What are bytes and gigabytes?

and...

What's the difference between memory and a hard drive?

Thanks in advance!

bytes are basically one character. gigabytes are 1,000,000,000 of those. if u make a .txt file its bytesize should be the same as its character count typically.hard drives store data longer term and is most useful when not continually being access. memory referred to as ram is Random Access Memory that is typically used for storing data that is used a lot, overwritten a lot. When you installed a program on your computer it takes up hard drive space. When you start the program to run it the programs code is loaded into ram and any information the program is accessing is usually stored in the ram.

bytes are units of storage in a computer. 8 bits (a bit is the smalled unit of storage, it is either a 1 or a 0 in binary) make up a byte.It goes:bit->byte->Kilobyte->Megabyte->Gigabyte->Terrabyte and so on.Memory and a harddrive are similar in that each stores data, but memory is volatile. When the power is turned off, all information in it is lost. Hard Drives are non-volatile, they retain all of their data when the computer loses power. Memory is super fast compared to hard drvies, and is used to store information that is currently being used by the system.

A byte is commonly used as a unit of storage measurement in computers, regardless of the type of data being stored. One gigabyte is one billion of bytes, one megabyte is one million bytes.Memory (or RAM) is a computer chip which is capable to store a certain amount of bytes. A harddrive is a device which also stores data on a number of magnetic disks. Both memory and harddrive store data, however they differ in the way how the data is accessed.

There are 8 bits in a byte. 1 Kilobyte has 1024 bytes. 1 Megabyte has 1024 Kilobytes. 1 Gigabyte has 1024 Megabytes. So this is all just units of measurements when you are referring to computer memory. Compare it it to units for measuring weight ... miligram, gram, kilogram, etc...Memory is a general term for something that stores data...that could be just temporary storage or permanent storage. For example RAM (Random Access Memory) is temporary storage that your computer uses to store various instructions and commands from the microprocessor and other components while your computer is running but when you turn the computer off that memory is erased. A hard drive on the other hand stores data permanently until it is erased by a computer user, when you turn your computer off and on the data on the hard drive still remains there.
