Almost all programming languages are sequential in nature. But VHDL is a concurrent language. In an architecture for an entity, all statements are concurrent. So where do sequential statements exist in VHDL?. There is a statement called the process statement that contains only sequential statements. The process statement is itself a concurrent statement. A process statement can exist in an architecture and define regions in the architecture where all statements are sequential. A process statement has a declaration section and a statement part. In the declaration section, types, variables, constants, subprograms, and so on can be declared. The statement part contains only sequential statements. Sequential statements consist of CASE statements, IF THEN ELSE statements, LOOP statements, and so on.

In a fall arrest system, typically a horizontal lifeline, a sequential fall occurs when two or more workers are connected to the same span of the horizontal lifeline and one worker falls. His / her fall causes deflection in the lifeline which pulls off the second worker and any other workers connected to the lifeline.
Direct access means going straight to the record you want,and random access means pick data randomly and then find that data which you required.http://wiki.answers.com/Difference_between_direct_and_sequential_access#ixzz1685bfqda

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.

give the examples of sequential access memory?
sequential access
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.
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.
Sequential data is what uses access. This is used in science.
Hierarchical Sequential Access Method-is a method to use sequential access of database.
Random Access & Sequential Access
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.
