An electronic network could be a cluster of pcs joined to every different that allows the pc to speak with another computer and share their resources, data, and applications.

An electronic network may be categorized by its size. An electronic network is especially of 4 types:
1. LAN (Local Space Network)
2. PAN (Personal space Network)
3. MAN (Metropolitan space Network)
4. WAN (Wide Space Network)

LAN (Local Space Network)
A local space network (LAN) could be an assortment of devices connected along in one physical location, like a building, office, or home. A local area network may be little or giant, starting from a home network with one user to AN enterprise network with thousands of users ANd devices in a workplace or faculty. notwithstanding size, a LAN's single shaping characteristic is that it connects devices that square measure during a single, restricted space. In distinction, a large space network (WAN) or metropolitan space network (MAN) covers larger geographic areas. Some WANs and MANs connect several LANs along.

A local area network contains cables, access points, switches, routers, and different parts that change devices to attach to internal servers, net servers, and different LANs via wide space networks. the increase of virtualization has additionally oxyacetylene the event of virtual LANs, that change network directors to logically cluster network nodes and partition their networks while not a desire for major infrastructure changes.

For example, in AN workplace with multiple departments, like accounting, IT support, and administration, every department's computers may well be logically connected to a similar switch however segmental to behave as if they're separate.

What square measures the advantages of a LAN?
The advantages of a {lan|local square measure network|LAN|computer network} are similar to those for any cluster of devices networked along. The devices will use one web affiliation, share files, print to shared printers, and be accessed and even controlled by each other.

While the advantages of getting devices connected to a network have forever been well understood, it wasn't till the wide preparation of Wi-Fi technology that LANs became commonplace in nearly every kind of atmosphere. Today, not solely do businesses and faculties use LANs, however additionally restaurants, occasional retailers, stores, and homes.

Wireless property has additionally greatly distended the kinds of devices that may be connected to a local area network. Now, nearly everything thinkable may be "connected," from PCs, printers, and phones to sensible TVs, stereos, speakers, lighting, thermostats, window shades, door locks, security cameras--and even coffeemakers, refrigerators, and toys.

PAN (Personal space Network)
A personal space network (PAN) connects electronic devices at intervals in a user's immediate space. the dimensions of a PAN range from many centimeters to many meters. one of the foremost common real-world samples of a PAN is that the affiliation between a Bluetooth earphone and a smartphone. PANs may also connect laptops, tablets, printers, keyboards, and different computerized devices.

PAN network connections will either be wired or wireless. Wired affiliation strategies embrace USB and FireWire; wireless affiliation strategies embrace Bluetooth (the most common), WiFi, IrDA, and Zigbee. whereas devices at intervals a PAN will exchange knowledge with one another, PANs usually don't embrace a router and so don't hook up with the net directly. a tool at intervals a PAN, however, may be connected to a space area network (LAN) that then connects to the net. for example, a personal computer, a wireless mouse, and wireless headphones will all be connected to every different, however solely the pc will connect to the net.

What square measures the advantages of a PAN?
In PAN kind of network, there's no would like for further wires. Therefore, users do not ought to worry regarding cable management and floor area. For establishing an affiliation between 2 devices there ought to be solely Bluetooth enabled. Thus, PAN is taken into account to be extremely price-effective.

Using Personal Space Network, you'll be able to connect several of the devices to 1 single device at a similar time. For example, one mobile may be wont to connect several peripherals like keyboard, mouse, and printers or perhaps another mobile so files may be shared handily.

PAN networks may be forever ensured reliable and stable whenever the affiliation is established ten meters vary.

PAN networks square measure thought-about to be safe and secure over the other network since all the devices and knowledge square measure licensed. Hence, it's virtually not possible to hack or cause interference to devices here.

MAN (Metropolitan space Network)
A metropolitan space network (MAN) is comparable to a local area network (LAN) however spans a whole town or field, or another municipal or structure territory. MAN's square measure is shaped by connecting multiple LANs. Thus, MAN's square measure larger than LANs however smaller than wide-area networks (WAN) that cowl spread geographical areas, generally directly connecting users around the world.

MAN's square measure is generally very economical and may offer quick communication via high-speed carriers, like fiber optic cables. the increase of wireless and consecutive networking technologies, though, suggests that a proliferation of modalities for obtaining signals around a bigger MAN space.

What square measures the advantages of a MAN?
High Speed compared to WAN as MAN uses fiber optics, the info speed will reach a thousand Mbps quickly. The transfer rates for files and databases square measure quick.
Internet sharing Users will share their net association by putting in MANs. This helps many folks to access an equivalent high-speed net.

Not terribly pricey Connecting MAN to the WAN network is a smaller amount expensive. MAN provides robust knowledge potency. All MAN knowledge is centrally managed simply.

WAN (Wide Space Network)
A wide space network (WAN) could be a giant electronic network that connects teams of computers over giant distances. WANs square measure typically utilized by giant businesses to attach their workplace networks; every workplace generally has its own native space network or computer network, and these LANs square measure connected via a WAN. These long connections could also be shaped in many other ways, as well as chartered lines, VPNs, or science tunnels (see below).

The definition of what constitutes a WAN is fairly broad. Technically, any giant network that spreads out over a good geographical region could be a WAN. the web itself is taken into account WAN.

What square measures the advantages of a WAN?
The software system files square measure shared among all the users. Therefore, all can have access to the most recent files. This avoids the utilization of previous versions by them.

Organizations will kind their world integrated network through WAN. Moreover, it supports world markets and world businesses.
The emergence of IoT (Internet of Things) and advanced wireless technologies like computer networks or LAN-Advanced have created it simple for the expansion of WAN-based devices. Messages are sent terribly quickly across the world with the assistance of applications like WhatsApp, Facebook traveler, etc.
