The Timeline of Computers

            Bill Gates, the co-founder of Microsoft Corporation, declared that “the computer was born to solve problems that did not exist before.” Technology is rapidly altering before our very eyes and keeps bringing new expectations and perceptions of life.   Within six decades, computer technology has stemmed from demanding an entire room to function to a table, to pockets, and now operating mainly from a Cloud.  The original intention for computers was merely for a mathematical calculator.  Currently, calculators are in all of our electronic devices. Therefore, computers have and will keep changing the future for generations to come.

Original Computers

            During the 1940s and 1950s, the first large-scale computer called Electronic Numerical Integrator and Computer (ENIAC) ran at electronic speed without delay by any mechanical parts. The ENIAC needed 18,000 vacuum tubes to function. Also, it required 15-by-meters of space for its sizable built.  This technology was cutting edge. The accessibility of this technology became possible later on. 

            Nevertheless, transistors brought smaller and dependable computers altering from the more expensive computers. Cheaper and tinier, computers started to become a high demand in the market. The IBM 608 was the first transistor-only computer costing around $1,760 a month to rent compared to the IBM 650 being $3,200. The 1950s and ’60s embarked on the current computer industry. The IBM 608 was considered the first commercial calculator. IBM produced 70% of the world’s computers, and 80% were within the United States.

            In 1971, Intel generated the first commercial microprocessor called the Intel 4004. They brought in the next generation of computers called the IBM PC. The cost of computers lowered, and microprocessors were the next step for computers. They empower mass production of custom-made CPU systems. IBM’s larger transistors were no match for microprocessors which brought about miniature computers, PCs, laptops, and even the mobile phone. Eventually, in 1974, Motorola would be a competitor to Intel by making the 6800 microprocessor computer.

Personal Computers

             Within the hardware level of computers, microprocessors were bringing about a menacing completion.  During the 1980s and 1990s, computers’ previous constructions were manipulated to serve customers. Hardware companies like Intel, Zilog, Motorola, and MOS Tech had to contest with each other. An operating system (OS) running by consecutive software increased the demand for mass production of computers. Microsoft eventually saw the need to bring all applications into one operating system.  By the late 90s, Microsoft’s operating system resulted in 97% of all computing devices. Therefore, Microsoft’s operating system and Intel’s microprocessor shaped a new era for computers and led to fierce competition.

Internet and Now

The Web (HTTP) and the introduction of Linux, an open-source operating system, led to the most notable shift of technology in history. Internet browsers escorted users to cross-OS access to terminating the application lock-in benefit of Windows. Also, Microsoft lost the opportunity to shift towards mobile consumption paying particular more attention to software developments. The Linux-based mobile operating system, Android, outshined  Microsoft. Android took the computing market by controlling 85% of the mobile computing market. Mircosoft’s stock went down 20% afterward.

Notably, another creation made for computer users to experience a convenient and connective way of using computers in the Cloud. It allowed users to save data and have storage online. Cloud is now the main focus with tech giants such as Google, Apple, Amazon, and Microsoft.

Therefore, many of these tech organizations are still striving to create an experience with computers. Technology will keep changing and transitioning our lives.

Laptops Computers vs Desktop Computers

While the age of paper thin and hyper speed computers are upon us, many still question whether a desktop or laptop computer would best suit them. Both types of computers have their benefits and their downfalls, but they all grant the gift of infinite possibilities and resources.

Performance

It’s entirely possible to find incredibly high performance computers that can accomplish everything you need in both laptop and desktop form. Though for the sake of comparison, a laptop equipped with comparable features and components to those of a desktop computer will not perform as well. This is due to the fact that laptop parts are made smaller and lighter for mobility purposes, sacrificing some speed and performance.

Price

Price is arguably the biggest factor most people consider before purchasing a new computer and those who haven’t shopped around recently may be surprised to see just how far their money can go. Even though desktop computers tend to have better rates of performance than laptops do, they often cost much less. A laptop computer with similar parts as a desktop computer can cost as much as fifty percent more.

Portability

Though this may seem obvious, desktop computers are not ideal for those who are frequently mobile. Desktop computers have a reputation for being bulky and heavy, and even though that is becoming less true every year, there is some truth to it. Those who need to be near a computer at all times would most benefit from the freedom a laptop offers, though there is always the option of investing in both!

Conclusion

While desktop computers are typically better performing and lower in cost, it can be hard to not see the appeal in a computer that’s both ultra-thin and lightweight. Computers are wonderful tools when they work properly but can be incredibly frustrating and confusing when they don’t.

