The ability to add fractions is a skill that many learn in elementary school and by the time they graduate from high school, seem to have forgotten because it is a skill used so sparsely. However, a quick mind refresh of the steps reveals that adding fractions is a straight forward process that requires three very basic steps. These steps, when combined with an understanding of what a fraction is makes solving addition of fractions very simple. To begin with, a fraction is a part of a whole. For example, Read More
Adding radicals can only be accomplished if there are like terms within the radical. That means that the number inside the radical (square root) has the be the same as the number inside the other radical. If that is not the case, the two cannot be added together. If it is the case, though, the two can be added together. Adding Radicals For the sake of this guide, we’ll use the equation: 2*sq(20x) + 3*sq(5x) Now, as can be seen from this equation, the numbers inside the radicals are different. Read More
The kilobit per second (kbps, or kbit/s, or kb/s) is a unit of measurement for the speed of data transfer. One kilobit per second is 1,000 bits per second. Other common multipliers follow the metric progression; Mbps (megabits per second), Gbps (gigabits per second), and Tbps (terabits per second). A bit is the smallest unit of data; it cannot be broken down into smaller units. A bit is either on or off; 0 or 1. For example, seven bits are required to communicate a single ASCII character.

A petabyte is a measurement unit that describes a piece of information that is equal to 1,000 terabytes or one quadrillion bytes of data. A single petabyte is equal to 1,000,000,000,000,000 bytes . When a petabyte describes computer memory, it is also used in reference to a corresponding power of 1024. The approved scientific symbol for the petabyte is PB. Pebibyte also describes a power of 1024 and is described through the symbol, PiB. Examples of Petabyte Use As computer data storage and network transmission capabilities continue to exceed the Read More
A yottabyte is an amount of information that equals one septillion bytes or one quadrillion gigabytes. This amount can also be measured as 1024 bytes. Yottabytes should not be confused with the term “yobibyte,” which is used to express a measurement that is much larger. Although yottabytes are currently an imaginary measurement, servers or even personal hard drives may use them some day. What Uses Yottabytes? Currently, no device in the world uses yottabytes. In fact, all of the combined storage space on every hard drive in the world would Read More
Adding exponents is one of the three basic rules when dealing with the combination of two bases and powers. The general rule for it is as followed: when you want to multiply the powers with the same base, simply add the two exponents together. In other words, if the bases are the same number, to multiply the two together, simply add the two exponents together to gain the right answer. Before that can be done, though, it is important to understand what a base and exponent are. What are Bases Read More
Just as you would add two numbers such as 2+3, you add two square roots in a similar fashion. The only difference between adding two square roots and adding two rational numbers (1,2,3…) is that you might not be able to simplify the answer down to a single number. Instead, you might be left with the most basic form, but still have a square root in there. When dealing with the addition of square roots, this is an entirely plausible and possible situation. How to Add Square Roots When you Read More
A zettabyte describes a unit of data or information that is equal to 1,000,000,000,000,000,000,000 bytes. The term is equal to a billion terabytes and the symbol ZB represents it. Zebibyte (ZiB) describes a measurement of data using the power of 1024. A single zettabyte is equivalent to 1,024 exabytes and is used prior to the yottabyte unit of measure. Due to the zettabyte’s large size, it is rarely used in industry to describe data storage or network throughput capacity. Examples of Zettabyte Use Over the past year, the total amount Read More
The term “big endian” describes the order in which a sequence of bytes is stored in computer memory. In the big endian storage sequence, the most significant value in the sequence, or the “Big” end, is stored at the lowest storage address (ie the first position). The alternative method of memory storage is referred to as little endian, where the least significant value in the sequence is stored first. For example, if the hexadecimal number 4E51 was stored in big endian format it would be saved as the value 4E51. Read More
