Low level

A low-level programming language refers to machine code or what is called assembly language. This is the one closer to the hardware for small abstraction present between the latter and the machine language.

Low-level PL converts easily into machine code, something that a computer can directly process as is, so there is no need for a compiler or interpreter . The code runs on the processor itself ergo programs written with this run fast and do not consume that much in memory.

PROG LANGUAGES

PC Speak: An Abney and Associates Internet and Technology Research Lab summarizes the following programming languages.  Programming languages are artificial languages used in giving instructions to a machine (particularly a computer) that it could understand. They are employed in creating programs or software and have control on the performance, output and activities of a machine.

PLs are characterized by their syntax (form) and the meaning of its code (semantics). They are quite different from human languages as PLs are finite, exact and can be fully understood

Conversion

We provide details here on how to easily (for those who want long-winded procedures, we also have the complex way) convert one numeral system to another.

Hexadecimal

Hex or hexadecimal is the base-16 numeral system that uses 16 different symbols ranging from the digits 0 to 9 and the letters A to F (representing values from 10-15). Hexadecimal is a positional number system in Computer Science and Mathematics.

Each hex digit is equal to 4 bits (binary digits) and or what is called 1 nibble (half an octet). Hex system is […]

Octal

Base-8 numeral system or octal uses digits from 0 to 7 and can be achieved from grouping consecutive binary digits into groups of 3.

Octal is sometimes used instead of hex as it does not require other symbols as digits, as opposed to the hex system that requires 6 letters.

Binary

A base-2 positional notation is a numeral system which only uses the digits 0 and 1. This is very well-known for machines understood it for its simple implementation. In fact, it is not only employed on computers but also on associated machines such as logic gates and facilitate internal communications among components of a machine.

Numeric value of a binary number depends on only two states which are usually designated as “on” and “off” (or in some cases, “yes” or “no”). Any number can be converted into binary numerals (bits).
