The current state of desktop computing has left the issue of desktop scalability

The current state of desktop computing has left the issue of desktop scalability in limbo in that many legacy desktops are Ethernet challenged in that they can only achieve speeds from 10 MB to 100 MB per second (Fast Ethernet). Many manufacturers are currently installing them in all new model desktop computers. The inclusion of gigabit speed Ethernet adapters has increased by leaps and bounds the switch to Server extension of the way we think about LAN and Wan networking. The uses of Gigabit Ethernet adapters have allowed many businesses to expand their infrastructures removing the bottlenecks of standard Ethernet connectivity. The combined use of Gigabit switching, category 6 or fiber cabling to the desktop has given IT enthusiasts a cause to smile. Previously cost was the overriding factor in the hesitation to bring gigabit speeds to the desktop. This barrier has been broken with the introduction of lower cost drivers, new protocols and hardware that is designed to fit the PCI bus of newer model computers. Manufacturers have made standard gigabit internal and expansion cards truly bringing fiber speeds from the switch to the desktop. Faster access times add up to reduced costs on bandwidth and less time in accessing server resources modern servers come with Gigabit Ethernet ports to allow fast link to switching resources. Computers using these adapters show a marked increase in access to applications, handling and resolution of graphical interfaces and increased access up time bordering on 99.5% on average.[citation needed] Currently Gigabit Ethernet adapters provide connectivity to network systems in the 1000BASE-T standard for Gigabit Ethernet over copper, Gigabit Ethernet speeds can be widely deployed at less expense using standard Category 5 cabling also in 1998 Gigabit Ethernet over fiber optic cable as IEEE 802.3z.[1]
[edit] Health effects of desktop computers
Carelessly-arranged computer screens and keyboard can lead to ergonomics problems such as eyestrain and repetitive strain injuries while using a keyboard for long periods. The height of a standard desktop is not recommended for keyboard use, and stacking the monitor on the case aggravates posture problems.
