The Data Link Layer is the second layer of the Open Systems Interconnection (OSI) model, which serves as a conceptual framework that standardizes communication system functions. This layer focuses on the reliable transfer of data between adjacent network nodes over a physical link.

A Deep Dive into the Architecture of the Internet It’s the single most transformative technology of our lifetime, yet most of us use it without a second thought. We send an email, stream a movie, or jump on a video call, and it just… works. But have you ever stopped…
Data Link Layer of OSI Model (Layer-2)
Data Link Layer of OSI Model (Layer-2)
Data Link Layer of OSI Model is the second layer in seven layer model. Data Link layer performs two very important functions of physical addressing and switching. Data link layer is the place where most LAN, Ethernet and wireless LAN technologies are defined. Each layer in OSI Model has its own duties & specific functions to perform so that it can support the layers above it. Below figure shows…

網路架構與簡介
現在這個時代不管是電腦也好，
手機也好都在使用網路，
何謂區域網路LAN呢？
國際電機電子工程師協會(IEEE, Institute of Electrical ,Electronics, and Engineering)曾經對區域網路給過定義：
區域網路是一個通訊系統，它允許適量彼此無關的電腦在適當的範圍內以適當的傳輸速率進行直接的通訊
常見的網路架構有：
星狀架構
匯流排架構
環狀架構
星狀架構
在星狀架構下有一個中央控制器，所有電腦都直接與它連接，任意兩台電腦的通訊都需經過中央控制器，由於中央集權的緣故，擁有較佳的管理特性，而中央處理器損壞也代表所有電腦間的通訊都將中斷。星狀架構能擴充為雪花狀架構(snowflake)。
匯流排架構
在匯流排架構下所有電腦都經過一條電纜線連接起來，訊號以廣播方式傳送，任意兩台電腦若損壞都不影響…

Data Link Layer - OSI Model
Data Link Layer – OSI Model
Data Link Layer – OSI Model-Data link layer performs the foremost reliable node to node delivery of information. It forms frames from the packets that area unit received from the network layer and provides it to the physical layer. It conjointly synchronizes the data that is to be transmitted over the info. Error dominant is well done. The encoded information area unit then passed to physical.

7 Networking Layers
The 7 layer burrito of #networking in terms for #developers
Open System Interconnection (OSI) model is a conceptual framework that defines how to implement network protocols. It was developed by the International Standards Organization (ISO) in order to standardize communication functions. The goal is interoperability of different systems through a standard protocol. The concept is based on the work of Charles Bachman at Honeywell Information Services.
