Last lesson I started working on my eBook. The topics i will be researching and putting in my eBook are:- Handheld Devices
- Piracy and Copyright
- Secondary Storage (Hard Disk Drive & DVD and Blu-ray Disks)
- Bluetooth
Last lesson i found information on handheled devices - These are my findings:
What are handheld devices? A handheld device/mobile device/handheld computer is a pocket-sized computing device, typically having a display screen with touch input and/or miniature keyboard.
What do we use them for? Who uses them? People who require internet/computer use on the go mostly use these devices.
This lesson I am continuing to gather information to place in my eBook

Bits and Bytes.

1. What is a Digit?
A digit is a single place that can hold numerical values between 0 and 9.

2. Normal counting numbers used in everyday life are based on what sequence of numbers?
They are based on the decimal sequence of numbers.

3. Where does the word bit originate from? Binary digit was combined to create it.

4. Binary numbers don’t use base 10. What base do they use? What digits are available in base 2?Binary numbers use a base-2 number system. The digits available are 0-1.

5. What is a byte?
The byte is a unit of digital information in computing and telecommunications and usually consists of eight bits. A byte is made up of bits.

6. How many bytes in a kilo, mega, giga and tera bytes:
kilo: 1024 bytes
mega: 1, 048, 576 bytes
giga: 1, 073, 741, 824 bytes
tera: 1, 099, 511, 627, 776 bytes

7. Complete the following conversions:
1000 Mb = 0.9765625 Gb
500 Gb = 512 000 Mb
5000 Kb = 4.8828125 Mb

Handheld Computing.

1. What are MID and UMPC devices?

UMPC (Ultra mobile personal computer)
- Business-class device for enterprise users
- Runs a "heavy" OS like Vista
- Optimized for office-use applications like Excel, Word, etc.

MID (Mobile Internet Device)- 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

2. What are the differences between a Notebook handheld computing device and a Netbook handheld computing device?

Notebook:

 - Larger than a Netbook

- Can run more complicated programs like Photoshop etc.

- Runs out of power quicker

- Has a dual core processor

- Stores more memory

 Netbook:

- Mainly for checking your emails, twitter etc

- Small, handy for carrying around.

- Doesn't store much memory.

- Runs basic programs like Word etc.

3. Describe the design and feeatures of the Apple iPad then discuss how it compares with a Netbook:

- 2 cameras

- Thinner and therefore lighter

- long battery life

- LED, backlit display

- Multi touch

- Wifi and 3G

The iPad is alot thinner and easier to use and can do a wide variety of things on it. Like take photos, download apps, listen to music easily and browse the web easily. it is also touch screen which many people prefer. The size of the ipad also makes it alot easier to take places.

4. Of the three handheld devices which one would suit your needs and why?

I think the ipad would suit my needs the best because it is capable of doing alot of things and i have always liked Apple and i trust them. The iPad is also good for when i go away, i can take it with me.

5. If i was looking for a UMPC device with a screen size of 10 inch or less, which would you recommend?

I would recommend the iPad because it is the size suited and is capable of fulfilling all your needs.
