Mobile Computing n The ability to use technology “untethered” ¨ Not continuously connected to the base or central network n Requires that mobile computing activity be connected wirelessly to and through the internet or to and through a private network ¨ Ties the mobile device to information through the use of battery powered, portable, and wireless devices

History of Mobile Devices Radio transmitters and wireless communications systems were base stations, operated at fixed locations, with large antenna towers n 1950’s 12 volt automotive electrical systems gave rise to 12 volt devices such as two-way radios and mobile rigs n

History of Mobile Devices (Cont. ) n Companies such as Motorola sprung up to support the need for mobile devices - Such as taxicab radios, police radios, and trunk mount systems n Today there is a wide variety of mobile computing platforms

Mobile and Portable n Mobile n ¨ Wearable - Vehicular n Today there is a fuzzy boundary between the two ¨ Many small handheld phones and computers will operate on 12 volts Portable or handheld n There is a proposal to have these two connect by wireless ad-hoc networks

Wireless Technology n Day to Day transfer of information is increasing rapidly and new developments are continually expanding ¨ Even so, majority of technology doesn’t provide as much bandwidth or accessibility as landlines ¨ Transmission range for wireless is usually related to the data transmission speed n The further the wireless signal has to travel the less data it can carry per second

Wireless Technology (Cont. ) n Most advanced developments of wireless broadband deliver downstream data n Satellite communications ¨ Good transmission rates, but the cost is too high, typically $1, 000 or more

Security Physical devices along with the data has to be protected n Difficult problem n ¨ Poorly designed communications protocols ¨ Raises the issue of how much information employees are allowed to carry and what procedures to follow so information doesn’t get stolen

Mobile Users n Mobileer ¨ One who uses mobile communications devices n Three types: Telecommuters who work away from office but stay directly connected to it from a remote location 2. Casual telecommuters and other workers who work a few days per month outside the office 3. Predominantly mobile employees 1.

A Few Mobile Devices Laptop computers n PDAs and handheld PCs n Calculators n Pagers n Smart phones and cell phones n Task devices n ¨ Bar code scanners

Laptop Computers n A brief history ¨ The n n n first laptop? … maybe 1979 by William Moggridge Used by NASA on space shuttles in the 80’s 340 K byte bubble memory Die cast magnesium case Folding electroluminescent graphics display screen 1/5 the weight of any model equivalent in performance

Gavilan Computing n First promoted laptop ¨ Manny Fernandez was the founder of Gavilan Computers ¨ In 1983, it was considered the first fully functional laptop computer ¨ Good for executives

The Osborne 1 n First true portable computer ¨ Created by Adam Osborne in 1981 ¨ It weighed 24 lbs and cost $1795 ¨ 5 inch screen ¨ Modem port ¨ Two 5 ¼ floppy drives ¨ Large collection of software ¨ Battery pack

More Laptop Firsts n 1981 - Epson HX-20 ¨ Battery powered ¨ 20 character by 4 line LCD display ¨ Built in printer n 1983 - TRS-80 Model 100 ¨ Created by Bill Gates & Kazuhiko Nishi ¨ 4 lb battery operated portable computer ¨ Flat, more of a lap top design

Even More of Laptop Firsts n 1989 - Macintosh Portable ¨ Produced by Apple ¨ Later evolved into Powerbook

How Laptops Work n The Microprocessor ¨ Internal instructions stored in memory ¨ Access its own memory ¨ Receive instructions from you n n Keyboard Mouse Touchpad Trackball ¨ Display n n data to you Cathode ray monitors LCD displays

How Laptops Work (cont) ¨ Receive data through storage devices Hard drive n Zip drive n CD/DVD drive n ¨ Sends data to: Printers n Modems n Networks n ¨ Powered by AC or batteries

Disk Drives n Internal hard disk drive ¨ 6 to 20 GB ¨ Stores: Operating systems n Application programs n Data files n ¨ Laptops have less space than desktops

What Laptops Can Do n There are many fields of use for laptops ¨ Education ¨ Presentations ¨ Note taking ¨ Laboratories ¨ Entertainment (CD, DVD, mp 3) ¨ Law Enforcement ¨ Astronomy (CCD) ¨ Navigation (GPS) ¨ Business

