example of a port expander is a USB hub. Most USB hubs allow you to hook up 3 to 5 USB connections from only 1 USB port on your computer. The disadvantage of using a port expander is speed. The single port you are connecting to only operates at a set speed; example of this is a USB 2.0 port operates at 480 Mbit/s. If you have a portable hard drive that runs at 300 Mbit/s and a digital camera running at 180 Mbit/s that leaves 0 Mbit/s left for any other USB device on the USB hub; you could run into a bottleneck

The TP-Link Archer C7 Router Review If you need a decent wireless router at a low price‚ the TP-Link Archer C7 (AC1750) model gets the job done. With the dual-band Gigabit (V2) design‚ you would think it is more expensive. Both the 2.4GHz and the 5GHz frequency bands are faster than the competitive brands out there. The Wi-Fi router has ample features with Gigabit LAN ports‚ USB 2.0 ports‚ management settings and more. The only gripe you may have is the web interface that is not as user-friendly

CHAPTER-1-INTRODUCTION 1. INTRODUCTION TO WIRELESS PC COMMUNICATION In many situations a communication link between two devices becomes essential. This communication can be wired or wireless. If two devices are close to each other a wired link is preferred. However in many situations two devices are reasonably far apart. In that case a wireless link is preferred. One of the popular wireless communication technologies is RF communication that is being used in our project. The HT12E and HT12D
