Describe the various hardware components and provide examples.
Hardware consists of electronic components and related gadgetry that input, process, output, and store data according to instructions encoded in computer programs or software. Processing devices include the central processing unit (CPU), which is also called the brain of the computer. The CPU works in conjunction with main memory. The CPU reads data and instructions from memory, and then stores the results of computations in main memory. Main memory is also called RAM, which stands for random access memory. Storage hardware saves data and programs. Magnetic disk is the most common storage device, although optical disks such as CDs and DVDs are also popular. Thumb drives are small, portable storage devices that can be used to back up data and transfer it from one computer to another.
Which of the following hardware developments allow objects to connect to a network and share data with any other application, service, or device?
Internet of things (IoT)

PC virtualization
The process by which a personal computer hosts several different operating systems is known as ________.
PC virtualization
Define the terms personal computers, servers, and server farms.
Personal computers (PCs) are classic computing devices that are used by individuals. In the past, PCs were the primary computer used in business. Today, they are gradually being supplanted by tablets and other mobile devices. A server is a computer that is designed to support processing requests from many remote computers and users. A server is essentially a PC on steroids. A server differs from a PC principally because of what it does. A server farm is a collection of, typically, thousands of servers. Server farms are often placed in large truck trailers that hold 5,000 servers or more. Typically, a trailer has two large cables coming out of it; one is for power and the other is for data communications. The operator of the farm backs a trailer into a pre-prepared slab, plugs in the power and communications cables, and runs thousands of servers.
The cloud is defined as the elastic leasing of pooled computer resources over the Internet.
T
Describe the difference between volatile and nonvolatile memory.
The cache and main memory are volatile, meaning their contents are lost when power is off. Magnetic and optical disks are nonvolatile, meaning their contents survive when power is off. If you suddenly lose power, the contents of unsaved memory-say, documents that have been altered-will be lost.
