It's the ideal opportunity for each student to figure out how to code

Figuring out how to code is about more than vocation availability. It's about offering understudies some assistance with making feeling of their advanced world

Recently, there has been a lot of discussion around the importance of coding in the K-12 classroom. Should it be compulsory for all students? An elective! Reserved for those students considering a computer science major in college?

The answer may come down to supply and demand. According to the Bureau of Labor Statistics, by 2020, there will be 1.4 million computing jobs and only 400,000 computer science students to fill those roles. This represents a gap of one million jobs that will go unfilled, and amounts to a $500 billion opportunity lost.

In 2015, when more schoolwork, from kindergarten up through school, is done in an advanced domain, understudies need to know the essentials of how the framework they are utilizing capacities. By joining coding and software engineering into our educating beginning in primary school, we can close this crevice and guarantee we have enough people with the right information and mastery to fill these employments.

Why coding for everybody?

Some portion of training is professional and a million well-paying software engineering employments absolutely fit that shape. Be that as it may, a just as vital piece of the instruction experience is motivating interest, showing kids how to think, and offering them some assistance with learning about our general surroundings. Regardless I recall when my most loved 6th grade instructor taught us about circuits. I spent a week sticking tin foil to cardboard to make a pin ball game. The deciding result scarcely worked, yet in the event that you tenderly moved a metal ball in simply the right way, it beeped. Infrequently, Most of us will never utilize electronic circuits in our employments. Indeed, even in the wake of working in PC programming for a long time, I've never at any point needed to consider circuits. Yet, taking in the essentials of power offered me some assistance with understanding how the lights in my home function; the idea of option vitality; and urged me to investigate the world. For quite a long time, we've taught these sorts of basics in K-12 instruction: how plants transform daylight into vitality through photosynthesis or how our body separates proteins amid absorption.

In today's reality, seeing how the web works or how PCs separate issues is a major, important piece of understudies' lives. Regardless of the fact that they don't go ahead to major in software engineering, it can offer them some assistance with understanding the PC frameworks they'll be utilizing each day—in school, profession, and past. Furthermore, for some, software engineering will be a piece of their vocation regardless of what field they go into. Actually, 66% of the software engineering occupations are outside of the tech business.Today, we see promoting and political groups utilizing PCs to examine the information from their crusades and track how their messages are arriving with clients. Specialists are utilizing PC projects to dissect proteins and plan new medications. Specialized craftsmen are making activity's in motion pictures and programming. Different applications are correspondingly changing the substance of law, assembling, and even instruction.

When to begin

Many teachers don’t consider starting computer science education in kindergarten, but that’s precisely where to begin. In elementary school, kids approach computers with curiosity. In particular, girls are more likely to pick up computer science when they are young, before anyone has told them they can’t do it. And they are eager to learn: kids love the kinds of logic puzzles programming involves. (In fact, the first course on Code.org, the organization I work with, is designed for children who can’t yet read.)

Another huge misconception that steers students away from computer science is that you need to be stellar in math. While it is true that there is some math in computer science, much of it is not math focused, and you can easily start with concepts that don’t require any math. Our K-5 classes teach students how to think logically and break down a complicated problem into a series of steps—both skills that will hopefully benefit math instruction, but don’t require math prerequisites themselves.

Speaking in blocks

A question we often hear from schools is “Which computer software language we should be teaching? Python? Javascript ?  Something else?”

There are a modest bunch of code dialects out there and their timeframe of realistic usability changes rather rapidly. The dialects utilized today might possibly be the dialect utilized 20 to quite a while from now, so as opposed to focusing on a particular dialect, we ought to first be concentrating on the rudiments of software engineering. At Code.org, the first "dialect" we utilize is squares, and these foundational ideas can interpret over any of the coding dialects that the understudies will learn later on.

Beginning understudies with a customary coding dialect can be disheartening, as they need to get all the accentuation right all together for their applications to work the way they anticipate. We'd preferably let the understudy concentrate on the objective than the accentuation. Utilizing pieces likewise implies that understudies don't need to know how to sort to start learning software engineering. They can move and customize obstructs with a mouse on the PC or with their finger on a tablet. Notwithstanding, once an understudy has the foundational ideas, taking in a particular dialect comes effortlessly.

