A discussion of current information technology and future trends. The content is designed for a broad audience that wants to know what is happening but does not want to spend all their waking hours trying to keep up.
If you been searching for the fountain of youth, the pot of gold at the end of the rainbow or a way to run Microsoft Office on a tablet, be careful what you wish for. There are now several ways to run full versions of Office on an iPad. I've tried OnLive and CloudOn and they were both easy to install and easy to use and worked like Windows/Office would work with a ten inch screen, virtual keyboard, no mouse and a moderate speed Internet connection - not very well actually.
Imagine creating an Excel spreadsheet or PowerPoint presentation on a very small screen. Functionally they seemed to work since you are using full Office applications in the cloud. The tablet is a dumb terminal as old timers would say. If you were to develop a great PowerPoint presentation in your office with a fast Internet connection and then try to show the presentation in a location with slow or no Internet access, you would be in for big trouble. For a good review of OnLive check out this column by Walt Mossberg. Because they are free and easy to try, go ahead and try them out.
Monthly cell phone charges will get progressively more complex and more expensive and, of course, it's the monthly charges that really add up. That's the reason carriers often give away the phones; once you're hooked, you're hooked. The following chart compares plans from three major US carriers. This information changes rapidly so check current numbers before buying.
Phone bills consist of four components, calling plan (minutes), text messages, dataplan and other fees and taxes. The dataplan can be the most confusing so make sure you don't buy more than you use - you can monitor and check usage with the carriers app or website. Always use wi-fi when available. Don't make the mistake of listening to music or watching video on wi-fi and then wandering out of the wi-fi location. Your phone will most likely keep right on downloading those megabytes over the 3g or 4g connection.
This long promised glossary is not alphabetical since that doesn't work very well for this type of material. It is loosely organized in some logical groupings but it is short enough that the best approach is just to skim the words in the left column to find ones you've heard and wondered about. Often it seems like you are the only one in the room that doesn't know what the "cloud" is but you are not alone. Here's your chance to catch up and get ahead of most of the people you encounter.
Word
Definition
Mobile Devices
Smartphones and Tablets are the most
talked about mobile devices today. In a word, they are computers that are
portable in the extreme. They have processors, memory, operating systems,
keyboards and touchscreens for data entry and for displaying the output. Most
importantly, to qualify as general-purpose computers they allow user
installation of programs (apps in today’s vernacular). Without this last
requirement some current refrigerators – and future toasters – would likely
qualify as general-purpose computers.
Tablet
Tablets
are at the large end in terms of mobile screen size – typically seven to ten
inch diagonal measurement. The other primary difference from smartphones is
that tablets generally don’t have a connection to a cell phone network and if
they do it’s not used for phone calls – just for Internet activities. There
is nothing stopping a company from putting a cell phone capability into a
tablet. Two reasons they probably won’t: the tablet war is turning into a
price war and every penny they can cut from the cost is a penny they can
keep; the idea of talking into a tablet just seems strange and most tablet
owners have or will have a cell phone. Nomenclature will be confusing for a
while since someone could – and probably will – put telephone circuitry into
a ten inch tablet or remove it from a four inch smartphone.
Phone - Smartphone
Smartphones allow users to install apps of their choosing
Phone – Feature phone
Feature phones can perform tasks using the Internet such as email and web surfing.
They come with a fixed set of apps – calendar, contact list, etc.
Phone – Cell phone
Simple cell phones are used only for making
phone calls.
Cell phone contracts
Many phones receive
service from one of the carriers (AT&T, Verizon, etc.) based on a
contract. Monthly charges are based on four elements.
1)Number of
minutes of call time
2)Number of text
messages
3)Amount of
information sent and received (the dataplan)
4)Fees and taxes
Dataplans
are likely to cause significant confusion in the future since we are using
mobile devices more frequently and very few people know how many megabytes
are in a video.
Traditional cell phones do
not require dataplans. Prepaid cellphones are traditional cell phones that
allow you to buy minutes in advance. These are individuals with limited need
for a cell phone.
Internet TV
Much of our television in
the future will come through the Internet. A simple computer can be
incorporated into a TV set or offered as a standalone box. No matter the
form, these are real computers – generally with limited storage. Content is
streamed from the Internet not stored locally. They use the TV as a display
and a remote control or keyboard for input. Some have relatively simple
choices while others offer a full web browser on the TV.
App
An app is just a new name for a program. You used to install
programs; now you install apps.
