ALU

In computing, an arithmetic logic unit (ALU) is a digital circuit that carries out arithmetic and logical operations. The ALU is a basic building block of the central processing unit (CPU) of a computer, and yet the simplest microprocessors include one for purposes like maintaining timers. The processors found inside current CPUs and graphics processing units (GPUs) have inside them very influential and very complex ALUs; a single part may have numerous ALUs.

Pointer declaration

A pointer is a variable that has the memory location of an additional variable. The syntax is as shown below. You start by specifying the kind of data stored in the location recognized by the pointer. The asterisk tells the compiler that you are creating a pointer variable. Lastly you give the name of the variable.

Data type * variable name

Example:

int *ptr;
float *string;

What is Internetwork?

Two or more networks or network segments associated using devices that operate at layer 3 (the 'network' layer) of the OSI Basic Reference Model, like a router. Any interconnection between or between public, commercial, private, industrial, or governmental networks may as well be defined as an internetwork.

In recent practice, the interconnected networks make use of the Internet Protocol. There are at least three variants of internetwork, dependent on who administers and who participates in them:

* Intranet

* Extranet

* Internet

Intranets and extranets might or might not have connections to the Internet. If attached to the Internet, the intranet or extranet is generally protected from being accessed from the Internet without correct authorization. The Internet is not considered to be a part of the intranet or extranet, even though it can serve as a portal for access to portions of an extranet.
