  1. What is file organization? Answer: File organization refers to the way data is arranged and stored in a computer system. What are the advantages of sequential file organization? Answer: Sequential file organization is simple and requires the least amount of storage space. What are the disadvantages of sequential file organization? Answer: Sequential file organization is not suitable for storing data that needs to be accessed randomly. What is direct file organization? Answer: Direct file organization allows data to be accessed using its physical location on the storage medium. What is indexed file organization? Answer: Indexed file organization allows data to be accessed using a key value. What are the advantages of indexed file organization? Answer: Indexed file organization allows for faster access to data and supports both sequential and random access. What are the disadvantages of indexed file organization? Answer: Indexed file organization requires more storage space compared to sequential file organization. What is hashed file organization? Answer: Hashed file organization allows for faster access to data by using a hash function. What are the advantages of hashed file organization? Answer: Hashed file organization provides the fastest access to data and requires less storage space compared to indexed file organization. What are the disadvantages of hashed file organization? Answer: Hashed file organization is more complex and requires additional processing time to compute hash values.

File organization is a crucial aspect of database management. It refers to the way data is stored and organized in a computer system. There are different types of file organization, each with its own advantages and disadvantages. Sequential file organization stores data in a sequential manner, meaning data is stored one after the other. This method is simple and requires the least amount of storage space. However, it is not suitable for storing data that needs to be accessed randomly. Direct file organization, on the other hand, allows data to be accessed using its physical location on the storage medium. This means that data can be accessed randomly, making it ideal for systems that require frequent random access to data. Indexed file organization allows data to be accessed using a key value. This makes it faster to access data compared to sequential file organization, and it supports both sequential and random access. However, it requires more storage space compared to sequential file organization. Hashed file organization allows for faster access to data by using a hash function. It provides the fastest access to data and requires less storage space compared to indexed file organization. However, it is more complex and requires additional processing time to compute hash values. Choosing the appropriate file organization for a system depends on various factors, such as the amount of data, the frequency of data access, and the type of data being stored. Understanding the advantages and disadvantages of each file organization is essential in selecting the most suitable one for a particular system.
