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

Memory allocation can be described as a process of assigning the physical or the virtual memory address space to a program (its instructions and data). The two basic methods of memory allocation are: Static Memory Allocation Dynamic Memory Allocation What Is Static Memory Allocation? Static memory allocation is the allocation of memory at compile time, … Read more

What Is Single Precision? Single precision is a format proposed by IEEE for representation of floating-point number. It occupies 32 bits in a computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. A floating-point variable can represent a wider range of numbers than a fixed-point variable of … Read more

What Is An Adder? An adder is a digital circuit that performs addition of numbers. In many computers and other kinds of processors adders are used in the arithmetic logic units or ALU. They are also used in other parts of the processor, where they are used to calculate addresses, table indices, increment and decrement … Read more

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. There are different types of circuit breakers made in varying sizes, from small devices that … Read more

Volt and ampere are two measures of electrical current or flow of electrons. They define characteristics of an electricity supply. Voltage is a measure of the pressure that allows electrons to flow while ampere is a measure of the volume of electrons. These measurements of supply allow us to calculate the power a supply can … Read more

What Are P And NP Problem? Computer algorithms take a certain amount of time to solve the problem they are tasked with. Generally, you can roughly estimate how much time an algorithm will take using the number of elements they need to handle. Computer scientists call the number of elements N. Because some algorithms are more … Read more
