Unshielded Twisted Pair (UTP) Cables In UTP cable, conductors which form a single circuit are twisted around each other in order to cancel out electromagnetic interference (EMI) from external sources. Unshielded means no additional shielding like meshes or aluminum foil which add bulk is used. UTP cables are often groups of twisted pairs grouped with … Read more
What Is Kerberos? Kerberos is a computer-network authentication protocol that works on the basis of tickets to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. It uses secrete-key cryptography and a trusted third party for authenticating client-server applications and verifying user’s identities. Users, machines and … Read more
What is Co-channel Interference? Co-channel interference (CCI) occurs in wireless communication systems, particularly in scenarios where multiple transmitters use the same frequency channel to communicate simultaneously. When this happens, the signals from different transmitters interfere with each other, degrading the overall quality of communication. In simpler terms, imagine several people talking at the same time … Read more
What Is An Inline Function? The inline functions are a C++enhancement feature to increase the execution time of a program. In an inline function, a function call is directly replaced by an actual program code. It does not jump to any block because all the operations are performed inside the inline function. Compiler replaces the … Read more
Static RAM and Dynamic RAM are both types of Random Access Memory (RAM). A random access memory is a random-access memory device that allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory. RAM is typically used to store working … Read more
What Is Modulation? Modulation is the process of encoding information from a massage source in a way that is suitable for transmission. This is achieved by altering the characteristics of a wave. By superimposing a message on to a high frequency signal referred to as carrier wave (or sinusoidal signal), video, voice and other data … Read more
Linker A linker is a computer program that takes one or more objects generated by a compiler or an assembler and combines them into a single executable program. Computer programs are usually made up of multiple modules that can separate object files, each being a compiled computer program. The program as a whole refers to … Read more
LED (Light Emitting Diode) A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. Early LEDs produced only red light, but modern LEDs can produce several different colors including red, green and blue … Read more
What Are Combinational Circuit (CC)? Combinational circuits are circuits made up of inputs, outputs and two or more logic gates. A logic gate is a basic building block of any electronic circuit. The circuits have no memory, timing or feedback loops, there operation is instantaneous. A combination logic circuit performs an operation assigned logically by … Read more
What Is Fork ( )? Fork is a function in UNIX operating system that is used to generate a duplicate of particular process by creating two simultaneous executing processes of a program. These two processes are typically called the ‘’parent’’ and ‘’child’’ processes. They use multitasking protocols to share system resources. When fork creates a … Read more
