What is deffrence Among Private Network, Intranet, Extranet and, Internet?

Private network

the Internet addressing architecture, a private network is a network that uses private IP address space. Both, the IPv4 and the IPv6 specifications define private addressing ranges. These addresses are commonly used for local area networks in residential, office, and enterprise environments.

Intranet

An intranet is a private network accessible only to an organization's staff. Often, a wide range of information and services are available on an organization's internal intranet that are unavailable to the public, unlike the Internet

Extranet

An extranet is a controlled private network that allows access to partners, vendors and suppliers or an authorized set of customers – normally to a subset of the information accessible from an organization's intranet. An extranet is similar to a DMZ in that it provides access to needed services for authorized parties, without granting access to an organization's entire network. An extranet is a private network organization.

Historically the term was occasionally also used in the sense of two organizations sharing their internal networks over a VPN.

Internet

The Internet (contraction of interconnected network) is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide.

what is firewall, VPN(virtual private network) and, Private network ?

FIREWALL: 

a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and untrusted external network, such as the Internet.

Firewalls are often categorized as either network firewalls or host-based firewalls. Network firewalls filter traffic between two or more networks and run on network hardware. Host-based firewalls run on host computers and control network traffic in and out of those machines.  

VPN(virtual private network):

 A virtual private network (VPN) extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running across a VPN may therefore benefit from the functionality, security, and management of the private network.

VPN technology was developed to allow remote users and branch offices to access corporate applications and resources. To ensure security, the private network connection is established using an encrypted layered tunneling protocol and VPN users use authentication methods, including passwords or certificates, to gain access to the VPN. In other applications, Internet users may secure their transactions with a VPN, to circumvent geo-restrictions and censorship, or to connect to proxy servers to protect personal identity and location to stay anonymous on the Internet. However, some Internet sites block access to known VPN technology to prevent the circumvention of their geo-restrictions, and many VPN providers have been developing strategies to get around these roadblock

7 Things You Should NEVER Include On Your CV.

this article is taken from linked in by Lima sehgal

Job seekers tend to focus on what to include on their resume, but it is equally important to know what NOT to include on your resume...

What information to include is in your hands, but remember that even small mistakes can backfire and reflect badly on you and in turn hurt your chances of getting shortlisted.

Here is a list of things that you should NOT include on your CV.

1) Personal Information; What to include and what to exclude:

The basics of personal information that you have to include are Name, Address, Email, and Mobile. This information is necessary for a person to contact you. Make sure that all contact details are current and in working condition.

- Address

Your address has to be a place where you can be reached.

#Avoid giving an address of some remote location even if it is your permanent address. If you have no permanent address or you are changing locations frequently, do not list it. You can give an email ID instead.

- Email IDs

Your email ID must be in working condition and you should frequently check it.

You can include up to 2 email id's on your CV. Just ensure you do not include your current company ID on your CV.

# Do not include email IDs that are descriptive - like sexysanjoo, chooserekha, Manjeetforsuccess - Please choose a mature email ID for your job hunt- the best ones are simple with just combinations around your name.

- Links.

You should include links and details of your Linkedin profile, Skype and website, and to your portfolio.

# What not to include are links that make a person move out of your CV and into your company or college website or to other places on the internet.

- Photographs.

Your photograph needs to show you with a frontal view, in formal attire and a smile. There should be a clear background behind you. Prepare 2 versions of your CV –with and without a photograph.

# Avoid sending your CV with a photograph unless it has been asked for. Someone may reject you for no reasonable fault but just because of how you look. Also remember, photographs are graphic files and are heavy to email, which can lead to technical difficulties in opening your CV or email.

2) Do NOT include statements of self-praise and emphasis:

Many job seekers tend to put in declaratory statements in their “Objective”.

Here are some examples:

Objective: “Talented, multifunctional visionary seeks …”

- “Looking for a middle or senior position with an organization where I can contribute…”

- “Award-winning national sales manager looking for a challenging work environment... “

No company or recruiter is interested in what you want and what you are trying to say so vehemently. They are interested in only what they want.

# Cut it out- Create a short summary instead- just 2 to 4 points maximum telling them what your expertise is so that your value to them is clear from the start.

