  1. Computer Components Brittany Qualls 4th period

  2. Motherboard- is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, providing connectors for other peripherals.

  3. Power Supply-converts mains AC to low-voltage regulated DC power for the internal components of the computer

  4. Drive Brays - a standard-sized area for adding hardware to a computer.

  5. Central Processing Unit- the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system.

  6. RAM( random access memory )- is a form of computer data storage.

  7. Hard Drive -is a device for storing and retrieving digital information, primarily computer data.

  8. Fan- any fan inside, or attached to, a computer case used for active cooling, and may refer to fans that draw cooler air into the case from the outside, expel warm air from inside, or move air across a heat sink to cool a particular component.

  9. Expansion Card- in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus.

  10. Ports/Connectors- an application-specific or process-specific software construct serving as a communications endpoint in a computer's host operating system.

  11. A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem. An important class of computer operations on some computing platforms is the accepting of input from human operators and the output of results formatted for human consumption. The interface between the computer and the human operator is known as the user interface.

  12. Conventionally a computer consists of some form of memory, at least one element that carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on the information that is stored. Peripheral devices allow information to be entered from an external source, and allow the results of operations to be sent out. • A computer's processing unit executes series of instructions that make it read, manipulate and then store data. Conditional instructions change the sequence of instructions as a function of the current state of the machine or its environment.
