A memory card reader is a device that acts as a connection between a flash memory stick or SD memory card and the computer. In other words, it is a memory hub that makes it possible to connect multiple memory cards to the computer at one time. Once the memory card is attached to the reader and the computer, the user can easily transfer files to and from the reader. Another reason that a memory card reader is beneficial is because it offers different size memory slots. Since there are Read More

A mashup is anything that results from a combination of data from different sources. Mashups could be accessed and found across the World Wide Web. It is considered to be one of the new types of web content today – an indication of the Web 2.0 phenomenon. A mashup usually refers to the merging of two or more sets of content from different sources using a web application. A good example of a mashup site is the www.chicagocrime.org. This website is a result of the merging or “mashup” of Google Read More

Superfluidity is the phase in which a fluid exhibits frictionless flow. The fluid’s viscosity vanishes and the thermal conductivity becomes infinite during this phase. This is possible because some liquids overcome friction when interacting with surfaces when the fluid’s viscosity is zero. Zero viscosity makes it possible for a fluid to have a very unique motion, which is yet to be fully understood or exploited. Properties of Superfluids Superfluidity allows matter to be in a state where a two fluid model can exist. This means that mass can be transferred Read More

The CRT (Cathode Ray Tube), is the vital component in most computer monitors and televisions. It is responsible for the images that we see in monitors and television sets. How a CRT Works The main component of a CRT is the picture tube. The tube is wide at the front and narrows at the rear end. The shape at the rear end can be compared to a bottle neck. The rear end consists of a negative charged filament, which is known as cathode. The filament is enclosed in a vacuum Read More

Named after Emile Baudot, the inventor of the Baudot code for telegraphy, a baud is a unit that is synonymous to symbols per second. Therefore, if there was something with 15 Bd, that would mean that something had 15 symbols per second. Not to be confused with bits per second, the baud — which, when using the symbol, must follow the SI nomenclature with a capital first letter and a lowercase second letter — can be any of the many different kinds of symbols while a bit is only 0 Read More

A computer operating system, such as Linux or Microsoft Windows, is a piece of computer software that has various components. Technically, it is a collection of programs crucial to a computing device’s operation. A personal digital assistant, a Smartphone and other such handheld devices now all have their own operating systems, without which these devices will not run. In the basic personal or notebook computer, the operating system is mainly that set of programs that run and manage the operation of all components of the computer – the monitor or Read More

In order to keep track of their belongings, companies use asset management software and practices that aid in organization and lead to better productivity. Asset management is an underlying need that transcends all industries and used to require a team of professionals to monitor and keep track of everything that a particular company does and uses. Fortunately, these professionals can now be replaced with asset management software that can be used by any company, no matter what their budget is. This article will define what asset management software does and Read More

This modern world of high speed Internet and fast-paced business is dependent on one thing: data. Data comes in many forms and can be represented in many different ways but the bottom line is that data makes up everything and society must rely on data to function. When that is understood, it is then imperative to deliver data as fast as possible. Because so much data is constantly being updated, transferred, and manipulated, however, there are limits on how much data can be transferred at one time. There are also Read More

ESN (Electronic Serial Number) An Electronic Serial Number is a code created to identify mobile devices. An ESN is 32 bits long, and the distribution of information in those bits has changed as the standard has evolved. The first 8 bits originally represented the manufacturer code, leaving 24 bits for the manufacturer to assign codes to mobile devices. This system allowed for up to 256 manufacturers and up to 16,777,215 unique codes for each manufacturer’s mobile devices. To allow for more manufacturers, the manufacturer code was extended to 14 bits, Read More
