Why has one prominent textbook author described I/O management as the \"messiest aspect of operating system design\"? Using at least three distinct points, describe the evolution of I/O controllers, and describe how their support for I/O has increased in complexity over time. Solution Dear Student. Answer No-5a) The above asked question is from the book \"Opererating System by william Stalling\" according to the william stalling I/O management is the messiest aspect of an operating system. Let\'s discuss this in detail.. how I/O management is the messiest aspect of an operating system? There are wide variety of devices and their application. So it is very difficult to develop a generel consistant common solution for every device.The devices which are engaged with I/O are generally false in three different categories... 1-Human Readable- The human readable are the devices which are suitable for comuter user as printers, video display, mouse and keyboard.These are all input/output devices. 2-Machine Readable- The devices which are suitable for communication with electronic devices as disk drive, magnetic tapes and sensors and actuators. 3-Communication-The devices which are suitable for communicating with remote devices like a Modem. So above are the types of I/O devices, each device has their own functionality and design.Further more every device has different data transfer rate, and different applications. for example a disk used for file management requires support of file management software. Complexty in design is different in each device.Unit of data transfer may differ in each I/O device.Some are programmed I/O devices and some devices are interrupt driven, some requires DMA controller for data exchange between main memory and I/O module.Error conditions also differ from one device to another, So this kind of diversity makes uniform and consistant approach to I/O devices. So by the above explanation it is clear that is I/O is the messiest aspect of an operating system. Answer No-5b) As the coputer system is evoled there has been a pattern of increasing complexity and shopistication of each individual component.the evolutionarry steps in I/O controller are described below... The best example of I/O controller is DMA(Direct Memory Access).It controlles the data transfer between memoy and I/O device.The evolution of I/O controller is as follows.. 1- Previously processor directly controlled a peripheral device.Then a controller or I/O is added for smooth and fast data transmission. 2-Then I/O controller given direct memory controll via DMA controllers.And now the DMA controller can move a block of data without involving the processor. 3- Further I/O controller enhanced to become a seperate processor the central processing unit direcly direct the I/O processor to execute an I/O program in memory. So as the envolved continues in I/O Controller, more and more I/O functions is performed without processor involvement.Thats is why the complexity h.

What is the value of studying humanities in a business or technical curriculum? Solution Having learned more about the myths and stories of Western civilization, I am understanding more how study of the humanities (art, history, and literature) can be used to help people better understand and communicate with one another. It is obvious that the study of humanities is not just a college course, but it is an ongoing process and practice in life. The humanities can first be used to understand the past which has created the present. The culture which we have was shaped by the past. Facts, findings, and literature of even thousands of years ago have influenced our world today. Knowing this past can allow people to understand our present; knowing how we came to this present helps us to communicate about it and the future. The study of the humanities can also be used to realize differing interpretations of life and history. Studying facts of the past helps to understand literature of the past. Art reflects the cultures of the past, and shows how we achieved what we have today. For example, the Song of Roland was very biased about the Saracens (Muslims). If one only studied literature, they would have a totally skewed interpretation of who the Muslims were. By studying history though, we know that the battle in this literature wasn\'t even against Muslims. Also by studying history and religion we can see how Islam developed and what it really is. This is just one example of how the comprehensive study of the humanities can be used to understand the world, and to communicate fairly and intelligently with others in the world. The humanities are not just part of the college\'s curriculum. The study of the humanities teaches one how to study and look at how the past developed and how it has impacted today\'s world. The humanities allows people of different cultures to communicate and understand their sometimes common pasts but present differences. The humanities shows how different disciplines affect and complement one another. Finally, the study of the humanities shows that this study is ongoing and continual, constantly evolving and shaping. Highly successful executives, entrepreneurs and policy makers offer words of wisdom about the practical value of studying the humanities. “I think if you have a good background in what it is to be human, an understanding of life, culture and society, it gives you a good perspective on starting a business, instead of an education purely in business...You can always pick up how to read a balance sheet and how to figure out profit and loss, but it\'s harder to pick up the other stuff on the fly. ” 1. The humanities prepare you to fulfill your civic and cultural responsibilities. The reason that John Harvard left his library to the college in Cambridge, Massachusetts, that Jane and Leland Stanford founded Stanford University, and that states established land-grant colleges was to educate cultured and useful citizens.

