The purpose of this assessment is to investigate concepts relating to a system that is used within a digital device. For my assessment, I chose the A5158 model MP3 player that belongs to my dad.
The features of this device include:
High-Contrast LCD Display, Resolution 96 x 32
Integrated Flash Memory
Plays MP3 and WMA Digital Music Files FM Radio
4GB – Stores up to 1000 songs
USB 2.0 Hi-Speed for fast file transfers
Key lock preventing accidental key presses
Integrated 100mAh Lithium rechargeable battery – for up to 5 hours playback
Data Representation
In computer terms, a bit is a numeric value - either a zero or a one - that holds a single unit of digital information. Bits are usually strung together in a sequence - eight bits normally equals one byte. Bits are used to write binary numbers, which can be used to store decimal numbers such as 244 or 93 as patterns of ones and zeroes.
ASCII - or American Standard Code for Information Interchange - is a computer code that was developed to allow computers to convert human text into bits that computers could understand. In ASCII code, for example, the letter A is 65 - a number that can then be converted into the binary value 1000001.
In the 1960’s, the 7 bit ASCII table was first adopted. Within a 7 bit number, 128 different characters can be stored - English letters from A-Z (upper and lower case), numeric digits from 0-9 and “special” characters such as !/*+. The eighth bit was used to detect transmission errors.
The origin of code switching can be traced back to multiple scenarios. Around the 1860s slaves were declared free in America. W.E.B Du Bois and Anna Julia Cooper were firm believers that who embraced assimilation and saw higher education as the cure-all to racialized problems. Du Bois, in particular, is famous for his assertion that it would be the “Talented Tenth” of the race who would lead blacks to a better life.
Out of a total from 26 sequences only 6 were made up of 4‘s while 20 were composed of different structures of 2‘s. This tells us that 77% of the asci showed crossing over while 23% did not.

An MP3 is a recorded high-quality audio (voice and music) file which can be distributed over the Internet, and played on any multimedia computer with the right sound card and speakers. MP 3 is simply a file format that compresses a song into a smaller size so it is easier to move around on the Internet and store. MPEG is the acronym for Moving Picture Experts Group. This group has developed compression systems used for video data. For example, DVD movies, HDTV broadcasts and DSS satellite systems use MPEG compression to fit video and movie data into smaller spaces. The MPEG compression system includes a subsystem to compress sound, called MPEG audio Layer-3. We know this as MP3.
ASCII is coding system for letters and numbers. Each character has its own number for example the ASCII code for A is 097, A In binary is 01100001 we can work out the ASCII code by using its binary number
From the textbook, we are shown five examples of coding methods, with three explained in deeper detail. They are the Extended Binary Coded Decimal Interchange Code (EBCDIC), the American Standard Code for Information Interchange (ASCII), Unicode, International Alphabet 5 (IA5), and International Organization for Standardization (ISO). Each of these coding methods are different, but do have some similarities. ASCII was the standard coding method used due to vendors using it as the bases for their devices for so many years. Unicode is special due to being made as the multilingual coding method. It borrows from other coding methods to generate a code that can be deciphered by most major technology based regions around the world. It uses ASCII as part of its bases, which allows user to translate ASCII based programing code into
A bit is a single number or a single value which can be either 0 or 1 and this value is represent the digital information. A byte is a sequence of bits; like a sequence of digital information, usually eight bits equals to one byte.
Char type is so useful. Char are the values type. This means they are located in the bytes and bites on the evaluation stack. You can get single char from a string variable. Char another data type that is useful to programmers.
The code assigned letters in the alphabet and numbers a set of dots (short marks) and dashes (long marks) based on the frequency of use. The code used the English alphabet but they would make the more frequently used letters into the less complex dots and dashes, such as E or A. While the Less frequently used letters such as D or Z got a lot more complex code of dots and dashes. Initially, the code, when transmitted over the telegraph system, was rendered as marks on a piece of paper that the telegraph operator would then translate back into English. Rather quickly. But then the operators became so good at translating the messages that they could just understand the messages just from clicking of the code from

The Assembler for the VIC-20 was written by Don French and published by French Silk. At 1,639 bytes in length, its author believes it is the smallest symbolic assembler ever written. The assembler supported the usual symbolic addressing and the definition of character strings or hex strings. It also allowed address expressions which could be combined with addition, subtraction, multiplication, division, logical AND, logical OR, and exponentiation operators.
In today’s world it is a requirement to be digitally literate in order to be able to function in a capacity that enables one to be more successful whether it is at home, school, at our jobs or even looking for a job. Over the last few decades our environment has evolved into a digital environment. Being or becoming digitally literate is essential in being successful in this digital environment. Almost everything we do today requires some sort of digital knowledge or literacy. From surfing the internet to searching for a job to being able to perform our jobs, we are required to have some sort of digital
“Currently we live in an era driven by information, global competition and new technologies that are changing the way we think, live and work.” (Pillay, Boulton-Lewis & Wilss 2004, p.17). This conveys the notion that technology has manipulated the minds of today’s generation in every way possible, could be during schooling and non-schooling life. Hence in order for one’s teaching style to go successful one should teach in accordance to the characteristics of the generation they’re teaching as today’s generation requires a digital pedagogy. Furthermore this essay scrutinizes how the characteristics of the 21st century and the digital world will influence the type of teacher one hopes to become. As well as it examines on the construction of skill development towards students from the trending of digital fluency.
