The document discusses key aspects of how the internet works, including:
- The internet connects millions of computers globally through wired and wireless links, allowing people to search for information, communicate, and be entertained.
- Domain names provide human-friendly addresses for websites, while IP addresses are unique numeric identifiers for each device; domain names point to IP addresses.
- Packet switching breaks data into packets that contain sender/receiver addresses and are routed independently and reassembled at their destination via the most efficient path.
- Routers read packet addresses and direct traffic along the least busy route between networks to deliver packets to their destination quickly and efficiently.The internet

The document discusses several key aspects of how the internet works:
1) It explains that the internet is a global network of interconnected computer networks that uses standard protocols to share information worldwide.
2) It describes the relationship between domain names and IP addresses, noting that domain names provide a user-friendly web address while IP addresses are the underlying binary codes that computers use to locate sites.
3) It discusses how data is broken into packets and sent over networks through packet switching, with routers deciding the fastest paths for data packets to reach their destinations.What exactly is the Internet and how does it work

The Internet is the largest global network of interconnected computers. It connects millions of computers through local and wide area networks. The World Wide Web is a system of interlinked webpages accessed via the Internet. Webpages are stored on servers and displayed to clients using web browsers. HTML code provides the basic structure and formatting for webpages, while URLs specify the locations of individual webpages. The Internet has evolved from a US military network to a global information system with over 2 billion users.What exactly is the internet, and how

A network connects two or more computers together to share resources like files and printers or allow electronic communication. Computers on a network can be connected by cables, phone lines, wireless technologies or other methods. Local area networks (LANs) connect computers within a small geographic area like a school while wide area networks (WANs) connect larger areas like cities or countries together and can include the global Internet. Key benefits of networks include increased speed of file sharing, lower software costs, easier upgrades, improved security and access to electronic mail and remote access to files from different locations.Internet

The Internet is a global system of interconnected computer networks that use standardized communication protocols like TCP/IP to link billions of devices worldwide. It originated as a US military network called ARPANET in the 1960s and was later opened to universities, businesses and the public. The World Wide Web, created by Tim Berners-Lee in the 1980s, made the Internet much easier to use and browse, fueling its mass adoption. Today the Internet connects over 4 billion devices and its growth continues to accelerate as more people and organizations get online through broadband connections.What is internet

Computers started becoming popular with businesses in the 1960s and widespread in homes and schools in the 1980s. People now use computers for many purposes like banking, education, research, engineering, design, law enforcement, the military and more. Computers require both hardware, like processors, memory, and peripheral devices, as well as software programs and operating systems to function. Early pioneers invented the foundations of modern computers, but it was not until integrated circuits and transistors that computers became small enough for personal use in the 1970s and 1980s.Art Project - Perspective and Portraits
Art Project - Perspective and Portraitsthatjessicagirl
Ìý
During the Middle Ages, paintings were flat and did not show perspective or relative size accurately for objects in the foreground versus the background. The Renaissance introduced new techniques for showing depth and perspective through relative size differences. Artists now painted portraits and other subjects with objects appearing larger when closer and smaller when further away, similar to how the human eye perceives depth and distance. This new style of painting with linear perspective took off during the Renaissance and changed the field.CTE Computer Basics

There are several types of computers including supercomputers, mainframes, and mini-computers which are used to process large amounts of information for things like weather prediction, satellite images, and military scenarios. Personal computers, also known as PCs, are smaller and less powerful and are used in homes, schools, and small businesses. There are desktop, portable, and hand-held personal computers. A network connects computers together using wires or wireless to share hardware and information. Computers have two basic parts - hardware which are the tangible parts like the case, CPU, monitor, and storage devices; and software which are the programs that tell the computer what to do like operating systems and applications.Tec 571 e portfolio final presentation
