In the modern 21st century world, almost all aspects of life and society have been connected through computer networks. Especially with the introduction of the internet to the world, networks have been the way to go, for almost everything concerning professional tasks. Networking is one of the key factors that have caused the phenomenon of globalization as well. Hence, with networking having this kind of impact on many aspects of our life in the modern world; it is important to look at how so much has become possible, with the utilization of networking hardware or peripherals.
Networking hardware refers to equipment which typically enables computers to network, includes hardware such as, routers, switches, access points, network interface cards and other hardware devices. With respect to the modern trend in these technologies, it is important to mention that the most common kind of hardware used today are copper based Ethernet adapters, which are included in many modern computer systems.
The importance and the integration of networking hardware in modern devices can be understood better, as these devices are also included in day to day utilities such as mobile phones, PDAs and even modern coffee machines.
A router is referred to a computer which has the ability to perform such tasks as routing and forwarding information with use of software and hardware. Routers are regarded to generally contain a specialized operating system, along with such devises as RAM, NVRAM, flash memory, and one or more processors.
Switches and Hubs
According to simple theoretical terms, switches are defined as devices which join multiple computers together, with better facilities offered than hubs. And hubs can be defined as, small, uncomplicated, economical devices that join multiple computers, with a lower or basic level of networking facilities.
A modem enables a computer to transmit data over long distances using a cable or telephone line. As computer data is in digital form, it needs to be converted for transmission over the cable/telephone line, which only carries analog waves. This task or conversion is facilitated by a modem.
This piece of networking hardware is one of the most essential pieces of equipment for any computer network, since it has the function of providing access between a computer and a network connection. When considering the theoretical aspects of network adapters, it is common to discuss the importance of another essential component, the network interface card or NIC. The term NIC refers to network adapter hardware in the form of a card.
Patch Cables - A patch cable connects two network devices
Ethernet Crossover Cables - A crossover cable directly connects two network devices of the same type to each other over an Ethernet. Crossover cables are useful for temporary networking of devices when a network router, switch or hub is not present.
Fiber Optic Cable - Fiber optic cables carry information using light pulses. These cables are typically designed for long distance networking use, although they are soon becoming popular for home use today.
