Technical Support Fundamentals

Question 1

What is Abstraction?

Answer 1

To take a relatively complex system and simplify it for our use

Question 2

What is an Algorithm?

Answer 2

A series of steps that solves specific problems

Question 3

What is ASCII?

Answer 3

The oldest character encoding standard used is ASCII. It represents the English alphabet, digits, and punctuation marks

Question 4

What is the Binary System?

Answer 4

The communication that a computer uses is referred to as binary system, also known as base-2 numeral system

Question 5

What is a Byte?

Answer 5

A group of 8 bits

Question 6

What is Character encoding?

Answer 6

Is used to assign our binary values to characters so that we as humans can read them

Question 7

What is a Computer?

Answer 7

A device that stores and processes data by performing calculations

Question 8

What is Cryptography?

Answer 8

The overarching discipline that covers the practice of coding and hiding messages from third parties

Question 9

What is the Decimal form - Base 10 system

Answer 9

In the decimal system, there are 10 possible numbers you can use ranging from zero to nine

Question 10

What is the Digital divide?

Answer 10

The growing skills gap between people with and without digital literacy skills

Question 11

What is Information Technology?

Answer 11

The use of digital technology, like computers and the internet, to store and process data into useful information

Question 12

What is Linux OS?

Answer 12

Linux is one of the largest an open source operating system used heavily in business infrastructure and in the consumer space

Question 13

What are Logic gates?

Answer 13

Allow transistors to do more complex tasks, like decide where to send electrical signals depending on logical conditions

Question 14

What is Open Source?

Answer 14

This means the developers will let other developers share, modify, and distribute their software for free

Question 15

What is a PDA (Personal Digital Assistant)?

Answer 15

Allows computing to go mobile

Question 16

What is a Punch Card?

Answer 16

A sequence of cards with holes in them to automatically perform calculations instead of manually entering them by hand

Question 17

What is a RGB model?

Answer 17

RGB or red, green, and blue model is the basic model of representing colors

Question 18

What is UTF-8?

Answer 18

The most prevalent encoding standard used today

Question 19

What is a NOT gate?

Answer 19

The NOT gate takes that input signal and outputs a signal with the opposite binary state.

Question 20

What is the AND gate?

Answer 20

The AND gate involves two input signals rather than just one. Having two input signals means there will be four possible combinations of input values. The AND rule outputs an “on” signal only when both the inputs are “on.” Otherwise, the output signal will be “off.”

Question 21

What is the OR Gate?

Answer 21

The OR gate involves two input signals. The OR rule outputs an “off” signal only when both the inputs are “off.” Otherwise, the output signal will be “on.”

Question 22

What is the XOR Gate?

Answer 22

The XOR gate also involves two input signals. The XOR rule outputs an “on” signal when only one (but not both) of the inputs are “on.” Otherwise, the output signal will be “off.”

Question 23

What is the NAND Gate?

Answer 23

The NAND gate involves two input signals. The NAND rule outputs an “off” signal only when both the inputs are “on.” Otherwise, the output signal will be “on.”

Question 24

What is the XNOR Gate?

Answer 24

Finally, consider the XNOR gate. It also involves two input signals. The XNOR rule outputs an “on” signal only when both the inputs are the same (both “On” or both “Off”). Otherwise, the output signal will be “off.”
