Lan Write For Us – 1. What do I want to use or have a LAN for?
Share(have) internet and a single printer for all the nodes(computers).
You must use external storage devices to do anything, like moving files back and forth. Some of you may spend more time waiting than you should. On the other hand, you’re passing a USB from one computer to another every time you want to do something, makings everything goes slower.
2. What type of network do I need? Lan Write For Us
LAN network (via wired or wireless).
Safe. Based on its topology and scope.
One of the most critical events for networking is the appearance and rapid spread of the local area network (LAN) to standardize connections between machines used as office systems. As its name indicates, it is a way of interconnecting a series of computer equipment. At its basic level, a LAN is a shared medium (like a coaxial cable to which all computers and printers are connected), along with a set of rules governing access to that medium. The most widely used LAN, Ethernet, uses a mechanism known as CSMA/CD.
The most recommended topology is:
Star: The star topology where the nodes are connected to a hub. We are talking about a device that receives the data signals from all the equipment and transmits them through the different ports.
The repeater allows us to easily add equipment. It has the advantage that when a cable breaks, only one computer is isolated from the network, and repair is more accessible. The only disadvantage is the cost (it requires a line for each computer + the hub) and the possibility of the corner failing.
Maya: All nodes are interconnected with each other. In this way, the data can be transmitted in multiple ways, so the risk of breaking one of the cables does not threaten the operation of the network. Nor does it require a hub or central node, and the risk of interruptions and interference is avoided.
3. Where will a LAN network install?
- Count the number of computers you want to connect via cable. When you set up a LAN, you first need to know how many computers will be connected to the network via Ethernet cables. This will determine the number of ports you will need.
- You only need a router if you want to connect four or fewer computers by cable. If you have more than four, you will probably need to get a switch to extend the number of ports available on the router.
- Decide if you want to create a wireless network. Most routers available in stores or online come with wireless network capabilities. If you allow some devices to connect wirelessly, you will need a router to transmit a wireless network signal.
- You cannot connect wireless devices through switches. Switches can only be used in local wired networks or to extend the number of ports available on the router.
- Decide if you want all devices on the network to have Internet access. You can just use the network switch if you don’t need the machines to have an Internet connection. You’ll need a router to handle the links if you wish all connected devices had Internet access.
- Measure the distances between all wired devices. This is not a problem in most home installations, but network cables cannot extend beyond 100 m (328 ft). You must install switches in between if you have to run a line that extends beyond that distance.
- Keep in mind the needs you will have in the future. If you occupy all the hardware ports, ensure that the configuration allows other devices to add later.
4. What devices will I need? Lan Write For Us
To extend the signal or wireless coverage in a LAN Network, there are a lot of different devices that I will explain in several Telepieza blog posts because it is pervasive.
The devices are Internal and External Antennas, Access Points, Extension Points, Wireless Bridges, Wireless Switches, and Wireless Switch Routers.
Below, we will explain the two most used wireless devices in home networks: the Access Point and the Extension Point.
An Access Point is connected by an Ethernet card to the LAN and RJ45 cable to a Switch or Hub or Router Switch without WLAN.
The Access Point or Access Point covers a large wireless area between Computers with Wireless devices, performing the signal receiver and transmitter function between the wireless NETWORK and the strengthened NETWORK.
We cannot confuse an Access Point with a Wireless Signal Extension Point and, simultaneously, with a WLAN Router; they are totally different devices and, in physical appearance, the same.
Its most important functions are:
- Extend the wireless distance between the wireless Client PCs and the signal receiver or Access point.
- If our router does not have WLAN, the Access Point supplies this function.
- It is an excellent wireless network traffic manager between the wireless terminals closest to the Access Point.
- They can simultaneously manage and control many Client computers at the same time, being able to reach up to 50 simultaneous devices.
- The range is about 150 meters in open areas; in large regions (+ than 150 meters), more Access Points or Extension Points are needed to cover all the wireless Computers in the LAN Network.
WIRELESS EXTENSION POINT Lan Write For Us
Extension Points (EPs) extend the wireless network range by retransmitting signals from a Computer, Access Point or to another extension point. Extension points do not connect to the Ethernet network.
The purpose of Extension points is to chain to pass data between an Access Point, Extension Point and distant Computers so that a bridge is built between them.
The meters these devices cover depend on the obstacles (Buildings, Walls, Doors) to overcome, but the usual thing is 100 meters indoors and 300 meters outdoors.
The Extension points have an Ethernet card incorporated to be configured via Browser. Still, it is unnecessary to be connected to the wireless network when it is already configured and working.
In-home networks, the solution to cover areas with a low signal is the Extension points to extend all the coverage of the wireless network between our computers and the wireless router. We will explain two wireless network environments with example images to see more clearly the above.
