A control unit whose binary control values are saved as words in memory is called a microprogrammed control unit.A controller results in the instructions to be implemented by constructing a definite collection of signals at each system clock beat. Each of these output signals generates one micro-operation including register transfer. Thus, the sets of control signals are generated definite micro-operations that can be saved in the memory.Each bit that forms the microinstruction is linked to one control signal. When the bit is set, the control signal is active. When it is cleared the control signal turns inactive. These microinstructions in ... Read More
Electric circuits are classified into two main types namely series circuit and parallel circuit based on the arrangement of components in the circuit. A series circuit is one in which the components are chain connected, while a parallel circuit is one in which all the circuit components are connected between two common points. Series circuits and parallel circuits act as voltage divider circuits and current divider circuits, respectively. Read through this article to find out more about Current Division Rule and Voltage Division Rule. Current Division Rule A parallel circuit acts as a current divider as it divides the total ...

Data mining functionalities are used to represent the type of patterns that have to be discovered in data mining tasks. In general, data mining tasks can be classified into two types including descriptive and predictive. Descriptive mining tasks define the common features of the data in the database and the predictive mining tasks act inference on the current information to develop predictions.There are various data mining functionalities which are as follows −Data characterization − It is a summarization of the general characteristics of an object class of data. The data corresponding to the user-specified class is generally collected by a ... Read More
A set of flip-flops forms a register. A register is a unique high-speed storage area in the CPU. They include combinational circuits that implement data processing. The information is always defined in a register before processing. The registers speed up the implementation of programs.Registers implement two important functions in the CPU operation are as follows −It can support a temporary storage location for data. This supports the directly implementing programs to have fast access to the data if required.It can save the status of the CPU and data about the directly implementing program.Example − Address of the next program instruction, ...

We use the appearance property to style an element according to the platform-native style of the user’s operating system. The custom checkbox looks different from the default checkbox, and after selecting it the appearance will change. Syntax The syntax of CSS appearance property is as follows − Selector { appearance: /*value*/; -webkit-appearance: /*value*/; /*for Safari and Chrome */ -moz-appearance: /*value*/; /*for Firefox */ } Create a Round Custom Checkbox To create a round custom checkbox, we have set the following style with border-radius and box-shadow. The appearance is set ... Read More
When working with a large array of cells, manually cross-checking if a specific cell value is repeated in another column in the spreadsheet can be difficult and lead to skewed results. Fortunately, there are several options in Microsoft Excel that allow you to do this quickly and efficiently. In a few simple steps in this tutorial, we demonstrate how to use the Excel functions like VLOOKUP and MATCH to cheack if a value from one column exists in any other column in a worksheet. Method 1 Finding If Value Exists In Another Column Using VLOOKUP Function As shown in the ... Read More
Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a network protocol for carrier transmission that operates in the Medium Access Control (MAC) layer. It senses or listens whether the shared channel for transmission is busy or not, and defers transmissions until the channel is free. The collision detection technology detects collisions by sensing transmissions from other stations. On detection of a collision, the station stops transmitting, sends a jam signal, and then waits for a random time interval before retransmission.AlgorithmsThe algorithm of CSMA/CD is:When a frame is ready, the transmitting station checks whether the channel is idle or busy.If ...

A rectifier is an electronic circuit that converts the alternating current (AC) into direct current (DC). The process of conversion of alternating current into direct current is known as rectification. The rectifier consists of semiconductor diodes to perform the rectification.Depending upon the type of conversion of AC into DC, i.e., half cycle of AC into DC or full cycle of AC into DC, the rectifiers are classified into two categories viz. −Half Wave RectifierFull Wave RectifierIn this article, we will discuss about the differences between half-wave rectifier and full-wave rectifier. Also, we will briefly discuss about the half-wave rectifier and ... Read More

A program consisting of the memory unit of the computer includes a series of instructions. The program is implemented on the computer by going through a cycle for each instruction.In the basic computer, each instruction cycle includes the following procedures −It can fetch instruction from memory.It is used to decode the instruction.It can read the effective address from memory if the instruction has an indirect address.It can execute the instruction.After the following four procedures are done, the control switches back to the first step and repeats the similar process for the next instruction. Therefore, the cycle continues until a Halt ... Read More
