    Which of the following is not permanent storage?

    • RAM

    • A hard disk

    • A USB drive

    • All of these

    Correct Answer
    A. RAM
    Explanation
    RAM (Random Access Memory) is not permanent storage because it is a type of volatile memory that is used to store data temporarily while the computer is running. Unlike a hard disk or a USB drive, which are non-volatile and can retain data even when the power is turned off, the data stored in RAM is lost when the power is disconnected. Therefore, RAM is not a permanent storage solution.

    A collection of data stored on a nonvolatile device in a computer system is a(n) __________.

    • Application

    • computer file

    • Operating system

    • Memory map

    Correct Answer
    A. computer file
    Explanation
    A computer file is a collection of data stored on a nonvolatile device in a computer system. It can contain various types of information, such as text, images, audio, or video. Computer files are organized and managed by the operating system, and they can be accessed and manipulated by applications. They provide a way to store and retrieve data for different purposes, such as saving documents, running programs, or storing multimedia content.

    A character used to specify the boundary between data items in text fi les is a __________.

    • Sentinel

    • Stopgap

    • Delimiter

    • margin

    Correct Answer
    A. Delimiter
    Explanation
    A delimiter is a character used to separate or mark the boundaries between data items in text files. It helps to organize and structure the data, allowing for easier parsing and processing. Delimiters can be any character, such as a comma, tab, or semicolon, that is agreed upon and used consistently throughout the file. They serve as indicators for where one piece of data ends and the next one begins. In the context of the given question, a delimiter is the correct answer as it accurately describes the character used for this purpose in text files.

    Random access memory is __________.

    • Persistent

    • Volatile

    • Permanent

    • Sequential

    Correct Answer
    A. Volatile
    Explanation
    Random access memory (RAM) is volatile because it is a type of computer memory that can only hold data temporarily. When the power supply to the computer is turned off, the data stored in RAM is lost. This is in contrast to permanent storage devices like hard drives or solid-state drives, which can retain data even when the power is off. Volatility in RAM allows for fast and efficient data access, but it also means that the data needs to be constantly refreshed or saved to a more permanent storage medium to avoid loss.

    The process of converting objects into streams of bytes is __________.

    • Extrication

    • Splitting

    • Mapping

    • Serialization

    Correct Answer
    A. Serialization
    Explanation
    Serialization is the process of converting objects into streams of bytes. It allows objects to be easily stored, transmitted, and reconstructed later on. This process is commonly used in programming to save and transfer data in a platform-independent manner. By serializing objects, the data they contain can be written to a file, sent over a network, or stored in a database.

    Rate this question:

  • 7. 

    When each record in a fi le is stored in order based on the value in some fi eld, the fi le is a(n) __________ file.

    • Random access

    • Application

    • Formatted

    • Sequential

    Correct Answer
    A. Sequential
    Explanation
    A sequential file is a type of file where each record is stored in order based on the value in some field. This means that the records are arranged in a sequential manner, one after the other. This type of file is commonly used when the data needs to be accessed or processed in a sequential manner, such as reading the file from start to end. Unlike random access files, sequential files do not allow direct access to specific records.

     Th e String class Split() method stores its results in __________.

    • A string

    • An array of strings

    • an appropriate data type for each token

    • an array of bytes

    Correct Answer
    A. An array of strings
    Explanation
    The Split() method of the String class in Java stores its results in an array of strings. When the Split() method is called on a string, it splits the string into multiple substrings based on a specified delimiter and stores each substring as an element in an array of strings. This allows for easy access and manipulation of the individual substrings.

    Rate this question:

  • 9. 

    Which of the following is not a File class method?

    • Create()

    • Delete()

    • Exists()

    • End()

    Correct Answer
    A. End()
    Explanation
    The End() method is not a File class method. The Create() method is used to create a new file, the Delete() method is used to delete a file, and the Exists() method is used to check if a file exists. However, the End() method does not exist in the File class and therefore is not a valid option.

    Rate this question:

  • 10. 

    Which character can be used to specify a boundary between characters in text fi les?

    • A comma

    • A semicolon

    • Either of these

    • Neither of these

    Correct Answer
    A. Either of these
    Explanation
    Both a comma and a semicolon can be used to specify a boundary between characters in text files. A comma is commonly used as a delimiter in CSV (Comma-Separated Values) files, while a semicolon is often used in other file formats. Therefore, either of these characters can be used as a boundary in text files depending on the specific file format and requirements.

    Which of the following is not a FileStream property?

