memory

Memory Introduction: Memory is an important part of a computer system and is used to store data and program code. It can store information long-term or temporarily depending on the needs of the electronic device. Memory type: Memory is mainly divided into two categories: random access memory (RAM) and read-only memory (ROM). Random Access Memory (RAM): Dynamic Random Access Memory (DRAM): Memory cells store information through capacitors and need to be refreshed regularly.Static Random Access Memory (SRAM)....

Electronic Components Encyclopedia-Capacitor

Capacitor Introduction: A capacitor is an electronic component used to store electrical energy. It serves the purpose of temporarily storing charge in a circuit. A capacitor consists of two conductors (usually metal plates) separated by a layer of insulating material (dielectric). When a voltage is applied across a capacitor, an equal amount but opposite sign of charge accumulates on the conductor. How capacitors work: Capacitors work on the basis of electric fields. When a capacitor charges, an electric f....
