Writing An Effective College Essay

Writing An Effective College EssaySample college essays are a great way to get started writing your own. You may have learned that it is best to write your own essays, and that you should keep it short. The length of the essay, however, is not important. If you want to write an essay that is effective, then you will need to stick to its structure and try to build on it throughout the entire paper.Students should start by considering what types of college essays they are going to write. There are many different types of essays, that a student can write. Some examples of these types of essays include:All of these can be used as an introduction to a more detailed topic in any field of study, but this does not mean that they all should be treated as the same. In fact, many students will find that they do not like writing one type of essay and another type of essay. This is why it is so important for students to write many different types of essays.It is also a good idea for students to s tart with different types of essays. They will be able to see what kind of writing style works best for them. It is best to find some type of writing a guide that can help them. If they don't already have one, they should find one online.It is also a good idea to compare different types of essays before actually writing the actual essay. This is because there are times when students do not always understand what their assignment is. They should try to look over their assignment and see if there is something that they do not understand. Once they know what they should write, they should try to remember what they wrote in order to avoid repeating words or thoughts.As soon as a student has the instructions and materials, they should write the paper. This should be done as soon as possible after receiving the instructions and supplies. In order to make sure that the paper is going to be properly prepared, it is best to write the essay at least two times. Each time, the student should re vise their paper until it is perfect.When students begin writing, they should not try to rush through the assignment. This could put the student at a disadvantage, and cause them to create less-than-perfect papers. They should be able to take their time to write the paper in order to make sure that they are following the instructions completely. Any mistakes should be corrected immediately, and the corrections should be written down so that they can be tracked.After they have completed their essay, they should consider what to do next. They should try to communicate their idea with words, and they should be able to write a paper that has a beginning, middle, and end. These are all important steps in learning how to write a successful college essay. Once they learn how to do this, they will find that they can write their own essay without having to worry about their education or career.

We always say ‘we are the future’. Indeed. We, the younger generation represents modern knowledge, new concepts, ambition and great desire for success. But, have you ever thought of this question: how can we be successful in the 21st century, which is full of great challenges and fierce competitions? In my opinion, there are two important factors. First, we have to catch the opportunities and face the challenges. China has successfully entered the World Trade Organization, Beijing has won the bid for the 2008 Olympic Games†¦ If we want to be successful, we have to seize these opportunities. SARS and AIDS, environmental pollution, growing population†¦ We have no choice but to solve these problems with our own hands. Thus, catching the opportunities and trying our best to cope with the difficulties is necessary for us to succeed in the 21st century. ? Secondly, we have to learn to cooperate and compete.

Michael Lemonick's Are We Losing Our Edge Essay

Michael Lemonick's Are We Losing Our Edge - Essay Example Thus, through such competition, any country that has even a little bit of ambition and grit is being able to establish itself within the rest of the world as a global superpower in terms of its trade and economy. As per the words of Shirley Ann Jackson, America is thus facing what is called, a ‘Quiet Crisis.’ (Lemonick, Michael D.) Various kinds of aspects have together helped to stem the kind of growth that American was having in the last few decades, and compared to the current levels of growth, how the same has slowed down due to processes within the government framework and structure. For example, the author writes that during the period of George W Bush, a large amount of hostility was shown towards various topics under science, which were not given ample grants or potential for research and testing. This has further led to the growth of the meltdown that the country is facing on a global scale today. (Msurjapu) The inadequacies of growth going in America have been further highlighted by the kind of slow down that has been brought about in the corporate sector as well. These industries are not being given enough government support unlike other companies around the world in other countries are receiving; furthermore, they are cutting back on their investments and production for fear of going into losses and not being able to cover their initial and variable costs. According to personal opinion, the reign under Barack Obama has done far better in trying to perfect this global meltdown that America has been going through since the time of Bush. During his time, not much emphasis was given to various sectors that were at that time waiting to explode into fully potential fields of growth and development. Since areas like nanotechnology, supercomputing and alternative energy were not given as much importance in America at the time, other countries like India and Japan were trying their best to exploit these areas and emerge as victorious superpowers in the same. The final result was that these other countries had been successful in their operations and left America a step behind in terms of such development in the fields of science and technology. By the time it was time for Bush to step down and Obama to take control and fix these factors, other countries around the world had established their own levels of competition in the global market with respect to these full of potential growth aspects of life. That is why, America has been said to be losing out on its edge; the same edge that it held over the global market earlier, due to such intolerance towards research in newer fields. This has been taken up by other nations around the world now, leading to American being put into the competition at the same level, and not a cut above the rest; a position that the country used to maintain in the past. Lemonick has made use of a number of rhetorical strategies to write his article. These are strategies used in order to make the wri ting more powerful and persuasive for the reader, and help him understand a person’s point of view better. However, each piece and kind of writing requires a different kind of strategy to be used, and not all of them can be used within the same article. Lemonick has made excellent use of exemplification within his article. This includes providing facts and

