3 Your Computer Is Like a Kitchen

4 Three Parts of Your Kitchen 1.Your refrigerator. 2.Your stove. 3.Your sink. You probably have more stuff than this, but almost every kitchen in the world has at least these three things.

5 The Fridge! Where you hold your food until you are ready to cook or eat it... or until the food starts turning into a new life form.Where you hold your food until you are ready to cook or eat it... or until the food starts turning into a new life form. The key measurement of a refrigerator is how much food it can hold... its storage capacity.The key measurement of a refrigerator is how much food it can hold... its storage capacity.

10 Law of Diminishing Returns Is a four burner stove twice as good as a two burner stove? (Maybe... it depends on how much you cook).Is a four burner stove twice as good as a two burner stove? (Maybe... it depends on how much you cook). Is a 16 burner stove four times as good as a four burner stove? (Heck no... who needs SIXTEEN burners?).Is a 16 burner stove four times as good as a four burner stove? (Heck no... who needs SIXTEEN burners?). The key is to find a balance between how much you have to cook and how many burners you have.The key is to find a balance between how much you have to cook and how many burners you have.

14 So How Can You Increase Your Water Pressure? GET BIGGER PIPES!

15 Three Parts Revisited 1.Your refrigerator, where you store food until you need it 2.Your stove, where you cook your food 3.Your sink, where water flows into your kitchen

16 What on Earth Does This Have to Do with My Computer? A lot, actually... So go ahead and ask……

17 Three Parts of a PC 1.Your hard drive 2.Your RAM 3.Your Internet connection You have more stuff than this, but these are the three most important things to know about... theyre the stuff you can easily change

18 Your Hard Drive Your hard drive is the computer equivalent of your refrigerator.

19 Your Hard Drive Where you hold your programs, folders, files, data, and other stuff until you are ready to use themWhere you hold your programs, folders, files, data, and other stuff until you are ready to use them The key measurement of a hard drive is how much stuff it can hold... its storage capacity.The key measurement of a hard drive is how much stuff it can hold... its storage capacity.

26 Remember... Your stove is measured by how many things it can cook at once – its size. The same is true for RAM.Your stove is measured by how many things it can cook at once – its size. The same is true for RAM. The key measurement of RAM is how big it is... how many things it can cook at once... its size (measured in megabytes.)The key measurement of RAM is how big it is... how many things it can cook at once... its size (measured in megabytes.)

27 Your Internet Connection Your Internet Connection is the computer equivalent of your kitchen sink (water pressure) Your Internet Connection is the computer equivalent of your kitchen sink (water pressure)

28 Your Internet Connection The key measurement of your Internet connection is how fast you can get stuff off of the Net... its speed (or bandwidth.) The key measurement of your Internet connection is how fast you can get stuff off of the Net... its speed (or bandwidth.)

29 Three Parts of Your PC 1.Your hard drive, which is like your refrigerator (it holds stuff) 2.Your RAM, which is like your stove (it cooks stuff) 3.Your Internet connection, which is like your sink (its your access to the stream)

30 HD Increases Storage? Will getting a bigger hard drive increase the amount of stuff (programs, documents, pictures, and so on) you can store on your computer?Will getting a bigger hard drive increase the amount of stuff (programs, documents, pictures, and so on) you can store on your computer? YepYep

31 Your Hard Drive Is Just Storage Space... A place to keep your stuff until you need it.

32 HD Increases PC Speed? Will getting a bigger hard drive increase the speed at which you can cook stuff on your computer? In other words, will it speed up your computer?Will getting a bigger hard drive increase the speed at which you can cook stuff on your computer? In other words, will it speed up your computer? NO!NO!

33 Getting a Bigger Hard Drive Will NOT Speed Up Your Computer... any more than getting a bigger refrigerator will speed up your cooking times. All your hard drive does is store stuff.

34 HD Increases Net Speed? Will getting a bigger hard drive increase the speed at which you can access, or download stuff off of, the Internet?Will getting a bigger hard drive increase the speed at which you can access, or download stuff off of, the Internet? NO!NO!

35 Getting a Bigger Hard Drive Will NOT Speed Up Your Net Connection... any more than getting a bigger refrigerator will speed up your sink. All your hard drive does is store stuff.

36 Everyone With Me? 1.Your hard drive, which is like your refrigerator (it holds stuff) 2.Your RAM, which is like your stove (it cooks stuff) 3.Your Internet connection, which is like your sink (its your access to the stream)

37 RAM Increases Storage? Will getting more RAM increase the amount of stuff you can store on your hard drive?Will getting more RAM increase the amount of stuff you can store on your hard drive? NO!NO!

38 Getting More RAM Will NOT Help You Store More Files on Your Computer... it will only help you run more computer programs (like Microsoft Word, Solitaire, and so on) simultaneously.

39 RAM Increases PC Speed? Will getting more RAM increase the speed at which you can cook stuff on your computer? In other words, will it speed up your computer?Will getting more RAM increase the speed at which you can cook stuff on your computer? In other words, will it speed up your computer? Maybe, but only to a point.Maybe, but only to a point.

40 Remember This? How many things can you cook at once on this stove? (Four)How many things can you cook at once on this stove? (Four) What would happen if you had to cook more than four things at once? (It would take a LOT longer to cook because youd have to constantly swap pots.)What would happen if you had to cook more than four things at once?

If you have Windows NT, 2000, or XP, get 256 Megabytes of RAM.If you have Windows NT, 2000, or XP, get 256 Megabytes of RAM. Get more ONLY if you work with videos, pre- press graphics, or advanced games.Get more ONLY if you work with videos, pre- press graphics, or advanced games.

45 Hard Drives v. RAM If you run out of storage space on your hard drive, you need to either delete some files or get a second (or a bigger) hard drive.If you run out of storage space on your hard drive, you need to either delete some files or get a second (or a bigger) hard drive. If you keep getting out of memory errors or want to run a bunch of programs at once, you need to get more RAM.If you keep getting out of memory errors or want to run a bunch of programs at once, you need to get more RAM.

46 RAM Increases Net Speed? Will getting more RAM increase the speed at which you can access, or download stuff off of, the Internet?Will getting more RAM increase the speed at which you can access, or download stuff off of, the Internet? NO!NO!

47 Getting More RAM Will NOT Speed Up Your Net Connection... any more than getting a bigger stove will speed up your sink.
