Concept 1 Test Chapter 1 1 The convergence of computer and network technology was responsible for the shift from the industrial economy to an information economy 2 Programs such as Internet Explorer that serve as navigable windows into the Web are called browsers 3 Transistors invented in 1948 replaced the vacuum tube 4 The first programmable general purpose digital computer was called the Z1 5 The World Wide Web has been around since the 1990s 6 The Electronic Numerical Integrator and Computer ENIAC broke down on average every 7 minutes 7 The software tools that enable a user to interact with a computer for specific 8 9 purposed are known as applications It is True that computers can threaten our privacy security and way of life It is true that supercomputers are the fastest most powerful computers made 10 Word processing applications are used for producing letters 11 Many laws and rules of organizations are reflections of moral principles 12 The Abacus is a calculating tool that had an immediate and profound effect on the human race 13 Transistors were invented in 1948 as a substitute for the vacuum table which appeared in computer 8 years later 14 PDA stands for Personal Digital Assistant 15 The first general purpose commercial computer built in the United States was called the UNIVAC 1 16 The special purpose computer that allowed British military intelligence to eavesdrop on even the most secret German messages was named Colossus 17 The silicon chip is the technological advancement that made it possible for computers to become as small as they are today 18 The Mark 1 computer proved its worth by computing ballistics tables for the U S Navy 19 Remember the golden rule is included in the guidelines of the ACM Code that might help you to decide how to do the right thing when faced with ethical dilemmas at school at work or at home 20 The ABC was the computer invented in 1939 that was capable of solving linear equations 21 Moore s Law predicted that the number of transistors that can be packed into a silicon chip of the same price would roughly double every two years 22 An example of biodigital technology would be a computer chip embedded 23 Many of the jobs that have existed for hundreds of years are no longer 24 A negative aspect of laptop computers is the relatively high price and in a person s body needed due to automation upgrade difficulties 25 The agricultural age lasted until about two centuries ago when advances in machine technology triggered what has come to be known as the industrial age 26 The ENIAC could calculate 500 times faster than the existing electromechanical calculators which was about as fast as a modern pocket calculator 27 In 1943 the founding father of IBM predicted that the world would not need more than 5 computers calculations 28 In the early nineteenth century a computer was a person who performed 29 Apple launched a new product called an iPad which is designed to bridge the shrinking gap between the smart phone and the notebook netbook PC 30 The future could bring the emergence of biodigital technology computer chips embedded within human bodies 31 A server is a computer that provides software and other resources to computers over a network 32 Computers have changed the way humans go about their day to day lives Events and ideas radically change the way people work live and think This dramatic change is known as a paradigm shift 33 When a student posts a clip from a recent movie on her Web site the ethical issue of the action is protecting intellectual property only this answer 34 Intel developed the microprocessor 35 In the early nineteenth century Charles Babbage and Ada Lovelace conceived an idea for a mechanical computer that they referred to as an Analytical Engine 36 Silicon Valley where numerous microprocessor manufacturing companies are located is in California 37 Computers grew out of a need to quantify 38 The time period in which there was a shift from an industrial economy to an economy based on the value of information is known as the information age 39 The World Wide Web WWW and the Internet are different because The WWW is a vast tract of the Internet and makes the Internet accessible to just about anyone 40 The most widely known code of conduct specifically for computer professionals is the Association for Computing Machinery Code of Ethics Chapter 2 1 Linux is an operating system 2 To save energy you can set your laptop to go to sleep 3 The word size of a typical PC s CPU is 32 or 64 BITS 4 A logical group of 8 bits is also known as an octet 5 Byte is used to represent one character on a computer 6 If a user needs information instantly available to the CPU it should be stored in RAM 7 The primary difference between RAM and secondary storage devices is the length of time data is stored 8 AMD produced the first 64 bit processor 9 The binary system uses the power of 2 10 Optical computing is sometimes called photonic computing because it uses photons instead of electrons to transmit bits 11 A special low energy kind of RAM that can store small amounts of data for long periods of time on battery power is known as CMOS 12 The time for the processor to retrieve data from memory is measured in nanoseconds 13 To represent values larger than 255 processor designers combine bytes Two bytes with 16 bits can represent all the numbers from 0 to 65 535 14 The CPU is often known as the microprocessor 15 When newer processors can process all of the instructions handled by earlier models the processor is considered backward compatible 16 A trackball is NOT an output device 17 CPU stands for Central Processing Unit 18 The CPU and main memory are housed in silicon chips on the motherboard and other circuit boards inside the computer 19 The memory used to store the computer s date and time while the computer is powered off is CMOS 20 The hardware device commonly referred to as the brain of the computer is the CPU 21 CMOS stands for Complementary metal oxide semiconductor 22 The design that determines how individual components of the CPU are put together and work together on the chip is called the architecture 23 A group of 8 bits is known as a byte 24 A petabyte is the largest storage unit 25 An advanced coding scheme that incorporates Arabic Chinese Hebrew and Japanese is known as Unicode 26 A notebook uses less energy than a desktop computer 27 Hardware components are physical parts of a computer system 28 ASCII stands for American Standard Code for
