Happy Birthday, #Ethernet!

Man, this article took me down memory lane lol. My networking days started with #10Base2, T-connectors, #ISA NICs, #tokenring topologies, and #Novell's IPX/SPX! #Thicknet was already old tech when I got into it in the mid to late 1980's. But I did learn about it at my local library! I wasn't even 10 yet!

Can you even imagine what a #terabit looks like? My past self wouldn't have even thought that was possible in his lifetime lol.

Thank you Bob Metcalfe! Our world literally would not be what it is without your invention.

From Megabits to Terabits: Ethernet Celebrates Its Birthday

Exactly fifty years ago, the first concept of the computer networks we know today as Ethernet was designed. It has evolved from a thick coaxial cable connecting computers in a single location to the most common way of connecting networks of all sizes via twisted pair and optical fibre.

前篇聊到了 #10BASE2
這篇來聊一下另外一個 10Mbps 的接取標準 #10base5

其實在過去有另外一個說法
10Base2 被稱為 #thinnet
而 10Base5 稱為 #thicknet
後者比前者約 5 年以前推出
兩者都是使用同軸電纜
並且都運行在 10Mbps

而 10Base5 使用的電纜線更加的粗
在使用上 10Base5 的概念更像是幹線的存在
同樣與 10Base2 一樣可以讓多個節點運行在同一個內網內
不過接取的方式有很大的不同

接入網路的接頭不是使用 #BNC 而是 #N端子 以外
還有另外一個接取方式稱為 #吸血鬼接口 Vampire tap
使用端子對同軸線纜進行穿刺再由收發器轉接為 #AUI 接口
電腦或是終端裝置再透過 AUI 線再接到 #網路卡

而後來 10Base2 出現
由於其低成本、線纜鋪設難度低以及接取的方式也簡單的多
也讓 10Base5 快速的退市

#10BaseT 的出現讓同軸電纜開始慢慢退出區域網路接取標準
