What are the causes of jitter?

Jitter refers to the variability in packet arrival times within a network, which can result in inconsistent data transmission and affect real-time applications such as VoIP calls, video conferencing, and online gaming. Several factors contribute to jitter, including network congestion, packet buffering delays, routing inefficiencies, and fluctuations in network traffic. Network congestion occurs when data … Read more

What is the main purpose of the ACL?

The main purpose of an Access Control List (ACL) is to regulate and manage access to resources within a computer network or system. ACLs define rules or conditions that determine which users, devices, or processes are permitted or denied access to specific resources based on predefined criteria. This granular control helps organizations enforce security policies, … Read more

How does CDN improve performance?

Content Delivery Networks (CDNs) improve performance by reducing latency and enhancing content delivery speed for users accessing web content from various locations globally. CDNs achieve this by caching content, such as images, videos, scripts, and other web assets, on servers strategically distributed across multiple geographical locations. When a user requests content, the CDN automatically directs … Read more

What is a router table used for?

A router table is primarily used in woodworking to enhance the versatility and precision of handheld routers. It serves as a stable platform where the router is mounted upside-down beneath the table, allowing woodworkers to guide the material over the router bit instead of maneuvering the tool manually. The router table provides a flat surface … Read more

What is subnet and why it is used?

A subnet, short for subnetwork, is a logical subdivision of an IP network. It is used to divide a large network into smaller, more manageable segments to improve efficiency, security, and performance. The primary purpose of subnetting is to enhance network management and address allocation. By dividing a large network into smaller subnets, administrators can … Read more

What are the advantages of TFTP?

TFTP (Trivial File Transfer Protocol) offers several advantages that make it suitable for certain specific use cases. One of the main advantages is its simplicity. TFTP is lightweight and straightforward, focusing on transferring files with minimal overhead. It operates with fewer features compared to other file transfer protocols, which simplifies implementation and reduces the amount … Read more

What is the purpose of a routing table?

A routing table serves the purpose of providing a router with the necessary information to make decisions about how to forward data packets within a computer network. It contains a list of routes or paths to specific network destinations, along with associated metrics such as cost, hop count, or bandwidth. The routing table enables routers … Read more

What is the reason for custom subnet masks?

Custom subnet masks serve specific purposes in networking configurations, allowing administrators to tailor network segmentation to fit their organizational needs precisely. The reason for using custom subnet masks is primarily flexibility in defining the size of subnets within an IP network. Unlike standard subnet masks that follow conventional class-based addressing (Class A, B, or C), … Read more

What is the purpose of TACACS?

Purpose of TACACS: TACACS (Terminal Access Controller Access-Control System) is designed to provide centralized authentication, authorization, and accounting (AAA) services for network devices. Its primary purpose is to control access to network resources by verifying the identity of users attempting to connect to or use network services. TACACS enables administrators to manage user access policies … Read more

What is the function of TFTP?

The function of TFTP (Trivial File Transfer Protocol) is to provide a simple and lightweight mechanism for transferring files between client and server devices over a network. TFTP operates on UDP (User Datagram Protocol) and is designed for situations where basic file transfer capabilities are needed without the overhead of more complex protocols like FTP. … Read more
