A. because everyone basically has seen it..
Answer:
A Port Replicators.
Explanation:
Port replicators are devices or extension. They are plugged into the laptop's usb port to provide extra ports to connect other external devices needed by the laptop.
Docking stations does the same thing, but the laptop is plugged into the docking station holding the needed devices, and meant for that laptop brand.
Answer:
Name.
Explanation:
The constructor in the class must have the same name as the class.Constructors are used to initialize the object when created.There are basically three types of constructors which are as following:-
- Default Constructor.
- Parameterized Constructor.
- Copy Constructor.
Default Constructor:-This constructor is already present in the class when the class is defined.It does not have any arguments.
Parameterized Constructor:-As the name suggests this constructor have parameters that are used to initialize the object.
Copy Constructor:-This constructor is called whenever an object is copying the values of other object.For example:-
There is already an object present with name obj1.
class obj2=obj1;
Answer:
A pneumatic system is a system that uses compressed air to transmit and control energy. Pneumatic systems are used extensively in various industries. Most pneumatic systems rely on a constant supply of compressed air to make them work. This is provided by an air compressor.
A hydraulic system is a drive technology where a fluid is used to move the energy from e.g. an electric motor to an actuator, such as a hydraulic cylinder. The fluid is theoretically uncompressible and the fluid path can be flexible in the same way as an electric cable.
Explanation:
<h3>Examples of pneumatic systems and components
</h3><h3>Air brakes on buses and trucks.
</h3><h3>Air brakes on trains.
</h3><h3>Air compressors.
</h3><h3>Air engines for pneumatically powered vehicles.
</h3><h3>Barostat systems used in Neurogastroenterology and for researching electricity.
</h3><h3>Cable jetting, a way to install cables in ducts.
</h3><h3>Dental drill.</h3>
<h3>Hydraulic systems use the pump to push hydraulic fluid through the system to create fluid power. The fluid passes through the valves and flows to the cylinder where the hydraulic energy converts back into mechanical energy. The valves help to direct the flow of the liquid and relieve pressure when needed.</h3>
Answer: Internet layer in TCP/IP stack is used for the transmitting and exchanging of information or message between the source and destination in computer systems.The main functions performed by this layer are as follows:-
- It transfers the message to the network interface layer
- The correct information route and destination is established
- Prefers intelligent routing technique by choosing the shortest route among all paths
- If any error case of transmission arises then another alternate path for datagram transmission is used.
