be beneficial for a company with a differentiated inventory. If…

What is a network extender? A network extender is a device that boosts the signal of cellular networks in your home or on your property. Despite the name, this device is not related to the extended network feature of domestic roaming. However, similar devices are used to improve Wi-Fi signals. So, if your home or business is in an area where you struggle with poor reception, a wireless extender may be the solution. A network extender enables you to enjoy faster internet connections in areas where you don't have a signal. An Ethernet extender kit requires a wired connection. You…

A network is comprised of nodes and links. Flow refers to the amount of information that is transferred on a given link, regardless of the end nodes. In the context of the internet, the total amount of network flow is increasing slowly, but the size of the communications is increasing rapidly. The flow that we speak of is a subset of this. In this post, we will look at the main properties of a network and the types of flows that are possible in it. Network flows can be categorized into two kinds: unidirectional and bidirectional. The former is a…
