With the ever increasing technologies available, it is really an uphill task to keep pace with it. I believe that some of you will be getting a new computer soon; esp the new Polytechnic students. A big question you will ask yourself ....
SHOULD I BUY IT FROM SCHOOL OR BUY IT OUTSIDE????
Before we begin to attempt that question, we should first understand the basic components of a computer.
Learning Objectives
- The technologies inside Intel® processors - RAM and Graphics??? - Harddisk : IDE OR SATA
The technologies inside Intel® processors
Clockspeed (Measured in GHz) is a traditional way to identify and choose a processors.
NOW TIMES HAVE CHANGED ... There are many more factors to consider such as;
- L2 Cache - Front Side Bus (FSB) - Hyperthreading (HT) Technology - Dual Core Technology
1.1 - L2 Cache
- Important component to improve overall computer performance
- Memory Storage Area where the computer places frequently accessed data - RAM has a larger area than cache; however slow in accessing data - Larger Cache = allow more data to be accessed faster storage area
1.2 - Clockspeed
- Still an important feature contributing to performance
- Faster Clockspeed = Execution of Instructions more quickly
1.3 - Front Side Bus
- Key Component in contributing to computer's overall performance
- Increase performance and responsiveness between processor to RAM and graphics
- Higher FSB = Application more responsive, improve performance
1.4 - Hyperthreading (HT) Technology VS Dual Core
Hyperthreading (HT) Technology enables 2 threads to be processed in a single core execution ; allowing partially parallel execution
Dual Core enables each thread to be processed in its own execution core (seperate thread) for truly parallel execution

The time of the year has come again ... IT Show 2008 is here
With ever changing technology and faster processors, we can never catch up with it but however, whenever we have the means, we should try "upgrade" parts of our computers to make it more efficient
Here is a guide as to where to purchase certain items
> RAMs (Recommend Kingston) - Best Bargain Computers or Active Foto & Electronics > Ext. Harddisk - Source around 6th floor for best deals (prices may vary frm shp to shp)
> Laptops and Desktops
Buy your laptops on the LAST DAY of the IT Show to get good deals. Prefably at around 7-9pm where most booths will try to sell off their products at a discounted rate. Furthermore, you can request for better upgrades rather than get the "free gifts" which are redundant in most cases.
What to ask for???
- Increase HDD Capacity - Increase RAM - Upgrade in OS - 3 years warranty - Reduce the product price further
SEE YOU ALL AT THE IT SHOW 2008 ... HAVE A GREAT DAY
