Automated Standard Character Input
What is a primary limitation of ASCII when representing text?
It is not widely compatible with most computer systems.
It can only represent numeric data, not alphabetical characters.
It only supports English text and cannot represent characters from other languages or emojis.
It results in very large file sizes compared to other text formats.
Numeric files can be represented directly in binary or through ASCII. What is a potential drawback of representing numeric data using ASCII compared to direct binary representation?
ASCII representation is less widely compatible.
ASCII representation is typically longer, leading to larger file sizes.
ASCII representation cannot accurately store decimal numbers.
ASCII representation is only suitable for very small numbers.
In Information Technology, what characteristic defines a "plain text file"?
It contains only numerical data.
It includes advanced formatting like bolding, italics, and different fonts.
It stores text without any additional formatting.
It is exclusively used for programming code.
What is the main purpose of a Comma-Separated Values (CSV) file?
To store simple, unformatted text documents.
To embed images and multimedia content within text.
To store data in a table form, using commas to separate values.
To create highly formatted documents with complex layouts.
What is a primary characteristic of a TXT file?
It supports complex formatting and embedded images.
It stores data in a table format with comma separators.
It is used for storing simple text without additional formatting.
Each column has a fixed number of characters.
Which statement accurately describes a CSV file?
It uses tags to define data elements.
It stores data in a table format using commas to separate values.
It allocates a fixed number of characters for each data field.
It is primarily used for storing unformatted plain text.
A data file format where each column is assigned a predetermined number of characters, potentially leading to wasted space, is known as a:
TXT file
CSV file
XML file
Fixed Width file
What is a key feature of XML for structuring data?
It uses key-value pairs for data representation.
It separates data fields using commas.
It relies on tags to define and organize data elements.
It ensures the smallest possible file size for data exchange.
Which of the following is an advantage of JSON over XML for data exchange?
JSON files are typically larger in size.
JSON uses a more complex tag-based structure.
JSON is slower to process due to its verbose nature.
JSON files are smaller in size and faster to process.
