What is a Speed Memory on a Computer?

Increase Computer Speed Memory by Increasing the Ram (Memory)

Did you know that if you increase the memory on your computer, you can increase the speed? When you try to open a program on your computer, it needs to load itself from the hard drive into the memory. If the memory resources are low because there are too many programs open at the same time, or you have too many programs on your computer, this all takes memory to make things happen. The result will be a computer that runs very slow.

Nobody likes working with a computer that is slow. To have a computer that performs with speed, making the action process happen in 2-5 seconds, it is important to have ample RAM (memory) installed on your computer for computer speed memory. Many of the older computers might have 1 Gigabyte of memory if they are lucky, usually less. This is way too low by today’s standards. You should have a minimum of 5-6 Gigabytes of RAM and preferably 8-10 Gigabytes if you can afford it.

Each action performed, every program installed, takes up and uses computer memory. Don’t overload your computer. You can combat that by increasing the memory (RAM). Freeware contributes to a slow computer because it quite often comes bundled with other freeware that is installed on your computer. Many of those programs are just using up memory and are never used.

Tips for Computer Speed Memory Performance

There are several tips you should be aware of for computer speed memory to keep your computer running at maximum speed. Having the proper security programs on your computer is a must. If you try to shortchange yourself and your computer by not installing these mandatory programs just to save some money, you will ultimately pay the price down the road.

Security programs guard your computer against viruses such as worms, Trojan horses, adware, spyware, malware and other damaging viruses (just to name a few), to your PC. Use the best antivirus software, and keep it updated by version and daily updates. There is a constant new supply of viruses that attack your computer on a daily basis. Keeping all your programs updated, especially your security programs, should keep your computer protected.

When checking for the best antivirus programs, be sure and check all the problem areas listed on the landing page of the product, what the product protects, customer testimonials, product reviews, customer service, and a 30 day trial period with a full money back guarantee.

Ways to Speedup Computer Speed Memory

Run disk defragmentation.

Run disk cleanup.

Go to start all programs, click on accessories, system tools, and select disk defragmentation, and then run disk cleanup.

Uninstall programs that are no longer being used.

Click on start, control panel, uninstall programs, select and highlight program you want uninstalled, click on uninstall, when program is completely uninstalled, close out of the control panel and restart your computer to complete the uninstall.

Summary for Computer Speed Memory

Make sure you have plenty of RAM (Memory), preferable a minimum of 5-6 Gigabytes. If you can afford 8-10 Gigabytes this would be even better.

Using a good registry cleaner is the key to good performance

Use only the best antivirus software

To keep your computer safe, use good adware and spyware software programs

Also use a good Malware Program

Normally there is no – one program – that will deliver all the goods to keep your computer safe.

Keep your computer programs, driver devices, and all software updated at all times and make sure your computer is set for automatic updates from Windows Update.

Uninstall all the programs you no longer need or use on your computer.

Cloud Computing – Can It Be Safe?

On-premises computing is the traditional form of computing in which you or your company own and manage your own systems. All the applications you use, as well as your data files, are in your own computers on your own premises either on individual PCs or on an in-house local area network.

In cloud computing, by contrast, your applications and files are held remotely on the Internet (in cyberspace) in a network of servers which is operated by a third party. You access applications and work on your files from your PC simply by logging on to the network.

Cloud services are provided by cloud-hosting providers, companies such as Google, Amazon, Oracle Cloud, Rackspace, Microsoft Azure, and so on.

There is nothing fundamentally new about the concept of cloud services. If you are using Gmail, Hotmail or yahoo for your emails, you are using cloud services and probably have been for years.

What is relatively new is the types of services that are being offered in a cloud-environment. These now go far beyond email to cover all the IT services that an on-premises computing environment would deliver, such as accounting, marketing, human resources and so on.

Advantages of cloud computing

Cloud computing has several advantages over on-premises computing:

1) You can run an application or access your files from anywhere in the world using any computer.

2) Cloud computing is cheaper.

3) You need less technical knowledge.

4) Cloud computing delivers a better performance.

5) Cloud computing is eminently scalable. Increasing the number of applications you use or the amount of data you store does not require a heavy investment; you only need to advise the cloud-hosting adviser.

Given these advantages it no surprise that over the last few years there has been a widespread rapid adoption of cloud computing. Analysts estimate that the growth rate of all spending on cloud IT will soon be at least four times faster than the growth rate of all spending on on-premises computing.

Indeed, analysts are expecting the annual growth rate of spending on cloud computing to average 23.5% compound from now until 2017. In addition, by that year spending on cloud services will probably account for one-sixth of all spending on IT products, such as applications, system infrastructure software, and basic storage.

Given the rapid growth in cloud computing, the big question, of course, is whether cloud computing is safe. Is it more or less safe than on-premises computing?

The short answer is that cloud computing is not less safe than on-premises computing. However, the threats are somewhat different in nature, though they are converging.


