Metadata is a term that refers to the data that is collected, organized, and stored data in order that the data may be categorized and used in relevant ways for further research by other users. In fact, metadata is often quite simply defined as being “data about data”. Metadata is often referred to as descriptive […]
An ion is a molecule or an atom that is charged and the electrons do not equal the number of protons in the atom or molecule. It was introduced by one of the most influential scientists Michael Faraday during 1834. Although Faraday did not know where these species came from, he described the portions of molecules in a […]
Virtual desktop infrastructure (VDI) refers to all resources, including hardware and software required by a user to access a virtual desktop stored in a remote server through the internet. It involves holding a desktop OS in a virtual machine that runs on a central server. VDI’s model varies from the server or client computing model […]
Watt is a basic unit of all types of power like electrical power, mechanical power or thermal power. Watt is named after the scientist James Watt, who invented Steam engine. He is a Scottish scientist lived in the period of 1736- 1819. He improved steam engine and contributed greatly to the usage of steam power […]
Analog also typed Analogue, explains a tool or system that is changing values as consistently varying physical amounts. A normal analog device is a clock where the hands transfer constantly round the face. This kind of clock is capable of doing shows every single possible time. Conversely, a digital clock is capable of doing representing […]
Diode is Probably the most typical ways to use the diode is to transform alternating electric current (AC) into direct current (DC). Every diode is consists of a cathode plus an anode, which each connects on the outside. When Alternating current is being applied, electricity goes through the diode. In cases like this, a positive […]
Digital is an electric technology that creates, stores, and operations data and information with regard to two states: positive and non-positive. Positive is indicated or displayed by the number one and non-positive with the number zero. Therefore, data carried or saved with digital technology which is indicated as a string of Zeros and ones. Each […]
OSI stands for Open System Interconnection, the OSI model defines the networking framework to put into action the protocols in seven different layers. The control is passed on from one layer to the next from the application layer down to the physical layer and works its way back up the hierarchy on the other end. […]
Wavelength Division Multiplexing (WDM)
Before discussing Wavelength Division Multiplexing, let discuss wavelength. Wavelength is the distance that is between two repeating units of a particular wave given that it is measured from one point to another corresponding point. For instance, the distance of the top part of a wave, known as the crest, to the other crest is considered […]
