What do you mean by database application on the computer? The database application provides the database tools to manage the data in the model of relational database. The relational database model application includes the different types of option and applies some query processes on the record of the database file and their attributes values in the table database. The query is performed by the query processor on the record using the key attributes on the relational database model. Database application included the different types of parts that process the data into the database file, where the user mostly uses the relational database model to process the text data in the table format of database file which included the record, attributes and query processor to apply the commands on the record to process the values of the attributes on the records of the relational database file. The user get the solution of the output data using the database programming to get the values processed by t

Central processing unit (CPU)and its units input unit, storage unit, control unit and ALU

The CPU is a main part of the computer. It control all the peripheral device of the mother board.

The primary function of a CPU is to execute instruction or programs. Besides it also controls the operation of all other components, such as memory, input and output devices. Under the processing unit control, Programs and data are accepted from the input devices and stored in the memory. Outputs are displayed on the video screen or printed on paper once the processing of a program is complete.
The processing unit of a small computer normally has a single processor, Whereas the one for a bigger computer may contain a number of processors. Each processor, in a large processing unit, performs a specific task assigned to it.


CPU working


In this figure the solid lines are shows us to indicate the flow of data and also flow of the instruction.
 The dotted lines represents the control exercised by the control unit.
 The figure shows the basic arrangement of different units of a computer.


CPU: The figure shows the Central Processing unit is the combination of the Control unit and Arithmetic logic unit that are connected to each other permanent line as shown in the above figure.

Input Unit: The input unit works with Control Unit, Storage Unit and Arithmetic Logic Unit in the execution of the instructions.

Storage Unit: The storage unit stores the instruction of the input signal or instruction which is controlled by the control unit and calculated by the arithmetic and logic unit in the CPU processing system for making to prepare the output signals or the instructions.

Controls Unit: The control unit controls the instruction of the input signals are where that transfers the in the storage unit and also to set timing of the execution to execute to output signals or instructions.

Arithmetic Logic Unit: In this unit the coming instructions in the storage unit the A.L.U. calculates the instructions in the form of Arithmetic and logical to prepare output form results and after prepare the result the control unit is decides to sends the results to output unit to the resources.

What are the differences between an input device and an offline data entry device? Offline data entry device: i) The offline data entry devices are uses to data enters without online working. ii) The offline data entry device such as bio metric attendance device is uses generally take offline attendance then it will be able to send attendance data to attendance registrar officer. iii) Some software  services includes functions have they receives a data from bar coding to stores automatically fills data for accounting purpose as making bills receipt etc. iv) Some devices such as M.I.C.R., OCR , O.M.R. for a specific work for data entry work to safe the data of people privacy. v) Bar Code Reader is also an  offline  data entry  device to stores the data into some software for accounting purpose.  What is entering data on the computer? The entering data mean the data which is used to enter through the source document or other type of method to enter the data into the applic

What are the three main purpose of an operating system? There are three main purpose of an operating system. 1. The first main purpose is User interface between hardware and users. 2. The second main purpose is to operate the internal parts of the computer properly and systematically using binary code system in the form of 0 and 1. 3. The third main purpose is to provide an environment for development of an application software and program to uses the hardware resources of the computer and connected to the computer parts which provides output to the user, the output from application software is very useful for users. Interface between user and hardware device  The operating system uses all types of interface such as command line interface, batch command interface and Graphical User Interface to interact with users to hardware peripheral devices through the monitor screen. Monitor has a big role making interface between hardware and users. Monitor visualization of all types of o
