This is due to the rise of gigantic supermarkets sweeping the world and therefore it is no longer possible to track stocks and sales without the help of ICT. Computer systems are used in a variety of ways: • Inventory control software • Maintaining consistent temperatures in refrigerators and freezers • Satellite tracking systems to track delivery trucks • CCTV to monitor customer entry and exit • Electronic Scales • EPOS Systems • Computer network to connect stock control system from store to head office Supermarket Hardware Types of Hardware in Supermarkets: • CCTV Cameras • Electronic Scales • EPOS Systems • Computers • EFTPOS (Electronic Transfer Point of Sale of funds)• Automatic doorsComputersThere are rooms such as the systems office which contain several computers depending on the size and status of the supermarket.

It can also repair files and systems if they are affected by a virus. However, the software needs to be updated frequently because new viruses are constantly being created.Benefits• Free security software is available• Most free antivirus software comes with even advanced detection technologies• Free security software updates free securityDisadvantages• Some security software cannot identify sophisticated malware • Security software is capable of significantly slowing down computer performance as it scans.
