• Time Period: The Forties and Nineteen Fifties marked the start of digital computer systems. They had been the brand new fashion, replacing vintage mechanical ones.
• Size and Cost: These early computer systems have been large! And they got here with a big charge tag too.
• Basic Functions: Despite their size and price, they might only do easy obligations.
• No Operating System: Imagine a laptop without an operating machine! That’s how they have been. They simply did duties separately.
• Serial Processing: This means they end one challenge before beginning the subsequent. No multitasking right here!

Limitations of First Generatio

• Wasted Power: The fundamental computer mind, the CPU, frequently simply sat there doing not anything. It waited loads, especially throughout responsibilities like analyzing information, which wasted its power.
• One Task at a Time: These systems have been like someone who can’t multitask. They could handle one process at a time, making things sluggish.
• Long Wait Times: Imagine giving someone a process and waiting a while to look at the result. That’s how those structures have been. You’d provide them with an undertaking, and it took forever to get the final results.

Second Generation (Batch System)

Due to the inefficiencies of serial processing, the need for a greater optimized approach have become obtrusive. This led to the improvement of a batch-processing machine. This generation (1950-60) is referred to as the second era of running systems. 

In a batch system, comparable duties (or jobs) are grouped into batches and then processed sequentially with none person interaction.

The aim changed into to automate the processing of jobs and limit the setup time.

A scripting language, Job Control Language (JCL), was brought to control these batches.

It lets operators specify the collection of jobs to be completed.
