Routers- Definition and Types
Routers
Routers are physical devices that join multiple wired or wireless networks together. A Router is a Layer-3 Device. A router is similar to a switch, but it can also connect different logical networks or subnets and enable traffic that is destined for the networks on the other side of the router to pass through. Routers [...]

Streams- Definition and Types
Streams
The C file system is designed to work with a wide variety of devices, including terminals, disk drives, and tape drives. Even though each device is very different, the buffered file system transforms each into a logical device called a stream. All streams behave similarly. Because streams are largely device independent, the same function that [...]

What is Graphical User Interface (GUI)
Graphical User Interface (GUI)
The term User Interface was originated in reference to an engineering environment. Prior to this programmers interacted with computers but a category of no programming users came into existence and a different form of interaction was needed for this class. This user interface was referred to as a Graphical User [...]
Role of Scanf Function in C and C++
scanf( )
scanf() is the general-purpose console input routine. It can read all the built-in data types and automatically convert numbers into the proper internal format. It is much like the reverse of printf(). The prototype for scanf() is
int scanf(const char *control_string, …);
The scanf() function returns the number of data items successfully assigned a value. If [...]
