Blown to bits chapter 1

The smallest unit of information in computer

• Byte

• Bit

• Pixel

• it's too small I can't see it

Computer creates the illusion that it contains photographs, letters, songs, movies...

• It's all just bits

• Perfection is normal

• More of the same can be a whole new thing

• Bits move faster than thought

Networks check to make sure that bits are transferred correctly.

• Error Detection and Return

• File received in error

• Error Detection and Correction

Gordon Moore, founder of Intel observed

• internet is getting faster and faster

• computer applications cannot keep up with computers

• density of circuits seems to double every year

• we need more computer science majors

The fastest computers available in the 1940s could perform about 1000 operations per second

• True

• False

• Huh

Moore's Law states

• Computers become faster every 2 years

• the market cannot keep up with technolgy

• you don't need a computer science degree to program

Computer power has experienced exponential growth

• Perfection is normal

• Bits move faster than thought

• More of the same can be a new thing

• There is want in the midst of plenty

Data will all be kept forever, unless there are policies to get rid of it.

• There is want in the midst of plenty

• Nothing goes away

• It's all just bits

• Perfection is normal

The instantaneous communication of massive amounts of information and where it is stored

• Network Drives

• Cloud

• Cyberspace

• Floppy Disks

A list of parties to whom services are available, with everyone else excluded.

• White list

• Black list

• What list?

• Can I be on the list?
