So from the topology we can say that the CAN differential signal is connected to CAN transceiver (MCP2551) which in turn is connected to CAN controller (MCP2515) with Tx and Rx pins accordingly, one for transmitting and one for receiving. These two can be placed in one board which must be connected to MC68HC11F1 development board. This connection is done using SPI (serial protocol interface) between CAN controller (MCP2515) and 68hc11 (Motorola microcontroller).Thus the development (MC68HC11F1)...
A private Network established within public network to lower the services provided by the big networks. Organization uses this to create wide area network (WANs) which covers a large region and provides connection to its branch offices and is users while others cannot access it. There are several confusing factor of discussion about VPN. It is because of the reason that various types of VPNs exist according to their constructions. The common types are:PPTP VPN (Dial up VPN):PPTP stands for...
Recently, various wireless communication technologies are being developed and used in many aspects of human life very closely. Many studies have been devoted by academic laboratories and industries. The third generation system, for example, is currently in general use, and next generation communication technology is a matter of primary concern. Despite of the bright future of the wireless communications, however, it may have many problems regarding the scarcity of frequency spectrum. New...
A simple network can consist on two computers by connecting them with each other. There are different mediums such as cable; air waves, fiber optics etc are used to send data from one machine to another. In a network as many computer can connected with the respect of need. In a network two machines or more than two machines can send or receive data from one end to other at same time. Many different devices are used to send make a quick and efficient network. A network can be established...

Front end web developers usually worry about the look and feel of their design interfaces since it is a major consideration by end users in their decision to use their product. As discussed in class, Shneiderman proposed eight golden rules of interface design. The first on his list is that the designer should strive for consistency. On www.ribbonsofred.com, consistency is strictly adhered to because of the use of consistent color, layout, capitalization, fonts, and icon placement throughout the...
The date and time for all computers running on a Windows Server 2008 network is synchronized by the Window Server 2008 Window Time service (W32time). In making it reliable and scalable time service for enterprise administrators, Network Time Protocol (NTP) and time providers is integrated in the service. The purpose of the Window Time service is to make sure that all computers running the Windows Operating System in an organization use a common time. The Window Time service uses a hierarchical...
Due to the increasing threat of attacks and malicious activities, the deployment of firewall technology is an important milestone toward securing networks of any complexity and size. Unfortunately, the inherent difficulties in designing and managing firewall policies within the modern highly distributed, dynamic and heterogeneous environments might greatly limit the effectiveness of firewall security. It is therefore desirable to automate as much of the firewall configuration process as...
Web servers are an integral part of a web application. Choosing the right web server that meets the application's requirements and the expected load is a key decision in providing a real-time response. This paper studies and compares the performance of different open source web servers like Apache Tomcat and Jetty under different loads. The objective is to carry out load testing using Jmeter, which is an open source tool, written in java. In the process, web service used in load testing is...
With the invention of IT, it did change the way people work other than the way people live. It helps people to save time and cost to produce even better work compared to working manually. Most of the works can be done with paperless in the electronic way. Other than that, it has the ability for people to produce mass production in a short time. "Electronic mail, groupware, telecommuting and videoconferencing, have become relatively standard technologies to enhance group processes. These...
