30th September 2009
Time always passes so fast. This is my last blog for technology communication class. N soon, the exam will coming up. Oh, kinda worried… well, in this blog, we were asked to share about 10 most frequent use short form in sms because today topic have learnt about sms. I tink different languages oso have its own short form rite? For me, the most frequent short form I use in sms is like:
Tq: thank you, Gd morning: Good morning, Beta: better, Kinda: kind the, Thgs: things, 2nite: Tonight, N: and, Tis: this, Tat: that, Wat: what….
Well, here are just 10 examples that I usually used n there is still many short form words can be use in sms. With this short form, I can save my space to type more words n type faster… I tink tis is d benefits 4 me. ^.^

RCA connector...13Sept2009
What's RCA connector??? An RCA connector is a type of electrical connector that is commonly used in the audio/video market. The name "RCA" derives from the Radio Corporation of America, which introduced the design by the early 1940s to allow mono phonograph players to be connected to amplifiers. For many other applications it began to replace the older jack plugs used in the audio world when component high fidelity started becoming popular in the 1950s. The corresponding plug is called an RCA plug or phono plug, for "phonograph". The name "phono plug" is often confused with a "phone plug" which refers to a jack plug or TRS connector.
There are lot of different usage of RCA connector. In the most normal usage, cables have a standard plug on each end, consisting of a central male connector, surrounded by a ring. The ring is often segmented for flexibility. Devices mount the jack, consisting of a central hole with a ring of metal around it. The ring is slightly smaller in diameter and longer than the ring on the plug, allowing the plug's ring to fit tightly over it. The jack has a small area between the outer and inner rings which is filled with an insulator, typically plastic (very early versions, or those made for use as RF connectors used ceramic).
As with many other connectors, the RCA has been adopted for other uses than originally intended, including as a power connector, an RF connector, and as a connector for loudspeaker cables. Its use as a connector for composite video signals is extremely common, but provides poor impedance matching. RCA connectors and cable are also commonly used to carry S/PDIF-formatted digital audio, with plugs colored orange to differentiate them from other typical connections.
Connections are made by pushing the cable's plug into the female jack on the device. The signal-carrying pin protrudes from the plug, and often comes into contact with the socket before the grounded rings meet, resulting in loud hum or buzz if the audio components are powered while making connections. Continuous noise can occur if the plug partially falls out of the jack, breaking ground connection but not the signal. Some variants of the plug, especially cheaper versions, also give very poor grip and contact between the ground sheaths due to their lack of flexibility.
They are often color-coded, yellow for composite video, red for the right channel, and white or black for the left channel of stereo audio. This trio (or pair) of jacks can be found on the back of almost all audio and video equipment. At least one set is usually found on the front panel of modern TV sets, to facilitate connection of camcorders (through 3.5mm Jack to 3 RCA, also called Mini RCA plug), digital cameras, and video gaming consoles. Although nearly all audio-visual connectors, including audio, composite and component video, and S/PDIF audio can use identical 75 Ω cables, sales of special-purpose cables for each use have proliferated. Varying cable quality means that a cheap line-level audio cable might not successfully transfer component video or digital audio signals due to impedance mismatch and poor shielding quality (causing signal-to-noise ratio to be too low). Cables should meet the S/PDIF specification as defined by the international standard IEC 60958-3 for assured performance.

telecommunication@ 9 Dec 2009
Today is also about telecommunication but it's talk about the Facsimile System and Paging System.
Facsimile is also known as fax in short. The word of facsimile come from Latin fac simile which mean "make similar" or "make a copy". It's a telecommunications technology used to transfer copies of documents, especially using affordable devices operating over the telephone network.
A "fax machine" usually consists of an image scanner, a modem, a printer, and usually a phone combined into a single package. The scanner can converts the content printed on a physical document into a digital image. The modem used to send the image data over a phone line to another device and the printer at the far end produces a copy of the transmitted document.
I like fax machine so much especially when i need to print some document in an emergency moment.
A pager which also can called a beeper, is a simple personal telecommunications device for short messages. There are three types of pager which is numeric pagers, alphanumeric pagers and two-way alphanumeric pagers. Numeric pagers are the simplest of the type of devices offering only a numeric display of the phone number to be called and pager codes. Alphanumeric pagers are essentially modified versions of numeric pagers with sophisticated display to accommodate text. These devices are usually given an email address to receive text messages. Two-way Alphanumeric pagers are alphanumeric pagers with the ability to send text messages typed in with a small keyboard. I still remembered my dad had the first type of pager when i was in primary school but he didn't use it anymore after he bought his first handphone. It's too pity because we didn't keep the pager. Haiz...

