Types of Computer Network Technician Tasks


A computer technician is someone who specializes in computer repair, maintenance, installation and equipment. Computer is a general term and includes everything from desktop computers to super computer monitoring changes in the Earth's atmosphere. There are four types of computer technicians: repair, networking, infrastructure, and server . The four technicians have the same background and skills. Jobs that specialize in different aspects of computer technology require additional education and experience.

A computer technician skilled in repair is usually trained in general hardware structures, how components work together and diagnoses. To work in this field, most people have taken a short course in computer hardware, called A + Certification. This 12-week course covers basic background, technology, and problem solving skills needed to fix common problems.

Additionally, special programs are available for laptop repair. Manufacturers often provide courses about their own products for technicians who work in registered service centers. This technician learns how to make approved repairs and identifies unauthorized repairs.



Types of Computer Technician Tasks

A computer repair technician checks computers, laptops, monitors, and printers to determine what the problem is. They are looking for damaged parts, burned components or other things. Once they have diagnosed the problem, they can repair the unit or replace damaged parts with new ones.

A network computer technician has received training in networking, installing system configurations and troubleshooting. They usually complete a community or college career program on a computer network. A network computer technician is responsible for the initial set up and maintenance of computer networks. This includes both hardware and software components. For a day, they monitor network activity, install software patches, allocate resources to meet different needs and manage printer servers.

An infrastructure computer technician is focused on the design and implementation of large computer networks. They have a university degree in computer science or computer networking. Part of their responsibility is to determine the correct location for computer equipment. This location must provide the ability to manage heat and power issues related to computer networks.

A server computer technician specialized in installation, scoping and management of large server farms. This location has a large number of servers running simultaneously to meet client needs. A server technician who usually has a university degree and is certified in server technology.

 Mobile users

With the increase in the number of mobile workers and the number of mobile devices, we are logically asking for more mobile connectivity to computer data networks. This demand has created a market for wireless services offering more flexibility, coverage and security.

 New devices with superior capabilities

Computers are just one of the types of peripherals that today are involved in information networks. We are witnessing the emergence of a host of exciting new technologies that can leverage the available computer network services.

The features offered by mobile phones, PDAs, organizers, and converged pagers on unique portable devices that have seamless connectivity to service and content providers. These devices, once considered "toys" or luxury goods, are now an integral part of our communication. In addition to these mobile devices, there are also VoIP devices, gaming systems, and a variety of family and business gadgets that can connect to and use computer network services.

 Increase in the number of services available

The widespread adoption of technology and the rapid pace of innovation in computer network services is creating a growing dependency phenomenon. To meet the requirements of users, new services are introduced while the previous ones are improved. When users feel comfortable with these extended services, they demand even more capabilities. The computer network is developing to meet this growing demand. People depend on the services provided on the computer network and therefore on the availability and reliability of the underlying computer network infrastructure.

It is incumbent on well-trained IT professionals and computer networks to keep pace with the ever-expanding network of users and services.




 Career opportunities in the field of computer networks

Careers in information technology and computer networks are subject to increasing demand and are constantly evolving as are the underlying technologies and services. As computer networks become more sophisticated, so does the demand for employees with computer networking skills.

In addition to traditional IT professions (programmers, computer engineers, database administrators and network technicians), new network architect positions, e-commerce site designers, information security managers and home automation specialists are emerging. . Opportunities abound for daring entrepreneurs.

Even jobs outside the IT sector, such as those in the field of production management or medical equipment design, now require strong knowledge of the operation of computer networks.

In many large companies, technology managers cite the lack of qualified personnel as the main cause of delay in implementing new innovative services.

As we study the technology of computer networks, we will focus on the components of computer data networks and their role in the activation of communication. This course is designed to provide you with the computer networking knowledge you need to design and manage these evolving IT networks.

 Network definition 
A computer network is a set of interconnected equipment for exchanging information.

 Advantage of the computer network 

A computer is a machine for manipulating data. Man as a communicator quickly understood the value of linking these computers together so that information could be exchanged.

A computer network can serve several distinct purposes:


  • Sharing resources (files, applications or hardware, connecting to the Internet, etc.)
  • Communication between people (e-mail, live chat, etc.)
  • Communication between processes (between industrial computers for example)
  • Guaranteed uniqueness and universality of access to information (networked databases)
  • The multiplayer video game
  • Networks also make it possible to standardize applications, we generally speak of groupware to qualify the tools allowing several people to work in a network. For example, e-mail and group calendars make communication more efficient and faster. Here is an overview of the benefits of such systems:
  • Reduce costs by sharing data and devices
  • Standardization of applications;

Network technician job - features


In the 21st century, with the rapid development of information technologies, the pace of life is increasing, and the main resource area is information that “compresses zaman and accelerates time.