Basic Network Technology, Structure, and Protocols Essay

Basic Network Technology, Structure, and Protocols - Essay Example This is not excusable in the 21st century hence looking at the basic or fundamental things that an individual should know is imperative. Computer networks have been used in sharing resources and data as well as for communication purposes. In order for one to have optimized performance, maintenance, data protection, security and improved reliability knowing the basics of the computer networks is of utmost importance. This paper outlines most of the things that a computer user needs to know. Computer networks security For any computer network, security is of utmost importance. Computer networks are always vulnerable to a number of security related threats which could be either external or internal. These include spyware, viruses, Trojan horses, web worms, hackers, adware, intruders and root kits. These security threats have a number of negative threats. Some of them impair certain computer applications and programs while others may modify, delete or corrupt files thereby making them in accessible. They may also attack the data that you have in the hard disk causing it to crash hence necessitating reformatting. While some may not necessarily harm the system’s integrity, they will always consume the system memory thereby slowing it down significantly. In some cases, you have computer malware which reinstalls itself in the computer system even when you have uninstalled them. Evidently, computer malware would have adverse effects on the computer networks. In this case, it is always important that an individual has a clear understanding as to the ways in which the computer security could be supplemented. There are several ways in which this could be done; they include installation of antivirus software, regularly updating the anti-malware programs and having the whole system scanned. Knowing about the security of the computer networks allows individuals to keep their data and resources protected. In addition, they would keep their systems functioning in an optim um manner in which case maximization of output from the computer network will be the direct result. While there may not be a standard way of teaching individuals about the security aspect of the computer networks, I think that the best way to tech people about hem is to outline the threats posed to computer networks, the effects and the best way to safeguard the network against such threats. Computer networks connectivity issues As stated earlier, computer networking is all about communication and sharing of data and other resources. This would only be accomplished when there is the appropriate connectivity. However, many are times when the connectivity of a computer network is impeded by varied factors. Connectivity problems emanate from faulty hardware, devices conflicts, improper configurations, faulty connectors or cables and even outdated drivers of the LAN card. This would call for troubleshooting by scanning the computer for spyware or viruses, checking the LAN card configura tions and updating its drivers, properly inserting the STP/UTP cable or even replacing the LAN card then reconfiguring it. Software troubleshooting issues For any computer system, software plays a very vital role in the whole operation process. Right from the operating system to the drivers, software and programs, their importance cannot be understated. This underlines the fact that when they are not operating in the appropriate manner, the whole system

