Answer:
Public Class Form1
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim foodCharge, tax, tip, totalCharge As Double
foodCharge = Val(TextBox1.Text)
tax = 0.07 * foodCharge
tip = 0.15 * 100
totalCharge = foodCharge + tax + tip
Label5.Text = tax
Label6.Text = tip
Label7.Text = totalCharge
End Sub
End Class
Explanation:
- This is implemented using Visual Basic programming language
- Firstly we declared all the variables using DIM key word
- Then the calculation for each variable is done according to the specification of the question
- On the form (See attached Image) the controls for receiving the user input is created as well as the controls for the output.
- See the attached sample run below:
Answer:
Types of Motherboard
Explanation:
Motherboards are present in Desktop, Laptop, Tablet, and Smartphone and the components and functionalities are the same. But the size of the components and the way they are accommodated on the board varies due to space availability. In desktops, most of the components are fitted inside the sockets provided on the board and it is easy to replace each of them separately, whereas in Laptops/Smartphones some components are soldered on the board, hence it is difficult to replace/upgrade.
Though different motherboards have varying capabilities, limitations, features, Physical size/shapes (form factor), they are identified/grouped/categorized mostly by their form factors. Each manufacturer has come out with its form factor to suit the design of computers. Motherboard manufactured to suit IBM and its compatible computers fit into other case sizes as well. Motherboards built using ATX form factors were used in most of the computers manufactured in 2005 including IBM and Apple.
Answer:
In terms of efficient use of memory: Best-fit is the best (it still have a free memory space of 777KB and all process is completely assigned) followed by First-fit (which have free space of 777KB but available in smaller partition) and then worst-fit (which have free space of 1152KB but a process cannot be assigned). See the detail in the explanation section.
Explanation:
We have six free memory partition: 300KB (F1), 600KB (F2), 350KB (F3), 200KB (F4), 750KB (F5) and 125KB (F6) (in order).
Using First-fit
First-fit means you assign the first available memory that can fit a process to it.
- 115KB will fit into the first partition. So, F1 will have a remaining free space of 185KB (300 - 115).
- 500KB will fit into the second partition. So, F2 will have a remaining free space of 100KB (600 - 500)
- 358KB will fit into the fifth partition. So, F5 will have a remaining free space of 392KB (750 - 358)
- 200KB will fit into the third partition. So, F3 will have a remaining free space of 150KB (350 -200)
- 375KB will fit into the remaining partition of F5. So, F5 will a remaining free space of 17KB (392 - 375)
Using Best-fit
Best-fit means you assign the best memory available that can fit a process to the process.
- 115KB will best fit into the last partition (F6). So, F6 will now have a free remaining space of 10KB (125 - 115)
- 500KB will best fit into second partition. So, F2 will now have a free remaining space of 100KB (600 - 500)
- 358KB will best fit into the fifth partition. So, F5 will now have a free remaining space of 392KB (750 - 358)
- 200KB will best fit into the fourth partition and it will occupy the entire space with no remaining space (200 - 200 = 0)
- 375KB will best fit into the remaining space of the fifth partition. So, F5 will now have a free space of 17KB (392 - 375)
Using Worst-fit
Worst-fit means that you assign the largest available memory space to a process.
- 115KB will be fitted into the fifth partition. So, F5 will now have a free remaining space of 635KB (750 - 115)
- 500KB will be fitted also into the remaining space of the fifth partition. So, F5 will now have a free remaining space of 135KB (635 - 500)
- 358KB will be fitted into the second partition. So, F2 will now have a free remaining space of 242KB (600 - 358)
- 200KB will be fitted into the third partition. So, F3 will now have a free remaining space of 150KB (350 - 200)
- 375KB will not be assigned to any available memory space because none of the available space can contain the 375KB process.
Most computer devices are connected to the computer through port
Keyboard through usb port
Printer through usb port
Hand point device through usb port
Also computer equipped with LPT port for printers and COM port for additional devices like external modems e.t.c
