Answer the following questions
The CPU is the computer hardware component that’s responsible for interpreting and executing most of the commands from the computer’s other hardware and software. It is used to manipulate data-is responsible for carrying out
arithmetic and logic functions. It is seen as the brain of the
computer. Some devices that use a CPU include desktop, laptop, and tablet computers and smartphones. CPU’s come in a variety of speeds which are known as ‘clock rates’. Clock rates are measured in ‘Hertz’.
Generally, the faster the clock rate, the faster the performance of the computer. Intel and AMD are the two most popular CPU manufacturers for desktops, laptops, and servers, while Apple, NVIDIA and Qualcomm are big smartphone and tablet CPU makers. Components of a CPUThe TWO MAIN components of a CPU include the following:
The computer can only do one thing at a time. Each action must be broken down into the most basic steps. One round of steps from getting an instruction back to getting the next instruction is called the Machine Cycle. Four steps of Machine cycle
*************************************************** Memory is made up of bistable devices. Bistable means the components that make up memory can be set to one of two states either on or off. These two states are represented using binary digits- 0 for off and 1 for on. As such, the smallest unit of storage of memory is called a binary digit (bit). The amount of data and instructions that can be stored in primary storage or secondary storage media is measured in bytes. Byte – A byte is made up of a combination of 8 bits and has the capacity to represent one character i.e. a letter, a number, a symbol, a punctuation mark or a blank space. Nibble – A nibble is made up of a combination of 4 bits. Word – A word is the amount of bits the computer can process in one operation. Word size – A word size or word length is the number of bits in a word. For example 32 bits and 64 bits Home work

Source: Economist 2010. We wish to quantify information or data for the purpose of storage or transfer. This helps us plan the capacity of storage systems or the bandwidth of communication systems. Service providers also use these numbers to determine pricing. The basic unit of information is called bit. It's a short form for binary digit. It takes only two values, 0 or 1. All other units of information are derived from the bit. For example, 8 bits is called a byte, which is commonly used. Since the early 2010s, we're seeing a massive growth in the amount of data being generated worldwide. This has led to the use of higher units such as petabytes and exabytes. In the world of quantum computing, qubit is the basic unit of information. Discussion
MilestonesHartley studies the problem of measure information. Given \(s\) symbols and \(n\) selections, he notes that information \(H=n\,log\,s\). He describes this as, our practical measure of information the logarithm of the number of possible symbol sequences Claude Shannon publishes his paper titled A Mathematical Theory of Communication. He introduces the word bit as a contraction of binary digit. He credits J. W. Tukey for coining this word.
During the design of IBM 7030 Stretch, IBM's first transistorized supercomputer, Werner Buchholz coins the term byte for an ordered collection of bits. It represents the smallest amount of data that a computer can process. At this time, the byte is not defined as eight bits. During this decade, 7-bit ASCII is standardized. More importantly, IBM introduces its System/360 product line that uses 8-bit Extended Binary Coded Decimal Interchange Code (EBCDIC). This leads to the popular use of 8-bit storage systems. Thus, a byte comes to represent 8 bits. The prefixes exa and peta are standardized as part of the International System of Units (SI). The prefixes zetta and yotta are standardized as part of the International System of Units (SI). Windows 10 uses GB when it should use GiB. Source: Devopedia 2019. The International Electrotechnical Commission (IEC) publishes new units of information based on powers of two: kibibyte, mebibyte, gibibyte, and so on. The letters "bi" replace the last two letters of the SI prefixes. While some systems have adopted these units, many others have not. References

A byte is the unit most computers use to represent a character such as a letter, number or typographic symbol.
When describing a computer storage or memory we use a unit known as the?Computer memory uses a portion of the International System of Units (SI) prefixes for multiples of the base unit, a byte. The prefixes are not truly metric, however, because a byte is eight bits, a kilobyte is 1024 bytes.
What is eight bits of data called?A byte consists of 8 adjacent binary digits (bits), each of which consists of a 0 or 1. (Originally, a byte was any string of more than one bit that made up a simple piece of information like a single character. Thus, for example, there were four- or six-bit bytes, but eventually the standard settled on eight bits.)
What is meant by bits and bytes?Bits and bytes
So computers work by manipulating 1s and 0s. These are binary digits, or bits for short. Single bits are too small to be much use, so they are grouped together into units of 8 bits. Each 8-bit unit is called a byte. A byte is the basic unit which is passed around the computer, often in groups.
