Anatomy of a Website Address

It's natural to begin with www. when you think of a website and to end with .com/.org/.net. Web addresses are everywhere. But what does it all mean and why is it important? You're about to find out.

"Web Address" is the layman's term for the technical term URL, which stands for Universal Resource Locator.

Let's use the URL of this online document as an example:

http:// www. infopathways .com /documents/WhitePapers/ web-address-makeup.pdf

http:// stands for "Hyper Text Transfer Protocol". http:// tells the computer to transfer a webpage (hypertext) from the internet to your computer. Now a days, you do not need to type "http://" before the rest of your web address because computers assume it. However, it is often necessary to create a properly working hyperlink (a clickable link on a webpage or in a digital document). You may also see https://, which represents a secure, encrypted webpage, often for sites that contain and/or collect confidential or sensitive data.

www. stands for "World Wide Web", and is also abbreviated as WWW or W3, and is often referred to as the "Web". Do not confuse the World Wide Web with the "Internet", as they are not the same. Internet is a global system of interconnected computer networks. The Web is made up of text documents hyperlinked together and is just a part of the Internet. The WWW denotes the subdomain. This is normally considered the default of a web site, but can be one of several subdomains for a site. Not every subdomain in a URL has to be "www". Subdomains are the third level domains that can be used to organize your web site content. In products.yoursite.com "products" is a subdomain within "yoursite.com". Subdomains can use the same design/layout as your primary domain, or it may be completely different.

infopathways in this instance represents a unique Domain Name used for one website. Every website has to have a registered Domain Name. Often the name chosen will represent the company, the product, the service, and/or location in some way.

.com (commercial) is the most common "Top Level Domain"; other common TLDs include.org (non-profits),.edu (educational),.gov (government), and.net (network). By top level, we mean it is at the highest level in the hierarchical Domain Name System of the Internet.

/documents/WhitePapers/ represent folder levels within our website's Root Folder (aka: the main folder holding all of the web files that make up the website... pages, images, documents, css, and other code). By looking at the full URL, you can begin to visualize the file structure of the website. In this instance, "WhitePaper" is a folder inside of "documents" which is a folder inside the main Root Folder.

web-address-makeup.pdf represents our final destination, the page or file we are looking at. This is the file name of the page or document. In this instance, we are looking at a PDF (Portable Document Format) File. You may often see that the home page of a website has a file name of index.htm, index.html, index.asp, etc. All represent a file type; HTML is the most common and stands for "Hyper Text Markup Language", which is the name of the type of code used to build the web page. Today, there are various web-languages that make up the final code of a webpage.

How will this knowledge benefit you?

Many of these elements, though good to understand, may not impact the way you surf the web. However, there are important facts to reinforce:

When dealing with money online (banking, credit card or PayPal purchases, etc.), it is extremely important that the site read https ://. That "s" could mean the difference between a secure transfer of money or a scam artist taking you for all you've got.

You also need to be cautious of spam emails. Many a time, an email may look legit - they ask you to click the link to reset your password or to log into your account. Look at the web address very carefully before you enter any data. For example, banks should never email you out of the blue to reset your password or to have you log into your account to check something. Again, these are often from scam artists looking to collect your sensitive data and deplete your account. If anything looks suspicious, such as the grammar of the email, the graphics, or if the web address is spelled incorrectly, get out and disregard the email.

The Fabric Lining for Your Cloud Computing

The cloud is still an airy place that many are hesitant to ascend to. But no one can deny the huge growth in successful cloud computing in the past few years. It offers companies more freedom at less cost, and will soon be the most popular way to do business. However, with this jump into the cloud, traditional Ethernet is no longer the best solution. Many who use virtualization and cloud computing are switching to a new technology called Ethernet fabric.

In traditional Ethernet, a data center will have a group of switches to accommodate the high number of ports needed. Generally, the network is organized with some switches at the top of racks, some in the middle and some at the ends. They are all connected which forms a hierarchical Ethernet tree of sorts, and allows for traffic flow only on a north south axis. For two decades, there has been a three layer design with an access layer at the bottom, an aggregation layer in the middle, and a core layer topping the tree. Routing is only happening in the core layer, so to talk to a server on a different part of the network, you would have to travel up through the three layers and then back down again. Adding on server clusters will allow some traffic move east to west, but this branching out of the tree create more latency and restricts the bandwidth. On top of this, each switch has to process it's own information and be configured individually, which takes extra time.

