What is a Computer Network, Network, LAN, WAN, and Salary

Computer Network
Define the term Computer Network: Two or more computers are connected to transmit the data electronically. In addition to physically connecting computers and communication devices, a network system provides a consistent architecture that allows a variety of device types to transmit information in an almost seamless manner.
The primary network types are Local Area Networks (LANs) and Wide Area Networks (WANs). Local networks connect computers and peripherals in a limited physical area, such as an office, lab, or university campus, through connections (wires, Ethernet cables, fiber optics, Wi-Fi) that transmit data quickly. A typical LAN contains two or more high-capacity computers, printers, and large-capacity storage devices, known as file servers, that allow each computer on the network to access a standard set of files. With LAN operating system software that interprets inputs and directs networked devices, users can communicate with each other. Sharing printers and storage devices; and simultaneously access processors, data, or programs (instruction sets) located in the center. LAN users can also access other LANs or wide area networks. LANs with similar architectures are connected by "bridges" serving as transfer points. LANs of different structures are connected by "gateways" that convert data as they transfer among systems.
WANs connect computers and lesser networks to more extensive networks in larger geographic areas, including various continents. You can connect computers to cables, fiber, or satellites, but their users typically access networks/systems through a modem (a device that computers can talk to over the phone line). The largest WAN is the Internet, a network of networks and bridges connecting billions of computer users on every continent.
What is a Network?
A network is made up of two or more computers connected to share resources (such as printers and CDs), share files, or provide electronic communication. Computers in a network can be connected by cables, phone lines, radio waves, satellites, or infrared light beams.
The two most common types of networks are:
Local Area Network (LAN)
Wide Area Network (WAN)
You can also see references to metropolitan area networks (MAN), wireless (WLAN), or wireless (WWAN) networks.
Local Area Network (LAN)
A LAN (local area network) is a network that is limited to a relatively small area. It is usually limited to a geographical area such as a writing lab, a school, or a building.
Computers connected to a network usually categorized as servers or workstations. Servers are typically not used directly by humans, but always work to provide services to other computers (and their users) on the network. Services provided include faxing and printing, software hosting, sharing files and saving, messaging, saving and recovering data, full access control (security) of network resources, and many more.
Workstations are referred to as such because they usually have a human user interacting with them through the network. Workstations have traditionally been considered desktop computers, consisting of a computer, a keyboard, a screen, and a mouse or a laptop with an integrated keyboard, display, and touchpad. With the advent of tablet and touchscreen devices like the iPad and the iPhone, our workstation definition is rapidly evolving to include these devices because they can interact with the network and use network services.
Servers are usually more potent than workstations, although configurations based on requirements. For example, a server group may be located in a secure area that is not close to people and accessible only through the network. In such cases, it is common for servers to operate without a dedicated screen or keyboard.
Nevertheless, the size and speed of the server's processors, hard drive, and main memory can significantly increase system costs. On the other hand, a workstation may not require as much memory, but an expensive display to meet the needs of the user. Each computer in a network must be configured to use it.
In a single LAN, computers and servers can be wired or connected wirelessly. Wireless access to a wired network provided by wireless access points (WAP). These WAP devices bridge the gap between computers and networks. A typical WAP has the theoretical capability to connect hundreds or even thousands of wireless customers to a system, although the practical capacity may be much lower.
The servers are almost always connected to the cable network because the cable connections remain the fastest. Stationary workstations (desktops) are typically also connected to the network via a cable, although the cost of wireless adapters has dropped so much that installing workstations in an existing installation with short cabling may be more comfortable and less expensive. Use Wi-Fi for a desktop.
For more information on configuring a LAN, see Topology, Cabling, and Hardware in this tutorial.
Wide Area Network
WANs (Wide Area Networks) connect networks in larger geographic areas such as Florida, the US, or around the world. Dedicated transoceanic cables or satellite uplinks can be used to connect this type of global network.
Using a comprehensive network, schools in Florida can communicate with places like Tokyo in seconds, without having to pay big phone bills. Two remote users from around the world who equipped with microphones and webcam workstations can make a real-time conference call. A WAN is complicated. It uses multiplexers, bridges, and routers to connect local and metro networks to global communication networks such as the Internet. For users, however, an extended network does not seem to be very different from a local network.
Salary
In the United States, the average computer network technician salary is $44,562, while an independent technician earns $20.07 per hour, according to PayScale.

