Today we looked at our Term 3 assignment.
I am working on my own as it's going to be easier to complete it rather than working in pairs or three.
I have regestered myself on student net and ahve read through the assignment, i am well aware of what the assignment is asking me to do. I am deciding on what topics I should do.
The bells gone i have to go
bye :)

Handheld Computing
1.What are MID and UMPC devices? How do they differ. List atleast three examples of both types of devices & include images.
MID (Mobile Internet Device) are a consumer-class lifestyle device which runs a "lightweight" OS quick startup like Linux. They are optimized for things like media playback and web surfing. In 2009 (or so) Moorestown-based devices will be classed as MIDs only. Whereas the UMPC (Ultra Mobile Portable Computer) are business-class device fr enterprise users, they run a "heavy" OS like Vista and are otimized for office-use applications.
Some examplse of MID and UMPC devices are:
MID - Laptop
- iPhone
- Nokia N810
UMPC - Ipad
- Acer Aspire One (A110L)
- Viliv X70 EX
2. What are the differences between a Notebook handheld computing device and a Netbook handheld computing device?
- There's more power, Memory and storage in the Notebook rather than the Netbook.
- Notebook can run Windows Vista, XP, it had a dual core processor, it's got a large, regular hard drive that spins and it can have anywhere from 80 to 320 GB of storage onboard. However, the netbook have a very small 4 ir 8 GB solid state drive. Sometimes they have bigger 32 ir 64 GB solid state drive. And then occasionally they'll come with a 80 GB hard disk drive, But again from 4 to maybe 80 (in netbook) to 80 to 320 (in a notebook) is a huge difference in storage. In a netbook you won't be able to store a lot of movies, or a lot of videos it's pretty much going to be a few pictures, a few songs, becuase you can play music on it, but that's about it. You're not going to be able to load a bunch of games or applications, there's not going to be Photoshop or Word or Excel.
- The whole point of the Netbook is for Net-Centric Computing is surfing the web, checking your mail, running web applications, only simple stuff like that due to the processor.
- The processors in a Netbook and Notebook are different.
- The Notebook can do anything, it has a big hard drive, DVD drive, lots of inputs and outputs, full operating system, whereas the Netbook is only for using the internet and/or Netcentric computing
3. Describe the design & features of the Apple iPad then discuss how it compares with a Netbook.

Bits & Bytes & Memory
In its very essence computers are a combination of numbers and digits.
8 bits = 00000000 or 11111111 or 00001111 and so on.. = 1 Byte
1000 Bytes - 1 Kilo byte
1000 Kilo bytes = 1 Megabyte
1000 Megabytes = 1 Gigabytes
1000 Gigabytes = 1 Terrabytes
Everything on the computer is made up of 0s and 1s.
There is an ASCii code
Eg.
The ASCii code for 'a' is 01100001
The ASCii code for 'b' is 01100010
8 bits = 00000000 or 11111111 or 00001111 and so on.. = 1 Byte
1000 Bytes - 1 Kilo byte
1000 Kilo bytes = 1 Megabyte
1000 Megabytes = 1 Gigabytes

CPU (Central Processing Unit) quiz
1) What is the function of the CPU?
The CPU helps a computer to do its work as it is the heart of any normal computer. The CPU is a complete computation enginge that is fabricated on a single chip.
2) What was the name of the first CPU?
Intel 4004, introduced in 1971
3) Referring to the graph on page 2 of the article, describe how the speed of CPU's have changed.
The speed of the CPU's have changed as there have been more MIPS added to each new computer throughout the years 1974 to 2004. There also hyas been many touches on the transitions, microns, clock speed and data width.
4) What does MIPS mean?
MIPS stands for "Millions of Instructions Per Second" and is a roguh measure of the performance of a CPU.
Modern CPUs can do many different things that MIPS ratings lose alot of their meaning, but you can get a general sense of the relative power of the CPUs from this column.
5) Research (Google it) what is a dual core processor, what is multitasking and how do the two work together?
