Computing Device - answer A computing device is an electronic machine that uses binary data to automatically perform calculations. PC - answer A personal computer, or PC, is a computing device designed to be used by one person at a time. These computing devices are found in offices, schools, and homes. PCs are used to run commercial software applications, desktop computer - answer A desktop computer is a computing device designed to be placed on or near a user's desk. Its size and its need to be plugged in to a power source mean it typically needs to be placed where it will be used and not be moved. All-in-One Desktop Computers - answer Some computers have the monitor and the computing components all in one physical device and are hence referred to as all-in-one computers Laptop - answer laptop is a complete computer system that is small, compact, lightweight, and portable. All laptops have specialized hardware designed especially for use in a smaller portable system, use standard operating systems, can run on battery or alternating current (AC) power Servers - answer network computer that shares resources with and responds to requests from computers, devices, and other servers on the network. Servers provide centralized access and storage for resources that can include applications, files, printers, and other hardware as well as services, such as email. Supercomputer - answer fastest and the most expensive computer among all types of computers Mainframe - answer large computer that might serve a large organization. It is used to process and store information for many users at once. Motherboard - answer motherboard is the personal computer component that acts as the backbone for the entire computer system. CPU - answer computer chip where most of the computing calculations take place Power supply - answer internal computer component that converts line voltage AC power from an electrical outlet to the low-voltage direct current (DC) power needed by system components RAM - answer type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. volatile memory. Byte - answer One character (a letter, number, space, or punctuation mark). A byte consists of 8 bits. Kilobyte (KB) - answer 1,024 bytes or 8,192 bits constitute 1 KB Megabyte (MB, Meg, or M) - answer 1,048,576 bytes or 1,024 KB constitute 1 MB. Gigabyte (GB) - answer 1,073,741,824 bytes or 1,024 MB constitute 1 GB. Terabyte (TB) - answer 1,099,511,627,776 bytes or 1,024 GB constitute 1 TB Dual in-line memory modules (DIMMs) - answer found in many systems, and they have a 64-bit data path. DIMMs generally have 16 or 32 chips per module. Small outline dual in-line memory modules - answer SODIMMs are most often seen in laptops, small networking devices (such as routers), and PCs with smaller system boards. They have either 32- or 64-bit data paths. Half the size of DIMM hard drive - answer generally non-removable disks. Almost all computers use hard disk drives to store data. Hard disks store data digitally on circular platters. Storage capacity of hard disk drives is expressed in gigabytes (GBs) and terabytes (TBs) Solid State Drive - answer Solid state storage uses non-volatile memory to emulate mechanical storage devices. USB devices that are commonly known as jump drives or thumb drives; flash memory cards; and secure digital Optical drive - answer personal computer storage devices, such as CDs, DVDs, or Blu-ray™ discs, that store data optically rather than magnetically. Video Cards - answer Video cards typically have their own bank of memory to improve the rate at which the images on screen can be updated. Video cards can have a variety of connectors on them for connecting video display devices. Some of the video adapters include VGA, DVI, and HDMI. Audio card - answer An audio card typically includes ports to connect speakers, a microphone, and headphones. Network Card - answer A network adapter allows your computer to connect to other computers over a wired or wireless connection. Expansion Card - answer expansion card is a printed circuit board that you install into a slot on the computer's system board to expand the functionality of the computer Modem - answer allows your computer to connect to other computers and the Internet by using an analog phone line. Liquid cooling system - answer liquid cooling system inside the case. These cooling systems use tubes filled with a coolant, connected to a radiator, and a pump to circulate the liquid coolant through the inside of your computer case Heat Sinks - answer metal, usually formed into ridges, and installed on components. The heat sink transfers the heated air from the component to the fan (or liquid cooling system), which then moves the heated air out of the computer case, keeping the inside of the case and the components cooler. Port - answer hardware interface that you can use to connect devices to a computer Serial Connection - answer is a personal computer connection that transfers data one bit at a time over a single wire. Serial connections support two-way communications and were typically used for devices such as fax cards or external modems
