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. -

s Class -IV Super Computer Year- 2020-21 1 1. Input and Output devices • Focus of the Chapter 1. Input devices 2. Output devices • Introduction The computer will be of no use unless it is able to communicate with the outside world. Input/output devices are required for users to communicate with the computer. An input device sends information to a computer system for processing. An input device tor a computer allows you to enter information. An output device can receive data from another device, but it cannot send data to another device. There are different devices of the computer that help it to do work. Input Devices The devices which are used to input the data and the program in the computer are known as "Input Devices". For the text input, keyboard are used, microphone is used for audio or sound input. 2 Keyboard The keyboard is the most common input device. A 'keyboard' is a human interface device which is "-presented as a layout of buttons. It is a text-based input device that allows the user to interact with the computer through a set of keys mounted on a board. Mouse After the keyboard, the mouse is the most common type of input device. A mouse makes the process of navigating the screen much easier than trying to use just a keyboard. A mouse usually uses a ball, light or a laser to track movement. Joystick A joystick is an input device consisting of a large pointed stick and input buttons on it. We can use this for playing games on the computer. -

How to Use Webcam & Microphone for Teleconferencing Input/Output
(760) 744-1140 ext. 2140 / [email protected] How To Use Webcam & Microphone for Teleconferencing • Webcams – Offer a video camera and microphone and use a USB plug. Resolutions options (in increasing order): 720p, 1080p, and 4k. They higher the resolution, the clearer the image will be, but will require more data usage to send and receive, which can be an issue for those with data-capped Internet plans or insufficient connectivity (poor WiFi signal, etc). • Headsets – Offer a feedback-free audio only solution. o Wired – Can use USB or 3.5mm (standard headphone) plugs. The USB models tend to be easier to set up, the 3.5mm models may require configuration settings to be changed on the computer. o Wireless – Use a USB dongle or Bluetooth connection. Allow the user to not have any cables, but will need to be recharged regularly. NOTE: Most of the desktop computer provided by Palomar do not have Bluetooth. • Microphone – Can use USB or 3.5mm plug. Offer better quality audio pickup, but can create feedback when used with speakers (which may be necessary for interactivity). NOTE: For audio-only solutions, Palomar College recommends a wired, USB headset. It will be the easiest to connect and use and will often the most reliable. They also tend to be more cost-effective than wireless options. Input/Output Configuration in Windows 10 Once an audio input/output device is connected to your computer, Windows should automatically make it your default device. If it doesn't please follow these steps to set the device as default: 1.
