...Programming File Organisation Serial File: In a serial file, the data is stored in the order in which it arrives. New data is simply added to the end of the file. This is called appending the data. If an item of data is to be deleted, this will create a gap in the file. This can be removed by recreating the file: copying all the records in the file, apart from the record to be deleted, into a new file and using this file to replace the original file. To search for data in a serial file, you will need to start from the first item and search for each item in turn until you find the record you are looking for. If the item you are searching for is not in the file, you will need to search every item in the file before you can be certain that the item is not found. Sequential File In a sequential file, the data are stored according to a key field in the data. The key field is a field in each record that can be used to identify the record. For example, if each student were given a StudentlD, then a sequential file of students will be stored in order of the Student ID. The addition of an item to a sequential file requires the new item to be inserted within the existing records. This is usually achieved by recreating the file. All the records up to the correct point of insertion are copied to a new file. The new record is then appended in the correct position and the remaining records are copied into the new file. The new file then replaces the old file. If an...

...PROCEDURES FOR CONDUCTING PRACTICAL ICT TESTS The Supervisor A suitably competent supervisor, who may be the candidates’ tutor, is responsible for the administration of the practical tests according to these instructions. The supervisor is responsible for the preparation of the hardware and software for the test. Timetabling of the Practical Tests CIE does not timetable the practical tests in the same way as most IGCSE and AS & A Level written papers. The IGCSE and AS & A Level timetable will specify a period within which candidates must take the two practical tests for each syllabus. Within this period, Centres may conduct the practical tests at any convenient time or times. Candidates must complete each practical test in a single session. Wherever possible, candidates from the same Centre should sit their assessment at the same time. If more than one session is necessary to accommodate all candidates, these sessions should follow on from each other. However, Centres do not need to sequester candidates until other candidates have taken the test. When arranging examination dates, Centres should take into account the time needed to set up the system and should allow contingency planning (e.g. to reschedule examination times due to possible hardware failure) wherever possible. Preparation for the Practical Tests Before the candidates take a practical test, the supervisor must work through a past/specimen paper, using the hardware and software that the candidates will be using...

...This customer data file is for 60,000 customer records in the restaurant category. Clean up the data: As with most customer data files, there is incomplete information. Address how you handle incomplete data. (I suggest completely eliminating records in Acquisition Channel with “NULL” or “Uncategorized”.) Also eliminate any records with blank in Ethnicity. Note in Ethnicity African-Americans is also coded as Afr. Am. so these two should be combined. In Age of Kids there are cells coded as Pre-teen &? I suggest combining with “Age Mix” or “Preteen & Teenagers”. After cleaning up the file, we are left with 26,352 records which should still be an adequate sample size.) Questions for analysis: 1. Calculate the profitability of each customer. Assume the average Cost of Goods Sold (COGS) for all vouchers (with promotional discounts factored in) is 20% of the total revenue. Assume the average one-time Cost per Acquisition (CPA) for each channel is: $12 for Advertising, $10 for Affiliate, $5 for Email, $8 for ILS, $7 for Paid Search and $5 for Social Media. Assume there are no additional costs. You may find the Excel VLOOKUP function helpful for this (https://support.office.com/en-sg/article/VLOOKUP-function-0bbc8083-26fe-4963-8ab8-93a18ad188a1). 2.

...Introducing Transaction Log Files Each SQL Server 2000 database has at least one transaction log file and can have multiple transaction log files spread across a number of disks. Each transaction log file is a separate operating system file and is used by only one database. Each transaction log file generally has the .ldf filename extension (this extension is not required). Each transaction log has a logical filename that is used in Transact-SQL statements and a physical filename that is used by the Windows operating system. Additional file properties include the file ID number, initial file size, file growth increment (if any), and maximum file size. Unlike data files that contain pages, transaction log files contain a series of transaction log records. A sequential log sequence number (LSN) identifies each transaction log record. Regardless of the number of physical log files, SQL Server 2000 treats the transaction log as one continuous log. SQL Server 2000 logically divides each physical transaction log file into a number of virtual log files (VLFs). The number and size of virtual log files are determined dynamically based on the size of each transaction log file. Each transaction log file has at least two VLFs. Each growth increment (if any) is treated as a separate physical file with its own VLFs. The number or size of VLFs cannot be configured or set directly by the database administrator. SQL Server 2000 tries to maintain a small number of virtual file logs because it operates...

