Ad hoc networks are created for a specific purpose and consist of wireless devices that communicate directly with each other. They don’t go through a central hub and can be closed or shared with a public or private network. They are commonly used for portable video game systems and can be thought of as a […]
A storage area network (SAN) is a network of disk arrays, tape libraries, or optical jukeboxes connected by switches. SANs simplify storage device administration, allow multiple servers to access a single SAN, and are designed for disaster recovery. They have their own file system and can be connected through Fiber Channel or iSCSI technology. A […]
It’s best to use external network adapters for laptops, either wired or wireless, that connect through USB ports. Installing hardware inside a laptop is complicated and may void the warranty. Check if your laptop already has an Ethernet or wireless adapter before purchasing one. Look for well-reviewed adapters online. Choosing the best network adapter for […]
The Network Access Point (NAP) system was developed by the National Science Foundation (NSF) to replace the NSFNet. It allowed different network service providers to exchange information and connect their networks, leading to the formation of the modern Internet. The NAPs were later replaced by Internet Exchange Points (IXPs). A network access point (NAP) is […]
Computer network cables come in two types: unshielded twisted pairs (UTP) and shielded twisted pairs (STP). UTP is the most common type, with six categories based on data rate. STP is older and less popular, used mainly in servers and mainframes. Different cables are optimized for different uses and can vary in size and thickness. […]
Computer network cables come in two types: unshielded twisted pairs (UTP) and shielded twisted pairs (STP). UTP is the most common and is divided into six categories based on data rate. STP is older and used in Token Ring networks. Different cables are optimized for different uses and can come in various sizes and thicknesses. […]
A network manager’s resume should include contact information, relevant work experience, educational background, and professional references. List proficiency in managing networks and include specialist or freelance work. Use a professional email address and list positions in reverse chronological order. On your network manager’s resume, you’ll need to provide potential employers with your up-to-date contact information, […]
A managed care network is a group of healthcare providers that have contracted with an insurance company to provide services at fixed rates. The insurance company sets rate limits and patient contributions for each procedure, and providers agree to these terms. Patients may have a deductible and a co-pay, and there may be layers of […]
A ring network is a chain of network devices physically or logically linked together in a ring topology. Dual-ring networks provide redundancy, but information travels slower. Ring networks are still used in fiber optic networks, despite being replaced by Ethernet for token ring technologies in the 1980s. A ring network is a network of two […]
Network administrators build, maintain, and troubleshoot computer networks, which are essential for businesses and homes. They set up networks, maintain them, and provide employee training. Troubleshooting involves diagnosing and correcting problems at both individual and network levels. Collaboration is often necessary for complex issues. Network administrators are usually responsible for a wide variety of computer […]
Computer network security jobs are available in-house at large corporations or as a consultant. These positions involve securing and testing networks against potential attacks and can lead to internal advancements or self-employment opportunities. While there are a few different types of computer network security jobs, most of them are available in-house at a company or […]
Regularly update network card drivers, and consider upgrading hardware if experiencing slow internet or connectivity issues. Start by checking modem and router, then try a software update. If problems persist, physically upgrade the network card to a newer one that can handle faster speeds. How often you should update a network card depends on the […]
Computer network security software aims to protect a network and its data from various threats. This includes anti-virus, anti-malware, and anti-spyware software, as well as backup and encryption software. Properly configured web browsers and firewall software can also contribute to network security. OS security patches are also important. A computer network is a connected system […]
Mesh networks use distributed nodes to provide reliable and extended wireless coverage. They are ideal for providing free, ubiquitous internet access. Increasing the number of nodes is the only way to improve coverage, and mesh networking is the solution. Mesh networks have attracted attention since wireless technology became accessible, with many companies offering mesh networking […]
A computer database is organized in tables with a parent-child relationship. A network model database allows for multiple parent and child tables, resulting in a more natural graphical structure. It allows for a more realistic representation of the relationship between tables, but is largely obsolete in modern database design. Relational databases allow end users to […]
Network adapter software includes drivers to recognize and connect to networks, as well as programs for managing connections and monitoring misuse. It is essential for wireless adapters and can include utilities for handling multiple network profiles and passwords. There are several types of network adapter software available, and the programs you typically use depend on […]
Mobile ad hoc networks (MANET) allow wireless interconnection of devices, with each device acting as a node. MANETs are self-configuring and can be useful in applications such as ad hoc vehicular networks (VANET) and intelligent ad hoc vehicular networks (InVANET) for traffic data, efficient vehicle-to-vehicle communication, and off-grid communication. InVANET can also use Wi-Fi technologies […]
Artificial neural networks mimic the human brain using simulated neurons and stimuli. They are used in gaming, robotics, and data processing, and use learning models such as supervised, unsupervised, or reinforced learning. Fuzzy logic helps fill gaps in data for better results. Machine committees provide multiple opinions for decision modeling. An artificial neural network is […]
When choosing a social networking platform, consider friend-finding capabilities, privacy features, ease of use, and popularity. Try it yourself and customize your profile for privacy. The platform should be easy to navigate and popular for engagement. When choosing a social networking platform, you should consider friend-finding capabilities, privacy features, and ease of use. Another thing […]
Choosing the right social network involves finding a balance between useful features and time-consuming distractions. A popular network is usually better, but a smaller one may be suitable for specific interests. Consider the level of effort, safety, and privacy before choosing a site. It’s also possible to maintain a social network without a service through […]