Generally speaking, there are six major threats to computer security. These are:

Malware – is malicious software such as viruses, trojans, worms, spyware and zombies. Malware is installed on either a PC in your home-office or a cloud-computing server. Where malware gives control of a network of computers to a malicious group (eg, to send spam) it is called a botnet.

Web app attack – is an attack in which web-based applications are targeted. It is one of the most common forms of attack on the Internet.

Brute force attack – works by trying all possible combinations of letters or numbers in order to discover a cipher or secret key. For example, you could crack a password by repeatedly trying to guess it. Modern computing power and speed makes brute force a viable form of attack.

Recon – is reconnaissance activity that is used to choose victims that are both vulnerable and valuable.

Vulnerability scan – is an exploit using a special program to access weaknesses in computers, systems, networks or applications in order to generate information for planning an attack.

App attack – is an attack against an application or service that is not running on the web, ie the program will be on a computer somewhere.


A honeypot is a decoy website, network, system or application that has been intentionally designed to be vulnerable to attack. Its purpose is to gather information about attackers and how they work.

Honeypots allow researchers to:

  • collect data on new and emerging malware and determine trends in threats
  • identify the sources of attacks including details of their IP addresses
  • determine how attacks takes place and how best to counteract them
  • determine attack signatures (pieces of code that are unique to particular pieces of malware) so that anti-virus software can recognise them
  • develop defences against particular threats

Honeypots have proved to be invaluable in erecting defences against hackers.

The Spring 2014 Cloud Security Report

Alert Logic provides security services for both on-premises and cloud computer systems. The company began issuing cloud security reports in 2012. Its Spring 2014 Cloud Security Report covers the year ending 30th September 2013.

This report is based on a combination of real-world security incidents experienced by Alert Logic’s customers and data gathered from a series of honeypots the company set up around the world.

The report throws some interesting light of the security of on-premises and cloud computing relating to the company’s customers. Here are some of the highlights:

[1] Computing is shifting more and more from on-premises to cloud-based computing and the kinds of attacks that target on-premises systems are now targeting cloud environments. This is probably due to the increasing value of potential victims in the cloud.

[2] Although attacks on cloud environments are increasing in frequency, the cloud is not inherently less secure than traditional on-premises computing.

[3] The frequency of attacks in both on-premises and cloud computing has increased for most types of threats, though for a few types of threats it has fallen. Here are the main points of comparison between both computing environments:

The most prevalent types of attacks against on-premises customers were malware attacks (including botnets) at 56% during the six months ending 30th September. At only 11%, these attacks were much less frequent among cloud customers. However the number of cloud customers experiencing these attacks is rising quickly, more than doubling in one year.

Attacks using brute force increased from 30% to 44% of cloud customers but remained stable in on-premises environments at a high 49%. Vulnerability scans jumped dramatically in both environments. Brute force attacks and vulnerability scans are now occurring at almost the same rates in on-premises and cloud environments.

Web app attacks are more likely among cloud customers. However these attacks are down year-on-year in both cloud and on-premises computing, as are recons. App attacks increased slightly in both categories of customers.

The most prevalent types of attacks vary between on-premises and cloud environments. In on-premises computing the top three were malware (56% of customers), brute force (49%) and vulnerability scans (40%), while in the cloud the most common incidents were brute force, vulnerability scans and web app attacks, each of which affected 44% of customers.

[4] The incidents involving Alert Logic’s cloud-based honeypots varied in different parts of the world. Those hosted in Europe attracted twice as many attacks as honeypots in Asia and four times more than honeypots in the USA. This may be due to malware ‘factories’ operating in Eastern Europe and Russia testing their efforts locally before deploying them throughout the world.

[5] Chillingly, 14% of the malware collected by honeypots was not detectable by 51% of the world’s top antivirus vendors. Even more frightening: this was not because these were brand-new malware; much of the malware that was missed was repackaged variations of older malware and thus should have been detected.

The report concluded with a statement that security in the cloud is a shared responsibility. This is something that individual entrepreneurs as well as small and medium sized enterprises tend to forget.

In cloud computing, the service provider is responsible for the basics, for protecting the computing environment. But the customer is 100% responsible for what happens within that environment and, to ensure security, he or she needs to have some technical knowledge.


Advertisements by cloud service providers seem to imply that cloud computing is safer than an on-premises computing. This is simply not true. Both environments seem to be equally safe or unsafe viz-a-viz hackers and their malicious programs.

Attacks in the cloud are increasing as potential targets are becoming more ‘theft-worthy’. Thus, the security in the cloud needs to be just as robust as security in on-premises environments. However, you cannot rely solely on antivirus software vendors to detect all attacks.

Your best bet is therefore to enter an annual maintenance contract with an online computer maintenance firm that can periodically access your computer(s) from a remote location and ensure that it is protected as well as possible. This should not cost more than €120 to €150 a year depending on the number of computers you have.

Are We Always On The Computer?

