What is the history of the OSI reference model? How did it come about and why was it created? Use your textbook and Internet research to support your answer. Two projects began in the late 1970’s that was geared to a project that led to expanding the architecture of networking systems. One was the ISO(International Organization for Standardization) and the other was International Telegraph and Telephone Consultative Committee.
What is the history of the TCP/ IP model? Why was it created? Use your textbook and Internet research to support your answer. TCP/IP originated out of the investigative research into networking protocols that the US Department of Defense (DoD) initiated in 1969. In 1968, the DoD Advanced Research Projects Agency (ARPA) began researching the network technology that is called packet switching.

110 (network ID), 10.10.1 (host) What are the binary values of the host ID and the network ID? Hint: You should use decimal-to- binary conversion skills on each octet of the address separately and chain the bytes together for the answer. 1101110.00001010.00001010.00000001 Exercise 8.1.2 Use your textbook and the Internet to complete Table 8- 1. Class | Range of 1st byte (octet) in decimal | Network ID | Host ID | Possible Networks | Possible Hosts per Network | A | 0-127 | A | b,c,d | 2^7 | 2^24 | B | 128-191 | a,b | c,d | 2^14 | 2^16 | C | 192-223 | a,b,c | D | 2^21 | 2^8 | Why is the number of possible networks for each class not equal to 2 raised to the power of the number of bits used for the network ID? It would require more bits Exercise 8.1.3 Would the IP address in Figure 8- 1 be valid as a class C address?
In which she added widespread notes of her own. She included step sequenced of operations for solving certain math problems. She referred it to; “The First Programmer.” In addition, she assumed that the machine could go much further beyond the numbers and symbols if it followed the rules. Ada has been referred to as the “prophet of the computer age.” Therefore, I suppose you would state that Ada and Charles were the “first language,” in programming; additionally they would be the creator of the very first language for programming. In the 70’s the creator of the first language in that era was Niklaus Wirth.

| 17. Take a screen shot of the Group Policy Management console displaying all of the policy settings you configured in this exercise by pressing Alt+Prt Scr and then paste the resulting image into the Lab 8 worksheet file in the page provided by pressing Ctrl+V. Exercise 7.2 | Testing Internet Explorer Policies | Overview | In this exercise, you will confirm the Internet Explorer settings that are configured with a GPO are deployed to a client computer. | Mindset | When troubleshooting problems, you will need to ensure that settings that you configure with a GPO are actually deployed to the clients. |
TCP is the transport layer protocol that links the application layer to the network layer. TCP breaks the data into smaller packets, numbers the packets, ensures each packet is reliably delivered, and puts the packets in the proper order at the destination. IP is the network layer protocol and performs addressing and routing. IP software is used at each of the computers through which the message passes through; IP routes the message to the final destination. TCP/IP is the transport & network layer protocol used on the Internet.
