Chapter 3- Using the Internet: Making the Most of the Web’s Resources
Working and Playing on the Web
The Origin of the Internet Objective 3.1 Describe how the Internet got its start. Storing Data and Information Objective 2.12 List the various types of hard drives. Hard drives The hard drive is a nonvolatile storage device, meaning it holds the data and instructions your computer needs permanently, even after the computer is turned off. Internal Hard drive The internal hard drive is your computer’s primary device for permanent storage of software and files. SSD drives have no moving parts so they are more energy efficient and less susceptible to damage. External hard drives are essentially internal hard drives that have been made portable by enclosing them in a protective case and making them small and lightweight. Cloud Storage
- Objective 2.13 Define cloud storage, and explain how to use it. refers to nonvolatile storage locations that are maintained on the Internet (in the “cloud”). Examples are OneDrive, Google Drive, and Dropbox. Storing your data in the cloud allows you to access it from almost any computing device that is connected to the Internet.
Portable and Optical Storage Options Objective 2.14 Describe the various portable and optical storage options. Learning Outcome You will be able to explain how the Internet works and how it is used for collaboration, communication, commerce, and entertainment purposes. Optical drives that can read from and write to CD, DVD, or Blu-ray discs are another means of permanent, portable storage. Flash drives are another portable means of storing data. Flash drives plug into USB ports. Flash memory cards let you transfer digital data between your computer and devices such as digital cameras, smartphones, video cameras, and printers. Connecting Peripherals to the Computer Objective 2.15 List the common types of ports used today. Ports The fastest type of port used to connect devices to a computer is the Thunderbolt port. The most common type of port used to connect devices to a computer is the USB port. Connectivity ports, such as Ethernet ports, give you access to networks and the Internet. HDMI ports are the most common multimedia port. They are used to connect monitors, TVs, and gaming consoles to computing devices and handle both audio and video data. Audio ports are used to connect headphones, microphones, and speakers to computing devices. lOMoARcPSD| Adding Ports Objective 2.16 List the options for adding ports to your device. Expansion cards can be plugged into the motherboard on desktop computers to add ports. Expansion hubs can be plugged into existing ports to provide additional ports of the
The origin of the internet Objective 3.1 Describe how the Internet got its start. Why was the Internet Created? all Who Invented the Internet? Evolved from U.S Gov- funding project called Advanced Research Projects Agency Network Vinton Cerf and Robert Kahn developed the communications protocols today So are the web and the Internet the same thing? Web Only a subset of the internet Based on Hypertext transfer protocol (HTTP) Common communications protocols that enable computers to talk to each other and display info in compatible formats Special links that enable users to navigate from one place to another on the web Who created the web? Began in 1991 Based on a protocol developed by Tim Berners-Lee o Wanted a method for linking his research docs to other researchers who could access it How does the internet work? Internet Acts in one of two ways o Either it’s a client: a computer that asks for data o It’s a server: a computer that receives the request and returns the data to the client o Internet is referred to client/server network Internet backbones: the transmissions lines with the fastest speeds How do computers talk to eachother?
The Internet was created torespond to these two concerns: establishing a secure form of communications and creating a means by which computers could communicate. V Objective 3.4 Summarize how e-mail and instant messaging are used to communicate over the web. V Objective 3.5 Describe the different types of e-commerce. V V E-commerce the business of conducting business online. includes transactions between lOMoARcPSD| Client and servers (amazon example) How does the data get sent to the correct computer? Computer is assigned to a unique identification number Number called an Internet Protocol Address(IP) Collaborating and Communicating on the Web Objective 3.3 Discuss the tools and technologies used to collaborate and communicate on the web. Web 2. the social web, in which the user is also a participant Examples of web 2.0 social networking, blogs, wikis, podcasts, and webcasts.
Navigate and view web pages ie: Microsoft edge, firefox, google, chrome, safari Learning Outcome 3.2 You will be able to describe the tools and techniques required to navigate and search the web. Accessing and Moving Around the Web Objective 3.9 Explain what a URL is, and discuss its main parts. URL You gain access to a website by typing in its address, called a Uniform Resource Locator (URL). several parts, including the protocol, the domain, the top-level domain, and paths (or subdirectories). Objective 3.10 Describe tools used to navigate the web. Tools used to navigate the web One unique aspect of the web is that you can jump from place to place by clicking on specially formatted pieces of text or images called hyperlinks. You can also use the Back and Forward buttons, History lists, and breadcrumb trails to navigate the web. Objective 3.11: Describe tools used to mark websites for future use. Tools used to mark websites -marked the start of the personal computer boom lOMoARcPSD| Favorites, live bookmarks, and social bookmarking help you return to specific web pages without having to type in the URL and help you organize the web content that is most important to you. Searching the Web Effectively Objective 3.12 Describe the types of tools used to search the web and summarize strategies used to refine search results. A search engine set of programs that searches the web using specific keywords you wish to query and then returns a list of the websites on which those keywords are found.
used to search for images, podcasts, and videos in addition to traditional text-based web content. Metasearch engines search other search engines. Using the Web Ethically Objective 3.14 Demonstrate an understanding of intellectual property and cyberbullying. Intellectual property result of someone’s creativity and knowledge. Youtubing illegally taking the artistic intellectual without giving credit Cyberbullying bullying with digital technologies. Technology in Focus 1- The History of the Personal Computer The First Personal Computer: The Altair Objective 3B.1 Describe the earliest personal computer ever designed. The altair The apple I and II Apple I -in 1975 -no keyboard, no monitor, and completely not user friendly -Steve Jobs, who was working for computer game manufacturer Atari at the time, liked Wozniak’s prototypes and made a few suggestions. Together, the two built a personal computer, the
