What does a record represent?
Record – a record represents a collection of attributes that describe a real-world entity.
How it is represented in memory?
A piece of computer memory can be represented by a series of 0’s and 1’s, with one digit for each bit of memory; the value 1 represents an “on” bit and a 0 represents an “off” bit. A single word of memory contains 32 bits, so it requires 32 digits to represent a word in binary form.
How records are represented in memory using arrays?
Each data item may be a group item composed of sub items. To present this record in memory, linear arrays are used. The records are stored in memory using parallel linear arrays, such that for an index K of all records, First name [K], Last name [K], Sex [K].. belong to the same record in a file.
How stack is represented in memory?
A stack is usually represented in computers by a block of memory cells, with the “bottom” at a fixed location, and the stack pointer holding the address of the current “top” cell in the stack.
How are queue represented in memory?
We can easily represent queue by using linear arrays. There are two variables i.e. front and rear, that are implemented in the case of every queue. Front and rear variables point to the position from where insertions and deletions are performed in a queue.
What does a record called?
phonograph
phonograph, also called record player, instrument for reproducing sounds by means of the vibration of a stylus, or needle, following a groove on a rotating disc. A phonograph disc, or record, stores a replica of sound waves as a series of undulations in a sinuous groove inscribed on its rotating surface by the stylus.
How is circular queue represented?
A circular queue is a linear data structure that follows FIFO principle. In circular queue, the last node is connected back to the first node to make a circle. In Circular queue elements are added at the rear and elements are deleted from front. We can represent circular queue using array as well as linked list.

What is an a record?
A record is any document (paper or electronic) created or received by offices or employees that allows them to conduct business. This definition includes, but is not limited to: Not included are things considered ephemera (these may be discarded at will): duplicate or convenience copies of correspondence
What is a recordset and how do I use it?
When we open a recordset, the recordset itself is stored in memory and we are able to loop through the records one at a time, manipulating the data as we go. Recordsets enable us to reference field names, search for records, filter records, count records and much more. With recordsets, we can truly interact with the data stored in our databases.
What is records management?
What is Records Management? Records Management refers to the planning, budgeting, organizing, directing, training, and control involved in managing the life cycle of records in any medium. This life cycle encompasses the interrelated and interdependent phases of records creation or collection, records maintenance and use, and records disposition:
