When one computer wants to send data to another, it has to catch a free token which gives the permission to send data. As soon as one particular machine gets the token, it has the control over the whole network which means no other computer can send data. Then it puts its destination address and the data on the token, and sends the token to the machine that ¡s next to it. If the next machine is not the destination, it will pass the data on and on until it gets to the address. When the addressed station gets the data, it can not keep the message and release the token. It copies the data, then it sends the message back to the initiator with the acknowledgment to say that it has received the data. After the initiator receives the message and reads the acknowledgment, the free token can be released onto the ring. There are similarities and differences between Token Ring topology and Bus topology. In a Bus topology (Ethernet) all devices are connected to a central cable, called the bus or backbone.(ce.org/networkguide/netstructure/net4.asp) Ring topology is similar to Bus topology in that both networks have multiple access so that the messages will got to every station on the network. However, they are different. First, a Token Ring network has a ring which connects the network instead of a cable. Second, for Ethernet, when computers get messages which do not belong to them, they will not keep them and pass them on. Token Ring topology is different. Every machine on the network will keep passing on the data until it gets to its destination. Third, a computer on a Bus network has to wait for the network to be clear in order to send data packets. A Ring network has a token, so as soon as a machine ca ...

5 Steps on How to Get Organized in College

5 Steps on How to Get Organized in College With all that you have to balance, getting organized in college can sometimes seem like both a hopeless and useless task. After all, what kind of person can create order out of so much chaos?! You might be surprised, however, to learn just how easy it can be to get organized during your time in school. 1. First and Foremost, Have a Time Management System Whether youre a super senior or an incoming first-year student, time will be your most precious commodity. Just when you need it the most, it will seem the most scarce. And you will rarely if ever, feel like you have enough of it. Consequently, having a good time management system that you use is critical for getting organized - and staying that way - during your time in school. After all, how are you supposed to know what youre supposed to be doing if you arent even sure, well, what youre supposed to be doing? 2. Write Down All Your Academic Responsibilities When you first get your syllabi at the beginning of the semester, find a quiet table at a coffee shop, get a cup of coffee, and sit down with your calendar. Put everything thats on your syllabi into the calendar: when classes meet, when things like required films and labs are scheduled, when midterms are, when classes are canceled, when finals and papers are due. And when you think youre all done putting everything in, double check your work and do it again. Once you have everything inputted into your time management system, you can rest assured that youll know about all required course assignments well before their deadline. Sometimes, just knowing whats coming down the pipeline can account for 90% of your organization prowess. 3. Go Through Something Once a Week It sounds strange, but youll likely be surprised at just how helpful this rule can be when it comes to staying organized in college. At least once a week, go through and organize something. It can be your backpack; it can be your bank statement; it can be your desk; it can be your email. You undoubtedly, however, will find something that slipped your mind or that youve been meaning to get to. And if you hadnt have gone through that item, you would likely have forgotten all about it. 4. Have a Budget and Check in on It Regularly A major part of being organized in college is staying on top of your finances. Even if most of your costs, like room and board in the residence halls, are taken care of through the financial aid office, staying on top of your money situation is still important. Being organized means knowing whats going on in your college life at any given point in time. If you arent sure how much money is in your account - or, worse, if youll have enough to make it through the semester or quarter - you arent organized. So stay on top of your budget and know where youre money has gone, where it is, and where its headed. 5. Be Proactive and Plan in Advance You know that guy down the hall who always is stressing out and cramming last minute for exams? Or that girl who freaks out every time she has a paper due the next day? Chances are youd be hard pressed to find someone who would describe either of them as organized. If you know whats coming - holidays, major events, midterms, papers, lab reports, finals - you can plan in advance and avoid unnecessary chaos. And if you know whats coming, you can organize your life (e.g., get enough sleep) far enough in advance that you can still enjoy yourself during even the worst of the worst.
