Jitter in a processor refers to the variability or deviation in the time it takes for the processor to complete a given set of tasks. This can manifest as inconsistencies in task execution times, affecting the predictability and performance of the processor in time-sensitive applications. Jitter in a CPU specifically relates to the fluctuations in … Read more
Traceroute is a network diagnostic tool that traces the route that packets take from a source device to a specified destination, such as an IP address or hostname. It accomplishes this by sending packets with incrementally increasing Time-to-Live (TTL) values, forcing each router along the path to send back ICMP TTL exceeded messages. Traceroute then … Read more
Jitter in real time refers to the variability in the time delay experienced in transmitting data packets over a network. In real-time systems, such as video conferencing, online gaming, or VoIP (Voice over Internet Protocol) calls, jitter can cause disruptions because these applications rely on a consistent stream of data. Variability in packet arrival times … Read more
Latency about internet refers to the time it takes for a data packet to travel from the source to the destination and back. It is often called “ping” and is measured in milliseconds (ms). High latency can result in delays, affecting real-time applications like gaming, video conferencing, and VoIP calls by causing lag and interruptions. … Read more
Latency vs lag: Latency refers to the time it takes for data to travel from one point to another in a network, typically measured in milliseconds (ms). It is the delay between the sender and receiver. Lag, on the other hand, encompasses a broader concept that includes latency but also refers to any delay or … Read more
SD-WAN, or Software-Defined Wide Area Network, is a technology that simplifies the management and operation of a wide area network (WAN) by separating the networking hardware from its control mechanism. It enables the centralized management of network traffic and policies through software, providing greater agility, flexibility, and efficiency in connecting branch offices, data centers, and … Read more
WAN, or Wide Area Network, traditionally refers to a network that spans a large geographical area, connecting multiple local area networks (LANs) or individual devices across different locations. It typically relies on dedicated hardware such as routers and leased lines to transmit data between sites. SD-WAN, or Software-Defined Wide Area Network, is a newer technology … Read more
A MAC (Media Access Control) address is primarily used for identifying and communicating with devices within a local network. It serves as a unique identifier assigned to network interfaces, such as Ethernet cards or Wi-Fi adapters, by manufacturers. MAC addresses are used at the data link layer (Layer 2) of the OSI model to facilitate … Read more
The term “default gateway” refers to a network device or router that serves as an access point or intermediary between devices on a local network and external networks, such as the internet. It acts as the gateway through which networked devices can communicate with devices outside their immediate network segment. The default gateway is essential … Read more
The subnet mask for a /25 network is 255.255.255.128. This corresponds to 25 bits allocated for the network portion of the IP address, leaving 7 bits for host addresses within each subnet. This subnet mask effectively divides the IP address space into smaller subnetworks, each capable of accommodating up to 126 usable IP addresses. A … Read more
