A procedure isFound, which takes a word and a text file as input and returns true if the word appears in the text file. To read a file in Python, we can loop over the file and complete the necessary task by using the file object as an iterator to read big text files.
The best method for searching a string in a big text file in terms of speed and memory usage is using a file in read-only mode.
To obtain a line and its number, use a for loop using the enumerate() method. An iterable is given a counter by the enumerate() function, which returns the object as an enumerate object. Give the enumerate function the file pointer returned by the open() function (). This enumerate object can be used in a for loop to access each line and its corresponding line number.
Note that this is an effective workaround because enumerate(file pointer) doesn't load the complete file into memory.

Which of the following procedures would be most useful as part of a program to determine whether a word appears in two different text files?
A procedure getWords, which takes a positive integer n and a text file as input and returns the first n words in the text file.A procedure textMatch, which takes two text files as input and returns true if the two text files are identical.A procedure isFound, which takes a word and a text file as input and returns true if the word appears in the text fileA procedure sameSize, which takes two text files as input and returns true if the two text files contain the same number of words.(short answer) some operating systems provide a system call rename( ) to give a file a new name. answer these questions from the perspective of the file systems actions, not as how an application might view them when it calls these functions.
To rename a file, certain operating systems include the system function RENAME. Is there any distinction between renaming a file with this method and simply transferring it to a new file with the new name, then deleting the old one? Yes. The creation and modification timeframes are unaffected by renaming.
What is an operating system?Although there are many operating systems available, Microsoft's Windows, Apple's macOS, and Linux are the three most widely used.All I/O device, memory, CPU, and file storage resources are managed by the operating system (OS), which assigns them to particular programs and users as needed to carry out tasks.An operating system has three functions: (1) managing the computer's resources, such as the CPU, memory, disk drives, and printers; (2) developing a user interface; and (3) running and supporting application software.An operating system is a type of system software that controls the resources used by computers' hardware and software while also offering standard services to its software programs.To learn more about Operating System refer to:

when you translate a problem and encode it into a spreadsheet, the first thing you should do is consider using absolute cell referencing.
When you translate an issue and encode it into a spreadsheet, the first thing you should do is consider employing absolute cell referencing.
Named ranges are always considered as absolute cell references. To minimize time-consuming adjustments later, consider a workbook design before implementing a solution. An absolute reference in Excel is a cell reference in which the column and row coordinates remain unchanged while copying a formula from one cell to the other.
To adjust the coordinates, a dollar sign ($) is used before them. For example, $D$2 is a direct reference to cell D2. Cell references are classified into two types: relative and absolute. When copied and filled into other cells, relative and absolute references act differently. When a formula is transferred to another cell, the relative references change.
Absolute references, on the other hand, do not change regardless of where they are duplicated. In Excel, an absolute reference is one that is 'locked' such that the rows and columns do not change when copied. It is expressed by inserting a '$' symbol before the row and column names.

listen to exam instructions you are installing a new sata hard drive in your windows workstation. which of the following connectors should you use to connect your hard drive to the motherboard? answer:
A. 50-pin connector B. 40-pin connector C. 80-pin connector
D. 7-pin connector
Listen to exam instructions you are installing a new sata hard drive in your windows workstation. 7-pin connector should you use to connect your hard drive to the motherboard.
When installing a new SATA hard drive in a Windows workstation, you'll need to connect it to the motherboard in order to communicate with the rest of the computer system. There are several types of connectors that can be used for this purpose, including 50-pin, 40-pin, and 80-pin connectors. However, the most common connector for SATA hard drives is the 7-pin SATA connector.
The 7-pin SATA connector is designed specifically for SATA hard drives and provides a fast and reliable data transfer rate of up to 6 Gbps. The 7-pin SATA connector has 7 pins arranged in a specific manner to ensure proper connectivity and prevent damage to the hard drive or motherboard.
To connect your SATA hard drive to the motherboard using a 7-pin SATA connector, you'll need to locate the SATA ports on the motherboard and plug in the hard drive cable. The hard drive cable should snap into place securely, and the SATA ports on the motherboard should provide power to the hard drive.
Once the hard drive is connected, you'll need to configure the BIOS or UEFI settings to recognize the new hard drive and assign it a drive letter. After that, you can install an operating system and use the hard drive as a storage device.

when the provided integer n is divisible by 3, print fizz. when the provided integer is divisible by 5, print buzz. when it is divisible by both 3 and 5, print fizzbuzz. otherwise print the integer. you need to fill in a condition (using boolean operators) for each of the four cases.
Here is a solution in Python using the modulo operator '%':
def fizzbuzz(n):
if n % 3 == 0 and n % 5 == 0:
print("fizzbuzz")
elif n % 3 == 0:
print("fizz")
elif n % 5 == 0:
print("buzz")
else:
print(n)
The modulo operator '%' returns the remainder of a division. So, n '%' 3 == 0 is True if n is divisible by 3, and n '%' 5 == 0 is True if n is divisible by 5.
The first if statement checks if n is divisible by both 3 and 5. If so, it prints "fizzbuzz".
The second elif statement checks if n is divisible by 3. If so, it prints "fizz".
The third elif statement checks if n is divisible by 5. If so, it prints "buzz".
The else statement is executed if none of the previous conditions are met, and prints the integer n.
