It’s hard to imagine existence without computers nowadays. We work or play with our phones and discover the things we want to know through computers. We often forget that our smartphone is a smaller model than our desktop computer.
The term “computer” could be applied to any device that is equipped with a microprocessor inside, most people view computers as devices that receive input from the user using the use of a keyboard or keyboard and then process it in a certain way and displays the outcome on the monitor. The software and hardware inside computers have advanced at a lightning-fast pace over the last few decades those heavy desk-crushing machines in the 1980s were very different from the lightweight touchscreen tablets of today.
1: The All-Powerful Personal Computer
An IBM Computer terminal that is used to conduct official scoring for the PGA tour was located in the press room at the 1994 Mercedes Championships in Carlsbad, California. Computers have advanced in the years since.
The term “personal computer” (PC) is a type of computer that is designed to be used by one person. Although an iMac can indeed be described as an example of a PC, the majority of people are referring to computers running on Microsoft’s Windows operating system instead. PCs first became known in the early days as microcomputers since they were full computers constructed on a smaller scale than the massive systems currently that are used by companies.
In 1981, the legendary tech company IBM introduced its first computer using Microsoft’s legendary operating system called MS-DOS (Microsoft Disk Operating System). Apple continued the trend in 1983 by launching the Lisa which was one of the first PCs to have an interface called a GUI (graphical user interface). This is a fancy way of saying that “icons” were visible on the screen. Before the advent of computers, screens were simple.

In the 1980s, users could only choose one PC (and that was the desktop model. The knee-knocking boxes (called “towers”) were large enough to slash your shins. They were equipped with huge CRT (Cathode Ray Tube) screens, these machines filled your workspace at home or in the office. The expectation for desktop systems was to install the computer in a central place. The majority of desktops provide greater performance, storage, and flexibility at a lower cost than their portable counterparts, which was the reason they were the preferred computer of the early 1990s when laptops were not yet a million dollars.
Nowadays, desktops are considerably less expensive than they were a decade ago in the past, and you can own one for as little as a few hundred dollars. This is a huge difference far from the many thousands they cost back in the 1980s. In actuality, Hewlett-Packard’s earliest business-oriented PCs, called the 300, cost $95,000 when it was launched in 1972.

In the past in the past, if you wanted to utilize a PC were required to have a desktop. Engineers couldn’t compress the advanced systems inside the PC into a portable box. In the late 1980s, however, there were a lot of big computer makers who launched a campaign to promote portable computers.
the laptop is a portable computer that includes the display keyboard, trackball or pointing device processor memory, and hard drive all within a form of a battery-operated device that is smaller than the average hardcover book.
The first commercial laptop was, however, not as sleek as the sleek devices that are found in retail stores today. Osborne 1, the Osborne 1, released in 1981, was priced at around $1800. It had 64 megabytes of RAMthe device weighed in at 24lbs (10 Kilograms). In addition to sculpting your biceps as well, this Osborne 1 also gave your eyes a workout, since the screen’s size was only five inches (12 centimeters).

A workstation is the name of a computer for desktops that comes with higher-powered processors with additional memory, top-of-the-line graphics adapters, and improved capabilities to perform a specific range of tasks like 3-D graphic graphics or games development.
Workstations, just like desktops are designed for individuals. They differ from desktops because they’re much, much more efficient. It’s usually businesses such as companies in the field of engineering or multimedia that purchase these PCs for their staff.

A computer is made to be optimized to connect to other computers on the internet, servers generally come with powerful processors, plenty of memory, as well as large hard drives.
In contrast to a laptop or desktop PC, you can’t just have to sit at a computer and write. Servers instead provide computing electricity — plenty of it, via local area networks (LAN) or the internet. Large and small businesses rely on servers to supply data, manage orders, keep track of shipping information as well as to crunch formulas for scientific research, and much more. Servers are typically located on racks within an area designated for servers and in some firms could look like warehouses.
As with computers, servers also have common computer components. They are equipped with motherboards, video cards, RAM as well as power supplies, and plenty of network connections to meet any requirement. They do not typically possess dedicated displays, however. Instead, IT professionals utilize a single monitor to manage and configure multiple servers and combine their computing power to achieve more speed.

At the beginning of computing, primary frames used to be enormous machines that could fill the entire space or an entire floor! The size of computers has decreased and their power has grown in the past, the term “mainframe” has been largely discarded to be replaced by corporate servers. It is still used, however, especially in large organizations to refer to the massive machines that process millions of transactions each day and simultaneously meet the demands of hundreds many, if not thousands of individuals. While the term “mainframe” was traditionally used to refer to central computers linked to smaller devices such as workstations, this distinction is changing as smaller computers get more power, and mainframes become more adaptable.
Mainframes were first introduced after the end of World War II period when their owners in the U.S. Department of Defense increased their energy in the fight against the Cold War. Although servers have become increasingly numerous Mainframes continue to be utilized to analyze some of the largest and most intricate databases in the world. They are used to protect a variety of sensitive transactions, ranging from mobile payments to highly classified corporate information.

The type of computer typically costs hundreds of thousands, to even millions of dollars. Although some supercomputers are just single computers, the majority consists of several high-performance computers operating in tandem as a system. The most famous supercomputers are created by Cray Supercomputers.
Supercomputers differ from mainframes. Both computers provide immense computing power to perform the most demanding scientific and industrial calculations. Mainframes are typically modified to offer the highest level of data security.
Supercomputers, in contrast, can be described as they are Formula 1 race cars of the computer world. They’re designed for speedy processing, which allows companies to speed through calculations that would require other systems to take days, weeks perhaps even months to finish. They are often found in locations like atomic research centers as well as spy agencies, research institutes, and weather forecasting stations where speed is of primary importance. For instance, The United States National Oceanic and Atmospheric Administration which has one of the most advanced capabilities in weather forecasting employs some of the most powerful computers that can handle greater than eight quadrillion computations every second.
