what is a technician

What is a technician in IT ? IT support technicians provide assistance to computer users by answering questions, resolving technical problems and maintaining a company's network, software and computer equipment. They are also called desktop support technicians or computer support specialists.

The IT Support team maintains the computer networks of all types of organisations, providing technical support and ensuring the whole company runs smoothly. IT Support monitors and maintains the company computer systems, installs and configures hardware and software, and solves technical problems.

A technical support engineer (also known as an information technology support engineer) helps to solve technical issues. They might work to help a company deal with internal technical issues, or they might assist customers or clients with their external tech issues.

what is a support technician ? An IT support technician is responsible for helping customers and consumers understand how to use and fix their computers or other various technologies. You may receive complaint calls about malfunctioning equipment and have to diagnose the problem over the phone and help the customer solve the problem if possible. Technicians must be extremely knowledgeable about the equipment they are providing support for so as to best assist the customer

As a technical support/helpdesk employee, you’ll be monitoring and maintaining the computer systems and networks within an organisation in a technical support role. If there are any issues or changes required, such as forgotten passwords, viruses or email issues, you’ll be the first person employees will come to.

Most importantly, as businesses cannot afford to be without the whole system, or individual workstations, for more than the minimum time taken to repair or replace them, your technical support is vital to the ongoing operational efficiency of the company.

define computer network

A define computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server. The Internet itself can be considered a computer network.

• LAN(Local Area Network)
• PAN(Personal Area Network)
• MAN(Metropolitan Area Network)
• WAN(Wide Area Network)

A local-area network (LAN) is a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.

Two Types of Networks: LANs and WANs. Networks are divided into two types, a LAN (Local Area Network) or a WAN (Wide Area Network), which are generic terms referring to two important basic types of networks.

types of networking

There are mainly three types of networking based on their size

·         Local Area Network (LAN)

·         Metropolitan Area Network (MAN)

·         Wide area network (WAN)

LAN (Local Area Network)

A LAN is a computer network which spans over a small geographical area such as home, building, office, etc. In LAN, computers are placed relatively close. Since computers are located within small distance, they do not need special devices and cables to connect with each other.

MAN (Metropolitan area networks)

A MAN is a computer network which connects two or more LAN networks within same city. When due to distance connecting two LANs is not possible, MAN network is used. It is larger than LAN but smaller than WAN. It deploys special devices and cables to connect the LANs.

WAN (Wide Area Network)

WAN is a computer network which spans over a large geographical area such as state, region, country etc. WANs are typically used to connect two or more LANs or MANs which are located relatively very far from each other. To provide connectivity, this network uses special devices, cables and technologies.

Networking concept

Let’s know about basics of Networking concept. In the broadcast sense a

 network is any interconnected group of people or things capable of sharing meaningful information with one another. In a technology context, network is usually short for "computer network" or "data network" and implies that computers are the things sharing the meaningful information.

The network you have at home uses the same networking technologies, protocols and services that are used in large corporate networks and on the Internet. The only real difference between an home network and a large corporate network is the size. A home network will have between 1 and 20 devices and a corporate network will have many thousands.

Networks can be wired or wireless with most networks being a mixture of both. There are many different ways network nodes can be connected together. This isn’t normally a consideration in small networks but has networks get larger it becomes more important.

Common connection technologies like Wi-Fi, Bluetooth etc are designed to work using a particular network topology. When designing networks and choosing connection protocols having an understanding of these topologies is important.

Common are:

·         Bus

·         Ring

·         Mesh

·         Star

·         Hybrid

Each of these topologies has advantages and disadvantages this Network topologies article has a really good overview of each topology along with advantages and disadvantages.

Early Ethernet networks used a bus structure, modern Ethernet networks and Wifi networks. use a star bus (hybrid) structure.

local area network

A local area network (LAN) is a computer network covering a small local area, like a home, office, or small group of buildings such as a home, office, or college.

A local area network (LAN) is a system for linking private telecommunications equipment, as in a building or cluster of buildings.

Computer network covering a small local area, like a home, office, or small group of buildings such as a home, office, or college
A computer network covering a small geographic area, like a home, office, or group of buildings. The defining characteristics of LANs, in contrast to Wide Area Networks (WANs), include their much higher data transfer rates, smaller geographic range, and lack of a need for leased telecommunication lines 

• Storage Area Networks — Separate network handling storage needs — Detaches storage tasks from specific servers — Shared storage facility across high-speed network — Hard disks, tape libraries, CD arrays — Improved client-server storage access — Direct storage to storage communication for backup

• High speed office networks — Desktop image processing — High capacity local storage

• Backbone LANs — Interconnect low speed local LANs — Reliability — Capacity — Cost

define wan

How do you define WAN? A computer network that spans a relatively large geographical area. A WAN consists of two or more local-area networks (LANs). Computers connected to a wide-area network often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites.

