Physical Characteristics Of Computer Memory

When speaking of Computer memory, one must take into account features like: location, capacity, transfer units, access methods, enforcement, physical, physical characteristics and organization. The memory devices are located in the processor registers in the main memory of the internal memory and secondary memory from external memory. Its capacity is measured according to the memory cell, word size and the number of words. A memory cell is an electric circuit used to store a bit. The natural unit of memory organization is known as word size. Long common words are 8,16,32,64 and 128 bits. On the other side are the numbers of words formed Bytes- 8-bit and 4-bit Nible- formed. Example: A memory chip is specified 2K x 8. How many words can be stored on the chip? How much is the total number of bits that this chip can store? Solution: In real numbers 1k = 1024. Therefore: • 2K = 2 x 1024 = 2048 words. Each word is 8 bits (byte). Therefore: • 2048 x 8 = 16,384 bits.

They also have a drive, an external and internal transfer and an addressing unit. The internal is usually governed by the bandwidth of the bus and the number of bits that can be written or read simultaneously. In the outer data blocks which are larger than one word is sent. The

Among the physical types are: the semiconductor (Ram, Rom, Jump Drive), magnetic (disk, tape) and optical (CD, DVD). Among their physical characteristics are the descent, which refers to the loss of electric power when the switch is turned off. It is also classified as volatile, this term refers to whether memory can lose its contents by the lack of energy. It loses its volatile content, nonvolatile content retained. This is classified as erasable, this refers to whether the content of a memory can be changed or removed deliberately. Finally another of its features is the power consumption, this is the amount of energy needed to maintain its