There are 40 students in our class. How many ways they can be lined up such that two fixed students X and Y are next to each other (order of the two fixed students does not matter). Solution So now that X and Y are always beside each other, then you can treat them as just ONE PERSON. Thus, it\'s like there are now just 39 people to permute. As n! = number of ways to permute n objects in a line, then the number of ways is #ways = 39! = 2.03979*10^46 [ANSWER].

The Task For this assignment you will write a rudimentary text editor that allows the user to edit 5 lines of text, where each line is no longer than 80 characters. The editor should allow the user to continue editing as long as desired and should print the current state of the edit buffer after each edit. The editor is a \'line editor\' in that the user must edit one line at a time. The user can specify which line should be edited by choosing a line number from a menu. The only two editing operations possible are to replace an entire line with a new line, or to replace a substring in the line with a new substring. Musts The program should not accept incorrect menu choices from the user. If the user creates a string that is longer than 80 characters the string should be truncated to fit the 80 character limit. The program should simply make no changes if the user tries to replace a substring that does not exist in the string. Your program must use functions. Some functions are required, but you may make other functions as you see fit. You may not change the name, return type, or the parameter list types for required functions. Required Function One int replaceInString(char[] original, char[] substring, char[] replace); This function causes the original string to be modified such that the first occurrence of substring is removed from the original string and the contents of replace are inserted in its place. replaceInString calls findSubString and insertString. The function returns 0 if the operation fails and 1 if the operation is successful. Required Function Two: int findSubString(char[] original, char[] toFind); This function finds the first occurrence of toFind in original and returns an integer representing the index of the first element of the toFind substring in original. For example if toFind was \'cat\' and original was \'thundercat\' the function would return 7 since the begining of \'cat\' in \'thundercat\' is position 7. If the function does not find a substring it should return -1 note: do not use existing substring functions such as strstr as a solution for this function. Solve the algorithm yourself. You may use basic string functions such as strlen and strcat. Required Function Three: int insertString(char[] original, int start, int length, char[] toInsert); This function replaces the contents of original with the following sequence of characters: the characters from original up to position start- the characters from toInsert the characters from original starting at the character immediately after length. Solution #include #include #define ROW_LENTH 81 #define NUM_ROWS 5 void replaceLine(char line[]); void printText(char text[][ROW_LENTH]); int readFile(char filePath[], char text[][ROW_LENTH]); int writeFile(char filePath[], char text[][ROW_LENTH]); void removeTrailingHardReturn(char line[]); void flushBuffer(); int getLine(); int replaceInString(char original[], char substring[], char replace[]); int findSubString(char origina.

The following results were obtained in the patient from Case Study 25-2 (Case Study Table 25- 4.1). What is the most likely diagnosis? What is the prognosis? What complications may develop? Solution Ques-1 Diagnosis: From the laboratory diagnosis, it seems that the patient is suffering from multiple infections from hepatitis, including A and B. Both of these forms of hepatitis infections occur due to infected food/water and direct physical contact Ques-2: The major prognosis of hepatitis A & B is to infect liver because cirrhosis finally lasts for 3 to 4 months. Under chronic conditions, it lasts for 6 months due to hepatic cell infection due to hepatitis B virus replication. This is leading to higher incidence of hepatitis core antibody (lgM) so that it is positive Ques-3: Complications: Hepatitis or jaundice is the medical term for yellow discoloration of the sclera and mucous membranes. Heme moiety of hemoglobin is breakdown into iron and bilivirdin in the body. During jaundice, excess breakdown of hemoglobin results in the accumulation of bilirubin (made from bilivirdin), which gives yellow coloration to the mucous membranes. The most common symptoms include flu-like asscoaited with aches, liver dysfunction finally tiredness, diarrhea. The main pain and ache observed in the liver region due to viral invasion of hepatocytes causes inhibition of metabolic enzyme synthesis and metabolic enzyme activity. These symptoms are leading to severe ache below the ribs and near to abdomen specifically in liver.