Operating System - OS
All computers including
desktops, laptops, smartphones and tablets have a program called the operating system (OS). In the past
the three best-known computer operating systems were Windows, Mac and Linux.
Currently the top mobile operating systems are Google’s Android and Apple’s
iOS. There are at least ten mobile operating systems today but few are likely
to survive very long.
UI – User Interface
Ever since Apple
introduced the graphical user
interface in 1984 (icons manipulated with a mouse on a “desktop”) the User Interface (UI) has been
critical. Methods of interacting with a computer (using a mouse and keyboard)
have progressed slowly in recent years but touchscreen technology is changing the UI at lightening speed.
Wireless connections WiFi, Bluetooth, etc.
All of these are just the
various types of radio signals that are used to connect devices wirelessly.
They’re called radio signals since they were used for radios decades before
computers were invented. For a more detailed explanation check out my July blog post.
Cloud
In the simplest terms the Cloud means storing information
and running problems on the Internet rather than your PC. For the
professionals it is much more complicated and you can read more in my June
2011 Newsletter.
Internet and the World Wide Web (Web)
The Internet consists of millions of computers connected together.
They may be gigantic machines but even your personal computer is an Internet
computer when it is online.
The World Wide Web consists of software and files that allow anyone
to use Internet computers to store and retrieve information - information
that might be text, photos, music, etc.
A web server is one of the most important web programs since it
sends files (web pages) to you when you click on a link or type an address
into your browser. It sends (or serves) the page to you and then waits
patiently in case you want another file – possibly serving thousands of files
to other users in the meantime.
Sending and retrieving web
files is only one use of the Internet. Email is another. Email uses the
Internet but not necessarily the web. This situation is somewhat confusing
since many email services are now available through your web browser.
Protocol
If two computers (or two
people) are going to work well together, they have to agree on how they will
do things. Often these agreements are called protocols. Who sits where at a state dinner is
determined by the protocol for state dinners. In the case of computers, how
they exchange information is called a protocol that is described first on
paper – which signals are going on which wires, etc. To be able to
communicate both computers must have a program that implements a particular
protocol. Basically it’s a description of what characters will travel between
the two computers and in what order. You may hear about IP addresses – these
are the addresses used by all computers on the Internet (even yours)
according to the Internet Protocol.
Encryption
We all remember making up
secret codes at a very young age. Encryption
is just the name for a myriad of techniques that can transform a message –
text, photo, etc. – so it cannot be understood if it falls into the wrong
hands. Breaking enemy codes was a major undertaking in World War II and today
any spy agency worth its salt is doing the same thing with information
intercepted on the Internet.
Units – Bit, Byte and Megabyte
We’ve heard that all
information in a computer is stored as zeros and ones. If you put enough
zeros and ones together you can represent a text book or reproduction of the
Mona Lisa. If you take an image from your digital camera or off the Internet
and enlarge it many, many times, you will see individual picture elements,
(pixels or dots). Each pixel is a single color and that color is represented
by a number – a string of zeros and ones.
Storage space for a single
zero or one is called a bit – just
like storage space for a number from 0-9 is referred to as a digit.
A group of eight zeros and
ones is referred to as a byte. As
a rough approximation a single character of text can be represented by a
combination of zeros and ones stored in one byte (a=00000001, b=00000010,
etc.)
A kilobyte is roughly one thousand bytes; a megabyte is roughly one
million bytes and a gigabyte is
roughly one billion bytes. I say roughly because there are two definitions
for each of those terms but they are similar enough for most people to
ignore.
Pixel
A pixel is a single point (dot) in an image. A ten megapixel camera
can take pictures with approximately ten million pixels. Each pixel requires
several bytes of memory to record the color – see pixel depth.
Pixel depth
Each pixel (dot in an
image) can represent millions of different colors. The value stored for each
pixel indicates the color of that dot. The higher the pixel depth (more bits
to store the value), the more colors that a pixel can represent. For example,
if you stored the color of a pixel as a two digit number, you could store up
to 100 different colors – 00-99. Computers store values in binary but the
principal is the same.
Compression (JPEG or JPG for still pictures and
MPEG for videos) In practice there are many other compression standards.
Storing a color value for
every pixel in an image results in very large files. It is common practice to
compress the image by, for example, indicating that a large area of sky is
blue with only a few values – the numeric value for blue color and the
boundaries of the block of sky. A tiny speck of a bird in the sky might just
be tossed out in the process. The higher the compression, the smaller the
resulting file and the more image points will be lost or modified.