    • CanRead

    • CanExist

    • CanSeek

    • CanWrite

    Correct Answer
    A. CanExist
    Explanation
    The CanExist property is not a valid FileStream property. FileStream is a class in C# that represents a stream for reading and writing files. It provides properties such as CanRead, CanSeek, and CanWrite to check the capabilities of the stream. However, there is no CanExist property defined for FileStream.

    A channel through which data flows between a program and storage is a __________.

    • Path

    • folder

    • stream

    • Directory

    Correct Answer
    A. stream
    Explanation
    A channel through which data flows between a program and storage is referred to as a stream. Streams provide a way for programs to read or write data to and from storage devices, such as files or network connections. They act as a bridge that allows the program to interact with the data in a sequential manner, making it easier to handle large amounts of information efficiently.

    In the data hierarchy, a group of characters that has some meaning, such as a last name or ID number, is a __________.

    • Byte

    • Field

    • File

    • Record

    Correct Answer
    A. Field
    Explanation
    A field is a group of characters that has some meaning, such as a last name or ID number. It is a basic unit of data in a database or a record. Fields are used to store specific types of information and are organized within records, which in turn are organized within files.

    Rate this question:

  • 14. 

    A file’s __________ holds the byte number of the next byte to be read.

    • Index indicator

    • Position pointer

    • Header file

    • Key field

    Correct Answer
    A. Position pointer
    Explanation
    The correct answer is "position pointer." In a file, the position pointer is a variable that keeps track of the byte number of the next byte to be read. It is used to determine the current position within the file and is updated as bytes are read or written. The position pointer helps in navigating through the file and accessing specific data at different positions.

    Th e argument to the String class Split() method is __________.

    • void

    • the number of fi elds into which to split a record

    • The character that identifi es a new fi eld in a string

    • A string that can be split into tokens

    Correct Answer
    A. The character that identifi es a new fi eld in a string
    Explanation
    The argument to the String class Split() method is the character that identifies a new field in a string. This argument is used to specify the delimiter or separator that is used to split the string into multiple parts or tokens. The Split() method will split the string at each occurrence of the specified character and return an array of substrings.

    Which of the following is not part of a FileStream constructor?

    • The file size

    • The file mode

    • The filename

    • The type of access

    Correct Answer
    A. The file size
    Explanation
    The file size is not part of a FileStream constructor because the size of the file is determined by the actual content of the file, rather than being specified during the construction of the FileStream object. The FileStream constructor is used to create a new FileStream object and requires parameters such as the file mode, filename, and type of access, but not the file size.

    Rate this question:

  • 17. 

    Which of the following is not a fi le Access enumeration?

    • Read

    • Write

    • WriteRead

    • ReadWrite

    Correct Answer
    A. WriteRead
    Explanation
    The correct answer is "WriteRead". This is not a valid file access enumeration because it combines both the "Write" and "Read" access permissions into a single option. Typically, file access enumerations are separate options for each type of access, such as "Read", "Write", and "ReadWrite" (which allows both read and write access).

    Rate this question:

  • 18. 

    After a StreamReader has been created, the ReadLine() method can be used to __________.

    • Retrieve one line at a time from the file

    • Retrieve one character at a time from the fi le

    • Store one line at a time in a fi le

    • split a string into tokens

    Correct Answer
    A. Retrieve one line at a time from the file
    Explanation
    After a StreamReader has been created, the ReadLine() method can be used to retrieve one line at a time from the file. This method reads the next line of characters from the input stream and returns it as a string. It allows for sequential reading of a text file, where each call to ReadLine() retrieves the next line until the end of the file is reached.

    Rate this question:

  • 19. 

    When you store data in a computer file on a persistent storage device, you are __________.

    • Reading

    • Directing

    • Writing

    • Rooting

    Correct Answer
    A. Writing
    Explanation
    When you store data in a computer file on a persistent storage device, you are "writing" the data. Writing refers to the process of saving or recording data onto a storage device, such as a hard drive or solid-state drive, for future retrieval and use. This action involves transferring the data from the computer's memory to the storage device, ensuring that it is stored and preserved for later access.

    Rate this question:

  • 20. 

    When a fi le’s mode is Create, a new fi le will be created __________.

    • Even if one with the same name already exists

    • Only if one with the same name does not already exist

    • Only if one with the same name already exists

    • Only if the access is Read

    Correct Answer
    A. Even if one with the same name already exists
    Explanation
    When a file's mode is set to Create, it means that a new file will be created regardless of whether or not a file with the same name already exists. This means that even if there is already a file with the same name, the Create mode will still create a new file with that name.
