Assembly language
In the 1940s, the first recognizably modern electrically powered
computers were created. The limited speed and memory capacity forced
programmers to write hand-tuned assembly language programs. It was eventually realized that
programming in assembly language required a great deal of intellectual effort.
What Is an Assembly Language?
An assembly language is a type of low-level
programming language that is intended to communicate directly with a computer's
hardware. Unlike machine language, which consists of binary and hexadecimal
characters, assembly languages are designed to be readable by humans.
How Assembly Languages Work
?
Fundamentally,
the most basic instructions executed by a computer are binary codes, consisting of ones and zeros.
Those codes are directly translated into the “on” and “off” states of the
electricity moving through the computer’s physical circuits. In essence, these
simple codes form the basis of “machine language,” the most fundamental variety
of programming language.
Of course, no human would be able
to construct modern software programs by explicitly programming ones and zeros.
Instead, human programmers must rely on various layers of abstraction that can
allow themselves to articulate their commands in a format that is more
intuitive to humans.
High-level languages,” which utilize intuitive syntax
such as whole English words and sentences, as well as logical operators such as
“and,” “or,” and “else” that are familiar to everyday usage.
What are
theAdvantages and Disadvantages of Assembly Language ?
Pros
- Execution may be more simple
compared to other languages
- Execution is usually faster
compared to other languages
- Allows for direct control over
hardware
- Code may remain smaller compared
to other languages
Cons
- Programming may be more
challenging to pick up compared to high-level languages
- Syntax of assembly languages is
difficult
- Not portable between machine.
