Flashcards do conjunto (15)
- 1What does RAM stand for?Random access memory
- 2Is it volatile or non-volatileVOLATILE
- 3How does RAM work?When a program is loaded, it is copied from from the hard disk or other secondary storage into the RAM. The CPU can now access the data and instructions for the program
- 4What does Volatile meanData stored is lost when it loses power
- 5What does ROM stand for?Read 0nly Memory
- 6What is ROM used for?It is often used within a computer system to store the boot sequence
- 7How does ROM work?RAM chips use transistors to hold a charge that represents data but require power to maintain it. By connecting transistors together in a specific way they can remember what they are storing.
- 8What does a GPU do?A graphics card is a separate processing unit used to render images. It is optimized to produce high-quality 3D graphics for games and films. The GPU is responsible for handling images and frees up the CPU to do all other tasks.
- 9Sound CardUsed to receive and give out complicated sounds. A soundcard is usually inside the computer connected to the motherboard. Hi-spec soundcards can be external and connected by FireWire or USB. Powerful external soundcards are used in music recording studios to process live music recordings.
- 10What is a motherboard?It is a circuit that connects the CPU to all the other hardware. Buses are circuits on the motherboard that connect the CPU to other components.
- 11All Da busesThe speed of a bus is measured in megahertz (MHz). The faster the bus, the faster data is communicated. The speed of the motherboard is defined by the bus speed.
- 12Bus speedBuses are limited by their width in bits. They are usually 8, 16 or 32-bits wide. This tells us how many bits can be sent by the bus at any one time, eg a 32-bit bus can send 32 bits at once.
- 13different types of busesThe bus that connects the CPU to the memory is called the front-side bus (FSB)CPU cores share Level 2 and Level 3 cache across the FSB. They will usually connect to Level 2 cache through the back-side bus (BSB). The BSB is much faster than the FSB.
- 14What is the power supplThe power supply unit is the piece of hardware that's used to convert the power provided from the outlet into usable power for the many parts inside the computer case.
- 15What is a heat sinkA heat sink is an electronic device that incorporates a fan to keep a hot component such as a processor cool.
