The instruction pointer, also called program counter, is a special register in a processor. It holds the address of the next instruction to be executed.

The program counter (PC), commonly called the instruction pointer (IP) in Intel x86 and Itanium microprocessors, and sometimes called the instruction address register (IAR), the instruction counter, or just part of the instruction sequencer, is a processor register that indicates where a computer is in its program
EIP is a register in x86 architectures (32bit). It holds the "extended instruction pointer" for the stack. In other words, it tells the computer where to go next to execute the next command and controls the flow of a program. Research Assembly language to get a better understanding of how registers work.
In most processors, the instruction pointer is incremented after fetching an instruction, and holds the memory address of ("points to") the next instruction that would be executed. (In a processor where the incrementation precedes the fetch, instruction pointer points to the current instruction being executed.) Instructions are
25 Feb 2012 The Instruction Pointer in 8086. The code segment register holds the upper 16 bits of the starting address of the segment from which the BIU is currently fetching the instruction code byte. Now the instruction pointer comes in picture. This register is responsible for holding the 16 bit offset, of the next code
Nope, they're the same thing. A given architecture will refer to exactly one of these (in particular, x86 and x64 use IP instead of PC).
The Instruction Pointers view enables you to see specific instructions that are executed during sampling profiling. This view is not available during instrumentation profiling. For sampling profile data, the IPs view identifies the instructions in a function that was directly executing when the sample was collected. For .
