How do we call the set of components of a computer?

• Software

• Hardware

• Operating systems

• None of the answers

Which is the main component of a computer?

• CPU

• Motherboard

• RAM memory

• Power supply

How are Input/Output peripherals defined?

• Peripherals that allow the user to enter information to the device.

• Peripherals that show the user information about the device.

• Peripherals used to send and receive data.

• This type of peripheral doesn't exist.

Which are the main differences between HDD memory and SSD memory?

• HDD memory is cheaper

• SSD memory is faster

• HDD memory stores more information

• All the above answers are true.

One of the edges of an object measures 75 cm and in the drawing it measures 15 cm. We can say this object has been drawn to a scale of...

• 5:1

• 1:5

• 50:1

• 0.2

The primary views of an object are:

• The front elevation, the plan and the left or right elevation

• The front elevation, the plan and the right elevation

• The front elevation, the plan, the left elevation, the right elevation, the rear elevation and the bottom plan

• The front elevation and the plan

In cavalier perspective...

• The axes can be drawn with any angle of separation between them, as long as it is not the same.

• All three axes (X, Y, Z) are separated by the same angle: 120 degrees.

• The Y and Z axes form 90-degree angles and the Z axis forms a 120-degree angle.

• Two axes form a 90-degree angle with each other and two angles (135 degrees each) with the third axis.

In isometric perspective...

• The axes can be drawn with any angle of separation between them, as long as it is not the same.

• All three axes (X, Y, Z) are separated by the same angle: 120 degrees.

• The Y and Z axes form 90-degree angles and the Z axis forms a 120-degree angle.

• Two axes form a 90-degree angle with each other and two angles (135 degrees each) with the third axis.

Indicate which of the following statements about dimensioning is true:

• Heavy lines are used for visible outlines.

• Fine lines are used for dimension lines and auxiliary dimension lines.

• Fine dashed lines are used for hidden outlines.

• All the above answers are true.

In the figure...

• A is a dimension line end point and B is an auxiliary dimension line.

• A is an auxiliary dimension line and B is a dimension line end point.

• A is a dimension line and B is an auxiliary dimension line.

• A is an auxiliary dimension line and B is a dimension line.