Videos can have each
individual frame compressed in this way but add interframe compression; if
two successive frames are nearly identical, only the changed pixels are
included for the second frame.
Broadband
Generally used to describe
high speed Internet access with a variety of speeds. Usually contrasted with
dialup connections.
Modem/Router
The telephone system was
originally intended to transmit human voices. When we began sending
information between computers over phone lines, there had to be a way of
changing zeros and ones to sound patterns (called modulating) when they were
sent and then back into zeros and ones (demodulating) at the other end. The
device we use is a modulator/demodulator (modem) - one at each end of the line.
If there are multiple
computers in your home or office and only one Internet connection, you need a
way to keep transmissions separated. Signals from a computer connected a
wireless network go first to the router which attaches a numeric code to
indicate which computer sent it. When a response to that transmission is
received over the Internet it comes back through the modem and then to the
router to send it to the correct computer. Today modems and routers are
usually combined into a single device that does both jobs.
HTML
A file type indicates what type of program created or can read a
particular file - .doc for MS Word, .xls for Excel, etc. Files that come over
the Internet to be displayed by a browser like Internet Explorer, Firefox or
Safari use .html or .htm as a file type.
Flash
Flash is
a type of file often used for video but for other purposes as well. Flash is
losing favor as other more modern programming tools are developed, e.g. HTML
v5.
PDF files
The pdf file type was developed in response to the many incompatible
file types that were causing confusion. The idea was that all computers could
have a pdf file “reader” so any document – word processing, spreadsheet, etc.
– that could be converted to a pdf format could be read on any computer.
URL
A Uniform Resource Locator is the fancy name for the Internet
addressing scheme. You could type an address into your web browser and call
it either an address or URL. URL is the cooler term.
Touchscreen
Smartphones and tablet
computers use display screens that can detect the touch of a finger or
special soft stylus. They can be programmed to respond to various gestures –
tap and double tap, as well as sliding motions involving several fingers.
Cheaper touchscreens require pressure but later, higher quality screens
respond to a very light touch. Touch gestures often imitate mouse clicks –
double click/double tap, click and drag/tap and drag, etc.
Domain Names
To provide some structure
to Internet addressing, the scheme starts with Top Level Domains. These
include .com, .edu, .mil, .gov and .biz - called generic TLDs. They are not
associated with any country. TLDs also include two letter country codes .us,
. ca. ru, etc. New top level domains are just being rolled out now.
Any organization that
wants an Internet address can apply for its own name – braley.com or
braley.us – consisting of a specific name associated with one of the TLDs.
Needless to say most common words and proper names are already taken.
This is how requests for
information are routed around the Internet. Braley.com is essentially a
folder of files stored somewhere on the Internet. One of those files is the home page that will be retrieved if
no further information is provided. In most cases, someone might want a
specific file and request braley.com/clients.htm. This is a file in the
braley.com folder
www, http, https, ftp
A web file usually starts
with www (world wide web) but if
you leave that out, your browser will generally insert it for you. The
Internet operates on Hypertext Transport Protocol - http -but again the browser will often add that to an address.
Secure web sites use https and it
is important to put that in to access those sites. FTP is the file transfer protocol – not a web service – which at
one time required a separate – non-browser – program. But like many other
services, FTP can usually be handled by your web browser.
Browser
A web browser was once a program with one purpose – to display
files ending in htm or html. These programs have been greatly expanded to
perform numerous other functions – see FTP above.
Email and web capitalization
Email addresses are NOT
case sensitive. Web addresses are NOT case sensitive up to the first slash
following the .com, .gov, .us, etc. Following that slash they may or may not
be case sensitive so you need to assume they are unless you know otherwise.
Braley.com is never case sensitive but the “file1.htm” in
Braley.com/file1.htm is likely case sensitive.
This seems like such an obvious question I'm amazed I've not seen it addressed more often. Android promoters gloat that their "platform" leads in sales but never explain why their tablets don't do the same. I have a theory. When most people buy a smartphone, they are thinking about its capabilities as a "phone". How many minutes do I get? Which carrier do I prefer? Is there a family plan? etc. The "smart"phone, i.e. computer aspect, is secondary. They may never address the operating system or the app stores since they are thinking in terms of replacing an old phone. Starting with that premise, anyone searching for a phone would more likely end up with Android - they are everywhere and many are less expensive than iPhones.
