There are three main limits to primary storage of a computer:
1) Physical space
2) Cost
3) Addressable space
Lets address them in more detail
1) Physical Space: Currently traditional hard drives (sometimes called Platter based hard drives) can support 250-500Gigabit / square inch (Approximately 30-60 gigabytes / square inch) . The physically larger drives in desktop computers and servers have platters that are a little larger that 5 inches across for about 19-20 square inches of space for a proximately 1 Terabyte per platter. The ability to have 3 platters in a single full size drive is why you will see 3TB drives at the store. In laptops the smaller 3.5 inch across platters and only being able to support 1 or two platters in a single drive is why you only see 500GB for the slim 8.0mm height drives (only fit 1 platter) and 1TB for the larger 9.5mm height drives (can fit a second platter).
2) Cost: Several companies have developed technology that increase the data density in answer 1, however that technology is extremely expensive to create and would make the hard drives more expensive than any consumer is willing to pay. However as they figure out cheaper ways to make the denser drives, you will see the capacity continue to rise. (This is also why the new super fast Solid State hard drives are so small. They can make bigger drives, they would just cost too much)
3) Addressable space: This is the easiest of the three limits to over come. The change from 32bit to 64bit computing changed this limit from 2 Terabytes to 8 Exbibytes (an Exibyte is approximately a 1 followed by eighteen 0s). The physical limitations should not reach this any time soon.
What else can I help you with?
Why is it important to know how many system words will fit in a primary storage device on a computer?
It is important to know how many system words will fit in a primary storage device on a computer so you know how big of a storage unit you have. The more system words that will fit in a primary storage device, the more memory you have on your computer.
What are the difference between primary and secondary storage device?
Primary storage is usually the drive where the operating system is and the secondary storage is a additional drive for space. Usually, Windows names it's primary drive as C:\ and all it's following as other letters.
What is the difference between primary storage and secondary storage of computer system elaborate?
Primary storage, also known as main memory or RAM, is the computer's fast and temporary storage used for actively running programs and data that are in use. It is volatile, meaning it loses its data when the power is turned off. In contrast, secondary storage, such as hard drives and SSDs, provides long-term data retention and is non-volatile, retaining information even when the power is off. While primary storage is faster, secondary storage offers greater capacity and is essential for storing files, applications, and the operating system.
What do you understand by a memory of computer system?
Memory of computer system is the part of the computer's hardware that allows it to store information. It is classified into primary/main memory (RAM and ROM) and secondary storage (hard drives, CD drives etc.).
What is difference between primary storage secondary storage and offline storage?
Primary storage refers to the main memory of a computer, such as RAM, which is fast but temporary and volatile, meaning it loses data when power is off. Secondary storage, like hard drives and SSDs, is non-volatile and provides long-term data storage, retaining information even without power. Offline storage refers to any storage that is not directly accessible by the computer's operating system, such as external hard drives, USB drives, or magnetic tapes, which can be disconnected and used for backup or transfer purposes. In summary, primary storage is fast and temporary, secondary storage is slower but permanent, and offline storage is external and not directly connected to the system.
What is the purpose of data storage systems?
Data Storage systems can serve quite a number of various purposes. The most common use, and their primary function, is to store data. What is meant by this is that anything that is done on a computer that requires the computer to remember something is stored on the data storage system.
The greatest nonvolatile storage capacity in the computer system is found in the?
The greatest nonvolatile storage capacity in the computer system is usually found in secondary storage and mostly on the hard disk. RAM on the other hand represents the greatest volatile storage capacity on a computer.
What is the primary job that a computer performs?
1: Input Whatever is put into a computer system. 2: Process Manipulation a computer does to transform data into information 3. Storage Temporary or primary storage is the computer circuitry that temporarily holds data waiting to be processed. Permanent or secondary storage is the area in the computer where data or information is held permanently. 4: Output Anything that is output from the computer system, the results of processing. 5: Communication Extension capability: Data maybe input from afar, processed in a remote area, stored in different locations, or output in other places.
What are the six categories of hardware?
The six hardware components of a computer system are the central processing unit (CPU), primary storage, secondary storage, input devices, output devices, and the communication devices. The central unit of a computer is the CPU.
Distinguish between primary storage and secondary storage?
Primary storage, also known as main memory or internal memory, refers to the storage space in a computer that is directly accessible to the processor. Primary storage is typically used to store data and instructions that are currently being used or processed by the computer. Secondary storage, also known as external memory, refers to storage space that is not directly accessible to the processor, but is used to store data and instructions for longer periods of time. Secondary storage is typically used to store data that is not currently being used, but that needs to be kept for future reference. There are several key differences between primary storage and secondary storage: Speed: Primary storage is generally faster than secondary storage, as it is directly accessible to the processor. This means that the processor can access and retrieve data from primary storage more quickly than it can from secondary storage. Capacity: Primary storage is typically smaller in capacity than secondary storage. This is because primary storage is used to store data that is currently being used or processed, while secondary storage is used to store data that is not currently being used. Cost: Primary storage is typically more expensive than secondary storage, as it requires faster and more expensive memory chips. Volatility: Primary storage is generally volatile, meaning that it is lost when the power is turned off. In contrast, secondary storage is non-volatile, meaning that it retains data even when the power is turned off. Location: Primary storage is located inside the computer, while secondary storage is typically external to the computer and is connected to the computer through a port or interface.
How is the CPU linked to the primary storage and other devices in the computer system?
The CPU (processor?) handles all processes run on the computer, so in this case it processes and sends data to the hard drive (storage). You can think of the cpu a bit like your brain, in a way it controls everything else connected to the computer and is itself probably the most important computer component.
What is difference between primary device and primary storage device?
A primary device would be the main system drive. Almost always a hard drive. A primary storage device might just be another way to refer to it.
