Linked list structures can be designed in a variety of ways. Each has its own advantages and disadvantages. For this reason, many computer scientists use a combination of both directed and unlinked list designs to achieve better results in their computations.
Directed linked lists work best when there are a few elements in the set. The elements are placed in a specific order, and the entire structure is marked by an object link between them. In unlinked lists, however, the order of the elements is not specified, and so the elements themselves have no link. They point directly to other elements and can be arranged in any order.
Linked lists are often used for finding a path between two or more points in a set. If there are a lot of nodes and links between them, this may prove difficult. Linked lists allow users to specify a particular order, thereby making the path more manageable.
Linked lists are often used to store a large amount of data. They may contain all or part of an array, or they may store a series of numbers in a format that is easy to manipulate. Some of these lists can even store large amounts of information in a compact way.
Linked lists can be used to simulate virtual worlds. These virtual worlds may contain multiple copies of the same object. In this case, the user can place each copy in a different link and have each link point to its neighbour. Because the links are not linked, however, users may choose to have different objects appear at different times, in the same order.
Linked lists are also used to simulate the linking of multiple files on a hard disk. In some situations, a hard drive is so large that it makes it impractical to simulate a link from one file to another. If the user wants to create a replica of his or her file without actually deleting it, this is sometimes possible.
Linked lists are still a viable option today, despite their limited use. In addition to helping people find their way between nodes, they can also be useful for finding links to different parts of a database.
Linked lists can also be useful in other situations. A person who works at home may be required to access certain files from several locations. With a list, a user can define a list of websites that she can go to whenever she needs to download something and can link the various files with an object link. This allows her to locate all the files she wants without having to type each URL individually.
A web site developer may use linked lists to build an archive of links that can be retrieved from any web site. whenever he or she needs to retrieve a file, and allows users to retrieve only the links they want from a central source. instead of every single link they encounter.
Linked lists are often used by search engines. They allow users to enter a phrase and narrow down a list of results so that only those files they need to see are displayed. This prevents the user from browsing hundreds of other pages.
Links on linked lists can be useful but not always reliable. Although they are easy to use, they can be inefficient when used for long term data storage. The data stored in linked lists is prone to corruption. It is important to be sure that the links on a linked list are as safe as possible.
