Pg 60 - 3.1 Lab 3.1 review 2. 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. Back in the late 1970's, two projects began independently with the same goal in mind, which was to define a unifying standard for the architecture of networking.
What is the history of the OSI reference model? How did it come about and why was it created? Answer: OSI is an open system on based on a seven layer model. This model was created by Charles Bachman. The basics of this system is it is layer btween other layers of networking.
Research Assignment Part 1 Part 1: In this first section, you will investigate the changes made to the architecture of Windows Server 2008. Research from the ITT Tech Virtual Library and the Internet to answer the following questions: 1. Why Windows Server 2008 comes in different versions? What is the significance of each version? 2.
A COMPILER is a program that translates a high-level language program into a separate machine language program. An INTERPRETER is a program that both translates and executes the instructions in a high-level language program What type of software controls the internal operations of the computer’s hardware? An operating system controls the internal operations of the computer’s hardware Unit 1 Research Assignment 1 Algol (ALGOrithmic Language): 1960, Defined by an international consortium. Algol was the first language to be machine independence. It has many of the common language features, such as If-Then-Else, For and While loops, Switch with gotos, begin and end markers, local variables, etc.
Norman Jones-ITT Tech Institute Integrated Distributors Incorporated: Access Control Proposal Vulnerability Scan Report IS404: Access Control, Authentication and Public Key Infrastructure (PKI) V 1.0 December 29, 2015 Course Professor: Helio De Castro Introduction General Summary Integrated Distributors Inc. (IDI) is a multinational organization with offices in several countries. Each organization’s location operates with different information technologies and infrastructure-IT systems, applications and databases, each utilizing various levels of IT security and access management within their respective locations. IT Architect’s Access Control Proposal * Develop a plan to improve IDI’s Computer network using a multi-layered security
OSI Model: Open System Interconnection * Is a conceptual model that characterizes and standardizes the internal functions of a communication system by partitioning it into abstraction layers 7) Application Layer | 6) Presentation Layer | 5) Session Layer | 4) Transport Layer | 3) Network Layer | 2) Data Link Layer | 1) Physical Layer | * The model group’s communication functions into seven logical layers. A layer serves the layer above it and is served by the layer below it. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer. (Wikipedia) 2.
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.
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.
The following organizations will be discussed that handle the transfer of data, ISO, ASC X12N, ASTM, HL7, NCPDP. Protocols Used The OSI has seven layers of protocols, they are application, presentation, session, transport, network, data link, and physical. Application allows communication in a number of different ways. Some of the ways that Application layer allows communication is through file transfers through “e-mail and other network software like Telenet and FTP” (Softpanorama, 2014). The presentation layer “provides independence from
What it is responsible for is the synchronizing frames, error checking, and the flow control. The third layer of the seven layers of (OSI) network model is the Network layer. The responsibility of the Network layer is managing the logical address information in packets and the delivery. The responsibility in managing logical addressing information and make sure that it is correctly sent to the right destination. The direct data packet generated by Network Layer using information that is stored in a table known as routing table.