...After watching the tutorials at the end of our lecture, I have found that there are more types of power then I thought of previously. Some of these seem to be effective, while others seem to be less effective. The ones that I find to be the most effective are Referent and Expert powers, I think it is much benefit in a hardworking approach to power, such as with the referent form of power. You can ensure that things get done in an easy and fair manner. Also with the expert form of power, you ensure that you are also on top of the situation, regardless of the surrounding factors, such as people or other stresses. I would like to believe that I have these types of power, but more commonly in my job, I use legitimate power. In most of the time at work I have to be the one to tell all my fellow employees what to do and how to meet our boss demands, therefore meeting our deadline of work is the most important part. Overall I am seen as the authoritative type of management but my boss is more uses of the coercive form of power, which I think is probably the least effective type. It almost makes me want to perform at a lower level when being treated in that way. When he does use this form of power, there are times where I do use some expert power by not responding in a negative way to his coercive attitude. Being aware of these types of power can able to help me identify which types of method I should use when I am the regarding situations, and it also helps me with my leadership skills...

...which they are day by day setting for their students. The questions of the final examinations should, therefore, be representatives of the types of educational objectives set in the different school subjects. The emphasis upon memory and some of the simpler types suggests a need for a modification in emphasis in most of the school subject. Frequently all questions are considered as belonging to one of two groups, “thought questions” or “memory questions”. Such a definite classification is not, however, always possible. The character of the mental process involved in answering depends upon the person replying as well as upon the form of the question asked. Those questions calling for definite facts are almost certain to be based upon memory; on the other hand, those requiring classification, evaluation, contrast, etc. are likely to demand thought on the part of most students. If, however, such classification or evaluations have been made in a previous class exercise some students may easily remember the answers and, in such a case, a thought question for one student becomes a memory question for another. (Monroe, 1923) Hence, the academic performance of a student mostly depend on his/her evaluation in exam. Students excel on either one of the two types or both. But oftentimes, examinees encounter problems in answering either one of the said types. Competitive/ Objectives exams are very much different than the board exams. As a result success in competitive exams requires a different...

...Audience Analysis Paper Adrian Perez Business Communication Kelly Parker Audience Analysis Paper In any organization or business, different types of meeting will take place with the organization which will involve different situations. It is critical to prepare for a business meeting especially when it involves stakeholders, your managers, salespeople, and customers. The main key to a successful meeting regardless of what is being presented is communication. How will the message be received? What type of audience will be attending? Is the message effective? All these points are important when preparing for a business meeting. There are different characteristics of the audience to consider when preparing for a meeting. When getting ready for the meeting, identify what kind of audience will attend. There are five different types of audiences to consider. One of them is the gatekeeper, which can stop the message and will not be received by other audiences. The primary audience decides if message will be accepted. The secondary audience can maybe implement ideas after they have been approved. The auxiliary audience will not interact with the message. Last but not least, the watchdog audience has political, social, or economic power, which can base future actions on the message. All these types of audiences are going to influence the message coming across. There are two important tools to realize when dealing with business meetings, common sense...

...of operating systems, this topic can be extremely important to a customer and designer of said system. Failures in a system can create catastrophic events that are costly in both monetary and emotional aspects. Faults within a system can be different in nature and can continue to wreak havoc on the system or to do nothing in some cases. Failures in distributed and centralized system can be specific in nature; however a generalized topic can describe the majority of these failures across the system. There are four types of failures in distributed systems that can affect functionality; but two of these four specific failures that can affect centralized systems as well. The general failures include: halting type failures, byzantine style failures, omission failures, and failures related to network issues. While all of these are important some of them affect a system more violently than others. The first types of failures to discuss are halting failures. These types of failures can be frustrating in nature since they affect most of the system and do not allow the operator to really investigate without rebooting the entire system. These failures essentially freeze the system without allowing any action to alleviate the issue. There can be many reasons for a halting failure such as hardware or software malfunctions, memory problems, or even viruses. Many of these problems can be solved by updating your system, acquiring memory that can create room to do some of the system work,...

...learn about the guidelines within a perfectly appropriate paper. Throughout the course I have found out there are many types of essays that are typed for appropriate matters or when it comes to certain points that need to stand out. There is the expository paper which is when you need to explain a theme or an idea to your intended audience and this style has a well-defined thesis. A persuasive essay is when you try to convince the audience or reader on a position you have about a certain topic or point of view. You are trying to persuade the readers and let them know you are correct. Analytical essay is when you analyze and examine a type of product which can consist of a book, poem or even a play or major even that happened. This essay basically explains the topic you want the audience to understand and you state the facts about the topic and inform them about everything you know with proof. Argumentative essays are a type of essay with your own personal opinion, theory and hypothesis about an issue that is correct and more truthful then those around you. This type is similar to a persuasive essay but the difference is that you are arguing your opinion instead of trying to let the audience agree or convert over to your point of view. I feel my writing has drastically improved after learning the types of essays I will be-able to write now. The way I used to type my papers was telling everything...

I moved a lot as a child and that too was a reason for me being so behind in my classes in school. I ended up taking this one math class for three years straight. -Was the test biased in any way? I do not believe that this test was biased in any way. I think that this test tested me in many aspects of intelligence and my score reflected on that. In order for this test to be biased it would have to persuade me towards a certain point and this test did not do anything like that. -How do you feel about these types of scores being used to compare you with another person?
