3 Who Is The Boss? Have you ever wonder whats happening inside the computer? Have you ever wonder who is controlling the computer? Well you may think that electricity is just going through wires, but much more is happening and it start with the boss. The CPU. It may look like a small chip but inside tons and tons is happening. There is a bunch of wires is carrying a code called binary. Binary is a language filled with 1s and 0s. So if type in A, the CPU will turn that in to binary.

4 Name Some Parts CPU it controls the computer Hard drive it stores data several hard magnetic disc Ram it holds on the information the CPU will need later Rom it hold on the information the computer needs permanently Video Card it turns data into images on the screen Sound Card it turns data into sound Motherboard it put everything together Buses wires on the motherboard that plugs all of External Software Software that is outside the computer Internal Software Software inside the computer Software instruction for the computer Internal Storage the memory inside the (DSD) DSD data storing device External Storage the memory outside the (DSD) USB 2.0 it has only 4 data ports USB 3.0 it has only 5 data ports If 1 of these systems fail all will fail to.

5 Where Are All Of My Files? Do you need to save your homework or a family photo? But have you ever wonder where does it go? Well it goes to the hard drive. The hard drive has several hard magnetic disc. An arm goes over the disc while it is spinning. The arm make north and south magnetism. So north meaning 1 and south meaning 0. It can also go to SSD card. A SSD is a bigger version of the SD card. SSD's are very quiet. They are 3 types of SSD, single stage, dual stage, and triple stage. Single stage keep 1 byte of data in each cell. Dual stage keeps 2 bytes of data and triple stage keeps 3 and higher bytes of data. There is 1 more that I forgot to tell you. Flash drives. They are cousins of the SSD, but they can hold more data/bytes. They can hold about 6,000 novels. This is a 32GB Solid State Disk This is a DELL 1TB hard drive

6 ROM &RAM This ROM chip help the computer start up. Have These little chip help the RAM save data you ever wonder what happens in the computer during a start up? You may think the computer is just making 1's and 0's, but a part called the ROM helps during this time. It hold the information that is needed permanently. RAM is a chip that store data and release. Think of the ROM & RAM like your brain. ROM is where you would keep important stuff, like your name or Your mothers face. RAM is where you would keep short term things, like a type of food. ROM & RAM are total opposites because they store data in different ways and time.

7 The Video Card Ever kid likes to play games, but have you every wonder what makes those 2D and 3D graphics? This powerful machine called a video/graphics card. It works by grouping polygons together. But not all computers have it. Some computers have something called a APU. It is a CPU and a graphics card mixed together. APU's can display graphics faster than a connected video card. The polygons need to be shaped into one of these dimension: 2D & 3D. 2D is only length and width but 3D is length, width and depth. Triangles, rectangle and spares are examples of 2D shapes. And cubes and cones are 3D shapes.

8 3D Printers 3D printers aren't printers that you cant throw into the cart. The printers that can create 3D sculptures for doctors, scientist and even engineers. It all begins with a stock. A stock is like raw material. Raw material is thing like This is a 3D printer plastic, glass even chocolate. Yummy. Doctor can use 3D printers to make models of the human body. First a computer sends the request to a 3D printer. Next, the printer make stack one on top of the other. Finally, WAMMOO. Your 3D object is made. But 3d printer software isn't like 2D printer software. You need to go to a collage of engineering to know how to use the software. Some people find a way to get 3D models without using the software. These 3D models are sent to people by mail. First, they go on a website. Next, they order that item. Finally, you get that item. These websites can print, Niky shoes, high heels, even windows. 3D printers can't print things with lots of moving parts. You will be able to make the parts individually, but you would need to assemble it yourself.

9 2D Printers Have you wonder what happens when you click print. Yes, you may think the a bunch of 1's & 0's are going to a printer, but have you though deeper? Here is what happens, the printer drive is activated to print something. The drive send the message a to This is a HP 1200 Laser Printer This is an Epson 5500 Ink-jet printer the printer. The printer decodes the message and prints. Now you may be asking for more details so I will. Lets start with the ink-jet. When the printer gets the command it begins a production called inking. Inking is the process when the printer calculates where, is each color going to go. Next, the printing happens, and little boxes called cartridges spray ink onto the paper. The cartridges have tiny heaters on little tubes. These heaters make heat making pressure in the tubes. And a bubble of ink from then, it shoots out onto the paper. Laser printers have a 1% similarity with ink-jets printers. Data goes into the printer but that is when the similarity ends. The data is fed into a laser and then the laser light hit a drum. The drum has a negative charge. Toner stick on the negative charge of the drum. When paper passes by the drum rolls the toner onto the paper. And the amazing thing is that this happens in less than 30 seconds.

10 Robots You might have be thinking of the talking, walking, strong robots, but I am talking about the scientific and mass production robots. Robots are like moving computers. They can go to Mars or make a Honda car. They are many types of robots. A spider robot is built to collect lava rock. But some robots can be used at home like vacuum robots, they bump into walls to find there way. Or toy robots for kids, Zoomer, Boomer, Mip, and Spiro. Most robots have sensors (sen-ser). Sensors help robots calculate there location. They are two ways a robot can sense, infrared and physical. Infrared senors can receive a remote rays or receive the temperature of nearby objects. Physical sensing is when a push sensor senses a bump. Then the sensor knows there is an object nearby. Robots don't need CPU's. They require a control unit. The control unit of course controls the robot. It gives instruction to a specific part of the robot. Like the motor. The best thing about robots is that they can do dangerous tasks without getting harmed. They don't need air or food. Robots are helpful in lots of ways. You can think of robots as dead-alive computers.

11 Internet name}.com. You always type this into your computer but, do you know what this is? That is called the URL. When you type the URL into your computers search engine than a little spark happens. First your ISP contacts the DNS for the IP ADDRESS. The DNS is like a phone book for computer to use to find websites. The IP address is almost like an address that you use to find place. But instead of letters a IP address looks like this After the ISP receives the IP address it search is for that server through a wire called the backbone. That wire is the high speed line that connect you to the world wide web. The ISP continues searching until it find the server. Than the server send the website back to the backbone to your computer. And the amazing thing is that this only happen in half a second. Well if you have fast internet.

12 DVD'S & CD'S Do you love to watching movies or listening to music and wonder, how do they work? Well they work in the same way. Don't believe me. Well get a microscope. And than you will see bumps. These bumps are used to encode whatever is on the disc. For example if you put a song on the CD the bumps would have to mean a part of the song. Each bump equals a 1 or 0. When the computer reads these bumps it can do what the disc commands the computer to do. After this a window will show called Auto Play. Auto play is a program which asks the owner/user what to do with the data on the disc? This will only show if you have Windows from Microsoft.

13 Conclusion To wrap it all up, computers are able to do any task like search online without a user. Computers are controlled by a CPU. Most of the computers file are in the DSD. There are 2 types or printer. The 2D and 3D printer. The video/graphics card create the display that shows on the screen. And the internet is just a line with 1,000 computers and servers on it.
