Area Networks
This document defines and compares different types of area networks including LAN, WAN, WLAN, and WWAN. It discusses how LANs cover small geographic areas like homes or offices while WANs span broader regions. It also outlines considerations for creating a basic network using a network adapter and crossover cable. The document predicts future networks may include a global area network connecting the entire world wirelessly.
Chapter v network
There are three basic types of computer networks: local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). LANs connect computers within a limited area like a building or floor. MANs connect LANs within a town or city up to 50 miles wide. WANs distribute information across thousands of miles between thousands of users spanning cities and continents. Networks allow connected computers to share resources and information.
Sm1 Computer Networks
A computer network connects two or more computers together to share resources like hardware, data, and software. There are different types of networks including local area networks (LANs) that connect computers in the same building using hubs or switches, metropolitan area networks (MANs) that connect LANs within a city, and wide area networks (WANs) that extend over long distances using telephones lines, towers, satellites or fiber optics. Networks classify devices like bridges that connect network segments and routers that route messages between different networks.
Computer Networks
A computer network allows computers to communicate and share resources like hardware, software, and data. A local area network (LAN) connects computers within a limited geographic area, like a home or office, through cables or wirelessly. To connect to a LAN you need a username and password to access files on the network. The internet is a global system of interconnected computer networks that is accessible worldwide.
Types of network
Sarthak Srivastava's class discusses four types of computer networks: local area networks (LANs) which connect buildings near each other, metropolitan area networks (MANs) which connect an entire city, wide area networks (WANs) which connect locations in different cities or countries like the internet, and campus area networks (CANs) which connect local networks within a university.
Arpanet
Arpanet was a network developed by the Advanced Research Projects Agency of the United States Department of Defense during the Cold War to facilitate information sharing among researchers. Computer spam involves sending many meaningless emails to recipients, while the internet allows online connectivity between individuals globally as opposed to an intranet which is a private network within an organization. A router enables WiFi connectivity within a designated area by broadcasting signals to devices for internet access.
Communication networks
The document discusses different types of computer networks. It describes Local Area Networks (LANs) which connect computers in a small area like an office or building using cables. Wide Area Networks (WANs) connect computers over larger distances, such as between cities or countries, using telephone lines or satellites. Metropolitan Area Networks (MANs) operate over an intermediate distance, connecting multiple LANs within a city using fiber optic cables. LANs provide high data transmission speeds but can connect a limited number of computers. WANs and MANs allow communication over larger distances but have higher costs and lower transmission speeds than LANs.
BASIC NETWORKING TOPOLOGIES
the presentation is related to the very basic networking topologies and is mainly meant for students of grade 8 or 9.
Network topologies for management
There are three basic network topologies: bus, ring, and star. The bus topology shares a common connection but adding nodes reduces speed. Ring topology connects each node in a circle with data traveling in one direction. Star topology connects all nodes to a central hub or switch, so a failure of the central device takes down the whole network.
