What is Current? In electric circuits, current is the flow of electric charge. It’s really electrons (charged particles) that move around in circuits. Electric current are the electrons or negatively charged particles that move around in circuits. So when current flows in some direction in a circuit, the actual physical effect is electrons flowing in the opposite … Read more
What Is Latitude? Latitude is a geographical coordinate that specifies the north-south position of a point on the Earth’s surface. The latitude has the symbol of phi, (φ) and it shows the angle between the straight line in the certain point and the equatorial plane.

There are two types of circuit namely combinational circuit ( no memory elements to store past or future values which may affect the output ,only present input changes the output ) and sequential circuit ( memory element like flip-flop are involves which store data and changes the output ). Latches and flip-flops are the basic … Read more
What is a Desktop? A desktop computer is a personal computer designed for regular use at a single location on or near a desk due to its size and power requirements. The most common configuration has a case that houses the power supply, motherboard (a printed circuit board with a microprocessor as the central processing unit, memory, bus, certain peripherals and other electronic components), disk storage (usually one or more hard disk drives, solid state drives, optical disc drives, and … Read more

What is a Satellite Phone? A satellite phone, also known as a satphone, is a type of mobile phone that communicates through satellites rather than traditional terrestrial cell towers. … Read more
What Is Pushdown Automata? A pushdown Automata is essentially a finite automaton with an auxiliary data structure (extra memory) known as a stack, which helps Pushdown automata to recognize Context Free Languages. Pushdown automata are used in theories about what can be computed by machines. They are more capable than finite-state machines but less capable … Read more
