Some models of desktop computers integrated the monitor and keyboard into the same case as the processor and power supply.
The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these. [1] Some computer hardware devices, such as a touchscreen, can both send and receive data through the interface, while others such as a mouse or microphone may only provide an interface to send data to a given system.

Ethernet standards require electrical isolation between the networked device (computer, phone, etc.) and the network cable up to 1500 V AC or 2250 V DC for 60 seconds. [113] USB has no such requirement as it was designed for peripherals closely associated with a host computer, and in fact it connects the peripheral and host grounds.
In computing and telecommunications, a character is a unit of information that roughly corresponds to a grapheme, grapheme-like unit, or symbol, such as in an alphabet or syllabary in the written form of a natural language. [1] Examples of characters include letters, numerical digits, common punctuation marks (such as "." or "-"), and whitespace.
