The lower four layers of TCP/IP define the same kinds of functions as the matching layer numbers from OSI. 11. c. The PCs use two wires to create a circuit to send data from PC1 to PC2. 12. A.The Ethernet header lists PC2’s MAC address so that PC2 will realize that the data is meant for PC2. 13. b. Packet 14. b.
2^128 = 340,282,366,920,938,463,463,374,607,431,768,211,456 4. Why do you think the world is running out of IPv4 addresses? The IPv4 address only allows only around 4.3 Billion addresses. There are currently more than 7 billion people in the world. While everyone doesn’t have a connection, there are more devices than people and servers to serve content.
Why was it created? Use your textbook and Internet research to support your answer. TCP/IP stands for Transmission Control Program(Protocol is the earlier version) and Internet Protocol. These two were created basically at the same time by 2 Darpa Scientists without one it would be hard to nearly impossible to have the other. This system was created because it was a way that any network could communicate with another through a gateway.
Alpha also sends 3,000 Web pages per hour at 40,000 bytes in size, equaling 50 emails per minute or 0.833 per second. This equates to 33,333.33 bytes per second or 266,666.64 bits per second. In total, the Alpha Corp is sending 269,990.64 bits per second between their emails and web pages. Today, 1,000 emails (75KB each) and 3,000 web pages (1,246KB each) per hour would equate to 8.16Mbps needed for the Alpha Corp.'s internet connection. 2.
The Class A networking address scheme is designed for the government and large institutions needing a great deal of unique nodes. Although the Class A network has only 254 unique network addresses, it can contain approximately 17 million unique nodes, which can make subnetting such a network a nightmare. Getting up to speed with subnetting Class A addresses requires a little forethought, some basic
The device also includes 3 years anti-virus and anti-SPAM protection for all devices connected to the network (Dell). The SonicWall has multiple ports that can be configured for external and internal connections. The recommended setup for your agency is a single port used for external WAN connection and two ports used for internal LAN connections. The two internal ports will be configured so that the wireless bridge to the satellite office is on a separate subnet from the main Austin office. Figure 2 of Section 1.4 shows the recommended subnet setup.
Each of servers will have 32 gigabytes of memory with dual Intel Xeon Processors. The server will have 12 1.2 terabyte hard discs and two dual-channel 10 Gbps network controllers. Each server will have dual-power supplies. One power supply will plug directly into a prime power generator and the other plugs into an APC power supply mounted inside the cage. Inside the cage a Cisco 6500 Series with a WS-X6816-10G-2TXL (Cisco Systems, 2012) fiber controller is needed.

Joshua Rose NT 1210 Lab 9.1-9.2 Lab 9.1 Broadband Internet Exercise 9.1.1 1. During the early days of the internet, the landline was also part of your internet connecting. If you was on the internet you could not use both at the same time, one would terminate the other. 2. Broadband use a signals over a wide range of frequencies in high capacity telecommunication.
To be able to show all 16 possible numbers 0-15 you can change the circuit so that the most significant bit (the eights place) is shown by an LED and the rest of the number is displayed on the MAN72, this would then be a successful binary to octal number system conversion circuit. Lab 4 – Logic Gates Materials: - 7400 quad 2-input NAND gate - 7402 quad 2-input NOR gate - Two 1.0 kΩ resistor Purpose: The purpose of this exercise was to set up a simple NAND or not and gate and a NOR, or not or, gate. Once set up, using one of the resistors to ground for a logic of one and a simple jump to ground for a logic of zero, the goal was to test the truth tables for these two gates. Procedure: The setup was incredibly simple, we simply set up and VCC’d the ICs and then began to test. The trouble came when our results were not matching the anticipated theoretical results.
