Today i designed and created my first "scratch" miniclip. It included three Sprites. A Mouse, Hawk and Sun. Its a cute little clip about a hawk eating a mouse. The main Sprite that moves is The Hawk. The sun and Mouse talk and show their thoughts. I did a simple clip to get the hang of Scratch before i started something more complex and substantial.

ITS ALL DONE!!
YAY! WE finally completed our WIKI SPACE FOR MEMORY! I'm very excited and happy. Iv'e been waiting for this moment! Now you all can go and check out the fanastic page and drown yourself into the wonders of computer memory!
Here's the link:

Somebody call 000!
For some reason when i wanted to look at all my blog posts, i could only see the 7 most recent ones and not the ones before them. So i decided to check out what was happening. I decided that something had to be wrong with the layout because just the other day i could see all of them. I began by editing my layout and then it came to my attention that the main page could only hold 7 posts. So to look at the others i would have to go on another link. Thus i fixed that up and it was all back to normal. Phewww...
Touch' Ups.
We had all completed our parts in the assesment. So i looked over our page and realised that it needed to be a bit more eye-catching and exuberant. So i decided to add some of the pictures i researched a couple of lessons ago. I made it interesting and funny to read. My group members also liked it.
Adding the Info
Well after researching a lot and narrowing all the information down. I finally wrote a very detailed but still interesting brief paragraph or two about the ROM. For example how much it costs, what does it do etc. It took a lot of time and effort but i managed to do a very good job. I saved my work and made it as interesting as i could. I also put it under small sub-headings so it would be easier for the viewers to read and understand.
ROM da BOMB!
Due to, Jess and Stef doing Ram and Moores Law. I decided to do ROM. So i researched a couple of websites that had good amount of info and that would expand my knowledge on Memory excessively. I learn't things like:
-It stands for "read only memory"
-ROM refers to Masked ROM which is the oldest type of solid state ROM. Its fabricated with the desired data permanently stored in it, therefore it can never be modified.
Here are some of my links to the sites i went on:
http://en.wikipedia.org/wiki/Read-only_memory
http://computer.howstuffworks.com/rom.htm
http://wiki.answers.com/Q/What_is_ROM_in_a_computer
These websites agve me a lot of useful information and interesting facts.

Pick Pics!
I have been looking through the internet in search for some good images to jazz up our Memory page in wiki spaces. It was kind of difficult to find some interesting and fun ones, but i managed to get a few. I found many pictures of Ram's and Rom's but they all looked the same, unless i was looking at the wrong *RAM*. Hahahaha.
I retrieved some funny comic/cartoon images and some normal factual ones too.

MOOres Law
Jessica, my other group member researched and wrote about the Moores Law. I read over her work and actually found it really interesting.
Seriously... who would have known that almost every measure of the capabilities of digital electronic devices is linked to Moore's Law. For example the, processing speed, memory capacity, even the resolution of LCD screens and digital cameras!
Here is the Link to our Memory page so far. It includes information on basic computer Memory,Moores Law and RAM.

Jamming with RAM
No, i don't mean the homeloan RAM. I mean the computer RAM! One of my group members Stephanie, wrote about one of the main features of computer memory! This was RAM. I watched her research it and write it. We looked at the main features of it, like what it does, what it is and how much it costs. She and i learnt a lot that day.
For Example:
- it stands for (Randomn access Memory)
- it refers to the fact that any piece of data can be returned in a constant time.
ETC.

Memory Basics
Memory is one of the most important parts of a computer. What would happen without it? Frankly, the thought of this happening sends shivers down my spine.
Some basic info that i found put today is that:
-memory refers to computer components, devices and recording media that hold digital data for some period of time.
- provides one of the core functions of the modern computer, that is information maintenance.
-it is used most often to identify fast, temporary forms of storage.
-every time something is loaded or opened, it is placed into RAM. This simply means that it has been put in the computer's temporary storage area so that the CPU can access that information more easily.

Site Sights!
When we received this assignment, my group got the topic MEMORY. In my group we have, Stephanie, Jessica and myself. On the first lesson we read through the assignment sheet and looked at all the things we needed to put in our wiki. Then we briefly skimmed through some useful websites on the net. We got a few ideas about what we were suppossed to do. Here are some of the Links of the websites we looked at:

M--E--M--O--R--Y What does it spell...? MEMORY!!!
Yep, your eyes weren't mistaken! I'm talking about memory! But not any memory, Computer memory! One of the most important types of memory in the whole technology world. If you want to expand your knowledge...come and visit my wiki about the present status of computer memory! It'll be burned in your brain till eternity!
(I will post the link of my wiki when it is complete)

