First things I want you to know about computer is computer is a machine that manipulates data according to a list of instruction.
Let me show you the history of computer, alright?
The first computer in the world was the chinese calculator, surprise? But the first useful computer is the ENIAC
ENIAC, short for Electronic Numerical Integrator And Computer, was the first general-purpose electronic computer. It was a Turing-complete, digital computer capable of being reprogrammed to solve a full range of computing problems. ENIAC was designed and built to calculate artillery firing tables for the U.S. Army`s Ballistic Research Laboratory.
But there is a big problem, its too big (bigger than your room) and calculate speed was not so fast. And it’s very expensive. Imagine you can buy a Rolls-Royce Phantom, a Bugatti Veyron, a Porsche, a Lamborghini… with its price. So it was only use in U.S.Army.
Remember! One big room! Argggggg
The most important thing in computer is the computer case. It contain all device or hard ware inside. If there is a problem with it, your computer cannot work properly. So beware!
Nowaday, there are variety design of computer case. I’ll show you some design of computer case.
Popular design
OOOHHH! This is a computer case, isn’t it?
And Gotcha! That’s what I want!
AHHHHH! So COOOOOOOOL
Whenever we think about computer, what is the first thing we think about? Guess what? Right, It’s the visual display unit.
A visual display unit, often called simply a monitor or display, is a piece of electrical equipment which displays images generated from the video output of devices such as computers, without producing a permanent record. Most newer monitors typically consist of a TFT LCD, with older monitors based around a cathode ray tube (CRT). Almost all of the mainstream new monitors being sold on market now are LCD. The monitor comprises the display device, simple circuitry to generate and format a picture from video sent by the signals source, and usually an enclosure. Within the signal source, either as an integral section or a modular component, there is a display adapter to generate video in a format compatible with the monitor.
And here is some picture of modern monitor. Prepare to shock! (I wont show you the CRT monitor, its too…agraah!
Shock!?
Ok! Now, I’m going to show you about the thing I used to type this article. I think you know what is it, right? It’s the keyboard.
There are many kind of keyboard. Hardware computer made it for every purpose. For example: There is a special kind of key board called gamer keyboard for gamers who want their keyboard is the fastest keyboard for every shots. There is a cute kind of keyboard called girls keyboard, you guess what is it for? Right, It’s for girls who want their keyboard not only cute but also colorful, etc. See, there are many many kind of keyboard so I can’t show you all it this presentation, if you want more, contact me later, alright? Let’s take a look at some of my picture!
That’s about the keyboard. But there is a hardware more important than the keyboard. It’s the mouse. Is it this one?
Yo! U can call me ur babeee!
Applause! It’s so kute!
Wow, it’s so cute, right? Nope, but its not the mouse I want you to know. My mouse is a computer mouse.
In computing, a mouse (plural mouses, mice, or mouse devices) is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user`s hands, with one or more buttons. It sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations, or extra buttons or features can add more control or dimensional input. The mouse`s motion typically translates into the motion of a pointer on a display, which allows for fine control of a Graphical User Interface.
Like keyboard, there are many kind of mouse and now, I will show you guys some kinds. Watch!
Call of duty 4
Ok! You know all the basic things about computer, now, I will teach you about the computer’s appliance.
Computers can be use in many things and very helpful. There’s no company in the world doesn’t have computers. In factory, computers are used to control the machine; In hospital, computers are used to heal weak people by dr or nurse, etc.
Yea, computers are very helpful not only in work but also it help people entertain, connect people to the world so that the world is more dynamic. It make people find their own style in their life, make them happy; it make the world’s funnier, more joyful. And its help many people indulge with work, help many students find their pesonality, find their job…
Do you like game on personal computer (PC)? I’m sure you will say you do like game. I’m not going to teach you what does games mean, I think you know it clearlier than me. But I will teach you about how does computer’s entertainment is not so good for people, especially students.
Games and another way to entertain are not so bad, it depend how do people use it for. If you play game all day, your brain would so tired, but you can’t stop, almost games are so addictive. Then, you will waste your time to play unuseful computer game. Can you have any time for your work, your heath, your personal life of all your times are used to sitting in front of computer’s screen? This is so bad!
Computer help people connect to the world so you will be easy to download or upload, share your file with the world. But everythings always have advantages and disadvantage, not except this situation. What are the disadvantage? It’s you can download everythings from internet, but not all internet’s information are not objectionable. Beware!
So you guys knew all about the computer’s advantage or disadvantages, right? Now tell me your idea. What do you think about the life without computer? Can you live without it ? I think there will be many opinions. with us, right? Many people think that a life without computer is such a boring life, they don’t have anythings to do. Althought many people think that they can live without computer. And my opinion is we CAN’T live without computer. Because it is so important. But you need to travel to some famous lanscapes to relax your mind. Remember it!
And I have some advice for students: It’s you have to balance time your life, real life , your work and time for entertain with computer. Computer is good but it’ll become bad depend user’s purpose. Be the smart user, man!
Ok! That’s all my presentation. I think it’s not so good, but anyway,thanks for watching!
Now, let’s relax with my favorite song, alright? Here we go.
