網路原理(一) Section 5.1

IEEE 802.2
IEEE 802.2，一種工業標準，被包含在IEEE 802標準之中，是電腦網路中的軟體元件標準。它定義了邏輯鏈路控制層，是OSI模型中數據鏈路層的上層部份。

IEEE 802.3
IEEE 802.3是IEEE制定在雙工模式(Full Duplex)中提供流量控管的機制(Flow Control) ，相關規格已制定於IEEE Std 802.3-2002(Annex 31B)中。

LLC Sublayer
The Ethernet LLC sublayer handles the communication between the upper layers and the lower layers.

MAC Sublayer
MAC constitutes the lower sublayer of the data link layer.

Data Encapsulation
The data encapsulation process includes frame assembly before transmission, and frame disassembly upon reception of a frame.

Frame Delimiting
The framing process provides important delimiters that are used to identify a group of bits that make up a frame.

Cyclic Redundancy Check
循環冗餘校驗（英语：Cyclic redundancy check，通稱「CRC」）是一種根據網路數據封包或電腦檔案等數據產生簡短固定位數驗證碼的一種散列函數，主要用來檢測或校驗數據傳輸或者保存後可能出現的錯誤。

Carrier Sense Multiple Access (CSMA)
載波偵聽多路存取（英語：Carrier Sense Multiple Access，縮寫：CSMA）是一種媒介存取控制（MAC）的協定。

Ethernet II
Ethernet II is the Ethernet frame format used in TCP/IP networks.

Frame Check Sequence (FCS)
The minimum Ethernet frame size is 64 bytes and the maximum is 1518 bytes. This includes all bytes from the Destination MAC Address field through the Frame Check Sequence (FCS) field. 

Preamble
The Preamble field is not included when describing the size of a frame. 

runt
小;迷你

Collision Fragment
Any frame less than 64 bytes in length is considered a “collision fragment” or “runt frame” and is automatically discarded by receiving stations.

Jumbo ; Baby Giant Frame
Frames with more than 1500 bytes of data are considered “jumbo” or “baby giant frames”.

Hexadecimal
16進制

Organizationally Unique Identifier (OUI)
The IEEE assigns the vendor a 3-byte (24-bit) code, called the Organizationally Unique Identifier (OUI).
