What is difference between a logical network and physical?
A physical network is different from a logical network. Logical networks are defined at the Network layer by the arrangement of the hierarchical addressing scheme. Physical networks represent the interconnection of devices on a common media. Sometimes, a physical network is also referred to as a network segment
Is A network interface card is sometimes referred to as a network adapter or a network card?
Yes
which network is known as network of networks?
The Internet is commonly referred to as the "network of networks." This description highlights its fundamental structure: a vast, global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It's a network made up of many smaller networks, including private, public, academic, business, and government networks, allowing data and information to be shared across diverse platforms.
Why the internet is sometimes described as a natwork of networks?
Each company has its network; at private homes, there are networks (even if it is only one computer connected to an ADSL router, for example). All of these networks are connected together, forming a larger network.
What is the network management systems?
Network management systems is referred to the combinations of hardwares and softwares used to monitor and administer a computer network or networks. It manages the network elements, also called managed devices.
What is the plural of network?
singular: network plural: networks
What do you mean by metropolitan area network?
A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network. Examples of metropolitan area networks of various sizes can be found in the metropolitan areas of London, England; Lodz, Poland; and Geneva, Switzerland. Large universities also sometimes use the term to describe their networks. A recent trend is the installation of wireless MANs.
What is the management systems?
Network management systems is referred to the combinations of hardwares and softwares used to monitor and administer a computer network or networks. It manages the network elements, also called managed devices.
What was the internets original name?
The internet, sometimes called simply "the Net," is a worldwide system of computer networks - a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers).

What Internet stands for?
Internet stand for inter connected network In short, Internet comes from Inter-NETwork, because the Internet is a network of networks ie an internet On another note, the Internet that we all use everyday is spelled with an upper-case I, and is referred to as 'The' Internet. There are many internets (networks of networks), but only one Internet.
What is hub in computer networks?
In computer networks, a hub is a basic networking device that connects multiple devices in a local area network (LAN). It's often considered a layer 1 (physical layer) device because it operates at the lowest level of the OSI (Open Systems Interconnection) model. A hub receives data packets from one device connected to it and then broadcasts the packets out to all other devices connected to the hub. It doesn't perform any processing or filtering of the data; it simply repeats the incoming data to all connected devices. This broadcasting method is known as "collision domain" networking, where all devices share the same communication channel. There are primarily two types of hubs: **Passive Hub**: A passive hub simply amplifies and rebroadcasts the signals it receives without any form of signal regeneration or data processing. It doesn't require any power source and is simply a physical connector for network devices. **Active Hub (or Powered Hub)**: An active hub, on the other hand, requires power and has the ability to regenerate signals. It typically includes additional features like signal regeneration and sometimes includes basic error detection. Hubs have largely been replaced by more advanced networking devices like switches, which offer improved performance and efficiency by selectively forwarding data packets only to the intended destination device rather than broadcasting to all devices on the network. However, hubs are still occasionally used in very simple network setups or for specific purposes where their characteristics are advantageous.
