It is important to be able to recognize and name the major components of a PC for the following three reasons: • Computers are important network-building devices. • Many networking devices are themselves special-purpose computers, with many of the same parts as normal PCs. • For you to view the online curriculum, your own computer must be in working order, which means that you might need to occasionally troubleshoot simple problems in your computer s hardware and software. | Cisco Systems Cisco Networking Academy Program Engineering Journal and Workbook Volume I Second Edition Instructor Guide Cisco Networking Academy Program Engineering Journal and Workbook Volume I Second Edition Engineering Journal and Workbook Questions and Answers Chapter 1 Computer Basics Introduction It is important to be able to recognize and name the major components of a PC for the following three reasons Computers are important network-building devices. Many networking devices are themselves special-purpose computers with many of the same parts as normal PCs. For you to view the online curriculum your own computer must be in working order which means that you might need to occasionally troubleshoot simple problems in your computer s hardware and software. Concept Questions Demonstrate your knowledge of these concepts by answering the questions in the Engineering Journal space provided. The transistor and the integrated circuit made modern computers possible. Explain why. The invention of a semiconductor transistor opened up many possibilities for making smaller more reliable computers. Millions of transistors can now be placed on one small piece of semiconductor. Further microminiaturization of integrated circuits leads to widespread use of PCs in homes and businesses. If your computer doesn t power up what steps might you take to identify and correct the problem If your computer does not power up as expected consider verifying the following Power cord is plugged into wall socket. Power switch is switched to the on 1 position. Motherboard power inlet is securely fastened. 1 - 239 Engineering Journal and Workbook Vol. I 2nd Ed. - Chapter 1 Copyright 2002 Cisco Systems Inc.
