Answer:

The Transport Layer

Explanation:

The <em>Open Systems Interconnection (OSI)</em> is a series of networking procedures or protocols contained in layers, precisely seven 7 layers. It ensures that standard protocols are used by different systems to communicate. The OSI model comprises of seven abstract layers, they are:

7. Application Layer

6. Presentation Layer

5. Session Layer

4. Transport Layer

3. Network Layer

2. Datalink Layer

1. Physical Layer

Every layer uniquely carries out a specific function and communicates with the layers below and above it. When a user receives data, the flow on the OSI model is from Layer 1 to Layer 7, but if the user is transmitting data, the flow is from Layer 7 to Layer 1.

<em>The transport layer</em> ensures that end-to-end communication is carried out efficiently. It is also responsible for error control and flow control. During data transmission, data is collected from the session layer and broken down into segments, these segments are now sent to the Network layer. While when data is received, the transportation layer reassembles the broken down segments into data and sends it to the session layer.

stiks02 [169]

Answer: True

Explanation: For loop is used in the C++ programming is defined as the statement that defines about the flow control .This loop works under some condition that is considered.

For loop is evaluated to execute for one time if the statement condition is true but there are also chances of no execution at all because of the incorrect condition. So, for loop might not run even once in that condition.Thus , the statement given is true.
