Today we were informed about our next assignment which is on multimedia. We were able to choose from groups of 1-3. My group consists of; Steph, Crishna and myself. Since our group has 3 members we would have to complete 12 topics, 4 each. The topics we have chosen are:
Me; Netbooks, Pircay and Copyright, Motherboards and Wifi
Crishna; Digital Television, Software License types, CPUs and Wireless Broadband
Steph; Handheld Multimedia Devices, Secondary Storage, Bluetooth and Social Networking.
This lesson we also had a preview of the possible sites/programs we may use to produce our assignment. It was a unanimous desicision that the we will be creating our program with wix.com.

Refer to these sites; 'site 1' and 'site 2'
1. What are MID and UMPC devices? How do they differ. List atleast three examples of both types of devices & include images.
UMPC; Ultra Mobile Portable Computer
•Business-class device for enterprise users
•Runs a "heavy" OS like Vista
•Optimized for office-use applications like Excel, Word, etc.
e.g. -Viliv N5, Netbook Navigator Nav 9, Archos 9
Refer to this 'video'
2. What are the differences between a Notebook handheld computing device and a Netbook handheld computing device?
Refer to these sites; 'site 1' and 'site 2'
3. Describe the design and features of the Apple Ipad then discuss how it compares with a netbook.
4. Of the 3 handheld devices - Notebook, netbook & Ipad - which one would suit your needs and why?
I believe the Notebook would suit my needs as a student as the Netbook's screen would be too small which gets annoying and the Ipad doesn't have a USB port which would be a problem as all my work is saved on my USBs.
5. If I was looking for a UMPC device with a screen size of 10 in or less, which would you reccomend? Justify your choice.
Refer to the videos at this 'link'
6. How would you envisage students 5 years from now using one of these devices at school. Select any UMPC/ MID device that you have researched that would meet a students needs, justify your choice.

bits and bytes questions.
1. What is a Digit?
A digit is a single number
2. “normal” counting numbers used in everyday life a based on what sequence of numbers?
0 1 2 3 4 5 6 7 8 or 9
3. Where does the word bit originate from?
bit is short for binary digits
4. Binary numbers don’t use base 10. What base do they use? What digits are available in base 2?
Binary numbers use base 2 which is a combination of 0 and 1s.
BASE 10
If 6,357 can be written as;
(6 * 1000) + (3 * 100) + (5 * 10) + (7 * 1) = 6000 + 300 + 50 + 7
How would you write 4,321?
(4 * 1000) + (3 * 100) + (2 * 10) + (1 * 1) = 4000 + 300 + 20 + 1
7. What is a byte?
A byte is 8 bits
8. How many bytes in a kilo, mega, giga and tera bytes?
kilo: 1000 bytes
mega: 1000 x 1000 bytes (1000 kilobytes)
giga: 1000 x 1000 x 1000 bytes (1000 megabytes)
tera: 1000 x 1000 x 1000 x 1000 bytes (1000 giga bytes)
9. Complete the following conversions;
1000 Mb = 1 Gb
500 Gb = 1000 x 500 Mb
5000 Kb = 5 Mb

memory.
bit = 0 or 1 (one digit)
8 bits --> e.g. 00000000 --> 1 byte
....................10101010
1000 bytes = 1 kilobyte
1000 kbyte = 1megabyte
1000 mbyte = 1 gigabyte
1000 gbyte = 1 terabyte
e.g. ASCi code
"a" --> 01100001
"b" --> 01100010

cpu questions.
Read the article (here) to find the answers to the following questions.
1. What is the function of the CPU?
CPU stands for Central Processing Unit. It is a complete computation engine that is fabricated on a single chip.
2. What was the name of the first CPU?
The first microprocessor was the Intel 4004, introduced in 1971
3. Referring to the table on page 2 of the article, describe how the speed of CPU’s has changed.
Through the years, the speed of CPU's have increased as technology has become more advanced.
4. What does MIPS measure?
MIPS stands for "millions of instructions per second" and is a rough measure of the performance of a CPU.
Most modern PC’s use what are called dual core processors. It is often stated that such processors improve multitasking.
5. Research (Google it) what is a dual core processor, what is multitasking and how do the two work together.
The most recent trend in computing is the use of mobile devices – effectively portable computers, whether they be your smart phone, your i-Touch of some Mobile internet Device (MID).
6. Read the article (here) about the Intel Atom processor then post about what benefits this processor offers mobile devices.
