My name is Chawannuch Saknarongdech. I was born in 23 August 1991. I am a student at MUIC. My major is TIM and I also minoring in German. I like comics and novels. My first goal is to graduate from MUIC within 4 years and travel around as many places as possible.



The following steps are things that you should consider before buy a personal computer. 1.Motherboard: The Motherboard's FSB (Front Side Bus) speed is an important indicator of a Computer's speed. It is a bi-directional bus that carries all electronic signals to and from the CPU to the components - Hard Disk, Main Memory, etc. The faster the FSB, the faster your Computer! Today's fastest FSBs come at speeds above 1 GHz!

2.Processor: Currently, the following Intel Processors are available: 1.Intel Core i3 Processor, with the 540 and the 530 Product Numbers 2.Intel Core i5 Processor, with a variety of Product Numbers 3.Intel Core 17 Processor, again with a variety of Product Numbers available under it

3.Hard Disk: Current technologies here are ISA and SATA, with Hard Disk speeds being 5400 RPM, 7200 RPM and 10000 RPM. Of the two technologies, SATA is faster and costlier. Today's Hard Disks come with capacities of 320 GB and even 500 GB!

4.Main Memory: •you will need at least 2 GB Memory. Today's Computers come with 2, 3, even 4 GB Memory!

5.Graphics and Sound: All Motherboards today come with built-in Graphics and Sound. This was not the case earlier. However, the Graphics and Sound that is built into the motherboard is very basic. 1.Most of the graphics-intensive programs - AutoCAD, CorelDRAW and the like, would run much faster with an add-on Graphics card with dedicated memory. In fact, many of today's graphics-intensive games would not even start playing, on the built-in graphics or sound card! This is because before starting up the game, the game would look for a dedicated Graphics Card. If it does not find any, it would not start up! So if you plan to run more that a Word processor, e-Mail, Browser and such stuff, a dedicated Graphics Card such as nVIDIA or Radeon, with 512 MB or even 1 GB of dedicated Video RAM is a must!

6.Optical Drive: Today, you have a choice of Optical Drives. Here are the choices you have: 1.CD-ROM Drive (Read CDs) 2.Combo Drives (Read and Write CDs, Read DVDs) 3.Super Drive (Read and Write CDs as well as DVDs) 4.Blu-Ray Drives (Read and Write CDs, DVDs as well as the new Blu-Ray Disks)

7.Operating System: Lastly - and equally importantly, your choice of Operating System will also affect your specifications. While Windows XP would run quite well with 512 MB Memory, you will require a minimum 1 GB, if your choice is Windows Vista Business: we recommend 2 GB RAM if you are choosing a machine running Vista Home Premium, Vista Business or Vista Ultimate. Interestingly, the latest version of Windows, Windows 7, requires less in terms of Memory, than its predecessor, Windows Vista! However, we recommend that you still go for 2 GB Memory, if your new Machine has Windows 7 on it

IPHONE 4 Build and design - At 9.3mm thick, the new iPhone is 24 per cent slimmer than the iPhone 3GS, and Apple claim it's the "slimmest smartphone on the planet.” It’s built with stainless steel and glass for strength and scratch-resistance.

Processor - Apple’s bespoke A4 processor nestles within the new iPhone’s innards. It’s the same as is found in the iPad and provides super speedy operation and quick multi-tasking.

Operating system - The recently renamed iOS 4 brings much sought-after multi-tasking, the ability to organise apps into folders, the iBooks store, threaded email and the new iAds in-app advertising platform to the phone. iOS4.1 which has just been launched, adds uploading hi-def video over Wi-Fi, High Dynamic Range photos, and a Game Centre for multiplayer gaming. Multi-tasking - Double tap the home button to see a list of recently used apps and switch between them. Crucially this means you can listen to third-party music apps (like Spotify) or receive VoIP calls while using other programs.

Display - Apple calls it the ‘Retina Display’- it’s 3.5 inches and has a resolution of 960x640 pixels, four times more pixels than the iPhone 3GS. With 326px per inch and an 800:1 contrast ratio, it's been lauded as better than OLED.

Battery life - A bigger battery, coupled with the Apple A4 processor's efficiency, make for claims of 7 hours 3G talktime, 6 hours 3G browsing, 10 hours WiFi browsing, 10 hours music, 40 hours of music, and 300 hours of standby.

Connectivity - Connectivity is Quad band hspda/hsupa, giving a potential 7.2mbps down, 5.8 up. An 802.11n Wi-Fi chip will provide blistering speeds when in range.

