Representation of a FIFO queue. In computing and in systems theory, first in, first out (the first in is the first out), acronymized as FIFO, is a method for organizing the manipulation of a data structure (often, specifically a data buffer) where the oldest (first) entry, or "head" of the queue, is processed first.
The use of FIFO is a response to the precarity of resource extraction sectors: the workers can be shipped in quickly during resource booms and sent away during busts. [4] Usually, a fly-in fly-out job involves working a long shift (e.g., 12 hours each day) for a number of continuous days with all days off spent at home rather than at the work site.
A backup rotation scheme is a system of backing up data to computer media (such as tapes) that minimizes, by re-use, the number of media used.The scheme determines how and when each piece of removable storage is used for a backup job and how long it is retained once it has backup data stored on it.
The operations of a queue make it a first-in-first-out (FIFO) data structure. In a FIFO data structure, the first element added to the queue will be the first one to be removed. This is equivalent to the requirement that once a new element is added, all elements that were added before have to be removed before the new element can be removed.

While it is sometimes used interchangeably, inventory management and inventory control deal with different aspects of inventory. Inventory management is a broader term pertaining to the regulation of all inventory aspects, from what is already present in the warehouse to how the inventory arrived and where the product's final destination will be.

FIFO treats the first unit that arrived in inventory as the first one sold. LIFO considers the last unit arriving in inventory as the first one sold. Which method an accountant selects can have a significant effect on net income and book value and, in turn, on taxation.
FIFO and LIFO accounting are methods used in managing inventory and financial matters involving the amount of money a company has to have tied up within inventory of produced goods, raw materials, parts, components, or feedstocks. They are used to manage assumptions of costs related to inventory, stock repurchases (if purchased at different ...
