digital+terms

=In the digital world, they are alot of complex terms. but people dont know what are these. Here are some examples:=

Digital logic is the basics for digital computing. It is fundamental to understanding how circuits and hardware communicate in a computer. Digital logic is the representation of signals and sequences of a digital circuit through numbers. It is typically used in most electronic devices including calculators, computers, video games and watches.



• A logic gate is an elementary building block of a digital circuit. Most logic gates have two inputs and one output. At any given moment, every terminal is in one of the two binary conditions low (0) or high (1), represented by different voltage levels. There are seven basic logic gates: AND, OR, XOR, NOT, NAND, NOR, and XNOR



• A truth table is a breakdown of a logic function by listing all possible values the function can attain. Such a table typically contains several rows and columns, with the top row representing the logical variables and combinations, in increasing complexity leading up to the final function  • thefollowing rules apply: - If A = 0, then -A = 1

If A = 1, then -A = 0

A+B = 1 except when A = 0 and B = 0

A+B = 0 if A = 0 and B = 0

A*B = 0 except when A = 1 and B = 1

A*B = 1 if A = 1 and B = 1

• Integrated circuits are used for a variety of devices, including microprocessors, audio and video equipment, and automobiles. Integrated circuits are often classified by the number of transistors and other electronic components they contain: •SSI : Up to 100 electronic components per chip •MSI: From 100 to 3,000 electronic components per chip •LSI : From 3,000 to 100,000 electronic components per chip •VLSI: From 100,000 to 1,000,000 electronic components per chip •ULSI : More than 1 million electronic components per chip

•Is an a bbreviation for Light Emitting Diode, an electronic device that lights up when electricity is passed through it. LEDs are usually red. They are good for displaying images because they can be relatively small, and they do not burn out. However, they require more power than LCDs.

• A breadboard is used to build and test circuits quickly before finalizing any circuit design. The breadboard has many holes into which circuit components like ICs and resistors can be inserted. • The bread board has strips of metal which run underneath the board and connect the holes on the top of the board. The metal strips are laid out as shown below. Note that the top and bottom rows of holes are connected horizontally while the remaining holes are connected vertically. A breadboard is a rectangular plastic box filled with holes in which you can insert electronic components and wires. A breadboard is what you use to string together a temporary version of your circuit. You don't have to solder wires or anything else; instead, you insert your components and wires into the holes.
