 From a slow start computers have developed speed and complexity through which they can process billions of information per second and solve problems beyond practical human range. The first computing began simply with the abacus, a rectangular series of beads mounted on rods, used from at least 1100 B.C for basic arithmetic. 

    Basically computer science is a study of computers and computing their theoretical and practical applications. As a discipline computer science covers a wide range of topics, from theoretical studies of algorithms ,computations and information to practical problems implementing computing systems in hardware and software.   

    During the Renaissance, innovators from Leonardo da vinci to Gottfried Leibniz and Blaise pascal designed or built machines that could add and subtract. But the 1800s saw the first machines that could translate programmed instructions, store information, and branch through alternative processes depending on prior outcomes. Joseph-Marie Jacquard, a French weaver, developed a loom that used punched cards to execute complicated designs. In the 1820's Englishman Charles Babbage envisioned a steam-driven analytical engine that would store a thousand large numbers, decipher punch-card instructions, switch operations based on outcomes, and feed results to a printer.  Babbage's wonder was never built, but in the 1930's inventors like Howard Aiken and john Vincent Atanasoff began using vaccum tubes and electronic circuits to built increasingly powerful machines. They also experimented with expressing instructions in binary code. reducing information to 0s and 1s. The work culminated in the world-war II -era development by Alan Turing of the colossus, a code-cracking machine. In 1946, the room size Electronic Numerical Integrator and Computer (ENIAC) became the first modern computer in operation. By 1964, Integrated circuits helped move computers into the commercial world, with IBM's first mainframe office computer. A decade later microprocessors made machines faster and smaller.

Types of Operating System

Article by Prabhakar Published on
 Types of Operating System Batch Operating system Time sharing Operating system Distributed Operating system Network Operating system Real Time Operating system Multi programming/Processing/Tasking Operating system Mobile Operating System Batch Operating System               In a Batch operating system the similar jobs are grouped together into batches with the help of some operators and these batches are executed one by one. For example, suppose we have ten programs, some are written in c++ programming language, Some are written in c programming language and the rest are written java programming language. Now, every time we run these programs one by one, we have to load the compiler of that particular language and then run the code. But if we do a batch of these ten programs, The advantage with this approach is that for the c++ batch, you only need to load the compiler once. Similarly, for Java and C , the compiler only needs to load once and the entire batch is executed. The followin

Python Variables

Article by Prabhakar Published on
variables,the name itself implies that a variable is something which can change.  Variables are like containers for storing  our data values in memory. we can change the data in variables, in python everything is an object and variables are like names given to the object, by labeling them we can easily access them. In other high level languages like C programming language, c++ programming language, and java programming language. etc.,   we need to declare the datatype of the variable , but in python it will automatically recognize the type of data you are storing in a variable. ** Remember that a variable is a name which is given to a value not to the memory. Declaring a variable is very easy you need to assign a value or a string using '=' operator. >>> p=9 >>> print(p) 9 Assigning a single value to multiple variables We can assign a single value to multiple variables.  >>> a=b=c=56 >>> a 56 >>> b 56 >>> c 56 Assigning diff

Even or Odd Number and Factorial of a Number in Python Programming

Article by Prabhakar Published on
1. To Check if the given number is even or odd If a number is completely divided by 2 then it is even number. When the number is divided by 2, we use the remainder operator %  to calculate the remainder. If the remainder is not zero, the number is odd. SOURCE CODE:- n= int ( input ( "enter any number:- " )) if (n% 2 == 0 ): print (n , 'is even number' ) else : print (n , 'is odd number' ) OUTPUT 1st Run enter any number:- 2 2 is even number 2nd Run enter any number:- 3 3 is odd number In the above code we use "Simple if" statement.  In the above program, we ask the user for input and check if the number is odd or even. 2.Factorial number Factorial of a number defined as the product of all numbers from 1 to given number. For example  5!(5 factorial)=5*4*3*2*1 is 120. Note = factorial of 0 is 1 SOURCE CODE n= int ( input ( "Enter any number:- " )) fact= 1 for i in range ( 1 , n+ 1 ): fact=fact*i print ( 'factorial of' ,

DATA TYPES IN PYTHON | (Numeric,Boolean, Dictionary)

Article by Prabhakar Published on
Previous Variables in Python  In python programming language everything is an object and data type tells us which types of value the object is. Data types are classified into five types in Python programming language, they are:- Best Laptop for Web Development  in 2021. NUMERIC DATATYPES BOOLEAN DATATYPES DICTIONARY SEQUENCE DATATYPE SET type() method  Type method is used to know what type of data we are using. Numeric Data Types Numeric type consists of numerical value data types for example whenever we assign a decimal value or numbers to variables then it comes under numeric data types. It contains : int float complex type Int or Integer It is a data type where the value given by the user can be positive or negative and can be of any length that means it can be a big integer or small integer but it should not be a fraction or a decimal value. #Python Program to # demonstrate int value p= 5556677 print ( type (p)) q=- 45 print ( type (q)) #output < class 'int' > <

Functions of Operating System

Article by Prabhakar Published on
 Operating System is an interface between the user and the hardware and enables the interaction of a computer's hardware and software.          Also, an operating system is software that performs all the basic functions of file management, storage management, process management, managing input and output, and controlling peripherals such as disk, drivers and printers. Functions of Operating System Device Management  File Management Memory Management Process Management Mastermind Storage Management Handling input/output operations Security Functions of Operating System Device Management          Operating system manages device communication via their respective drivers.

Computer System Architecture

Article by Prabhakar Published on
 Based on number of general purpose processors computer systems are classified into three types.They are: Single Processor Systems. Multiprocessor Systems. Clustered Systems. Single Processor Systems From the name it is very clear that it has only single processor. A major central processing unit that can execute a set of general utility instructions, including user process instructions. There are some other special purpose processors present that performs device specific task. In the single processor system apart from the main central processing unit(CPU) there are also other processors which are present which does not do the general purpose task but it performs some device specific task. It means that we have a certain devices in our computers like keyboard, disk, etc. for all this they may be some microprocessor  which is specified to do a specific task related to that device like for example keyboard, when we press a key on our keyboard the keystroke has to be converted to some kin
