It depends on the camera. A lot of new digital cameras have about 16 megabytes of inbuilt memory, which can only hold about 5 pictures, so it is normally used just as a backup. A camcorder, however, usually has about 40 gigabytes of inbuilt memory.
Most of the new digital cameras use SD card for image storage
Digital Camera Cards are removable memory storage devices used with digital cameras.
Mostly SD cards or MMC cards.
Most digital cameras have settled on the SD/SDHC storage format, though some still use xD or MemoryCard.
Many digital cameras, such as DSLRs, mirrorless cameras, and compact point-and-shoot models, can store hundreds of images, depending on their storage capacity and the size of the images. Cameras that use SD (Secure Digital) memory cards can have varying capacities, with many modern cards offering 64GB, 128GB, or more, allowing for thousands of high-resolution photos. Additionally, cameras with built-in storage or those that support external storage options can also accommodate large numbers of images. Overall, most modern digital cameras are designed to handle extensive photo storage needs.

Digital cameras have number of advantages over traditional film cameras. Digital cameras can display images on a screen immediately after they have been taken. Also because of the advances on memory devices it is possible to store hundreds to thousands of images on a single small device, and deleting images to free storage space. Finally, digital cameras allow integration with modern digital systems (like cell phones) and photo transfer to and from computers.