Computer Maniacs!
Do you want to buy a computer?If you do, then read this article. If not then go somewhere else.
A few necessities that you would need to consider when buying a computer are the key components. For example, the key compnents of a desktop computer are as follows:
Processor
o 2.8 GHz processor speed (not terribly relevant to most computer users – exceptions will be "gamers" or those folks who do lots of number crunching)
o Pentium 4 or AMD Athlon (stay away from Celeron – this is Intel’s "low end" processor)
o 2.8 GHz processor speed (not terribly relevant to most computer users – exceptions will be "gamers" or those folks who do lots of number crunching)
o Pentium 4 or AMD Athlon (stay away from Celeron – this is Intel’s "low end" processor)
RAM
o Random Access Memory or "desktop memory" o More RAM can significantly improve your computer’s performance
o Most RAM today is DDR RAM (good for video)
o Older type of RAM is SD RAM or just DRAM
o Cannot "mix" RAM types within the same computer
o When buying a new computer today, look for 256 MB of DDR RAM or even better, 512 MB DDR RAM
Hard Drive
o This device is where all of your programs are stored
o Look for 80 GB of HD
o To put things into perspective....
Floppy disk = 1.44 MB memory
Thumb drive with 128 MB memory = 80 floppy disks worth!
CD = 700 MB memory (about 420 floppy disks worth!)
1000 MB = 1 GB
Monitor
o CRT: "Cathode Ray Tube"
"Big and bulky" monitors
Labeled size is less than the viewable size: 17" labeled size is 16" viewable.
Very cheap. Expect to pay $100 to $300 for a 17" labeled size.
o LCD
Very thin
Fabulous resolution and color
Labeled size is the same as the viewable size.
Expect to pay $250 - $300 for 15" and $400 - $550 for a 17".
Look for a long (3 year) warranty.
o Decide if you want speakers "built-in" to the monitor or if you want separate speakers (which typically sit on your desk area).
o Random Access Memory or "desktop memory" o More RAM can significantly improve your computer’s performance

o Decide if you want speakers "built-in" to the monitor or if you want separate speakers (which typically sit on your desk area).
Ports
o Look for 4 USB (2.0) ports on the backside of the computer with a minimum of 2 USB (2.0) ports on the front side
o If you have a digital camera with memory card, a card reader built in to the computer is handy (however, a separate card reader only costs about $20).
o Ethernet 10/100 LAN port: essential if you have cable or DSL modem
o 56K dial up modem (slooooooooooow but cheap internet access)
1
Mouse
o Optical mouse
Excellent tracking
More pricey than the "roller ball" mouse ($40)
Many styles are ergonomic
Can be wired or wireless (both function the same)
Wireless function uses batteries which must be routinely be replaced (the mouse is "on" all the time and uses 2 AA batteries every 3 months).
o Roller ball (track ball)
Very cheap (<$10) Tends to clog with dust over time Keyboard o Can be wired or wireless. o Wireless keyboard and optical mouse combination costs about $80. o Most computers include a wired keyboard and wired track ball mouse at no additional cost. Office Program o The "standard" in the industry is Microsoft Office Professional (Word, Excel, Access, PowerPoint, FrontPage) o Microsoft Office Basic has Word, Excel and Access. o Most new computer systems do NOT include this software – they may include Microsoft Works – this is NOT the same as Microsoft Word. o Free download: Open Office (compatible with all Microsoft Word documents). http://www.openoffice.org/

These are a couple of the components a computer needs. These will give you a great idea on buying a good quality computer that is worthwhile but still keeps your wallet full.

Did someone say PRINTER?
What would we do without Printers?
We couldn't print, fax, scan or copy. But for some people, all these requirements in a printer are not necessary. All this depends on what you are going to need the printer for and where you are going to use it.
For example, some important information you really may need to consider first of all is what you are going to use the printer for? If its going to be for officework, then you should think about getting a printer that has multi-function features like, scanning, copying, faxing and of course printing. For example, the type of printer i have, fits all these needs but isnt too large and bulky, although these printers may be pretty immense and chunky. Some other factors needed to put into consideration are, prices, quality, printer ink, capacity and its speed.
If you dont need a printer for office work, then you should consider something smaller with less features. Like, if you only need it to print documents and images you will need a smaller but is still compact and chic.
After your difficult but thoughtful decision about what you need in your printer, it would be time to decide what type of printing you want. This means whether or not you need an inkjet printer or laser printer. The difference between these two are that a laser printer is more expensive but has clearer printing quality and has polished ink look than a inkjet printer.
I will give a great example of an office inkjet printer, that printer is Epson Stylus CX4700. It has many features:
