How many bytes in one giga bytes?
In computer memory terms, one gigabyte = 1,073,741,824 bytes. In telecomunication terms, it is commonly referred to as 1,000,000,000 bytes. For most marketing reasons, it is shortened to mean 1,000,000,000 bytes, however this is slightly misleading.
How many bytes make up a Terabyte?
One tera byte is 1,099,511,627,776 (240) bytes, in traditional computer memory terms, or 1,000,000,000,000 (1012) bytes, in computer communications terms. Usage is sometimes confusing, because not everyone uses the same nomenclature.
What is memory leakage in terms of arrays?
leakage in arrays occur when you declare an array with big size and using only very few bytes.
How many bytes of memory is a 1Mx64 memory chip?
A 1Mx64-bit memory chip contains <1,048,576> , or <2^20> 64-bit Lwords. You could express this either in terms of MegaBits or MegaBytes. In Megabits, 64Mbits because 1Mx64 = 64Mbits and divide by 8 to get the answer in terms of bytes. You divide by 8 because there are 8 bits in 1 byte. So a 1Mx64-bit memory contains 8 Mbytes, or 64 Mbits. If the width had been 1Mx32-bit, you would have 32Mbits, and 4 Mbytes.
What is a PLC Memory?
Memory is the component that stores information, programs, and data in a PLC. See more..... projuktiponno The process of putting new information into a memory location is called writing. The process of retrieving information from a memory location is called reading. Types of Memory The common types of memory used in PLCs are Read Only Memory (ROM) and Random Access Memory (RAM). A ROM location can be read, but not written. ROM is used to store programs and data that should not be altered. For example, the PLC’s operating programs are stored in ROM. A RAM location can be read or written. This means the information stored in a RAM location can be retrieved and/or altered. Ladder logic programs are stored in RAM. When a new ladder logic program is loaded into a PLC’s memory, the old program that was stored in the same locations is over-written and essentially erased. The memory capacities of PLCs vary. Memory capacities are often expressed in terms of kilobytes (K). One byte is a group of 8 bits. One bit is a memory location that may store one binary number that has the value of either 1 or 0. (Binary numbers are addressed in Module 2). 1K memory means that there are 1024 bytes of RAM. 16K memory means there are 16 x 1024 =16384 bytes of RAM.
What is meant by GB data?
GB is acronym for gigabyte and is used to indicate storage capacity on a computer. A gigabyte is 2^30 bytes or 1,073,741,824 bytes. Note that disk manufacturers and memory chip manufacturers use different notations. Memory chips are precisely specified such that a 1 GB memory chip is guaranteed to provide storage for exactly 1,073,741,824 bytes. However, hard drives only give approximate storage capacities such that 1 GB only guarantees storage capacity for at least 10^9 bytes, or 1 billion bytes, which is the equivalent of a 0.93 GB memory chip. Technically, hard-drive manufacturers use the correct notation since the prefixes kilo-, mega- and giga- literally equate to some power-of-ten (10^3, 10^6 and 10^9 respectively). However, it is not possible to create a memory chip with exactly 10^3 bytes, it has to be an exact power-of-two (2^10, 2^20 and 2^30, respectively). The reason memory has to be an exact power-of-two stems from the way in which memory is addressed on a binary computer. In order to address 1000 bytes we'd need at least 10 bits in the range 0000000000 through 1111100111 (0 to 999 decimal) which means there are 24 invalid addresses in the range 1111101000 through 1111111111 (1000 to 1023 decimal). This over-complicates circuit design; it's much easier to make all bit patterns valid by adding on those missing 24 addresses thus giving us the full kilo-binary-byte capacity of 1024 bytes. Hard-drive manufacturers are less constrained in the way storage is addressed, because the addressing is subject to the operating system and the way in which the hard-drive is formatted. Typically, a hard-drive is divided up into addressable clusters which are themselves some power-of-two bytes in length, such as clusters of 512, 1024, 2048 or 4096 bytes. In an effort to avoid confusion, the terms kilo-binary-byte (KiB), mega-binary-byte (MiB) and giga-binary-byte (GiB) are used to indicate precise memory capacities while KB, MB and GB are used to indicate the more generalised hard disk capacities. However, these terms is not widely adopted. For instance, Windows operating systems use the term KB to mean 1024 bytes whether reporting memory capacity or hard drive capacity, hence a 300 GB hard-drive only has capacity for 279.4 GB of storage on Windows. But 279.4 GB is 300 billion bytes so, strictly-speaking, it is quite correct to call it a 300 gigabyte drive.
How is volts different from amps?
voltage is measured in terms of volts ; current is measured in terms of amps.........................................
How many bytes does a DVD hold?
when we're talking about DVD movies thinking in terms of how many bytes is pretty rediculous. a very short DVD quality movie will be measured at least in tens of mega-bytes (Mb). one megabyte is equal to 1,048,576 bytes. so, if you were, for instance, thinking in terms of how many bytes there were in a full-length DVD quality feature film then you would be talking about gigabytes(Gb). one Gb is equal to 1,073,741,824 bytes. you need between 1 and 3 gigs of space for a whole DVD worth of information.

Is SI the measured by grams?
SI is a system of measurement. A gram is one of the measurements defined by the SI. Having said that, I suppose the SI output, in terms of documentation related to standard units could have been measured in grams (kilograms, more likely). Although, nowadays, even that is likely to have been replaced by [mega]bytes.
