| Checkpoint Week 4 | | | Joseph Barnes | 11/3/2012 | | Wireless networks have become very popular in many households this is in part because it makes things convenient for the user. They physically do not have to sit in front of a computer to get access to it. I have a wireless network in my home and it is at times very useful. I have the freedom to move around and access the internet from anywhere in my home. I do not have to sit in front of my computer and use the computer

Wired or Wireless‚ What’s the Difference? The main difference between a wired and wireless data communication infrastructure is the existence of physical cabling. The same‚ or similar techniques are employed for both types of data communication infrastructure in terms of the core elements of essential network services. The basic difference between a wired and a wireless network is self-explanatory. A wired network uses wires to communicate whereas a wireless network uses radiowaves. Let us look

Someone gaining unauthorized access to my network is something I would try to prevent at all costs. Unfortunately‚ even the best security measures can be compromised which allows someone to cause unspeakable harm to the devices connected. Out of the list of potential security breaches‚ Script Kiddies would be the one that could cause less damage than anything else. These hackers are typically people who know little about computers and may have not used them for very long. The script-kiddies download

and pirating in the networks is very easy and it can lead to information damage or robbery and also if one compute is affected by a virus it can spread to the other easily. 3. What technology allows computer networks without wires? Wireless networking allows computer networks without wires. 4. Describe the difference between a LAN and a WAN. LAN is local area network‚ it consists of a group of networked computers that all located in one building. But WLAN is wide area network‚ it is a group of

Antenna Characterization for Wireless Power-Transmission System Using Near-Field Coupling Wireless power transmission is the transmission of electrical energy from a power source to an electrical load without man-made conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient‚ hazardous‚ or impossible. So a study was made on the investigation of wireless power transmission by near-field coupling from the view

INTRODUCTION In this paper of Wireless USB‚ I will try to give the uses of WUSB‚ its advantages‚ work area‚ features of using WUSB‚ etc. At the same time I will points out the application of using WUSB along with its specification. Universal Serial Bus (USB) is a serial bus standard to connect devices to a host computer. The USB 3.0 is the u version of the USB. The USB 3.0 is also called super speed USB because the USB 3.0 support a raw throughput of 500 MByte/s. In the new universal serialbus specification
