Cisco CCENT - CCNA Certification Exam Training - Introduction to the OSI model

As network administrators, we are going to be primarily interested in the first three layers of the OSI model - but for the CCENT and CCNA exam, we need to be involved all seven!

The OSI layers are often referred to by numbers, with the layer of application being level 7 ("L7"), the presentation layer being Layer 6, and so on until the end of the level 1, the physical layer. To get you used to this, I will refer to the layers with their names and numbers of all these tutorials.

The application layer

This is the layer in which the end users themselves interact with the network. Authentication services also operate at Layer 7.

Protocols and services that run at L7 include:

Email POP3 and SMTP protocols

Telnet

HTTP

File Transfer Protocol (FTP)

Simple Network Management Protocol (SNMP)

The presentation layer

This layer responds to one simple question: "How should this information be presented?" In addition to properly formatting the data, encryption occurs at this level.

The session layer

Level 5 is the "manager" of the bidirectional communication between two remote hosts. This is the level which manages the establishment, maintenance and teardown of communication between these two hosts.

The Transport Layer

TCP and UDP, both running at the transport layer, and we got to know both protocols in and out to pass the CCNA and CCENT exams. We will see in those protocols in a future tutorial.

The network layer

And 'at level 3 of the OSI model that you and I, as network administrators are beginning to have a great deal of interaction with the network. Internet Protocol (IP) works at this level, and since the routers operate here to L3, this layer is often called "the layer of routing".

In a nutshell, the routing is a process of two questions:

That there are valid paths from the local router to a particular destination?

What is the best way to go to get there?

The Data Link Layer

Switches operate at Layer 2, as well as wireless access points (WAP). We have four main features that run here, some of which may already be familiar with:

Ethernet

Data at high Link Control (HDLC)

Point-to-Point Protocol (PPP)

Frame Relay

The physical layer

When things get a bit 'complicated network, I like to remind myself that "it's all ones and zeroes!" Whatever the data of our users are creating, eventually is going to be "translated" into a series of 1 and 0. Once that is done, is the physical layer that handles the actual data transmission. Nothing to do with a physical cable - the pin connectors, the electrical current itself - is running at the physical level .......

Gems and conditions - ask for the sale at least once before you leave!

You may have heard the expression that teachers learn by teaching.

Through research, course design, content delivery, discussion and feedback, teachers grow and stay fresh.

The same goes for sales consultants and customer satisfaction, making the area very interesting for me over the years. I study the current practices of my clients, and in many cases, are quite good and I pick up on new concepts and techniques that work, and have not yet been widely disseminated.

One of my clients is the head of his company's office automation, specializing in the sale of Sharp and Toshiba systems. One day, I was watching him form a new group of vendors, and a number of gems thrown their way, one of which I share with you.

He said: "If you had the time to introduce yourself to a prospect, always, and I mean ALWAYS, ask for the sale at least once before you leave!"

This seemed so basic, so elementary, that, of course, his reluctant recruits.

"And if you have not completed the presentation?" one of them challenged.

"Ask for the sale at least once, before leaving," he repeated.

"And if the past has barely said hello, and tell him what you sell?" another query.

"Ask for the sale at least once, before leaving," he echoed as calmly and confidently as anyone I've ever seen.

"And if it is completely screwed up and put his foot in his mouth, then?" Another newcomer asked.

"Ask for the sale at least once, before leaving," he pronounced with the purposes and the sweetness of an essay.

When the questions stopped, and faces doubters have been replaced by smiles aware, went on to say:

"It 's heartbreaking as sellers work harder without cashing in their efforts. If you ask for the sale at least once, you will be amazed by how many offers you can earn, simply because you asked" .......

Tips for starting a new business Trading

Trading simply means the task of finding a buyer and seller of a product and corresponds to be the intermediary for the exchange. You can earn a profit for the price difference to which purchased and the price at which it sells. It is becoming a booming business in line with a growing number of people who realize the vast potential for investment and low inherent to the business. However, as many people find success in trading activity as the number who do not, then you better be ready to use your intelligence and hard work. There is a road paved with gold to easy money, as some people like to think, so keep the following guidelines in mind while starting a new business.

Reliable Source -

You will need to find a solid source, reliable and affordable price for the product. Since you are working on maximizing the margin, you must be sure that will not be charged by the supplier. Also, check the source selected well before you start. Ask for references and talk to other customers of the supplier, particularly those angry. Make a report and use more than one supplier because it is not a good idea to be completely dependent on one supplier, especially initially.

Reliable delivery -

Next you will have a reliable system of delivery, or through the channel of the provider or through your own. Ensure that the system is pretty foolproof. Try it - send yourself a sample of the product. Keep tests from time to time to ensure that the system still works well. Remember that your customers will blame for any loss, damage or delay so your delivery channel must be perfect.

Legal requirements -

Find out if there are any restrictions on your product of choice. Make sure you understand the legal implications of trade in the product and all the surrounding documents. If there is documentation, before starting to complete and, if the documentation is in progress, be sure to factor in costs.

Accounting and Taxation -

Research in detail all the accounting and tax. Talk to people in business, accounting, or search online. When you form your business plan, be sure to take into account all expenses and costs of creating and managing your company's trading.

Credibility -

Building your trust factor is crucial. Customers and potential customers will need proof of your credibility and is essential for recognition as a reliable trading activity. This can be established through references or rating. Make sure you are perceived as 100% reliable, because this is absolutely the first essential step toward getting a customer base.

Communicate -

Create a network of customers and suppliers, in order to be always in the loop for new developments needs of customers and product information. Maintain a constant interaction with these two groups by e-mail / mailing lists, newsletters, forums etc.

Starting a trading business is not rocket science, but it requires effort and common sense, and there is always the possibility of large profits....

High interest savings accounts

Why you should consider opening a high interest savings

For the Australians in particular, there has never been a better time for the application of a high interest savings account, particularly with new bank offers such as Commonwealth Banks' Netsaver 'and BankWest of' Telenet Saver '.

With such strong competition in the Australian banking market, banking firms have no choice but to continue to offer savings accounts and releasing new features with better and better.

Regardless of your socio-economic situation, also having a lower amount of funds in a savings account can compound relatively fast. It provides even less incentive to spend, as commonly, these accounts are not accessible by ATM / Eftpos machines.

Having a separate account interest is reduced to a greater efficiency of storing your money on a traditional current account, by higher interest payments.

They also include extra bonus of saving, such as interests in more if withdrawals were made over a period of time.

According to research conducted by the Bank and Financial Services Association, between 1990 and 2006, the Australian statistically saved an average of about 2.88% of their disposable income - the lowest of all westernized countries. This is far less than the amount of France, for example to 12.1%, which is not yet the leader in the saving disposable.

Be wary of the fine print

Be very careful and make sure you analyze the terms and conditions of your potential new high interest savings account closely.

Although most are truly beneficial, some have negative attributes such as HSBC 'very seriously Saver', which only compounds and adds interest when there are samples to be there for the entire month.

Leaving aside the problems of this type, take care not to avoid the cost and paying regular payments to avoid penalties more severe, or dishonored, bad credit rating.

You have enough discipline to save your money?

Like many, the incentive of the excess funds mixed with sudden impulse spending are hard to ignore. For most of the savings (in particular online savings accounts), you need a commitment to withdraw the funds, reducing the chance that you withdraw funds unnecessarily.

If you believe you can effectively control the amount of money you withdraw and save, then a Cash Management Account, which allows money withdrawn at your fingertips any time, would be best suited for your lifestyle .......
