Chapter 1 PC Architecture
Chapter PC Architecture THE FOLLOWING OBJECTIVES ARE COVERED IN THIS CHAPTER: 1 1.1 Identify the names, purpose, and characteristics, of system modules. Recognize these modules by sight or definition. 1.5 Identify the names, purposes, and performance characteristics, of standardized/common peripheral ports, associated cabling, and their connectors. Recognize ports, cabling, and connectors, by sight. COPYRIGHTED MATERIAL A personal computer (PC) is a computing device made up of many distinct electronic components that all function together in order to accomplish some useful task (such as adding up the numbers in a spreadsheet or helping you write a letter). By this definition, note that we’re describing a computer as having many distinct parts that work together. Most computers today are modular. That is, they have components that can be removed and replaced with a component of similar function in order to improve performance. Each component has a very specific function. In this chapter, you will learn about the components that make up a typical PC, what their function is, and how they work together inside the PC. Unless specifically mentioned otherwise, throughout this book the terms PC and computer can be used interchangeably. The components in most computers include: The case The power supply The motherboard The processor /CPU Memory Storage devices The adapter cards Display devices Ports and cables As you read this chapter, please keep in mind that many of these parts will be covered in more detail in later chapters. Figure 1.1 shows an example of a typical PC and illustrates how some of these parts fit together. -
PS1 and PSA Inverters TN0021: Connecting to Modem Or Direct Connect
15/10/2008 PS1 and PSA Inverters TN0021: Connecting to modem or direct connect This document describes the methods for configuring modems and cables for use with Remote Link software for PS1 and PSA inverters. Note that while PS1 are commonly displayed or referred to in this document, PSA inverters are handled similarly. To communicate with a modem, the inverter must be configured correctly using either; 1. Dial-up modem, over a phone line 2. Direct cable connection Remote Link is available at http://www.selectronic.com.au/remotelink. To configure an inverter for dial up modem connection: The PS1 or PSA inverter must be connected to a modem. Selectronic currently supplies and supports only the Netcomm AM5698. The modem must first be programmed with specific settings or it will fail to communicate. Programming can be done using the “Program a modem for PS1 use” utility, which comes with the Remote Link software. Attach the modem to be programmed to a COM port on your Windows Computer. Start the utility and select the correct COM port. The default settings are usually suitable for most modems. Click the Write button to program the modem. The utility will write all the settings required and save them in permanent storage. Once the function is complete, close the utility and disconnect the modem. Attach the modem directly to the inverter, using the special RJ45 lead. Turn on the PS1 inverter. Turn on the modem. Verify that the Terminal Ready light is illuminated immediately, and does not go out 2 seconds after power up. Correct connections at the computer’s modem If you are using a laptop which does not have a serial port, you will need a USB to serial adaptor, as displayed below. -

f 1 This chapter covers the following subjects: II Understanding liD Ports-This section describes the types of 110 ports used to send information to and from the processor and memory. II Understanding Input Devices-This section describes the important characteristics of keyboards, mice, biometric readers, and other input devices. II Understanding Display Types-This section describes output devices such as CRTs, LCDs, and data projectors. II Understanding Video Connector Types-This section talks about com mon video connectors such as VGA, DVI, and HDMI. II Printing Fundamentals-This section describes the basics of laser, inkjet, impact, and thermal printers. .. Understanding Multimedia Devices-This section covers the basics of multimedia devices such as webcams, digital cameras, lV:1IDI ports, micro phones, sound cards, and video capture cards. CHAPTER 3 1/0 Ports and Devices Input/output (lIO) devices enable us to control the computer and display infor mation in a variety of ways. There are a plethora of ports that connect these de vices to the computer, for example, the well-known USB port. To fully understand how to install, configure, and troubleshoot input, output, and multi media devices, you need to know the ports like the back of your hand. In this chapter you learn about serial, parallel, SCSI, USB, sound, and FireWire ports and their corresponding devices; the goal is to make you proficient with the var ious interfaces you see in the IT field. Understanding 1/0 Ports The word "port" is used often in the computer industry, and has many different meanings depending on what technology is being referred to. -

NEAR EAST UNIVERSITY I I ,/,, Faculty of Engineering Department of Computer Engineering VISUAL BASED TTL GATE TESTER Graduation Project COM-400 Student: Yunus KURTOGLU Supervisor: Assqc. Prof. Dr. Dogan IBRAHIM • Nicosia - 2001 ACKNOWLEDGMENT Firstly, I have to send my thanks to my supervisor Assoc.Prof.Dr.Dogan IBRAHIM for his helps. Secondly, I would like to express my gratitude to Near East University for the scholarship that made the work possible. Finally, I have to say thanks to my friend Latif NiZiPLi. I designed my hardware with him. And also like to thanks all other my friends for their advice and support. ABSTRACT Standard TTL logic gates are very important in logic design circuits. This project is a personal computer based TTL gate tester project. The project consists of a hardware where the gate to be tested is mounted on and connected to the parallel port of a standard personal computer. A Visual Basic program, developed by the author, enables the user to select the gate type and then the gate is tested and user is informed whether or not the gate is faulty. The project can be used to test simple 14-pin 74 series logic gates. • ii TABLE OF CONTENTS ACKN'OWLEDGMENT , i ABSTRACT ~ ii TABLE OF CONTENTS iii LIST OF ABBREVIATIONS ··················~··································································V IN"TRODUCTION 1 Chapter 1 USING THE PARALLELPORTS .....•........•.........•......•.......................•.... 3 1 .1.
