How much memory is 1 tb?

User Avatar

Asked by Wiki User

1,024 gigabytesOn a hard drive, a terabyte, abbreviated TB, is 1012 = 1,000,000,000,000 bytes of information. That is 1,024 times a gigabyte (GB) or 1,048,576 times a megabyte (MB), which is a million million bytes.

Among other things, a computer often uses one byte of space, in memory or on disk or tape, to represent one character (such as "c" or "&").

To think practically how much information a terabyte of disk space holds, let's assume we're storing text from magazine pages on a computer that does use one byte per character. At an average 5,000 characters per page, 1TB of disk space could hold 220 million pages of text!

Remember when 3.5" floppy diskettes were all the rage ?

It will take 728,178 of those disks to equal the storage capacity of a 1,024 gigabyte hard drive.

How does a human memory work?

User Avatar

Asked by Wiki User

Compared to computer memory, human memory is not only more complex, but much more unpredictable. Unlike the popular notion that memories are "stored" intact in a specific location in the brain, they are actually fragments which may be spread over hundreds of physical areas. In addition to the storage of memories, there is the added complexity of retrieving them. Some scientists say that each time we make an attempt to recall a certain memory, the fragments have to be pieced back together into a whole. The unpredictability comes from which fragments, how they are recombined, and what picture they might make from one time to the next.

What comes after a TB?

User Avatar

Asked by Wiki User

PB or petabyte which is 1024TB or 1000TB depending what you are talking about.

I believe the question is on Hard disk Space, hence, it starts with a Byte (byte)

Kilobyte (KB) = 1024 Bytes

Megabyte (MB) = 1024 KB

Gigabyte (GB) = 1024 MB

Terabyte (TB) = 1024 GB

Petabyte (PB) = 1024 TB

Exabyte (EB) = 1024 PB

Zettabyte (ZB) = 1024 EB

Yottabyte (YB) = 1024 ZB

Keep multiplying by 1024 to get the next unit.

What are computer storage measurements such as megabytes?

User Avatar

Asked by Wiki User

Computer storage measurements such as megabytes (MB) are used to quantify the amount of digital data that can be stored on a device. One megabyte is approximately 1 million bytes of data. It is often used to measure file sizes, storage capacities, or data transfer rates in computing systems.

What is 'plastic memory and how is it found in clay terms?

User Avatar

Asked by Wiki User

Plastic memory refers to the characteristic of a material to retain its shape or form after being manipulated or stretched. In clay terms, plastic memory can be observed when clay retains its shape or position after being molded or sculpted by the artist. This property allows the clay to hold intricate details and maintain its structure throughout the drying and firing process.

You suspect that a power supply is faulty but you use a multimeter to measure its voltage output and find it to be acceptable Why is it still possible that the power supply may be faulty?

User Avatar

Asked by Wiki User

The voltage output may appear to be within acceptable range under no load conditions, but the power supply may fail under load. Additionally, there could be issues with the power supply related to its current or ripple that cannot be accurately measured with a multimeter alone. It is also possible that the power supply has intermittent faults that are not consistently present when measuring voltage output.

How many bits of information does a single cell of a memory chip on a 256MB PC2700 DDR module hold?

User Avatar

Asked by Wiki User

Edited: 10/02/09 12:32 AM PDT

The previous answer here said simply:

"8 bits"

....which might be correct for the rate of data transfer (per cell), but that doesn't answer the question!

The way I finally figured it:

A 256MB (mega BYTE) module has 8 cells, (or chips).

256/8 = 32MB per cell

To convert BYTES to BITS, multiply by 8; (8 BITS to a BYTE).

32MB (x8) = 256Mb (mega BITS) per cell.

To convert MEGA bits to BITS*:

*(when referring to data storage, as in this case...)

1Mb = 1048576 bits

Therefore, the cell being 256Mb = (256 x 1048576) =

268,435,456 bits per cell

Formula: (256 x 1024 x 1024)

How are typhoons measured?

User Avatar

Asked by Wiki User

Typhoons are measured using the Saffir-Simpson scale, which categorizes storms based on their sustained wind speeds. The scale ranges from Category 1 (74-95 mph) to Category 5 (157+ mph), with higher categories indicating greater intensity and potential damage. Typhoons are also monitored using other factors such as pressure and storm surge.
