TCP
v No loss
v Retransmits all lost messages
v Potentially large latency
UDP
v Potentially unbounded loss
v Does no retransmission
v Minimal latency
à Neither of them is what you want for streaming applications
Solution
v UDP with
o Congestion control
o Reliability control (error protection)
v How?
o Keep UDP throughput ~ to TCP
o By using FEP (forward error protection) and ARQ (automatic repeat request)
v Advantage
o Can recover from loss in time independent of link RTT
o Unequal protection: more important data is better protected
o Pre-roll buffers to cope with increased delay for streaming applications
v Disadvantage
o Pay overhead
o Increased delay
o Poor quality for real-time applications

Why classb is preferred over class c modulation?
That depends on the use. Each has advantages in different applications. Without more specifics on your application I cannot comment usefully.
Why is PC preferred over laptop?
if you mean why is a desktop preferred over a laptop. then i would answer that they aren't and that laptops are preferred because of their convenience
Why is denatured alcohol preferred over regular ethanol in industrial applications?
Denatured alcohol is preferred over regular ethanol in industrial applications because it contains additives that make it unfit for human consumption, which allows it to be sold without the high taxes associated with beverage alcohol. This makes denatured alcohol more cost-effective for industrial use while still providing the benefits of ethanol as a solvent or fuel.
Why is sodium preferred over potassium in industrial applications?
The question isn't very specific (preferred for what?!), but sodium metal is less reactive than potassium. It is also slightly more abundant than potassium on Earth.
Why is silicon preferred over germanium?
Silicon is generally preferred over germanium for electronic applications because it has a higher bandgap energy, allowing for the creation of more efficient and faster electronic devices. Silicon is also more readily available and easier to work with in terms of manufacturing processes compared to germanium. Additionally, silicon has better thermal stability and higher breakdown voltage, making it more reliable for long-term applications.
Why interval estimates are preferred over point estimates?
Interval estimates are generally to be preferred over point estimate
What is the device that allows you to talk to people over a telephone line?
a telephone
Why are artificial magnets are preferred over natural magnets is most application?
Artificial magnets are preferred over natural magnets in most applications due to their superior magnetic properties, such as stronger magnetic fields and greater consistency in performance. They can be engineered to achieve specific characteristics, including different shapes, sizes, and strengths, making them versatile for various uses. Additionally, artificial magnets are less susceptible to demagnetization and environmental factors compared to natural magnets, ensuring reliability and longevity in applications.
What is better perspex or glass?
Perspex, also known as acrylic, is generally preferred over glass for its lightweight nature, durability, and impact resistance. It is also less prone to shattering, making it safer in certain applications. However, glass may be preferred for its clarity and heat resistance, depending on the specific use case.