The router does not have a WLAN or wireless network; we add an Access Point to our LAN network through a switch port of the router. But one of the laptops is more than 200 meters away from the access point; an Extension Point has been placed to cover that distance, and that way, all our wireless devices can go out through the router’s LAN to the Internet.
The router has a wireless or WLAN connection, but one of the laptops is more than 200 meters away from the router; to cover that distance, an Extension Point has been placed, and in this way, all our wireless devices can go out to the Internet through the router’s WLAN.
It is a device that converts digital signals into analogue (modulation) and vice versa (demodulation), thus allowing communication between computers through the telephone line or cable modem. It sends the modulating signal through another signal called a carrier.
The modulator emits a signal called a carrier. Generally, this is a simple sinusoidal electrical signal of much higher frequency than the modulating signal. The modulating movement constitutes the information prepared for transmission (a modem prepares the information but does not carry out the message). The modulator modifies some characteristics of the carrier (which the action of modulating) so that a signal obtained, including the modulator’s information. Thus the demodulator can recover the original modulating password, removing the carrier.
In telecommunications, the term repeater has the following standard meanings:
- An equivalent device that amplifies an input signal, regardless of its countryside (analogue or digital).
- A digital device that amplifies, shapes, retimes or performs a combination of any of these functions on a digital input signal for retransmission.
In the case of digital signals, the repeater often called a regenerator because, in fact, the output signal is a “regenerated signal” from the input signal.
A wifi repeater, also called a wifi amplifier, complies with the functional characteristics of a repeater. Hence, it collects the signal and amplifies it to extend the range of the movement.
These devices are peculiar because they intended to propagate the Wi-Fi signal received from a transmitter, usually a wireless router.
Its use extends to open and closed spaces, such as homes or offices.
A computer network is a device that interconnects wireless communication equipment to form a network that connects mobile devices or wireless network cards.
They are devices configured in wireless-type networks that are intermediaries between a computer and a network (Internet or local). They make it easy to connect several client machines without the need for a cable (greater portability of the equipment) and for them to have a connection without limiting their bandwidth.
A switch or switch an interconnection device used to connect network equipment forming what known as a local area network (LAN) whose technical specifications follow the standard known as Ethernet (or technically IEEE 802.3).
Interconnection devices have two areas of action in telematic networks. At the first level the best known, the routers, which are responsible for the interconnection of networks. On a second level would be the switches, which are responsible for the interconnection of equipment within the same network or what amounts to the same thing; they are the devices that, together with the cabling, constitute the local area networks or LAN.
A concentrator (hub) is a device that allows centralizing the cabling of a computer network to expand it later.
It works on the physical layer (layer 1) of the OSI model or the media access layer of the TCP/IP model. This means that the device receives a signal and repeats it by emitting it through its ports (repeater).
Currently, the task of hubs often performed by switches.
Network bridge (in English: bridge) is the interconnection device of computer networks that operate at layer 2 (data link layer) of the OSI model.
It interconnects network segments (or divides a network into parts) by transferring data from one network to another based on the physical destination address of each packet.
In short, a bridge connects network segments forming a single subnet (allows connection between computers without the need for routers). It works through a table of MAC addresses detected on each piece to which it connected. When it detects that a node from one of the segments is trying to transmit data to a node from the other, the bridge copies the frame to the different subnet, having the ability to discard the frame (filtering) if it does not have that subnet as a destination.
The router or router is a device that operates in layer three of level 3. Thus, it allows several networks or computers to connect with each other and, for example, share the same Internet connection.
A router uses a routing protocol, which allows it to communicate with other routers and share information to find the fastest and most appropriate route to send data.
A typical router works in a control plane (in this plane, the device obtains information about the most effective output for a specific data packet) and in a forwarding plane (in this plane, the device is responsible for sending the data packet received to another interface).
A gateway is a device that allows interconnecting networks with different protocols and architectures at all levels of communication. Its purpose is to translate information from the protocol used in a network to the protocol used in the destination network.
A gateway or gateway usually a computer configured to enable the machines on a local network (LAN) connected to it to access an external network, generally performing IP address translation operations (NAT: Network Address Translation). This address translation capability makes it possible to apply a technique called IP Masquerading (IP masking), which often used to provide Internet access to computers on a local area network by sharing a single Internet connection and, therefore, a single external IP address.
A bridge router or brouter is a computer network interconnection device that functions as a network bridge and router. A brouter can configure as a network bridge for part of the network traffic and a router for the rest.
It is a connector that helps to transfer information between networks, simultaneously combines the functions of bridge and router, and chooses “the best solution of the two”.
Brouters work as a router with routable protocols and as a bridge with those that are not. They treat these functions independently and provide hardware support for both.
A router can first check if the network supports the protocol used by the packet it receives, and if it doesn’t, instead of dropping the box, it forwards it using physical address information.
