Neural network data mining uses artificial neural networks to extract data by recognizing patterns in databases. It has numerous practical uses, including analyzing trends in large corporations and extracting patterns from scientific research. It is also used in games, surveillance, and geographic systems. Neural network data mining is the process of collecting and extracting data […]
WiFi networks use radio waves to connect computers and share online access without cabling. They require a router and WiFi card or adapter, and use the IEEE 802.11 standard. Different generations of protocols exist, and components must support the same type to communicate. Certified components are recommended for business networks. Bluetooth networks use a weaker […]
Backbone networks connect various components of a network while maintaining their integrity. They allow multiple networks to be linked together for sharing data, but still function independently. They use wired and wireless connections and can include secondary options. They differ from the Internet backbone as they are closed unless proper credentials are used. Backbone networks […]
Resetting a network adapter can be done by physically removing the card and restarting the computer, or by uninstalling drivers and software. Resetting a modem and router can also fix internet connection issues. There are several ways to reset a network adapter, although the two most common ways include removing the adapter from your computer. […]
A personal network is a collection of devices without a centralized system, often created using mobile devices. It can use Bluetooth, Wi-Fi, or cables and can connect to the internet. Devices connect to a root hub and act as extensions of it. The only limitation is the transmission distance of individual components. A personal network […]
Network Utility is a program on Macs that provides information about a network and performs simple tasks. It has nine core functions, including Info, Netstat, AppleTalk, Ping, Lookup, Traceroute, Whois, Finger, and Port Scan. It can display network information, traffic information, routing tables, and open sockets. It also offers diagnostic functions for AppleTalk and allows […]
To troubleshoot network problems, identify the type of problem and change one thing at a time while taking clear notes. Start with physical network checks, then configuration and computer settings, and finally, software issues such as firewall installation. Avoid assumptions and follow a logical approach. To troubleshoot network problems, it’s important to have a basic […]
Replacing a network card involves uninstalling old software, physically removing the card, installing new software, and installing the new card. Consider compatibility with the computer and operating system, and whether to use an internal or external card. Uninstall old software, remove the old card, install new software, and install the new card. External cards may […]
A network interface adapter connects devices to a network, either wired or wireless. Wireless adapters require a compatible router and have a limited range. External adapters can be connected via USB and offer various connectivity options. Cellular network adapters are also available, but prices vary based on the generation of cellular service they support. Adapters […]
HSDPA is a mobile phone protocol that allows for faster connection speeds using a combination of channels. It provides fast and reliable wireless connection, with speeds up to 84 Mbit/s. HSDPA routers can create a Wi-Fi network, and latency is low enough for gaming and video conferencing. It is a viable alternative to wired connections […]
NIS is a client and server system that allows machines in a network to share configuration files. It centralizes administration of Unix systems and supports file sharing. NIS is an industry standard and was originally called Yellow Pages. Network information system, also known as NIS, is a client and server system based on remote procedure […]
The Network Security Toolkit (NST) is a free suite of open source applications for monitoring and maintaining network security. It comes as an ISO disk image with its own operating system and web user interface. It can be installed on an optical disc, USB flash drive, or a virtual machine. NST offers detailed network analysis, […]
Ethernet home networks connect computers and the internet using hardware and software protocols. They allow for simultaneous internet access and file sharing, but cables can be cumbersome. Wireless options exist, but wired networks are more secure. A router is often used to set up the network, and network adapters are needed for each computer. ISPs […]
A home network server provides services to devices in or outside the home, including file and print services, media services, and data backup. It can authenticate users and computers, run various operating systems, and serve media content. It doesn’t require enterprise-class hardware and needs a capable network interface card and an uninterruptible power supply. A […]
Network Behavior Analysis (NBA) monitors incoming and outgoing traffic to prevent harm to network components. It works with existing security protocols, constantly scans communications, and highlights unusual trends to improve overall network efficiency and security. Network Behavior Analysis, or NBA, is an approach to hardening the overall security measures employed with a given network. The […]
Network design ranges from small local area networks to complex corporate systems. Thoughtful design and informed decisions are crucial for functionality, including components that work together, computer security, and connection types. Reliability and redundancy are important, including power and web host uptime. Network traffic and required bandwidth and speed should also be considered. Network design, […]
The role of a network IT manager varies depending on the company size and type of business they support. They must have experience in network architecture, operating systems, hardware platforms, software applications, and be able to maintain network hardware and software. Their daily tasks depend on the job description, from troubleshooting individual computer systems to […]
Network analysis using graph theory is a management tool for breaking down projects into components or individual tasks. Network analytics can offer insight into network operations and detect problems before they occur. Organizations require accessibility, granularity, and visibility to effectively perform network analysis. This can be achieved through robust hardware and software, capturing and decoding […]
