There are a number of distinct types of VLANs used in modern networks. Some VLAN types are defined by traffic classes. Other types of VLANs are defined by the specific function that they serve.


A data VLAN is a VLAN that is configured to carry user-generated traffic. A VLAN carrying voice or management traffic would not be part of a data VLAN. It is common practice to separate voice and management traffic from data traffic. A data VLAN, is sometimes referred to as a user VLAN. Data VLANs are used to separate the network into groups of users or devices.

Default VLAN

All switch ports become a part of the default VLAN after the initial boot up of a switch loading the default configuration. Switch ports that participate in the default VLAN are part of the same broadcast domain. This allows any device connected to any switch port to communicate with other devices on other switch ports. The default VLAN for Cisco switches is VLAN 1. In the figure, the show vlan brief command was issued on a switch running the default configuration. Notice that all ports are assigned to VLAN 1 by default.

VLAN 1 has all the features of any VLAN, except it cannot be renamed or deleted. By default, all Layer 2 control traffic is associated with VLAN 1.

What is Computer Security and Information Security?

First of all Information security means protecting information and information systems from unauthorized access, use, modification, or destruction. The terms information security, computer security and information assurance are frequently used interchangeably. These fields are interrelated and share the common goals of protecting the confidentiality, integrity and availability of information.

Information security, sometimes shortened to infosec, is the practice of protecting information by mitigating information risks. It is part of information risk management.

With the introduction of the computer, the need for automated tools for protecting the files and other information stored on the computer became evident. This is especially the case for a shared system as like internet. Thus, computer security is the generic name for the collection of tools designed to protect data and to prevent hackers.

Computer Security rests on confidentiality, integrity and availability.

Confidentiality is the concealment of information or resources. Cryptography can be the better choice for maintaining the privacy of information, which traditionally is used to protect the secret messages. Similarly, the privacy of resources, i.e. resource hiding can be maintained by using proper firewalls. Confidentiality is sometimes called secrecy or privacy.

What is Networking?

This definition of networking focuses on the basic goals of networking computers: increased manageability, security, efficiency, and cost-effectiveness over non-networked systems. We could also focus on the different types of networks:

LOCAL AREA NETWORKS (LANs) – which can range from a few desktop workstations in a small office/home office (SOHO) to several thousand workstations and dozens of servers deployed throughout dozens of buildings on a university campus or in an industrial park;
WIDE AREA NETWORKS (WANs) – which might be a company’s head office linked to a few branch offices or an enterprise spanning several continents with hundreds of offices and subsidiaries;
THE INTERNET – the world’s largest network and the “network of networks”.
We could also focus on the networking architectures in which these types of networks can be implemented:

PEER-TO-PEER NETWORKING – which might be implemented in a workgroup consisting of computers running Microsoft Windows 98 or Windows 2000 Professional;
SERVER-BASED NETWORKING – which might be based on the domain model of Microsoft Windows NT, the domain trees and forests of Active Directory in Windows 2000, or another architecture such as Novell Directory Services (NDS) for Novell NetWare;
TERMINAL-BASED NETWORKING – which might be the traditional host-based mainframe environment; the UNIX X Windows environment; the terminal services of Windows NT 4, Server Enterprise Edition; Windows 2000 Advanced Server; or Citrix MetaFrame.

DHCP Use-Cases

Not every DHCP use case needs L7 visibility. For example detection of DHCP rogue server. DHCP rogue server is unauthorized server that also offers client’s IP addresses and other network parameters like default gateway and DNS server IP addresses. Such server represents not only operational but also security risks.

From operational point of view, clients may experience problems with network access or communicating with other hosts due to incorrect IP or gateway. From security point of view, DHCP rogue server can be used by attackers for various network attacks (man-in-the-middle, sniffing and reconnaissance attacks).

DHCP rogue server detection can be handled by both Flowmon Monitoring Center and Flowmon ADS. Let’s start with Flowmon ADS. Flowmon ADS is equipped with DHCPANOM detection method. This method automatically detects non-legitimate DCHP servers, reports and alerts on such event. Using learned behavior of network nodes, the method can also detect anomalies in DHCP traffic.

What Is Artificial Intelligence Marketing?

Artificial intelligence marketing solutions offer ways to bridge the gap between data science and execution. The process of sifting through and analyzing huge dumps of data was once an insurmountable process and is now not only feasible, but it’s actually easy.

