Answer 9

The term “open source” refers to something that can be modified because its design is publicly accessible.

Question 10

What is string?

Answer 10

A string is a data type used in programming, such as an integer and floating point unit, but is used to represent text rather than numbers.

Question 11

What is char?

Answer 11

It is short for character, which is a data type that holds one character (letter, number, etc.) of data. For example, the value of a char variable could be any one-character value, such as ‘c’, ‘4’, or ‘#’.

Question 12

Answer 16

Characteristic of an object.

Question 17

Why do we place comments in the code? Where should we place it?

Answer 17

You can use comments to explain your code, which can help you when you edit the source code at a later date. This is especially useful if you have a lot of code.

Question 18

Enumerations are a constructed data type. Why do we use them? How are they “constructed”?

Answer 18

An enumeration is a data type consisting of a set of named values that represent integral constants, known as enumeration constants. An enumeration also referred to as an enumerated type because you must list (enumerate) each of the values in creating a name for each of them. In addition to providing a way of defining and grouping sets of integral constants, enumerations are useful for variables that have a small number of possible values.

Question 19

Arrays are a data structure. When do we use an array? Why do we use an array? How do you declare an array

Answer 19

In programming, a series of objects all of which are the same size and type.

int[] myIntArray = new int[3];
int[] myIntArray = {1,2,3};
int[] myIntArray = new int[]{1,2,3};

Question 20

How is machine code different from high level language?

Answer 20

The lowest-level programming language (except for computers that utilize programmable microcode) Machine languages are the only languages understood by computers
a high-level programming language is a programming language with strong abstraction from the details of the computer.

Question 21

What does a compiler do?

Answer 21

A compiler is a program that translates the source code for another program from a programing language into executable code. The source code is typically in a high-level programming language

Question 22

Explain the role of the linker.

Answer 22

a linker is a program that combines object modules to form an executable program.

Question 23

Explain the use of the “Imports” statement in a program.

Answer 23

The Imports statement enables types that are contained in a given namespace to be referenced directly

Question 24

What is ASCII? Unicode?

Answer 24

ASCII is a code for representing English characters as numbers, with each letter assigned a number from 0 to 127.

The Unicode Standard is the universal character encoding standard used for representation of text for computer processing. Unicode provides a consistent way of encoding multilingual plain text making it easier to exchange text files internationally.

Question 25

What does the keyboard do?

Answer 25

The keyboard is the main text input device on most computers.

Question 26

What does the monitor do?

Answer 26

A monitor displays the images and information in visual form, using text and graphics. The part of the monitor that displays the information is known as the screen. The monitor is one of the fundamental output devices of a computer system.

Question 27

What does a printer do?

Answer 27

In computers, a printer driver or a print processor is a piece of software that converts the data to be printed to the form specific to a printer

Question 28

What does a scanner do?

Answer 28

A scanner works very similar to a copy machine, in that it takes photo identical copies of things placed into them and scanned, only for the comfort of use within your own home, without the cost of a full copy machine. Scanners also have the unique ability to scan text documents, and allow you to edit them on your computer, although this is still not 100% foolproof yet, and often gives some errors here and there.

Question 29

What does a mouse do?

Answer 29

A mouse provides an easy point-and-click graphical interface with the computer.

Question 30

What do speakers do?

Answer 30

A speaker vibrates in relation to the electrical signal going to it, turning the electric signal into audible sound.

Question 31

What does a hard drive do?

Answer 31

What does a hard drive do?
Storage is the hard drive’s responsibility. Everything you keep on your computer is on a hard drive. Not just documents, pictures, music and videos. Your programs, your preferences, even your operating system—they’re all stored on your computer’s hard drive.

Question 32

What does a flash drive do?

Answer 32

A flash drive is an electronic small hardware that is normally used in the transfer, backup and storage of data.

Question 33

What does a DVD drive do?

Answer 33

An optical drive which reads DVD discs and transfers their signals electronically to play on a TV

Question 34

What is RAM?

Answer 34

acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and

Question 35

What is ALU?

Answer 35

Abbreviation of arithmetic logic unit, the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison operations.

Question 36

What is a microphone?

Answer 36

A microphone is an instrument that translates sound waves into an electric current, typically fed into an amplifier or a broadcast transmitter. In other words, it is a transducer; it converts audio energy into electrical signals.

Question 37

What does a modem do?

Answer 37

The word “modem” is short for “modulator-demodulator” which is essentially what it does. A computer moves data around on parallel wires by applying one or another voltage to each wire (representing 0’s and 1’s) and the voltage is read at the other end of the wires

Question 38

What does ROM do?

Answer 38

ROM (read-only memory) is a computer chip used to permanently store data in the computer. The ROM is used to store Basic Input/Output System (BIOS) information, which is software that contains information about what hardware devices are on your computer.

Question 39

Memorise the basic block program of a computer and give examples of each component.

Answer 39

You do this one fuck this I’m tired.

Question 40

In computer code what is sequential? Give example

Answer 40

Sequential coding is when each succeeding code is one binary (lol dafuq is binary) number greater than its last.

Question 41

What is conditional coding?

Answer 41

Sometimes a block of code should only be run under certain conditions. Flow control – via if and else blocks – lets you run code if certain conditions have been met.

Question 42

What is iterative coding?

Answer 42

When a process or sequence in a computer program is repeated, this is an iteration. In a computer program, a common form of iterations is a loop, which repeats code to determine values for multiple variables or sometimes just a single variable (adding up multiple values together).

Question 43

What is modular coding?

Answer 43

Modular programming is the process of subdividing a computer program into separate sub-programs.
