Comprehension: Read the given passage and answer the questions that follow. Computer memory is the storage space in the computer, where data is to be processed and instructions required for processing are stored. Memory is divided into cells and each cell has a unique address. Memory is divided into three types namely, cache memory, primary/main memory, and secondary memory. Cache memory is a very high speed semiconductor memory and is placed between CPU and main memory. The parts of data and programs are transferred from the disk to cache memory by the operating system, from where the CPU can access them. Advantages of cache memory include faster and less access time when compared with main memory. And disadvantages include, it is limited in space and expensive. Primary memory holds only those data and instructions on which the computer is currently working. These memories are not as fast as registers. It is divided into two subcategories: RAM and ROM. Characteristics of this memory are it is faster than secondary memory, data is lost in case power is switched OFF and a computer cannot run without the primary memory. Secondary memory is also known as external memory or non-volatile. These are used for storing data/information permanently. CPU directly does not access these memories, instead they are accessed via input-output routines. Examples include hard disk, CD-ROM, DVD, etc. Characteristics of this memory include: these are magnetic and optical memories, are slower than primary memories and a computer may run without the secondary memory. It is known as the backup memory. Which of the following is a magnetic memory?
