Memory - RAM and its types
RAM is a type of volatile memory that is used for temporary storage. It allows data to be accessed randomly in any order. There are different types of RAM such as static RAM, dynamic RAM, SDRAM, and DDR SDRAM. RAM is part of a memory hierarchy that includes processor registers, cache memory levels L1-L3, main memory, and virtual memory. Future RAM technologies aim to provide memory that is smaller, faster, and cheaper than current memory chips.
Computer Memory
Main memory consists of storage locations that can be uniquely addressed and hold data in the form of words. The two main types of main memory are RAM and ROM. RAM is volatile and used to store running programs and data, while ROM is non-volatile and used for firmware like the bootstrap loader. Cache memory and processor registers provide even faster temporary storage than main memory to improve system performance. Virtual memory uses the hard disk as an extension of main memory when RAM is insufficient. The closer the storage is to the processor, the faster the access speed.
Introduction to Motherboard
This presentation provides an overview of motherboard components and functions. It describes the main components including the CPU socket, memory slots, chipset, BIOS, expansion slots, and input/output ports. It explains that the motherboard connects the central processing unit and other internal components to enable communication within the computer. Form factors like ATX and microATX determine the motherboard size and compatibility. Selecting a motherboard involves considering the CPU, case, expansion needs and warranty.
TYPES OF MEMORIES AND STORAGE DEVICE AND COMPUTER
Memory refers to the physical devices used to store programs and data in a computer. Main memory is divided into RAM and ROM. RAM is read-write memory that uses transistors and capacitors to store each bit. There are two types of RAM: static RAM which does not need refreshing but is expensive, and dynamic RAM which needs refreshing but has higher density. ROM is read-only and stores permanent instructions. There are also programmable ROMs like PROM, EPROM, and EEPROM that can be programmed and erased in different ways. Caches and secondary storage supplement main memory and improve performance. Common secondary storage devices include magnetic disks, tapes and optical discs.
COMPUTER MEMORY : TYPES & FUNCTIONS
Memory is essential for computers and comes in three main types: primary, cache, and secondary. Primary memory (RAM) is directly accessible by the CPU and comes in volatile forms like DRAM and SRAM. Cache memory improves access speed and can be L1/L2 caches. Secondary memory (hard disks, DVDs) provides large storage but is slower to access. The document discusses these memory types in detail along with their technologies and principles.
ROM(Read Only Memory )
ROM(Read Only Memory ) is computer memory on which data has been prerecorded. Once data has been written onto a ROM chip, it cannot be removed and can only be read.
