There are four main eras in the development of information technology.
- Pre Mechanical
- Electro Mechanical
The only era that has had a significant impact on humans so far is the electronic age, along with some elements of the electromechanical age.
3000 B.C. to 1450 A.D.
People initially made an effort to communicate through language or through crude graphic images known as Petroglyths, which were primarily carved in rock.
Later alphabets were developed, including the Phoenician alphabet.
Pens and paper started to emerge as the use of alphabets and writing down information increased.
Wet clay was initially used only for markings, but later, paper was made from the papyrus plant. The Chinese, who produced paper from rags, arguably produced the most widely used type of paper. People needed a mechanism to permanently store all the information they were now writing down.
Following that, the first books and libraries are created. Egyptian scrolls were popular ways to record and save information. Some people were actually binding paper into book-like structures.
The first numbering systems were also developed during this time period. People from India invented the first 1-9 system around 100 A.D.
Later, in 875 A.D., number 0 was invented, and once all numbers had been created, people wanted to do something with them, so calculators were invented. A calculator was the first sign of an information processor. At the time, the abacus was a popular model.
1450 to 1840.
As interest in this field grows, many new technologies are being developed.
The slide rule, a type of analogue computer used for multiplying and dividing numbers, was invented.
The Pascaline, a popular mechanical computer, was invented by Blaise Pascal.
Charles Babbage invented the difference engine, which tabulated polynomial equations using the method of finite differences.
The size of the machines invented during this time period was enormous in terms of the power behind them; it may appear absurd, but these inventions were enormous to the people who lived at the time.
1840 A.D. to 1940 A.D.
These are the early days of communication. In the early 1800s, the telegraph was invented. Samuel Morse invented Morse code in 1835. Alexander Graham Bell invented the telephone in 1876. Guglielmo Marconi invented the first radio in 1894. All of these were extremely important emerging technologies that led to significant advances in the field of information technology.
The Harvard University Mark 1 was the first large-scale automatic digital computer in the United States, built around 1940. This computer stood 8 feet tall, 50 feet long, and 2 feet wide, and weighed five tons. Punch cards were used to program it. It was from large machines like this that people began to consider downsizing all of the parts, first for use by businesses and finally for use in your own home.
1940- Until Now.
The ENIAC was the first high-speed, digital computer that could be reprogrammed to solve any computing problem. This computer was created for the US Army to use for artillery firing tables. This machine was even larger than the Mark 1, occupying 680 square feet and weighing 30 tonnes. It calculated primarily using vacuum tubes.
The four primary categories of computing are described here.
The first was the time of punch cards and vacuum tubes, such as the ENIAC and Mark 1.
Transistors and magnetic tape took the place of vacuum tubes and punch cards in the second generation, respectively.
High-level programming languages like FORTRAN and COBOL were also developed during this time.
Until the third generation of integrated circuits, every computer used magnetic tape.
Around this time, the real operating system and the sophisticated programming language BASIC appeared.
The fourth and most recent iteration included CPUs that combined logic, control, and memory circuits onto a single chip. The creation of the personal computer (Apple II). Additionally, the graphical user interface (GUI) was created.
Ecommerce Softwares and other Delivery softwares to which promotes social distancing were having huge demand.
Whether business or personal after completion of website its gives your benefits of having a website once you properly maintain the website.
You have a 100 percent responsibility to keep your company up to date if you are going to put a website in place. Hold it active if you have a blog. People will visit your website and what will your customers think if you don’t have updated address or phone number or any such content. Incorrect information can jeopardise your purpose’s credibility.
Emphasis on Experience
Every company strives to please their customers. As the owner, your primary responsibility is to ensure that your website informs prospective clients and serves as a tool for achieving your business objectives in creating the website. Then, concentrate on improving the user experience.
Backup & Security
A secure website ensures that your website and the customer data you collect are always secure. Stay on top of your website maintenance procedures and stick to a regular website maintenance programme to avoid any unnecessary website headaches.
Open source is a collection of rules and standards for writing software, the most critical of which is that the source code is accessible to all. In 1983, the free software movement began. In 1998, a group of people proposed that the word “free software” be replaced with “open source software” (OSS) as a less vague and more appropriate term for the business world. Software developers can wish to release their work under an open source licence so that others may build on it or learn how it works.
Open Source Software’s Advantages:
There is no need to purchase or upgrade costly server software licences. The service comes with all necessary software and has never needed additional software.
The main explanation for this is that it is virus-free. It also operates with hardware with a lower configuration. You won’t need to invest in more advanced hardware.
Almost every software release has flaws. When a flaw is discovered in proprietary software, only the original developers have access to the source code, because they are the only ones who can patch it.Open source software, on the other hand, is special. Errors appear to be more noticeable and fixed more quickly because a large number of users can access and modify the code. One of the slogans of the open source movement is that all vulnerabilities are shallow if there are enough eyes on them.
Closed source applications can only be customized or adapted by the original vendor. Open source applications may be customized by anyone with the requisite skill. Thus, open source software can be readily adapted to meet specific user needs. Even if you cannot program yourself, it is easy to post a feature request on an open source software project’s home page.If you need something added or customised right away, you can usually hire a qualified software developer to do it for you.
It is easy to translate the user interface language when you have access to the source code. Large closed source commercial software vendors are generally unable to translate their goods into lesser-spoken languages because the demand for them is too limited to make a profit.
Learning Is Simple
If you’re interested in learning to programme, open source code is a great place to start, and open source projects provide a realistic setting in which to put your skills to the test. Observing the creation process can be educational in and of itself. When you contribute code to an open source project, it is usually reviewed and commented on by professional programmers.You can be given full committer privileges once you have persuaded the project community that your code is of sufficient quality.
Large Community Support
When you use open source software, you join a group of users and developers who want to help one another and improve the software. It’s up to you how involved you want to be in this culture, but if you do, you can reap the intangible rewards of goodwill.
There are a number of leading software and development companies that provide a variety of powerful Open Source Software that offers low-risk, low-cost functionality. Rather than taking the costly and risky route of creating a custom site from the ground up, First Rate uses a proven base system and plugs in proven modules as needed.