In modern conditions, knowledge, intelligence, culture, education, intelligence should become a priority in the life of a modern man. The main aspects of innovative education are democratization, humanization, basicization, informatization, integration, multivariate, technological and modern society as determined by the social order as it requires professionals in demand in the labor market. Education, as a sociocultural phenomenon, focuses on the formation of personality and performs the most important functions of professionalization and socialization.

These changes affect not only sound values ​​but also the choice of the profession; it is a measure of the accuracy of the decision in the practical sense. In addition, Russia's entry into the global knowledge field requires the most widespread use of the latest information technologies and, above all, computer networks.

Today it is impossible to imagine any business, organization, technological process or production, education process or entertainment industry in modern society without using computer technology. Sooner or later, for most businesses and organizations, automation becomes more relevant than ever, and many executives try to use the benefits of modern information technology. As a result, the programmer is a kind of consultant with an intermediary function between what the supervisor wants and what the high-tech world is currently offering. An important feature of information technology is, without a doubt, computer software and computing equipment.

At the same time, the capabilities of the user are dramatically increased and qualitatively changed both in the services it provides to its customers and in solving its own organizational and economic tasks. Information technology, development and improvement, changes business: management mechanisms, communication methods, provision of services and production of goods. Thus, a modern information society is established. Therefore, programlama Programming in computer systems ”is one of the most popular not only in Russia but also in the world.

Programming is now a rapidly evolving field, and the programmer needs to be able to quickly adapt to existing technology and constantly learn new ones.

When he was born, programming looked like art, because the basic laws and rules had not yet been solved. It is noteworthy that the first programmer was a woman - Ada Lovelace, daughter of the famous British poet Byron. In 1833, the English mathematician C. Babbage invented and founded the first model of a mechanical "analytical" machine that performed the simplest arithmetic operations. Ada Lovelace wrote several programs for this machine. Digital computers appeared in the 40s of the 20th century. The idea of ​​creation belongs to the American mathematician von Neumann. For the first generation machines, highly detailed programs have been compiled, providing every step in every calculation process. Moreover, the machine has yet to understand another language. Currently, there are numerous developments in the field of computing and programming, and an incredible success has been achieved. The future of computerization,



Thanks to international standards, the ease and speed of deployment of new products and technologies (the Internet has become the peak), programming lags far behind other types of production.

This expert computer equipment ensures uninterrupted operation of software in the local network, offices and companies. He is responsible for network security, computers and computer programs. Its task is extensive - write websites to purchase hardware and parts. Such a wide range of information is highly valued and well paid. In the competence of an expert, in this case, it can serve businesses with numerous user stations and powerful servers, or work with small companies' local networks.

The dominant activities of the programmer profession today   developing programs to solve various problems based on the analysis of mathematical algorithms: selection of the numerical solution method of the problem, ie reduction of complex mathematical formulas to basic arithmetic operations; preparing an algorithm - a detailed plan to solve the problem - or selecting the most appropriate algorithm to solve this task; definition, volume, structure, schemes and schemes of information to be processed in a computer, input, processing, storage and export of information, control methods; determining the likelihood of using ready programs; programming language selection and translation of models and algorithms used; program debugging and debugging and preparing for adjustments; developing instructions for working with programs; participation in the creation of technical documentation; ; supporting programs and software implemented; development and implementation of programming automation techniques.



The success of the implementation of the professional activities of the programmer provides qualities such as logical thinking; flexibility and dynamic thinking; ability to analyze the situation (analytical skills); good memory development; High level of concentration, volume, distribution and switching attention; the ability to articulate his thoughts; high level of technical ability; mathematical skills; imagination developed.

Personal qualities, interests and trends are also important: attention; cleaning; patience; persistence; undertaking; responsibility; tendency for intellectual activities; to make decisions independently; independence. The programmer must develop his horizon and his level of thinking. Most of these depend on the individual qualifications, but you need to work hard on your own to become a true professional (for example, the independent work of languages ​​and technologies).

This expertise is and will be of great importance in professional and everyday life. The programmer has a wide range of interesting and promising areas in the use of his knowledge and skills.



