5-*
Learning Objectives

5-*
Learning Objectives
- Consider the managerial implication of faster and cheaper computing on areas such as strategic planning, inventory, and accounting

5-*
Learning Objectives

Some Definitions
- Moore’s Law: Chip performance per dollar doubles every eighteen months
- Microprocessor: The part of the computer that executes the instructions of a computer program
- Random-access memory (RAM): The fast, chip-based volatile storage in a computing device
- Volatile memory: Storage (such as RAM chips) that is wiped clean when power is cut off from a device
- Nonvolatile memory: Storage that retains data even when powered down (such as flash memory, hard disk, or DVD storage)
5-*
Some Definitions
- Flash memory: Nonvolatile, chip-based storage, often used in mobile phones, cameras, and MP3 players
- Solid state electronics: Semiconductor-based devices
- Semiconductors: A substance such as silicon dioxide used inside most computer chips that is capable of enabling as well as inhibiting the flow of electricity
- Optical fiber line: A high-speed glass or plastic-lined networking cable used in telecommunications

Get Out Your Crystal Ball
- When technology gets cheap, price elasticity kicks in
- The five waves of computing over the previous five decades:
- 1960s – Mainframe computers
- 1970s – Minicomputers
- 1980s – PCs
- 1990s – Internet computing
- Present – Ubiquitous computing
5-*
Ambient Devices and the Fifth Wave
- Ambient Devices is a “fifth wave” firm that’s embedding computing and communications devices into everyday products to make them more useful and smarter
- Ambient’s ability to pull off this little miracle is evidence of how quickly new markets, spawned by Moore’s Law, can come into being
- Ambient has expanded the product line to several low-cost appliances designed to provide information at a glance
5-*
Get Out Your Crystal Ball
- One of the most agile surfers of this fifth wave is Apple, Inc,
- A firm with a product line that is now so broad that in January 2007, it dropped the word “Computer” from its name
- The high-end iPod increased song capacity by forty times in six years while dropping in cost by fifty dollars
- The change in hard drive prices isn’t directly part of Moore’s Law, the faster and cheaper phenomenon applies to storage
- Example: Amazon
5-*
Bits and Bytes
- Computers express data as bits that are either one or zero
- Eight bits form a byte
- A kilobyte refers to roughly a thousand bytes, or a thousand characters
- Megabyte = 1 million
- Gigabyte = 1 billion
- Terabyte = 1 trillion
- Petabyte = 1 quadrillion
- Exabyte = 1 quintillion bytes
5-*
Bits and Bytes
- Storage is listed in bytes
- Telecommunication capacity (bandwidth) is listed in bits per second (bps)

Bytes Defined

Get Out Your Crystal Ball
- If you are producing products with a significant chip-based component, the chips inside that product rapidly fall in value
- It is great when it makes your product cheaper and opens up new markets for your firm
- It can be deadly if you overproduce and have excess inventory sitting on shelves for long periods of time
- Moore’s Law impacts mundane management tasks too
5-*
The Death of Moore’s Law?
- Moore’s Law is possible because the distance between the pathways inside silicon chips gets smaller with each successive generation
- Since the pathways are closer together, electrons travel shorter distances
- If electrons travel half the distance to make a calculation, that means the chip is twice as fast
- This shrinking can’t go on forever
- Three interrelated forces—size, heat, and power—threaten to slow down the Moore’s Law gravy train
5-*
The Death of Moore’s Law?
- Microsoft, Yahoo!, and Google have all built massive data centers in the Pacific Northwest in order to benefit from cheap hydroelectric power
- The chief eco officer at Sun Microsystems has claimed that computers draw four to five percent of the world’s power
- Google’s chief technology officer has said that the firm spends more to power its servers than the cost of the servers themselves
- Chips can’t get smaller forever because chip pathways can’t be shorter than a single molecule and actual physical limit may be higher
5-*
Buying Time
- Multicore microprocessors: Microprocessors with two or more (typically lower power) calculating processor cores on the same piece of silicon
- For many applications, the multicore chips will outperform a single speedy chip, while running cooler and drawing less power
- Multicore processors are now mainstream
- Today, most PCs and laptops sold have at least a two-core (dual-core) processor
- In 2010, Intel began shipping PC processors with eight cores, while AMD introduced a 12 core chip
5-*
Buying Time
- Multicore processors can run older software written for single-brain chips
- They usually do this by using only one core at a time
- In order to take full advantage of multicore chips, applications need to be rewritten to split up tasks so that smaller portions of a problem are executed simultaneously inside each core
- Writing code for execution in a multicore environment is challenging
5-*
Buying Time
- Another approach to extending the life of Moore’s Law is using stacked or three-dimensional semiconductors
- Semiconductors that are manufactured as a stack of multiple, interconnected layers instead of in one flat plane
- In this approach, a flat chip is sliced into pieces, and then the pieces are reconnected vertically, thus making a sort of “silicon sandwich”
- The chips are both faster and cooler since electrons travel shorter distances

Bringing Brains Together: Supercomputing and Grid Computing
- Supercomputers: Computers that are among the fastest of any in the world at the time of their introduction
- Supercomputing was once the domain of governments and high-end research labs
- Modern supercomputing is done via massively parallel processing
- Massively parallel: Computers designed with many microprocessors that work together, simultaneously, to solve problems
5-*
Bringing Brains Together: Supercomputing and Grid Computing
- Grid computing: A type of computing that uses special software to enable several computers to work together on a common problem as if they were a massively parallel supercomputer
- Multicore, massively parallel, and grid computing are all related in that each attempts to lash together multiple computing devices so that they can work together to solve problems
5-*
Bringing Brains Together: Supercomputing and Grid Computing
- The dark side to Moore’s Law is discarded tech junk, referred to as electronic waste or e-waste
- e-waste: Discarded, obsolete technology
- Recycling is a solution to the problem
- E-waste contains mainstream materials like aluminum and plastics as well as more valuable materials like gold, silver, platinum, and copper
5-*
Bringing Brains Together: Supercomputing and Grid Computing
- There is a disconnect between consumers and managers who want to do good and those efforts that are actually doing good
- The following points show how difficult addressing this problem will be
- The complexities of the modern value chain
- The vagaries of international law
- The nefarious actions of those willing to put profits above principle
- The process of recycling is extremely labor intensive
- Disregard of ethical recycling imperatives can tarnish a brand
