第一句：
Reading and writing without caring where your data is coming from or where it's going is a very powerful abstraction. Among other things, this enables you to define I/O streams that automatically compress, encrypt, and filter from one data format to another.
在读写的时候不用关心数据从哪里来或者要被写到哪里去这是一个很强大的概念。
下面一句要怎么翻译呢？
第二句：
Finally, we'll look at the various APIs Java provides for low-level I/O through various devices including serial ports, parallel ports, USB, Bluetooth, and other hardware you'll find in devices that don't necessarily look like a traditional desktop computer or server.
这句话太长了，我不知道怎么翻译才好，请大家帮帮忙哦：）

除了这些以外，这使你能够定义I/O流，它能够自动压缩、加密和从一种数据格式转换为另一种.Finally, we'll look at the various APIs Java provides for low-level I/O through various devices including serial ports, parallel ports, USB, Bluetooth, and other hardware you'll find in devices that don't necessarily look like a traditional desktop computer or server.最后，我们看到，Java为多种设备提供的不同的低层I/O API，这些设备包括：串口、并口、USB、蓝牙及其他你能找到的但是在传统的桌面型计算机和服务器上不需要的设备。
