What is VLSM?
Variable Length Subnet Masking (VLSM) is a technique used in computer networking to allocate IP addresses efficiently by dividing a network into smaller subnets of varying sizes. It is an extension of the traditional subnetting method, which divides a network into fixed-size subnets. In traditional subnetting, all subnets within a network have the same subnet

What is joining networks through super netting?
Joining networks through the process of super netting is a fundamental concept in computer networking, specifically in the realm of Internet protocols and IP addressing. Super netting, also known as route aggregation or route summarization, is a technique used to combine multiple smaller network blocks into a larger, more efficient block. This process helps to

Is classful networking still relevant?
Classful networking, also known as class-based networking, was a method used in the early days of computer networking to allocate IP addresses. However, with the introduction of classless inter-domain routing (CIDR) and the depletion of IPv4 addresses, classful networking has become less relevant in modern network architectures. In classful networking, IP addresses were divided into

What is CIDR notation?
CIDR (Classless Inter-Domain Routing) notation is a method used in computer networking to represent IP addresses and their associated network prefixes. It is an efficient and flexible way to allocate and manage IP address space, allowing for more efficient routing and addressing within networks. CIDR notation provides a concise and standardized way to express the
What is the classification of IP addresses?
The classification of IP addresses, in the context of computer networking and Internet protocols, refers to the categorization and organization of IP addresses. IP, or Internet Protocol, is a fundamental protocol that enables communication between devices over the internet. IP addresses play a important role in identifying and locating devices on a network. Understanding the

What is an IP address and a MAC address?
An IP address (Internet Protocol address) and a MAC address (Media Access Control address) are important components in the field of computer networking. They serve different purposes and operate at different layers of the networking stack. In this explanation, we will consider the detailed and comprehensive understanding of both IP and MAC addresses, highlighting their
What is required to support full duplex?
To support full duplex communication in computer networking, several requirements must be met. Full duplex refers to the ability of a network device to transmit and receive data simultaneously. This allows for faster and more efficient communication between devices. In order to achieve full duplex, certain conditions must be satisfied at the physical layer of
With which type of cable do you have to be especially careful of the bend radius?
In the field of computer networking, the physical infrastructure plays a important role in ensuring reliable and efficient data transmission. Cabling devices are an integral part of this infrastructure, providing the necessary connectivity between network devices. When it comes to handling cables, one must be particularly cautious about the bend radius. The bend radius refers
