How is memory measured

It all starts with the units, not exactly like the different units we use in our real world. The bit is the smallest unit of measurement which has a binary value of 0 or 1. Computers are designed to manipulate bits in groups or combinations of a fixed size which, in technical jargons is known as words. You can take the advertisement for a broadband connection package into consideration to understand this.

If your connection comes advertised with 3. Furthermore, it would be expressed as 0. Because computers use the binary base two method which is unlike the decimal base ten method, a kilobyte KB contains 1, bytes, not 1, bytes as many might have mistakenly regarded so far.

So, 1 MB contains 1,, bytes or 1, kilobytes instead of 1,, bytes or 1, kilobytes. Similarly, 1 gigabyte contains 1, megabytes, or 1,,, bytes instead of 1, megabytes or 1,,, bytes. Hard drive manufacturing companies take a different route other than binary digits or its subsequent larger units. Using a decimal system, manufacturers define the space a particular hard drive comes with. But, the computer acknowledges only 9. A beginner would easily call it a sign of malfunction which is not.

The only thing that happens here is the different angles the memory is defined. A second approach is to use a range of tasks selected so as to tap different aspects of human memory. Such an approach is of considerably more theoretical interest, and is discussed in more detail by Eysenck this volume.

Its weaknesses are that theories of memory are still changing relatively quickly, and that mapping such results onto memory outside the laboratory is often complex. A third approach is to attempt a more direct measure of everyday memory. For example, if a broadband Internet connection is advertised with a download speed of 3. Bits and bit rates bits over time, as in bits per second [bps] are most commonly used to describe connection speeds, so pay particular attention when comparing Internet connection providers and services.
