2 nibbles = 1 byte
1024 bytes = 1 kilobyte
1024 kilobytes = 1 megabyte
1024 megabytes = 1 gigabyte
1024 gigabytes = 1 terabyte.
The hard drive
There are 3 types of permanent storage, aka secondary storage, on a computer: # Hard Drive # CD # Floppy disk
Secondary Storage or Hard Drive
If you are asking what the largest storage component in a personal computer is, that would be the hard drive. The hard drive is a non volatile storage medium. Meaning it holds its data, even when the power is turned off.
A DVD holds 4.7 GB = 4,700,000,000 bytes. (Actually something exact like 4,700,372,992 bytes.) A kilobyte is 1000 bytes, so a DVD holds 4,700,000 kilobytes.
RAM
The system unit is the part of the computer that holds the motherboard, power supply and storage. The different types of system units are desktop, tower, mini-tower and notebook.
The Ram - Random Access Memory temporarily holds programs and data while the computer is on and allows the computer to access that information randomly.
Permanent storage device such as a hard drive.
Ah, backing storage and main memory are like two happy little trees in the vast landscape of computing. Main memory, also known as RAM, is like a painter's palette where the computer can quickly access and work with data. On the other hand, backing storage, like a sturdy easel, holds data for the long term, even when the computer is turned off. Both are essential for creating a beautiful digital masterpiece.
Long term storage in a computer, such as a hard drive or SSD, stores data for a longer period of time, while short term storage, like RAM, holds data temporarily for immediate use. Long term storage impacts the system's capacity for storing large amounts of data, while short term storage affects the speed at which the system can access and process data. Balancing the two types of storage is crucial for optimal performance and functionality of the computer system.
well sd cards hold about the same and are a fair bit smaller
