Research for eBook: Handheld computing

What are handheld devices:
- Handheld devices are portable computers that are small enough to be held in somebody’s hand and are very convenient to use and carry . typically having a display screen with touch input and/or a miniature keyboard that can be slided out 
- They are  typically used for PIM (personal information manager) purposes such as maintaining schedules, keeping names and phone numbers, doing simple calculations, taking notes, and, with an internet connection, exchanging e-mail and getting information from the Web.

Types: 
- PDAs 
- netbooks 
smartphones 


- media players


How do handheld devices work:
- powered by microprocessors

Phone Advice

      My daughter insists that her phone be Wifi capable? What does this mean? Why does she need it?”
W    Wifi connectivity is a form of web browsing using mobile devices when connected to an Internet connection which basically means that she can use the Internet from her mobile phone when she connects to your hose Internet connection. This is extremely convenient to have phone that supports wifi as it is a quick and easy way to use Internet at your finger tips.
      “She wants the camera in the phone to be at least 5 Meg thingys, what does this mean? Does she need it?”
      You mean megabytes 5 megabytes which means she can take photographs on her phone which will be of reasonably good quality as 5 mb is a very good camera quality for mobile devices.  
     
     “My daughter wants a phone with a capacitive touch screen. They seem more expensive, what advantages do they offer over other types of touch screens?”
      In the cell phone industry there are two major categories of touchscreen displays: capacitive touchscreens and resistive touchscreens. Capacitive touchscreen displays rely on the electrical properties of the human body to detect when and where on a display the user touching. Because of this, capacitive displays can be controlled with very light touches of a finger. The advantage is that they do on not require a stylus.
       
             "Are all phones as smart as one another what is the smartest phone at the moment and why?"
                No not all phones are as smart as one another. The smartest phone at the moent would be the iphone 4 this is because of its advanced feature, its usability and functionality.
        “She wants to take lots of video and photos. How do I know which phone can store the most videos and photos?”
       Most phones usually have a removable micro or mini SD card and usually comes with 2 GB memory but you can always purchase extra memory at an affordable price. But when buying phones like the iphone you cannot buy extra memory.
       “She says she wants to be able to buys apps. What are apps? What sort of useful apps cold she access? What types of phones can buy and use apps?”
      Apps is an abbreviation for application. An app is a piece of software. It can run on the Internet, on your computer, or on your phone or other electronic device. There are many productive applications such as Evernote which is an excellent organisation tool there are also may other organisational and educational apps as well as fun apps avaliable some are free and others cost money. Well you can buy an andrioid phone which has a brilliant app market and these phones are affordable as well, then there is the OVI app store this one is moderatley good and than theere is the apple app store. So there are many phones that allow you to use applications.

How much is:

1000MB = 1 GB
500 GB = approximately 500 000 megabytes
500 KB = approximately 0.5 megabytes

how many bytes in:

a kilo this has 1000 bytes
a mega has a 1 million 
a giga has a billion 
and a terra has a 1 trillion 

What is a Byte

A byte is a group of binary digits or bits (usually eight) operated on as a unit.

Binary numbers

computers use binary numbers, and therefore use binary digits in place of decimal digits as they don'y use base 10 Therefore, a binary number is composed of only 0s and 1s

The word "bit"

The word 'bit' was derived from the term binary digit (0 and 1)

"normal" counting numbers

Digit

A digit is a single place that can hold numerical values between 0 and 9. Digits are normally 
combined together in groups to create larger numbers. For example, 6,357 has four digits. It is understood that in the number 6,357, the 7 is filling the "1s place," while the 5 is filling the 10s 
place, the 3 is filling the 100s place and the 6 is filling the 1,000s place.

Mid pictures







UMPC images








UMPC / MID device for school

specific UMPC device

I would choose the Smasung Q1 because
- it is convenient as it is 7 inches 
- touch screen 
- it looks attractive 
- has stylus to navigate on on screen. 
- has 512 megs of DDR2 RAM despite its small size
- has wi-fi
- has Bluetooth 

- consists of 900MHz Celeron processor.  

My choice

I would select a notebook as it would be larger in size, yet it is portable, it supports flash, it would allow me to use any web browser of my choice e.g. chrome, firefox etc. Also it supports my need which are web browsing this is done extremely easily through the moderately simple through the interface, supports flash. It is also easier for me to use in order to get things that require a lot of typing like assignments etc. through the large keyboard.

iPad vs. Netbook

- ipad is lighter making it more convenient
- ipad does not support flash whereas the netbook does
- the ipad has more user friendly interface e.g pinch in zoom
- net book is more functional as to getting work done, has a better keyboard

MID and UMPC

What are MID and UMPC devices? How do they differ. List atleast three examples of both types of devices & include images.
UMPC:
- Business-class device for enterprise users
- Runs a "heavy" OS like Vista
- Optimized for office-use applications like Excel, Word, etc.


MID:
Consumer-class lifestyle device
- Runs a 'lightweight" OS with quick startup like Linux
- Optimized for things like media playback and web surfing
- In 2009 (or so) Moorestown-based devices will be classed as MIDs only


Examples of UMPC devices:
  1. Samsung Q1 
  2. ASUS R2H 
  3. Tablet Kiosk Eo 
  4. Amtek 700 
  5. Founder Mininote 
  6. Paceblade Easybook/Smart Caddie 
  7. Avertec AHI 
  8. Fujitsu P1510D 
  9. DualCor cCP
  10. ECS EZ30D
Examples of Mid Devices:
- Nokia N810
- Lenovo idead pad U8 
- Samsung Galaxy tab

Notebook vs. Netbook

Notebooks and Netbooks use the same basic form factor -- the main differentiator is size. That form factor is a computer with two main parts: a screen and a ­keyboard attached by hinges. In general, netbook computers are smaller and lighter than notebook computers, which in turn are smaller and lighter than laptops. But there are no specific size or weight classes for computers.


Netbooks are devices designed purposely for the Internet, to communicate, learn, and view information. They have in common a compact form factor of seven to ten inches, are light-weight, feature comparatively longer battery life than notebooks, and are less dependent on a battery charger during the day. They are easily portable and can be easily moved from one place to another place. They may contain more than one wireless method to connect to the Internet

Dual Core Processor

In a dual core processor each core handles incoming data strings simultaneously to improve efficiency. Just as two heads are better than one, so are two hands. Now when one is executing the other can be accessing the system bus or executing its own code. Adding to this favorable scenario, both AMD and Intel's dual-core flagships are 64-bit.


To utilize a dual core processor, the operating system must be able to recognize multi-threading and the software must have simultaneous multi-threading technology (SMT) written into its code. SMT enables parallel multi-threading wherein the cores are served multi-threaded instructions in parallel. Without SMT the software will only recognize one core. Adobe® Photoshop® is an example of SMT-aware software. SMT is also used with multi-processor systems common to servers.


A dual core processor is different from a multi-processor system. In the latter there are two separate CPUs with their own resources. In the former, resources are shared and the cores reside on the same chip. A multi-processor system is faster than a system with a dual core processor, while a dual core system is faster than a single-core system, all else being equal.
