introduction of assessment CANON PIXMA MP160

this is canon pixma all-in-ones photo printer.This no-compromise Photo All-In-One,compact and stylish printer. It precision ink nozzles can create high resolution photos that up to 4800 x 1200 color dpi.Other than that,its Microscopic 2-picoliter sized ink droplets produce finely detailed photos.This printer also do not need a computer to connect when want to print the photo.Just capture an image with a PictBridge ready digital camera/DV camcorder, then connect to it and print.As the printer known as "all-in-one",it gives an impressive scans when it produce high-quality scans up to 600 dpi with vibrant 48-bit color depth.There are an advantages when using select Canon photo papers, where can create beautiful photos that last up to 100 years.More than that,we can even copy or scan thick items that do not lie flat on the platen.If we need a smart copying,Dual Color Gamut Technology ensures quality is automatically optimized based on the type of originals you are copying.So.there are too many benefit when we use canon pixma 160 printer as our daily printer.

SUMMARIZING HOW THE GADGET FUNCTIONS

The electromagnet consists of an iron core wrapped with wire, as shown in the figure. During recording, the audio signal is sent through the coil of wire to create a magnetic field in the core. At the gap, magnetic flux forms a fringe pattern to bridge the gap (shown in red), and this flux is what magnetizes the oxide on the tape. During playback, the motion of the tape pulls a varying magnetic field across the gap. This creates a varying magnetic field in the core and therefore a signal in the coil. This signal is amplified to drive thespeakers.In a normal cassette player, there are actually two of these small electromagnets that together are about as wide as one half of the tape's width. The two heads record the two channels of a stereo program.When you turn the tape over, you align the other half of the tape with the two electromagnets.
When look inside a tape recorder, you generally see,two sprockets that engage the spools inside the cassette. These sprockets spin one of the spools to take up the tape during recording, playback, fast forward and reverse. Below the two sprockets are two heads. The head on the left is a bulk erase head to wipe the tape clean of signals before recording. The head in the center is the record and playback head containing the two tiny electromagnets. On the right are the capstan and the pinch roller.The capstan revolves at a very precise rate to pull the tape across the head at exactly the right speed. The standard speed is 1.875 inches per second (4.76 cm per second). The roller simply applies pressure so that the tape is tight against the capstan.

DESCRIBING MAIN AND MAJOR

The Tape
There are two parts to any audio magnetic recording system: the recorder itself (which also acts as the playback device) and the tape it uses as the storage medium.
The tape itself is actually very simple. It consists of a thin plastic base material, and bonded to this base is a coating of ferric oxide powder. The oxide is normally mixed with a binder to attach it to the plastic, and it also includes some sort of dry lubricant to avoid wearing out the recorder.
Iron oxide (FeO) is the red rust we commonly see. Ferric oxide (Fe2O3) is another oxide of iron. Maghemite or gamma ferric oxide are common names for the substance.
This oxide is a ferromagnetic material, meaning that if you expose it to a magnetic field it is permanently magnetized by the field.
The Tape Recorder
The simplest tape recorders are very simple indeed, and everything from a Walkman to a high-end audiophile deck embodies that fundamental simplicity.

DESCRIBING THINGS

I will describe about the tape recorders.it is also call magnetic recording.Magnetic recording is a backbone technology of the electronic age. It is a fundamental way for permanently storing information. In the audio realm, magnetic tape (in the form of compact cassettes) is a popular way of distributing music. People either buy tapes pre-recorded with material, or make their own tapes from cds. In the video realm, video tape is used widely both in the broadcast industry and at home to store material for later viewing on VCR. In the computer realm, magnetic recording is used on floppy disks, hard disks and magnetic tape as the main method for data storage. We'll focus on cassette tapes and tape recorders, but the same technology applies to any form of magnetic recording.

My presentation

Hye everyone..
I want to talk about my presentation last week.For me,i have did my best while present about my topic.
I talk about Enrique Iglesias who is the singer of Latin and English songs. Before i start my presentation,i am really nervous about it. I thought that i will be the worst presenter on that day. It is normal for everyone to feel as i feel.I am so proud of myself because i done mine. While i presented mine, i still can look at the audience eventhough i am so nervous. I also still can use the loud sound for my presentation.

fazrulhisyam's presentation..

a very very good morning to everyone..
i want to give a comment to hisyam presentation last tuesday..
he being a good presenter.he didnt show that he nervous on the stage eventhough he tell me that he feel nervous when he start the present.he also show a good eye contact with the audience.by the way,he broke the time limit.actually,he must use 3 minutes sharp,but he over 10 minutes than he should.furthermore,his slides on the scrin also attracted the audiences to focus on his presentation...he also use attention getter to his audiences like he ask the audiences to cheer the day..thats all..

who is the best and the worse speaker

In my opinionbased on the video that i watched,at the beginning,the video shown not in the correct way,because it is not clear.i can't watched it nicely.so that i didn't know whats the topic about. then when the video started to play,i got that the microasoft guy was the worse presenter.there was to much worse thing that he did,such as he have no eye contact with the audience. he's not look nervous,but he show that he have no mood for the presentation. he just make the gudge feel bored to hear him.he also talk in slow voice.other than that he looks like he forget the content that he want to present..this situation is truly different with mojo.com woman that present her content. she look too confident on herself and she use a good slide for her presentation. her eye contact also can atract the audience.so,i accept her as the good speaker in this session.
