Question: Which Of The Following Is Not A Sequential Storage Device?

How many types of storage devices are there?

two typesThere are two types of storage devices used with computers: a primary storage device, such as RAM, and a secondary storage device, such as a hard drive.

Secondary storage can be removable, internal, or external..

Which of the following devices provides sequential and direct type of data?

“Sequential access must begin at the beginning and access each element in order, one after the other. Direct access allows the access of any element directly by locating it by its index number or address. … Magnetic tape has only sequential access, but CDs had direct access.

Which is an example of sequential access device?

A common example of sequential access is with a tape drive, where the device must move the tape’s ribbon forward or backward to reach the desired information.

Is hard disk a sequential access device?

Hard drives, etc., everything in fact uses sequential access for recording the data, but the chipset that controls the data stored and access control is called the DMA controller. … But again, all data is sequentially written and read, regardless of the media.

What are primary and secondary storage devices?

Primary memory usually refers to Random Access Memory (RAM), while secondary storage refers to devices such as hard disk drives, solid state drives, removable “USB” drives, CDs, and DVDs.

What are five common storage devices?

Which of the following devices is a storage device?

CDs, DVDs, and Blu-Ray disks are used for a lot more than just playing music and videos—they also act as storage devices, and collectively they’re known as optical storage devices or optical disk media.

What are two advantages of the sequential type file?

Sequential access has advantages when you access information in the same order all the time. Also is faster than random access. On the other hand, random access file has the advantage that you can search through it and find the data you need more easily (using indexing for example).

What is the difference between sequential access and random access?

The terms random access and sequential access are often used to describe data files. A random-access data file enables you to read or writeinformation anywhere in the file. In a sequential-access file, you can only read and write information sequentially, starting from the beginning of the file.

Is ROM a primary storage device?

The two main types of primary storage are ROM, which is non-volatile , and RAM, which is volatile . Non-volatile memory keeps its contents even when the computer is switched off. Volatile memory loses its contents when power is lost.

Is hard disk a primary storage device?

A computer’s internal hard drive is often considered a primary storage device, while external hard drives and other external media are considered secondary storage devices. … In this case, primary storage typically refers to random access memory (RAM), while secondary storage refers to the computer’s internal hard drive.

Which of the following is not a storage device?

Answer. A plotter is not a storage device. Explanation: A ‘plotter’ is an external hardware device like a printer used with a computer to ‘print vector graphics’.

Which is not a primary storage device?

Random Access Memory (RAM) and cache are both examples of a primary storage device. The image shows three different types of storage for computer data. Primary storage’s key differences from the others are that it is directly accessible by the CPU, it is volatile, and it is non-removable.

Is ROM sequential access memory?

The access time depends on the location of the data. Applications of this sequential memory access are magnetic tapes, magnetic disk and optical memories. In this method, any location of the memory can be accessed randomly like accessing in Array. … Applications of this random memory access are RAM and ROM.

Which of the following is sequential access storage device?

Browse Encyclopedia Magnetic tape is the common sequential access storage device.

What is the meaning of storage devices?

A computer storage device is any type of hardware that stores data. The computer’s primary hard drive stores the operating system, applications, and files and folders for users of the computer. … While the hard drive is the most ubiquitous of all storage devices, several other types are common as well.

What is sequential access method?

Sequential access is a term describing a group of elements (such as data in a memory array or a disk file or on magnetic tape data storage) being accessed in a predetermined, ordered sequence. … Sequential access is sometimes the only way of accessing the data, for example if it is on a tape.