Let’s think about all of the new technologies that have hit the market in the past year or so. We’ve all heard about the iPhone 7, Google’s driverless cars, Snapchat Glasses, and even Elon Musk’s ‘city on Mars’. What about marketing-specific technologies though?

What is Artificial Intelligence Marketing?
Artificial intelligence marketing (AI Marketing) is a method of leveraging customer data and AI concepts like machine learning to anticipate your customer’s next move and improve the customer journey.

Different types of Printers?

It prints characters as combination of dots. Dot matrix printers are the most popular among serial printers. These have a matrix of pins on the print head of the printer which form the character. The computer memory sends one character at a time to be printed by the printer. There is a carbon between the pins & the paper. The words get printed on the paper when the pin strikes the carbon. There are generally 24 pins.

Laser Printer is a type of printer that utilizes a laser beam to produce an image on a drum. The light of the laser alters the electrical charge on the drum wherever it hits. The drum is then rolled through a reservoir of toner, which is picked up by the charged portions of the drum. Finally, the toner is transferred to the paper through a combination of heat and pressure.

This is also the way copy machines work. Because an entire page is transmitted to a drum before the toner is applied, laser printers are sometimes called page printers. There are two other types of page printers that fall under the category of laser printers even though they do not use lasers at all. One uses an array of LEDs to expose the drum and the other uses LCDs. Once the drum is charged, however, they both operate like a real laser printer. One of the chief characteristics of laser printers is their resolution – how many dots per inch (dpi) they lay down.

The available resolutions range from 300 dpi at the low end to 1,200 dpi at the high end. In addition to text, laser printers are very adept at printing graphics, so you need significant amounts of memory in the printer to print high-resolution graphics. To print a full-page graphic at 300 dpi, for example, you need at least 1 MB (megabyte) of printer RAM. For a 600 dpi graphic, you need at least 4 MB RAM.

Because laser printers are non-impact printers, they are much quieter than dotmatrix or daisy-wheel printers. They are also relatively fast, although not as fast as some dot-matrix or daisy-wheel printers. The speed of laser printers ranges from about 4 to 20 pages of text per minute (ppm). A typical rate of 6ppm is equivalent to about 40 characters per second (cps).

Best SD-WAN Software

SD-WAN is a hybrid application of software-defined networking (SDN) and wide area network (WAN) connectors. Companies use SD-WAN to link enterprise networks across large geographic areas. Businesses can connect remote offices and employees to securely deliver applications and information. These products eliminate a fair amount of hardware and service cost required to connect services through the cloud. The tools secure internet connections between end users and cloud-based applications. Many also provide virtualization features to enhance security even more through virtual private networks (VPN). These tools can also improve the quality and security of communications tools like voice over internet protocol (VoIP), web conferencing, and audio conferencing software solutions.

Know more about the MPLS advantages.

SD-WAN solutions are related to a lot of other IT infrastructure software, but have a unique set of characteristics and uses that set them apart. These dynamic tools fulfil a range of network security, application optimization, and IT administration needs.

To qualify for inclusion in the SD-WAN category, a product must:

Support multiple WAN connectors
Ability to support VPNs, firewalls, or web gateways
Link SDN and WAN connectors
Sync networks across long distances

What is SD-WAN and why do you need it?

To understand the importance of connectivity, let us imagine a day without it. Internet and phone lines are down. Your employees cannot access their mail; your offices cannot make or receive any calls; everyone from the CEO to the middle manager is left twiddling their thumbs as all their cloud hosted data and files are unavailable AND most importantly all your customer-facing applications are offline, turning away innumerable present and potential customers!

That reliable and highly available connectivity (Internet and telephony) is the lifeblood of the business world is irrefutable. In the present hyper-competitive scenario, organizations are increasingly turning to the latest technologies to achieve the best connectivity solutions at the most affordable prices. SD – WAN (Software defined – Wide Area Network) is the newest innovation to optimize WAN technology for faster, flexible and cheaper business connectivity.

SD – WAN explained
Enterprises have been relying on WAN networks to connect their branch offices; to ensure uninterrupted connectivity to remote locations they had to invest heavily in WAN infrastructure and bear the resulting maintenance costs. SD – WAN changed the landscape completely, allowing enterprises to only pay for the functionalities they require with their entire CAPEX investment amounting to small routers.
