Bonus questions from lab work:
4 Byte – 8 bits
84 Essentially, link refers to any cable between two devices, and node refers to any device.
77 HTTP, the Hypertext Transfer Protocol, defines the rules by which a web browser can ask for a web page from a web server, and the rules a web server uses to send the web page back to the web browser.

231 Transmit on Pins 1, 2 | Receive on Pins 3, 6 – UTP unshielded twisted pair
258 To truly answer the question of the range for a particular WLAN, the network engineer needs to do some testing called a wireless site survey (site survey). The theoretical answer to the question of coverage area depends on many factors. A site survey bypasses some of the theory and simply tests to find out where the WLAN works and where it does not.
267 The Wi-Fi Alliance works to make the wireless LAN industry a success. *group of vendors*
278 In WLANs, both the coverage area and speed depend on a variety of factors as well. If no other factors change, the farther a device moves away from the AP, the more likely the device will have to send at a slower rate. *20 feet, 70 feet, 150 feet all have access but 802.11g*
315 Dedicated circuit: A leased line. A circuit between two specific devices that telco never takes down. *24/7/365*
318 Routers focus on forwarding IP packets to the right destination. IP, a Layer 3 protocol as compared to the OSI model, defines a header, with a source and destination IP address.
329 Customer responsibility – Smart Jack RJ-48 Socket | Demarc | Smart Jack – Telco Responsibility
357 Fiber Optics in the WAN, SONET defined a series of Layer 1 standards for much faster speeds using optical cabling. *pure digital technology: WAN Links*
377 First and foremost, an IP address acts as a number to uniquely identify a host inside a TCP/IP network. Every device that wants to communicate inside a TCP/IP network must have an IP address, and the devices use that IP address when sending and receiving IP packets.
381 Dynamic routing protocol – The purpose of the routing protocol application is to talk to other routers to learn routing information from each other. *route network packets more efficiently*
391 First Octet: 128-191, Class: B
372 DHCP – Used by a host to dynamically learn an IP address (and other information) it can use.
377 First and foremost, an IP address acts as a number to uniquely identify a host inside a TCP/IP network. Every device that wants to communicate inside a TCP/IP network must have an IP address, and the devices use that IP address when sending and receiving IP packets. *and groups of hosts*
379 IP hosts play a small role with IP routing. When sending an IP packet, the host thinks about whether the destination address of the IP packet is on the same LAN as the sending host. IF it is on the same LAN, the sender just sends the packet directly to the other host. If not, the sending host sends the IP packet to a router connected to the local LAN and lets the router deal with the question of where to send the IP packet next.
436 The term Internet edge refers to the part of the Internet topology between an ISP and the ISP customer.
438 Enterprises use many security measures and devices to make the...
