Speech on Computer
INTRODUCTION
A very good morning to one and all present over here . Respected guests and my dear friends , today I will be giving speech on the topic “COMPUTER”
BODY
Computer is an electronic device. First computer was invented by Charles Babbage in 1822. It was a great invention for modern technology. He invented digital computer known as analytical engine. At that time computers were only meant for calculations. The size of computer at that time was eleven feet long and seven feet high with 8,000 parts of weigh five tons i.e it covers a whole room. Later, as the time passed the size of computer decreased due to use of transistors instead of valve. A computer runs on a three step cycle- input, process and output. It consist of several parts such as CPU, motherboard, monitor, keyboard, RAM, hard disk drive, mouse, power supply, ROM etc. Each and every partof computer has different functions such as monitor is used to display all the data, CPU (central processing unit) is the brain of computer because it consist of an arithmetic logic unit and a control unit, motherboard control all computer circuits and it is an important part of computer and RAM is used to store short term memory. The computer parts are divided into two devices i.e. input (eg- keyboard, mouse) and output devices (eg- monitor, printer). Computer are classified into two categories- by architecture and by size and purpose. In this architecture computer includes analog computer, digital computer, von Neumann , Harvard computer and hybrid computer. But in daily use we generally use second type of computer that is size and purpose computer. This type of computer includes mini computer, mainframe computer, microcomputer, supercomputer. The microcomputer is a single user computer with less speed and low capacity of storage. For eg- personal digital assistant, tablet, desktop computers. In minicomputers, it has power less than mainframe but more than micro computer. The mainframe computer store large amount of data and can be used in banks, universities. The last one is supercomputer, it has enormous storage capacity with fastest speed among all types of computer. Computer are of great use such as for calculation, communication( messaging, video call), playing games, writing, making animation, audio video and photo editing, entertainment, making powerpoint slide, Notepad. Computers are used in the field such as defense, industry, education, banking, business, government, hospital, research field. Now a days, there is a large demand of software engineers as all the jobs are carried out by computers only. The skills which we can learn from computer is java, python, C++ , animations and coding. Some famous brands of computer are Hewlett-Packard (HP), Sony, Asus, Samsung, Lenovo, dell, apple & intex. But there are some disadvantages of computers such as bad effect on health ( especially eyes, brain and spinal cord), misuse, wastage of time by scrolling down a site, lots of distractions, cyber crime, loss of potential, limited learning, increases waste, polluting the environment, reduces the job opportunities. Other threats which incudes viruses, spams and bugs.
CONCLUSION
Today, the world is more depended on computer and in future computer can replace human being. It is a boon, don’t let it to become bane. Artificial intelligence is taking over the world, which is not very fortunate for the growing population. Computers should only be used where they are needed, and shouldn’t be used to replace the human workforce. Let’s use this as a resource.
