Cooking

The term "cooking" encompasses a vast range of methods, tools and combinations of ingredients to improve the flavour or digestibility of food. It usually requires the selection, measurement and combining of ingredients in an ordered procedure in an effort to achieve the desired result. Constraints on success comprise the variability of ingredients, ambient conditions, tools, and the skill of the individual cooking.
The diversity of cooking worldwide is a reflection of the myriad nutritional, aesthetic, agricultural, economic, cultural and religious considerations that impact upon it.Cooking require applying heat to a food which usually, though not always, chemically transforms it, thus changing its flavor, texture, appearance, and nutritional properties.Cooking proper, as different to roasting, requires the boiling of water in a container, and was practiced at least since the 10th millennium BC with the introduction of pottery. There is archaeological evidence of roasted foodstuffs at Homo erectus campsites dating from 420,000 years ago.

Web camera

A web camera is a real-time camera, whose images can be accessed using the World Wide Web, instant messaging, or a PC video calling application. The term web cam is also used to describe the low-resolution digital video cameras designed for such purposes, but which can also be used to record in a non-real-time fashion. Web-accessible cameras typically involve a digital camera which uploads images to a web server, either continuously or at regular intervals. This may be achieved by a camera attached to a PC, or by dedicated hardware. Videoconferencing cameras typically take the form of a small camera connected directly to a PC. Analog cameras are also sometimes used, connected to a video capture card and then directly or indirectly to the internet.

Network Monitoring

The term network monitoring describes the use of a system that always monitors a computer network for slow or failing systems and that notifies the network administrator in case of outages via email, pager or other alarms. It is a subset of the functions occupied in network management.

While an interruption detection system monitors a network for threats from the outside, a network monitoring system monitors the network for troubles due to overloaded and/or crashed servers, network connections or other devices.

Usually measured metrics are response time and availability (or uptime), although both consistency and reliability metrics are starting to increase popularity. Status request failures, such as when a connection cannot be established, it times-out, or the document or message cannot be retrieved, usually produce an action from the monitoring system. These actions vary: an alarm may be sent out to the resident (SMS, email etc) sysadmin, automatic failover systems may be activated to remove the disturbed server from duty until it can be repaired, etcetera. Monitoring the performance of a network uplink is also known as network traffic measurement, and more software is listed there.

Cream

Cream is a dairy product that is composed of the higher-butterfat layer skimmed from the top of milk before homogenization. In un-homogenized milk, over time, the lighter fat rises to the top. In the industrial manufacture of cream this process is accelerated by using centrifuges called "separators". In many countries, cream is sold in several grades depending on total butterfat content. Cream can be dried to a powder for shipment to distant markets.Cream produced by cows (particularly Jersey cattle) grazing on usual pasture often contains some natural carotenoid pigments derived from the plants they eat; this gives the cream a slight yellow tone, hence the name of the yellowish-white colour cream. Cream from cows fed indoors, on grain or grain-based pellets, is white.

Within these, there are many different types of motorcycles for many different purposes.Choppers,Cruisers,electric motorcycles,Mini bikes,Mopeds,Scooters etc are street motorcycle.Motocross,Supermotos,Dual-sports,Enduros are the off-road motorcycle.
A motorcycle is broadly defined by law in some countries for the purposes of registration, taxation or licensing riders as a two-wheel motor vehicle "fit to drive." Other countries distinguished between mopeds and other small bikes and the larger, more powerful vehicles.