Wide Area Network: Examples of WAN. Local area networks are connected to one another through a device called router. There may be used many router to connect large amount of LANs. The big example of wide area network is internet. On internet we transfer files from one computer to other.

The WAN port in a WiFi router is essentially connecting you to the real "internet". The cable coming out of modem, or if a PPPoE connection, a simple RJ45 ethernet cable are to be plugged in the WAN port. The WAN cable transmits the data from Internet to "Subnet" created by your router.

what is network

What is network? To make a network, you need nodes and connections (sometimes called links) between them. Linking up the nodes means making some sort of a temporary or permanent connection between them. In the last decade or so, wireless connections have become one of the most popular ways of doing this, especially in homes. In offices, wired connections are still more commonplace—not least because they are generally faster and more secure and because many newer offices have network cabling already in place.

Apart from computers, peripherals, and the connections between them, what else do you need? Each node on a network needs a special circuit known as a network card (or, more formally, a network interface card or NIC) to tell it how to interact with the network. Most new computers have network cards built in as standard. If you have an older computer or laptop, you may have to fit a separate plug-in circuit board (or, in a laptop, add a PCMCIA card) to make your machine talk to a network. Each network card has its own separate numeric identifier, known as a MAC (media access control) code or LAN MAC address. A MAC code is a bit like a phone number: any machine on the network can communicate with another one by sending a message quoting its MAC code. In a similar way, MAC codes can be used to control which machines on a network can access files and other shared resources. For example, I've set up my wireless link to the Internet so that only two MAC codes can ever gain access to it (restricting access to the network cards built into my two computers). That helps to stop other people in nearby buildings (or in the street) hacking into my connection or using it by mistake.

The bigger you make a network, the more extra parts you need to add to make it function efficiently. Signals can travel only so far down cables or over wireless links so, if you want to make a big network, you have to add in devices called repeaters—effectively signal boosters. You might also need bridges, switches, and routers—devices that help to link together networks (or the parts of networks, which are known as segments), regulate the traffic between them, and forward traffic from one part of a network to another part.

Network types

Computer network types can be categorized by scale or range, connection method, functional relationship, network topology or specialized function, among others. We will focus on the most commonly used classification: by scale or physical size.PAN (Personal Area Network)

Purpose

PAN networks link devices such as smartphones, tablets, PDAs, printers, laptops or desktops, by cable, for data transmission within

LAN (Local Area Network)

Yes, known as WLAN network (Wireless Local Area Network) the nodes are connected through Wi-Fi technology or Bluetooth and can reach a distance of up to 20 km. 

MAN (Metropolitan Area Network)

Purpose

MAN networks are similar but larger than LAN networks (in fact MANs connect LANs to one another at high speed).
These networks are usually designed for towns and cities.

WAN (Wide Area Network)

Purpose

A WAN network is an unlimited set of LAN and MAN networks connected to each other.

GAN (Global Area Network)

Purpose

GAN networks are composed of different interconnected WAN networks, the best example of this type of network is the global positioning system (GPS).

what is a wan

what is a wan? A wide area network (WAN) is a telecommunications network that extends over a large geographical area for the primary purpose of computer networking. Wide area networks are often established with leased telecommunication circuits

WANs do not just necessarily connect physically disparate LANs. A CAN, for example, may have a localized backbone of a WAN technology, which connects different LANs within a campus. This could be to facilitate higher bandwidth applications or provide better functionality for users in the CAN.

WANs are used to connect LANs and other types of networks together so that users and computers in one location can communicate with users and computers in other locations. Many WANs are built for one particular organization and are private. Others, built by Internet service providers, provide connections from an organization's LAN to the Internet. WANs are often built using leased lines. At each end of the leased line, a router connects the LAN on one side with a second router within the LAN on the other. Leased lines can be very expensive. Instead of using leased lines, WANs can also be built using less costly circuit switching or packet switching methods. 

wifi monitoring tools

In today’s world an IT organization, you’ve seen wireless networks quickly evolve from a convenience offered to employees to a mission-critical component of your IT infrastructures. Wireless users now expect comparable performance and availability to wired networks.