Beginning

A great way for teachers to get started and introduce students to computer science is to take part in the “Hour of Code”—a one-hour introduction to computer science, designed to demystify code and show that anybody can learn the basics. Anybody can host an Hour of Code at anytime. Some of the tutorials even work “unplugged”—that is without computers in the classroom.

Computer science foundations, even at the lowest level, are an important and powerful set of skills to have, especially in this economy and this enriched digital era. Educational institutions have the opportunity to recognize and support the need for these skills. Teaching computer science will help us produce graduates that are fully college ready and prepared for the workforce, no matter what career field they end up pursuing.

Penetration Testing: A Testing in Computer Networks

Penetration Testing is the technology which has been recently introduced which is used to test networks, applications, and even people, for security holes. It is performed by trained professionals who identify security vulnerabilities in the IT Systems of an organization, in order to eliminate them before hackers or unauthorized users exploit them.

So, for penetration testing, organization will hire a skilled (ethical) hacker to try to break organization’s security systems to check how secure they are. This enables administrator to identify potential security threats & fix them early, save money, prevent lost data, reputation loss, litigation expenses, etc. Penetration Testing also provides a good case for security investments and up-gradations.

There are mainly three types of penetration testing:

  • Network Penetration Testing.
  • Application Penetration Testing.
  • Social Engineering.

The first two are technical activities that test security vulnerabilities in network components or structure , and applications hosted within the company, respectively. Social Engineering tries to exploit weaknesses in the people working for a company. For example, employees can be tricked to click a malicious link sent via email or insert a USB drive with malware into their office computer, etc. to check if their systems can be compromised.

The three main areas to test are: Physical structure, logical structure & response or workflow of the system. Penetration testing can be done from an external location to simulate the activities that maybe undertaken by a potential hacker, or it can be done from within the company to evaluate the extent of damage that can be inflicted by an employee with standard access credentials.

Penetration Testing Methodologies are of three types:

  • Black Box Testing: Testers have no knowledge about the test target. Like an external attacker or hacker, they have to find out loopholes from scratch.
  • White Box Testing: Testers are provided with information about the test target.
  • Grey Box Testing: Testers are provided with partial information about the test target.

There are Three Stages of Penetration Testing:

  1. Test Preparation: Determining the scope, objective, timing, downtime, legal implications, data integrity, etc.
  2. Actual Testing: Information gathering, vulnerability analysis, vulnerability exploits.
  3. Analysis: Reports, Suggestions, Corrective measures to be undertaken.

Some Techniques Used in Penetration Testing:

There are both commercial and open source tools that enable a tester to conduct penetration testing on a company’s network or application servers. Some techniques employed by penetration testers are given below -

  • OS Detection, Remote OS Fingerprinting
  • TCP Fingerprinting
  • Network Scanning
  • Port Scanning
  • Web Server Fingerprinting
  • Auditing Proxy and LDAP servers
  • Developing and executing exploit code
  • Detecting vulnerabilities, mis-configuration
  • SQL injection, Remote file inclusion for PHP applications
  • Password cracker
  • Interceptors, etc.

Networking Certifications FAQ’s

What are the most popular certifications in Computer Networking?

The most popular, or most common, certification track in networking is Cisco's routing and switching series, which comprises the CCENT, CCNA, CCNP, CCIE & CCAr. Most networkers obtain the CCENT or CCNA in routing and switching as their first certification, and many progress upward or outward from there. Other than Cisco, Juniper maintains its own line of certifications roughly in parallel to Cisco's. Although there isn't quite as much demand for Juniper certifications at the entry level, the JNCIE is reasonably sought after. There's also CompTIA, which offers the vendor-neutral Network+ certification, although historically there hasn't been much meat to this cert. Of course, a number of other companies also sponsor certification programs pursuant to their own market interests: These just seem to be the most popular. There are also a number of companies and non-profit organizations which offer certifications focused on security, wireless, virtualization, and other niches that are of value to many networkers.

How much is certification X worth?

