What is an associative array?
An associative array is one of a number of array-like data structures where the indices are not limited to integers.
Single value or piece of data from the data series?
Data Point
What Is data that does not fit with the rest of the data set?
Anomalous Data
What is ungrouped data?
The ________________ of the ungrouped data is the value that most frequently appears in a set of data.
What is the sum of the data divided by the number of data values?
It is the mean average of number of collected data values.
What are the uses of sequential data access?
Sequential data is what uses access. This is used in science.
............. refers to reading and writing data consecutively?
sequential access
What are the different data access methods?
Random Access & Sequential Access
What is sequential device?
a sequential access is when one have to go though all the data to retrieve the data wanted therefore it is time consuming
What is sequential data in Access?
In Access, sequential data refers to a series of data records that are stored and organized in a specific order, based on a unique identifier or key field. This organization allows for the easy retrieval and manipulation of data in a sequential manner. Sequences in Access can be used to generate auto-incremented values for primary keys in tables.
Random access and sequential access file in vb 6.0?
To access a particular data item in a sequential file, you need to read in all items in the file prior to the item of interest. This works acceptably well for small data files of unstructured data, but for large, structured files, this process is time-consuming and wasteful. Sometimes, we need to access data in non-sequential ways. Files which allow non-sequential access are random access files.
What is the difference between direct access and sequential access?
, Both terms "direct access" and "sequential access" as you must have guessed refer to accessing schemes in the file system. In broadest sense difference between these two can be stated like this -In sequential access data is stored at random locations. -In direct access data is stored at sequential locations. ( Ironically this is true No matter what kind of first impression we get when we hear it for the first time. ) -In sequential access addition of data is fast but retrieval of data is slow. -In direct access addition of data is slow as reordering of data blocks may be needed to put current data block after the last used data block for the file. But retrieval of data is fast. -Data structure implementing Sequential access is linked list. -Data structure implementing Direct access is an Array. Application areas:- A situation where rate of addition of data is much larger compared to retrieval of data Sequential access is preferred, in opposite situation Direct access is more suitable. Regards, Prime There are technical explanations as to how it works, but in simple terms, direct access means going straight to the record you want, whereas sequential access means going through all records one by one until you find the one you want.
What storage requires sequential access of data?
magnetic disc
What are sequential access files?
The file(s) (data) which are accessed in a sequential or a orderly manner is called as a sequentially accessing a file.
What type of storage requires sequential access to locate data and information?
a tape
Differentiate between Direct Access and Sequential Access methods?
the difference between them is that direct access, such as a DVD allows you to go directly to a specific piece of data using an index, whereas sequential access is when data is chronologically stored on a VCR tape or Magnetic tape, you must go through all the data before you reach the data your looking for.
What is a indexed sequential file?
An indexed sequential file is a type of file organization where data records are stored sequentially in the order of key values. An index is maintained to help locate records quickly. This combination of sequential storage and indexing allows for efficient access to data in both sequential and random access patterns.