Software technicians work in computer centers, IT companies, banks, educational institutions. They are interested in software development, computer troubleshooting, equipment tuning, user training. It also updates databases, which are the software used, and monitors the validity of the license agreements for the operation of the programs. Prepare technical instructions for working with computer programs. A computer systems technician develops and manufactures software and hardware systems, operates and maintains computer systems, discusses technical support and configuration of the system as a whole, and ensures the protection of information in software systems of computer systems. Establishes and configures peripherals, designs digital devices,

Without these experts, technical progress of the future is not possible and the need for qualified personnel is increasing in city enterprises.

The salaries of computer network equipment are very high even for beginners in their careers. Although it does the work necessary for businesses and production, it does what it wants, because people who are truly in love with technology enter this profession. When applying for a job, a person with a degree in Computer Networking can be both the system administrator's position and the technician in designing the cable structure of computer networks, as well as an installer in setting up and operating them. Even the most advanced specialist cannot find a job according to his level of knowledge and then gradually learn and gain experience. During the study, it is important that the programmer develops his / her expertise and develops himself / herself professionally.

NEW CHALLENGES FOR NETWORK ENGINEERS



The old Chinese saying seems to be accurate as the present arrangement of changes move through the systems administration industry. Not exclusively are we finding out about NFV and SDN, there are new transport conventions that will require new training and new investigating devices. I wound up mindful of the new conventions when finding out about WebRTC (program based continuous coordinated effort – video in the program). (See "Accelerating the Internet" for a related post about accelerating the Internet.)

Pause! New transport conventions? What's going on with TCP and UDP? Indeed, there are a few things that could be improved. Rather than rehashing them here, you can find out about them in RFC4960, Stream Control Transmission Protocol, Section 1.1. Furthermore, these issues do exclude the effect of bufferbloat on TCP throughput.

UDP has its own issues. Programming engineers need to assemble message dealing with, discontinuity and reassembly, and blockage control into their applications. That is a great deal of work and a ton of code to incorporate into every application.

The new conventions are the Stream Control Transmission Protocol (SCTP—see RFC4960), SPeeDY (SPDY—see "SPDY: A trial convention for a quicker web"), and Quick UDP Internet Connections (QUIC—see "QUIC, a multiplexed stream transport over UDP"). SCTP was made to ship PSTN motioning over IP systems without the issues of TCP. SPDY was made, essentially by Google designers, to improve the exhibition of HTTP on the wire. It performs HTTP multi-stream pressure and encryption with SSL/TLS over TCP. QUIC is a successor to SPDY that utilizations UDP as its vehicle so as to dodge a portion of the issues inalienable in TCP. As per Google, about portion of all Chrome program collaborations with the Google web index are utilizing QUIC. Another fascinating goody about QUIC is that utilizing UDP permits its blockage control components to be created outside the OS bit. Making changes to part systems administration code is almost outlandish, so moving the errand into client space code enables analysts to effectively send new advancements without requiring an OS overhaul. This is cool.



These new conventions are great. They address a significant number of the issues and wasteful aspects of conventional conventions. We should see how these new conventions work and how to investigate them, similarly as we needed to comprehend TCP's windowing usefulness over long fat pipes so as to accomplish high throughput streams.

There are different changes that these conventions bring. Firewalls and burden balancers should comprehend and deal with the new conventions. Stateful firewalls, specifically, should be altered to deal with QUIC, which keeps running over UDP and can begin an association between a customer and server in a couple round-trip times. The encryption and pressure of information on the wire will necessitate that system examination devices be refreshed to comprehend and disentangle the new conventions. Devices that sniff parcels on the wire, as Wireshark and Application Performance Management frameworks, should adjust to the new conventions. I'm certain we'll likewise require new investigating apparatuses to enhance the current instruments.

The 5 Issues That Are Affecting Large Computer Networks Today


In the present business world, huge systems have turned into the standard. Be that as it may, they carry with them an interesting arrangement of difficulties, both when keeping up and planning them. In little systems, you can without much of a stretch neglect minor issues, however in an enormous system, you essentially can't stand to slack, since it will carry the whole system foundation down with it. 

This is the motivation behind why IT system care staff and security work force are the ones who need to oversee enormous systems, and attempt to recognize issues that represent a danger to the system. It tends to be hard to distinguish issues with a huge system in light of the fact that there are loads of issues that can influence a system. The regular issues can be effectively recognized and managed, however there are sure issues that can be dubious to oversee. These issues fall under the accompanying classes: 

 Performance corruption 

 Host recognizable proof 

 Security issues 

 Configuration clashes 

 Network execution issues 

So as to enable you to manage the five issues that are influencing huge PC arranges today, we will be taking a top to bottom investigate them and their answers. 

