What is the actual need of this Presentation?. Lets answer to this question first……………….

Now what’s the content here?. Our Presentation has been divided into 4 parts….. Part 1 – W hat is a Computer? Part 2 – What are the Characteristics of Computer? Part 3- What are the Types of computer? Part 4 – What are the Components of Computer ?.

Now WITHOUT WASTING YOUR PRECIOUS TIME LETS WELCOME U ALL TO THE WORLD OF COMPUTERS................

WHAT IS A COMPUTER?. A computer is a device that transforms data into meaningful information. It processes the input according to the set of instructions provided to it by the user and gives the desired output. Computers are of various types and they can be categorized in two ways on the basis of size and on the basis of data handling capabilities..

1.Speed 2.Accuracy 3.Diligence 4.Versatility 5.Reliability 6.Automation 7.Memory.

LETS KNOW EVERYTHING IN DETAILS!!!.

Speed-. A computer works with much higher speed and accuracy compared to humans while performing mathematical calculations. Computers can process millions (1,000,000) of instructions per second. The time taken by computers for their operations is microseconds and nanoseconds ..

ACCURACY-. Computers perform calculations with 100% accuracy. Errors may occur due to data inconsistency or inaccuracy..

dILIGENCE -. A computer can perform millions of tasks or calculations with the same consistency and accuracy. It doesn’t feel any fatigue or lack of concentration. Its memory also makes it superior to that of human beings..

VERSATILITY-. Versatility refers to the capability of a computer to perform different kinds of works with same accuracy and efficiency..

RELIABILITY-. A computer is reliable as it gives consistent result for similar set of data i.e., if we give same set of input any number of times, we will get the same result..

AUTOMATION-. Computer performs all the tasks automatically i.e. it performs tasks without manual intervention..

MEMORY-. A computer has built-in memory called primary memory where it stores data. Secondary storage are removable devices such as CDs, pen drives, etc., which are also used to store data..

WHAT ARE THE TYPES OF COMPUTER?. So, on the basis of size, there are five types of computers: 1.Supercomputer 2.Mainframe computer 3.Minicomputer 4.Workstation 6.PC (Personal Computer) And on the basis of data handling capabilities, there are three types of computer: 1.Analogue Computer 2.Digital Computer 3.Hybrid Computer.

Now let us DISCUSS each type of computer IN DETAIL!!!.

SUPER COMPUTER-. It is used in the stock market or big organizations for managing the online currency world such as bitcoin etc..

MAIN FRAME COMPUTER-. It has high storage capacity and great performance..

Minicomputer-. Because of its low weight, it is easy to carry anywhere..

Workstation -. They are exclusively made for complex work purposes..

PC (PERSONAL COMPUTER)-. It is smallest in size..

One more type IS NOT MENTIONED BUT ITS VERY IMPORTANT FOR PRESENT TIME!!! LETS KNOW ABOUT IT !!!.

laptop. While portable computers used to be significantly slower and less capable than desktop computers, advances in manufacturing technology have enabled laptops to perform nearly as well as their desktop counterparts. In fact, high-end laptops often perform better than low or even mid-range desktop systems. Most laptops also include several I/O ports, such as USB ports, that allow standard keyboards and mice to be used with the laptop. Modern laptops often include a wireless networking adapter as well, allowing users to access the Internet without requiring any wires..

WHAT ARE THE COMPONENTS OF COMPUTER?. 5.Storage: Solid State Drive (SSD) or Hard Disk Drive (HDD).

THANKS TO EVERYONE FOR WATCHING THE FULL PRESENTATION HOPE U ALL LIKED IT !!!!.
