About Cisco
Cisco's approach to quality can be condensed down to one phrase: "ensuring our customer success". The information contained in this section will help you to gain a better understanding of Cisco's Business Management System, which allows us to accomplish that success. Cisco's Business Management System is made up of two parts; the Quality Management System and the Environmental Management System.
Cisco Fun Facts
Cisco Systems, Inc. is an American multinational technology conglomerate headquartered in San Jose, California, in the center of Silicon Valley, that develops, manufactures and sells networking hardware, telecommunications equipment and other high-technology services and products. Through its numerous acquired subsidiaries, such as OpenDNS, WebEx, Jabber and Jasper, Cisco specializes into specific tech markets, such as Internet of Things (IoT), domain security and energy management.
Cisco is the largest networking company in the world. The stock was added to the Dow Jones Industrial Average on June 8, 2009, and is also included in the S&P 500 Index, the Russell 1000 Index, NASDAQ-100 Index and the Russell 1000 Growth Stock Index.
Cisco Systems was founded in December 1984 by Leonard Bosack and Sandy Lerner, two Stanford University computer scientists, who pioneered the concept of a local area network (LAN) being used to connect geographically disparate computers over a multiprotocol router system. By the time the company went public in 1990, when it was listed on the NASDAQ, Cisco had a market capitalization of $224 million. Cisco was the most valuable company in the world by 2000, with a more than $500 billion market capitalization

Network Switch Buying Guide
Connect Multiple Devices to a Network and Route Data to Designated Devices
What is a network switch and what does it do?
A network switch connects devices to a local area network (LAN) and allows the devices to communicate over the network. For example, you can connect computers, printers and servers to the same network switch and route data between them. Unlike an Ethernet hub, which transmits the same data through every output, a network switch sends data only to the devices designated to receive it. This improves the efficiency and potential throughput of the network.
Are there different types of network switches?
There are two main types of network switches, unmanaged and managed. The essential difference is the capability to configure the operation of a managed switch to customize and optimize network traffic for specific applications.
Unmanaged Switches
- Offer plug-and-play functionality
- Switch operation cannot be modified
- CompSource offers desktop and rack-mount unmanaged switches
Managed Switches
- Provide the ability to manage, prioritize and monitor LAN traffic
- Offer one or more ways to modify switch operation
- CompSource offers smart managed switches that feature an RJ45 console port and command line interface (CLI)
Where do you place network switches?
Network switches are usually placed on a desk or table, mounted on a wall, or mounted in a rack. CompSource offers unmanaged desktop switches (with metal or plastic housing) and both unmanaged and managed rack-mount switches with metal housing and a built-in PDU (Gigabit Ethernet Switch PDU Combos).
What is a Gigabit Ethernet Switch PDU Combo?
CompSource offers an exclusive line of unmanaged and managed Gigabit Ethernet switches that have Power over Ethernet (PoE).
Factors to Consider
Does your application require a managed switch?
If your application involves controlling network traffic, you will need the features of a managed switch. The following are some examples of tasks that require a managed switch:
- Controlling access between departments within your LAN
- Running many bandwidth-intensive applications simultaneously
- Giving important data greater priority in your LAN
- Improving the performance of a busy network
- Implementing VoIP, wireless LANs or other advanced services
How many devices do you need to connect to your network?
Make sure you select a switch with enough Gigabit (10/100/1000 Mbps) Ethernet ports for the devices you want to connect to your network. If you think you'll add more devices in the future, choose a switch that will give your network room to grow.
Do you need to connect multiple network switches?
If you plan to connect multiple network switches, look for models with SFP uplink ports (also known as Mini-GBIC ports). SFP uplink ports are connection points for SFP (small form-factor pluggable) modules that allow the switch to uplink to other switches using optical fiber cabling.
Power over Ethernet (PoE) uses existing network cables to power connected devices, such as VoIP phones, wireless access points and surveillance cameras. If you need this functionality, look for a switch with Gigabit Ethernet ports that support PoE. Make sure the power per port (in watts) and the total power budget of the PoE ports meet the needs of your electronic devices.

I called your company in a panic! I needed 40 Dell Axim extended batteries. Jeff answered the phone. He was so helpful! He jumped through hoops to get me what I needed. I know that he made numerous phone calls to various distributors to get enough to ship to me. The other issue was that I had to have them by today! I called your company Wednesday. I received my batteries this morning. Great Job, Jeff!!!! brussellMore Reviews
