Vector vs Bitmap

Vector vs Bitmap ? its two different data formats. Bitmap used as a lifetime picture and Vector is commonly used for something abstract like logos. From my observation, bitmap is using a pixel taken from a digital camera or scanner, but vector is not used pixel it use mathematical description. Mathematical description is based on how it drawed by a person and change it into a picture. Other than that, bitmap usually save in a huge depends on size file but vector created in a small file no matter how size it is.

Filename Extension and Intended Purpose

  1. Listed the most common formats
  2. Identify their purpose

 

Answer :

.gif = stands for “Graphic Interchange Format”. GIF can store image in small size without downgrade the quality of image.

.jpeg = JPEG image mostly is a lossy compression. JPEG can be setting to enlarge or to decrease the size of the picture but some color would be loss.

.png = stands for “Portable Network Graphic”. PNG is a loseless image same like GIF so it will not be blurred when it goes to JPEG.

.pdf = stands for “ Portable Document Format”. It can be use as multipurpose such as view multiple page and stored a lot of numbers of pages.

Data and Compression Techniques

  1. Discuss the differences between analog data vs digital data.
  2. Discuss two type of compression techniques; lossy and loselss compression.

 

Answer :

1. There is differences between analog data and digital data. One of the differences is signals which is analogue data shows that the signals is repetitive in physical measurements form but digital data signals is yet repetitive but its discrete in time which is digital modulation form.

2. There is two types of compression techniques such as lossy and lossless compression. This two techniques has the same reason of function but it works in a different way. Lossless can be implement by using coding method as the idea to access any transmition or storage in smaller form. Lossy is spatialy domain encoding which is definitely deleting unimporant bits of information to reduce the number of bits to become smaller.

2) Cyberlearning ability is great experience in learning process. By using cyberlearning, student can come to class without going to a campus. Cyberlearning ability in classroom shows a benefit towards the teacher and students. By preparing any media such as video and audio helps the student to understand more rather than traditional method. Teacher also used information in internet as a supporting point on the lesson.

3) i) Audio and Video editting tools 

This tools provide a range communication towards the teacher and student. It allows teacher to communicate clearly with the students. Audio and Video tools provide teacher using an audio editor and video editor for a computer.

ii) Blogging

It allows a teacher to communicate with student in visually. By updating a question or a statement in web, student may discuss the topic given by a teacher. For example using wordpress as a tools of learning between teacher and student.

iii) Mind Mapping

By creating a creative mind map using web 2.0, it can attract the student in learning. There is a lot of intractive mind mapping tools in web 2.0. Teacher able to draw a simple and fun mind mapping to make student like to gain knowledge.

4) Social networking can make student engage one with another very quick by virtually without using any cost. It is important because student will developing a communication skills by using social network. Another good impact is student are using educational tools such as blogger to interact with other people. Discussion can be made by replying on the web blog sites with teacher or among friends. For my opinion bad thing is happening alot than good thing. This is because usually social network is the main causes student fail in examination. Alot of time consuming, social network distract the focus of the students towards study and learning process.