Site surveys that improve your wireless network

1 - Overview of Predictive Sites
They are often understood; this type of pre deployment site survey offers cost and time efficiency and is very accurate. Using RF and specialized algorithms, site surveys will produce RF projections in your specific environment.
In our experience, this software is very accurate and gives you incredible insight into their environment. In combination with an experienced wireless service provider, a successful design can be achieved even in high-density areas. The key to a good predictive survey is to have as much information as possible. We recommend creating floor plans and blueprints.
2 - Survey on physical locations
This type of wire recommended for more complex wireless purposes. This usually affects applications from AP to AP and is often conceptually sensitive. For example, RTLS in hospitals, wireless video surveillance and multimedia over the air.
Typically, an on-site survey uses the projected results to compare them to the wireless design and create that design in the light of real-life interference or noise. It's important to simulate applications running on the network to make sure they are working correctly.
3 - passive
With these survey types, you can capture RF data from all access points in a specific area and review your design requirements. This feature allows you to save WiFi thermal maps, giving you a good overview of the extent of your coverage and the presence of holes at different levels.
Key design elements that passive validation can support include primary and secondary RSSI interference, noise, SNR, and co-channel interference.
4 - After validation
A wireless network design can be great on paper, but real success is that it does exactly what it needs to support. A site survey after validation will ensure that your new network meets the requirements you set at the beginning of your design.
Areas to consider include data rates, radio device ratios, jitter, latency and quality of service, high density and co-channel interference, and other RF characteristics.
You can even use an application performance test to test your network on the application side and get a single view of your network performance.
It is important to understand the different types of site studies. To find out when you need it and to make sure your next wireless network is working correctly. In this way, we are confident that your stress level will undoubtedly decrease.
The Definitive Checklist on Wireless Site Survey
1. Identify your wireless needs
Before running the actual survey on the site, it is essential to consider your wireless network needs. What is the desired speed and bandwidth? How many client devices will access the network simultaneously? What emission power will they have? These are all factors to consider before starting your investigation.
2. Get a floor plan
The next step is to get a diagram of the area covered by the network. Construction plans are perfect, but a fire evacuation diagrams can be used if it does not exist. On the floor plan, note the positions of walls, stairwells, elevators and other elements that could lump wireless signals.
3. Perform a detailed procedure
The ideas are useful, but they do not tell the whole story. You will need to complete a complete survey on the wireless coverage area, detecting all the crucial elements that are not included in the projects.
4. Evaluate the current infrastructure
Find locations where you can mount wireless access points, such as ceilings and pillars, and note the locations of existing wired network cabinets and existing access points.
5. Determine areas to cover
Where is it most important for users to have high bandwidth? Offices, meeting rooms, and meeting rooms are usually essential. Is good coverage needed even in corridors, bathrooms, stairwells and elevators? Do not forget the service areas that can accommodate wireless equipment. Indicate these areas on the map. Being strategic in the spaces to be covered, you will obtain a powerful and efficient network.
6. Decide temporary positions of the access point
Based on the considerations above, develop some initial ideas for the location of access points. Be sure to check the extent of coverage of your access points. Create overlaps between nearby access points to ensure seamless roaming, dynamic load balancing, and network resiliency.
7. Participate in a survey on the wireless site
Here are some options. You can install the wireless site detection software on a laptop or purchase a specialized survey tool. In any case, place your wireless access point in each of the temporary slots, then use the poll tool to collect data at different times. The software records the connected access point, the transmission rate, the power and the signal quality. The more complete the procedure, the more useful the survey will be.
8. Refine the locations of the access points
Based on the data you collect, play as you move access points to find the optimal places. Experimentation at this stage will pay off once the network installed.
9. Save the results
Once you have found the best locations for access points, save them on floor plans. Congratulations - your wireless network is now designed and ready for deployment. However, keep in mind that wireless polls should be done at regular intervals to maintain high performance. Radio environments can modify with new wireless devices or new furniture. The locations of the access points will need to be adjusted periodically.
As you can see, many steps lead to a successful survey on the wireless site. It is an important task, the result of which affects the daily performance of your network. That's why we recommend leaving this to the professionals. Turnkey technologies have vast experience in conducting wireless surveys for a wide range of businesses.
