Answer:
the designer choose because it has many basic and advance feature and it is Synchronous digital hierarchy (SDH) and synchronous optical network (SONET)
refer to a group of fiber-optic transmission rates that can transport digital signals
with different capacities. And it feature is Almost all new fiber-transmission systems now being installed in public networks
use SDH or SONET. They are expected to dominate transmission for decades to
come, just as their predecessor PDH has dominated transmission for more than
20 years (and still does in terms of total systems installed). Bit rates in long-haul
systems are expected to rise to 40 Gbps soon after the year 2000, at the same
time as systems of 155 Mbps and below penetrate more deeply into access
networks.
2 they choose Because of these problems, the big cable networks use hybrid fiber-coax networks. The use of fiber increases the upstream bandwidth and reduces noise, making it easier for upstream data to reach its destination. But upgrading to hybrid fiber-coax is hugely expensive.
Answer:
Explanation:
Required
The expression in basic
To do this, we use () to group items, / as divide and * to combine factors
So, we have:
In basic, it is:
In basic, it is:
▪︎An onscreen camera for drawing virtual images is called "turtle" in python language.
The codes we will be using in the following algorithm are :
▪︎Turtle.left
▪︎Turtle.right
▪︎Turtle.move #upward
An algorithm to help the python turtle reach the finish line :
- Turtle.left
- Turtle.left
- Turtle.left
- Turtle.move#upward
- Turtle.move#upward
- Turtle.move#upward
- Turtle.right
- Turtle.right
- Turtle.move#upward
- Turtle.left
Considering the computer system analysis, when the multiple layers are selected, the keyboard shortcut that merges them is "<u>Ctrl+E for (Windows) or Command+E for (Macbook)."</u>
<h3>What Keyboard Shortcut?</h3>
Keyboard Shortcut combines keyboard keys to ensure software programs perform specific functions.
Keyboard Shortcuts can be made by a Computer manufacturer as part of the standard functionality of the operating system or application program or made explicitly by the user in a scripting language.
Keyboard Shortcut is different in both Windows and Macbook Operating systems.
Hence, in this case, it is concluded the correct answer is "Ctrl+E for (Window) / Command+E for (Macbook)."
