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

1. An enterprise campus LAN uses wired UTP Ethernet and wireless 802.11 LANs at the edge of the LAN. Looking at a particular floor in a particular building‚ all the devices connect to either a single Ethernet switch or single wireless access point‚ both of which sit in a wiring closet in the middle of the space. Which of the following is true about the distance limitations in this LAN? C. All Ethernet user devices can be up to 100 meters away (but no farther)‚ while WLAN devices must typically be

determined by colorimetric titration‚ and the identity of an unknown acid was determined by potentiometric titration. In the first titration‚ a strong acid standard‚ potassium hydrogen phthalate (KHP)‚ was used‚ to determine the concentration of a strong base‚ sodium hydroxide (NaOH). In order to do so‚ we prepared NaOH solution‚ prepared a buret‚ and standardized this solution by performing a colorimetric titration of the KHP with the solution until a color change was present. The color change was introduced

INTRODUCTION The market for wireless communications has experienced incredible growth over recent years and wireless LANs have rapidly become a very important network architecture offering benefits of increased flexibility and mobility. Unlike a traditional wired LAN‚ users can access servers with much greater freedom. Mobility in IP architecture as well as mobility between wireless LANs and wireless WANs enhances these benefits even

Base Details Siegfried Sassoon’s epic war poem "Base Details" focuses on a soldier’s bitterness toward the fact that old men wage war while young men fight it. Sassoon uses various literary devices to express his anger toward such injustice. The main ones being rhyme‚ strong connotative words and especially diction. The speaker‚ a soldier in World War I‚ contemplates what it would be like to be an officer in during war. By using a sarcastic and cynical tone‚ he is effectively able to condemn war

Chapter 6 ERIC PAUL MARTINEZ NT1210 10/31/13 Wireless LANs This chapter will allow you to explore the concepts of modern wireless networking. Though there are other wireless technologies such as infrared communication‚ this chapter focuses on wireless standards and technologies for radio frequency– based communication. The IEEE 802.11 set of standards defines this type of communication and interactivity among these devices. In this chapter‚ you will use the wireless Cisco routers
