computer and network technician jobs

Computer network support experts, also called technical support experts, analyze, troubleshoot, and evaluate computer network problems. They play an important role in routinely maintaining their organization’s networks, for example, in performing file backups on the network. Maintenance can be performed daily, weekly, or monthly and is important to the disaster recovery organization’s efforts. Addressing the information technology (IT) problem immediately is important because organizations depend on their network systems. Network support professionals can help computer users by phone, email, or in-person visits. They often work with network and computer system administrators who perform more complex tasks.

 

Computer support professionals typically do the following:

computer and network technician jobs

Pay attention to the descriptions of the client's computer problems

Ask customers questions to properly diagnose the problem

Walk customers through the recommended troubleshooting steps

Set up or repair computer equipment and related devices

Train users to work with new computer hardware or software such as printers, word processing software, and email

Share information with other team members and leaders about what causes the most problems for customers and other concerns that customers have.

Computer support professionals, also called customer support technicians, typically provide technical assistance to non-IT computer users. They respond to requests for help by phone and email. They can usually help users remotely, but they can also visit a website to solve the problem in person.

 

Help desk technicians can solve a range of problems that vary by industry and individual company. Some technicians work for large software companies or support companies and need to instruct business customers on how to use specific business programs, such as an electronic medical record program used in hospitals or medical offices. Sometimes they work with other techniques to solve problems.

 

Other help desk technicians work in call centers and answer simpler questions from non-business customers. Customers can be guided through the basic steps of reconnecting to the Internet or troubleshooting household IT products such as Wi-Fi routers.

Why is the LAN connection not working?

The cable connection should be easy to open-and-play, but often not. If you have Wi-Fi enabled, but your cable Ethernet connection is not working, you need to turn it off first. Wi-Fi. ... Right-click the icon, go to the Open Network and Internet Sites, then turn off the Wi-Fi tab.

 

how to make lan network wireless

If you have a "desktop" computer at home, you can connect it directly to a wireless router via a standard Ethernet cable. This is actually a popular way to start, because your pre-network setup probably involves a single computer connected to the Internet via a network cable and modem. It also gives you a simple, central place to install printers, scanners, etc. Which can be accessed by your wireless computers. Most wireless routers also have multiple wired connectors. This allows you to connect your computer / laptop to the router via standard CAT5E Ethernet cables. Some routers require configuration to start at least one wired computer, but when you are done, you can turn off and move the computer, leaving the router and modem where they are.

An example of a wireless network

If you do not want to connect any computer with cables to the router, you will need to decide where your wireless router will be in your home. A typical wireless router can communicate with computers within a radius of 200-300 feet, depending on obstacles. When you move away from the access point, the connection will be slower. Walls and other obstacles, especially concrete, further limit the wireless range. Therefore, it is best to place the access point centrally in your home. The closer the computer is to the router, the stronger the signal will be. In some homes, you may also be limited by the location of the telephone / cable lines, which may determine where you place the router.

Whether you are moving to a new home or simply improving your internet connection, building a strong home network can be difficult. However, you do not need to connect your devices to the Internet and protect your personal information. From where to turn on your router to how you can encrypt your Wi-Fi, here are eight expert tips for building a strong home network.

 

1. THERE IS A LAST ROUTER STRATEGY.

It can be a shame to overlook your router because the machines are ugly and bulky, but a strong home network relies on a router that is in good condition. IT experts recommend that you place your router as close to the center of your home as possible, away from walls. In addition to ensuring that your router's signal reaches all parts of your home, a properly placed router will reduce signal interference from devices such as microwaves and cordless phones. Placing your router in a central location will also reduce the risk of the Wi-Fi signal reaching outside your home and leaving your network vulnerable.

2. CHANGE YOUR NECESSARY NETWORK AND PASSWORD ROUTER.

The new routers come with a service kit identifier (SSID) name and password. Even if you need to use this basic information when you connect your computer to the Internet for the first time, security experts strongly recommend that you change it immediately. If you continue to use the default SSID and password, hackers can easily measure them (based on your router's manufacturer) and gain access to your router. Choose a name for your Wi-Fi network that does not share your personal information, such as your full name or address. To keep your Wi-Fi network secure, choose a strong password and change it every two months.

how to setup lan connection between two computers

 

The standard method of connecting two computers involves establishing a separate connection by connecting a cable to both systems. You may need interchangeable Ethernet cables, non-modem cables, or some parallel remote cables, or USB cables for a specific purpose.

 

ETHERNET RELATIONSHIP

Ethernet mode is a preferred option because it supports the required reliable configuration, high speed and minimum. In addition, Ethernet technology provides the most objective solution so that networks with more than two computers can be built later.

 

If one of your computers has an Ethernet adapter and the other has a USB cable, an Ethernet exchange cable can be used when you connect the unit from the computer to the first USB port.

SERIAL AND PARALLEL RELATIONSHIPS

This type of cable, called a wired connection in Microsoft Windows, offers lower performance but is similar to basic features like Ethernet cables. If you prefer this option if you have easily accessible Ethernet cables and the network speed is not worrisome. Parallel series and cables have never been used to connect more than two computers.

