Digital Technology & Electronics

1. Digital Technology & Electronics Enables us to manipulate all types of information as digits (1s and 0s). Why? Because we can store and manage the information efficiently and effectively, then use it creatively as we need it. Links: Video: What sets Curosity apart from other Mars Rovers?

2. Digital Literacy It has become a requirement for most careers. Today DIGITAL LITERACY is closely aligned with financial opportunity and independence. In this section: Computers & Literacy, Bits/Bytes, Digitization, Character Encoding, Value Encoding/Binary Number System and Digital Convergence Links: Video: One Laptop Per Child Concepts> Digital Technology > Digital Literacy

3. Computer A digital electronics device. It combines hardware and software to accept the input of data. It will process and store the data to produce useful output. In todays world, it can be represented by a variety of devices. Computers have transformed the world, bringing some good -and some bad. 5 Primary Functions: Computation Automation Communication Entertainment Managing Information Links: I ROBOT Concepts> Digital Technology > Digital Literacy > Computer

4. Computer Literacy Computer literacy refers to a basic, fundamental understanding of computers and their uses. Computer fluencycaptures the essence of business expectations across a variety of devices. • Today’s college graduates are entering the workforce as knowledge workers. They are expectedto add value to the information economy. Concepts> Digital Technology > Digital Literacy > Computer Literacy

5. Bits and Bytes A bit (short for binary digit) is a digit that can be 1 or 0. A bit is the smallest unit of information a digital electronics device can manipulate. Group eight bits together to have a byte. How BITS represent information is key to understanding the workings of computers and digital devices. KB = Kilobyte Kb = Kilobit Bits are stored on CDs and DVDs by burning pits in the disk surface Concepts> Digital Technology > Digital Literacy > Bits and Bytes

6. Digitization Digitization, (digitizing)is the process of transforming information. This can be text, images, or sounds, into digital representation. (Those 1s and 0s) It can then be stored and processed by computers and used many ways. Computers have become a part of so many things we do because we have learned to digitize MANY different types of information.

7. Character Encoding Several standards have been designed for character encoding. This is the representation of characters on the keyboard with bytes, most having roots in the earliest standard called ASCII (American Standard Code for Information Interchange).

8. Value Encoding/Binary Number System Many number systems are used for value encoding - the representation of values with numbers. The binary number system, which uses only two digits, 1 and 0, is commonly used for representing values in computers.

12. The use of battery-powered mobile devices providing access to computing, communication, information, and/or entertainment anywhere, anytime. In this class, we will refer to tablets and smartphones as mobile devices and to smartwatches and glasses as wearable technologies. Mobile Computing & Wearable Devices Mobile Computing Technologies are dependent on: Wireless Networks, Storage, Servers, Syncing and Rechargeable Batteries Links: Video: Apple iWatch Trailer (Official Trailer) (Apple Watch) Concepts > Digital Technology > Computing Platforms > Mobile Computing

13. Apowerful computer that can utilize many processors to provide services to many users simultaneously over a networkfor custom solutions. Server The term “server” has replaced other older terms, such as minicomputer, midrange computer, and mainframe computer, used to describe various sizes of servers. Servers are typically designed and purchased for a particular purpose. Concepts > Digital Technology > Computing Platforms > Server

14. The most powerful type of computer, often utilizing thousands or even tens of thousands of processors to solve the world’s most difficult problems. Supercomputers assist humanity in extending our intellectual capabilities through massively powerful computation. Supercomputer Supercomputers are also used to simulate the functioning of the brain to create artificial intelligence, just one example of their incredible power.

15. Computers designed to meet a specific need and are more prevalent, yet less noticeable, than general-purpose computers. Special-Purpose Computer They are embedded in consumer electronics, appliances, medical equipment, and a host of other devices. Referred to as embedded systems, and sometimes microcontrollers, these special-purpose computers are designed to control the electronics devices in which they reside.