A lot of newcomers to the networking field think that a certification will guarantee them a certain position or salary. Unfortunately, this is not the case. Remember, in essence a certification is just a good reference: The certification sponsor is vouching for your abilities to the extent they were evaluated by whatever tests you passed. It has value to a potential employer only if he trusts the integrity of the certification and he is in need of someone with that specific skill set. For example, a Cisco CCNA certification isn't very appealing to a company whose network is comprised mostly of Juniper routers and switches.

A lot of candidates are disappointed to learn that they aren't entitled to the same salary as a friend with the same certification. The most commonly overlooked factor in compensation is location: A professional working in metro city might easily take home twice the income of someone doing the same job in a small town, an income disparity driven by regional differences in both demand and cost of living. Also keep in mind that experience generally trumps certification, as skill demonstrated through the execution of real world projects carries much more credibility than a good grade on a test.

How should study for certification exams?

There are plethoras of study resources out there for just about every certification, and it can be difficult to tell which approach is ideal for you. There are a few basic core types of training material you would like to consider.

Books

Your first step in studying for a certification should be to purchase a book or two pertaining to the topics the certification covers. Just search for the certification name on Flipkart, Amazon and you're likely to find several titles from various publishers. O'Reilly, Cisco Press, and Sybex (Wiley) are all very well established brands and usually a safe bet. Always read customer reviews before purchasing a book, and make sure you're buying the most recent edition applicable to the exam(s) you plan to take.

Books are recommended as the primary study material for a certification because they provide a thorough overview of the content on which you'll be tested. They provide an economic method to judge your level of preparedness before spending money on more costly study tools like exam simulators and instructor-led classes. They also provide much more in-depth content for you to establish fundamental competency with the exam material.

Training Videos

Prerecorded training videos such as those from Udemy, NPTEL, EdX and many other websites offer a nice compromise between books and live classes, both in content and in price. Some people prefer videos because they tend to focus better when they hear a person talking to them and have something to watch rather than having to trudge through pages of stagnant text. Video training generally doesn't go into as much detail as books due to time and production constraints, but it can serve as a great refresher for topics you haven't visited in a while. Video training usually costs more than books but considerably less than live classes.

Instructor-Led Classes

Live classes or "boot camps" are the most costly preparation method (some even include a voucher for the certification exam), but they also have the unique advantage of a human instructor who can provide immediate answers to your questions. Most classes run for one or two weeks at a time and need to be scheduled well in advance. Some classes can cost several thousand rupees, so be sure to shop around and check out reviews from prior students before paying amount.

One downside to instructor-led classes is that they don't always operate on your schedule. Some training providers will claim that they run classes regularly, but abruptly reschedule you if they don't have enough students to justify the cost of hosting the class for a given week. Be sure to get a commitment in writing to the dates you've chosen if your schedule isn't flexible.

If you have no prior experience with the topics to be covered, never start with a live class: You only have a fixed number of hours during which you can take advantage of the instructor, and these are far better spent solidifying existing knowledge and filling in gaps than learning fundamentals. At a minimum, read a book or two on the topics to be covered before scheduling a class so you can hit the ground running on the first day.

Lab Practice

The most reliable way to evaluate your skills is to try them out on real network gear. Lab practice is highly recommended, but only after you're reasonably familiar with the theory and configuration concerning the features and protocols you want to implement.

The Benefits Of Being CCNA Certified

CCNA is one of the most vouched and valued IT certification throughout the world. As much as or even more than 1 million CCNA certificates have been awarded since it was first launched in 1998. So it is not by fluke that Cisco has achieved such humongous figures.

Cisco certifications have benefited both the employee as well as the employer. It is a known fact that many people have literally changed their lives and have got real benefits and acquired valuable skills in the process of becoming certified. There are innumerable instances where individuals having more than ten years or so in their networking career feel the need of getting CCNA certified

It is better to be Cisco certified and do networking, rather until one day you end up not-working.

Here is the list of ten advantages of getting CCNA certified.


[1] Networking Knowledge

In the process of getting your CCNA certification you are sure to increase your knowledge and understanding of the concepts. Even if you have years and years of experience in the field, you would definitely increase your knowledge and skills.

As people say, nothing can replace real world experience, but books are also equally important for keeping up-to-date with the new advancements in the industry. In the course of getting certified you would be bombarded with many advancements of the industry thus increasing your overall knowledge.

