Unmanaged vs managed switch

Are You Using the Right Type of POE Switch?

When it comes to maintaining a network, businesses need to assess their network demands to determine whether they need to choose between unmanaged POE switches or managed POE switches.managed vs unmanaged switch infographic Unmanaged POE switches are relatively inexpensive and their fixed configuration makes it easy to install the ‘plug and play’ device.  That is not to say that unmanaged POE switches do not come with other hardware features.Unmanaged POE switches can offer a redundant power input, extended operating temperatures, and a nearly noise-free operation among other hardware features.Many network administrators with heftier network demands opt for managed POE switches. Many of them feature port-mirroring and with the help of a protocol analyzer, can monitor the activity of incoming traffic which facilitates troubleshooting. Managed POE switches also allow network administrators to monitor and prioritize traffic, set up VLANs, and program them through interfaces such as Telnet, SNMP, or console.If you're seeking to update your network, visit our website for a more thorough collection of PoE switches, Gigabit Switches, Managed Ethernet Switches and Certified Industrial Switches.  

What Visible WiFi Would Look Like

Visible Wi-FIWiFi is technology that we have all come to appreciate. We appreciate the availability of WiFi at our local coffee shop, at parks, public libraries and public network locations. But what if we could see the technology with the human eye? These images created by M. Browning Vogel depict what visible WiFi would look like.What is WiFi? Essentially, WiFi is a field of energy transmitted as waves. These waves have a distinct height and they travel at a distinct speed. Just like radios, cell phones and televisions, a wireless network uses radio waves. The distance between WiFi waves is shorter than radio waves, although it is longer than waves produced by microwaves. This provides WiFi from interruption by other signals.WiFi waves travel through space quickly as pulses or waves that are data encoded. By a freeze frame depiction, the pulses display six inches apart. Various objects, such as trees, can block the signal. This requires that various WiFi routers be placed in different positions in order to ensure that coverage is flawless. Utilizing multiple routers can create a field that extends across large expanses in order to transmit over different frequencies.WiFi routers that are fixed to lamp posts, buildings and other objects create a circular shape data field around the locations. These antennas produce an omnidirectional signal that extends in circular bands equally in various directions. The data transmitted over a band is divided into various sub-channels. The colors depicted in the images display such sub-channels.WiFi transmitters are antennas with a transmission protocol that separates frequency band into segments or channels. Data can be transmitted efficiently over each channel to send and receive even larger data quantities, faster. WiFi fields are typically in the shape of spheres or elliptical and roughly extend for 20 to 30 meters.Versa Technology is proud to offer comprehensive wireless solutions for any business or enterprise. The wireless access points available at Versa Technology are ideal for commercial use and are stable and reliable units.Versa Technology | Versatek's Ethernet Extenders | PoE Devices and more
network security

Network Security Management

Network security management includes various rules and procedures adopted by network administrators to ensure that unauthorized users do not obtain access. Security involves a host of policies that limit access. The process makes the network secure and protects and manages network operations. The basic form of network security provides users the ability to distribute a password or ID to individuals to provide access. Network administrators control and must determine the users who can access network data. These users are then provided a password or login ID to access information and programs in their control. Networks can be set as both private and open to the public depending on the network need. Network security also encompasses a wide range of both public and private networks that are utilized in various tasks, including at the job site for communications and business transactions.The process begins with authentication, which typically involves a username and password. A quick authentication process, such as authenticating a username or password, is commonly referred to as one-factor authentication. A two-factor authentication process typically refers to an item that users keep, such as a security device, token, card or phone. The last categorization, the three-factor authentication, involves a procedure such as a fingerprint or retina scan.Receive a Complementary ConsultationWhen users are authorized, network policies and access are managed by a firewall. The firewall operates efficiently to halt unauthorized users from accessing the network, but may not be as efficient to determine attacks by viruses or worms. Network administrators should consider anti-virus software to prevent such attacks.A network administrator must determine the network security management needs. Small businesses need only a standard security system while a large business or enterprise may require additional security resources to stop unauthorized users or attacks.Small businesses typically require a standard firewall and a basic system for threat management. Standard anti-virus software or anti-spyware program is also a good investment for small business networks. Administrators should also use a strong password and the highest security settings supported by wireless devices. Small business owners should consider changing the network’s default SSID name and disabling the SSID broadcast function since home users tend to not use this function.Medium sized businesses should enable MAC Address filtering in order to efficiently manage MAC devices on the home network that are connecting to the router along with other necessary security steps.A government network security system must include a strong proxy and firewall to prevent unauthorized access from both internally and externally. This network system must contain very strong anti-virus software and encryption. In addition, administrators must ensure that hardware is stored in areas that are secure. For government networks, users must implement a private network that is especially for network hosts, in order to keep that private network unseen from other users. Government systems should also contain web servers that are hosted in a DMZ and secure wireless range.Versa Technology is leader of innovative network solutions for small, medium sized and large businesses.
