Assembly Language
From HandWiki
Assembly Language is a method of abstracting machine code instructions for a computer into commands recognizable by a human. Instead of dealing directly with bit sequences, programmers write programs in assembly by generating blocks of code using a small set of keywords (which are mapped to machine instructions by an assembler).
An example Hello World program written in pseudo-assembly is listed below. Original source: Assembly Language for the IBM-PC.
.data hello_message db 'Hello, World!',0dh,0ah,'$'
.code main proc
mov ax,@data mov ds,ax
mov ah,9 mov dx,offset hello_message int 21h
mov ax,4C00h int 21h
main endp end main
Assembly programs are much easier to understand than their corresponding machine code instruction streams, but they are much more difficult to comprehend than, say, the PHP Hello World program.
