Computer Systems

These frameworks are part of a complex setup of hardware, software, and additional equipment. It is designed to work together to handle data processing. Just like a body and soul, hardware and software are inseparable. In this case, hardware refers to the physical components, and software refers to the program that operates the platform. However, these two will not work without user interaction to perform the tasks. 

The way computer systems work begins with input, where the user provides the command. Then, it goes through the CPU, where the processes are happening, using instructions from software. After that, the information will be stored for later use. Anytime someone asks for the same task again, the result can be shown. 

What are the 4 computer systems?

Based on their size, there are four types of computer systems: micro, mini, mainframe, and supercomputer. Each of them has different application and performance requirements. It depends on the complexity of the task and the required performance. It means they have different kinds of hardware and software to make them work properly.

These configurations of computer systems come in different forms and are categorised based on various factors. You can find differences in data processing speed, the type of data they handle, and their physical size. Each of them has a different purpose. Further explanation below will improve your knowledge about all these types, such as:

Microcomputer

A microcomputer is the smallest form of computer system and relatively the cheapest one because it uses a microprocessor as its central processing unit (CPU). Thus, it becomes one of the types that most people use and are familiar with. You might find this type in the form of desktops, laptops, or even tablets. In this regard, the devices typically consist of several components, such as:

• Microprocessor (CPU): The Central Processing Unit (CPU) is the critical component of a computer. It acts as the brain to operate the program.
• Memory (RAM): Random Access Memory (RAM) is the short-term memory of a computer. It aims to access and store data and information for the time being.
• Storage (hard drive or SSD): Storage is a place where a device can put information for later use. This storage can be in a Hard Disk Drive (HDD) or a Solid-State Drive (SSD). SSDs use flash memory, which makes them work faster and more reliably. HDDs use magnetic disks that are more affordable and offer higher storage capacity. 
• Input/output devices (keyboard, mouse, and display): They are the hardware components that interact with the computer systems. Input devices include keyboards and mice to send the data to the system. The output device, on the other hand, is the result of that interaction through displays.

Minicomputer

In terms of power, size, and cost, this type lies between a mainframe and a microcomputer. People developed it in the 1960s and gained its popularity in the 1970s and 1980s. Industries, laboratories, and small to medium-sized businesses were using this tool at that time. This is because this device can handle multiple tasks and support multiple users at the same time. Thus, it is suitable for managing business processes, databases, and scientific applications.

As time went on, the mini type started to lose its popularity when computer systems like micro versions and servers became more powerful and affordable. The term “minicomputer” started to fade away. Today, people know this type as a mid-range type or a workstation. However, this type of change enables more companies to access computing power cheaply.

Mainframe computer

It is one of the types of computer systems that large organisations, like banks, the government, airlines, and insurance companies, use for their work. The setup is designed to handle vast amounts of data and support up to thousands of users at the same time. It can perform critical and complex tasks that require high speed, reliability, and security.

Until now, nothing can beat the effectiveness of this kind. This is because the mainframe version can run nonstop without failure, unlike other computer systems. This type is the most reliable version when it comes to massive data processing and doing multiple transactions at the same time. Behind these benefits, there are key characteristics that are associated with it, such as:

1. High processing power: Can handle millions of tasks per second.
2. Reliable: Designed to operate nonstop for years with minimal failures.
3. Huge storage capacity: Able to store and manage one million gigabytes of data.
4. Advanced security: Has strong security protection to handle sensitive and critical data.

Supercomputer

Compared to other computer systems, the super version is the most powerful in terms of processing speed and computational capability. You can find this type in fields that require massive data processing, such as climate modelling, scientific research, space exploration, and nuclear simulations. This is because they can perform extremely complex and large-scale calculations at high speeds. 

This version aims to solve several highly demanding problems very quickly. However, it can not serve multiple users at the same time. That is why you often find it in research institutions, government agencies, and universities. To further understand it, below are the key traits of this setup:

• Extreme processing power: Can perform trillions of tasks per second.
• Parallel processing: It uses thousands of processors at the same time to solve problems.
• High cost and complexity: This setup is hard to build and maintain. It needs advanced cooling systems and infrastructure.