3) Do NOT include explanations for job changes in your CV.

Many job seekers find it necessary to explain why they left a company in the past.

For example-"Left company because - I had a baby, had an accident, left to avoid relocation, got retrenched, company closed down, left because of no growth prospects, daddy got posted abroad" – The reasons are varied.

This is highly avoidable because the explanations you give can have different interpretations for different hiring managers. Let's take the example given above to get an idea on how others may view it.

Example: She had a baby last year so she has to cope with a 1-year-old kid’s problems- She would be taking leave whenever the kid falls sick. Oh, he had an accident? Maybe he is a rash driver or is he hiding a disability-related issue? She left because daddy got posted out? So next time daddy get another posting she will quit. Got retrenched, the company closed down, left because of no growth prospects? Hey, this may be a person with a problem – probably someone who gets shunted our easily - Maybe because he is dispensable?

#Do not give reasons for leaving a company on your CV. The reasons can be misinterpreted. You can give an explanation for a job change when you are called in for an interview instead.

4) Do NOT include your salary details.

Job seekers tend to mention their current salary details or give their CTC ( Cost To company ) figures in their CV. They mention it either with their current job or give salary figures for all the jobs that they have worked in.

Including salary details on your CV is a fundamental blunder. This is because companies have different structures for salary preparation. And if you don’t fit into their structure you may get rejected. They may also reject you because you are over their budget.

By including it, you are creating a reason for rejection without getting a fair chance to be called for an interview where you get a chance to negotiate or compromise.

# Never include your salary details on your CV. Give yourself the chance to discuss and negotiate your salary requirement during the interview.

5) Do NOT include references, unless specifically asked:

There was a time when references were a necessary part of a CV. Job seekers used to go through a lot of trouble getting references from impressive contacts.

Today, there is no need to give references on your CV. If you are a job seeker, employers know that you can produce references. So you do not have to say – “References on request”.

In today’s environment, a reference check happens to be the employer’s privilege. Every company has their own requirement- It could be talking to your client, your boss, other ex-employers, your colleagues. So if you are selected for a position, they will probably ask you for a specific kind of reference.

# Avoid putting references on your CV when there is no need for it. It makes your CV unnecessarily long. You can produce them when specifically asked to do so.

6) Do NOT include family details.

Job seekers tend to include information about their marital status, kids, employment details of spouse/father, religion.

This kind of information creates impressions about you that you have no control over. Suppose a company is not keen to hire a person who is married, why take the chance of getting rejected without a fair chance? Personal data is not compulsory to show. People are keen to know what you can contribute to their organization. So stick to showing your expertise rather than your personal life.

And never mention your religion on your CV. This is often ground for prejudice and getting rejected.

 # Avoid giving personal information on your CV.

7) Do NOT include a conclusion statement at the end of the CV.

Remove the oath bearing statement at the end of your CV that says- I declare that all information is true and updated to the best of my ability - along with a date and signature. It is understood that you shouldn't lie. Also, it is a CV, not an affidavit.

# There is no need for it at all. It is redundant and it just occupies space.

+++++++++++++++++++++++++++++++++++++++++

Stay clear and concise on what you want to show on your resume. There is so much competition out there, you cannot afford to make mistakes in what you communicate to others through your CV.

Startups: the best place for freshers to work, here's why?

This article is originally taken from linked in by sandeep singh.

Startups: the best place for freshers to work

Joining an early stage startup can be beneficial to your career if you are independent and motivated. You will have plenty of opportunities to wear a lot of hats, take on more responsibility, and learn more than you would have at a larger company.

• Professional Growth: 

Working at a startup is a great place to build upon your existing skill sets, gain experiences in many functional areas, and take on a ton of responsibility. As the company grows quickly, so will your opportunities for career advancement.

• Personal Growth:

Strengthen your team-playing abilities as well as your self-sufficiency. Get the most out of the experience and develop your social skills by wearing many “hats” and making important decisions.

• Your impact on the product:

When you are launching a product, you are spending most of the time getting useful things done. It’s really fast and cheap to add a new feature. It’s even faster to remove that feature and try another one. Also, in a team of 5 or 6 people, you definitely have a massive impact on the product.

