how to connect computer to lan network

TCP / IP is the set of protocols used by the Internet and most LANs worldwide. In TCP / IP, each host (computer or other communication device) connected to the network has a unique IP address. An IP address consists of four octaves (numbers in the range 0 to 255) separated by decimal points. The IP address is used to uniquely identify a host or computer on the LAN. For example, a computer with the hostname Morpheus may have an IP address of 192.168.7.127. You should avoid giving the same IP address to two or more computers by using the range of IP addresses reserved for local private networks; this range of IP addresses typically begins with the eighties 192.168.

how to connect computer to lan network

LAN network address The first three octaves of an IP address should be the same for all computers in the LAN. For example, if a single LAN has a total of 128 hosts, the IP addresses could be assigned starting with 192.168.1. x, where x is a number in the range 1 to 128. You could create coherent LANs within the same company in the same way as up to 128 other computers. Of course, you are not limited to 128 computers, as there are other ranges of IP addresses that allow you to build larger networks.

 

There are different classes of networks that determine the size and unique unique IP addresses of any possible LAN. For example, a class A LAN can have over 16 million unique IP addresses. A class B LAN can have over 65,000 unique IP addresses. The size of your LAN depends on the range of reserved addresses you use and the subnet mask (explained later in the article) associated with that range (see Table 1.).

Most ISPs offer a number of service plans at different prices. Signing up for a provider’s basic plan can save you a few dollars a month, but it costs a lot more in terms of time and convenience. Even a slight increase in data transfer rate can shave precious minutes off long downloads or allow full Netflix movies to be streamed without annoying errors.

small home network setup

Do the following:

 

Learn about the high-speed Internet services available in the area. Ask for recommendations from neighbors, search DSLReports.com, and see ads from new providers that open up your business. Of the many home Internet connections, fiber is particularly desirable.

Update your internet service plan to the best available and change providers if necessary. The best home Internet service is not necessarily rated the highest Mbps (highest bandwidth). Network latency (also known as ping) for Internet connections is equal, if not greater, to the response. Network reliability — services with minimal downtime or sudden significant performance degradation — is also essential.

Sign up for business class internet service if available. In return for a higher price, business Internet customers get better technical support and more design options, such as higher upload speeds. These plans generally do not prescribe bandwidth control or limitation.

ip configuration for lan network

Switch vs. hub

Hubs can also connect multiple devices to share resources, and a collection of devices that connect to a hub is called a LAN collection.

 

Hubs are different in that packets sent from one of the connected devices are broadcast to all devices connected to the hub. With this version, packets are only routed to the port that brings them to the machine that sent the packets.

 

The switch usually connects a LAN segment, so the hub can connect. The switch filters potential traffic for devices in the same LAN area. Because of this information, exchanges can use their own processing facilities more efficiently as well as network bandwidth.

Switch vs. router

Switches are sometimes confused with routers, which are also offered to forward and direct network traffic, hence the name. But they serve a different purpose and place.

 

Routers can be used at Layer 3 - the network level - and are used to connect networks to other networks.

 

An easy way to think about the difference between a switch and a router is to think about a LAN and a WAN. Devices connect locally through switches, and networks connect to other networks through routers. If you’re thinking of a common route, working with packages to access the Internet - such as: device> hub> converter> router> internet - it should also help.

Types of network software in computer networks

1. Personal area network (PAN)

It is used primarily in the home environment and connects one or more computers, printers, phones, and other personal devices via a modem in wired or wireless mode.

It is used for sharing documents and photos in nodes, internet access and entertainment.

2. Local area network (LAN)

LAN connects computers and other equipment in rooms or buildings and allows local users to share information through file servers, print documents through centralized printers, perform transactions through central servers, and securely through a firewall router.

Computers and devices are connected through nodes, switches, network interfaces, cables, and optical fibers. In a modern LAN, computers are connected wirelessly via access points (antennas) and allow flexible seating arrangements and freedom for millennials to work from anywhere in the office.

LAN provides a high-speed network, optimizes the use of software licenses, and saves costs by connecting entire users over a single Internet connection and efficiently sharing resources.

LANs can be logically divided into multiple virtual local area networks (VLANs) and connected through a router. Each VLAN will have its own characteristics, and access may be restricted to users via a VLAN.

Advantages of computer network

What is a network?

A computer network is a device (often called a network) that connects to a communication network. The mouth can be a computer, printer or other device that can send or receive data from another mouth / device over a network.

Security

As data is transmitted orally through the network to the final destination, it can be damaged or stolen at that time, so information retention is very important.