PDA’s n Personal Digital Assistant ¨ Serves as an electronic organizer/day planner ¨ Capable of sharing information with you computer ¨ An extension of a PC… not a replacement ¨ Manage personal info ¨ Can connect to: n n Internet GPS ¨ Can run multimedia software

Uses of PDA’s n Manage Personal Information n n store contact information (names, addresses, phone numbers, e-mail addresses) make task or to-do lists n n n n take notes write memos keep track of appointments (date book, calendar) remind you of appointments (clock, alarm functions) plan projects do calculations keep track of expenses

More Uses For Select Models ¨ Send or receive e-mail ¨ Do word processing ¨ Play MP 3 music files ¨ Play MPEG movie files ¨ Get information (news, entertainment, stock quotes) from the Internet ¨ Play video games ¨ Integrate things such as digital cameras and GPS receivers

The First true PDA? n 1978 - LC-836 MN ¨ Made by Toshiba ¨ Robert Hotto & Judah Klausner ¨ Main purposes Store memos n Store phone numbers n n 836 led the way for the future

How Do PDA’s Work n Parts of a PDA ¨ microprocessor ¨ operating system - tells microprocessor what to do ¨ solid-state memory – ROM chip ¨ batteries – life depends on types of usage ¨ LCD display n 65, 536 colors, 160 x 160, 240 x 320 ¨ input device n Mini keyboard, touch screen, stylus ¨ input/output ports n data synchronization

History of Calculators

Origin n First calculator was invented by the Chinese called the Abacus Was first built within the year 3000 BC Was widely used by merchants and clerks.

History n Wilhelm Schickard ¨ First to build automatic calculator ¨ Was built in 1623 ¨ Called it the Calculating Clock

History n n n French Philosopher Blaise Pascal Created the Pascaline in 1642 Uses ¨ Thought his machine could save labor and time. ¨ Also used for taxes

History n n n Charles Babbage “Father of Computing” Had the first successful automatic calculator and is known for his precision in engineering

Time Goes By. . . Scheutz Calculator- 1853 Brunsviga Type A- 1892 Baldwin Calculator -1873 American Arithmometer- 1898

Finally the 1900’s n IBM 1954 ¨ Comes out with all transistor calculator. ¨ 1957 release first commercial all transistor calculator n n IBM 608 1961 Bell introduces the Punch/Sumlock Comptometer - ANITA

Technology Gets Better! n Not only was technology better but cost more too! ¨ These machines usually ran $2200 - $2500 ¨ This included a thirteen digit capacity ¨ Average desktop weight was 55 lb-100 lbs ¨ Could Add, Subtract, Multiply, Divide, and sometimes do square roots.

First hand held calculator n Introduced in January 1971 ¨ The Sharp EL-8 Weighed one pound n Used a vacuum fluorescent display n Rechargeable batteries n Sold for $395 n

Scientific Calculators n First pocket ¨ Hewlett Packard with the HP-35 ¨ Used RPN (Reverse Polish Notation) or Postfix Notation. n Texas Instruments also introduced the SR 10

Upgrades n The scientific calculators were introduced to Continuous memory. n Data was retained after calculator was shut off. First calculator capable of symbolic computations was the Hp-28 n First graphing calculator was the Casio fx 700 G n

Present Day Calculators n n In 2002, HP announces they will no longer make calculators anymore Texas Instruments will capitalize on their sleek design of the new graphing calculators

The Basic Calculator n Basic Calculators include ¨ Battery or solar powered ¨ Display- LED lights or Liquid crystal with 8 -10 digit display ¨ Electronic circuits Keyboard display n ¨ n n n ¨ Ten digits Equal sign Four arithmetic functions Cancel or clear button On and off Square root and percents Can be found in n n Cell phones Pagers Wrist watches Local stores

Sophisticated Calculators n n Include same functions as basic Support ¨ Trigonometry ¨ Statistics ¨ Graphs ¨ Algebra ¨ Equation solvers ¨ Financial models ¨ Scientific notation ¨ And holds Games

Leading companies Sharp n Casio n Hewlett Packard n Texas Instruments n
