As someone who worked in engineering and construction, I've learned about the fascinating difference between reinforced concrete and prestressed concrete. Let me share some of my knowledge with you all.
What is the different between RCC and PCC?
Concrete in the compression side of the neutral side of the axis alone is sufficient in RCC beams. It is useless to place concrete on the neutral axis' tension side. However, in a prestressed concrete beam, the entire portion is functional.
In general, reinforced concrete beams weigh a lot. They usually require shear reinforcements in addition to longitudinal reinforcement for flexure. The beams made of prestressed concrete weigh less. A significant portion of the shear is resisted by the pre-compression and the curved tendons.
It is not necessary to use high-strength concrete in reinforced concrete beams. However, high-strength steel and concrete are required for prestressed concrete beams. For the anchorages to withstand significant forces, highly durable concrete is required. To transfer a significant amount of prestressing force, high-strength steel is necessary.
There is no means to test the steel and the concrete in reinforced concrete beams. Steel and concrete can be tested in prestressed concrete beams while they are being prestressed.
These are a few points of difference between prestressed and reinforced concrete.
The structures that surround us are shaped by both the novel strength of prestressed concrete and the classic dependability of RCC.
Hope this helps you to understand the difference between reinforced concrete and prestressed concrete.

RCC or Reinforced cement concrete, is a composite material made of cement, gravel, and water. It is reinforced with the help of steel or iron bars. The bars are embedded in the concrete before it sets. On the other hand, PCC, or prestressed concrete, is a mechanism that aims to provide precompression in the concrete beam by means of tensioned wires, rods, cables, and more. Once you understand the meaning of RCC and PCC, you can figure out the difference between RCC and PCC as well. The above answer already speaks of some, so let me add a few more differences to the list.

What is the RCC and PSC difference?
The main difference between PSC and RCC is that the former is way lighter than the latter. Other differences between the prestressed concrete vs reinforced concrete are-
| RCC | PSC |
The concrete in the compression side of the neutral side of the axis of RCC beam is only effective and the concrete in the tension side of the neutral axis is ineffective |
The entire section of the prestressed concrete is effective |
RCC beams are heavy |
PSC beams are usually lighter |
High strength concrete is not needed |
In PSC beams, high strength concrete and high strength steel are necessary |
RCC beams are desirable where the weight is more desired than strength |
PSC beams are suitable for heavy weight and durability |
There is no way of testing RCC beams |
PSC beams can be tested |
I hope these differences also answers what are the advantages of PSC over RCC. Seek an expert’s advice to know which concrete will be suitable for which structure.
This is all I can say to help you know the difference between RCC and PCC.

What is the difference between prestressed concrete and reinforced concrete?
Difference between RCC and prestressed concrete:| RCC Concrete | Prestressed Concrete |
| Fatigue limit is low. | The fatigue limit is high. |
| It gets deformed more than PSC. | It deforms less than RCC. |
| The product price to manufacture RCC concrete is low. | The product price to manufacture prestressed concrete is high. |
| Deformed bars and mild steels are inserted in RCC concrete. | High-quality tendons are used. |
| Internal stress is not introduced in RCC. | In prestressed concrete internal stress is introduced prior to loading. |
| Tensile cracks can be seen. | Tensile cracks are not seen. |
| RCC concrete doesn't need quality control. | Good quality control and skilled labour are required. |
| Shear reinforcement is required. | Tendons help to resist the shear reinforcement. |
| High strength is not needed in RCC. | High strength is required in prestressed concrete. |
| Steels cannot be tested in RCC. | Steels can be tested in prestressed concrete by placing them inside. |
| Needed for construction of the building. | Needed for construction of railways, sleepers, bridges, and gravity dams. |
