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 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

What is a Key in DBMS? Key in DBMS is an attribute or set of attributes which helps you to identify a row(tuple) in a relation(table). They allow you to find the relation between two tables. Keys help you uniquely identify a row in a table by a combination of one or more columns in that … Read more
Electromagnetic radiation is transmitted in waves or particles at different wavelengths and frequencies. This broad range of wavelengths is known as the electromagnetic spectrum EM spectrum). The spectrum is generally divided into seven regions in order of decreasing wavelength and increasing energy and frequency. The common designations are radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), … Read more
Statement This JDBC API interface is used for static SQL statements at run time. There is no specific protocol in statement interface. The statement interface does not allow accepting parameters at runtime. This interface is used when the SQL query is required to be executed only once. The performance of the statement interface is comparatively … Read more