[2] Alphabets behind your name

After being Cisco certified, you would be able to write those four magical letters which certainly do matter in these days.So from the day you get certified till the next three years you would be legally and ethically right to use CCNA in your resume as well as in your business card. Apart from this you will get a CCNA card, certificate and letter from Cisco validating your achievement.

[3] Career Advancements

CCNA Certification increases your chances of promotion. You could expect to move up in the hierarchy of your organization.

[4] Salary growth

Your next salary increment could be just around the corner after getting your certification.

[5] Stepping stone for many other certifications

CCNA certificate is a prerequisite for many other Cisco certifications. CCNA concentration like CCNA Security, CCNA Wireless and many other professional level certifications require a valid CCNA certificate.

[6] Respect

Getting a CCNA certificates commands a certain amount of respect from your colleagues and employer. Some of your colleagues would have also tried to get certified, but could not get certified. So, this achievement of yours deserves a back-patting.

[7] Employer benefits

Many employers like to employ certified people because it demands a well standing in the ever-increasing and competitive IT field. That is the reason many employers bear the cost of certification. It's a kind of mutual give and take.

[8] Kick-start your Networking career

Before getting CCNA certified, People used to think as to which option would be better i,e. Cisco or Microsoft. Now, I am certain that Cisco is the better option as the latter does not needs any extensive preparation. I could now get other desktop and Server level Microsoft certifications simultaneously.

[9] On track

After getting certified you would be on the right track to go for many other professional level certifications. Getting the first certification is always hard but once you take the first step, the journey to the thousand miles at least gets started.

[10] Personal Satisfaction

You always wanted to get certified, so after you receive your certification letter and other stuff, a sense of personal satisfaction, gratification, and relief is felt.

Those were few benefits which I mentioned here that people could receive after getting CCNA certified.

Careers in Computer Networking

What Is Computer Networking?

Anyone who has ever sent an e-mail has used computer networking. A generation ago, computer use was still new, but today life would be unthinkable without the benefits computer networking provides. The computer network has become a fundamental tool of today's corporate environment.

Computer networks function on a local area (LAN) or a wide area (WAN) based upon the number of people and the geographic distances involved. These can include a small business with two or three employees to major corporations to the government of the countries. But computer networks exist in realms beyond business. Virtually every aspect of today's society depends on information that is furnished through computer networks. Companies can save millions by sharing resources via computer networks rather than by shipping or traveling. Individuals use computer networking to do their banking from home, communicate with relatives, and even to entertain themselves with music or by playing video games.

Computer networking is the connecting of two or more computers that allows them to share resources. It can be done between computers in a home, in a business, across a corporation, and even internationally. The Internet is the largest example of computer networking because it involves thousands of networks of computers that share information.

Job Titles in Computer Networking

Several types of positions exist in computer networking area, each with different average salaries and long-term potential, and one should possess a clear understanding of these. Unfortunately, job titles in networking and in Information Technology (IT) generally, often lead to confusion among beginners and experienced folks alike. 

The basic job titles one sees for computer networking and networking-related positions include

  • Network Administrator
  • Network (Systems) Engineer
  • Network (Service) Technician
  • Network Programmer/Analyst
  • Network/Information Systems Manager

 

More Computer Networking Career

Some other computer-related specialties that involve networking skills are:

  • Computer Programmer
  • Computer Engineer
  • Database Administrator
  • Web Master
  • Computer-Operations Researcher
  • Computer Repair Specialist
  • Systems Analyst

 

Certification, Licensure and Associations

More companies, especially major employers, seek computer networking specialists who have been certified in specific computer programs or operating systems. Completing a certification training program, which a number of vendors and product manufacturers offer, might help some people qualify for entry-level positions. These programs can be used for promotions by those already working in a computer specialty.

Most people have heard of certifications by Microsoft, Novell, Cisco, and a few others, but few realize there are more than 200 technical certifications that can be earned. Some of these include 3COM Master of Network Science (MNS), Sun Certified Java Developer, Certified Network Expert (CNX), or an IBM Certified AS/400 Professional System Administrator Certifications are available for Apple OSX, Linux, Microsoft's MCSE, MCSA, and MCP, Cisco's CCNA and CCDA, and a great many others.
