What Are the Characteristics and Applications of Computers? – BBA First Semester LU Notes
Characteristics of Computers
-
Speed:
- Computers operate at incredibly high speeds, completing calculations in mere seconds that would take humans hours. They can execute millions of instructions per second, measured in microseconds (10^-6 seconds) or nanoseconds (10^-9 seconds).
-
Accuracy:
- Computers have a high degree of accuracy, consistently performing calculations without errors. Their accuracy level is determined by their design, with mistakes typically arising from human input or incorrect data.
-
Diligence:
- Unlike humans, computers do not tire or lose concentration. They can work continuously for long periods, performing millions of calculations with the same accuracy and efficiency.
-
Versatility:
- Computers can perform a wide range of tasks, from creating payroll slips to managing inventory or generating bills. This adaptability allows them to handle diverse types of work seamlessly.
-
Power of Remembering:
- Computers have the capability to store vast amounts of information, which can be retrieved whenever needed. The amount of data they can hold depends on the user’s requirements.
-
No IQ:
- Computers lack intelligence and cannot perform tasks independently. They execute instructions provided by users at high speeds and accuracy, but they do not make decisions on their own.
-
No Feelings:
- Computers do not possess emotions, feelings, or human-like experiences. They can work for extended periods without fatigue and treat all tasks equally without bias.
-
Storage:
- Computers have built-in memory to store data and can also utilize secondary storage devices, such as floppy disks, for additional data storage that can be transported to other computers.
