Pipelining computer

Pipelining is the process of accumulating instruction from the processor through a pipeline. It allows storing and executing instructions in an orderly process. It is also known as pipeline processing. Pipelining is a technique where multiple instructions are overlapped during execution.

Introduction to Data Structure

DS introduction. A data structure is a special way of organizing and storing data in a computer so that it can be used efficiently. Array, LinkedList, Stack, Queue, Tree, Graph etc are all data structures that stores the data in a special way so that we can access and use the data efficiently.

Linear Modulation

It is a modulation technique for which super- position theorem stands correct. The modulations for which the above theorem does not hold good are called non-linear modulations. Linear modulation is the direct frequency translation of the message spectrum. DSB modulation (Double sideband) is precisely that.

Angle Modulation

Angle modulation is a class of carrier modulation that is used in telecommunications transmission systems. The class comprises frequency modulation (FM) and phase modulation (PM), and is based on altering the frequency or the phase, respectively, of a carrier signal to encode the message signal.

Digital Transmission of Analog Signals

To transmit analog message signals, such as voice and video signals, by digital means, the signal has to be converted to a digital signal. This process is known as the analog-to-digital conversion, or sometimes referred as digital pulse modulation.

Propositional Calculus

Propositional calculus is a branch of logic. It is also called propositional logic, statement logic, sentential calculus, sentential logic, or sometimes zeroth-order logic. It deals with propositions and argument flow. Compound propositions are formed by connecting propositions by logical connectives.

Analyzing Algorithms

Algorithm analysis is an important part of computational complexity theory, which provides theoretical estimation for the required resources of an algorithm to solve a specific computational problem. Most algorithms are designed to work with inputs of arbitrary length.

Computer Graphics-Video display devices

Here we learn about some of the concepts of Computer Graphics : Video display devices Cathode Ray Tube (CRT) Horizontal deflection and vertical deflection direct the electron beam to any point on the screen Intensity knob: regulates the flow of electrons by controlling the voltage at the control grid (high voltage reduces the electron density and thus brightness) Accelerating voltage from positive coating inside screen (anode screen) or an accelerating anode Image maintenance

Computer graphics-Refresh buffer or frame buffer

Here we learn about some of the concepts of Computer Graphics : *Raster Scan Displays *Refresh buffer or frame buffer: This memory area holds the set of intensity values for all the screen points. Stored intensity values then retrieved from refresh buffer and “painted” on the screen one row (scan line) at a time *Random Scan Displays Random scan displays have higher resolution than raster systems. Vector displays product smooth line drawing. A raster system produces jagged lines that are plotted as discrete points sets.