1. Execution Degradation 

When you experience loss of information trustworthiness and speed in a system, it is commonly down to poor transmissions and is otherwise called execution corruption. Each system, regardless of whether little or huge, will have execution issues, yet in huge systems there will be more issues, on the grounds that there is extra hardware at midpoints, endpoints, and extra separation included. 

Fortunately there are loads of straightforward answers for beat the numerous presentation related exhibitions you will undoubtedly involvement in enormous systems. The principal thing you have to do is purchase the best PC organizing equipment you can discover, in light of the fact that you need strong systems administration equipment to have a decent establishment for your system. The parts you use in your system are going to influence execution, which is the reason you shouldn't settle on your system equipment. 

Quality is significant when picking system equipment, yet the amount can likewise be an issue. Ensure that the equipment you buy for your system is with appropriate arrangement, and that it has enough area controllers, switches, and switches. On the off chance that you don't have the correct arrangement for your equipment, at that point it will at last be totally futile. 

It is significant that you ensure that every one of the PCs and system are associated and designed appropriately. This implies checking the system settings in the work area system and server design applications, and checking the settings of all the system parts. Every one of the gadgets associated with the system must be routinely checked for issues, as botware, spyware, and infections. This is on the grounds that such issues can squander transfer speed, and furthermore taint different frameworks associated with the system. 

2. Host Identification 

With regards to have distinguishing proof, you have to get legitimate setup, on the grounds that without a location, your PC organizing equipment will be not able send information and messages. Little systems don't for the most part have this issue, since they can be effectively arranged with the assistance of manual tending to, however this turns into a difficult issue in huge systems. 

The space controllers, DHCP servers, and their tending to conventions and programming are vital, when you're constructing and keeping up a major, adaptable PC arrange. Legitimate host distinguishing proof is important to get top execution from your system, however you likewise need to concentrate on keeping it secure from programmers too. 



3. Security Issues 

One of the most significant issues in any PC system is the security issues, which for the most part include shielding the system from disavowal of administration assaults (DoSA), counteracting unapproved clients to penetrate the framework, and keeping up system uprightness. These system issues increment in size as indicated by the size of the system. Huge systems are defenseless to assaults, since they have progressively helpless focuses, which gatecrashers can access. The more clients a system has, the more passwords will be utilized, and this will mean the more equipment puts a programmer can attempt to penetrate. 

It is significant that you have first rate security for your PC arrange, which will incorporate utilizing intermediaries and firewalls, conveying severe secret phrase approaches, physically verifying PC organizing resources, introducing solid antivirus programming, conjuring strategies to compartmentalize huge systems, and utilizing system investigation programming. 

4. Arrangement Conflicts 

A little system will for the most part have several thousand IP addresses with extraordinary host names accessible, and there will be a little possibility that a specific gadget will struggle with another. That is the reason you should include different courses, with the goal that you can sidestep the issues of a bustling system. Enormous systems need to manage arrangement clashes and occupied systems, since they have much more traffic experiencing the system. 

In any case, to guarantee that you don't have extensive arrangement clashes on your system, you ought to guarantee that the system structure is planned such that manages design clashes. This will imply that you procure the administrations of an expert system arrangement and configuration counseling administration like Noel Network IT Support. 

5. System Performance Issues 

An enormous system will likewise need to manage various system execution issues, which might be brought about by switches and switches with lacking steering tables. This will cause the gadgets associated with the system to have execution issues, and the most ideal approach to manage such an issue is to buy new system equipment that doesn't have any presentation issues. 

This implies you should pick a brand that has solid equipment parts for organizations with huge systems. This will understand most of your presentation issues, as long as the system has been built in a keen manner. 

These five issues influence enormous PC arranges today, yet can likewise be found in little to-fair sized organizations also. In case you're managing comparative issues or hoping to build another PC organize, at that point connect with Noel Network IT Support to enable you to out with structuring, conveying, and dealing with a huge systems administration arrangement that is directly for your business.

What jobs are incorporated into a system architect set of working responsibilities? 

System architects have an assortment of obligations that fall inside different classes and require shifting abilities. All potential system engineers, in any case, ought to have a general comprehension of the various layers of system correspondence conventions, similar to IP and TCP. Specialists that skill these conventions work can all the more likely create basic systems administration intelligence, as per Terry Slattery, head modeler at NetCraftsmen. 

The job of a system designer is perplexing, which is the reason it's frequently isolated into subcategories. Potential duties incorporate the accompanying: 

  • structure
