Systems engineering (SE)

Systems engineering (SE) is an interdisciplinary field of engineering and engineering management that focuses on how to design and manage complex systems over their life cycles. Systems engineering deals with the design, integration, and operation of complex systems. It is a holistic approach that considers the system as a whole, rather than as a collection … Read more

Cache server

A cache server is a type of network hardware that is designed to improve the performance of a network by storing frequently requested data in a local cache. By storing this data locally, the cache server can provide faster access to the data than if it were retrieved from a remote location. Cache servers are … Read more


Buckypaper is a thin sheet of carbon nanotubes (CNTs) that can be used as a material for various applications. The name “buckypaper” comes from the fact that the material was first made from buckminsterfullerene (C60), a type of carbon molecule. Buckypaper is strong and lightweight, and can be used as a conductor of electricity and … Read more

Network access point (NAP)

A network access point (NAP) is a connecting point for devices in a network, typically a local area network (LAN). A NAP provides a central location for users to connect to the network and allows for the easy expansion of the network as more users are added. A NAP is typically a hardware device, such … Read more

Server refresh cycle

The server refresh cycle is the process of refreshing or replacing the hardware in a server. This can be done for a number of reasons, such as to improve performance, to add new features, or to address hardware defects. How Often Should servers be replaced? There is no definitive answer to this question as it … Read more

T interface

A T interface is a type of network hardware that is used to connect two network devices together. The T interface is a physical interface that uses a T connector to connect the two devices. The T interface is a unidirectional interface that allows data to be transferred between the two devices in only one … Read more

Hard reset (factory reset; master reset)

A hard reset is a factory reset that returns a device to its original, out-of-the-box state. This includes all personal data, settings, and applications. Hard resetting a device is often necessary when it is not responding to traditional reset methods. A hard reset should only be performed as a last resort, as it will delete … Read more

Edge node

An edge node is a type of network node that is located at the edge of a network. Edge nodes are typically used to connect devices to the network, and they typically provide access to the network for devices that are not connected to the network core. Edge nodes typically have less processing power and … Read more
