Storage methods

As you have learned, you lose any program and data stored in RAM when you turn off the computer. The only way to save a program and data is to store them externally — that is, outside the computer. The main form of external storage are disks. Once you've stored data externally, you can load

it back into RAM.

Cartridge

A cartridge is a small plastic box that contains a permanent program, somewhat like ROM. The box, about the size of a pocket calculator, plugs into a slot in a microcomputer. Cartridges are often called ROM cartridges because they have read-only memory. As a user, you cannot store anything new on a cartridge. You can only use what is put there by the manufacturer.

Cartridges are fully enclosed andsturdy.Forthatreason.computer games are often put on cartridges. Not all microcomputers accept cartridges

Hard disk

A hard disk is a round, pancake-shaped, permanently sealed magnetic storage device. Sizes vary, but one common size is about the diameter of a 33 rpm record. Hard disks accept a great deal of information. A single hard disk can store many more times as much materials as a 5ghsdfgh - inch floppy disk.

Since hard disks are encased in rigid plastic, they are less likely to be damaged than are the somewhat fragile floppies. Hard disks are used mainly with mainframes and minicomputers although they can be used with many microcomputers. Their biggest advantage is their great storage capacity.

Hard disk drive units, as you might expect, are expensive but, as with all computer hardware, their price is going down.

What? how? who?

In an earlier chapter we learned that every society must provide answers to the same three questions: What goods and services will be produced? How will those goods and services be produced? Who will receive them? We also learned that different societies and nations have created different economic systems to provide answers to these fundamental questions. Traditional economies look to customs and traditions for their answers. Others, known as command economies, rely upon governments to provide the answers. In free enterprise systems, market prices answer most of the What, How and Who questions.

Because market prices play such an important part in free enterprise systems, those systems are often described as "price-directed market economies." In this chapter you will learn about the forces that determine what prices will be — supply and demand. Prices In A Market Economy

Prices perform two important economic functions: They ration scarce resources, and they motivate production.

As a general rule, the more scarce something is, the higher its price will be, and the fewer people will want to buy it. Economists describe this as the rationing effect of prices. In other words, since there is not enough of everything to go around, in a market system goods and services are allocated, or distributed, based on their price. Did you ever attend an auction, or see one conducted on TV? What you saw was the rationing effect of prices in action. The person leading the sale (the "auctioneer") offered individual items for sale to the highest bidder. If there was only one item, it went to the single highest bidder. If there were two items, they went to the two highest bidders, and so on.

Price increases and decreases also send messages to suppliers and potential suppliers of goods and services. As prices rise the increase serves to attract additional producers. Similarly, price decreases drive producers

out of the market. In this way prices encourage producers to increase or decrease their level of output. Economists refer to this as the production-motivating function of prices.
