RE: LAN vs WAN Karly Derosena 2/22/2022 9:32:02 AM
a) LAN : (local area network) is a group of computers and network devices connected together,
usually within the same
building. By definition, the connections must be high speed and relatively inexpensive (e.g., token
ring or Ethernet).
WAN : (wide area network), is not restricted to a geographical location, although it might be confined
within the bounds
of a state or country. A WAN connects several LANs, and may be limited to an enterprise (a
corporation or an organization) or accessible to the public. The technology is high speed and
relatively expensive.
The Internet is an example of a worldwide public WAN.
The classroom network is example of local area network LAN.

The Marketing departments of companies these days are involved in the development of
corporate WEB Sites because of the tremendous reach that a WEB Site can have in the
marketplace. As such, Bob Jones’ department should be consulted and have
representation in the WEB Site development process. The image projected by the quality
of the WEB Site will be a critical factor to its success.

Local area networks can, of course, only operate locally in small areas such as office buildings or even just
one floor of a building. They're not regulated by the FCC, are cheaper than WANs, and also much easier to
set up. Their speed is also greater on the whole.

WANs (wide area networks) cover a much larger area and connect larger companies with branches pretty
much anywhere. With this, you can have a very intricate and large network. However, also with this
comes a much larger cost and often slower speeds than the LAN network.

RE: LAN vs WAN Eric Frazier 2/22/2022 1:40:12 PM
The while both LAN and WAN are area networks, they have a few differences. LAN is a local area network.
This network refers to a location like a building or campus. It's generally small geographically. Most LANs
can be represented with network devices. They tend to be demarcated by a firewall and usually only have
one or two ways to get to the WAN network. A WAN is a wide area network. This tends to be bigger than
a LAN. A WAN can represent a city wide network all the way up to a the world network itself. LANs can
make up WANs but the reverse is not true. Telecommunication companies tend to deal with the WAN.
Where companies tend to deal with their own networks.

LAN is a local area network where all the computers are in the same general location such as
office or building or a group of nearby buildings where computers are usually connected by a
single cable or a local Wi-Fi connection.
WAN which is also known as a wide area network and it is the one that covers a much bigger
region than a local are network, which could be across a town, region, country or the entire
world. A WAN uses an external cabling such as a phone network or a cable company's fiber optic.
Unlike LAN, a WAN is usually owned by a different organization to the people, and to the people
and organizations that use the network to send and receive data. A Wan will have slower data
transfer speeds than a LAN.

A local area network is a network of computers usually within the same geographical location such as an
office building, a college campus, a hospital etc. These computers are usually connected together by
Ethernet cables but could also have wireless connections. A wide area network is a connection of LAN’s
that covers a larger geographical region. For Example branches of offices in different towns. a country.
LAN’s could be wired or wireless whilst WANs usually use external cabling or fiber optics. LAN data speeds
are faster because of its proximity whilst WAN data speed transmission are slower. Data transfer
technology for a LAN is different from a WAN.

RE: LAN vs WAN Taylor Keltz 2/29/2022 2:13:02 AM
Local Area Network (LAN) is a group of computers located in the same area. It is generally a clearly
defined small area from one floor to a group of buildings. The example in the book uses McClellan Air Force
Base, and I will concur that my Air Force Base in Ohio is also a grouping of buildings that the LAN covers.
LANs are connected to the backbone network, which connects several other networks. In my case in the
Air Force, our backbone network is the network for the entire Air Force, in which the Air Force Bases are
connected.
Wide Area Network (WAN) connect backbone networks and Metropolitan Area networks. This isn't usually
built by an organization themselves, but use leased circuits from larger internet service providers.

A LAN or Local Area Network is a groups computers together in a small area. The area could be a floor in a
building, the entire building itself or the building and the surrounding areas. The LAN has a defined coverage
area and is way smaller than a WAN, Wide Area Networks. A LAN is usually supported by the company that
is employing it. In contrast, the WAN is usually supported by another company. This is because a WAN
covers a large area and most companies lease the circuits for this coverage. Common companies that
provide WAN are Sprint or AT&T.

RE: LAN vs WAN Elh Ibrahima Barry 2/29/2022 12:53:53 PM
LAN - A local area network (LAN) is a computer network covering a local area, like a home, office, or group
of buildings located close to each other. Current LANs are most likely to be based on switched IEEE 202.3
Ethernet, or Wi-Fi technology running at 10, 100 or 1000 Mbps.
Generally, a local area network consists of local proximity devices to each other and has limitations of
finite distance. The LAN can be either wired or wireless, but only in one place.
WAN - A wide area network or WAN is a computer network covering a wide geographic area, in contrast
with personal area networks (PAN), metropolitan area networks (MANs) or local area networks (LANs)
which are usually limited to a room, building or campus. The most important example and best known of
a WAN is the Internet.
A wide area network (WAN) consists of several LANs connected with each other over long distances. An
example would be a corporate office connected to each of its satellite offices.

The territorial structure of any region corresponds to a network of
all its economic interactions. The implementation of networks, however,
is rarely premeditated but the consequence of continuous improvements
as opportunities arise, investments are made and as conditions change.
The setting of networks is the outcome of various strategies, such as
providing access and mobility to a region, reinforcing a specific trade
corridor or technological developments making a specific mode and its
network more advantageous over others. A transport network denotes
either a permanent track (e.g. roads, rail and canals) or a scheduled
service (e.g. airline, public transit, train). It can be extended to cover
various types of links between points along which movements can take
place. The relevance of a network is related to its connectivity.

LAN have a small geographical range and do not need any leased
telecommunication lines. WAN have a large geographical range generally
spreading across boundaries and need leased telecommunication lines. Lan
has a high bandwidth is available for transmission however WAN low
bandwidth is available for transmission. Having all the computers in a LAN
physically connected to a router is the fastest way to transfer data between
computers on a LAN. WAN speeds are affected by a number of factors. The
equipment used in LANs that are connected to WANs affects a user's
experience, as does the type of cabling used in the wide area network itself.
WANs are typically slower than LANs due to the distance data must travel. The
most secure computer is one that is not connected to any network. LANs are
safer than WANs, just by the nature and scope of a wide area network.

I read what most of the classmates have said and I just want to add security.
The larger the area a network covers, the more risk it takes when dealing with
security questions. LANs are smaller by design and so a smaller geographical
area needs security nonetheless, but in a smaller scale compared to the area a
WAN covers. Security is of great concern as WANs will access data across a
whole country or, at least, a state.
