What are the three phenomena of computing
Hardware- Computers are the physical embodiment of computation
Software- applications on a computer that instruct it to do certain things
The experience- Hardware and Software present a virtual world that doesn't exist but we still experience.
What are some (at least two) new problems that have risen with these three phenomena of computing and why?
Online bullying and scams are two large problems that have risen with the three phenomena. They exist simply because it is an artificial world that doesn't really exist.
Try to define (in your own words) what a program is and give an example (not use any code)
Made up of algorithms and written in a specific programming language ex: python
Try to define (in your own words) what a software is and give an example.
Software instructs the computer by providing the steps needed to perform a task
What is data is in Computer Science means? Give two (2) examples of data.
Data in the physical form is everywhere, but we convert it digitally with 1's and 0's. Examples of data are News papers and magazines
Try to define (in your own words) what an algorithm is and give an example of it
a systematic method to producing a specific result. an example could be the steps to making a sandwhich.
Explain two very good reasons why it is important to know the right IT (Information Technology) terminology?
Everyone needs and uses IT and tech support, and tech support can't help you without the right word. Also, to learn a new subject, we must learn its terminology.
The main computer components and their functionalities (give examples)
Motherboard connects everything together. Power supply supplies all the components w power. CPU is the brain of the operation, it performs the calculations needed by a system, and it can vary in speed.
The two types of computer memories, their functionalities and an example for each one.
Main memory is a RAM, which is where a program is stored while running. Volatile memory is when contents get erased when a computer turns off.
High level programming language and give an example.
Allows simple creation of powerful and complex programs, ex: python
Low level programming language and give an example.
close in nature to machine language, ex: assembly language
Machine language and give an example.
impractical for people to write in machine language, ex: 01010101010101
Main characteristics of any high level programming language
No need to know how CPU works or write large number of instructions, also closer to English and algebraic expressions
predefined words used to write program in high-level language
perform operations in arithmetic data
Syntax error and semantic or logical errors
syntax errors prevent code from being translated. Syntax errors are much easier to fix rather than semantic or logical errors.
