A network operating system controls software and hardware on a network, allowing multiple computers to communicate and share resources. Networks consist of computers connected to a central hub, with a file server storing data. Network administrators manage the system and may receive certifications for specific types of NOS. Peer-to-peer and client/server networks can be overseen […]
A network port can refer to a hardware access point, physical connection, or software system that divides network traffic. It allows computers to handle multiple activities simultaneously and follows guidelines with numbered ports. A network port is a common way to refer to three different things. Network access points, such as a home router, are […]
A network server provides shared resources to workstations and other servers on a computer network, including disk space, hardware access, and email services. It simplifies data, communication, and information on a massive scale, and can be almost any device. Servers have more powerful components than individual workstations, and can simplify management tasks for system and […]
Network security protocols, such as encryption, protect data and communications during transit. They are necessary for secure e-commerce and to prevent interception, modification, and hijacking of communications. Secure File Transfer Protocol (SFTP) and Secure Sockets Layer/Transport Layer Security (SSL/TLS) are commonly used to secure file transfers and email communications. SSL/TLS is also used for HTTPS […]
A USB network adapter allows for standard or wireless internet connection on a computer, with easy installation. Wireless adapters are useful for older computers without built-in Wi-Fi, while wired adapters are useful in buildings without wireless. Different adapters work with different operating systems and require driver downloads. The adapter must remain connected to maintain a […]
Centralized network management allows for the efficient management of complex corporate computer networks from a single control station or server. It includes performance monitoring, security, load balancing, and traffic management. Specialized software can help monitor and manage all components, set policies, and predict performance. It also allows for control over user access and software installation. […]
A wired network adapter connects a computer to a LAN using an Ethernet cable. It can be internal or external, and provides faster speeds and better security than wireless. External adapters are easy to install and require a device driver. Faster LAN speeds do not increase internet speed. A wired network adapter is a hardware […]
Network diagnostics are used to troubleshoot internet problems and determine a computer’s network configuration. They can be performed using hardware or software tools, and provide information such as connection speed, IP address configuration, and blocked traffic. Windows users can access a built-in network diagnostic tool in Internet Explorer. A network diagnostic is a procedure used […]
An ACL network uses routers and switches with predetermined access permissions. Data packets are filtered and evaluated against an access control list (ACL) containing access control entries (ACEs). Planning is crucial to avoid being locked out. ACLs are useful for restricting traffic and monitoring packets. An ACL network is really like any other computer network, […]
A logical network diagram shows how electronic components interact in a network, including domain names, IP addresses, and communication. It’s more useful than a physical diagram. Network diagrams can be created using simple shapes or software applications with pre-drawn templates and symbols. A logical network diagram illustrates the network architecture of a group of interconnected […]
A network driver is software that controls a device connecting a computer to a network, providing user feedback and converting information into usable formats. It acts as an interface between the operating system and hardware, abstracting technical differences. Updating and troubleshooting network drivers is important for stability and security. A network driver is a software […]
A network administrator assistant helps configure and monitor a company’s computer network, identifying needs, designing and configuring the network, training staff, troubleshooting, and making network modifications. They require computer skills, innovative thinking, and problem-solving skills, and at least a bachelor’s degree in information systems or information technology. A network administrator assistant helps configure and monitor […]
A grid code is a set of rules that regulate the distribution of electricity to prevent outages and surges. It applies to traditional and renewable energy producers and includes protocols for responding to failures and overloads. The code also contains proactive and reactive behaviors to ensure stability and reliability. A grid code is a set […]
Net investment income is the total profit earned from investments after subtracting losses. It can come from various sources, including stocks, bonds, and mutual funds, and is calculated annually for tax purposes. Companies also calculate net investment income per share to inform shareholders and may pass on profits to investors as dividends. Net investment income […]
Equity is the value of a deceased person’s estate after expenses are deducted. Gross estate is the total value of the estate, including assets. The executor distributes net assets to beneficiaries according to the will. Inheritance tax laws vary, and estate planning may involve distributing assets before death or setting up a trust. An equity […]
Net neutrality is the principle that all internet data should be treated equally. It has become a policy goal in some countries, but its legal authority in the US is controversial. The principle prohibits internet providers from prioritizing one set of data over another, including format, means of transmission, and content. Proponents argue that it […]
Neural network applications use a set of processors to interpret data, similar to the human brain. They are used in various industries, including visual animation and government research. These applications have replaced older programming tools and could be used even more in the future. Neural network applications are software configurations that use a specific type […]
Systems Network Architecture was a proprietary networking protocol developed by IBM in 1974 for mainframe connectivity. It overcame communication port issues and allowed trunk bundles to connect, making it popular in the financial industry. Although outdated, it is still used in some companies today. Systems Network Architecture is a proprietary networking protocol owned and marketed […]
Gross profit is revenue minus cost of goods sold, while net profit is gross profit minus overhead expenses. Companies can increase profits by lowering costs in these two categories. Profitability is important for determining a company’s value and satisfying shareholders. Profit and loss statements and profit margin percentages can also be used to assess a […]
A network infrastructure is a set of interconnected computer systems that can be open or closed, wired or wireless. It includes individual computers, routers, switches, and protocols. Network security is important and can be controlled through firewalls and access control. A network infrastructure is an interconnected set of computer systems connected by the various parts […]
