DEMARC What is SONET WAN technology? One of several key technologies often found in a WAN. SONET - Synchronous Optical Network is an international standard for high speed communication over fiber-optic networks. The SONET establishes Optical Carrier (0C) levels from 51.8 Mbps to 10 Gbps (0C-192) or even higher. SONET provides high speed connectivity over the network and is standard for physical cable.
a. Broadband b. Modem c. ISDN d. DSL 8. To connect a LAN to the Internet, you must use __________. a. a hub b. a switch c. a router d. an Internet cable 9. Which TCP/IP protocol is specifically used for transferring
These are defined as an operator of multiple cable television systems.This usually refers to large cable companies that provide service for multiple communities, such as Time Warner Cable, ComCast or Cox Cable and similar companies. These MSOs provide television service, broadband internet services, and telephone services. ISP stands for internet service provider. This is any company that provides customers direct access to the internet. They use copper cable, wireless, or fiber optic cable to give access to the internet for their customers.

Prepare a report (one paragraph) on the status of 3G and 4G service based on your findings. Answer 3G network is very advanced smart phone which has a variety of functions such as web browsing, instant messaging, access to emails, it give you option and allows you to download music, these functions are also similar to the functions of the 4G. The difference between the two are that the 3g speeds can usually reach up around 3 mbps wheres as the 4g has an average speed around
they use an ip address instead of analog signals. Most people would instantly assume it is voice communications but in fact it is data communications mainly because it sends voice fragments over the internet via TCP/IP, hence the name voice over IP. Skype / Facetime: Skype and Facetime have allowed us to not only speak but also see people over the internet. These amazing things use both voice communications and data communications much like voIP does. Data sends these voice and video fragments over the
a) The potential technological solution: Digital Subscriber Lines as a technology solution. b) Its use: Broadband internet connectivity over telecommunications copper from the telephone provider. c) Its application to the given scenario: Northeastern Health Services, Inc. locations are within reach of telephone provider wiring, which makes them a candidate for Digital Subscriber Line (DSL) connectivity. DSL is provided by telecommunications providers over cooper and works seamlessly with other telephony services including voice communications. However, DSL does have a limitation on transmission distance, which
a,b 8. Which of the following answers best describes the definition of a cabling pinout? a 9. A PC NIC connects to a switch port using 100BASE-T. Which of the following is true about what happens on that link?
Some of the things that NCP does include file access, printer access, security. Using TCP/IP (transfer control protocol) which is also on layer three and four of the model, and it allows a network to communicate through ort 80 or also known as HTTP (Hypertext Transfer Protocol. These protocols would be chosen based on the security, and the devices it needs to access the internet. In anything to do with networks and computers security is always number one so putting a WPA2 enterprise with a wireless router, in place would be very beneficial for Kudler so the router and the network can have a passcode in place so there will be no outside influences to hack the system. The authentication of the Radius server will be used for the WPA Enterprise which the router uses is 802.
Unit 7 Assignment Christopher Place Kaplan Online University Unit 7 Assignment Question 1 A Media Access Control Address (MAC Address) is also known as a physical address and is used on the media access control protocol sublayer and is assigned to routers ports to identify them to a physical address. The reason for the router having more than one MAC address is because it has two different ports assigned for different reasons and in this case it is for internet and LAN. An IP address is an address associated with every device on a network and a computer so that the internet knows where the web servers and mail servers can send their data to. The reason for the two different IP addresses on the router is because every router has two of them one is called the WAN interface or public IP address and the other is called LAN interface or private IP address. The WAN interface is the side that is connected to the internet which is why it is public and the LAN interface is the side that is connected to the network and that is why it is private.
