This standard defines a test access port and boundary-scan architecture for digital integrated circuits and forthe digital portions of mixed analog/digital integrated circuits. The facilities defined by the standard seek toprovide a solution to the
6端口接收机 IEEE收录论文 this paper describes the basic six-port theory and sets it into relation with the conventional receiver architectures such as the homodyne and heterodyne receiver. Finally, the advantages and possible applications of receivers based
802.1x 协议是一种基于端口的网络接入控制协议（port based network access control protocol）。“基于端口的网络接入控制”是指在局域网接入设备的端口这一级对所接入的用户设备进行认证和 控制。连接在端口上的用户设备如果能通过认证，就可以访问局域网中的资源；如果不能通过认证，
Features Simple and clean C++ interface. Uses C++ exceptions in preference to the normal win32 return value mechanism. This ensures that code which uses CSerialPort is more robust. Unicode enabled, supports linking to MFC statically and all code com
This chapter describes how to configure the Spanning Tree Protocol (STP) on port-based VLANs on the Catalyst 3560 switch. The switch can use either the per-VLAN spanning-tree plus (PVST+) protocol based on the IEEE 802.1D standard and Cisco propriet
IEEE 802.1x 称为基于端口的访问控制协议（Port based network access control protocol）。基于端口的访问控制（Port based network access control）能够在利用IEEE 802 LAN的优势基础上提供一种对连接到局域网（LAN）设备或用户进行认证和授权的手段。通过这种方式的认证，能够在 LAN 这种多点访问环境中提供一种点对点的识别用户的方式。这里端口是指连接到LAN的一个单点结构，可以是被认证系统的MAC地址，也可
IEEE 802.1X is the standard protocol for allowing hosts and users to be authenticated to the network before obtaining a connection (port-based network admission control). As well as providing very effective access control to wireless and other netwo
虚拟串口的实现 原理说明 how to convert Universal Serial Bus (USB) to a serial port without changing the application in order to realize the function of virtual serial port , which is based on the ACM f unction of CDC.
Port-based authentication is a "network access control" concept in which a particular device is evaluated before being permitted to communicate with other devices located on the network. 802.1X Port-Based Authentication examines how this concept can
