Describe the advantages of using a FileInputStream over a FileReader when dealing with binary data.
Step by step
Solved in 6 steps
- DataInputStream reads bytes from the stream and converts them into appropriate primitive type values or strings.Does the accumulation of entries in a file cause it to cluster?Design a pseudocode algorithm for reversing the contents of a text file into another file. Assume that the amount of memory is limited, so that you cannot read the entire source file into memory before you start writing it to a second file in reverse order.
- Explain the difference between Sequential Files and Random Files? Why is it important to close the File objects after using them in the code?Write example of C++ program that reads and writes a binary file to a text file. It also prints the values accordingly to the consoleWhat is the distinction between a file's logical description and its physical description?
- Computer Science Write a python program that reads the data file https://archive.ics.uci.edu/ml/machine-learning-databases/eventdetection/CalIt2.data and finds the total count of outflow and the total count of inflow. The attributes in the file are as follows: 1. Flow ID: 7 is out flow, 9 is in flow 2. Date: MM/DD/YY 3. Time: HH:MM:SS 4. Count: Number of counts reported for the previous half hour Rows: Each half hour time slice is represented by 2 rows: one row for the out flow during that time period (ID=7) and one row for the in flow during that time period (ID=9) Hint: # Importing the dataset dataset = pd.read_csv('CalIt2.data') https://archive.ics.uci.edu/ml/machine-learning-databases/event-detection/CalIt2.data this link should work.POWERSHELL TASK Try to swap two strings/names in a file and the file name should be a command-line argument.An application loads 100 libraries at start-up. Loading each library requires exactly one disk access. The seek time of the disk to a random location is given as 10 ms. Rotational speed of disk is 6000 rpm. If all 100 libraries are loaded from random locations on the disk, how long does it take to load all libraries? (The time to transfer data from the disk block once the head has been positioned at the start of the block may be neglected.)
