Switch for midium to large business

Switch

The network switch, or hub, plays an important role in most modern Ethernet local area networks (LANs). Mid-to-large sized LANs contain a number of linked managed switches. Small office/home office (SOHO) applications typically use a single switch, or an all-purpose converged device such as a gateway to access small office/home broadband services such as DSL or cable internet.

Firewall for network

Firewall

A firewall is a device designed to permit or deny network transmissions based upon a set of rules and is frequently used to protect networks from unauthorized access while permitting legitimate communications to pass through. Many personal computer operating systems include software-based irewalls to protect against threats from the public Internet.

Wireless Access Point for network

Wireless Access Point

A wireless access point (WAP) is a device that allows wireless devices to connect to a wired network using Wi-Fi, Bluetooth or related standards. The WAP usually connects to a router (via a wired network), and can relay data between the wireless devices (such as computers or printers) and wired devices on the network.

Wireless router for network

Wireless Router

A wireless network router is a device that performs the functions of a router but also includes the functions of a wireless access point and a network switch. They are commonly used to allow access to the Internet or a computer network without the need for a cabled connection. It can function in a wired LAN (local area network), a wireless only LAN (WLAN), or a mixed wired/wireless network.

Server for business

Server

A server is a high-end computer, or series of computers, that link other computers or electronic devices together. They often provide essential services across a network, either to private users inside a large organization or to public users via the internet.

Workstation for business

Workstation

A workstation is a high-end computer designed for technical or scientific applications. Historically, workstations had offered higher performance than desktop computers, especially with respect to CPU and graphics, memory capacity and multitasking capability. They are optimized for the visualization and manipulation of different types of complex data such as 3D mechanical design, engineering simulation, animation and rendering of images, and mathematical plots.

Printer for business

Printer

A MFP printer is a convenient replacement for printers, scanners and fax machines. For high volume printing a dedicated laser printer will stand up to heavy use. Large format printers are easy way to produce large documents in-house. Solid ink printer can save money on high volume colour printing. For home use a simple inkjet printer is generally sufficient.
