- A sorted file has the following details: Number of records = 13,10,720; record length = 200 bytes; size of the primary key field = 13 bytes; size of block pointer = 7 bytes; block size = 2048 bytes. For this file, we need to build a multi-level index on the primary key. The number of blocks in the first level index file isA temperature file consists of five records, each containing a temperature in degrees Fahrenheit. A program is to be written that will read the input temperature, convert it from degrees Fahrenheit to degrees Celsius and print both temperatures in two columns on a report. Column headings, which read ‘Degrees F’ and ‘Degrees C’, are to be printed at the top of the page. What ist he best solution algorithm to successfully implement the above question?Pleaser refer on the attached file.
- Create a data file in Python using open, write and close functions. Your data file should contain your personal information: Complete name, student number, date of birth, and complete address help me here complete name: cloe jake gonzales student number: 12-1485 date of birth: january 12 1982 complete add: anastasia,1485 sokor, UAEGimme Shelter Roofers maintains a file of past customers, including a customer number, name, address, date of job, and price of the job. It also maintains a file of estimates given for jobs not yet performed; this file contains a customer number, name, address, proposed date of job, and proposed price. Each file is in customer number order. Design the logic that merges the two files to produce one combined file of all customers whether past or proposed with no duplicates; when a customer who has been given an estimate is also a past customer, use the proposed data. (flowchart or pseudocode)Two data files are required to evaluate a multiple-choice examination. The first file (booklet.dat) (memo) contains the correct answers. The total number of questions is 50.

- A file has r = 20, 000 STUDENT records of fixed length. Each record has the following fields: NAME (30 bytes), SSN (9 bytes), ADRESS(40 bytes), PHONE(9 bytes), BIRTHDATE (8 bytes), SEX(1 byte), CLASSCODE( 4 bytes, integer) MAJORDEPTCODE(4 bytes), MINORDEPTCODE(4 bytes), and DEGREEPROGRAM( 3 bytes). An additional byte is used as a deletion marker. Block size B = 512 bytes. a) Calculate the blocking factor bfr (=floor(B/R), where R is the record size) and number of file blocks b, assuming unspanned organization (a record can’t be split across blocks). b) Suppose only 80% of the STUDENT records have a value for PHONE, 85% for MAJORDEPTCODE, 15% for MINORDEPTCODE, and 90% for DEGREEPROGRAM. We use a variable-length record file. Each record has a 1-byte field type for each field in the record, plus the 1-byte deletion marker and a 1-byte end-of-record marker. Suppose that we use a spanned record organization, where each block has a 5-byte pointer to the next block (this space is not used…In Unix You have a record structured file named mydata that has four columns with default delimiter (white space).

- Explain the difference between Sequential Files and Random Files? Why is it important to close the File objects after using them in the code?This function is used to create a bank dictionary. The given argument is the filename to load. Every line in the file should be in the following format: key: value The key is a user's name and the value is an amount to update the user's bank account with. The value should be a number, however, it is possible that there is no value or that the value is an invalid number. What you will do: - Create an empty bank dictionary. - Read in the file. - Add keys and values to the dictionary from the contents of the file. - If the key doesn't exist in the dictionary, create a new key:value pair. - If the key does exist in the dictionary, increment its value with the amount. - You should also handle the following cases: -- When the value is missing or invalid. If so, ignore that line and don't update the dictionary. -- When the line is completely blank. Again, ignore that line and don't update the dictionary. -- When there is whitespace at the…If a file contains an index directory that allows for random access, what does it mean?
