السلام عليكم ورحمة الله وبركاته ..

أنا جديد العهد بعالم الشبكات .. وأثناء بحثى وقراءتى فى هذا المجال .. استعصت على بعض المصطلحات أرجو منكم المساعدة ..

ما معنى أو ما مفهوم لفظ Ethernet ..؟؟

وما هى ال network segment & network node

وقرات كلمة Base-10T .. أريد أن أفهم معنى هذا المصطلح أيضا ..

وجزاكم الله خيرا ..

رمضــ كريم ــان

هل هذه المصطلحات نادرة التداول إلى هذا الحد ..؟؟

يا باشموهندسين انا فعلا محتاج الرد ضرورى .. أرجو المساعدة ..

Ethernet اليك ادناه ما تعنيه هذه الكلمة
Ethernet is a family of frame-based computer networking technologies for local area networks (LANs). The name comes from the physical concept of the ether. It defines a number of wiring and signaling standards for the physical layer, through means of network access at the Media Access Control (MAC)/Data Link Layer, and a common addressing format.

network segment & network node
network segment networking
A part of an Ethernet or other network, on which all message traffic is common to all nodes, i.e. it is broadcast from one node on the segment and received by all others. This is normally because the segment is a single continuous conductor, though it may include repeaters(?).
Since all nodes share the physical medium, collision detection or some other protocol is required to determine whether a message was transmitted without interference from other nodes. The receiving node inspects the destination address of a packet to tell if it was (one of) the intended recipient(s).
Communication between nodes on different segments is via one or more routers.

Base-10T
One of several adaptations of the Ethernet (IEEE 802.3) standard for Local Area Networks (LANs). The 10Base-T standard (also called Twisted Pair Ethernet) uses a twisted-pair cable with maximum lengths of 100 meters. The cable is thinner and more flexible than the coaxial cable used for the 10Base-2 or 10Base-5 standards.
Cables in the 10Base-T system connect with RJ-45 connectors. A star topology is common with 12 or more computers connected directly to a hub or concentrator. The 10Base-T system operates at 10 Mbps and uses baseband transmission methods.
