Fields are composed of bytes
Files are composed of records
Fields are composed of characters
Records are composed of fields E. All of the above
Answer is Right!
Answer is Wrong!
The correct answer is: E. All of the above
A field is a single piece of information in a record. It is composed of characters, which are the smallest unit of data in a computer. A record is a group of related fields. A file is a collection of records.
For example, a customer record might have fields for the customer’s name, address, phone number, and email address. A file of customer records might contain records for all of the customers of a company.
Here is a more detailed explanation of each option:
- Fields are composed of bytes. A byte is a unit of data that is typically eight bits long. A bit is the smallest unit of data in a computer, and it can be either a 0 or a 1. Eight bits can represent 256 different values, so a byte can represent up to 256 different characters.
- Files are composed of records. A record is a group of related fields. A field is a single piece of information in a record. For example, a customer record might have fields for the customer’s name, address, phone number, and email address.
- Fields are composed of characters. A character is a single letter, number, or symbol. Characters are represented in computers by bytes. Each byte can represent up to 256 different characters.
- Records are composed of fields. A record is a group of related fields. A field is a single piece of information in a record. For example, a customer record might have fields for the customer’s name, address, phone number, and email address.
