- 1. BRIDGE THE GAP! Outreaching to unite our divide
- 2. Binary Language • A Bit is represented in 0s and 1s • 8 bits = 1 byte • 8 bits/1 byte is used to encode a single character of text in a computer
- 3. Byte Sizes Kilobyte(KB) = 1024 bytes Megabyte(MB) = 1024 KB Gigabyte(GB) = 1024 MB Terabyte(TB) = 1024 GB Petabyte(PB) = 1024 TB
- 5. Examples of INPUT DEVICES
- 7. Motherboards The spine of your PC What is needed for all you components to work together Houses the CPU, RAM, connects the GPU, speaker, fans, USB ports, etc.
- 8. MEMORY(RAM) Pretty much required; without it everything would really slow. Acts as computer’s short term memory RAM stands for random access memory Used for not only DESKTOP PCs, but for Laptop, phones, game consoles, etc.
- 9. Processors(CPU) CPU stands for Central Processing Unit The Brain of the Computer Instruct the rest of the hardware through the motherboard
- 10. STORAGE Used to store the OS, files, and programs on your computer Ranges in various sizes, both physically and storage size Two types of storage are HDDs, and SSDs There are also SD cards, and external Hard drives as well
- 11. Computer Ports Connects device to your computer Usually positioned in the back of the tower. On the side of the motherboard.
- 12. Computer Ergonomics Sitting poorly can greatly impact your body negatively., as we unconsciously stress our bodies everyday Poor seating refers to slouching, extending wrists, and not having proper foot support Better Ergonomics make you be able sit comfortably
- 13. Thank you for tuning in and Happy Computing
Editor's Notes
- Computers uses binary language in the form of bits, or digits, that becomes information in a digital form. A computer bit is called a binary value, are usually represented as a number. Bits can be either a value of 1 (one) or 0 (zero), 8 bits will form a byte, and will typically become an alphanumeric character. T o determine the byte, the “1” bits act as an “on”, while the “0” bits act as an “off”, the combination of the “on” and “off” bits, determine the character. https://www.lifewire.com/the-difference-between-bits-and-bytes-816248 Photo:https://www.sciencefriday.com/wp-content/uploads/2015/08/hello.png
- A byte is comprised of 8 bits, and can be represented as an alphanumeric character. One character would be worth 8 bits or one byte, two characters would be 16 bits or two bytes, three would 24 bits or 3 bytes, and so on. The more characters you have the more the byte size, once you have over 1024 bytes in size, it would be represented as a KB(or kilobyte), which follows that trend in higher sizes. http://myrepono.com/faq/4 Photo: https://i2.wp.com/www.computersnyou.com/wp-content/uploads/2013/02/up2.jpg?resize=300%2C168&ssl=1
- Supercomputers and Mainframes are the fastest and most powerful computers, as well as the most expensive. Supercomputers are used huge number crunching and simulations, animated graphics, and calculations. Mainframes are multi-user computers that supports hundreds to thousands of users at once concurrently. Minicomputers are just like mainframes, as they are multiprocessing computers that support up to 200 users at once. A Personal Computer is a single user computer on a micro processor, and they tend to run Windows, Mac, or Linux OSes. Laptop ands Notebook are PCs, that are built for mobility they tend to be downclocked for less power consumption to the battery. Tablets and smartphones, are designed to be even smaller and compact handheld computers. They tend to run either the Android OS or Apple’s iOS. https://www.cs.cmu.edu/~fgandon/lecture/uk1999/computers_types/ Photo: https://slideplayer.com/slide/4667094/15/images/2/Types+of+Computers+Tablet+Essential+Computer+Concepts.jpg