• Learning:

The innovative nature of a startup usually allows you to have close contact with the founders who are usually some of the best people to learn from. Also, expect to get a lot of exposure to the intricacies of the entire business operation.

• Diverse Work Schedule:

There’s a lot of work to be done but depending on your work’s perks, you could negotiate a very flexible schedule. working from home or even get weekends off…

• Be Influential:

Fewer layers to the Founders means there is more of a chance for opinions to matter. Moreover, the work you do at a startup makes a real difference and can have a significant impact on the success (or failure) of the business.

• Expand your network:

Get access to industry events, local meetups and build your professional contacts with like-minded professionals. This can go a long way when looking for recommendations or new career opportunities.

• High-level Job Opportunities:

Startups are ever-changing and if you do your job well, you could fast track into a management position a lot quicker than an established company with a defined hierarchy.

• What usually happens to ideas in big companies:

If it’s your idea and you are not an executive, it will take forever to be validated. Then, you need to consider the impact on your users, your tech stack, or the data. So you need a migration plan 😨.

If the migration has an impact on the users, you will probably create a parallel UI. If data need to be migrated, it will certainly take 10x times longer than you think until you make it work in a reasonable amount of time. If it’s an architecture (think migrating from Angular to React, or Rails 4.1 to Rails 5, etc.), we are talking weeks or months of development. Oh, and most of the time the migration is not worth the effort. So you are stuck with your old interface, your outdated data or your inefficient tech stack.

• Be a Part of It All:

And last but by no means least, you should join a startup because it’s a unique experience to help build something and be part of its growth from the very beginning. This means living the high highs, low lows, and everything in between.

Genuine startup investments will be free from taxes, says government

New Delhi: The government on Wednesday assured that genuine investments in startups will not be taxed for exceeding fair market valuation.

The Income Tax Act treats share premium received from the sale of unlisted shares in excess of their fair value taxable as income from other sources.

The assurance comes after news reports said some startups have received notices from the income tax (I-T) department seeking details of their share transactions.

The move to seek clarifications on share premiums under section 56 of the Income Tax Act has been on for a few years.

The idea is to check instances like politicians accepting bribes in the guise of premium for shares in unlisted companies held by them.

However, the government has exempt startups registered under the commerce ministry from the purview of this provision.

The department of industrial policy and promotion (DIPP) said that it has taken notice of news reports. It said that there is a mechanism in place since April 2018 to grant exemption from the provisions of section 56(2) (vii b) of the Income Tax Act to genuine investors in recognised startups.

DIPP said in a statement issued on Wednesday, “DIPP has again taken up this matter of issue of the Income Tax notices with the revenue department so that there is no harassment of angel investors or startups.”

 it added, “Government is committed to protecting bona fide investments into startups.”


However, tax department officials said that only companies that act as vehicles for financial irregularities will be pursued. If the startup can explain how the valuation is justified, there is no tax liability on the premium, said an official, who spoke on condition of anonymity. This is an anti-evasion provision built into the law.

what is a microprocessor? and what is it's work?

A microprocessor is a processing unite which process the data according to our work. it is fabricated on a small chip who’s size is decreasing day by day.

It is made of transistors through the size of transistor is decreasing that's why the size of microprocessors, microcontroller and, chips are also decreasing.

A microprocessor is a small processor. it processes the data which program is currently running in the system. a microprocessor consists of ALU(Arithmetic and Logical Unit), register sets(Array), and control unit.

IT takes the input  while processing it need some memory to fetch the related data and saves the output and gives us the output

processes the data in an instruction cycle.

there are three stapes in an instruction cycle.

1. Fetch

In this stape, the microprocessor fetches(reads) the codes wherever it is saved in the memory (probably copied to the main memory(RAM) before processing)

2. Decode

After fetching the data it decodes it. simply decoding is a process in which the computer let it know that what is going to be performed and what actions are to be taken by the system hardware.

3. Execute

decoding the data when the system knows that what to be done by the hardware of the system it simply execute those instructions.

Features of a Microprocessor

Here is a list of some of the most prominent features of any microprocessor −

Reliability

 − The failure rate of an IC in microprocessors is very low, hence it is reliable.
