They must select, install, and maintain network hardware, have a clear understanding of network architecture, and maintain servers. They may also provide network security and basic technical support. Good communication skills and knowledge of business practices are also […]
A network finder detects wireless networks nearby, used by laptop users and hackers. Hardware detectors emit lights to indicate active networks, while software programs scan for available networks. Wardriving is a form of wireless hacking, and advanced equipment can detect hidden networks. Unauthorized access to private networks is illegal. A network finder is a piece […]
A virtual network adapter connects electronic devices through software for secure communication. It is non-physical and used for virtual private networks (VPNs) in large organizations and government agencies. Installation involves configuring the system and connecting to the network through the computer’s Control Panel. A virtual network adapter is a technological system that helps connect computers […]
Setting up a home network can be easy with proper preparation. Determine if you need wired or wireless, purchase a router, and follow manufacturer instructions. Older laptops may need a wireless adapter. Setting up a home network setup can be complicated, but with a few simple steps, you can have a home network complete in […]
UMTS is a 3G wireless network that provides high-bandwidth voice and data services globally. It evolved from the 3GSM system and uses WCDMA and HSPA. UMTS is packet switched, has higher bandwidth, and offers different QoS target data rates and classes of service. LTE and WiMAX are 4G networks that developed from UMTS. UMTS is […]
The Von Neumann architecture uses a single processor and isolated memory banks, while neural networks have thousands of parallel nodes storing memories in interconnections. Neural networks are used by animal brains and handle noisy data better. In feedforward neural networks, data moves through layers to an output level. Back propagation limits signals from previous layers. […]
Home network computers are necessary for households with multiple devices. A router and Ethernet cables are needed for a wired network, while a wireless network requires a wireless router and adapter for each device. Security options are available to prevent unauthorized access. Sharing settings can be established to access items on the network from any […]
Wireless networks connect computers and peripherals without wires, allowing for easy communication. The 802.11 standard is used by almost all wireless networks, with subsections indicating speed and technology. Newer standards, such as 802.11(g) and 802.11(n), offer increased range and speed. WiMax is another type of wireless network that can extend for hundreds of miles, while […]
Convolutional neural networks are artificial neural networks that simulate brain activity, often used to mimic human or animal vision. They can recognize different features and have filters for certain ranges of light. Applications include facial recognition and security. Scientists continue to work on achieving greater complexity. A convolutional neural network is a certain type of […]
A bus network is a computer network where all devices share the same wired connection. Data travels to each computer on the network, but cable loss can occur. Only one computer can send data at a time, and a cable break affects the entire network. Bus networks are less expensive and useful for smaller networks, […]
A network structure in computer science refers to anything related to a computer network, including design, implementation, and usage. It can be viewed from an architect’s, business, or user’s perspective. The physical structure consists of cables, switches, and workstations, and can be categorized as LAN or WAN. The business aspect involves monitoring and cost management. […]
Network migration involves moving data and programs from one network to another for upgrades or merging. It can be due to security issues, corporate restructuring, or increased storage needs. Network migration can keep the same operating system but change data access. It can also improve data security and allow for cloud-based networks, enabling remote access […]
An integrated network card connects a computer to a network, either wired or wireless. It may have an RJ45 port for Ethernet cables or a built-in receiver for WiFi. Different standards exist for wireless communication, and external adapters can be used if necessary. Mobile broadband adapters are also available. Aftermarket adapters are easy to find, […]
Network management software comes in three types: antivirus, internal messaging, and server-based. All aim to consolidate entities into a single server, increasing security and making maintenance easier. They also monitor network functionality and connectivity, with specialized software available for healthcare and commercial industries. There are three different types of network management software. Potential users can […]
A wireless local area network (WLAN) uses radio waves to connect two or more computers, while a wired LAN uses Ethernet cables. The server connects to the DSL modem and clients require wireless NICs. WLANs offer convenience and flexibility, but require protection against intrusion and can be slower and less reliable than wired networks. The […]
To test a network card, ping a popular website from the command line to check response time, packets sent/received/lost. Check device properties or IP configuration for issues. Diagnostic tools can help. The usual reason people test a network card is to find out if it works properly and if it allows the computer to access […]
Network sniffing is a technique that uses hardware and software to intercept and analyze data packets on a network. It can be used for legitimate purposes like troubleshooting, but is often associated with hackers. Sniffing can be done internally or externally, and can reveal information about network hardware and security vulnerabilities. Network sniffing is a […]
Fixing a missing network card can be simple by updating or installing drivers, checking hardware properties, and performing a repair install. If the problem persists, the device may need to be replaced. A missing network card can be caused by several problems, and fixing the problem is usually quite simple. One of the most common […]
A base mesh is a simple 3D model used as a placeholder for testing purposes. It consists of a wireframe connected by polygons and is often low in detail and texture. Base meshes are freely available online and are useful for quick renders and animation testing. A base mesh is an object that has been […]
