Get to know the fundamental technology and concepts that make networking systems possible, including the software and hardware supporting LANs, WANs, and Wi-Fi networks with SOS Introduction to Network Systems. This CTE elective for students in grades 9-12 uses vivid graphics, videos clips, audio files, animation, and learning games to liven up lessons and clarify concepts.

了解使网络系统成为可能的基本技术和概念，包括支持局域网，广域网和Wi-Fi网络的软件和硬件以及网络系统时尚校舍的简介。 此CTE选修课为9-12年级的学生提供了生动的图形，视频剪辑，音频文件，动画和学习游戏，以激活课程并澄清概念。

Description

Introduce students to key network systems concepts, including the OSI reference model and its bottom four layers, each of which is explored in a three-lesson chapter. This six-unit CTE course for grades 9-12 teaches students to state the purpose of a computer network and explain the role of network hardware in achieving that purpose, list at least four protocols from the TCP/IP stack and explain how each contributes to data transmission.

In addition, this elective explains the technical differences between a LAN and a WAN, describes the importance of technical standards in networks, lists all seven layers of the OSI reference model, explains what each of the bottom four layers contributes to a network, and compares and contrasts the Windows Server and Linux operating systems.

描述

向学生介绍关键网络系统概念，包括OSI参考模型及其最底层的四个层次，每个层面都在三节课中探讨。 这个六年级的9-13年级CTE课程教导学生说明计算机网络的目的，并解释网络硬件在实现这一目的中的作用，列出TCP / IP协议栈中至少四种协议，并解释每种协议如何促成 数据传输。

此外，本选修课解释了局域网和广域网之间的技术差异，描述了网络中技术标准的重要性，列出了OSI参考模型的所有七层，解释了底层四层对网络的贡献，并比较了 并对比Windows Server和Linux操作系统。
