Is memory card input or output?
USB flash drives and memory sticks, iPods, external hard drives and, to a certain extent, mobile phones can be regarded as both input and output, as well as storage devices. SD, Mini SD and Micro SD cards also come into this category.
Is Memory Card A output device?
Most auxiliary storage devices—as, for example, CD-ROM and DVD drives, flash memory drives, and external disk drives also double as input/output devices (see computer memory).
Is a RAM input or output or storage?
RAM—random access memory—straddles the line between peripheral and primary component; it is technically a storage peripheral, but is required for every major function of a modern computer and removing the RAM will effectively disable any modern machine.
Are headphones input output or storage?
Are headphones input or output devices? When headphones are connected to a computer (laptop, smartphone, etc), they receive information outputted from the computer. This means headphones are output devices.
How is the memory related to the CPU?
The memory is the storage area where all the inputs are stored before processing and the outputs are stored after processing of inputs. Many devices provide input to computer and a space is required to store and queue all these inputs, before they are processed by the CPU. This is because these inputs are to be processed one by one.
What are the functions of memory and output?
The memory serves as the space to store the instructions. If the output device is busy in producing an output, the other outputs are queued up in the memory.We would be discussing various types of memories and memory devices in the following pages of this chapter. We will also talk about the properties of these devices.
How are secondary memories accessed by the CPU?
These are used for storing data/information permanently. CPU directly does not access these memories, instead they are accessed via input-output routines. The contents of secondary memories are first transferred to the main memory, and then the CPU can access it. For example, disk, CD-ROM, DVD, etc.
How is the memory stored in a computer?
Computer memory is the storage space in the computer, where data is to be processed and instructions required for processing are stored. The memory is divided into large number of small parts called cells. Each location or cell has a unique address, which varies from zero to memory size minus one.
