Introduction For the past several decades, due to the development of computers and other electronic systems, doing business has become much easier than before. Information technologies have allowed making important business calculations much faster and more accurate. Particularly, inventory management systems are special software and hardware used for tracking orders, deliveries and sales, inventory levels, and other documents related to production. They also allow companies to organize data that was previously stored in the form of spreadsheets. Thus, to make this system work, the special electronic equipment and people who will operate it are needed. The Required Equipment The main purpose of inventory systems is to control inventory levels, thereby reducing the possibility of overstock or understock situations. To increase efficiency and accuracy in handling inventories, most businesses use barcode technology. The barcode reads at the cash register, while the data of inventory sales transmit the information to a wider system that calculates the statistics. Companies use this information when they are going to buy a certain product taking into account inventory levels and sales. Additionally, barcode technologies are capable of handling inventory at the warehouses level. Warehouses usually utilize radio frequency identification (RFID) to scan newly come inventory and add it to the warehouse system software (Emerson, 2017). Thus, the basic hardware equipment that uses barcode technologies and is required for successful inventory management includes a desktop PC, laptop, router, barcode scanner, barcode printer, fax, and mobile devices. Thus, the first device my sister would need in her business is a desktop PC or a laptop. Nowadays, it is more common to use laptops rather than desktop PCs, as they are more mobile. However, in inventory management, it will not likely to be moved frequently, that is why it does not matter what to choose. This device will allow my sister to control her sales and inventory levels (“Hardware inventory,” 2016). Also, this device should have wireless access. The second important device, which will improve my sister’s inventory management, is a wireless router. It can create a private computer network and connect it to the internet. Thus, having all devices connected to one network will allow the fast and accurate transfer of information concerning inventory management, which, in turn, will increase the company’s performance by several times. The third device required for successful inventory management is a barcode scanner. A barcode scanner is an electronic device that reads and transfers printed barcodes to a laptop or PC. This device will allow my sister to significantly reduce the time needed for organizing inventory. Without this device, employees have to spend too much time organizing the inventory, which considerably decreases the overall efficiency of a company. The next device required for managing inventory levels is a barcode printer (“Hardware inventory,” 2016). It is a device used for printing barcode tags and labels that can be attached either on different objects directly or on items made of special materials that are stuck to various inventory devices. Another device needed for handling inventory levels is fax. Despite being relatively outdated and ousted by Internet device
