What are the 4 types of networks?
LAN is a network that usually connects a small group of computers in a given geographical area.
MAN is a comparatively wider network that covers large regions- like towns, cities, etc.
The WAN network spans to an even larger locality.
It has the capacity to connect various countries together..
What is a modem in computer network?
A modem is a network device that both modulates and demodulates analog carrier signals (called sine waves) for encoding and decoding digital information for processing.
Modems accomplish both of these tasks simultaneously and, for this reason, the term modem is a combination of “modulate” and “demodulate.”.
What is a router in a computer network?
A router is a networking device that forwards data packets between computer networks.
Routers perform the traffic directing functions between networks and on the global Internet.
Data sent through a network, such as a web page or email, is in the form of data packets..
What is a router in a computer network?
The OSI reference model describes the functions of a telecommunication or networking system, while TCP/IP is a suite of communication protocols used to interconnect network devices on the internet.
TCP/IP and OSI are the most broadly used networking models for communication..
What is the primary purpose of a gateway in a computer network?
Gateways serve as an entry and exit point for a network as all data must pass through or communicate with the gateway prior to being routed.
In most IP-based networks, the only traffic that does not go through at least one gateway is traffic flowing among nodes on the same local area network (LAN) segment..
What type of network is LAN MAN WAN?
A router is a networking device that forwards data packets between computer networks.
Routers perform the traffic directing functions between networks and on the global Internet.
Data sent through a network, such as a web page or email, is in the form of data packets..
- Advantages of computer networking
File sharing - you can easily share data between different users, or access it remotely if you keep it on other connected devices.
Resource sharing - using network-connected peripheral devices like printers, scanners and copiers, or sharing software between multiple users, saves money.
