Chapter 2Networking and information technologyRounded rectangle: regular pivot units When personal computers were in use. The software is designed for various users.And there are a few programs that are used to connect personal computers, many. The technology is currently does not support the connection. When the computer is active more and more developers develop software that is more complicated, and supports multiple users work. This is why companies see the importance of connecting several computers together in a network system. Communication of data or of the information between the computer has become what the computer industry must give priority. Networking technology, it is technology that has the most growth in the computer industry needs a large network systems. Safer and more efficient.Rounded rectangle: puzzling story to study Networking, Internet, history of the Internet. The meaning of networking. The characteristics of the network connection. Types of network systems. The application of network system in Government The meaning of the role of information technology information systems. The use of computer information system The application of information technology. The impact of information technology.

Rounded rectangle: Unit 2 network and information systems. Network system. Networking, Internet The Internet is a computer network system at large can do multiple computer connections. The machine into the Internet, which is known to connect compatible communication standards of the internal (Protocol), which is the same computer that logs on to the network to the Internet can send and receive information to each other around the world, such as text, images, audio, video and audio both also can find information over the network to the Internet with speed. Just a few minutes, it can be made to find the information you need. Flowchart: alternate process: questionsCountries where Internet access is the maximum and minimum speed is what. Reserved words: answersHong Kong has high speed Internet access in the world. To a second country Mbps 42.73 Cayman Islands Speed Internet Thailand are countries ranked 36.47 59 Mbps speed in Mbps Internet connection, 8.72.And the country of Nepal is the final ranking is an Internet speed that 0.95 Mbps. The history of the Internet.อินเทอร์เน็ตเริ่มต้นมาจากผลจากสงครามทางการเมืองในยุคสงครามเย็น เมื่อ พ.ศ.2510 โดยมีฝ่ายคอมมิวนิสต์และฝ่ายเสรีประชาธิปไตย ซึ่งมีสหรัฐอเมริกาเป็นประเทศผู้นำกลุ่มเสรีประชาธิปไตย และรัสเซีย เป็นฝ่ายคอมมิวนิสต์ทั้งสองประเทศต่างคิดกลัวในเรื่องของขีปนาวุธนิวเคลียร์ที่เข้ามาถล่มจุดยุทธศาสตร์ของทั้งสองประเทศ ซึ่งจะส่งผลให้ระบบคอมพิวเตอร์ที่เชื่อมต่อกันนั้นเกิดความเสียหาย กระทรวงกลาโหมของสหรัฐอเมริกาจึงได้เริ่มโครงการวิจัยและพัฒนาเครือข่ายคอมพิวเตอร์ขึ้นเมื่อเดือนมกราคม 2512 โดยให้ชื่อโครงการว่า ARPANET (Advanced Research Projects Agency Network) ซึ่งมีจุดมุ่งหมายในการวิจัยและพัฒนาให้เกิดระบบเครือข่ายข้อมูลแบบกระจายศูนย์ ซึ่งจะทำให้ได

Chapter 2
Networking and Information
rectangle with rounded corners: the essence of the unit when the personal computer was used. various software Is designed for users with little programming used to connect multiple personal computers. The technology at that time did not support the connection. When a computer is used more and more software developers have developed a more sophisticated and capable of running multiple users. This is why firms The importance of connecting multiple computers together into a network. Communication or transmission of information between computers has become the PC industry need to focus. Networking technology is a technology that has the most growth in the computer industry and thus the demand for bigger, faster networks with greater security. And more efficient rectangle with rounded corners: to learn about the Internet network. History of the Internet means the network. The nature of the connection network of networks. Application of the network system in the State and the implications of information technology. The role of information systems, computer information systems. The application of information technology, the impact of information technology rectangle with rounded corners: behavioral objectives , students can study first. Explain Internet network has two.

Impact of information technology on the rectangle with rounded corners: Performance Unit knowledge about networking and information rectangle with rounded corners: two units at the network and the information network Internet network Internet. The computer network at large can connect multiple PCs. Combine them together and is known Internet connection compatibility within standard communication (Protocol), which the computer into the Internet network can transmit data to each other around the world, such as text, images, audio, send pictures. and You also can find information via the Internet very quickly. Only a few minutes to find the information they need to plan the sequence of work: backup process: The country with the speed limit is the country's reserves: Answer Hong Kong have Internet speeds in the world to 42.73 Mbps secondary. down a Country Andorra Internet speeds of 36.47 Mbps, Thailand is ranked 59th in Internet connection speed is 8.72 Mbps and the final ranking. Nepal has a speed of 0.95 Mbps Internet address of the Internet The Internet started as a result of the political war in 2510 when the Cold War with the Communist Party and the Liberal Democratic Party. The United States is the leader of Russia's Liberal Democratic and Communist parties both countries think that the issue of nuclear warheads to attack strategic points of the two countries. This will result in a system of interconnected computers that damage. US Department of Defense has started research and development network, computer on-month in January 2512 by the name of the ARPANET (Advanced Research Projects Agency Network), which aims to research and develop a network of distributed data centers. This will make the
