Under EAJA, a prevailing party is entitled to an award of fees and other expenses incurred in a civil action brought by or against the United States, unless the court finds that the position of the United States was substantially justified or that special circumstances make an award unjust.
Modem - Box from your ISP that connects to the internet. It actually connects to the phone line or the coaxial cable or whatever physical line you have. It normally has at least an ethernet connection, sometimes a USB as well. Router - Box that connects to the modem and allows multiple devices to use that internet connection at the same time. It also lets the devices talk to each other (so you can transfer files in your house or whatever).
A modem is a network hardware device that modulates one or more carrier wave signals to encode digital information for transmission and demodulates signals to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used with any means of transmitting analog signals, from light-emitting diodes to radio. A common type of modem is one that turns the digital data of a computer into modulated electrical signal for transmission over telephone lines and demodulated by another modem at the receiver side to recover the digital data.
