Memory is a major part of computers, as with humans too ; ) Without memory where would we store extra data and where does it go when we store it? Memory is stored in 3 category of items. The byte is the basic storage unit. The byte are what trans mitts the memory from other storage devices and the data is what exists as "byte".
Memory size will determine the number of bytes, as mentioned above, how much available storage can be held. The terms are very obvious abbervations such as Kilobye is equal to a thousand bytes holding about 1/2 pgs if text , Megebyte is equal to about one million bytes holding about 500 pgs of text, Gigabyte 1 billion holding 500,000 pgs of text and lastly Terabyte 1 trillion holding 5000,000,000. There are many types of memory, some being volatile memory meaning its loses its data when computer is turned off and Nonvolatile memory being there permenat even when computer is off. There are also many types of removable memory devices for example, flash memory cards, usb, pc cards and express card modules.

What i Learned about computers
Today i learned about the roles of the computer system units and different processors. A system unit is a case that contains the electronic components of the computer used to process data.Devices may include keyboad, mouse, printer. phone, flash drive, digital camera, phones and laptop.
The processer interperts and carries out the basic instructions that operates a computer. There are differents kinda of processor such as multi core processor quad core and dule processor acting as a better way to speed things up and increase overall proformance.
I also learned what role the "mother board" plays. The mother board system is the main circuit in the unit. The mother board allows slots for extra needed memory and for adapters and expansion slots.

What i learned about computers
Microsoft word is not as easy as i thought it was. I had trouble with the project last saturday because i really don't use it much except for writing simple documents and check spelling. I learned how to use bullets, create different shape pictures, insert images from the web, use borders and highlight text using different fonts. This new knowledge can really help with me with lots of things other then school.
It was self explanitory using the book, it told me exactly how to locate each item , while doing so i also played with some of the other gadgets microsoft has provided, such as clip art, doudle spacing, smart art, and charts.

Pros and Cons
Make a blog entry: pros and cons of a software application in one of the following categories: project management, geo-spatial information, customer relationship management, content management system or a document management system.
The benefits of the project management is really to help validate business initiatives, fully utilize their resources, and enjoy real-time visibility into project status. Project management covers software such as scheduling, cost control and budget management, resoure allocation, collabration software, communication, quality management and documentation or administration systems, which are used to deal with the complexity of large projects.
The software is a great source for many businesses but it does come with some cons, such as fully understanding the software to accuratley use the product, additional features may be so complicated to use, software does not make a clear distinction between the planning phase and post planning phase, limited flexability as to use it to certain tasks and Dealing with uncertainties in the estimates of the duration of each task. However, if correctely used the pros out weigh the cons.
