In a a fieldwork experiment the scientist experimentally examines an intervention in the real world. A scientist might choose a fieldwork instead of laboratory experiment in order to answer for example some <span>behavioral questions. Often the best observations are made in the field.</span>
<span>A field experiment is more suitable for investigating a wider range of factors affecting the overall result.</span>
Answer:
A storage area network (SAN) is a dedicated high-speed network or subnetwork that interconnects and presents shared pools of storage devices to multiple servers.
The availability and accessibility of storage are critical concerns for enterprise computing. Traditional direct-attached disk deployments within individual servers can be a simple and inexpensive option for many enterprise applications, but the disks -- and the vital data those disks contain -- are tied to the physical server across a dedicated interface, such as SAS. Modern enterprise computing often demands a much higher level of organization, flexibility and control. These needs drove the evolution of the storage area network (SAN).
SAN technology addresses advanced enterprise storage demands by providing a separate, dedicated, highly scalable high-performance network designed to interconnect a multitude of servers to an array of storage devices. The storage can then be organized and managed as cohesive pools or tiers. A SAN enables an organization to treat storage as a single collective resource that can also be centrally replicated and protected, while additional technologies, such as data deduplication and RAID, can optimize storage capacity and vastly improve storage resilience -- compared to traditional direct-attached storage (DAS).
SAN architecture
A storage area network consists of a fabric layer, host layer and storage layer.
Answer:
Central processing unit (CPU)
Explanation:
A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user.
The central processing unit (CPU) is typically considered to be the brain of a computer system. It is the system unit where all of the processing and logical control of a computer system takes place.
Hence, the most important component in a computer is the central processing unit (CPU) because without it, it is practically impossible for the computer to run any software application or program.
Additionally, the component of the central processing unit (CPU) that controls the overall operation of a computer is the control unit. It comprises of circuitry that makes use of electrical signals to direct the operations of all parts of the computer system. Also, it instructs the input and output device (I/O devices) and the arithmetic logic unit on how to respond to informations sent to the processor.
