Question

What are the major differences that exist between the central computer and peripherals?

Answer 1

The two important terms discussed in this article are the ones that make sure communication is possible on the computer device and the person using it. It starts with the input given by the user and the output that comes along in various forms. System units are the main components of the computer and consists of all the interior parts that are present within the device. Whereas a peripheral is an ancillary device that performs the task of putting information into the system and then getting the feedback from the system.

The system unit is one of the main components of the computer and consists of all the interior parts that are present within the device. This tool includes all the systems such as a motherboard, central processing unit, random access memory and other parts. The primary purposes of this method are to ensure that all the complex calculations get performed correctly and result from complicated processes become apparent. It also takes into account all the parts in which the interior components held. If we talk about this part in layman terms, we call it the chassis or a tower that performs and holds all the main sections that become critical in the working processes. Around two-thirds of the total tasks that take place within the system go through the unit and makes for a complicated structure. This term is also generally used to create differences between a computer and the peripheral devices that connect to the input, such as a keyboard, a mouse, and monitor. They hold all the devices that the unit has and performs calculations that are requested by the person operating. These instructions entered through input devices, and the parts internally range from a microprocessor to the capacity. Every part of the equipment has its process and benefit and mostly has electronic structures that interact simultaneously to make the calculations work and then transfer the answers to the input device for the user to understand them. It is safe to assume that all the parts of the body will work on some wiring system.

A peripheral device is usually considered the tool that helps a human being to communicate with the computer. An easy way of explaining the term is that it is an ancillary device that performs the task of putting information into the system and then getting the feedback from the system. It is usually a computer mouse of the keyboard that is not normally part of the computing system but connected to it and works with the network due to the operating system. Three primary types of peripheral devices exist these days; the first ones are called input devices that interact with the computer and the user and sends data to the instrument. Such tools include a mouse or keyboard. Then come the output devices that provide the conclusion of the information that enters through input devices and displays are on the screen. An example of such kind of devices is a printer or monitor. The last ones are the touchscreens that provide both the input and output facilities at the same time. Tools of this nature also include cell phones and tablets from which people get their work done at faster speeds. Touchscreens are considered peripherals since they get connected to the computer, but the difference comes where they start working on their own without the requirement of a mouse or keyboard. Many other examples of such kind of tools are possible, such as digital cameras, from where we take pictures and then connect them to the computer for keeping the data, it also includes tools such as loudspeakers and webcams.

Answer 2

The major difference that exists between the central computer and peripherals is that the peripherals are electromechanical and electromagnetic devices while the central computer i.e., the CPU and memory are electronic devices.

Explanation:

• A central computer is a system that communicates with the peripherals connected to it.
• The peripherals are the auxiliary devices that are used to enter information into a computer for storage or processing and get the processed data out of the computer.
• The peripheral devices include keyboards, mouse, printers, scanners, monitors, webcams, headphones, etc.
• Peripherals attached to a computer need special communication links for interfacing them with the CPU.
• The communication link is required to resolve the differences that exist between the central computer and each peripheral.
• One major difference is that the peripherals are electromechanical and electromagnetic devices while the CPU and memory are electronic devices. Therefore, a conversion of signal values is needed for communication.
• The peripherals transfer data at a usually slower rate than the CPU and hence, a synchronization mechanism is required.
• Data codes and formats in the peripherals are different from the word format in the central computer.
• The operating modes of peripherals also differ from each other and must be controlled so that the operation of other peripherals connected to the CPU does not get disturbed.
• The Interface Unit plays an important role in CPU and peripherals systems to supervise and synchronize all input and output transfers.
