Network Cards and Network Controllers
(551 companies)
Network cards and network controllers are expansion boards inserted into computers that allow them to connect to a network.
Signal Conditioners
(941 companies)
...is mainly used as an impedance matching device. Isolation amplifiers are designed specifically to isolate high DC levels from the data acquisition device while passing the relatively small AC or differential signal. The inputs and outputs...
Vector Network Analyzers
(68 companies)
Vector network analyzers (VNA) measure the complex transmission and reflection characteristics of two-port devices in the frequency domain.
Network Firewalls
(110 companies)
Network firewalls protect computer networks against unauthorized use or attack. They permit or deny access to private network devices and applications, and represent an important part of an organization's overall security policy. Firewalls may be software applications, hardware devices (such as routers), or a combination of both. They include turnkey products that are relatively easy to install as well as complex, multi-layer installations that require the expertise of a certified network administrator.
Inductors, Coils, and Chokes
(1,025 companies)
Inductors coils and chokes are passive components that are designed to resist changes in current and store energy in the form of a magnetic field.
Scalar Network Analyzers
(49 companies)
Scalar network analyzers measure the amplitude portion of scattering or S-parameters, reflection and transmission coefficients between the incident and reflection waves that describe a device’s behavior under linear conditions at the microwave frequency range.
Network Modems
(429 companies)
Network modems (modulators-demodulators) are devices or programs that allow computers to transmit data over telephone lines. They convert digital computer data to analog sound waves and then demodulate the carrier signals to decode the transmitted information.
Network Appliances
(53 companies)
Network appliances are inexpensive personal computers (PC) or computer boards that provide Internet access and promote network security. They lack many of the features of fully-equipped PCs, however.
Wireless Network Components
(339 companies)
Wireless network components are used to build or replace worn out devices within a wireless network.
Network Servers
(677 companies)
Network servers control and manage network resources such as files, printers, users, groups, etc.
Network Routers
(486 companies)
Network routers are protocol-dependent devices that connect subnetworks, or that break down a large network into smaller subnetworks.
Network Gateways
(443 companies)
Network gateways interconnect networks with different, incompatible communication protocols. They perform a Layer-7 protocol-conversion to translate one set of protocols into another (for example, from TCP/IP to SNA or from TCP/IP to X.25).
Network Cables
(703 companies)
Network cables are used in the transmission of data across networks. Choices include Fibre Channel, FireWire or IEEE 1394, GPIB, serial, parallel, patch, SCSI, Ethernet and USB.
Network Switches
(667 companies)
Network switches connect network devices to host computers and allow a large number of devices to share a limited number of ports. They increase network capacity and speed by examining and filtering data packets. Switches also regenerate forwarded packets, reducing collision rates and permitting the use of additional nodes.
Network Hubs
(263 companies)
Network hubs provide a central location for attaching wires to workstations. Often, these hardware devices include a network switch that controls how and where data is forwarded.
