some typical application. The report will start with an overall introduction to wide area network‚ and then identify the key characteristics of this technology. Generally‚ the data transmission rate of wide area network is lower than local area network (LAN)‚ but with the development of technology‚ this data transmission rate is improved dramatically‚ it could achieve 2.4 Gbps or even higher currently. Thus‚ it could meet a great number of requirements. After that‚ it will analyze the key technologies

In many languages‚ the fundamental unit of composition is the paragraph. A paragraph consists of several sentences that are grouped together. This group of sentences together discuss one main subject. In U.S. formal academic English‚ paragraphs have three principal parts. These three parts are the topic sentence‚ body sentences‚ and the concluding sentence. We will also talk briefly about details in paragraphs. The Topic Sentence A topic sentence usually comes at the beginning of a

This unit explores these devices along with their transmission methods and the underlying protocols that enable connectivity and transmission of data including signal theory and data elements. Learners will appreciate why particular transmission methods are chosen for particular situations and be able to compare the effectiveness of the different methods. Finally‚ learners will be able to use their

spaces such as meeting rooms and auditoriums filled with people and communication is not secure because signals can be intercepted. Technology for solving such problems includes the use of the person body as a signal path for communication. A transmission path is formed automatically when a person comes into contact with a device and communication between mobile terminals begins. Table of Contents 1.
