Manual coding of 8086 is difficult hence we use a assembler or a compiler. Note that the microprocessor should be able to interpret your discussions via the program. Suppose if the instruction corresponds to word(16 bits), we use assembler directive WORD PTR, but when assembler is contacting the processor it sets a bit called 'w' indicating its a byte operation.
There are some instructions in the assembly language program which are not a part of processor instruction set. These instructions are instructions to the assembler, linker and loader. These are referred to as pseudo-operations or as assembler directives.
A statement in an assembly-language program that gives instructions to the assembler and does not generate machine language.
The three types of assembly language are: 1. Imperative: indicates an action to be performed. 2. Declaration 3. Assembler Directives
Assembly langue is translated into machine language by an assembler.
what is the difference between an assembler and the translator
An Assembler converts an assembly language source code into machine-specific code.
Micro assembler is a assembler which is a sub part of assembler. It is also translate a low level language to machine level language.Sri himadri sekhar maitilecturerdepartment of computer scienceraja n.l.

Assembler directives are also known as pseudocode.It is instruction to assembler regarding the program to be assembled. For example ORG 4000 is an assembler directive which tells the assembler that program is stored from location 4000.
The simple answer is that the resulting program is not portable.
For completing all the tasks, an assembler needs some hints from the programmer, i.e. the required storage for a particular constant or a variable, logical names of the segments, types of the different routines and modules, end of file, etc. These types of hints are given to the assembler using some predefined alphabetical strings called assembler directives, which help the assembler to correctly understand the assembly language programs to prepare the codes.

the question is not clear. the chip with which 8086 has to be interfaced should be mentioned. for example, interfacing 8086 and 8087( NDP) or 8086 and 8255( PPI) or 8086 and 8259( PIC) or 8086 and 8089( IOP) But to make the answer complete I would like to mention 2 references 1.Douglas Hall, "Multiprocessors and Interfacing , Programming and Hardware", Tata Mcgraw-Hill.1999, second edition. 2.John Uffenback, "8086/88 Interfacing, Programming and Design", 1987, PHI.
A macro processor is software. Usually a part of a compiler or an assembler, used to program a computer.A microprocessor is hardware, one type of computer implementation.Very different things.The macro processor was first created in the 1950s and was used on large vacuum tube mainframe computers (long before the first microprocessor).
No. They have a different instruction set. However, the processors are sufficiently similar that an 8086 assembler could assemble an 8085 program, given appropriate constants and macros. Some things, however, such as RIM, SIM, RST, etc. do not have equivalents in the 8086.
