The Ethernet cable is being using on wired network. This is the most popular source of data communication between computer, routers, switches, firewalls and many other devices on a Local Area Network (LAN). In the current era, the Ethernet Cables are very common types of cables, which are being using in mostly wired network. Ethernet cable wiring is very important dialogue discussion, particularly if you have to prepare for the Cisco exams such as CCNA. Ethernet cables are actually constructed in two essential kinds known as solid and stranded. The Solid Ethernet cables is using to get enhanced communication performance and protection beside electrical interference, however stranded cables are less in performance and protection to bodily cracks and breaks making them further appropriately for travelers and portable devices. Usually Ethernet cables can sustain one or more industry standards as well as Category 5 (CAT5) and Category 6 (CAT6).

Data Link layer performs the process of combination of bits into bytes and bytes into frames. So, Data Link layer employs frames to summarize the packets which were received from the Network Layer for transmitting on a sort of media access. The function of Ethernet stations is to pass data frames between each other using a group of bits recognized as a MAC frame format. This detects errors from a Cyclic Redundancy Check (CRC) (Remember this is error detection, not error correction). The 802.3 frames and Ethernet frame are shown below. NOTE: Encapsulating a frame within a different type of frame is called tunneling.
