Open Systems Interconnection (Osi) Model Essay Example for Free

Open Systems Interconnection (Osi) Model Essay The two most recognized network reference models are: The Open Systems Interconnection (OSI) model †¢ The Department of Defense (DoD) model Without the framework that network models provide, all network hardware and software would have been proprietary. Organizations would have been locked into a single vendor’s equipment, and global networks like the Internet would have been impractical, if not impossible. Network models are organized into layers, with each layer representing a specific networking function. These functions are controlled by protocols, which are rules that govern end-to-end communication between devices. Protocols on one layer will interact with protocols on the layer above and below it, forming a protocol suite or stack. The TCP/IP suite is the most prevalent protocol suite, and is the foundation of the Internet. A network model is not a physical entity – there is no OSI device. Manufacturers do not always strictly adhere to a reference model’s blueprint, and thus not every protocol fits perfectly within a single layer. Some protocols can function across multiple layers. *** All original material copyright  © 2012 by Aaron Balchunas ([emailprotected] com), unless otherwise noted.

It provided the first framework governing how information should be sent across a network.

Racial Profiling by Police in Canada Essay -- systematic discrimination

Systemic discrimination has been a part of Canada’s past. Women, racial and ethnic minorities as well as First Nations people have all faced discrimination in Canada. Policies such as, Charter of Rights and Freedoms, provincial and federal Human Rights Codes, as well has various employment equity programs have been placed in Canada’s constitution to fight and address discrimination issues. Despite these key documents placed for universal rights and freedoms Aboriginal and other minority populations in Canada continue to be discriminated against. Many believe there is no discrimination in Canada, and suggest any lack of success of these groups is a result of personal decisions and not systemic discrimination. While others feel that the legislation and equality policies have yet resulted in an equal society for all minorities. Racism is immersed in Canadian society; this is clearly shown by stories of racial profiling in law enforcement. The key to understanding racialized profiling is to understand what systemic discrimination and profiling mean. Systemic discrimination sometimes called systemic racism is defined as, â€Å"Patterns and practices†¦ which, although they may not be intended to disadvantage any group, can have the effect of disadvantaging or permitting discrimination against†¦ racial minorities† (Comack, 2012, p30). Profiling in policing is defined as, â€Å"The inverse of law enforcement. In law enforcement, a crime is discovered and the police then look for a suspect who might possibly have committed it. Profiling means that a suspect is discovered and the police then look for a crime for the person to have possibly committed† (Tator & Henry, 2003, p3).

The company’s operations relate to manufacture of rubber products, such as tyres, of applications. MRF has six production facilities in India and around 80 sales offices. From its humble origins in 1946, the company has come a long way to become the market leader in the tyre manufacturing industry. MRF exports its products to over 75 countries worldwide. Today, global tyre manufacturers have to plan and adapt to changes in customer demand, fluctuations in raw material prices and availability, while keeping pace with timelines for shipments; in the face of increasing ompetition in the global marketplace. The Need for SAP Before becoming an SAP customer, MRF was running several outmoded legacy systems that could no longer keep up with the company’s expanding operations, and, as a result, the company was plagued with inefficiency. Problems of slow availability of information, tedious manual entry and data transfer, lack of system flexibility, excess manpower utilization and costs started to have a negative impact on the business. Consequently, the company was spending a lot of time in consolidating the information, getting the data together, and on time. It did not take long for MRF to know that it had to replace its nonintegrated, independent systems if it wanted to gain strategic insight and higher productivity to manage rapid business growth. The company wanted a flexible solution to allow IT to keep pace with changes while offering a low total cost of ownership. MRF decided to reengineer its entire IT landscape by implementing SAP ERP and SAP CRM solutions, based on the SAP NetWeaver platform. A Core Team called the Power Users team was formed to determine the requirements of the company and the selection of a suitable ERP olution. MRF brought in IBM Global to facilitate the process and the Core Team was sensitized to the process of reengineering. The company did a detailed evaluation based on various criteria such as experience in the manufacturing sector and product-offerings; Oracle and SAP were short listed. MRF participated in a SAP summit which helped the company to take the final decision. â€Å"SAP came out on top in terms of product superiority, post-sales support, and record customer satisfaction. We were confident that SAP will support our plans for continued growth,† says Prince Azariah, Chief Information Officer, MRF Limited. SAP offered a clear solution for MRFs manufacturing operations which include process as well as discrete production. â€Å"We have moved onto a mature product with SAP. We have made a very good decision in selecting SAP,† adds Sathya Gautham, Manager IT Services. Implementation MRF chose Siemens Information Systems as the implementation partner after a thorough selection process. The project went live on December 1, 2007. There were around 60 members from MRF and 35-40 members from Siemens involved in the implementation process. The core team nd the partner’s team worked in full collaboration, while ensuring that the implementation was carried out according to time schedules. â€Å"One of the complications was that our systems were in silos. Change management has been a big challenge,† says Gautham. There were many instances when MRF looked to SAP India and SAP Labs for assistance and support during the implementation. SAP ERP has been implemented at the company’s Head Office in Chennai, 6 factories in Sales Offices. MRF went in for all core modules including Financials and Controlling (FICO), Sales ; Distribution (SD), Materials Management (MM), Production Planning PP), Quality Management (QM), Plant Maintenance (PM), Human Resources (HR), and SAP NetWeaver Business Intelligence (SAP NetWeaver 81). Today, there are around 700 users who have accepted the implementation in a positive manner. Benefits With SAP ERP, the company has one harmonized, standardized and integrated solution. The solution has enabled MRF to transform its business operation management from time consuming and inflexible to real-time and adaptable. The users can now count on easy access to accurate, complete, and up-to-the minute information, thanks to entralized, integrated data. This has led to quicker decision making and improved business transactions for MRF. SAP is the best thing that has happened to MRF,† Sathya Gautham, Manager IT Services The implementation of SAP has brought in a major shift in the work-culture in the company. â€Å"The core team was clearly aware that they are responsible for creating their future. Earlier, we were a top-driven company. Now, we have close to 60 personnel at the middle management level who have been empowered to take business decisions, and who are advising top management on what needs to be done o set up processes in the company. There is so much of enthusiasm among the core team members and the end-users. Also, we used to be a very silo-ed company. With SAP, the Heads of different Departments look to these people for resolution of problems.

Performance management systems can provide a variety of benefits to companies which include clearly articulated strategic goals, valid evaluation data, and recognition of contributions made by the employees. It is essential for such benefits to be realized that a company maintains an on-going feedback cycle along with and fair and equitable pay. In a performance management practices survey, Bernthal, Sumlin, Davis, and Rogers (1997) found that the majority of CEOs surveyed, 63 percent, believed their performance management system drove the key factors associated with the business strategy. An even greater majority, approximately 79 percent, perceived their performance management system as driving the people or the cultural strategies that maximize human assets. This shows that there is a definite connection between theoretical viewpoints on performance management systems and the actual business practices used by various companies.