Buying a tablet is a different proposition. Consumers have no tablet experience so they have no natural starting point. This forces them down one of two paths. A few realize they are really buying a computer and investigate all the relevant technology and many are likely to go with Android. Most people though just buy what is available in most stores (iPad) or what their cool friends have (iPad). One of Apple's stealth moves with the first iPad was to place it in major retail outlets last year - Best Buy, Target, WalMart and Radio Shack - in addition to it's own 300+ stores worldwide. This leaves precious little prime shelf space for competing tablets.
If many smartphone purchasers aren't doing much critical thinking as I've suggested - after all they're just buying a phone - the companies may be forced to sell primarily based on price - as in the PC arena. While they may sell a lot of excellent Android handsets, they may not make sufficient profit to survive in spite of the sales figures. And speaking of sales figures, remember the difference between "shipped" and "sold". Sold is what matters; shipped means sent to retailers where they might languish for months before being sold - or returned to the maker.
If
there's one issue that haunts the Android "industry" it's the widely
discussed problem of fragmentation. Dozens of companies (Motorola, HTC,
etc.) make hundreds of Android models to be sold by numerous carriers,
in retail stores and online. There are differences in the phones -
different size screens, virtual or physical keyboards, price, etc.
Having choices is certainly appealing - with the iPhone it's black or
white, literally. However Android choices can be very confusing for
someone trying to find the "right" phone - like the potato chip aisle at
the quickstop - way too many choices.
Imagine if your one year old PC did not qualify
for the latest version of Windows.
This seems in some ways like the battle between Apple and Microsoft
for PC dominance but there is a significant difference. If
fragmentation in the PC world had been harmful, Apple would have been
the logical beneficiary because there were hundreds of PC manufacturers
over the years. But PCs were not all that different - they used the same
processors, the same disk drives, the same keyboards, etc. so
differences were either minor cosmetic factors or price. Most importantly they all ran the same operating system and most could be reliably upgraded for at least five years.
I previewed the iPhone 4S
last month the day after its introduction and I now have two weeks of
actual use under my belt. I used it in my office as well as to give a
presentation at an international conference. Yes, you can do a great
slide show by connecting your iPhone 4 or 4S to a projector. My draft of
last month's discussion actually referred to the iPhone 5. It's pretty
amazing that dozens of companies were involved in the development of the
device and millions were manufactured and the experts were still
guessing at the name until the formal announcement.
Predictions
concerning hardware where generally accurate - faster processor, much
improved camera, more memory, etc. I received mine October 14th - the
first available date - and I along with the overwhelming number of
reviewers were thrilled with the device. In particular the camera and
camera app are outstanding.
The more databases Siri connects to,
the less searches will be performed on Google..
The other half of the announcement was the new operating system - iOS 5.
This free evolutionary OS upgrade claims over 200 new features and runs
on all recent iPods, iPhones and iPads (see Fragmentation below). To
top it off the biggest announcement of the day was not the phone -
I've been excited about photo editing with a touch screen ever since I got my iPhone. The iPad and its numerous apps makes creating great images a snap. This does not replace "sturdy" desktop applications for sophisticated photo manipulation - at least for now. In particular ten inch screens will always be a limiting factor.
Having said that I wanted to show an example of what I did in a matter of minutes starting with a 3MP image taken with my iPhone while strolling along the Mississippi in Minneapolis. I sent the image to my iPad using PhotoSync and used four of the 187 filters in PhotoStudio to create the special effects.
At two recent lectures on Mobile Technology I surveyed participants on their use of social media. It was a simple eight question survey not directly related to the topic I was covering. Several points concerning the participants:
They covered a wide age range with many in the 30-50 year range.
They were above average in tech knowledge based on their professions.
Some were small business owners and others worked for companies of all sizes in the computer training field.
Three of the four questions ask about their use of Facebook and Twitter. The last question ask whether they owned a smartphone or tablet computer.
General results:
Nearly 80% had smartphones but only 17% had a tablet.
While two-thirds used Facebook weekly only one-quarter used Twitter that often.
Business application - use of Facebook and Twitter:
Facebook was used to communicate with clients by 40% of participants but only 20% used Twitter for that purpose.
In a similar vein 33% used Facebook to receive information from companies while 24% used Twitter to do that.
With a total of eight possible responses, a rough measure of "tech savvy" would be the number of boxes each person checked - have a smartphone, use Facebook weekly, etc. etc. Using that measure no one scored the maximum of eight while 26% checked three - typically Facebook weekly, have a smartphone and one additional item. 19% checked four or more but 7% did not check any of the eight boxes.
