IT 205 Week 4 Check Point: Monitoring Employees on Networks Employers want to limit an employee’s use of e mails or internet usage during work hours for the following reasons; employee productivity‚ and network safety. If an employee is using e mail or the internet for his or her own personal use rather than business use‚ it is costing the company the loss of potential revenue. The amount of traffic on a company’s network could risk the network’s safety and also cause the server to become clogged

Outline the three general network topologies (bus‚ ring‚ and star). Describe the components‚ devices‚ and arrangement of components and devices involved in each topology‚ as well as some of the pros and cons of each configuration. A bus network topology has the set up in which all the devices are connected by a common shared cable called the bus. The bus architecture has several common instances which include the one in the motherboard‚ (of most computers) and some with the versions of the Ethernet

Abstract Software defined networking is a new concept that redefined the current network device architecture and the way they behave. Due to the exponential growth of the Internet and services attached to this worldwide infrastructure‚ a number of issues have cropped up in modern day networks. This paper discusses a few of these limitations and how the software defined networking approach tries to alleviate them. OpenFlow‚ released in the year 2008‚ is a commercially viable implementation of this

Alternative Energy Sources Fossil fuels will not last forever. If the human race wishes to continue to live the way we do‚ then we have to look at alternative energy sources such as: geothermal‚ nuclear‚ solar‚ wind‚ and hydroelectric energy. Alternative energy sources are not without faults‚ but along with faults‚ there are benefits and solutions to the issues. Geothermal energy is a well-proven energy resource that can be used to provide both heat and electricity. Geothermal energy is very

Open/Closed Source POS 355 Open/Closed Source Product distribution probably seems very simple to the general public. Most people probably believe that it is simply how the product enters the end user’s hands. This is true‚ but with software distribution there are a couple different methods that the average person probably doesn’t know about. Open and closed source are the two ways in which software is distributed. They both have their advantages and disadvantages‚ but when it comes to operating

term for the physical components that make up a computer system. Software is a general term for the programs that control the computer system. Systems software are programs that allow the hardware to run properly‚ e.g. operating systems. Applications software are programs that allow the user to do specific tasks‚ e.g. spreadsheets. The central processing unit (CPU) interprets and executes the commands from the hardware and software‚ it used to be made up of numerous small integrated circuits. Microprocessor

Shirley van Dijk CIS 100 Open source Software paper What is open source software? Open source software is software that can be used‚ changed‚ and improved and moved freely. It is released under OSI which stands for Open source initiative. When people think about open source software we think about the software the free trials that are done after 30 days and then you have to pay for it. But this is not what open source software means. Open source software refers to programs where the code
