笔记本电脑的最大优势就是在于它可以随时随地进行信息处理和移动办公,但这个优势只有当笔记本电脑能够迅速地与外界进行信息交换才能得到最大限度的发挥。因此,高效迅捷地对外联络方式已经成为衡量笔记本电脑功能的一项重要指标。根据对外联络方式的不同,我们可以将笔记本电脑的连接方式分为有线和无线两种,前者需要使用到笔记本电脑上地各种端口或者内置/外置/PCMCIA 的调制解调器或网卡,而无线上网方式在目前比较流行的有 Bluetooth(蓝牙)以及802.11b等无线局域网接入技术。有线连接方式是计算机之间进行信息交换的最古老的方式。但随着技术的发展,它也衍生出了三种完全不同的类型:端口对端口,通过附加硬件进行信息通信以及复合方式。端口对端口方式中最常见的就是直接电缆连接,它采用电缆直接在两台计算机的并口或者串口之间建立联系,实现两台计算机之间的信息互访。此方法
The biggest advantage of the laptop is that it can carry out anytime information processing and mobile office, but this advantage only when the laptop can quickly exchange information with the outside world in order to get the maximum play. Therefore, efficient and expeditious contact with foreign countries has become an important measure of the functionality of a laptop. Depending on the external contact method, we can divide the laptop connection into two types: wired and wireless. The former requires the use of various ports on the laptop or a modem or network card with built-in / external / PCMCIA, and the wireless Internet access At present more popular with Bluetooth (Bluetooth) and 802.11b and other wireless LAN access technology. The wired connection is the oldest way of exchanging information between computers. But as technology has evolved, it has also spawned three completely different types: port-to-port, messaging through additional hardware, and compositing. Port-to-port mode is the most common direct cable connection, which uses the cable directly in the parallel port between two computers or serial port to establish contact between the two computers to achieve the exchange of information. This method
