Internal Memory
Cards in this deck (30)
- 1refers to the computer hardware integrated circuits that store information for immediate use in a computer.Computer Memory
- 2It is the memory that is directly accessible by the processor without requiring access to the computer's input-output channel.Internal Memory
- 3Two Types of Internal MemoryROM and RAM
- 4is a non-volatile memory, which means that its memory cells do not require a power supply to retain their bit value. The bit values can only be read and not written or modifiedRead-Only Memory (ROM)
- 5an entra memory that provides space for the CPU to read and write data. It is the fastest, but is also the most volatile memory.Random Access Memory (RAM)
- 6—Read Only Memory (ROM)
- 7Three Types of ROMProgrammable Read-Only Memory (PROM)
Erasable Programmable Read-Only Memory (EPROM)
Electrically Erasable Programmable Read-Only Memory (EEPROM) - 8is a computer memory chip that can be programmed once after it is created. Once it is programmed, the information written is permanent and cannot be erased or deleted.Programmable Read-Only Memory (PROM)
- 9a form of computer memory that is erasable and reusable, and which retains its content even when the power is interrupted. It is generally employed for programs designed for repeated use.Erasable Programmable Read-Only Memory (EPROM)
- 10is the ROM memory that can be erased selectively and written multiple times. When a larger electrical voltage is applied, it can be repeatedly erased and reprogrammed.Electrically Erasable Programmable Read-Only Memory (EEPROM)
- 11Give the Advantages of ROMROM is more reliable than RAM.
Easy to test ROM Memory.
ROM is a non-volatile memory.
Stored data in ROM is Permanent.
ROM data cannot be changed.
ROM Memory is cheaper than RAM Memory.
ROM is static memory so does not need to refresh every time.
ROM Memory helps to boot the operating system ( OS ). - 12Give the Disadvantages of ROMROM is a slower type of Memory.
ROM Memory is capable of reading data only, cannot change the ROM data.
Once the data is stored in the ROM, you cannot modify, delete or overwrite the data in the ROM.
Unlike RAM, incorrectly erasing the ROM Memory contents will brick the memory.
Some Special types of ROM Memory allow the user to only rewrite contents. - 13CHARACTERISTICS AND FEATURES OF ROMROM Memory consumes low power.
ROM memory is not as expensive as RAM.
The simple interface of ROM compared to RAM.
The testing method of ROM Memory is very simple.
ROM is a non-volatile memory. Non-Volatile Means Permanent Data That Doesn't Get Deleted.
The data of the ROM is not deleted even after the computer shuts down suddenly.
ROM is a static memory that does not need to be refreshed frequently.
ROM Memory is capable of storing data for a long time permanently. - 14—Random Access Memory (RAM)
- 15Give the Two Types of RAMc. Dynamic Random Access Memory (DRAM)
b. Static Random Access Memory (SRAM) - 16It is made up of millions of very small capacitors. Each of these capacitors has a transistor to let energy in and out. Need to be refresh.Dynamic Random Access Memory (DRAM)
- 17is a type of RAM that holds data in a static form, that is, as long as the memory has power. It does not need to be refreshed.Static Random Access Memory (SRAM)
- 18Give the Types of DRAMRumbos DRAM
Asynchronous DRAM
Synchronous DRAM
Double Date Rate SDRAM - 19is an extension of a computer's main memory. It is an internal random-access memory (RAMs) that use semiconductor-based transistor circuits like the main memory. It holds a copy of only the most frequently used information or program codes stored in the main memoryCache
- 20refers to the group of latches that store a single character. It is the smallest and fastest memory in a computer. This is not accessible by instructions used internally for processor operationRegister
- 21is a type of computer storage media that stores data electronically and has no moving parts. It is 3 made from silicon microchips. For example, CompactFlash memory is commonly a solid-state non-volatile memory.Solid State Storage (SSS)
- 22GIVE THE TYPES OF DDR SDRAMDDR1 SDRAM
DDR2 SDRAM
DDR3 SDRAM
DDR4 SDRAM - 23GIVE THE ADVANTAGES OF RAMRAM is faster than secondary storage.
RAM can capably read and write any type of data.
RAM memory increases your computer speed.
The Central Processing Unit (CPU) reads any data faster because of RAM. - 24GiVE THE DISADVANTAGES OF RAMRAM is an expensive memory. It means costly.
RAM is slower than the CPU cache memory.
RAM memory has limited space for storing data.
RAM is volatile memory means, Stored data in RAM cannot be permanent. - 25FEATURES AND CHARACTERISTICS OF RAMRAM memory is capable of doing both operations like write and erase.
Adding more RAM helps to boost up your computer system speed and working performance.
RAM memory allows the CPU to access data faster so that the computer can complete an instruction quickly.
RAM is less expensive than SSD, but in comparison to performance, Ram completes any instruction from SSD quickly. - 26is a memory storage device for computers and electronics. It combines the advantages of ROM and RAM. It not only has the electrically erasable and programmable capability (EEPROM), but also can read data quickly without power loss (the advantage of Non- Volatile RAM).FLASH MEMORY (FLASH STORAGE)
- 27GIVE THE TWO KINDS OF FLASH STORAGENOR AND NAND
- 28is the older of the two and is physically larger. uses no shared components and can connect individual memory cells in parallel, enabling random access to data. Slower in erases and writes but fast on data reads. Tends to be used primarily in consumer and embedded devices for boot purposes and read-only applications for code storage.NOR
- 29is more expensive but has a reduced size and faster write speeds. It has more compact and has fewer bit lines, stringing together floating gate transistors to increase storage density. It is better suited to serial rather than random data accessNAND
