Unit 28 + 30 Assignment 3 Task 3 – Discuss the impact that file formats, compression techniques, image resolution and colour depth have on file size and image quality. Description Impact on file size Impact on image quality File formats The file format is just how this individual piece or multiple pieces of information are encoded for stored and named. They are a number of different file formats and they are used to store different types of information such as JPEG’s are used to store photos or other images and PDF’s are used to store written documents. In addition to these there are mp3 or mp4 that are used to store audio files. The different formats used to store information will have varying file sizes. This is because some files
In Peter Singer’s 1972 post titled “Famine, Affluence and Morality”, he conveys that wealthy nations, for example the United States, has an ethical duty to contribute much a lot more than we do with regards to worldwide assistance for famine relief and/or other disasters or calamities which may happen. In this document, I will describe Singers objective in his work and give his argument with regards to this problem. I will describe 3 counter-arguments to Singer’s view which he tackles, and after that reveal Singer’s reactions to those counter-arguments. I will explain Singer’s idea of marginal
Editing and communication: Traditional file systems are cumbersome in that they do not allow users to easily edit files or send information to others. Paper files often cannot be edited directly, forcing users to make new copies to update old files.
Brazoria County, Tx is located just south of Harris county, extending from Houston to the Gulf of Mexico. It includes the cities of Pearland, Manvel, Alvin, Angleton, Sweeny, Lake Jackson, and Freeport. Of these, Angleton is the county seat, but Pearland has the greatest population (City-data.com, 2015). As of 2012, Brazoria County contained a population of 77% urban and 23% rural (City-data.com, 2015). Of the residents of Brazoria County, 63% are between the ages of 18 and 64 (United States Census Bureau, 2010). The leading causes of death for the county are heart disease, cancer, motor vehicle accidents, diabetes, and
2. The larger format increases both the range of values that can be represented and the precision of large and small values. Processing data represented in a larger format requires more complex circuitry and more time for executing the codes. Either of them will slow the program execution.
2. Data compression/decompression results in faster transmission by reducing the amount of space the data
On the other hand, in computer file-based system, the structure of data items are built into the individual application programs. Thus the data is dependent on the data file and vice versa.
One file — All the information from your database is saved into one file. This limits options and how you choose utilize data; slowing down reports, queries, and forms. Its performance becomes slow as the user scales data size. Multimedia data can use up MS Access limited space quickly.
The Bitmap Graphic format files uses cameras, scanners, and graphic software format extensions which are BMP, RAW, TFF, GIF and PNG.
There are multiple image file formats that are supported by Image class. Each supported format is defined as a static property in ImageFormat class in namespace System.Drawing.Imaging (MSDN, n.d.-d).
As we’ve increased collection of data, the complexity of data has also risen. Much of the data we use is not in the above, unified format. Multi-file database links different data formats together and allows a more flexible way of organising and using data. It provides users with the ability to link between
A file system (sometimes written filesystem) is the method used to control the storage and retrieval of data on a storage medium. (4) It determines the way in which ‘files’ are named and how they are logically organised on a disk or partition. (5) Without a file system, data held on a storage medium would be one large block, with no method of determining the location of specific pieces of information. By separating the data into identifiable blocks, the information can be easily located. (1) Each grouping of data, which takes its name from the method of organising paper-based information, is referred to as a “file”. The file system is comprised of two specific parts: a collection of files and a directory structure, which provides data
Databases always keep data as it stores it making the data more efficient and all the different types of data are generally categorised as a specific data type.
Multimedia data include structured data and non-structured data such as audio, video, graphs, images and text media. It’s used to provide query processing, update processing, transaction management and Meta data management,security and integritydynamic storage organization
The amalgamation of multimedia data types from numerous sources uniquely characterizes multimedia information systems. The data types found in a typical multimedia database include:
The use of recent and modern multimedia devices which is connected to the internet like scanners, cameras, and especially smart tabs and cell phones made capture, storing, transmission, and sharing of a huge amount of images, songs, and videos much easier and faster
