In this introduction to networking, find out how laptop networks work, the design won’t to style networks, and the way to stay them secure.


What is a laptop network?


Electronic network includes two or additional computers that are connected—either by

cables (wired) or by Wi-Fi (wireless)—with the aim of transmittal, exchanging, or sharing information and resources. You build an electronic network exploitation hardware (e.g., routers, switches, access points, and cables) and software system (e.g., operational systems or business applications).

Geographic location typically defines an electronic network. As an example, a LAN (Local Area Network) connects computers in an exceedingly outlined physical area, like Associate in Nursing , whereas a WAN (Wide Area Network) will connect computers across continents. The web is that the largest example of a WAN, connecting billions of computers worldwide.

You can additional outline an electronic network by the protocols it uses to speak, the physical arrangement of its parts, however it controls traffic, and its purpose.

Computer networks alter communication for each business, amusement, and analysis purpose. The web, on-line search, email, audio and video sharing, on-line commerce, live-streaming, and social networks all exist thanks to Laptop networks.

Computer Network Sorts

As networking wants evolved, thus did the pc network sorts that serve those wants. Here are the foremost common and wide used electronic network types:

LAN (Local Area Network): A computer network connects computers over a comparatively short distance, permitting them to share information, files, and resources. As an example, a computer network might connect all the computers in Associate in Nursing , school, or hospital. Typically, LANs are in camera closely-held and managed.

WLAN ( Wireless Local Area Network ): A |WLAN| wireless fidelity | Wi-Fi |local area network |LAN| is simply sort of a computer network however connections between devices on the network are created wirelessly.

WAN (Wide Area Network): Because the name implies, a WAN connects computers over a large space, like from region to region or perhaps continent to continent. The web is that the largest WAN, connecting billions of computers worldwide. You may generally see collective or distributed possession models for WAN management.

MAN (Metropolitan Area Network): MANs are generally larger than LANs however smaller than WANs. Cities and government entities generally own and manage MANs.

PAN (Personal Area Network): A PAN serves one person. as an example, if you’ve got Associate in Nursing iPhone and a Macintosh, it’s terribly seemingly you’ve discovered a PAN that shares and syncs content—text messages, emails, photos, and more—across each devices.

SAN (Storage Area Network): A SAN may be a specialized network that gives access to block-level storage—shared network or cloud storage that, to the user, appearance and works sort of a storage drive that’s physically connected to a laptop. (For additional data on however a SAN works with block storage, see Block Storage: an entire Guide.)

CAN (Campus Area Network): A CAN will is additionally called a Company Area Network. CAN is larger than a computer network however smaller than a WAN.

VPN (Virtual Private Network): A VPN may be a secure, point-to-point affiliation between 2 network finish points . A VPN establishes Associate in nursing encrypted channel that keeps a user’s identity and access credentials, further as any information transferred, inaccessible to hackers.
