主板擴展槽圖解
A daughterboard is a circuit board that plugs into and extends the circuitry of the main board called motherboard. A daughterboard is connected directly to the motherboard. Unlike expansion cards, which connect with the motherboard using the bus and other serial interfaces, daughterboards are usually directly embedded through soldering. Like a motherboard, a daughterboard has sockets, pins, plugs, and connectors to be attached to other boards. Typically, daughterboards are released as a post-launch update to a motherboard or expansion card. For example, a MIDI daughterboard is used to add on the functionality of the sound card. Modern computers rarely have daughterboards. In the past, this was common.
子板是插入并擴展稱為母板的主板電路的電路板。 子板直接連接至母板。 與通過總線和其他串行接口與母板連接的擴展卡不同，子板通常通過焊接直接嵌入。 像母板一樣，子板具有要連接到其他板的插座，插針，插頭和連接器。 通常，子板作為發布后對主板或擴展卡的更新發布。 例如，MIDI子板用于添加聲卡的功能。 現代計算機很少有子板。 在過去，這很普遍。
The earliest microcomputers were made up of different circuit boards, each of which performed a different function. All of these circuit boards were attached to a single board which is designed for some power regulation circuitry and a group of connectors. This board was commonly called a “bus board” or “backplane.”
最早的微型計算機由不同的電路板組成，每個電路板執行不同的功能。 所有這些電路板都連接到一塊板上，該板設計用于某些功率調節電路和一組連接器。 該板通常稱為“總線板”或“背板”。
In 1976, Steve Wozniak demonstrated to the Homebrew Computer Club his newly designed computer which had a single circuit board that had nearly all the functions needed for an entire computer. His computer design became known as the Apple 1. This single board, which was the first” motherboard” held the power regulation circuitry, a microprocessor, RAM, ROM, display circuitry, and a keyboard interface. Advance examples of daughterboards include the common memory modules used in our computers and Trusted Platform Modules.
1976年，史蒂夫·沃茲尼亞克(Steve Wozniak)向Homebrew Computer Club展示了他新設計的計算機，該計算機具有單個電路板，幾乎具有整個計算機所需的所有功能。 他的計算機設計被稱為Apple1。這塊單板是第一個“主板”，具有電源調節電路，微處理器，RAM，ROM，顯示電路和鍵盤接口。 子板的高級示例包括我們計算機中使用的通用內存模塊和Trusted Platform Modules。