Organizations enjoy the flexibility of Wi-Fi network access; however, it poses a host of challenges for network managers. Most managers lack the tools and visibility to effectively monitor their wireless networks, much less make informed planning decisions and proactively manage their performance.

Monitoring wireless performance is more complex than wired networks. The range of wireless access points (APs) can be affected by a number of issues, including building materials. As more users connect to a wireless access point and it is oversubscribed, performance begins to degrade. And as APs age, their performance begins to decline.

The Manage Engine Wi-Fi Analyzer and Surveyor can be used to effectively monitor signal strength and display channel graphs on all available Wi-Fi networks. You can use the Wi-Fi monitoring tools to detect slow Wi-Fi networks and identify channel interference and poor signal strength.

wi fi support

Operating system  Wi-Fi support is the support in the operating system for Wi-Fi and usually consists of two pieces: driver level support, and configuration and management support. Configuration and management support consists of software to enumerate, join, and check the status of available Wi-Fi networks.

Wi-Fi is wireless LAN, It is one of the important technologies of the computer networking, It allows the users to connect to the internet technology without the wires, It allows the router to be cordless also, The network is connected through an access point for internet and it is connected to a USB Port.

Wi-Fi   is a family of wireless networking technologies, based on the family of standards, which are commonly used for local area networking of devices and Internet access. Compatible devices can network through a wireless access point to each other as well as to wired devices and the Internet.

wifi management

WiFi Network Manager's are administrative software / applications that are used in controlling, manipulating and configuring the various devices on a wireless network. User managers are a typical example of network managers as they are used for granting access and monitoring the various members of a network.

Wifi management provides WiFi internet access for guests, residents and employees throughout a property. The design typically include devices such as wireless controllers, wireless access points, switches and extensive cabling.

The WiFiTel Network Manager is packaged enterprise standard hardware and software components integrated into a unified system with a cloud interface.

Designed for large networks with a high density of WiFi Access Points the WiFiTel Network Manager includes advanced features that set it apart from other WiFi network management systems and ensure that problems affecting user quality of service are automatically prevented, resolved or mitigated.

managed wifi providers

The days of spotty connectivity and Internet cables are far behind us; these days’ people expect instant connectivity .And when it comes to a business setting, quick and easily accessible Wi-Fi connectivity is not just about ease of business, it has tangible benefits such as enhanced productivity, efficiency and teamwork.

In the past decade, the business WLAN scenario has changed completely; from managing a few access points (AP) to provide wireless hotspots for a small number of employees, office Wi-Fi is now expected to provide complete enterprise-wide coverage to hundreds and thousands of users.

To manage this new scale of wireless connectivity demand and to ensure that scores of employees, guests and users are provided instant and secure connectivity, Managed Wifi providers, enterprises need to rope in professional service providers to manage their Wireless LAN.

Cloud based Wi-Fi services is the way forward; the entire WLAN ecosystem is managed remotely by the service provider ensuring a secure, scalable and stress free Wi-Fi network.

A managed WLAN solution is more than just managing user access, it can comprise the entire life cycle of WLAN – from designing, engineering and installing the wireless systems to managing the entire network. Cloud managed Wi-Fi uses a flexible subscription based payment model to deliver centralized management for authentication of users and network monitoring.

wifi support

WiFi support is the name of a wireless networking technology that uses radio waves to provide wireless high-speed Internet and connections. Wi-Fi networks have no physical wired connection between sender and receiver by using radio frequency technology -- a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space.

Wi-Fi's wavebands have relatively high absorption and work best for 

line-of-sight use. Many common obstructions such as walls, pillars, home appliances etc. may greatly reduce range, but this also helps minimize interference between different networks in crowded environments. 

Wi-Fi is potentially more vulnerable to attack than wired networks because anyone within range of a network with a wireless network interface controller can attempt access. To connect to a Wi-Fi network, a user typically needs the network name .The password is used to encrypt Wi-Fi packets so as to block eavesdroppers. Wi-Fi Protected Access (WPA) is intended to protect information moving across Wi-Fi networks and includes versions for personal and enterprise networks. Developing security features of WPA have included stronger protections and new security practices.

Wifi support provides service in private homes, businesses, as well as in public spaces. Wi-Fi hotspots may be set up either free-of-charge or commercially, often using a captive portal webpage for access. Organizations, enthusiasts, authorities and businesses, such as airports, hotels, and restaurants, often provide free or paid-use hotspots to attract customers, to provide services to promote business in selected areas.
