Intel has come into the microprocessor domain in 1971. In 1971 they have released the processor 4004 which is a 4 bit processor. They have come up with a 4 bit microprocessor in 1971 in the month of November just after 6 month they have come up with the enhanced version of the processor and the next processor is known as your 8008 which is an 8 bit processor. So in the timeline of 6 month they have enhanced the 4 bit processor to 8 bit processor.
Detailed Explanation
In 1971, Intel launched its journey into microprocessors with the 4004, which was a 4-bit processor. This was a significant step because it laid the foundation for modern computing. Just six months later, in May 1972, they introduced the 8008, an 8-bit processor that represented an enhancement over the 4004, allowing for greater data processing capabilities. This progression shows how quickly technology was advancing even in the early days, highlighting the rapid evolution from simple processing capabilities to more complex ones.
Examples & Analogies
Think of the 4004 like a basic smartphone that can only make calls and send texts. The introduction of the 8008 is akin to that smartphone gaining the ability to browse the internet and run apps, drastically improving its usability and functionality.

Next they have come up with 8080 in April 74 after 2 years and now which became a standard for an Intel group and many people are using these things. They have standardized the processor now in 1976 they come up with microprocessor 8085 which works on 3 Megahertz.
Detailed Explanation
After the 8008, Intel continued improving their processors. In April 1974, they released the 8080, which was a 16-bit microprocessor. It became a standard in the computing industry due to its enhanced performance. By 1976, they introduced the 8085, which operated at a clock speed of 3 MHz. This increase in speed and bit capacity allowed for more complex calculations and processing tasks, showcasing Intel's commitment to pushing the limits of processor technology.
Examples & Analogies
Imagine upgrading from a basic calculator to a scientific calculator; the scientific calculator can not only perform addition and subtraction but also handle complex equations, just like how the transition from the 8080 to the 8085 allowed for improved computational capabilities.

In the same year they have slightly modified it and come up with your 8086 and which is a processor which is used to build computers, along with that they are coming up with another processor called 8088. These are processors 8086 and 8088 which are used to build computers in that either this maybe in eighties.
Detailed Explanation
In the evolution of Intel processors, the introduction of the 8086 and 8088 marked a major step toward personal computing. Released in 1976, these processors formed the foundation of the x86 architecture, which is still in use today. The 8086 was significant because it supported 16-bit computing, allowing for more efficient processing and memory management, crucial for developing early personal computers.
Examples & Analogies
Consider the 8086 and 8088 processors as the first models of cars designed for mass production. Just as those early cars made driving accessible to the average person, these processors made personal computing possible, paving the way for the computers we use today.

So this is your 86, now you just see that in 76 that processor works at 3 megahertz, but now in after 10 years this processor is working 10 megahertz. So I think you know this particular frequency; that means, this is the clock frequency. So if I talk about this particular clock frequency I can say that it is having some duration whatever duration I am having d then frequency is nothing but one upon d.
Detailed Explanation
The progression from a clock speed of 3 MHz in the 8085 to 10 MHz in the 80186 demonstrates the dramatic improvement in processing speed over just a decade. Clock frequency, the rate at which a processor can execute instructions, directly correlates with performance. As the frequency increased, so did the processor's ability to perform tasks more quickly and efficiently, which is crucial as software demands also escalated.
Examples & Analogies
Imagine a teacher (the processor) able to grade papers (execute instructions). At a slow pace, they can only grade a few papers an hour (3 MHz). With training and resources, they become faster and grade multiple papers in the same time period (10 MHz), allowing them to handle larger classes and respond to students' needs more efficiently, paralleling the improvement in processor speeds.

After that computer Intel is developing their processor and making more and more advanced and they are about to release 80586, but some issues arises over here and due to that they have changed the nomenclature now from instead of numbers they are coming to name. So instead of releasing 586 Intel has released that Pentium series.
Detailed Explanation
As technology advanced, Intel faced challenges with naming conventions for their processors. Instead of simply continuing with numerical designations like 80586, they opted for a brand name, 'Pentium', which was introduced in 1993. This change not only marked a new generation of processors but also helped in marketing the technology, making it more recognizable to consumers and signifying a leap in capabilities.
Examples & Analogies
You might think of 'Pentium' like a new model name for a smartphone that signifies a major update in features. Just as consumers are drawn to new smartphone models with improved features, the Pentium name helped distinguish these advanced processors in a crowded market and emphasized their superior performance.

At that particular point users see that the operating frequency is now going from megahertz to gigahertz trends. So 1.3 gigahertz means you know 1.3× 10^9 hertz and when you talk about a megahertz it is 60 into 10^6 hertz.
Detailed Explanation
The shift from megahertz (MHz) to gigahertz (GHz) represents a monumental leap in processor speed. For instance, a 1.3 GHz processor can execute 1.3 billion cycles per second, a significant increase compared to older MHz processors. This change enabled computers to perform even more complex tasks in real-time, revolutionizing the computing experience.
Examples & Analogies
Think of this transition like moving from reading a book slowly at a leisurely pace (megahertz) to speeding through it quickly enough to summarize it in mere minutes (gigahertz). This speed allows for quick access to information and seamless multitasking on computers today.

After that till the Pentium M we have only one processor and all the job will be carried out by this particular processor then they have come up with the multi processor. So inside a particular microprocessor chip we may have 2 processors. So Core 2 duo, so in that particular case we are having two processor they are integrating together so; that means, we can perform some parallel task.
Detailed Explanation
Intel's innovation didn't stop with faster single-core processors; they also moved to multicore processors like the Core 2 Duo. These processors contain two or more cores on a single chip, allowing them to perform multiple tasks simultaneously. This parallel processing capability significantly enhances computing efficiency and speed, catering to the growing demands for multitasking and complex operations.
Examples & Analogies
Imagine a busy kitchen where instead of one chef trying to prepare all the dishes, you have multiple chefs (cores) each working on different dishes at the same time. This helps serve meals faster and manage many orders efficiently, just like how multicore processors handle multiple computing tasks more effectively.
