It allows for constant reconfiguration of devices and programs to meet changing needs and user behavior while remaining efficient. Network agility is an approach to computer networking that focuses […]
Network agility is a flexible and adaptable approach to computer networking that uses automation and standardized systems to maintain stability and usability. It allows for constant reconfiguration of devices and programs, and can grow to meet changing business needs. Users’ behavior and protocols are also important for short-term stability and long-term performance. Network agility is […]
A back-propagation neural network is an artificial neural network that uses back-propagation to learn by example. It can solve complex problems and adapt its structure based on information received. The concept was refined over the years and recognized as a breakthrough in 1974. In the world of programming, computers, and artificial intelligence, a back-propagation neural […]
A network architect designs, installs, and evaluates data communication systems like LANs, WANs, and intranets. They select and install hardware and software, and may also install telecommunications solutions. Network architects often work in IT services, telecommunications, and financial services. They need a degree in computer science or information technology and several years of experience. They […]
A project network diagram shows the time relationships and dependencies of steps in a project. It can be created in various ways, including the precedence diagram method (PDM). The diagram allows for the calculation of start and finish dates, resource allocation, and analysis of scheduling decisions. It also calculates ES, EF, LS, LF, and the […]
Various network management models, including TNM, CMIP, and SNMP, are used to organize and supervise computer networks. These models focus on the five functional areas of FCAPS: fault, configuration, accounting, performance, and security management. TNM is organized into four management levels, while CMIP is complex and CMIS is easier to use. SNMP is primarily used […]
Network simulation is a virtual representation of a network used to identify problems in existing networks or before building new ones. It saves money by improving network reliability, reducing maintenance costs, and increasing productivity. A network simulation is a virtual representation of a network. There are two common types of network simulation: one is used […]
Adaptive neural networks process information and make changes to the network when needed. They are used in computer systems and organic life forms. Man-made adaptive neural networks are modeled after natural neural networks. They learn through supervised or unsupervised learning and can perform tasks such as clustering, pattern recognition, function estimation, and prediction. They are […]
A network access server provides remote access to various resources, including the internet, printers, and telecommunications systems. Users are authenticated with login credentials and a password. A NAS can connect to an ISP, join different computer networks, and provide telephony services. It is commonly used by companies with remote workers and is governed by standardized […]
A wireless network diagram visually displays how devices connect and communicate in a wireless network. It can be represented through a flowchart or lines connecting devices. The diagram shows all devices and their connections, and can use different shapes or images to indicate device types. The direction of lines can indicate data transmission direction. A […]
Network delay is the time it takes for a packet to travel from one device to another in a packet switched network. In a circuit switched network, it only includes travel time. Network delay includes transmission, propagation, processing, and queue delays. Excessive delay can cause packet jitter and loss, resulting in garbled phone calls and […]
A computer network is a collection of devices connected for resource sharing. A network diagram shows the physical layout, protocols, and ports used. Network devices like switches and routers are included. Monitoring tools track device failures, and automation tools simplify diagram creation. A computer network is a collection of computing devices connected by communication devices […]
A network management suite is software that manages networks by bundling multiple types of software together to perform tasks such as detecting and alerting problems, measuring performance, managing security, and configuring components. It helps organizations ensure their networks run smoothly and protect confidential information. A network management suite is a type of software that allows […]
Network topology refers to how a computer network is organized, with physical and logical topologies. Physical topology types include bus, ring, star, and mesh, each with advantages and disadvantages. When choosing a topology, consider budget, network layout, and maintenance requirements. For home networks, choose a simple and easy-to-maintain topology, while for enterprises, choose a reliable […]
A network card driver controls a network card and manages one or more network adapters for a specific OS. Older drivers handled more tasks, but newer ones are easier to write and maintain. Multiple drivers can run simultaneously, and manufacturers often publish updates online. A network card driver is low-level software that controls a network […]
Network consultants assist businesses in designing, implementing, and maintaining computer networks. They may build a network from scratch or update an existing one. Consultants need knowledge of telephony, computer equipment, and programming. They may work independently or with a firm and can have broad or limited responsibilities depending on the client’s needs. Network consultants are […]
A network monitor is software that analyzes network activity, often managed by the network or system administrator. It helps prevent unauthorized access to data, locates network problems, and improves bandwidth. It can also analyze internet traffic but may be frowned upon. As technology advances, monitoring software evolves, and the role of the human administrator changes. […]
Network architecture refers to the planning, placement, and physical parts of a networked system. It can include usage and billing information and is used by service providers to locate bottlenecks and determine usage rates. The term has evolved from a basic layout to a blueprint and now refers to both the plan and physical network […]
