1. The Booth algorithm is used for performing multiplication of two signed numbers in binary form. It reduces the number of operations required for multiplication, making it more efficient.
2. Rambus memory is a type of dynamic random-access memory (DRAM) technology. It was developed by Rambus Inc. and is known for its high-speed data transfer capabilities. It uses high-speed signaling technology to achieve fast data transmission between the memory controller and the memory module.
3. Cache memory is a small and fast memory component that stores frequently accessed data and instructions. It is located closer to the CPU than the main memory, allowing for quicker retrieval of information. The use of cache memory helps to improve the overall performance of a computer system.
4. Virtual memory is a technique used by operating systems to provide an illusion of having more physical memory than the actual amount available. It allows programs to run even if the total memory required exceeds the physical memory capacity. Data and instructions are temporarily stored in the hard disk in a portion called the swap file.
5. ROM (Read-Only Memory) is a type of non-volatile memory that retains its data even when the power is turned off. It contains pre-programmed instructions or data that cannot be modified or erased under normal operating conditions. Various types of ROM include:
- Mask ROM: The instructions or data are physically etched onto the ROM chip during its manufacturing process and cannot be changed.
- PROM (Programmable Read-Only Memory): User-programmable ROM where data can be written only once.
- EPROM (Erasable Programmable Read-Only Memory): Similar to PROM but can be erased and reprogrammed using ultraviolet light.
- EEPROM (Electrically Erasable Programmable Read-Only Memory): Can be erased and reprogrammed electrically, without the need for ultraviolet light.
