A single Cisco router can have up to 21 virtual terminal lines. This lets many administrators work together. Network teams use these lines to manage devices securely. They can grant access to certain users or block others. For example, they might allow a level 15 username to access but block 10.1.1.3/24 from telnet sessions. vty…

In 1936, the first computer architecture was documented. This was 23 years before the term became common. It shows how fast technology advances in our digital world. CPU latency for disk storage is in milliseconds. Cache works in nanoseconds. This big difference shows why a clear plan is key. It helps hardware and software work…

It takes three steps to start sending data over TCP. But UDP does it all without a handshake. This shows how TCP and UDP work differently in networks. TCP makes sure data is reliable by checking for errors. But this makes it slower. UDP, on the other hand, sends data fast, even if some gets…

Did you know that nearly 50% of VPN users cite privacy and security as their primary reasons for hiding their online identity? In today’s digital age, protecting your network activity is more important than ever. One of the most effective ways to achieve this is by using an IP mask. An IP mask is a…

VMware ESXi shows a 10% to 14.5% better performance than Proxmox in CPU and memory use. This highlights a key difference between ESX and ESXi. Efficiency is a big factor in choosing between them in IT settings. VMware started with ESX, a strong service console. But, as needs changed, VMware updated to ESXi. ESXi is…

It’s amazing that technology from 1983 is used in many computers today. MBR, or Master Boot Record, is a key part of this. GPT, or GUID Partition Table, offers a stronger structure and more flexibility. This article will compare mbr vs gpt to help you understand why both are important. We’ll look at gpt vs…

An efficient network is key for modern businesses, where time is everything. Setting the default BGP local preference to 100 can change how traffic flows. This helps companies with many internet connections manage their data better, improving performance and saving money. In bgp routing, BGP stands out with its complex hierarchy of attributes. The bgp…

In networking, every second is key. OSPF routers send out Hello packets every 10 seconds. This shows how dedicated they are to keeping the network connected. If a Hello packet isn’t received for 10 seconds, network issues can grow. With a 40-second *Dead Interval* for some interfaces, mistakes can be costly. This makes learning about…

70% of network engineers use Ethernet loopback plugs to test connection quality. These tools detect faulty cables and ports. In dark fiber networks, they ensure signal integrity during activation and verify performance for critical systems like data centers and enterprise networks. Network technicians use fiber optic loopback cables for precise tests. They help avoid complex…

The loopback plug is a key tool for network reliability. It’s more than just a connector; it’s vital for network loopback tools. It helps data flow smoothly in our digital world. With more networks and phones, loopback plugs are more important than ever. They quickly find problems with ports. A silent port means there’s a…
