and manipulate dataThey are the smallest unit of data in a digital electronics deviceA bit can be a capacitor that is electronically charged or not charged.A bit can be an area of metal particles on the surface of a disk that are either magnetically charged or not.A bit can be a microscopic spot on a highly reflective disk surface that either has a pit burned into it or not.Chapter 3 Topics:Chapter 3 Outline/SummarySystem Software controls the hardware and runs the computer system.Application Software provides services for people.Software consists of a number of files at least one of which is “executable”.Executable File: stores computer instructions in binary machine language.programming language is the primary tool of computer programmers, providing English-like commands for writing software that is translated into the detailed step-by-step instructions executed by the processor.Chapter 4 Topics:E-commerce has opened up new opportunities in buying and selling.Chapter 5 Topics:Chapter 5 Outline/SummaryTelecommunications: The electronic transmission of signals over a medium for communications.Analog Signal: transmit sound using continuously varying levels of voltage.cellular network is a radio network in which a geographic area is divided into cells, with a transmission tower and station at the center of each cell, to support mobile communications.cellular carrier is a company that builds and maintains a cellular network and provides cell phone service to the public.Chapter 6 Topics:Chapter 6 Outline/SummaryCGS2060 Concept Exams #1Study Guide Chapter 1 Topics: • What can you use computers for- o combines hardware and software to accept the input of data, process and store the data, and produce some useful output• When you talk about something digital it references things that can be represented by numberso Bit- represents data using 1’s and 0’so Digitization is the process of transforming information into 1’s and 0’s• A group of 8 bits is called a byte• Things that can be stored on a digital device include numbers, characters, sounds, images, movies, etc. • Know what a special purpose computer iso A kiosk is a computer station that provides the public with specific and useful information and services.• Know the general definition of a computer networko A telecommunications network that connects two or more computers for data communications.o Telecommunications are communications that take place electronically over a distance• Know that Wi-Fi (short of wireless fidelity) is a popular wireless networking standardo Wireless networks use radio signals rather than cables to connect users.• VOIP (Voice-over-Internet-Protocol) is a popular technology that allows phones to use internet connections. • The speed of a human brain has been estimated at 100 trillion operations per secondChapter 1 Outline/Summary Computer- A digital electronics device that combines hardware and software to accept the input