Hardware Compatibility

When you’re building a gaming PC, your number one priority should always be the compatibility of the parts. Everything from the processor and CPU to the motherboard should be compatible before you make that purchase and install them.

Memory Speed

No matter what type of memory you purchase for your rig, you should always check to ensure you’ll actually be using all of that memory speed. You can check this by entering the BIOS (Basic Input/Output System)** and loading the memory profile. There are also plenty of third-party apps which will show you your computer’s current memory speed.

** BIOS: firmware used to perform hardware initialization during the booting process, and to provide runtime services for operating systems and programs.

An 80 PLUS Rating for the Power Supply

Your computer’s power supply should be able to stand up to the games and other tasks you’re planning on using your PC for. By choosing a power supply which has an 80 PLUS certification will guarantee your gaming PC can handle just about anything you plan to throw at it.

Cable Management

Once you have all the computer components and you’re ready to put it into the case, you want to make sure everything will fit and look clean. Cable management is key in achieving a nice, clean appearance for your rig. Fun fact: good cable management might also help improve the cooling system due to the improved air flow inside the case.

Overclocking: Worth it?

Overclocking and whether it’s worth it or not is completely subjective. Overclocking is the process of speeding up your computer beyond the manufacturers’ specifications for a faster runtime. If you feel it’s worth the possibility of burning out your rig’s components and voiding the parts’ warranties, then your performance goals can be met through overclocking. Just be sure to weigh the pros and cons before making the final decision.

Conclusions If you’re ready to get started playing all of your favorite PC games on a system you’ve built yourself, following these tips for ensuring your PC survives will help a great deal.

Ways to Keep Your Computer Running Faster

A computer is an incredible and revolutionary piece of hardware that can do seemingly everything you need it to do. However, if not taken care of properly, the device that you consider one of the most important parts of your daily life can become a consistent source of stress. There are a multitude of reasons why a computer starts to slow down when it comes to performance, but what a lot of people don’t realize is that there are plenty of ways to keep this from happening. In the article below, you will be given a few simple steps that can do wonders for keeping your computer in tip-top working condition.

Don’t Let Any Programs Run Automatically:

Something that is often overlooked by most people are the programs that are set to open by default when turning the computer on. Not only is this usually unnecessary except for antivirus programs, but it also greatly effects the overall functionality of your computer. While it may not look like it to you, the programs running in the background take up a lot of your computers RAM, which basically means that they are taking away some of the attention your system has to give, directly effecting how much it can provide to whatever you are actually using the computer for. The fewer programs running the better when it comes to any hardware, which means unclicking that pesky little “start automatically” box can make a whole world of difference.

Uninstall Any Unused Programs:

How many people know every single bit of software and every program on their computer? Besides professionals that work with computers for a living, it is most likely that you don’t know every program or file that is taking up memory and space on your hard drive, which is understandable. With such an intricate system, there are bound to be certain programs that are completely irrelevant to you while possibly being extremely important to other people. The important thing to do in this situation is take the time to search through your computers downloads and applications to see exactly what is in there and how much space it takes up. If you know you aren’t going to use it much or at all and it serves no true daily purpose to be on your computer, uninstall it. The more space you can free on your computer, the faster it will run.

Save All Videos & Photos on External Hard Drive:

Speaking of freeing space on a computer also brings audio, video and picture files to mind. When it comes to these kinds of files, it is extremely easy to lose track of just how many of them you’re saving on your computer. In today’s digital age there is no shortage of opportunities to take a selfie or capture that amazing view, which then gets saved onto your hard drive to take up even more space. While there is nothing wrong at all with saving cherished memories, there is also no reason to keep them on your computer. Purchasing a simple external hard drive of 1 or 2 terabytes will allow you to store every bit of media footage, whether it’s photo or video on that drive and delete it from your actual computer, thus saving a huge amount of space for you to devote towards performance and speed.

Run Consistent Disk Cleanups:

With so many different websites we visit and temporary files we need for either school or work, a virtual junk drawer of unneeded files, programs and cookies can steadily start to pile up in your computer. While at first it may seem harmless, given enough time these random little bits of space can add up to a very slow operating system. Luckily, there is a very easy way to counteract this frustration, which is to run monthly or even weekly diagnostic checks and disk cleanups. By running these checks or merely just going into your computer to delete any recent unnecessary files or cookies, you save vital disk space and allow your computer to operate at its finest.

