The  difference between a database system and a database model is that Database design is saved in the place known to be database schema, which is said to also been saved in the data dictionary. Data model is said to be a group or collection of construct that is known to be used for making a database and making designs for the databases.

<h3>What is a database systems?</h3>

A database is known to be a kind of organized makeup of structured information, or data, that are said to be saved electronically in a computer system.

The hierarchical structure is known to be  used primarily to save geographic information as well as file systems.

Therefore, The  difference between a database system and a database model is that Database design is saved in the place known to be database schema, which is said to also been saved in the data dictionary. Data model is said to be a group or collection of construct that is known to be used for making a database and making designs for the databases.

Suppose there are 69 packets entering a queue at the same time. Each packet is of size 7 MiB. The link transmission rate is 1.7
svp [43]

Answer:

69.08265412 milliseconds

Explanation:

Lets first convert 7 MiB to bits

7*1024*1024*8=58720256 bits

Now convert bits to Gbits

58720256/10^{9}  =0.058720256 Gbits

Queuing Delay = Total size/transmission link rate

Queuing Delay= \frac{0.058720256}{1.7} =0.03454132706 seconds

Delay of packet number 3 = 0.03454132706*2=0.06908265412 seconds

or 0.06908265412= 69.08265412 milliseconds

jeyben [28]
<h2>Answer:</h2>

Title bar is the top most bar of a window. As obvious from the name, it has the title of the program in use. It has name of the program or more specifically the name of currently open document is written in this horizontal bar.

The option/commands present in the right most o the title bar are as follows:

  • Close
  • Maximize/Resize
  • Minimize

Close command is needed to exit the program/application. A cross icon is used as close command. Maximize/Resize command helps to expand the window to the screen pane as well as allows the user to adjust the screen of application accordingly. Two squares icon is used as a button for this command. Minimize command helps by shutting the app to the task bar so that it can be expanded/maximized later. A dash/line icon is used as a button for this command.
