More About Pre-Owned Cisco

Cisco Systems is the largest manufacturer of networking systems in the world! Cisco network equipment dominates the router and switch market and sets the standards for all other companies. With Cisco network equipment, you can easily upgrade and adapt to new network configurations. Cisco gear is compatible with most transport and access methods.

Define: Cisco Routers

"A router is a computer networking device that buffers and forwards data packets across an internetwork toward their destinations, through a process known as routing. Routing occurs at layer 3 (the Network layer e.g. IP) of the OSI seven-layer protocol stack" (Wikipedia). Used and refurbished Cisco routers can give you a competitive edge at keeping your operational costs down.

Define: Cisco Switches

A switch is an important part of a network, because it is a device that segments networks into different subnets (or - splits the bandwidth). Segmenting the network into different subnets keeps one network from overloading with traffic. "The network switch, packet switch (or just switch plays an integral part in the vast majority of current Ethernet local area networks or LANs. Mid-to-large sized LANs contain a number of linked managed switches... A switch is a data link layer networking device. Switches perform transparent bridging (connection of multiple network segments with forwarding based on MAC addresses. Typical port speeds on an Ethernet switch are 10, 100, 1000 or 10000 megabits per second (Mbit/s), and half or full-duplex..." (Wikipedia).

Define: Cisco Broadband

"Broadband is a transmission medium capable of supporting a wide range of frequencies, typically from audio up to video frequencies. It can carry multiple signals by dividing the total capacity of the medium into multiple, independent bandwidth channels, where each channel operates only on a specific range of frequencies" (Verio). Broadband networks use analog signaling over a wide range of frequencies and many cable companies offer high-speed Internet access over broadband systems.

Define: Cisco PIX Firewalls & VPN Security

"A firewall is a system which limits network access between two or more networks. Normally, a firewall is deployed between a trusted, protected private network and an untrusted public network. A firewall might grant or revoke access based on: user authentication, source and destination network addresses, network protocol, time of day, network service, or any combination of these. It might be implemented as an application level firewall or a packet level firewall. It might also implement a content filter, such as a virus wall" (M-Tech Identity Management). Cisco ASA Adaptive Security Appliances are used to secure today's private networks. Make sure to visit our section on Cisco Firewalls.

Define: Cisco VPNs

"VPN stands for Virtual Private Network. This creates a secure “tunnel” between the points within the VPN. Only devices with the correct "key" will be able to work within the VPN. The VPN network can be within a company LAN (Local Area Network), but different sites can also be connected over the Internet in a secure way. One common use for VPN is for connecting a remote computer to the corporate network, via e.g. a direct phone line or via the Internet" (Axis Communications).

Define: Cisco VoIPs

Voice over IP (VoIP) defines a way to carry voice calls over an IP network including the digitization and packetization of the voice streams. IP Telephony utilizes the VoIP standards to create a telephony system where higher level features such as advanced call routing, voice mail, contact centers, etc., can be utilized" (Cisco). "Voice over Internet Protocol, also called VoIP, IP Telephony, Internet Telephony, Broadband telephony, Broadband Phone and Voice over Broadband is the routing of voice conversations over the Internet or through any other IP-based network" (Wikipedia).

Define: Cisco Phones

"IP telephony provides a way for you to extend consistent communication services to all your employees, whether they are in main campus locations, at branch offices, or working remotely, or are mobile. IP telephony transmits voice communications over a network using open-standards-based Internet Protocol" (Cisco).

Define: Cisco Wireless

Wireless communication is generally considered to be a branch of telecommunications. The term wireless technology is generally used for mobile IT equipment. It encompasses cellular telephones, personal digital assistant (PDAs), and wireless networking. Other examples of wireless technology include GPS units, garage door openers and or garage doors, wireless computer mice and keyboards, satellite television and cordless telephones" (Wikipedia).