This was a small sample but I think the results are informative. First and foremost, even though everyone is told they have to use social medial to communicate with stakeholders, a significant majority don't do that at the present. As you might expect the few "heavy hitters" dominated the results and 38% had no business contact at all with others using social media. This is after several years of hearing how Facebook is taking over the world and "everyone" is doing it.
Like most surveys of this type, I made no attempt to assess how well these techniques worked - are people just tweeting and hoping it works or can they measure actual success in product sales or revenue results.
There are many other social media platforms I did not include - primarily to keep it simple. I assumed that a significant number where on LinkedIn but evaluating actual usage would have been somewhat more difficult. Several other lesser known services were considered and will be included in future studies.
How often do you hear someone talk about "what people want?" Whether it's politics or technology, pundits act as if all people want the same thing and they know what it is. This leads to ridiculous criticisms of things like the current smartphones and tablets; notice I'm avoiding the political part!
You hear, for example, "the iPad and other tablets are flawed because people don't like virtual keyboards - they want a real keyboard. The reporter goes on to say "when I write my stories, I blah, blah, blah." This storyline makes it sound like a) they know what everyone wants and b) they represent everyone by talking about their personal needs in the same sentence.
I'm pretty sure "people" don't all want the same thing - whether it's in their computers or condiments on their hot dogs. This is more than just a complaint about the state of journalism - it goes to the core of how computers have been developed over the years.
Real keyboard - you want a real keyboard!
Let's look at automobiles as a starting point. There are several dozen different basic auto designs because "people" don't all want the same thing. There are compact hybrids and nine passenger SUVs and a whole crop of "crossovers". Because PC functionality has been controlled by one company for nearly thirty years, only one version of one product was necessary - the Windows PC. I don't know what "all people" want but I do know that
The Perfect Tablet will include
six card readers, firewire and
USB connectors, a mouse,
a keyboard, SLR equivalent cameras
as well as serial and parallel ports
"some people" would have preferred something different - specifically a whole lot easier to use and less prone to malware. Almost no one claims to use more than ten percent of the functions of Word or Excel - hyperbolic cotangent anyone? The fact that people do not always want the same thing requires that companies build more than one thing - at least if there are any competitors to worry about. Microsoft's only real competitor was Apple and they were not much better. Their product - although easier to use and less prone to malware - was still only one version. It ran MS Office just like Windows. Notice that both companies dropped the easy to use and cheap or free versions of their office software - MS Works and Apple Works. They did have decent alternatives to the gargantuan MS Office but no more.
As we turn the corner toward mobile devices, my hope is that companies will not try to build the "perfect tablet" that meets the needs of everyone. If they do, it will include six card readers, firewire and USB connectors, a mouse, a keyboard with numeric keypad, SLR equivalent cameras (front and back), dual game controllers, as well as serial and parallel ports - hey some people still have that 1995 dot matrix printer to hook up. And of course it must run Excel, Word and PowerPoint using any remote device purchased since 1950.
In the case of tablets the smarter decision will be to either offer several models - one with and one without a keyboard - or one product that has options - such as docks we've used for years or the wireless keyboard approach on the iPad. The primary driving force for tablets is size, weight, convenience and ease of use. I'll be terribly disappointed if they evolve into dinosaurs as PCs have done. Adding layer upon layer of functionality was no problem with desktop computers - users could just buy bigger monitors so there was some place to see the actual words in their document. Ten inch screens, limited keyboards and slower processors that characterize tablets may finally reverse the trend away from mega-applications.
The new crop of ultrabooks notable for their lack of hard drive and optical drive but with the ability to run full versions of Windows or Mac OS represent another change in direction. They are distinguished not by new features but by features that are omitted - what a refreshing change. Now only if the next version of MS Office included a version of Word with five hundred commands rather than one thousand five hundred. The Apple iWork package may indicate the new direction for productivity software.
There are so many products, technologies and companies involved in the rapidly evolving tech market today, I thought it would be helpful to summarize some important facts in a simple table. I made a list of twenty-four products including computers and a variety of mobile devices and software - then added several service related factors such as shelf space and the cloud.
I created a table with eight leading vendors across the top to see how these vendors competed in the twenty-four areas. I think it's going to be difficult for companies to survive with only a handful of products - desktop PCs and laptops for example. You can click on the image below to enlarge the chart. Let me know what you think.
