Generations of Computers

Computers are an essential component of our daily lives especially now when most individuals don’t see their need yet with the contributions made added to living. Additionally, the generations that has progressed from conception to the worldwide laptop and desktop computer development as from the 1980s. Nevertheless, the computer’s history extends back a few generations and has several computer generations.

 

 

1940 – 1956: First Generation – Vacuum Tubes
The pioneering machines had vacuum tubes for storage being magnetic drums and circuitries. Consequently, they were huge, occupying most the spaces practically and needing a high cost and labor to operate. They were ineffective items that used high amounts of heat, drew enormous electricity, and then produced a lot of heat that caused continuous breakdowns. thats why when something breaks give Vann Heating & Air a call.

 

1956 – 1963: Second Generation – Transistors
Transistor substitution in place of vacuum tubes led to the emergence of the second-generation computers. Even though created for the very first time in 1946, they were not used in pcs considerably until the early 1960s. They were a major upgrade compared to the earlier tubes, given the fact that the machines were still susceptible to harmful thermal quantities. They were, nevertheless, highly inherently better to the first tube, because the machines were slimmer, quicker, easier, and far less dependent on energy use. They still depended on printout boards.

 

1964 – 1971: Third Generation – Integrated Circuits
By this stage, the transistors had now started being phased out and being replaced with silicon chips. This resulted in a huge rise in these computers ‘ precision and effectiveness. They were the pioneer machines where people would input using buttons and screens that networked with an OS, an important change from the printouts. This allowed the computers to operate multiple apps simultaneously using a core program that worked with monitor memory.

 

 

1972 – 2010: Fourth Generation – Microprocessors
The transformation can be described using one phrase: Intel. In 1971, chipmakers created Intel 4004 processor, which fitted all software parts (CPU, storage, output, input devices) on a single cartridge. What crowded a place in the 1950s now fits in a person’s hands. This type of chip contained hundreds of integrated circuits. The year 1980 had the creation of the first desktop computer (IBM) primarily intended for room use while the MacIntosh was launched by Apple in 1984. The microprocessors shifted above the domain of pcs and into a growing amount of daily products.

 

2010- : Fifth Generation – Artificial Intelligence
Computer with AI are still in progress stage, and even some of the innovations are starting to surface and even are being used for speech recognition. Their importance is that they will lead to the creation of devices that understands natural language.

 

Technologies that will further improve internet speed

We are living in a computer world and when we talk about computer, we cannot disregard the importance of the internet. It is surprising to know that more than half percent of the total population in the world don’t have internet access. Fortunately, there are research and development projects that aim to improve internet access and speed. The goal is to get the world online all at once. Let us take a look at the technologies that will make the internet speed super fast.

 

 

· Solar-powered internet-beaming drone – Mark Zuckerberg, the founder of Facebook is in a mission to connect the entire globe to the internet. He aims to launch a big soaring drone to beam out the world’s access to the internet. Facebook has its own connectivity lab and it made a solar-powered drone. It has a massive wingspan. In June 2016, the first test flight was done and it was a success. The research still continues to work on it by equipping it with the most advanced innovation. The goal is to come up with a highly energy-efficient drone that simultaneously beams out internet access to areas that need internet.

 

· Wireless internet access based on LEDs – A French start-up has come up with a wireless internet technology using LED. It is said to be a hundred times faster than the current WiFi. This technology is called Li-Fi. It uses the flicker rate of the LED lamp; a frequency higher than the radio waves of the existing wireless internet. It is called Li-Fi because it is dependent on light. Without light, it won’t work. The strength of this technology is its secure nature making it perfect in places where privacy is a must.

 

· Internet access in deep space – Is it possible? Well, anything is possible with NASA. Scott Kelly, an American astronaut became an internet star when he posted a jaw-dropping view of the earth from his outpost in the stars. NASA was able to deploy a new technology to the ISS that could be used to relay internet service into deep space.

 

· MIT’s faster WiFi – The researchers at MIT Computer Science and Artificial Intelligence Lab came up with a new wireless internet that is way faster than the existing internet speed. Its bandwidth is twice the existing technology. It uses multiple transmitters and receivers so as to simultaneously relay the data and increase the number of data in a particular bandwidth. It addresses spectrum crunch by distributing data differently so as to prevent congestion on the network.

 

How Your Computer Can Help You Study

 

It is that time of the year again, isn’t it? If you are a first year university student, you probably have to deal with post-secondary institutions, and it is probably not too easy for you right now. You don’t know what you are doing, where you are going, or even how you are going to get there. It is safe to say that one of the most difficult aspects of a student life – aside from organizing your time and balancing a healthy social lifestyle while trying to get as much work as possible – is studying.

A lot of students find it pretty difficult to constantly concentrate and focus on all the things that they have to do in order to pass all those exams that don’t seem to ever let them enjoy a good night sleep. If you belong to this group of students, then you probably think that your computer would be the most daunting adversary to effective studying, don’t you? Well, if you think this way, you should change your way of thinking right now! But really, when you take some time to think about it, it is pretty much safe to say that the Internet is one of the worst things that you can spend your time on. However, using the Internet has its advantages too. In fact, your computer can be a lot more helpful than you may have thought. You just have to know how to use it for the right things!

Your Computer Can Help You Get Organized

Organization plays a very important role when it comes to inhabiting effective study habits. Due to the fact that you are a student, you need to manage your time somehow, and if you are not really sure as to how to do that, your computer could be your best friend. After all, keeping all of your books and notebooks organized is never as easy as keeping your computer’s files and folders organized!

Music Can Help You

You are probably not going to believe this, but listening to good music can actually help you focus. Although your MP3 player probably does a pretty good job with this, there is one thing that it can’t provide you with, and the thing that we are talking about here is called YouTube. However, don’t allow yourself to get distracted! Log on, find something that fits your taste, and immediately get back to work.

Social Networking

If you need a help from your friend, there is no easier way to reach them than to use social networking. Social networks can be much more useful than some people think. You just have to use them the right way, and everything is going to be okay.
