A desktop is a portable computing device featuring a touch-sensitive screen that can be used for input as well as for output. A slate tablet configuration is basically a screen in a narrow frame that lacks a physical keyboard. True 3. Page 3 b. Smartphones evolved from basic cell phones and PDAs. The operating systems for smartphones are radically different to those used for tablet computers. Smartwatches are multifunction devices that can include a camera, thermometer, compass, calculator, cell phone, GPS, media player, and fitness tracker.
Computers with the same operating systems can typically use the same software and peripheral devices. The Intel i7 microprocessor is x86 compatible. False 4. ARM-based processors are not especially energy efficient. The term instruction cycle refers to the process in which a computer executes a single instruction. During an instruction cycle, all parts of the instruction are performed by the microprocessor's control unit.
Most computer ads specify the speed of a microprocessor in gigahertz. A multicore processor that executes more than one instruction at a time is referred to as a parallel processor. Page 5 RAM is volatile. A hard disk drive is an example of magnetic storage. Solid state storage stores data in erasable, rewritable circuitry, rather than on spinning disks or streaming tape.
Memory cards are typically volatile. A solid state drive can be used as a substitute for a hard disk drive. All remote storage is considered to be cloud storage. When a peripheral device is connected or disconnected while the host device is operating, it is called hot-plugging.
True 6. Page 6 b. In a display device, response rate is the time it takes for one pixel to change from black to white then back to black. A laser printer has a nozzle-like print head that sprays ink onto paper to form characters and graphics. Which of the following is based on computer technology?

Relatively low cost for lots of storage c. Access time b. Data transfer rate c. Bitrate d. Which optical storage technology stores data permanently on a disc, which cannot be subsequently added to or changed. Read-only b. Recordable c.
Rewritable d. Page 11 Which of the following is NOT drawback of using cloud storage? Increased security risk. High price of storage. Offline access ensures students never miss a chance to learn.
Help students focus on what they need to study: Students can make their Pearson eText their own by creating highlights with meaningful labels and notes. The customizable Notebook lets students easily filter, arrange, and group their notes in a way that makes sense to them. Engage learners with compelling media: Videos and animation s bring key concepts to life, helping students place what they are reading into context.
Available with select titles. Let students check their understanding: Personalized Study Tools are easy to access on both the web and mobile app to help students learn key terms.
Help students see how reading is relevant to the course: Notes and highlights allow educators to share information directly with students within their eText.
Gain insight into how students use their eText: Reading analytics let educators see how students work in their eText so that you can plan more effective instruction. Quickly set up and access your course Straightforward setup makes it incredibly easy for educators to get students up and running quickly on the first day of class. Provide an affordable option: Pearson eText delivers the same high-quality content of a print book at an affordable price. New to This Edition.
Chapter updates keep the text current Several chapters and discussions have been revised for the 11th Edition, including: A discussion of multichip modules MCMs , has been added to Chapter 1.
A chapter on memory hierarchy expands on material that was in the cache memory chapter and adds expanded coverage of both the principle of locality and the memory hierarchy. The cache memory chapter Chapter 5 now includes expanded treatment of logical cache organization, including new figures, to improve overall clarity.
Coverage of content-addressable memory , write allocate, and no write allocate policies have been added to Chapter 5. Table of Contents I. Introduction 1. Basic Concepts and Computer Evolution 2. Performance Concepts II. The Computer System 3. The Memory Hierarchy: Locality and Performance 5.