- Input devices are devices that you connect to your computer, via USB, in the case Keyboards and mice, PS/2 or USB, to send data to the computers, to interact with…. or control it. Keyboards and Mice the standard and necessary, if you want to access and control your computer; unless you have a touchscreen. A touchscreen, allows you to be able to interact with the computer with yours fingers. A scanner optically “reads” an image of a physical picture or document, copies the image, and send it as data to the computers as a image file; allowing you to save it as any image format(i.e.JPG, PNG, etc). Microphones allows users input audio to their computers, as webcams captures pictures, or motion video of the user, or anything that is facing the webcam’s camera. Joysticks or controllers are used as inputs to play video games on your computer. https://www.computerhope.com/jargon/i/inputdev.htm Photo: https://4.bp.blogspot.com/-1vgeh7hv74Y/WZlcOO-zMlI/AAAAAAAAJho/TIfweI0mGBE5wsEADurDDt0dAggSeTOLwCLcBGAs/s1600/examples%2Bof%2BInput%2BDevices%2Bof%2BComputer.png
- Output devices are peripherals that receive data from the computer. it’s usually for display, projection, or physical reproduction. Monitors display data from the computer, and comes in a variety of sizes and resolutions. Speakers and Headphones play audio from the computer. Speakers are for broad open sound, while headphones are for personal ear use. . Printers copy images or documents from the computer, and on physical papers. https://www.computerhope.com/jargon/o/outputde.htm Photo: https://4.bp.blogspot.com/-CksCxFPd8QM/VsyZ6D1_wHI/AAAAAAAAAAs/0KMwSmf91-w/s1600/Output-Devices.jpg
- The Motherboard acts as a hub for all the other components to connect together. It houses the CPU, which act as a brain, as well as the other hardware components to function with one another. https://www.ebuyer.com/blog/2013/12/what-does-a-motherboard-do/ Photo: https://static.gigabyte.com/Product/2/6242/2017021610381208_big.png (The motherboard I use)
- RAM, or Random Access Memory, stores information the computer needs immediately, Ram allows your computer to load up everything you need very fast. They come in various sizes, both physically(for different devices), and in storage. They can come at different amounts such as 4 GB, or 8 GB sticks, but they also come at different confirmed speeds, such as 2133mhz, to upwards of 3400mhz. The higher amount of storage, and the fastest stable speed, the better, but check CPU compatibility. https://www.digitaltrends.com/computing/what-is-ram/ Photo: https://im9.cz/iR/importprodukt-orig/5db/5dbc5bcb13cc880a0fd24a902f677322.jpg (The ram I use)
- The Central Processing Unit is the main brain of your computer, as it tell the other component what to do, and when to do it. It makes all the priority decisions. There are plenty of processors in the market, and they run at different MHz speed, and IPC, depending on the architecture generation. The two main CPU company in the desktop space are AMD, and Intel. http://www.hardware.windowsreinstall.com/processor.htm Photo: https://images.idgesg.net/images/article/2018/05/cpu-hub-100758206-large.jpg (I use Ryzen!)
- Typical Storage devices in Computers are HDD(Hard Disk Drives), and SSD(Solid State Drives). They store digital data from the internet, as well as storing your OS, and all of your programs, games and other applications. SSDs has advantages over HDDs, while being more expensive. M.2 drives are a little faster than traditional SSDs, and NVMe drives, while looking similar to M.2, are by far the fastest storage one could have, and probably the most expensive too.. https://www.computerhope.com/issues/ch001396.htm Photo: https://cnet4.cbsistatic.com/img/ONG0nOFT4pqsUeUqU2DlkmJ2NCM=/770x578/2014/04/24/5c7bea3b-a3a6-441f-b17c-86ee060127d4/dsc0065.jpg
- Computer ports are connection point for the computer to communicate with internal or external device. Some ports are USBs, which connect a wide variety of devices like microphones, webcams, keyboards, mice, etc. HDMI, VGA, DVI, and DisplayPort’s are meant to connect display video output to your monitor, HDMI support Audio, and video output. Keyboards and Mice also have PS/2 ports ass well, for older models. There are Lan ports as well, that connect to an internet, and hard wires you to the internet. https://www.techopedia.com/definition/3659/computer-port Photo: https://i.ytimg.com/vi/qoOHC6QM4bQ/maxresdefault.jpg
- Ergonomic is a study aims to reduce strain, fatigue and trauma to your body, and aims for a comfortable and relax seating posture. It done by rearranging your workspace, and making it work for you. https://www.uhs.umich.edu/computerergonomics Photo: https://www.uhs.umich.edu/files/uhs/ergo.jpg
