9. Which one of the following explains the sequential file access method? Explanation: None.Sequential Access to a data file means that the computer system reads or writes information to the file sequentially, starting from the beginning of the file and proceeding step by step. On the other hand, Random Access to a file means that the computer system can read or write information anywhere in the data file.A common example of sequential access is with a tape drive, where the device must move the tape’s ribbon forward or backward to reach the desired information. The opposite would be RAM (Random Access Memory) going anywhere on the chip to access the information.
What is file access sequential?
Sequential Access to a data file means that the computer system reads or writes information to the file sequentially, starting from the beginning of the file and proceeding step by step. On the other hand, Random Access to a file means that the computer system can read or write information anywhere in the data file.
Which is the example of accessing through sequential method?
A common example of sequential access is with a tape drive, where the device must move the tape’s ribbon forward or backward to reach the desired information. The opposite would be RAM (Random Access Memory) going anywhere on the chip to access the information.

What are file access methods?
Modern word systems do provide the concept of direct access and indexed access but the most used method is sequential access due to the fact that most of the files such as text files, audio files, video files, etc need to be sequentially accessed.
Which is sequential access device?
A sequential-access storage device is one in which arrival at a desired storage location is preceded by sequencing through other locations so that access time various according to location. That is, we can retrieve information stored on a sequential-access device only in the same sequence in which it is stored.
What is sequential access file in C?
A sequential access file is such that data are saved in sequential order: one data is placed into the file after another. To access a particular data within the sequential access file, data has to be read one data at a time, until the right one is reached.
What is sequence access method?
Sequential Access –
It is the simplest access method. Information in the file is processed in order, one record after the other. This mode of access is by far the most common; for example, editor and compiler usually access the file in this fashion.
What is sequential access method in computer?
In computing, sequential access memory (SAM) is a class of data storage devices that read stored data in a sequence. This is in contrast to random access memory (RAM) where data can be accessed in any order. Sequential access devices are usually a form of magnetic storage or optical storage.

What are the sequential accessing methods in data structures?
Sequential Access means that a group of elements (e.g. data in a memory array or a disk file or on magnetic tape data storage) is accessed in a predetermined, orderedsequence. Sequential access is sometimes the only way of accessing the data, for example if it is on a tape.

What is random access and sequential access?
The terms random access and sequential access are often used to describe data files. A random-access data file enables you to read or writeinformation anywhere in the file. In a sequential-access file, you can only read and write information sequentially, starting from the beginning of the file.
What is a file access?
A file access definition can control access to data in specified tables and columns, or to tables and columns for which access is not granted explicitly. You define access permissions by creating an access list for a table, column, or the default.

Which memory allows only sequential access of data and the write operation of data can be performed only once?
Detailed Solution. The correct answer is Magnetic tape. Magnetic tape is a secondary storage device used for storing files of data. Access is sequential and consists of records that can be accessed one after another as the tape moves along a stationary read-write mechanism.
