Data Structures Advantages and Disadvantages

  • The advantages of data structure The data structure enhances the storage device's data storage efficiency. Its use of structure facilitates data retrieval from a storage media. It can successfully and efficiently handle both little and large amounts of data. The majority of well-organized data structures, such as arrays, stacks, queues, graphs, trees, and linked lists, have well-built and pre-planned techniques for storage, retrieval, manipulation, and deletion. When employing these data structures, the programmer can completely trust them.
  • Data structure's disadvantages Using complex data structures to manage a huge amount of data can impose a high overhead on the CPU. This is because, in order to access any piece of data, a lot of work is done by the CPU.  The more complex the structure is, the more overhead will be imposed on the CPU, and thus, memory consumption increases as well. The size of space required in memory can be beyond our calculations if we are not careful in choosing appropriate data structures and algorithms to deal with data.
