The Building Blocks of Permissions In the realm of Identity and Access Management, controlling who can access what is paramount. While Access Control Lists (ACLs) provide the structure for managing permissions, the individual permissions themselves are defined within Access Control Entries (ACEs). Understanding ACEs is crucial for IT students to grasp the fine-grained control that Read More …

CRC – Cyclic Redundancy Check
Cyclic Redundancy Check (CRC) is a widely used error-detecting code that helps ensure the integrity of data during transmission or storage. It is a crucial concept in networking and data communication, making it essential for new IT students to understand how it works and its applications. What is CRC? CRC is a method used to Read More …
FCS – Frame Check Sequence
A Frame Check Sequence (FCS) is an essential component in data communication protocols, serving as a method for error detection. It is a sequence of bits added to the end of a data frame, which allows the receiving device to verify the integrity of the data it has received. Understanding FCS is crucial for new Read More …
LCP – Link Control Protocol
The Link Control Protocol (LCP) is a critical component of the Point-to-Point Protocol (PPP), which is widely used for establishing direct connections between two network nodes. LCP plays a vital role in the setup, configuration, and management of PPP connections, making it essential for ensuring reliable and efficient data transmission over point-to-point links. Establishing Connections Read More …
PPP – Point-to-Point Protocol
Point-to-Point Protocol (PPP) is a widely used communication protocol that facilitates the transmission of data over point-to-point links. It is particularly important in networking because it provides a standard method for transporting various types of data, including IP packets, over direct connections between two devices. Understanding PPP is essential for new networking students, as it Read More …
IPX – Internetwork Packet Exchange
Internetwork Packet Exchange (IPX) is a networking protocol that was primarily used in the 1980s and 1990s, particularly in networks that utilized Novell NetWare operating systems. While it has largely been replaced by the more widely adopted Internet Protocol (IP), understanding IPX is important for new IT students, especially when studying the history of networking Read More …
MTU – Maximum Transmission Unit
Maximum Transmission Unit (MTU) is a fundamental concept in networking that refers to the largest size of a packet or frame that can be sent over a network. This size is specified in octets, which are eight-bit bytes. Understanding MTU is crucial for new networking students, as it plays a significant role in the efficiency Read More …
TTL – Time to Live
Time to Live (TTL), often referred to as hop limit, is a crucial mechanism used in computer networking to manage the lifespan of data packets as they traverse through a network. The primary purpose of TTL is to prevent data packets from circulating indefinitely, which can occur due to routing errors or network loops. By Read More …
