any device — for example a computer, printer, or phone — that is linked to a larger network and can send or receive data

例句

Each node on the office network has its own IP address so data can reach the right device.

公司網路上的每個節點都有自己的 IP 位址，資料才能正確送達。

node + IP address (networking context)

When a single node fails in a mesh network, the other devices find a new path to communicate.

在網狀網路中，如果某個節點故障，其他裝置會自動找到新的通訊路徑。

同義詞
  • device

    broader term for any piece of hardware; does not specifically imply network connection

  • terminal

    historically meant a dumb terminal; now less common than 'node' for general network devices

  • host

    a computer that provides services on a network; more specific than 'node'

  • workstation

    a computer used by a person, not any network device

文法句型

network + node

node + on + [network]

[adjective] + node

用法筆記

In computing, any device with a unique network address qualifies as a node — not just computers but also printers, routers, smart sensors, and phones. The term is especially common when discussing network topology.

常見錯誤

❌My phone is on the node.
✅My phone is connected to the network as a node.
💡A node is a role a device has on a network, not a physical location you connect 'to.'

2. a point or location where multiple lines, routes, or systems meet and connect to

釋義

交會點；樞紐

多條線路或系統交會處

a point or location where multiple lines, routes, or systems meet and connect to one another

例句

London is a major transport node where several railway lines and motorways converge.

倫敦是一個重要的交通樞紐，多條鐵路和高速公路在此匯集。

major transport node (common collocation)

The telecommunications network relies on switching nodes that route data between cities.

電信網路依靠交換節點在城市之間傳送資料。

同義詞
  • junction

    more concrete; used for physical roads, railways, or pipes meeting

  • hub

    implies a central, busy point of activity rather than any connection point

  • intersection

    limited to lines or roads crossing; does not convey multiple systems

  • nexus

    more formal or literary; suggests a central focus of connections

反義詞
  • endpoint

    a terminal point rather than a connecting point

文法句型

[adjective] + node

node + in + [system]

node + of + [network]

用法筆記

Frequently used in transport, telecommunications, and data systems. Unlike 'junction' (mainly physical roads or rails) or 'intersection' (roads crossing at grade), 'node' includes abstract or system-wide points where connections happen.

常見錯誤

❌Turn left at the next road node.
✅Turn left at the next road junction.
💡For physical roads, 'junction' or 'intersection' is natural; 'node' sounds overly technical.

3.名詞B2
釋義

結；結節

體內小型組織塊，多屬免疫系統

a small rounded lump of bodily tissue, often part of the immune system, that filters fluids or helps fight infection

例句

swollen node (common symptom description)

Lymph nodes throughout the body help trap bacteria and other harmful particles.

全身的淋巴結能攔截細菌和其他有害微粒，幫助人體防禦。

lymph node definitional collocation

同義詞
  • gland

    often confused with node; glands secrete substances, whereas nodes filter fluid and house immune cells

  • nodule

    a small rounded lump; can apply to tissue but less specific than 'node' in anatomy

  • lump

    non-technical term for any abnormal swelling; less precise

文法句型

lymph + node

[adjective] + node

node + in + [body part]

用法筆記

Most commonly encountered in the phrase 'lymph node.' Swollen or tender nodes often indicate the body is fighting an infection. The term also refers to other small tissue masses such as nerve nodes or sinus nodes.

常見錯誤

❌He had swollen nodes on his arm muscles.
✅He had swollen lymph nodes in his armpit.
💡Nodes are small tissue masses, most commonly lymph nodes found in the neck, armpits, and groin — not on muscles.

prune above a node (gardening technique)

Each node on the bamboo stem can produce a new shoot if the conditions are right.

同義詞
  • joint

    less precise; suggests a flexible connection, whereas node refers to a specific growth point on a stem

  • knot

    informal; can mean a hard lump on a tree trunk, but not the regular growth point of a stem

  • swelling

    describes the visible bump but not the botanical function

文法句型

node + of + [plant]

[plant] + node

用法筆記

The node is often visible as a slight swelling or ring on the stem. Gardeners cut just above a node when pruning because that is where new growth will emerge.

常見錯誤

❌My rose bush has nodes on its leaves.
✅My rose bush has nodes on its stem.
💡Nodes form on the stem where leaves attach, not on the leaf itself.