Self-healing Operating Systems Essay Example for Free

Self-healing Operating Systems Essay The dependability of computer systems is one of the key issues in the technological era. Our daily lives are currently governed by complex computer systems (Haugk, Lax, Royer and Williams, 1985). Operating systems capable of managing key application on computer systems should be in a position to cope with the increasing rate of software problems, malicious attacks and hardware flaws (Parhami, 2005 and Lohr, 2001). One of the most significant requirements for operating systems is resilience to errors. Most of the operating systems stop operating once they encounter a problem with the hardware or software. This results to loss of applications and data running in the system. Some common examples of such issues are Windows blue screen errors and kernel panics in UNIX (David and Campbell, n. d). This is unfortunate since the main concern of the users is with the applications and data. They are afraid of losing data out of a fault that it not of their making. Even after a fault is encountered in the software or hardware, the users would want to have their data intact and recoverable. This problem has been taken care of by the invention of Self-healing operating systems. Self-healing operating systems refer to systems that automatically detect, diagnose and repair software and hardware problems that are localized. There are various techniques that are used by the operating system in recovery, once an error has been detected (Andrzejak, Geihs, Shehory and Wilkes, 2009). Code reloading Temporary memory errors or memory corruption as a result of an erroneous code can lead to errors like illogical instructions to the software code. Despite the fact that the ECC memory is capable of detecting and fixing some temporary memory faults, it is not capable of handling corruption faults that result from invalid instructions. The simplest most effective technique to handle such a problem is code reloading. This recovery technique reloads the flawed memory work from permanent memory. In case the fault is permanent, a case that can be identified through testing, there is a possibility of recovering through remapping of the faulty hardware page utilizing virtual memory support. In case the processing unit points to an undefined command exception, the command is reloaded by the handler from a copy of the system code in memory-mapped permanent memory and the command that is reloaded is executed. This recovery procedure is the simplest in implementation. However; the procedure is not capable of detecting memory corruption resulting from an opcode transforming into another legal opcode (David and Campbell, n. d). Regular checking of the operating system code is important to better detection of flaws in the memory. Hashing and checksums are simple methods of verifying of running system code. If a fault is detected a reload is triggered very fast. This is a preventive strategy that is capable of detecting flaws before they cause errors. The preventive strategy is also capable of detecting faults that make an opcode to result to another legitimate opcode (Demsky, and Rinard, 2002). CRC-32 checksum of critical kernel code is computed periodically by choices. This is makes sure that the memory where the instruction is stored has not been corrupted. In case the checksum changes as a result of corrupted memory, the block of the memory that is corrupted is reloaded from the permanent memory. Flushing of the instruction cache is carried out to ensure that all the affected commands are disposed of. The checksum can also be computed as soon as an operating system error is detected. This is done to make sure that the system and recovery code is not affected (Liedtke, 1995). Modern ARM-based processor designs consist of Run Time Integrity Checker (RTIC) hardware. This hardware is capable of being configured by the operating system for computation and verification of SHA-1 hashes of specific code areas. Once an error is identified, a communication is made to the processor via an interrupt. The same kind of checksum verification can be utilized in checking the integrity of fixed data. Checking the integrity of changing data is hard. One weakness of this recovery procedure is that it cannot be clearly used for codes that are created at run-time or for self-modifying code. This means that care must be taken to make sure that a replica of the created code is stored in a permanent memory (Shapiro, 2004). Component micro-rebooting This technique has been proven to be effective for application programs. Application of this technique to OS is also practicable (Voas and McGraw, 1998). The technique can help in recovery from temporary hardware flaws and some system bugs. For the Nooks project, this technique as extension restarts was utilized for recovery of the Linux Kernel. The technique involves reinitialising the corrupted part or destroying and recreating it and then re-requesting the component. While in code reloading errors are fixed only in processor commands, in this technique errors are fixed in kernel data structures. The technique works in collaboration with isolated components. The wrapper elements that offer isolation of the components are also utilised in the management of the recovery. The fault model that is addressed in micro-reboot is component-level flaw repression. This can be partly implemented by component isolation (Tanenbaum, Herder and Bos, 2006). Automatic service restarts In case crucial operating system service, like the paging daemon, stops working, it brings the entire system to a stop. Once the failure of such a crucial process is realised, a restart of the process can solve the problem and continue the operation of the operating system. The flaw model that is handled by automatic service restart is single-process failure. In this case there is usually no external state corruption. In micro-kernel OS, this basically involves detection and restarting of the affected system services that are run as application processes (David, Carlyle and Campbell, 2007). For instance, in Minix3, this operation is carried out by reincarnation server. A system process could be developed such that it is mechanically restarted once it encounters an exception. There is a particular system process that loops constantly awaiting a prepared process and acquiesces to the new process. This special system process is the process dispatcher. The system becomes completely useless once the process dispatcher crashes. This is the reason why in some systems the system