Camera(s) - The camera’s had a major beefing. This time there’s a 5-Megapixel cam on the back with a backside illumination sensor and LED flash, plus a VGA cam on the front for the new ‘FaceTime’ video calling feature. It’ll also shoot 720p HD video at 30fps.

Data storage - 16 and 32GB models are available

Apps - You know the drill; paid and free apps from all and sundry on the App Store. At the time of writing there are around 225,000 apps. Apple tightly controls what makes it in.

Special features? - The new iPhone benefits from the iMovie app ($4.99) that lets you extensively edit and upload videos on the phone. There’s also a built in Gyro, for 6-axis motion-controlled gaming, plus a dual mic with noise suppression tech built in. Apple thinks its FaceTime video calling feature will “change everything.”

 HTC Desire

Build and design - HTC Desire: A simple, understated but ultimately classy design, built with a rubberized plastic back to be reasonably tough. The new optical track pad eschews the trackball for slimness and aesthetics, while tactile buttons at the bottom feel better than the Nexus One’s touch-sensitive ones.

Processor - The increasingly popular Qualcomm SnapDragon processor gifts the Desire 1 GHz of power, making it extremely swift.

Operating system - The Desire ships with Android 2.1, but is soon to get the ‘Froyo’ 2.2 update. According to reports, this will make it 450% quicker, allow you to store apps on the MicroSD and gift support for Flash 10.1 during web browsing.

Multi-tasking - The Android platform supports multi-tasking like a champ, letting you easily switch between several running apps. Heavy multi-tasking does take its toll on the battery life, though.

Display - A 3.7-inch AMOLED screen that provides pin-sharp detail while not being too power hungry. Being OLED, it can prove hard to read in bright daylight.

Battery life - 400 minutes of GSM talk time, 390 over 3G. HTC claim the Desire has 390 hours standby time.

Connectivity - Near identical. HTC say the Desire boasts a 7.2 Mbps download speed and 2 Mbps upload speed over 3G. The Wi-Fi chip is the same as the iPhone: 802.11 b/g.

Camera- The Desire sports a very impressive 5-Megapixel camera with LED flash. Video and images aren’t HD, but it’s certainly up there with the best smart phones around.

Nokia N8

Screen - The Nokia N8’s 360 x 640 pixels 3.5-inch touchscreen is extremely adequate and, as is the case with a lot of Nokia devices, there’s the option to watch videos on your TV via your phone, which is a lovely little touch – and lessens the necessity of having an immaculate screen.

Camera - Nokia knows how to do cameras, with even its low-end devices usually sporting a 5-megapixel Carl Zeiss camera. And, predictably, the Nokia N8 is no exception to this rule and features a massively powerful 12-megapixel camera and Xenon Flash. In short, the Nokia N8 will take some seriously impressive snaps.

Operating System - The Nokia N8 is powered by the new Symbian^3 OS and, while it may have ironed out a lot of the niggles, such as constant confirmation requests, it still remains to be seen whether or not it’ll stand tall amongst the Android and, more importantly, iPhone 4s of the world.

What I choose between Iphone4, HTC, and Nokia? If I have to choose one of these three devices, I will choose Iphone4. IPhone 4 uses IPS technology which also used in IPAD and with a high pixel resolution of 640 x 960, no human eyes can ever distinguish any dot pixels on the screen. The HTC Desire and Nokia N8 also have high resolution, but iphone 4 is definitely the winner, in my opinion. Moreover, these three types of smart phones are also similar in terms of camera, but iphone 4 can record 720p HD video. One of the uniqueness that I really like about iphone is its iPod integration features. However, one of the main reasons why I choose iphone 4 is its outside look. Iphone 4 is one of the world thinnest smart phones, but it also has a good shape and looks very modern to me. It comes with the memory of 16 GB or 32 GB, so I do not need to but extra expansion memory like in HTC or Nokia N8. Speaking of application, my favorite is going to be iphone because the Apple Stores has nearly five times as many apps as HTC and Nokia. I used to have Nokia n7, but there is so limited of free apps. Moreover, one thing that I love about the Apple App Store is the ability to browse the store on our PCs and side-load apps to the phone. Another thing that I love about Apple is its protection from viruses. As I said earlier that I once used Nokia N7, I went online and received viruses that I had to take it to the Nokia shop to fix. According to my research, HTC also runs window program which possible for viruses. Nokia N8 doesn’t have front camera, and even though HTC has a front camera, Iphone4 is much better in terms of pixels.