Conclusion:

Plenty of issues can arise with such a complicated piece of technology, but your computer is actually a relatively simple device to keep up if you know how. Following these few simple tasks can do wonders with creating better functionality and less frustrations for you. If there is an issue that can’t be fixed simply by yourself, however, National Computer Repair is happy to help you get back up and running in no time!

The Main Components of a Gaming PC

If you’re heavily into playing PC games, it’s worthwhile to invest in a gaming computer. While most PCs can play video games, specialized gaming computers totally enhance the gaming experience. These computers are built with components that are specifically designed to run video games efficiently without causing the computer to crash. What are these parts exactly? Read this blog post for a rundown of the main components required for a gaming computer.

Graphics Processing Unit

Graphics Processing Unit, GPU, Graphics Card, Video Card

The graphics processing unit is known as the GPU, graphics card, or video card. This component is the most important part for PC gaming; it’s what makes games look photorealistic without crashing your computer or slowing down the gameplay.

The graphics card relies on the processor (CPU) to function. If the CPU isn’t processing the game quickly enough, the GPU’s visual output will be bottlenecked, meaning that the FPS (frames-per-second) will drop and the game will lag or freeze. A high quality GPU working in conjunction with an efficient processor will give you a smooth gaming experience.

Check out our selection of graphics cards.

Processor

Computer Processor, CPU

The central processing unit, or CPU, is the brain of the computer. The CPU controls the number of tasks your computer can perform simultaneously, and how quickly it can do so. For gaming, the processor is the second most important component in a computer, as it works hand-in-hand with the graphics card.

Since the CPU is so important, make sure you are buying an up-to-date CPU and compare it with competitor brands to ensure that you are picking the best model possible. Many gamers purchase Intel processors, as their stronger single-core performance makes them especially suited for gaming; although, AMD processors are quickly becoming just as good as Intel processors in terms of gaming, and are more affordable.

Memory

RAM, Memory, Memory Card, Random Access Memory

Random Access Memory, or RAM, is the third most important component for gaming; it allows computers to quickly access files and run multiple processes simultaneously without lagging. It’s directly linked to the CPU, and greatly impacts the CPU’s performance and your gaming experience.

Speed isn’t as important as quantity; the more RAM you have, the better your system will be at managing multiple applications at once and meeting the memory requirements of today’s PC games. You will need at least 4GB of RAM for your computer (any less and your computer won’t be able to run most games), though 8 to 16GB are your best options.

Storage

Computer Storage, Hard Drive, Solid State Drive

To figure out how many gigabytes of storage you’ll need, look at how much space your current list of games require, and use that number to gauge how much storage to get. Then, you will need to choose between a hard drive (HDD) or solid-state drive (SSD). Having both is recommended, but we suggest getting an SSD if you can afford only one.

If you’re looking for quality, get an SSD – they are smaller, durable, provide faster loading times, and can store a significant amount of data. If you’re looking for quantity, opt for an HDD – they are larger, more affordable, and can store much more game data (though they can result in slower loading times).

Power Supply and Motherboard

Computer Motherboard

Computers need electricity to run, so a good power supply unit, or PSU, is critical. Don’t get a cheap, poor-quality PSU, or else the rest of your computer won’t perform well. Buy from a reputable manufacturer, and make sure that the unit you buy has enough wattage for your system. This Power Supply Calculator helps you determine how big your PSU needs to be.

Every computer part is connected in some way to the motherboard, so that every component can communicate and work together. Motherboards do not have any effect on gaming performance, so it does not matter what type you purchase, as long as it’s compatible.

Check out our selection of motherboards.

Case

Computer Case, Computer Tower

The computer case holds everything together and can make your system last many years without needing many rebuilds. Your case should have space for your motherboard, GPU, and for replacement parts that may be installed in the future. It should also accommodate for a cooling setup, allowing room for two fans and vents for those fans.

Check out our selection of computer cases.

Other Components

Operating System (OS): Windows 10 is the top recommended system for gaming, but if you can’t afford it, go for Linux operating systems.

Mouse and Keyboard: Consider the types of video games you like to play. Shooter games require a usable mouse, while MMOs, MOBAs, and strategy games need a quality keyboard.

Monitor: What’s the point of playing a video game if you can’t see anything? Invest in a good monitor that is compatible with your setup.

Fans: These keep your computer cool and prevent it from overheating. A high quality fan improves air flow, keeps hardware at a decent temperature, and reduces the noise coming from the computer.
