Question 1: In computers, how are text characters represented for storage and processing?
A) As images with corresponding pixels.
B) Through voice recognition software.
C) By assigning random numbers to each character.
D) As unique patterns of bits (0s and 1s).
Explanation: Text is converted into a binary code for computers to understand.
Question 2: How many bits are typically used to represent a single character with the most common code, ASCII?
A) 4 bits
B) 6 bits
C) 8 bits
D) 16 bits
Explanation: ASCII uses 8 bits per character, allowing for 256 different characters.
Question 3: The text “Virtual University” is 18 characters long. How many bits are required to store it using ASCII encoding?
A) 72 bits
B) 144 bits
C) 288 bits
D) It depends on the font size.
Explanation: 18 characters * 8 bits/character = 144 bits
Question 4: Which organization developed the American Standard Code for Information Interchange (ASCII)?
A) World Wide Web Consortium (W3C)
B) American National Standards Institute (ANSI)
C) International Organization for Standardization (ISO)
D) Institute of Electrical and Electronics Engineers (IEEE)
Explanation: ANSI is responsible for standardizing ASCII.
Question 5: What is a limitation of the original ASCII code?
A) It uses uppercase letters only.
B) It cannot represent numbers.
C) It has a limited set of characters (128).
D) It requires special software for interpretation.
Explanation: ASCII cannot represent all symbols and characters used in various languages.
Question 6: The International Organization for Standardization (ISO) developed extensions to ASCII for what purpose?
A) To create a more complex code.
B) To support additional characters used in different languages.
C) To increase the speed of data transfer.
D) To create a code specifically for numbers.
Explanation: ISO extensions aim to address the limitations of ASCII for international use.
Question 7: Why are 256 characters, even with extensions, still insufficient for representing all written languages?
A) The extensions are not widely adopted.
B) Some languages have a vast number of symbols
C) The code is case-sensitive.
D) The bit patterns are too complex.
Explanation: Many languages have characters beyond the capacity of basic ASCII extensions.
Question 8: What is the primary goal of Unicode encoding?
A) To replace ASCII completely.
B) To simplify text representation.
C) To provide a universal character encoding standard for various languages.
D) To improve data security.
Explanation: Unicode aims to represent a vast range of characters for global communication.
Question 9: How many bits does Unicode typically use to represent a character?
A) 8 bits
B) 12 bits
C) 32 bits
D) Up to 21 bits
Explanation: Unicode uses a variable-length encoding scheme, allowing for a wider range of characters.
Question 10: How does UTF-8 relate to Unicode?
A) They are completely different encoding systems.
B) UTF-8 is a specific way of encoding characters based on the Unicode standard.
C) UTF-8 is a simpler version of ASCII.
D) UTF-8 is used for storing images.
Explanation: UTF-8 is a popular encoding scheme that implements Unicode using 1 to 4 bytes per character.
Question 11: What is the advantage of UTF-8 encoding compared to ASCII?
A) It requires less storage space for all characters.
B) It is faster for processing English text.
C) It can represent a wider range of characters from various languages.
D) It is only used for special applications.
Explanation: UTF-8’s variable-length encoding allows for more characters than ASCII.
Question 12: A file containing text with English characters, numbers, and some punctuation symbols is most likely encoded using:
A) Unicode (capable of a very wide range of characters)
B) A custom encoding specific to the file (unlikely for common text)
C) UTF-8 (a way of implementing Unicode, but overkill for basic text)
D) ASCII (covers basic English characters, numbers, and punctuation)
Explanation: ASCII is sufficient for the characters described and is a widely used standard encoding.
Question 13: How does the number of bits used to represent a character affect the total storage space required for text?
A) It has no impact.
B) More bits per character lead to a smaller storage footprint.
C) More bits per character require more storage space
D) None
Explanation: Each bit occupies memory, so more bits per character translate to increased storage needs.
Question 14: What is the benefit of a standardized character encoding system like ASCII or Unicode?
A) It makes text files larger and more complex.
B) It ensures consistent representation of characters across different devices and software.
C) It restricts users to a limited set of characters.
D) It requires special fonts for display.
Explanation: Standardization allows computers to understand text regardless of the source.
Question 15: When referring to a “text file,” what does it imply about the encoding used?
A) The text is encrypted for security purposes.
B) The text is formatted in a specific style (bold, italics, etc.).
C) The text is encoded using a character set like ASCII or Unicode.
D) The text is displayed in a particular font size.
Explanation: Text files store characters using a defined encoding scheme.
Question 16: Imagine a document containing both English text and Chinese characters. Which encoding would be most suitable?
A) ASCII (limited to basic English characters)
B) Unicode (supports a vast range of characters)
C) A custom encoding specific to the document
D) It depends on the font used for the Chinese characters.
Explanation: Unicode’s wide character support makes it ideal for multilingual documents.
Question 17: What potential issue can arise when opening a text file encoded in one format (e.g., UTF-8) with software that expects a different format (e.g., ASCII)?
A) The file size will be significantly larger.
B) The text will be displayed in a different font.
C) Characters not supported by the expected format may appear incorrectly or be missing.
D) The text will be read-only.
Explanation: Encoding mismatch can lead to garbled or missing characters.
Question 18: How can you ensure a text file is displayed correctly with various software and devices?
A) Use a specific font for the entire document.
B) Save the file using a widely supported encoding like UTF-8.
C) Convert the text to an image format (e.g., JPEG).
D) There’s no guaranteed method for universal compatibility.
Explanation: UTF-8’s broad compatibility increases the likelihood of correct display.
Question 19: When working with text files containing symbols or characters from different languages, what should you consider before sharing the file with others?
A) The font size used in the document
B) The encoding format used and whether the recipient’s software can support it.
C) The color scheme used for highlighting text
D) The specific keyboard used to type the text
Explanation: Ensure the recipient’s system can interpret the chosen encoding.
Question 20: New character encoding standards are constantly being developed. Why might this occur?
A) To intentionally break compatibility with older systems.
B) To accommodate new symbols, languages, or special characters.
C) To make text files smaller and more efficient.
D) To create a more complex encoding scheme for security purposes.
Explanation: New encoding standards may be needed to represent characters not previously supported.
