Displayport: the Next Generation Interface for High-Definition Video and Audio Content
TA0339 Technical article DisplayPort: the next generation interface for high-definition video and audio content 1 Introduction Over the past decade, entertainment and communications in consumer electronics have moved to digital formats. Full HDTV, 3D gaming, 3D video, 4K x 2K screens, internet video, and IP-based video conferencing all require more bandwidth, increased memory, and improved connectivity between devices. As the digital ecosystem evolves, innovative interfaces are emerging in response to the new digital vistas that are opening up. Many of these interfaces are often driven by a single company or a small group of companies and are crafted in a way that, sooner or later, will require customers to pay royalties. DisplayPort is a VESA (Video Electronics Standards Association) interface standard for high-speed, high-definition audio and video. It has been developed by the VESA committee, with contributions from over 60 people from numerous diverse sectors: chip makers, cable makers, connector manufacturers, and computer and consumer electronics manufacturers. DisplayPort is free of charge and any VESA member can contribute towards its evolution. No fees, no royalties, just advanced technology. DisplayPort has become well known since its wide adoption by Apple, Dell, and HP; however, many people talk about DisplayPort without really knowing the underlying aspects of this standard. This article details what DisplayPort offers and helps readers understand why and how this evolving interface will co-exist with existing digital video and audio interfaces.

Welcome to Computer Basics
Computer Basics Instructor's Guide 1 COMPUTER BASICS To the Instructor Because of time constraints and an understanding that the trainees will probably come to the course with widely varying skills levels, the focus of this component is only on the basics. Hence, the course begins with instruction on computer components and peripheral devices, and restricts further instruction to the three most widely used software areas: the windows operating system, word processing and using the Internet. The course uses lectures, interactive activities, and exercises at the computer to assure accomplishment of stated goals and objectives. Because of the complexity of the computer and the initial fear experienced by so many, instructor dedication and patience are vital to the success of the trainee in this course. It is expected that many of the trainees will begin at “ground zero,” but all should have developed a certain level of proficiency in using the computer, by the end of the course. 2 COMPUTER BASICS Overview Computers have become an essential part of today's workplace. Employees must know computer basics to accomplish their daily tasks. This mini course was developed with the beginner in mind and is designed to provide WTP trainees with basic knowledge of computer hardware, some software applications, basic knowledge of how a computer works, and to give them hands-on experience in its use. The course is designed to “answer such basic questions as what personal computers are and what they can do,” and to assist WTP trainees in mastering the basics. The PC Novice dictionary defines a computer as a machine that accepts input, processes it according to specified rules, and produces output. -
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. -

When buying a computer with the intent to use it as a graphic workstation, Figures 1 and 2, there are several things to consider. The first is speed. Different computers work at different speeds. For digital graphics, you need a computer that is as fast as you can afford. You will be using files that are very large, and a slow computer may take quite a long time to accomplish normal tasks. The second is memory. Digital graphic files get large, and more memory will make even a slow computer seem as if it is Figure 2. -

Computer Fundamental
Computer Fundamental COMPUTER FUNDAMENTAL Ist Year Computer Engg. Page 1 Computer Fundamental Interconnection between Functional Components A computer consists of input unit that takes input, a CPU that processes the input and an output unit that produces output. All these devices communicate with each other through a common bus. A bus is a transmission path, made of a set of conducting wires over which data or information in the form of electric signals, is passed from one component to another in a computer. The bus can be of three types – Address bus, Data bus and Control Bus. The address bus carries the address location of the data or instruction. The data bus carries data from one component to another and the control bus carries the control signals. The system bus is the common communication path that carries signals to/from CPU, main memory and input/output devices. The input/output devices communicate with the system bus through the controller circuit which helps in managing various input/output devices attached to the computer. Ist Year Computer Engg. Page 2 Computer Fundamental Input Unit :The input unit consists of input devices that are attached to the computer. These devices take input and convert it into binary language that the computer understands. Some of the common input devices are keyboard, mouse, joystick, scanner etc. Output Unit : The output unit consists of output devices that are attached with the computer. It converts the binary data coming from CPU to human understandable form. The common output devices are monitor, printer, plotter etc. Central Processing Unit (CPU) : Once the information is entered into the computer by the input device, the processor processes it. -
Chapter 1 What Is a Computer
CHAPTER 1 WHAT IS A COMPUTER 1.1 Introduction It seems nowadays everyone has a computer or two and if not they are looking to buy one. The reasons people buy computers have become about as varied as the number of people buying them. We know computers can do a multitude of tasks, some to entertain, some more productive and some simply to pass the time. But just what is a computer? 1.2 What is a computer? A computer is an electronic machine that takes in data and instructions (input), works with the data (processing) and puts out information (output). This definition is further explained as follows: Computers are made of hardware: · input devices such as the keyboard and mouse · the central processing unit (CPU) and memory · storage devices such as hard drives · output devices such as printers and monitors And software (the instructions that tell the computer what to do): · system software · Programs (application software). A computer is a general-purpose machine that processes data according to a set of instructions that are stored internally either temporarily or permanently. The computer and all equipment attached to it are the hardware. The instructions that tell it what to do are the software. A set of instructions that perform a particular task is called a program or software program. 1.3 Generations of Computers The computer has experienced five generations, with the fifth generation still very much in development. · First Generation · Second Generation · Third Generation · Fourth Generation · Fifth Generation 1.3.1 First Generation This generation of computers was developed at the University of Manchester, England. -
Printers, Scanners, Cables, Etc.)
COMPUTER APPLICATION IN BUSINESS Submitted To:- Prof. Gulzar Ahmad Submitted By:- Usman Fazal (30209) Usman Anjum (30212) INTRODUCTION: A computer and the associated physical equipment directly involved in the performance of data-processing or communications functions is called computer hardware. Computer hardware is the physical part of a computer, including the digital circuitry, as distinguished from the computer software that executes within the hardware. The hardware of a computer is infrequently changed, in comparison with software and data, which are "soft" in the sense that they are readily created, modified or erased on the computer. Firmware is a special type of software that rarely, if ever, needs to be changed and so is stored on hardware devices such as read-only memory (ROM) where it is not readily changed (and is, therefore, "firm" rather than just "soft"). Most computer hardware is not seen by normal users. It is in embedded systems in automobiles, microwave ovens, electrocardiograph machines, compact disc players, and other devices. Personal computers, the computer hardware familiar to most people, form only a small minority of computers (about 0.2% of all new computers produced in 2003). Machinery and equipment (CPUs, disk and tape drives, modems, keyboards, printers, scanners, cables, etc.). In operation, a computer is both hardware and software. One is useless without the other. The hardware design specifies the commands it can follow, and the software instructions tell it what to do. The concept of inventing hardware to assist in commercial productivity is not new. For example, thousands of years ago the Chinese sought greater efficiency in calculating numbers, leading to the invention of the abacus, a hand-held mechanical device.
