In this era where we use computers every day to do our job or other tasks, we are no longer strangers with errors or software bugs. Surely, we experienced almost every common software bug or error at some point in our technology-dependent lifestyle. It is indeed a bother whenever those occur. We might lose our focus or even the energy to continue to work.
Techopedia defines software bugs as “a problem causing a program to crash or produce invalid output. The problem is caused by insufficient or erroneous logic. A bug can be an error, mistake, defect or fault, which may cause failure or deviation from expected results. Most bugs are due to human errors in source code or its design. A program is said to be buggy when it contains a large number of bugs, which affect program functionality and cause incorrect results.”
Having knowledge about them won’t harm, right? Here are they;
1. Error Handling Error
Computers also have their fair share of time not knowing things just like humans. If the software errored but the computer can’t determine what type of error, it is called error handling error. Usually, computers will settle on a message “something bad happens.”
Crash is probably the most common software error. It happens when a software application suddenly fails because of the failure of handling exceptions. It could also happen to the operating system of a hardware device like a hard disk or to a program. It forces itself to shut down, making it dysfunctional for a moment.
3. Functional Error
Software have their own specific function and if it fails to deliver in accordance with what it should do, then it is having a functional error. For example, the Escape Button is meant to save all the changes after exit, but it didn’t, then it is an example of a functional error.
4. Missing Command Error
Every activity has a command and options to do so. If it’s obvious that a particular command must appear, but it didn’t then it has a missing command error. For example; a missing check out button after adding the products to the cart in an online shop.
5. Hardware Usage Error
Hardware Usage Error happens when the software is used in the wrong hardware device. Compatibility is the issue, especially if the software is updated and the hardware can no longer support the version of the software. Otherwise, it won’t function.
6. Acknowledgment Message Error
Most activities in the system must have a response from the computer to acknowledge a certain command that has been done. If it fails to do so or deliver the right feedback, this is an acknowledgment message error.
7. Calculation Error
Mathematics and logic are some of the foundations of computers. It also includes calculations that are being used so everything will run smoothly. If there’s an error, we’ll never know how much is at stake. One famous example was what happened on Mars in 1999. Mars Climate Orbiter burned up in the Martian atmosphere because of the failure of NASA engineers to convert units from English to Metric.
8. Syntactic Error
Remember the time when there’s a misspelled word or grammatically incorrect sentences on your screen? You think that it is quite strange knowing the infallibility of computers when it comes to language. But these are syntactic errors and they are very evident while testing software GUI. These are misspelled words or grammatically incorrect sentences.
9. Control Flow Error
Every activity on the computer follows a control flow. If it fails to proceed in the right flow, it is safe to assume that it is a control flow error. Example: After filling up the payment method of a product, it didn’t proceed to the confirmation page.
Just like any problem, software errors or bugs must be solved immediately. Even though it is almost normal to happen, these problems must be treated with proper attention. Remember that it could also deal a lot of damage as it eats a lot of time when on the process of treatment. In business, we always prioritize utilizing time in its most efficient use, so treat it right.
