computers

what is a string

• a word, number, or letter encased in quotations

• a routine that is given some data as input and that will calculate and return an answer based on that data.

• one of the simplest and most widely known encryption techniques.

• a coding system using the binary digits 0 and 1 to represent a letter, digit, or other character in a computer or other electronic device.

what is the purpose of a function

• store data

• simplify code by not having to repeat the same code multiple times

• represents text, computer processor instructions, or any other data using a two-symbol system

• transfer information through multiple routers

what is a computer

• an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program:

• a large, motorized machine equipped with a metal blade to the front for pushing material: soil, sand, snow, rubble, or rock during construction work

• a coding system using the binary digits 0 and 1 to represent a letter, digit, or other character in a computer or other electronic device

• a data type and is often implemented as an array data structure of bytes(or words) that stores a sequence of elements, typically characters, using some character encoding

a ceaser cipher and substitution cipher do the same thing

• true

• false

a byte is 20 bits

• false

• true

which of these is not a language used to code

• JavaScript

• Python

• Perl

• swiftie

which of these is a form of malware

• computing innovation

• binary code

• keylogging

• bytes

phishing

• the use of a program to record every keystroke made by a computer user in order to gain fraudulent access to passwords and other confidential information

• a technique that attempts to trick a user into providing personal information. That personal information can then be used to access sensitive online resources, such as bank accounts and emails

• a wireless access point that gives unauthorized access to secure networks.

• a process that reverses encryption, taking a secret message and reproducing the original plain text.
