Answer:
ATMs: When you insert a credit card or debit card into the machine, it reads account information encoded on the card’s magnetic strip. The ATM forwards your account details to a host processor that directs the transaction request to the bank that issued the card. When you request funds, the host processor transfers funds electronically from the cardholder’s bank account to the host processor account. The host processor then sends an approval code to the ATM machine, authorizing it to dispense the funds.
Vending machines: Most vending machines accept both paper bills and coins as payment for items. They pull in paper bills using rollers. Once the bills are inside the machine, scanners detect their denominations and set them aside in a cash box. The machine identifies the denomination of coins through their physical characteristics. For example, the machine detects that a quarter is .955 inches in diameter, 1.75 millimeters thick, and has 119 ridges around its edge.
Game consoles: Game consoles are specialized computers that users can connect to television sets to play video games. Recent advancements in technology enable developers to immerse players deeper into the games. Using motion control sensors, players can physically manipulate visual overlays and objects in the game’s world. Introducing such a physical aspect also encourages creativity in design.
Microwave ovens: The microwave oven saves cooking time by heating food quickly. The heat transfer between food molecules occurs starting with the outer layers first. This transfer continues until the heat evenly distributes among all the molecules. Microwave cooking differs from conventional cooking methods. In microwave ovens, food cooks from the inside out. Microwave radiation excites water molecules in the food. This increases the molecules’ energy levels, causing them to collide with each other. The collisions generate heat.
