Computer Science Final Flashcards
What is binary
Binary is a number system that only consists of 1’s and 0’s to express the values. Binary is referred to as a base 2 number system
How do you put 80 into binary
Step 1: Look at the second roll and see that to make 80 you have to use 64 & 18.
Step 2: On the third roll flip 1 up to 64 and 18 respectively
Step 3: Everything to the left of what you flip up is the number so
1010000
_______ is a system where it converts a binary code into the symbols you see on your screen that are generated by your keyboard
ASCII
What is the internet
is a huge collection of computers arranged in “networks” that are all connected in a way that allow them to communicate with each other.
What is the protocol
hat protocols are rules that a system needs to obey/abide by in order for the system to function correctly.
There are several different protocols in place for computers to communicate depending on how they are connecting to the internet and what they are sending.
What is the computer networks
Computer Networks are clusters of computers that form a type of community of computers.
These groupings make the management of networks and individual computers much easier.
What is the Internet Protocol Address
The IP Address is a unique identifier that cannot be repeated on any 1 network. It is similar to your house address.
If you have a Wireless Internet, or an Internet Router in your home, then you have an home network. How does that work
see google slides
What is DNS
This system translates and IP - 212.34.12.2 to a readable name Yahoo.com
What is a router
Direct Traffic on the internet, trying to find the best path from sender to receiver.
What are variables?
are virtual container used to store a value. This allows the value to be used or transformed at a later time.
What is an event
n Event allows for the interaction with an element in a program.
Events can be prompted by a user:
Click - Item Change - Input - Keypress - Mousemove
What is a function
Function - A coding process for allowing code to be executed repeatedly without having to retype the code. A function call has two parts, the function definition and the function call.
What are loops?
Loop - A coding structure to allow code to run multiple times based on a preset condition. As long as the condition remains true, the loop will continue to run
What is a list
A collection of values assigned to a variable. You can access the list by using the list name and an index number that is assigned to the value. Index numbering starts at 0.
What are conditionals and operators
Condition evaluates for True or False:
if ( 4 < 5){
console.log(“true”)
}