dispatcher is executed as a restartable process that can be recovered once it crashes (Demsky and Rinard, n. d). Process restarts may fail to work where the process utilizes locks for accessing shared data structures. Such cases are common where the process dies while holding a single or more locks. Even in case the shared data structures are not affected or they can be corrected, recovery will not happen unless there is releasing of all the locks held by processes. This is why the system should be such that it can track all the locks help by processes and forcefully release any that is help once a process is halted. It is possible to implement lock tracking and force unlocking to ensure that the process runs once a fault has been identified and fixed (Tanenbaum, Herder and Bos, 2006). Watch-dog based recovery This technique utilises external hardware watchdog timers. They are utilised in error detection where the operating system is not doing any useful work. This is such a case where the OS is in an infinite loop. There is need for regular resetting of the timer by the operating systems. A signal is sent to the processor once the timer expires. The processor has a reset pin where the timers are usually cabled. They lead to a complete reboot of the system in case of failure. This process has a weakness for a complete reboot results to the loss of user data and applications that are currently in the volatile memory. However, since the memory is conserved after a process reset, reconstruction of both the operating systems and user state is possible. This makes it possible to continue operating after the reset. This way the user data is recovered resulting to higher reliability (Andrzejak, Geihs, Shehory and Wilkes, 2009). This technique has been successfully implemented in Linux and Choices. Once there is resetting of the memory management unit (MMU), interrupt subsystem, watchdog bites, and the processor, the system continues to operate effectively. To be able to avoid loosing the user data, the reset handler passes the usual boot procedure when the reset is instigated by the timer. The reset handler turns the memory management unit back on, there is deactivation of the running processes, reinitialising of the interrupts and skips to the OS’s process dispatch loop. After this the system runs the next ready process (Shapiro, 2004). All that is lost is the process state of the one that was running during the resetting of the processor. The process whose state is lost cannot be scheduled once more. As a result, it is eliminated from the process queue. A solution to the lock-up state is delivering of exception to the thread that is locked up. In this case, the thread is free to try local recovery rather than being forced to terminate. Watch-dog based recovery uses single process crash as a fault model without external state corruption. The technique utilises the lock tracking code in the release of pooled resources that are in a process that is terminated. Another kind of lockup that can initiate a watchdog timeout is a deadlock. Recovery in this case can be tried by restarting some parts so as to break cycles (Andrzejak, Geihs, Shehory and Wilkes, 2009). Transactional roll-back Once an error results to an exception during an operation, there could be a roll back of the state of the part. This can be achieved through the abortion of the operation. After abortion, the operation is then retried. In Choices, management of a transaction is carried out by the same wrapper elements that offer isolation. The transaction is aborted by the wrapper. Where there is unhandled exception, the state of the part is rolled back. It is also possible to use multi-threaded and non-blocking execution offered by RSTM for better performance (Brown and Patterson, 2001). Support of transactional model on parts results to expenses in terms of space and time. Expenses in terms of space are as a result of storage of backup copies of states prior to transactions. In terms of time, it is due to performance of memory copies and management of the memory during the set up and committing of a transaction (Marathe et al. 2006). Transactional roll-back differ from component micro-booting since the roll back is only on the current process, while the latter re-initialises the entire internal state of the process. Based on the kind of the component, either of the two techniques can be employed. Particularly, in case the component has crucial state information that can be lost if component micro-booting is used, then transactional roll-back can be utilised to retain the state. Component micro-booting is useful when the component can withstand state reinitialisation and has few overheads (Demsky and Rinard, n. d). Process-level recovery Where clear recovery cannot work, or in case the recovery process becomes erroneous, specific process states can be stored to permanent memory. This is carried out as the last option is all the others cannot work. Once the user states are stored, the system can attempt full reboot. The state of the processes can then be saved selectively into the computer. Every operating system state is reinitialised after the reboot probably removing fleeting errors. Process-level recovery ensures that user applications are not lost when the fault affects only a few system applications or immaterial operating system state. The technique can be used in collaboration with file system snapshots to make sure that the file integrity is not affected after the recovery process by going on to run erroneous processes. This procedure needs minimal support from the operating system. All it requires is an operational permanent memory drive and user process state management code. The stored processes can be restored selectively after the healing process (Ghosha, Sharman, Rao and Upadhyaya, 2007). Conclusion The reliability of computer systems is one of the key issues in the modern society. This is because computers have become central to our lives and we depend on them for many of our operations. A reliable computer system is one that can recover from a fault or an error effectively and without loss of either user applications or data. This is the reason why operating systems have been developed such that they are self-healing. This means that they can automatically detect, diagnose and repair software and hardware problems that are localized. The recovery techniques discussed on the paper include: Code reloading; Component micro-rebooting; Automatic service restarts; Watch-dog based recovery; Transactional roll-back; and Process-level recovery.

