Why use process statement in vhdl?
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.

What is a Sequential fall?
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.
What are the differences between direct access and random access?
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
Which Access component is best for data presentation?

What is the disadvantage of sequential file organization?
One disadvantage of sequential file organization is that it can be slow for locating and accessing specific records, as the entire file must be scanned sequentially from the beginning to find the desired data. Additionally, inserting or deleting records in a sequential file can be inefficient and may require reorganizing the entire file.
Which storage media provides sequential access only?
magnetic tape

What are the uses of sequential data access?

Full form for HSAM?
Hierarchical Sequential Access Method-is a method to use sequential access of database.
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 are the different data access methods?
Random Access & Sequential Access
What requires sequential access?
TAPE!
What are the techniques of file processing?
The common techniques of file processing include sequential access, random access, and direct access. Sequential access involves reading data sequentially from the beginning to the end of a file. Random access allows reading data from any part of the file without having to read the preceding data. Direct access uses a key or address to locate specific data within the file.
What are the advantages and disadvantages sequential access?
Advantages of sequential circuits
What is sequential databse?
Sequential data is when things are stored and accessed in order, starting from the beginning (or end) of the file. So to access a given record, you would have to access everything before that point. Sometimes this is the only way to access things, such as items stored on tape.