telecommunication @ 6 Dec 2009
Today, we learnt about telecommunication which include the part of telephone system and cellular phone system.
The word telephone is actually from Greek word. Tele means a far distance and phone means voice. Telephone is a telecommunications device that is used to transmit and receive sound.
I think every families must have a telephone in their home nowadays because it's a common device in today world. For me, my house telephone is very important because i cannot contact with my family without it. Although my family have their own cellular phone but the line are not stable in my house area. So, that's why i felt that it's important.
Cellular phone system is also known as the mobile phone or mobile, also called a wireless, cellular phone, cell phone (AKA: cellphone), cell or hand phone (HP). I still remembered my 1st hp is nokia when i'm form 2. It just included some simple function but now it's much more high technology already because it also including 3G, bluetooth, wap and so on...

RAZAKsat @ 2nd Sept 2009
RazakSAT is a Malaysian satellite carrying a high-resolution camera. It was launched into low Earth orbit by a Falcon 1 rocket on July 14, 2009. It was placed into an unique near-equatorial orbit that presents many imaging opportunities for the equatorial region.
This satellite is Malaysia's second remote sensing satellite after TiungSAT-1, which was launched in September 26, 2000 on a Ukrainian Dnepr rocket from Baikonur, Kazakhstan. Originally called MACSAT, RazakSAT's payload is mainly electro-optical, carrying a Medium-sized Aperture Camera (MAC) which is a pushbroom camera with five linear detectors (one panchromatic, four multi-spectral) weighing approximately 50 kg. The entire satellite weighs at about 180 kg.
The then-Prime Minister of Malaysia, Mahathir Mohamad renamed the satellite to RazakSAT in tribute to the second Prime Minister of Malaysia, Abdul Razak or known as the "Bapa Pembangunan Malaysia" (Father of Malaysian Development) for his contribution to Malaysia's development. This was held officially during Mahathir's working visit to Astronautic Technology (M) Sdn. Bhd.
(ATSB) in 2003 at its premise in Technology Park Malaysia (TPM) in Bukit Jalil, Kuala Lumpur. It has since moved to its new premises at Hicom-Glenmarie Industrial Park, Shah Alam, Selangor. ATSB is a wholly-owned company of the Minister of Finance Inc. (MOF) and reports to the Ministry of Science, Technology and Innovation (MOSTI), Malaysia.
RazakSAT's mission plan will be carried out by engineers from ATSB. Control operations will be conducted through Malaysian National Space Agency 's Ground Station in Banting, Selangor and ATSB's ground station in Shah Alam, Selangor consisting of a Mission Control Station (MCS) and Image Receiving and Processing Station (IRPS). Another Malaysian ground station which would be able to receive images from the satellite is the Remote Sensing Malaysia groundstation in Temerloh, Pahang. The IRPS will receive and archive images for post processing and distribution to the users.
RazakSAT is unique as it will be the first microsatellite of its class to be placed at Near equatorial orbit (NEqO); unlike many other satellites of its kind that are placed on Sun-Synchronous Orbit (SSO). RazakSAT's orbital inclination will coincide with the latitude of its launch at Kwajalein, and that of the northernmost extent of Malaysia. Thus its launch will be nearly due east and quite efficient.
This is especially important because Malaysia is usually covered by the equatorial cloud bands. Normal sun-synchronous optical satellites, which may re-visit an area only once every 14 days, will almost never be able to see the ground during their pass. As a result, much optical imagery of Malaysia is years out of date.
Razaksat, on the other hand, will revisit some part of Malaysian territory every 90 minutes, maximising its ability to exploit gaps in the clouds, and substantially improving coverage of the country as a result.
