There are two popular types of architectures based on the instruction set. They are CISC (complex instruction set computing) and RISC (Reduced Instruction set computing). Let us discuss the underlying differences, advantages, disadvantages and similarities between these two architectures. What Is RISC (Reduced Instruction Set Computing)? RISC (reduced instruction set computer) is a computer that … Read more
PHP (Hypertext Preprocessor) is a general-purpose server scripting language and a powerful tool for making dynamic and interactive web pages. PHP is widely used, free and efficient alternative to competitors such as Microsoft’s ASP. PHP was originally created by Rasmus Lerdorf in 1994 and is now produced by the PHP group.

Polymorphism means ability to take more than one form. Polymorphism is considered as one of the important features of Object Oriented Programming. In C++ polymorphism is mainly categorized into two types, Compile time polymorphism (Static) or (Dynamic) Runtime polymorphism. In dynamic polymorphism, the response to a function is determined at the run-time whereas in static … Read more
What Is A Travelling Wave Tube? A travelling wave tube (TWT) is a specialized vacuum tube that is used in electronics to amplify radio frequency (RF) signals in the microwave range. The TWT belongs to a category of ‘’linear beam’’ tubes, such as the Klystron, in which the radio wave is amplified by absorbing power … Read more
PAN( Personal Area Network) PAN stands for Personal Area Network. It is sometimes referred to as Wireless personal Area Network (WPAN). It’s a network covering a very small area, typically a small room. It enables computer devices to communicate with other nearby computers and exchange information and data. Devices in one PAN network can establish … Read more
An image function f(x,y) must be digitized both spatially and in amplitude in order to become suitable for digital processing. Typically, a frame grabber or digitizer is used to sample and quantize the analogue video signal. Therefore, in order to create an image which is digital, we need to convert continuous data into digital form. … Read more
Virtual Memory Virtual memory is a memory management capability of an operating system (OS) that uses hardware and software to allow a computer to compensate for physical memory shortages by temporarily transferring data from random access memory (RAM) to disk storage. In other words, it is the separation of logical memory from physical memory. This … Read more
Bluetooth is a wireless connection standard that allows for exchange of data over short distances. It’s named after the 10th century Danish King Harald Bluetooth, who united Denmark’s tribes into a single kingdom. A new version of Bluetooth standard means various improvements, but only when used with compatible peripherals. Before Bluetooth version 4.2 in 2014, … Read more
The polarity of the electric current created by the welding machine, which runs through the electrode, is either AC or DC. These are the two types of polarity and the welding quality and efficiency depend significantly on the type of current used. AC Welding AC stands for Alternating Current. In an AC electric circuit, the … Read more
In conventional computers, translation of the program or the source code into object/machine code is done by various methods which include assembler, compiler and interpreter. Below are the underlying details of how they differ from one another. What You Need To Know About Assembler An assembler is a program that takes basic computer instruction or … Read more
