Numerical Control (NC) Machine Numerical control, commonly referred to as NC, is a machine which is controlled by the set of instructions in the form of numbers, letters and symbols. In this case, the set of instruction is referred to as program. NC is essential to the operation of modern industrial robots. The two basic … Read more

Spreadsheet A spreadsheet is a computer application for organization, analysis and storage of data in tabular form. The program operates on data entered in cells of a table.

What Are Lists In Python? A list is a data structure in Python that is a mutable or changeable, ordered sequence of elements. Each element or value that is inside a list is called an item.  Lists are mutable. This means that you can modify a list after it has been initialized i.e you can … Read more

A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight. That is, it is a spanning tree whose sum of edge weights is less than or equal to the weight of every other spanning tree. More … Read more

Sum of Product (SOP) Sum of Product abbreviated as SOP is a form of expression in Boolean algebra in which different product terms of inputs are being summed together. This product is not arithmetically multiply but it is Boolean logical AND and the Sum is Boolean logical OR. Minterm is product of Boolean variable either … Read more

What Is Amplitude Modulation (AM)? The first amplitude modulated signal was transmitted in 1901 by a Canadian engineer by the name Reginald Fessenden. He used a continuous spark transmission and placed a carbon microphone in the antenna lead. This transmission was very crude; signals were audible over a distance of a few hundred meters. The … Read more

PCM (Pulse-Code Modulation) Pulse code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals and each sample … Read more

Handoff A handoff refers to the process of transferring an active call or data session from one cell in a cellular network to another or from one channel in a cell to another. A well-implemented handoff is important for delivering uninterrupted service to a caller or data session user. Cellular networks are composed of cells, … Read more

A database server is the key to solving the problems of information management. In general, a server must reliably manage a large amount of data in a multi-user environment so that many users can concurrently access the same data. All this must be accomplished while delivering high performance. A database server must also prevent unauthorized … Read more

Bitmap Graphics The bitmap also referred to as raster graphics can be described as a raster image containing pixel data format. Each pixel is actually a very small square that is assigned a color and then arranged in a pattern to form the image.  A bitmap image is a grid made of rows and columns … Read more
