A computer network is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet. Network devices that originate‚ route and terminate the data are called network nodes.[1] Nodes can include hostssuch as servers and personal computers‚ as well as networking hardware. Two devices are said to be networked when a process in one

Wired and Wireless‚ What’s the Difference? The main difference between a wired and wireless data communication infrastructure is the existence of physical cabling. The same or similar techniques are employed for both types of data communication infrastructure in terms of the core elements of essential network services. The basic difference between a wired and a wireless network is self-explanatory. A wired network uses wires to communicate whereas a wireless network uses radio waves. Another difference

Benefits of Network video surveillance What is an Analog Video Security System? Cameras on a modern analog CCTV system send their video over co-axil cabling back to a digital video recorder (DVR). Most modern DVRs are a network device‚ and as such can be accessed remotely from the LAN‚ or with the proper configuration‚ from across a WAN or the internet. Video is kept on hard drives‚ typically on a FIFO basis so there is always a rolling video archive of the past X number of days. What is an

Project management is the discipline of planning‚ organizing‚ motivating‚ and controlling resources to achieve specific goals. A project is a temporary endeavor with a defined beginning and end (usually time-constrained‚ and often constrained by funding or deliverables)‚[1] undertaken to meet unique goals and objectives‚[2] typically to bring about beneficial change or added value. The temporary nature of projects stands in contrast with business as usual (or operations)‚[3] which are repetitive

Everyone building a network must face this question at some point: fiber or copper wiring? For a usual home network or even a big office either one will suffice but what is the best option for you or your company. You have to take cost‚ distance of cabling‚ and bandwidth and speed into consideration when making this choice. Copper: a traditional copper wiring for a network certainly seems much cheaper on the surface. Copper wiring itself is dirt cheap at least comparatively on the surface‚ but you

more appropriate in single-mode fiber because of its narrow spectrum. Laser transmitters are also used in Laser level finders. Laser level measures the level of the ground and returns the data. LEDs would be more efficient is multimode fiber optic cabling because it has a broader spectrum than single-mode. LEDs are used in television remote controls to transmit a signal.
