6 Advantages and Disadvantages of Mainframe Computer | Drawbacks & Benefits of Mainframe Computer

Mainframe Computer: What is it?

A mainframe computer is a highly performant system made up of several processors. In comparison to a standard computer, it performs better, but not as well as a super computer.

Who uses Mainframe Computer?

Large organizations typically pick mainframe computers when they require robust devices with significant processing power. Mainframe computers are also used by other industries, like banks and corporations, to conduct safe transactions. There are various kinds of mainframe computers available depending on the needs. They all differ based on their unique attributes. A few mainframe computer examples are ASCC, ENIAC, UNIVAC, and EDVAC.


Mainframe computers aren't perfect, even though they usually help with more complex tasks. There are a number of benefits and drawbacks, depending on the environment they are utilized in and other variables. You can use these advantages and disadvantages to assess whether it will meet the demands of the user.

You will learn about the 6 Advantages and Disadvantages of Mainframe Computer | Drawbacks & Benefits of Mainframe Computer. You will learn about the pros and cons of mainframe computer use from this page.

Now let's get started, 

 

Advantages of Mainframe Computer

1. Security

Mainframe computers are developed with security as their first priority since they are intended for use by organizations that require highly secure transactions. Excellent security is built into every mainframe computer to ensure that the data is well safeguarded. 

 

Mainframe computers are especially useful for large-scale businesses like banks and insurance companies who need to protect sensitive data.


2. Reliability

Another characteristic of a mainframe computer is reliability. In most cases, when a system fails, it will attempt to restart itself. If not, the administration will be informed right away. After that, the administrator will be able to replace the damaged hard drive.


3. Durability

The main characteristic of mainframe computers is their extraordinary longevity. These computers last more than ten years on average. Up until that point, mainframe computers typically don't have any issues. 

 

The users can choose to upgrade the machine or replace it once its typical lifespan has been achieved. 

 

4. Scalability

Hardware and software scalability of mainframe systems is very high. They can readily complete jobs with a high degree of complexity because to their scalability. 

 

For instance, a mainframe computer's overall processing performance is increased when multiple processors are attached to it.


5. Virtualization

The virtualization method is what mainframe computers utilize to get around memory restriction issues. 

 

The system as a whole is split up into sections that manage numerous virtual computers during this procedure. The combined computing power of all these machines is boosted.


6. Compatibility

A variety of devices and applications are supported by the operating system that comes with mainframe computers. The majority of the software will function on the mainframe computer regardless of age. 

 

The system is capable of running out-of-date programs even after it has been upgraded. Additionally, the number of operating systems that can run on mainframe computers is not limited to just one. 

 

It is possible to configure multiple operating systems to run simultaneously, which could improve system performance overall. 

 

Disadvantages of Mainframe Computer

 
1. Installation

Because of their hardware components, mainframe computers are more complicated to install than standard computers. Their physical components are far greater than those of a standard PC. 

 

Furthermore, an independent operating system for mainframe computers is needed, which is distinct from an ordinary O/S. The user cannot utilize this machine until this operating system is installed.


2. Cost

A mainframe computer is far more expensive to start with than a standard computer. The mainframe computer is costly due to its hardware and software. 

 

Actually, a mainframe system is beyond the budget of the average user. Because of their sophisticated functionality, mainframe computers are only preferred by large organizations.


3. Physical Size

In addition to being more expensive, mainframe computers usually require more room. This was the primary issue at the time mainframe computers were invented. Mainframe computers generally have a refrigerator-like appearance. 

 

Nevertheless, compared to past times, mainframe computers are now substantially smaller.


4. Maintenance

Mainframe computer maintenance is not a task that can be completed by regular staff members. Handling tasks, such as system debugging, is necessary. Only highly skilled employees will be able to control the system.


5. Resource Requirement

Generally speaking, a mainframe computer has a few sophisticated functions. Consequently, compared to a standard system, it needs more resources. Increased resource usage basically indicates that the system's overall costs will rise.


6. Environmental Restrictions

The environment in which mainframe computers should be installed has restrictions as well. It is not appropriate for the surroundings to be really hot. If not, it can abruptly shut down the system. This needs to be avoided by using a specific cooling system.
