Q

What are the differences and similarities between RAM (Random Acces Memory) and ROM? (Read Only Memory)?

A

ROM is unable to be deleted or removed from the device. RAM can be deleted or removed. ROM comes with the device. RAM is introduced to the device. RAM will get deleted if not saved onto the device opon switching the device off. ROM cannot and will not be deleted even if the device is switched on or not. Both RAM and ROM permenantly or temporarily stores data that can be transmitted from the computer.

Q

What does the AND gate do? What does it look like? And what is the symbol?

A

The output will only be 1 if both values are 1. Otherwise, it will be a 0.
(this AND that both have to be 1)
- The AND gate is curvy
A ^ B is the symbol

Q

What does the OR gate do? What does it look like? And what is the symbol?

A

The output will be 1 if either input value is 1. If both are 0s, it will be a 0. But if either input is 1, the output will be 1.
(this OR that can be 1)
- The OR gate is straight arrow shape
A V B is the symbol

Q

What is the CPU?

A

The central processing unit is the main processing unit of the computer. It executes instructions that comprises of the computer program.

17
Q

What is the GPU?

A

The Graphical Processing Unit is a processor that renders images.

18
Q

What is the Motherboard?

A

It is a circuit board connected to peripherals where the CPU is installed.

19
Q

What is the Heat Sink?

A

It is a device that draws heat away from any processor that is likely to overheat.

20
Q

What is the Power Supply?

A

A device that takes in power and sends it to components that need power.

21
Q

What is the function of the Resistor?

A

Resists the flow of current in a circuit.

they kind of look like kebabs…

22
Q

What is the function of the Transistor?

A

It amplifies or switches electronic signals and power in a circuit.
(looks like a plug but with three long things sticking out of it)

23
Q

What is the function of the Capacitor?

A 
Allows AC (alternating current) to flow through them and resists DC (direct current).
(looks like a lollipop...)
24
Q

What is the function of the IC (Integrated Circuit)?

A

They integrate or combine other electrical components.

25
Q

What is the function of the Inductor?

A

It stores energy in a magnetic field when current passes through it.
(it looks like a more boring kebab…)

26
Q

What is the function of the Inductor?

A

It stores energy in a magnetic field when current passes through it.
(looks like something with wire wrapped around it.)
