Standing Wave Ratio (SWR) meters are used to measure the standing wave ratio in a communications transmission line. The meter can display how much a transmission line and the load are mismatched (normally a radio antenna). It also determines how effective the impedance is of matching efforts. In CB and ham radio circles, the SWR …
The term stereoscopic vision refers to the human ability to view with both eyes in similar, but slightly different ways. This allows humans to judge distance, which develops their ability to have true depth perception. Historically, the human’s ability to view the world through stereoscopic sight has given him/her a significant advantage over entities and …
The term Inter-Process Communication (IPC) refers to a predefined library or set of interfaces that allow processes to communicate with each other. IPC gives the appearance of programs that run concurrently in an operating system’s background and allows computer users to conduct multiple tasks at once on a computer. IPCs can share memory, run in …
The Waterfall model is one of the best known applications of the Systems Development Life Cycle model (or SDLC), commonly used in the information systems, software, and systems engineering fields. The model is a sequential design process and gets its name from the visual depiction of progress, following the methodology looking like a waterfall as …
ZigBee is a wireless protocol that was developed as an International standard to enable wireless, machine to machine communication, and networks. It is considered the catalyst for constructing “Smart” enabled buildings and homes since it is based on reliable network communications, a pro-longed battery life, and can be simply operated. The ZigBee Alliance is the …
SYSVOL is the acronym for the SYSFOL folder and all of the files stored in it on the Windows Operating System (OS). It stores the server’s copy of public data and files for the domain. These files consist of group or user policy information. The information stored in the SYSVOL folder is copied to all …
Subatomic particles are the most elementary particles found in nature. The three basic subatomic particles that comprise an atom are protons, electrons, and neutrons. The historical definition of a subatomic particle was expanded over the past several decades to include elementary particles that are less complex than an atom and cannot be broken down further. …
Eddy currents are also referred to as Foucault currents and are created when conductors are exposed to a changing magnetic field because of a field source’s relative motion. Their applications include induction heating and non-destructive testing. Eddy currents are continually researched in order to develop new applications. How do Eddy Currents Work? Eddy currents are …
The Microsoft Corporation in conjunction with Windows Vista Service Pack 1 (SP1) released the exFAT file system. The exFAT file system was produced in order to address the short comings of the FAT32 file system; specifically on portable media such as USB sticks or portable hard drives where NTFS file structure use is inappropriate. The …
Zeroconf (zero configuration networking) refers to several protocols and techniques that are used together to create an IP (Internet Protocol) network with no special configuration servers or manual operator intervention. These networks allow novices to connect computers, network devices, scanners, and printers to create a functioning network without requiring manual configuration. Zeroconf does not require …