 

USB CONNECTION

New cables with normal USB 2.0 or type A connectors can be connected directly to both computers. You can choose this option, among others, if your computer does not have an active Ethernet network adapter.

What is a LAN?

 

LAN stands for local area network. A LAN is a group of computers and devices that are in a specific location. Devices connect to the LAN with an Ethernet cable or via Wi-Fi. Your home may have a LAN. If your computer, tablet, smart TV, and printer are connected wirelessly over Wi-Fi, these connected devices are part of your LAN. Only your devices have access to your LAN.

 

 

Some history on LAN

LANs were first used by colleges and universities in the 1960s. These computer networks were used to catalog library collections, record classes, record student grades, and share equipment resources.

 

Business groups did not like LANs until Xerox developed PARC Ethernet in 1976. The first commercial use of this new technology was Chase Manhattan Bank in New York City. In the early 1980s, many companies had an Internet network (intranet) with hundreds of computers sharing printers and storing files in one place.

After the release of Ethernet, companies such as Novell and Microsoft developed software products to manage these Ethernet LANs. Over time, these network devices became part of popular computer operating systems. Microsoft Windows 10 has tools for setting up a home network.

 

LAN functions

LAN is available in many sizes. A LAN is a group of devices connected through a home Internet connection. Small businesses have local area networks that connect a dozen computers to printers and file storage. Most LANs are managed by a server that stores files, shares data between devices, and routes them to printers and scanners.

local network computer sharing setup

Network Search allows Windows 10 to search for computers and other devices on the network. This feature turns on automatically when you are connected to private networks, such as those at home or at work. Network detection is turned off when you are connected to public networks that you should not trust and if you do not allow your computer to access those networks.

Enable network search

If your computer or Windows 10 device does not see other computers on the network, there are probably two culprits: either you provided the wrong network profile (public or private), or network discovery was disabled for some reason.

 

File and printer sharing

When connected to private networks, Windows 10 automatically turns on the printer and file sharing setting. This way, you can easily share folders, files, and printers with other computers and devices on your network. However, if your network administrator changes this setting, you may need to turn it on or off manually, depending on your needs.

how to create a lan network in windows 7

To set up a small network, you need a router and modem and how to connect them. Every computer also needs an adapter. An adapter is a device that allows a computer to communicate with a router. Almost all computers sold today have built-in Ethernet (wired) interfaces. Ethernet cables look like oversized phones. Most laptops today have built-in wireless interfaces.

Don’t worry, you don’t have to choose one type of network over another, wireless or wireless. Most networks use a combination of both. In fact, most wireless routers also have places where you can connect Ethernet cables, so it’s not uncommon for the main home computer to be connected directly to the router via a wire, and all other computers connected via Wi-Fi.

 

A standard network can look like this: A modem is connected to a telephone line or cable to provide Internet access. It is then connected directly to the router with an Ethernet cable. The router is then connected directly to one computer and at the same time sends a radio signal with which all other computers in the house can communicate with a Wi-Fi interface.

 

Now that all the computers are connected, you need to configure them with Windows to be able to communicate with each other. But don't worry. As I said at the beginning of this article, Windows 7 makes this process incredibly easy.

Area network

A area network (LAN) is a network limited to a relatively small area. It is usually limited to a geographic area, such as a writing lab, school, or building.

 

Computers connected to a network are generally classified as servers or workstations. Servers are not typically used directly by humans, but operate continuously to provide “services” to other computers (and human users) on the network. Included services can include printing and faxing, software hosting, file storage and sharing, messaging, data storage and discovery, full access control (security) to network resources, and much more.

what is networking give some relevant examples

Workstations are usually named so that they have a human user who communicates with the network through them. Workstations were meant to be a desktop consisting of a computer, keyboard, screen, and mouse or laptop, with a built-in keyboard, screen, and touchpad. With the advent of the tablet and touch screen devices such as the iPad and iPhone, our definition of a workstation is evolving rapidly and includes these devices because of the potential between working with a network and using network services.

 

Participants are usually stronger than workstations, although arrangements are based on needs. For example, a group of servers may be located in a secure location, away from people, and only accessible over a network. In such cases, it would be normal for the servers to run without a dedicated display or keyboard. However, the size and speed of server processors, hardware configuration, and kernel memory can greatly increase system costs. On the other hand, a workstation may not need as much storage space or working memory, but it may also require an expensive screen to suit the user’s needs. All computers on the network must be properly designed for use.

On a single LAN, computers and servers may be connected by cables or wirelessly. Wireless access to a wired network is made possible by wireless access points (WAPs). These WAP devices provide a bridge between computers and networks. A typical WAP might have the theoretical capacity to connect hundreds or even thousands of wireless users to a network, although practical capacity might be far less.

Each of those arrangements is a different network topology, and each topology has its advantages and disadvantages.

Imagine the journey of a piece of data through one of those larger networks. What path will it take? When there are multiple paths, how does it know which path is best?

Once networks become larger, routing strategies become more important. There isn't a big difference between two stops and three stops in a path, but there is a big difference between 20 stops and 300 stops.

Types of networks

We use different terms to refer to networks based on their size and characteristics. Let's touch on a few of them here.

The most common type of network is the Local area network (LAN), a network that covers a limited area like a house or school.
