Operating system: An operating system is a collection of software that manages computer hardware, software resources, and provides common services for computer programs.
Coding: Coding is the process of creating instructions in a programming language that can be interpreted by a computer or other machine.
Before the invention of the operating system, coders relied on a combination of hardware and software to create instruction sets for computers. By interfacing the hardware and software, coders could create instructions sets that allowed computers to perform certain tasks. Since computers of this era were quite primitive, these instruction sets were often written in binary code, meaning each instruction was composed of ones and zeroes.
To create these instructions sets, coders had to manually enter them into the computer using switches, knobs, punch cards, and other methods. This process, known as ‘hard-coding’, was laborious and time consuming. It was difficult to keep track of the instructions, and making changes was almost impossible. Testing the instructions was also difficult, as the coder needed to manually enter them into the computer to see if they worked.
Nonetheless, coders of this era managed to create some amazing things based on the primitive technology available to them. The results of their hard work were the foundations of what we now call ‘software’.
The invention of the operating system made programming much easier and faster. It allowed coders to write instructions sets in a higher-level language, meaning that each instruction was composed of words and symbols from the English language. This made it much easier to create instructions sets, and testing and making changes was also much faster and simpler.
The introduction of the operating system enabled coders to create more complex instructions sets, allowing computers to do more complicated tasks. This has opened up many opportunities for today’s developers, and has changed the face of computing.
History of Manual Coding
Table of Contents
Before computers were able to facilitate our daily lives with their operating systems, manual coding was the usual route people used to interact with computers. Manual coding is the process of instructing computers on what to do with hand-typed instructions. This process involved typing in machine code, a series of numbers that correspond to specific instructions, via punched cards. Computer programmers would manipulate these punched cards and then sort them in order for the computer to interpret commands.
Types of Programming Languages
Prior to modern day operating systems, there were two main types of programming languages that synthesized data and instructions: low-level languages and high-level languages. Low-level languages are programming languages that directly communicate with the computer and command it to manipulate individual components. Low-level languages are not efficient as they require more effort and time to program. High-level languages, on the other hand, are programming languages that are easier to use and are able to be more versatile with their commands to the computer.
The Punched Card
The punched card was a piece of perforated paper that was used to collect and store data. This was the main way we input computer instructions and other data before the invention of the modern day operating system. The punched card acted as a storage unit for the computer and was used for both input and output. The programmer would create programs by punching holes in a card that represented instructions, which can then be sorted and read by a computer.
- Low-level languages directly communicate with the computer.
- High-level languages are easier to use and are more versatile.
- The punched card was used to collect and store data.
Advantages and Disadvantages of Coding Without an Operating System
Pre-Operating System Coding Methods
Before the modern operating systems that are used on computers and other electronic devices today, coders had to create their own methods for writing and running programs. This was often done through the use of assembly language, which required tedious and complex instructions that had to be input into a machine language code. Additionally, coders had to use a variety of physical components such as switches and relays in order to control the flow of instructions in their program. This was known as hardwiring. It was a laborious task just to write and debug code, not to mention its seemingly endless opportunities for error.
Advantages of Coding Without Operating Systems
Despite the complex nature of pre-operating system coding methods, there were some advantages to coding without them. Since everything was hardwired, coders had full control and insight into how every instruction was handled. This allowed them to make sure their code was running as instructed and to find and fix any errors quickly. Additionally, because assembly language was so efficient at translating instructions into machine language, programs written using pre-operating system coding methods tended to be faster and more efficient than those written on operating systems.
Disadvantages of Coding Without Operating Systems
The complexity of pre-operating system coding also led to a number of disadvantages. Obviously, the difficulty of writing and keeping track of all the instructions made coding a difficult and time consuming process. Additionally, hardwiring was limited in its functionality and could only handle a relatively small amount of instructions. This meant that programs were often limited in their scope and functionality and this wasn’t always suitable for larger projects. Finally, the lack of a standardized language meant that coders often had to use different codes depending on the hardware they were using. This made it difficult to collaborate or even share code with other coders.
Impact of Operating Systems on Modern Coding
Introduction to Coding Pre-Operating Systems
Computer programming, or coding, is an important aspect of modern technology, and has been around for many years. Before the invention of operating systems, coding was still possible, and a lot of the same principles still applied. While much of the code was much more complex than today, coding existed in a pre-operating system world, and that code was still relevant and accomplished a lot of similar duties.
Techniques Involved with Pre-Operating System Coding
Without the aid of an operating system, coding was done mainly through the use of assembly languages. If a program was too complex, the individual pieces of code need to be written in assembly language and then physically wired together. This was very labor intensive, but many programs could still be created in this way, even if complex calculations and other tasks were involved.
Along with assembly languages, pre-operating systems typically used written codes to assist in programming. Known as mnemonics, phrases like “load and store” could be used to replace long lines of assembly language. Many of these codes were the same or very similar to codes used in modern programming techniques, and helped to speed up the process even when no operating system was available.
Limitations of Pre-Operating System Coding
The biggest limitation of pre-operating systems coding was the time and effort it took to create a program. Without the help of an operating system, programs had to be crafted by hand and tested on physical computers, usually with limited memory ordisk space. This meant that programs could only be as large as the physical memory allowed, and debugging and testing was a long and painstaking process.
Furthermore, because assembly language was used heavily, codes had to be crafted to take full advantage of the individual hardware. Without any type of abstraction or translation, programs written for one system would not run on a different platform, and each hardware platform would require code specifically designed for it.
Modern operating systems have allowed code to be much more abstract, so programs can run on multiple platforms with a minimal amount of customization. This was not possible with pre-operating systems and also adds to the difficulty associated with coding.
