COMPUTER INFO

     The term "computer" is derived from Latin word "computare" which means to calculate, such as the abacus and slide rule.A computer is a programmable device that can store, retrieve, and process data. Computer was invented by Charles Babbage in 1837. Charles Babbage is also known as the father of computer. Modern computers have the ability to follow generalized sets of operations, called programs.There are two types of programs:-  Application program and  System program. These programs enable computers to perform an extremely wide range of tasks. Today's computers are electronic devices that process data as input and produce some data as output, and store the data as a results. Top 10 uses of computers[Daily Life] 1. Education field 2.

     Hello friends, Today we will learn computer science and about his work placement and salary in India. Computers are a part of nearly every aspect of modern life, which is why computer science is such an important field of study. The profession is projected to grow 19 percent from 2016 to 2026 as the demand for new and better technology grows.  Computer Science is the subject of computers and computational systems. The field of computer science deals with data and how that data can be manipulated to solve problems. Unlike electrical and computer engineers deal mostly with software and software systems; this includes their theory, design, development and application.Computer Science design and analyze algorithm also include artificial intelligence, computer systems and networks, security, database systems, human computer interaction, vision and graphics, numerical analysis, programming languages, software engineering, designing applications that perform ...

Change Account Password From Command Prompt   This method is more suited to advanced users and can be used in scripts and batch files.If you do not have administrator access to the computer you will not be able to change the password. 1. Open an Administrator Command Prompt by clicking on Start or pressing the Win key and typing command prompt, then hold Ctrl+Shift and press Enter. 2. Type one of the following commands into the prompt and press Enter and Type “net user” without arguments for a list of user names. 3. This will simply change the password for the username you specify using the password you entered. For example, net user Ram12345. Make sure to put the username or password in quotes. 4. then confirm password change.   This last command will create an 8 character random password for you and display it in the console window. The new password will be a mixture of uppercase, lowercase and special characters so make sure you memorize or note...

     Cloud Computing is a practice of using a network of remote servers hosted on the internet rather than a local server or a personal computer to store, manage and process data.You can access the pre-installed application and system software from anywhere on any device. It means cloud hosting, remotely hosted server, so that you can host your website and the world can access it from any device.An example of a Cloud Computing provider is Google's Gmail . Gmail users can access files and applications hosted by Google via the internet from any device and cloud storage such as Google Drive, Onedrive, Dropbox etc. Uses of Cloud Computing:- For users, Cloud Computing is an operational technology in which computer/mobile/tablet users can store, calculate, arrange, manage, host, create, publish, delete, share, edit and manipulate remotely hosted system software and applications software’s,  Data & Information by using the Internet. Cloud computing be...

    Hello gays welcome to my blog, Today we will know how the software works in computer. Computer software is a collection of data or computer instructions that tell the computer how to work(software is a set of programs). When you buy a computer the computer comes with the operating system(OS) and some software already installed. Hardware is important thing in computer,can't perform software without Hardware.The computer will not work without software.When the program is in use, the computer reads it from the storage device and temporarily places the instructions in random access memory (RAM). There are two types of software −   1. System Software   2. Application Software. System Software:- The system software is a collection of programs designed to operate, control, and extend the processing capabilities of the computer and its devices itself.The system software also called the operating system (OS) .Example of OS:-  Application So...

     Hello Guys Welcome to my blog, if you are planning on streaming or recording your Gameplay, minimum requirement for Computer parts(under budget).  When it comes to making a gaming computer then this parts are needed-     Motherboard     Processor (CPU)     Memory (RAM)     Storage drive (Hard drive or SSD)     Graphics Card (GPU)     Power supply (PSU)     Cooling (fans, CPU cooler, etc.)  The best Ram for gaming is a crucial component to the rest of your build, influencing everything from your CPU to your graphics. Without the best DDR4 RAM your whole system is stifled. With it, you can accomplish so much more at once.
