内存：
随机存取存储器 (RAM) 用于读取和写入。它是主内存的一部分，用于存储正在运行的应用程序(程序)和程序执行操作的数据。它主要有两种类型：动态RAM(或DRAM)和静态RAM(或SRAM)。
摄像头：
内容可寻址存储器 (CAM) 也称为关联存储器，其中用户提供数据字，关联存储器搜索其整个存储器，如果找到数据字，则返回该数据字所在的地址列表。
下面根据它们的特性给出差异表：
| S.NO | RAM Memory | Associative Memory(CAM) |
|---|---|---|
| 1. | RAM stands for Random Access Memory. | It stands for Content Addressable Memory. |
| 2. | In RAM, the user supplies a memory address and RAM returns data word stored at the address. | In associative memory, the user supplies data word and associative memory searches its entire memory. |
| 3. | The price of RAM is low as compared to Associative memory. | It is expensive than RAM. |
| 4. | It is used to store running applications(programs) and program’s data for performing operation. | It is widely used in database management system. |
| 5. | This is suitable for algorithm based search via PRAM. PRAM stands for Parallel-RAM. | This is suitable for parallel search. |
| 6. | If the data word is found, RAM returns the data word. | If the data word is found, It returns the list of addresses where that data word was located. |
