Computers vs Humans
Different factors that allow for functioning of computers and humans must be taken into consideration when comparing the two. Computers designed based on the human brain as well as its functioning. Even so, there are still many differences between the two, likewise to similar features. Differences and similarities are also evident in input, output and processing devices including storage as well as systems of information retrieval from their storage (Whitworth &Ryu 1).
Resemblances between human processing and computer processors are mainly based on the computer processor (CPU) and the brain. Processing within the computer also needs electricity and it is available in the brain. The CPU is responsible for processing while human brain basically needs transistors services, which are available in computers and in humans (Whitworth & Ryu 3).
However, the difference between human processing and the computer is mainly the speed of processing, initiation, self-processing and centralization of processing. Computer processing is much faster compared to human processing because it takes more time for recollection. Even so, while computers base their processing in the central processing unit, human beings have many neurons.
Multiple neurons makes it very difficult for human beings to ‘’hang’’ as it is the case with computers (whitworth & Ryu 3). Additionally, the human brain is always in a better position to self-process and it can easily change or monitor itself besides initiating the though process on its own. On the other hand, the computer needs processing input and it can change or monitor just like the way humans do especially in the event where possibility exists, it is often on a minimal level.
Over the years, computer input devices have also increased in variety from mouse and traditional keyboard to touch capabilities and joysticks. For recognition and voice input, the microphone is used including scanners and biometrics because they form part of computer input devices. They are input devices that help humans to communicate efficiently with computers.
The sense of taste, touch, hearing, sight and smell are input devices for humans. Through these devices, information is passed into the brain for reaction and processing. The human sense of hearing as well as computer voice demand is also the same because they utilize sound signals to perform commands/functions. Humans and computers by touch are therefore capable of carrying out different functions including hugging, hitting as a sign of emotion and to nudge. Computers with touch capability get commands from touch interfaces (Whitworth & Ryu 4).
However, computers lack sense of sight unlike human beings who possess. For computers that have the function, they are incapacitated when it comes to expression, light and angle. Therefore, face recognition software in computers may not necessarily recognize a person if she or he wears glasses, a hat or a moustache (Ahnk et al. 2).
Human output devices on the other hand include voice, action and facial expression. Facial expression however includes the use of computer output devices including screen display, sound and printouts when connected to other devices such as a printer. Therefore, the only similarity between the computer and human is output sound. The rest are completely different.
Hard disk and flash memory also form the bulk of computer storage. Optical disks can be utilized to store computer information. Absence of these devices means that a computer system cannot keep information. The brain in humans is however the only source of storage. It has unlimited capacity and it can store information on any mainframe across the globe (WhitWorth & Ryu 6).
While computer systems can access stored information faster, human beings often forget bulk of information and can take some time to remember (Whitworth & Ryu 7).