With Ethernet fabric, you will find a simpler way to have better performance, and higher levels of availability and utilization. Basically, it is a flat, double network, self-healing fabric which is designed to work beyond the three layer limitations or traditional Ethernet. It doesn't use a spanning tree to stop the occurrence of loops and uses every single self-forming inter switch link to insure the shortest path is travelled. The self healing comes into play when a link becomes unavailable -- all other traffic on all other inter switch links in the fabric continue. The fabric is also flexible and can be designed in any format to fit the needs of your workload. Along the same vein, it is elastic and can efficiently scale up or down as needed. With advanced Ethernet fabric. you can managed the system from the domain rather than the device, and you can make decisions based on policy instead of repetitive procedures. The fabric with the addition of virtualization-specific enhancements will make VM automation within the network and IT automation a breeze.

Brocade is one of the leading producers in Ethernet fabric and have recently helped a Belgian media company, called De Persgroep, to upgrade and better manage its datacenter networking. Using an Ethernet fabric and Brocade's VDX 6720 switches, they were able to eliminate the need for a jumble of network wiring to a massive switch, add to the number of physical network ports, open the company's capacity for growth, and severely reduce bottlenecks.

Credentials and Experience in the IT Sector

As with any career path or profession, the IT industry's ranks of professionals are riddled with different expertise levels, college degrees, doctorates and certificates, each designed to readily define and assess just what a particular individual is capable of, professionally.

Given the diverse mix of disciplines, technical knowledge and duties expected from IT personnel, the areas of software, hardware and network infrastructure understanding has made the setting up of such industry markers a necessity, one which works for organization leaders and individual IT experts, in helping each other note what one is really skilled with and knowledgeable about.

But as with any career path or profession, the old "credentials VS experience" standard is also prevalent in the IT industry, with different organizations and entities having their say over which is more valuable - credentials or actual field work experience.

Though no clear cut answer can be given to such a conundrum, the weight of certain certificates, matched with ample work experience, have proven to be effective in pointing out true professionals from the rest, with the Cisco Certified Internetwork Expert (CCIE) certificate being one of the world's most respected.

The Cisco Certified Internetwork Expert Certificate

The CCIE Certification Standard is essentially designed to validate the actual skills and professional capacities of IT professionals, specifically targeting the key disciplines involved in managed network services.

Ascribed to be the highest certification standard awarded to qualified personnel, the standard is known for its comprehensive and extensive evaluation of network management skills, delving into the areas of security, network storage and data retrieval standards, service provider operations and more.

Qualifiers for the certificate are not required any prerequisites to qualify, only that their theoretic and field knowledge be at expert-level to readily pass and fulfill the validations and testing tools involved in getting the certificate.

Even the number of years an IT expert has under his or her belt isn't exactly an "issue", but as the overall IT landscape has proven, years' of experience and technical know how have proven to be important in passing the CCIE certificate's qualifier exams and assessments.

With less than 30,000 CCIE Certificate holders in the world, to say that getting a CCIE Certificate is easy would be an understatement, given the fact that theoretical knowledge on the rudiments and dynamics involved in managed network services isn't enough to really help qualifiers pass the certification's standards.

To some extent, the CCIE Certificate comes to combine the ideal that is experience AND technical knowledge, all in one.

I'm part of the management and development team at Presidential Training, one of the fastest growing CCIE Training providers out there. With a competitive set of training tools and services, you can be assured that our price to technology ratio is one of the most generous in the market today.

Cisco Router Configuration Command Line Interface (CLI) Modes

You can learn the different Router CLI configuration modes and their specifications here. This article will help you to passing your Cisco certification exams. Generally the lower end Cisco Routers uses different commands than the mid to upper range routers. The commands we are using on different Cisco Routers are almost the same, but there are always a few variations to these commands depending on the interfaces your Cisco Router has, IOS version, and the type of WAN protocols they support.

User Exec Mode:

This is the first mode you'll see on a Cisco Router is user exec mode. This is also the default mode when you are connected the Router using Telnet. You can't write or add to a configuration in this mode, but you can run quite a few show commands. This is a good mode to have users in who need to see the configuration, but shouldn't be allowed to change it.

The user exec mode prompt will look like this:

Cisco-Router>

Privilege or Enable Mode:

This mode has two names, the official one being privileged exec mode. It's more commonly referred to as enable mode, since "enable" is what you type to get into this mode. Now you got complete access privileges of Cisco device but this mode gives you more options for show and other commands, but you still can't configure anything.

Router>enable

Router#

Cisco Router Setup Mode:

Cisco Router will go to the setup mode if it is brand new or with default condition. After completing the booting process, Cisco Router will prompt in setup mode for initial configuration dialogue if there is no configuration in the memory. Already configured Cisco Router will not prompt setup mode directly. You can also enter into the Router setup mode any time by using setup command.

