Being able to maintain, upgrade and troubleshoot your computer: Being computer literate means knowing which technologies are on the horizon and how to integrate them into your home setup when possible.;Being Prepared For Your Career1. Information Technology (IT) is a field of study focuses on managing and processing information and the automatic retrieval of information: Includes computers, telecommunications, and software deployment.Computers in Today’s Careers1. Retail- Working in a data mine: Data mining- the process of searching huge amounts of data with the hope of finding a pattern. 2. Great for managing inventory of products.3. Example – Amazon and Netflix can suggest items that fit your taste. 4. Arts: Ink, Paints, and a Notebook?- Must sell your work- Adobe Programs5. Video Game Design: A long Way from Pac-Man- Game development will most likely stay in in the United States instead of being offshored, like other programming jobs.- Mastering software animation tools to create new worlds.6. Education: Teaching and Learning- Research Tool- Give students a taste of running a global business.- Virtual tours7. Law Enforcement: Put Down That Mouse – You’re Under Arrest!- Computers in cop cars- Facial Reconstruction systems- Have a huge database to compare similar crimes to look for patterns.- Computer Forensics is a growing field.- Computer-based training to tech officers to recognize lies and evasive behavior.8. Military Careers-Drones9. Agriculture: High-Tech Down on the Farm- Outbreaks can be managed and minimized with the use of Radio identification Tags- Chip in a cow’s ear. If it’d as having a disease it will be tracked in a database.10. Automotive Technology- More efficient cars with higher gas mileage means increase in the number of sensors and computer systems needed in a typical vehicle. - Cool goods like digital music systems.- Technicians must be able to update documentation through the internet, through databasesto learn about common problems and solutions.11. Medicine- Braingate translates thoughts into commands to the robotic limb.- Patient simulator (Mannequins)- Physiome Project will allow image scanning combined with sample of the DNA to make an exact model of a body for experimenting.- Robots to perform surgery.12. Medicine: The Chip Within- Cells cultured on a chip until it formed with a nearby cell.- The chip contains a transistor that stimulates the touching cell that sends the pulse through the body. (Sight to the blind)- VeriChip – Personal Id Chip- In baby’s bracelets to locate position13. Science: Simulating Reality- Tornado forecasting, Model the structure of solar magnetic flares- Recreating ruins on screen. 14. Sports Science: Computer your way to a better game- Video recordings.- Software measure the exact angles of the athlete’s body parts as they progress through ranges of motion.15. Nanotechnology: Careers Yet to come- Nano science – Involves the study of molecules and structures that range in size from 1 to 100 nanometers.- Nanotechnology- Using nanostructures to build devices on an extremely small scale.16. Psychology: You Should Smile… Now- Affective Computing_ is computing that relates to emotion or deliberately tries to influence emotion.- ESP – for Autism (relays peoples mood)- Get people back on track and focused.Understanding the challenges facing a digital societyChapter 2: Looking at Computers1.Computers Are Data Processing Devices- A computer is a data processing device that performs four major functions 1. It Gathers data 2. It processes that data into information. 3. It outputs data into informationWhat is the difference between data and information? - Data- is a representation of a fact, a figure, or an idea. It can be a number, a word, a picture, or even a recording of soud. - Information- is data that has been organized or presented in a meaningful fashion. When data becomes meaningful.- Processing data into information.Bits and Bytes: The language of ComputersHow do computers process data into information? - The language of computers is binary code.- A binary code is broken into binary digits, called bits.- Eight bits combine to form a bytes.- Kilobytes- 1,000 Bytes- , Megabytes- 1 million bytes.- ,Gigabytes.- 1 billion bytes- Your computer uses a combination of software and hardware to process data into information. - Hardware- physical parts that can be touched.- Application Software- Set of programs such like mircosoft word. - System Software- a set of programs that enablesyour computers hardware devices and application software to work together.a. Most common type of system software is the Operating System.b. The program that controls the way in which your computer system fuctions.Your Computers Hardware- A peripheral device- a component such as a monitor or keyboard, that is connected to the computer.- Mainframe- Large computer that supports hundreds of users simultaneously. - Supercomputer- specially designed computer that can perform complex calculations extremely rapidly. Runs a few amount of programs as quickly as possible.- Embedded Computer- a computer chip that resides in another device. They are self contained computer devices that have their own programming that do not receive input from you or interact with other systems.Input Devices- A stylus is an input device that looks like a pen but has no ink .Use to draw on a screen. - Most desktop computers come with a QWERTY keyboard. - Dvoark keyboard puts the most commonly used letters in the English language on home keys in the middle row of the keyboard. - Flexible keyboards use Bluetooth technology to make a lazer
