Service Intro

What is a Computer Network ?

A computer network comprises two or more computers that are connected—either by cables (wired) or WiFi (wireless)—with the purpose of transmitting, exchanging, or sharing data and resources. You build a computer network using hardware (e.g., routers, switches, access points, and cables) and software (e.g., operating systems or business applications).

Geographic location often defines a computer network. For example, a LAN (local area network) connects computers in a defined physical space, like an office building, whereas a WAN (wide area network) can connect computers across continents. The internet is the largest example of a WAN, connecting billions of computers worldwide.

You can further define a computer network by the protocols it uses to communicate, the physical arrangement of its components, how it controls traffic, and its purpose.

Computer networks enable communication for every business, entertainment, and research purpose. The internet, online search, email, audio and video sharing, online commerce, live-streaming, and social networks all exist because of computer networks.

Types of Network

LAN (Local Area Network)
A LAN connects computers over a relatively short distance, allowing them to share data, files, and resources. For example, a LAN may connect all the computers in an office building, school, or hospital. Typically, LANs are privately owned and managed.
WLAN (Wireless Local Area Network)
A WLAN is just like a LAN but connections between devices on the network are made wirelessly.
WAN (Wide Area Network)
As the name implies, a WAN connects computers over a wide area, such as from region to region or even continent to continent. The internet is the largest WAN, connecting billions of computers worldwide. You will typically see collective or distributed ownership models for WAN management.
MAN (Metropolitan Area Network)
MANs are typically larger than LANs but smaller than WANs. Cities and government entities typically own and manage MANs.
PAN (Personal Area Network)
A PAN serves one person. For example, if you have an iPhone and a Mac, it’s very likely you’ve set up a PAN that shares and syncs content—text messages, emails, photos, and more across both devices.
SAN (Storage Area Network)
A SAN is a specialized network that provides access to block-level storage—shared network or cloud storage that, to the user, looks and works like a storage drive that’s physically attached to a computer. (For more information on how a SAN works with block storage
CAN (Campus Area Network)
A CAN is also known as a corporate area network. A CAN is larger than a LAN but smaller than a WAN. CANs serve sites such as colleges, universities, and business campuses.
VPN (Virtual Private Network)
A VPN is a secure, point-to-point connection between two network end points (see ‘Nodes’ below). A VPN establishes an encrypted channel that keeps a user’s identity and access credentials, as well as any data transferred, inaccessible to hackers.

Signs Your Network Needs an Overhaul

Their Windows server, firewall/router, main network switch, access points, network cabling throughout, etc. will all be replaced (they’re either outdated, faulty or home/consumer class devices).

01.
You have an old, unmanageable infrastructure
Any equipment that’s been in place for eight years or more is simply too old, says William, a lead research analyst at Info-Tech Research Group. Eight-port small office/home office–class hubs, old Category-5 cabling and network speeds of less than 100 megabits per second, for example, are dated and should be upgraded. If possible, school networks should offer speeds of a gigabit or better, William adds. Ideally, network components should be centrally located in secure wiring closets rather than in classrooms. “You don’t want the edge layer in a classroom, because such equipment is prone to getting dirty, dropped or damaged,” William says. He recommends storing it in a physically secured closet instead.
02.
You don’t have a wireless network
“The future of networks is wireless, and we are going to see fewer blue cables,” William says. Particularly in a school environment, where users are nomadic and somewhat mobile, wireless access is becoming crucial. “Wireless is supplementing or displacing a lot of wired connections, at least in the higher education market, and it’s moving into K–12 as well,” confirms David Stein, principal of the Stein Technology Consulting Group. Consequently, school IT leaders should work to make their wireless local area network secure, resilient and reliable. It also should be centrally managed with some distributed infrastructure. Wireless 802.11n is the current standard to deploy, but a newer standard, 802.11ac, will offer gigabit wireless when it debuts in 2013.
03.
Your network is unreliable
When a school’s network screeches to a halt, the repercussions are huge. Teachers have to switch gears on the fly, students can’t do their work, administrators can’t save files, and everyone loses faith in technology. If you don’t know when part of your network is in trouble or is becoming increasingly unreliable, it’s a big tip-off that an upgrade is in order. “If you hit seven or eight years, you’ll start to see that ports or switches will start failing more regularly,” William says. “Even physical cables will start to fail if they’re that old.” “Wireless is supplementing or displacing a lot of wired connections, at least in the higher education market, and it’s moving into K–12 as well,” confirms David Stein, principal of the Stein Technology Consulting Group. Consequently, school IT leaders should work to make their wireless local area network secure, resilient and reliable. It also should be centrally managed with some distributed infrastructure. Wireless 802.11n is the current standard to deploy, but a newer standard, 802.11ac, will offer gigabit wireless when it debuts in 2013.
04.
Your network isn’t secure
Schools are legally and morally obligated to secure private student data, including grades and personal information. Security breaches expose a school not only to potential legal action, but also to viruses and other malware that can destroy or damage the network and the files that administrators, teachers and staff rely on to do their jobs. Disruptions of any kind indicate that your network is vulnerable. “If you aren’t aware of the traffic that’s passing through your network, and you don’t have visibility into where that traffic is going, then it’s probably time to think about upgrading and possibly adding some layers to the network,” William advises.
05.
Your network isn’t ready for the future
60 per cent of digital businesses will suffer a major service failure due to IT security teams’ inability to manage digital risk. Whether hackers are targeting your business apps or data directly or through end-point devices, you’re ultimately only as safe as the network that connects all these devices and your data. And some cyberattacks target the network directly, such as distributed denial of service attacks (DDoS) which use bots to flood traditional networks with countless requests until systems crash and render your online services unavailable to real customers. As a result, businesses now need security embedded into the network and across a growing number of devices, with a range of benefits: pre-emptive threat detection and protection, and secure access to cloud.

Who Does Networking Works ?

overview the example.

The wired or wireless connection of two or more computers for the purpose of sharing data and resources form a computer network. Today, nearly every digital device belongs to a computer network.

In an office setting, you and your colleagues may share access to a printer or to a group messaging system. The computing network that allows this is likely a LAN or local area network that permits your department to share resources.

A city government might manage a city-wide network of surveillance cameras that monitor traffic flow and incidents. This network would be part of a MAN or metropolitan area network that allows city emergency personnel to respond to traffic accidents, advise drivers of alternate travel routes, and even send traffic tickets to drivers who run red lights.A city government might manage a city-wide network of surveillance cameras that monitor traffic flow and incidents.

The Weather Company worked to create a peer-to-peer mesh network that allows mobile devices to communicate directly with other mobile devices without requiring WiFi or cellular connectivity. The Mesh Network Alerts project allows the delivery of life-saving weather information to billions of people, even without an internet connection.