The Cisco Router setup mode commands are as follows:

Router # setup

System Configuration Dialog Continue with configuration dialog? [Yes/no]: Y

At any point you may enter a question mark "?" for help

Use ctrl-c to abort the configuration dialog at any prompt

Default settings are in square brackets "[ ]"

Basic management setup configures only enough connectivity for management of the Router, extended setup will ask you to configure each interface on the Router.

Would you like to enter basic management setup? [Yes/no] n

Global Configuration Mode:

To configure the Cisco Router, you must have to enter the global mode. To enter into this mode, issue the configure terminal or config t command from the privileged EXEC mode. All the configurations are done in this mode, and you can also issue a show command like in privilege exec mode by using Do command.

This mode we can call as Global mode or Global configuration mode

Router#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

Interface Mode:

To configure any interface, you have to enter the interface's configuration mode. To enter into this mode, issue the interface command from the global configuration mode. You can go back to the privileged EXEC mode by pressing CTRL+Z or issue an END command. To exit from this mode, issue the EXIT command, and you'll be moved to the global configuration mode. You can also use show commands with DO command here.

Router(config)#interface serial0

Router(config-if)#

Sub Interface Configuration Mode:

To configure any logical interfaces on Cisco Router, you have to enter the sub interface's configuration mode. To enter into this, issue the interface command from the global configuration mode with sub or logical interface number.

Router(config)#interface FastEthernet 0/0.1

Router(config-subif)#

Router Configuration Mode:

To configure a Router protocol, you have to enter a specific Routing protocol command in global configuration mode. If want to execute a privileged EXEC commands such as the show command, you can execute using DO command. You can go back to the privileged EXEC mode by pressing CTRL+Z or with END command. To exit from this mode, issue the exit command, and you'll be moved to the global configuration mode.

Router(config)#router rip

Router(config-router)#exit

Router(config)#

Line Configuration Mode:

To configure authentication to access the router using the console port or remotely, you have to enter the configuration mode of the specific line(s). To enter into this, issue the line command from the global configuration mode or other configuration mode. If you wish to execute a privileged EXEC command such as the show command, you can precede it by the DO command. You can go back to the privileged EXEC mode by pressing CTRL+Z or with END command. To exit from this mode, issue the exit command, and you'll be moved to the global configuration mode.

The prompt config-line indicates that you're in line configuration mode.

Router#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#line console 0

Router(config-line)#password cisco

Router(config-line)#login

Router(config-line)#line vty 0 4

Router(config-line)#password cisco

Router(config-line)#login

Notice that you do not have to exit one interface mode to go to another one. Let's say that you've configured your VTY lines and now want to put an IP address on your Ethernet interface. You don't have to go out with ctrl-z and then start again - you can go straight to interface config mode from line config mode. Just make sure you see the prompt change.

What Is System Progressive Protection?

The answer to this question is a fake anti-virus. Unfortunately, this is the only simple answer regarding the malicious System Progressive Protection which schemers invented to steal your money. Of course, the guile is not as straightforward and many Windows users fail to understand or catch the scheme at the right time. Regardless, there is hope as the rogue can and should be defeated. Below you will find essential information regarding System Progressive Protection removal.

Cyber criminals who stand behind the deceitful rogue have enough experience to propagate their creation successfully and efficiently. This is because they are also responsible for releasing Live Security Platinum, Smart Fortress 2012 and other rogue security tool clones. Funnily enough, the latest three infections have the same interfaces, produce the same symptoms and can be removed using the same methods. In the world where people cared about their digital security, the repetitiveness could stop schemers. However, this is not the world we live in.

It has been discovered that the malicious System Progressive Protection can remove access to the Task Manager, disable the Registry Editor and make it impossible to run many of the system's executable files. This not only can restrict the infection's removal, but can also reinforce the illusion that your PC is under an attack of malicious viruses, worms and other infections. This is presented by a completely bogus rogue's scanner which simply lists non-existent threats to grab your attention. Additionally, you may notice fake security notifications popping from the Task Bar, slower PC performance and Internet connection issues. All of this will be concentrated to convince you to purchase the full version of System Progressive Protection. If you do not want your private data leaked and money wasted, you need to ignore such deceitful recommendations.

None of the mentioned symptoms should be linked to infections other than System Progressive Protection. This fake anti-spyware tool is the main danger running on your personal computer, which is why it is essential to delete it before proceeding with any other tasks. You can commence with a special activation key which will disable all symptoms and will allow you to install automatic removal tools or delete System Progressive Protection manually.

The removal of the rogue may become an extremely complicated and time-consuming task, if you proceed manually. Using automatic removal software to delete System Progressive Protection is much more appropriate, because it can also produce requisite computer's protection.

Early Installation of Anti-Malware Can Minimize Damage by the Search Redirect Virus

Most of us tend to address problems as they come. Typically, we wait till the last possible minute to take care of a problem that we may have seen coming a while ago.
