NAS – Network Attached Storage

Network Attached Storage (NAS) refers to a dedicated file storage device that provides data access to a network of clients. Unlike traditional storage solutions that are directly attached to a single computer, NAS devices connect to a network, allowing multiple users and devices to access and share files simultaneously. This architecture makes NAS an attractive Read More …

SAN – Storage Area Network

A Storage Area Network (SAN) is a specialized, high-speed network that provides access to consolidated block-level storage. SANs are designed to enhance storage devices’ accessibility, such as disk arrays and tape libraries, by connecting them to servers in a way that allows for efficient data transfer and management. Unlike traditional direct-attached storage (DAS), where storage Read More …

MAC – Mandatory Access Control

A Rigid Security Model Mandatory Access Control (MAC) is a security model where access to resources is determined by a central authority based on security labels assigned to both subjects (users, processes) and objects (files, resources). Unlike discretionary access control (DAC), where the owner of a resource can control who accesses it, and role-based access Read More …

SID – Security Identifier

A Security Identifier (SID) is a unique, variable-length alphanumeric string assigned by an operating system (OS), like Windows, to every security principal. A security principal can be a user, group, computer, or process that can be authenticated by the OS. SIDs are fundamental to how these systems manage access to resources. Here’s a more detailed Read More …

ACE – Access Control Entries

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 …

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 …
