Which of the following devices is a storage device?
Hard drive – An internal hard drive is the main storage device in a computer.
An external hard drive is also known as removable hard drive..
Which of the following is not an example of 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’.
What are the benefits of accessing files in random access mode?
In summary, there are 3 main advantages to random files:Random files allow you to directly access any record.Random files are usually smaller than sequential files.Random file streams can move data in both directions.
What are the 10 storage devices?

What is direct access and sequential access?
The process of searching the entire movie is called sequential access, because information is read in a particular order or sequence. If you can get to the record without following any sequence, this is called direct access.
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.
What are two advantages of the random access type file?
Advantages of Random file organization.Records are quickly accessed (i.e. there is fast access to records).Files are easily updated (i.e. adding, deleting, and amending the records is easily achieved).The method does not require the use of indexes, hence saving space.Transactions do not need to be sorted before being updated.
What are the different types of direct access storage devices?
Direct Access Storage Devices (DASDs)CD-ROM (compact disk read-only memory)DVD.WORM (write-once read-many)
Which of the following 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.
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 are examples of storage device?
Rotating optical storage devices, such as CD and DVD drives, have even longer access times. Other examples of secondary storage technologies include USB flash drives, floppy disks, magnetic tape, paper tape, punched cards, and RAM disks.
Which is sequential access storage device?
In computing, sequential access memory (SAM) is a class of data storage devices that read stored data in a sequence. This is in contrast to random access memory (RAM) where data can be accessed in any order. Sequential access devices are usually a form of magnetic storage or optical storage.
What 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.
Which of the following is not a sequential storage device?
Magnetic tape has only sequential access, but CDs had direct access.
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.
What are 4 types of storage devices?
Types of storage devicesPrimary Storage: Random Access Memory (RAM) Random Access Memory, or RAM, is the primary storage of a computer. … Secondary Storage: Hard Disk Drives (HDD) & Solid-State Drives (SSD) … Hard Disk Drives (HDD) … Solid-State Drives (SSD) … External HDDs and SSDs. … Flash memory devices. … Optical Storage Devices. … Floppy Disks.
What is the difference between random access and sequential access quizlet?
What is the difference between Sequential Access and Random Access? Comparing sequential versus random disk operations helps to assess systems efficiency. Sequential access is the type of memory mostly used for permanent storage, whereas, random access memory is used for temporary storage.
What is meant by sequential access?
Sequential access means that a group of elements (e.g. data in a memory array or a disk file or on magnetic tape data storage) is accessed in a predetermined, ordered sequence. … It may also be the access method of choice, for example if we simply want to process a sequence of data elements in order.
What is a sequential process?
Definition. Sequential processing refers to the mental process of integrating and understanding stimuli in a particular, serial order. Both the perception of stimuli in sequence and the subsequent production of information in a specific arrangement fall under successive processing.
What are the two types of RAM?
Types. The two widely used forms of modern RAM are static RAM (SRAM) and dynamic RAM (DRAM). In SRAM, a bit of data is stored using the state of a six-transistor memory cell, typically using six MOSFETs (metal-oxide-semiconductor field-effect transistors).
What is a sequential list?
If you make a list of things you need to do, starting with number 1 and continuing until all your tasks are accounted for, then you’ve made a sequential list.
