Sequential access basically means accessing things one after the other in order. For example reading all the numbers from 1 to 10 by starting at 1, then 2, then 3 etc.

Complexity of sequential search?
The simplest and slowest searching method; the only possible method when the data is unsorted and/or only sequential access is possible (eq. processing a tape file). I think he's looking for time complexity which I believe is just n
Difference between direct sequential file and index sequential file?
Explain the difference between sequential and direct file access.A. Sequential access to data is used when the data has to be read from the start, in sequence. It is the normal method of access for magnetic tape. Direct access is used when it is possible to jump directly to a file or data item without reading through all the items stored before it. This is the normal method used for hard disks.
What is Disk On Chip?
Disk on Chip is a non-volatile memory which has overcome the disadvantage of nand flash memory The difference is that NAND FLASH Access Method : Sequential Ease of use : Complex Easy Here memory management is highly complex not reliable DOC Access Method : Random For Code Sequential for data Ease of use : With help of TrueFFS Its pretty good and Highly reliable For more info go to M-systems Site:
What is meant by private visibilty of a method?
It means that the method is visible from only within the current method. Also, any class that wants to use or invoke the private method has to create an object of the class in which the method is created in order to access/invoke it. The private access modifier is the most restrictive of the four java access modifiers. The total opposite of private is public which gives access to everyone.
It is perfectly legal to any instance variable inside of a static method?
No. You will get compilation errors. The complier will complain that you are trying to access non static variables from inside a static method. A static method can access only static variables.
Full form for HSAM?
Hierarchical Sequential Access Method-is a method to use sequential access of database.
What is the access method for floppy diskette?
A cool one
What are two basic types of record access method?
sequential and indexed
What is the access method of magnetic tape?
It's sequential (or serial) access. The records are written one after the other (as if in a line or queue) and in order to find one the tape must be fast-forwarded or rewound as appropriate until the beginning of the record is found.

File accessing techniques in data management system?
Information is kept in files. Files reside on secondary storage. When this information is to be used, it has to be accessed and brought into primary main memory. Information in files could be accessed in many ways. It is usually dependent on an application.Sequential Access: A simple access method, information in a file is accessed sequentially one record after another. To process the with record all the 1-1 records previous to 1 must be accessed. Sequential access is based on the tape model that is inherently a sequential access device. Sequential access is best suited where most of the records in a file are to be processed. For example, transaction files.Direct Access: Sometimes it is not necessary to process every record in a file. It may not be necessary to process records in the order in which they are present. Information present in a record of a file is to be accessed only if some key value in that record is known. In all such cases, direct access is used. Direct access is based on the disk that is a direct access device and allows random access of any file block. Since a file is a collection of physical blocks, any block and hence the records in that block are accessed. For example, master files. Databases are often of this type since they allow query processing that involves immediate access to large amounts of information. All reservation systems fall into this category. Not all operating systems support direct access files. Usually files are to be defined as sequential or direct at the time of creation and accessed accordingly later. Sequential access of a direct access file is possible but direct access of a sequential file is not.Indexed Sequential Access: This access method is a slight modification of the direct access method. It is in fact a combination of both the sequential access as well as direct access. The main concept is to access a file direct first and then sequentially from that point onwards. This access method involves maintaining an index. The index is a pointer to a block. To access a record in a file, a direct access of the index is made. The information obtained from this access is used to access the file. For example, the direct access to a file will give the block address and within the block the record is accessed sequentially. Sometimes indexes may be big. So hierarchies of indexes are built in which one direct access of an index leads to info to access another index directly and so on till the actual file is accessed sequentially for the particular record. The main advantage in this type of access is that both direct and sequential access of files is possible.
How does sequential access work in a tape drive?
Sequential access is a method of data access used by tape drives, whereby data is written or read sequentially from the beginning to the end of the tape or until the desired data is found. Basically, in order to read data from anywhere on a tape, you must start at the beginning of the tape and read until you come to the "sought-after" data.

Where do you define the access specifier for a java method properties?
We define the access specifier of a function at the place of its method signature(The place we write the method's name).for example,public void sample(){}here "public" is the access specifier of function name-sample.
What are the disadvantages of random access?
Assuming you're talking about tape storage.. mainly speed ! With sequential access, the medium has to be constantly rewound back to the start before the next relevant data can be accessed. The constant rewinding slows down the access time.
File oriented system vs database oriented system?
A file-oriented system organizes data in separate files without any relationship between them, leading to data redundancy and inconsistency. In contrast, a database-oriented system uses a centralized database management system to store and manage data, ensuring data integrity, security, and efficient access through the use of relational tables and queries.