The Man in the Black Suit :: Personal Narrative Death Dying Essays

The Man in the Black Suit We gathered together in our plain, small-town church for the funeral of my friend, Eric. We had to wait in a hall outside the room where Eric was lying in his coffin for some time, waiting for the room to open. Almost the whole town stood in the hall. I saw my neighbor, Mr. Crandle, leaning up against the wall, taking his dusty cowboy hat off to swat some manure off of his boot. Mr. Jackson, the town mechanic and bartender at the High Mountain Tavern and Sport Shop, was talking in whispered tones to his short, plump wife. I began to wonder if Mr. Jackson owned any other clothes besides the stained, blue overalls that he wore all of the time. The mayor, Bob "The Bobber" Thompson, was the best dressed of them all in his faded, brown, pin-striped suit. I began to wonder why he was known to all as "The Bobber." As I probed deeper into this question, I was awakened from my thoughts by the scuffling of feet and saw everyone entering the room. I stood outside for a long time, not wanting to see Eric in his final resting place, wanting to remember him alive. As I entered the small, cramped room, some were trying to sing the hymn, "Father in Heaven, We Do Believe," while most wept, catching a final view of my friend before the oak coffin was closed and his earthly life was officially over. I was standing in the crowd, looking at Eric. He looked so peaceful, as if he was just sleeping and would wake up at any moment. The makeup on his face disturbed me. His skin was a bright peach color, his cheeks were pink, and his lips were full and red. He did not look like my friend, but like some sort of dead mime. His small, unmistakable smile eased my apprehensions, however, and the program went on. Suddenly, the crowd seemed to part in slow motion and I saw the man in the black suit standing before the coffin. He looked to be in his mid-twenties, and yet he seemed somehow to be much older. Perhaps it was his dark eyes that seemed to sink into his pale face or his thin frame that seemed so frail. His hair looked the same as the first day I met him, combed sideways as if his mother still did it for him. The Man in the Black Suit :: Personal Narrative Death Dying Essays The Man in the Black Suit We gathered together in our plain, small-town church for the funeral of my friend, Eric. We had to wait in a hall outside the room where Eric was lying in his coffin for some time, waiting for the room to open. Almost the whole town stood in the hall. I saw my neighbor, Mr. Crandle, leaning up against the wall, taking his dusty cowboy hat off to swat some manure off of his boot. Mr. Jackson, the town mechanic and bartender at the High Mountain Tavern and Sport Shop, was talking in whispered tones to his short, plump wife. I began to wonder if Mr. Jackson owned any other clothes besides the stained, blue overalls that he wore all of the time. The mayor, Bob "The Bobber" Thompson, was the best dressed of them all in his faded, brown, pin-striped suit. I began to wonder why he was known to all as "The Bobber." As I probed deeper into this question, I was awakened from my thoughts by the scuffling of feet and saw everyone entering the room. I stood outside for a long time, not wanting to see Eric in his final resting place, wanting to remember him alive. As I entered the small, cramped room, some were trying to sing the hymn, "Father in Heaven, We Do Believe," while most wept, catching a final view of my friend before the oak coffin was closed and his earthly life was officially over. I was standing in the crowd, looking at Eric. He looked so peaceful, as if he was just sleeping and would wake up at any moment. The makeup on his face disturbed me. His skin was a bright peach color, his cheeks were pink, and his lips were full and red. He did not look like my friend, but like some sort of dead mime. His small, unmistakable smile eased my apprehensions, however, and the program went on.
