What are the limitation of secondary memory?
Disadvantages: 1. Due to their small size, they can easily be misplaced or lost. 2.It can even be infected by viruses.
What are the limitations of primary and secondary memory?
Primary memory devices are also relatively more costly to purchase and install in the computer. (ii) The main disadvantages of secondary memory are that it is located further away from the Central Processing Unit (CPU) and therefore, the speed at which data stored in secondary memory can be accessed is slower.
What are the main limitations of the primary storage of a computer system?
Due to its technological design to access data fast it’s is limited in storage space. Means it’s can store limited data. 2. It is VOLATILE in nature due to its circuit formed with registers it can able to hold data as long as it’s capacitors are charged.
What are the advantages and limitations of secondary memory?
Advantages include easy portability, faster read speeds, and greater durability, however storage capacity is considerably lower than magnetic disk storage. The capacity of optical drives is not as high as HDDs and the cloud, but costs have remained low, and they remain a viable option for secondary storage.
What are the secondary storage?
