Relative:-
1. In this mode the content of the program counter is added to the address part of the instruction to obtain the effective addressed.
2. Effective Address = Contents of the program counter + contents of address field.
3. No extra index bit is used.
4. Example:-
EA = [ BX ] + [ SI ] + disp.
EA = [ BX ] + [ DI ] + disp.
Indexed:- 1. In this mode of addressing an attempt is made to avoid the use of two addressed for an operand.
2. Effective Address = Address field + contents of the specified - index registers.
3. In this extra index bit is used.
4. Example:-
EA = [ BX ] + [ SI ]
EA = [ BX ] + [ DI ]

Advantages of indexed sequential file organisation?
Indexed sequential file organization offers advantages such as fast access to records through the use of an index, which allows for efficient retrieval of data. It also provides sequential access to records, making it suitable for applications that require both sequential and random access. Additionally, indexed sequential files are typically more space-efficient compared to other file organization methods, as they combine the benefits of both sequential and random access structures.
What is indexed addressing mode?
When stored in contiguous blocks, data usually has a base address. Accessing any data from the block requires an offset to the base address which is achieved through an index. The adding of an offset to the base address is called indexed addressing.
What is the difference between an array element and a variable?
An array element is a specific value stored within an array data structure, identified by its position or index within the array. A variable, on the other hand, is a named storage location in a program's memory that holds a value which can be changed during program execution. Arrays can store multiple elements of the same data type, while variables typically store a single value of a specific data type.
What is robots text and on what website can a person find information on this subject?
Robots text is a file you can put on your website to point search engine robots to whatever it is you want indexed on your website. You can find more information about this subject at the library.
What is onionib?
Onionib is a play on words combining "onion" and "web," referring to websites that can only be accessed through the Tor anonymity network. These websites are part of the dark web, which is a small section of the deep web that is intentionally hidden and not indexed by traditional search engines. Onionib sites often contain illicit or sensitive content and are accessed using special browsers like Tor Browser.
What is the 3 diff methods of organizing file?
Sequential, Relative, Indexed.
What is the difference between the file maintenance and file organization?
file organization is of 3 types sequential,direct and indexed sequential where how data is accessed in eash file is decided where as file maintainence is
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.
What are two basic types of record access method?
sequential and indexed
Implementation of index sequential file organization?
Indexed sequential file organization. =In indexed sequential file organization, the records arestored in sequence according to a primary key and an index is created to allow random access of the file. This type of organization also allows the file to be accessed sequentially. Indexed sequential is the most commonlyused type of file organization. writer-k.k.b -montanna

What are the advantages of indexed-sequential file organisation?
Indexed-sequential file organization allows for efficient storage and retrieval of records by combining the benefits of sequential access (fast for batch processing) and direct access (quick for individual record retrieval). It provides faster access to records compared to purely sequential files while maintaining sequential organization for improved batch processing performance. The index allows for quick access to specific records without needing to search through the entire file.
Difference between NON-vsam datasets and vsam datasets?
VSAM files are used when we want to store data based on some key fields(Eg: KSDS) access method is indexed. NON VSAM files like PS are used when we want to store data which is not unique and also the access is sequential.

What has the author F J S Edwards written?

What are the advantages and disadvantages of indexed-sequential file organization?
Well, honey, let me break it down for you. The advantage of indexed-sequential file organization is that it allows for quick access to records through the index, making retrieval faster than in sequential files. However, the downside is that maintaining the index can be a pain in the rear, especially as the file grows in size. So, it's like having a fancy sports car - it's great when it works, but it can be a headache to maintain.
What is the role of ESE in active directory?
The role of ESE in an active directory is to store and retrieve data through indexed and sequential access.Its the data storage technology from Microsoft.
