Optical multiplexing allows for sending multiple signals through a single medium as well as for bidirectional use of that medium. Device used for this purpose is called multiplexer. Wavelength-Division Multiplexing Based on Frequency-Division Multiplexing of radio waves. Multiplexers are also called Data Selectors. For example, telecommunication signals, Telephone signals etc.
However, in the foreseeable future, the classroom will still be the main way of teaching activities. The rapid development of information technology, to promote comprehensive education reform from the purpose, content, form, method to the organization. Standing in the first line education teachers, the teaching process is absolutely necessary to re-understanding. "Basic Education Curriculum Reform (Trial)" states: "vigorously promote the universal application of multimedia information technology in the teaching process, and promote the integration of information technology and curriculum, and the progressive realization of the presentation of course content, the way students learn, teachers changes in teaching methods and teacher-student interaction, and give full play to the advantages of information technology, to provide a variety of educational environment and a powerful learning tool for student learning and development. "Thus, the teachers use modern information technology, information technology plays an auxiliary unique features of teaching, to improve classroom teaching is an important idea of the current school reform.
Technology integration prepares students for the realities of living in digital era. It includes everything from frequent computer use in the classroom, where students learn how to effectively perform research using the internet and computers, to the use of technology such as smart boards, digital projectors and electronic textbook supplement. Technology integration is vital for classroom and structured education striving to keep up with advances to technology not only in the different ways that students can learn, but also in the ways in which they will be expected to utilize the knowledge and skills they learn. The utilization of computers and the Internet is one of the most common forms of technology integration found in many classrooms. This enables teachers to instruct students on how to effectively perform research using the Internet, as
Data literacy is the ability to derive meaningful information from data, just as literacy in general is the ability to derive information from the written word. The term data literacy is used to broadly describe the set of abilities around the use of data as part of everyday thinking and reasoning for solving real-world problems said by Gooch et al (2017). There are many story about the data literacy that can find and write in this term paper. Data literacy is a rapidly expanding field that is becoming necessary in most professional fields. Students will be able to collect, analyse and draw conclusions from the data are also prepared to further their academic achievement.
This chapter defines the mechanical and electrical interfaces of network and the three kinds of transmission media: Guided (copper wire and fibre optics), wireless and satellite. We will also discuss the key transmission technologies that are used in modern computer networks. 8.2 Physical communication media Communication media can be defined as material or techniques capable of carrying one or more signals through which data is transferred from one place to another. Network devices are connected to each other via actual physical environment on which data travels as it moves from one location to another. A media can referred to as physical media because the media is generally a physical object that can be touched and felt, and has physical properties such as weight and color.
Importance of Information Literacy Information literacy is important for today’s learners, it promotes problem solving approaches and thinking skills when asking questions and seeking answers, finding information, forming opinions, evaluating sources and making decisions fostering successful learners, effective contributors, confident individuals and responsible citizens. People need to be able to identify what is real and relevant not just for school but for learning, life and work. Information literacy skills have been around for quite some time in different guises and several frameworks and definitions have been produced both nationally and internationally. By using the information literacy it is was to finding and using information in all sorts of contexts, such
IEEE 802.11 Wireless Local Area Network Shubhangi Thakur Sachin Sharma Computer Science Department Computer science Department Shoolini University (H.P) India Shoolini University (H.P) India Shubhangithakur25@gmail.com Abstract:- This article contains a brief study on IEEE 802.11 Wireless LAN. Wireless communication is an application of science and technology that has come to be vital for modern existence. From the early radio and
Language education that contributes to learning to read and write, as well as literacy development such as knowledge about language, writing, verbal ability, and the ability to process information (Cviko et al., 2011). Technology integration. Applying computer technology, including its techniques and products, to facilitate the performance of school curriculum and pedagogy (Seels & Richey, 1994). Summary Different articles will be examined to find the effectiveness of technology integration to support emergent literacy skills. Different forms of technology integration will be examined to find if the technology can help educators take technology integration to a level that supports what research has shown to be beneficial.
The shared services can be a database, a file, a software etc. All interconnected computer must follow a set of communication rules for transmitting and receiving the data. the rules governing computer communication are called protocols. Every network includes: • At least two computers Server or Client workstation. • Networking Interface Card 's (NIC) • A connection medium, usually a wire or cable, although wireless communication between networked computers and peripherals is also possible.
Introduction Importance of Interactive educational environment History Key words Features of Interactive educational environment Types of interactive educational environments Distanced learning Advantages Disadvantages Conclusion Opinion Reference Introduction Interactive educational environment is the physical space where new technologies such as satellite systems, the Internet, multimedia, and interactive television among others; Are the tools, means and supports by which the teaching-learning process is developed. This new and innovative method of teaching goes beyond the traditional school environment that favors the knowledge and appropriation of contents, experiences and pedagogical-communication processes.
