The typical process is: You enter a command to ping a destination. DNS is used to determine the IP address (if needed). The routing table is consulted to find the next hop towards that destination. ARP is used to find the hardware address of the next hop.
It is claimed that certain foods and drinks can boost your metabolism, including green tea, black coffee, spices and energy drinks. The evidence behind these claims is flimsy, the effect on your metabolism is marginal at best and each person will respond differently to each product.
The best way to speed up your metabolism is to drink a lot of water. Drink a glass of water as soon as you get up from bed and don't eat after it for 30 mins, also drink a whole glass of water before each meal BUT don't drink water right after meals, give yourself at least 1 hour after meal before drinking any fluid.