A computer has been one of mankind’s greatest invention among other inventions ever since the foundation of science began. Its development was a result of years and years of long experiments spanning a hundred or so years conducted not just by one man, but many. Development of computers as it is today is a continuous process and it will ever be. Computers, however simple they may seem now to the computer literate, has a complex set of system underneath. It takes multiple disciplines in both computer studies and electronics to fully understand them. After all, computer in itself is subdivided into branches as is science itself.

While other technological inventions may have had already been developed prior to the foundation of science, “technology” is not yet a proper term for such. The word technology, after all, is always correlated with science and both science and technology are mutually inclusive to one another, strictly speaking in terminologies. Computers of today, however advanced they may seem, have had its origins in humble beginnings.

How did computer began?

Abacus, the earliest form of calculator, has been recorded to be in use since the early civilizations estimated to be around 1000 and 500 B.C., only to be adopted elsewhere in the world. The idea on how the algorithm of a computer does its arithmetic was based on this, in logic. Soon after, for as early as 1820’s, in the personification of Charles Babbage, dubbed to be one of the fathers of modern computer, developed ideas on how computers should do its math, initially known as the difference engine, it developed later after to become what is known as the analytical engine. While Charles Babbage, due to funding issues, didn’t get to see his ideas into fruition during his lifetime, it is his youngest son, Henry Babbage, who did so in 1910 based on his. However, this primitive form of computer is not as advanced as how we see on computers of today.

The idea of the need to do the computation on our behalf as man, hence the word ‘computer,’ came out of the need to handle complex problems and perform complex computations that is both difficult and takes longer time for man to handle. Especially true during the times of the industrialization era and great world war where the need for such arose. How a computer behaves is what’s in a library of a computer.

The development of computer grew by a lot since laying the foundation by Charles Babbage as was inspired by existing “technologies” of its time. From names of people of the past significant in the foundation of computers such as Ada Lovelace, Konrad Zuse, Alan Turing, John Atanasoff & Clifford Berry, Howard Aiken & Grace Hopper, so on and so forth, up to the present computer giant names such as William Gates, Steve Wozniak, and Steve Jobs, among others, computers of today are bigger in functions than they are their sizes and have found a spot in every people’s lives in both commercial and personal usage.

How do people use computers in their daily lives?

Modern day computers laid out the foundation on how we perform duties of today. It is a lot more efficient and makes the work done in shorter times. From a simple household leisure such is playing games or running multimedia programs, to doing office works, to a more difficult developing programs, up to a more complex computations such is done in NASA, computers made all this possible — all in a single box. What once takes a long time to finish in groups as in seen in companies without computers, can now be finished in shorter times with those.

Computers taking over the world

Also one of the most popular usage of computers is the internet. What once was the trend for telephones and telegrams, has become internet’s – and it is worldwide. Literally, computers taking over the world.
Although initially used for military purposes concurrent to the development of the computer, the internet grew up to become commercialized as it is used today. The internet, in conjunction to and other than the previous means, made communication around the world possible which also gave rise to communication tools such as the social media. To date, billions of people use computers with the internet every day.

Are we really too dependent on computers?

We may be are dependent on computers in relation to the internet given the information age we are in, since the computer age began. But such dependency was initially for a good intention – that is, to keep up with the demands of progress through the efficiency and rate the work demanded is done with computers as both our aid and tools. Let’s face it, there are complex works out there that can only be efficiently done if and only if we have computers. However, one should also ask whether such dependency is good for us. What if, by some chance, this technology called computers and the things it can do were taken from us? What then? Just like a bad addiction, computer dependency outside of our needs and moderation can be harmful for us, its users. An ideal tool for tyrants. While it may sound like it is out of context, it is not. In fact, we are as capable workers as our ancestors were without computers. Although obviously at a cost of the efficiency and ease we’ve known on how we do things with computers. These are not statements about abandoning computers as we know and use them, we’re just waking up with the idea of who we are without computers and who are ancestors were without those. No, we are not worthless without computers – we are not just as capable as someone who does and we alone are not capable as what a complex computer does as a computing machine. But do not be fooled, we are still the ones who made computers as they are today. In a way, we as a mankind is still superior to machines.

tips on Keeping Your Computer Cool

When your computer is on, nearly all of its components become hot. Constant exposure to high temperature can cause serious damage to your computer.

Here is a list of ways in keeping your PC cool.

Check if your fans are running.

This is the first step when you find your computer overheating. Open the case, and then check if all fans are still working. If at least one is not working anymore, consider doing repairs or getting a replacement.

Regularly clean your computer.

It is essential to regularly clean your computer, especially the cooling fans. The fans attached inside the computer case is used for active cooling of the computer. Over time, dust and dirt can accumulate in these fans. The accumulate dirt can slow down or, in worse, stop fans from working. If fans fail in expelling the hot air fast enough, some internal parts will eventually overheat.

To clean your cooling fan:

1. Shut down your PC.

2. Open the computer case.

3. If there is excessive dirt inside the computer case, take out the computer fan.

4. You can use compressed air, small electronic vacuum or duster, or damp cloth in cleaning the fan.

5. If you use moisten cloth, make sure that the cooling fan is dry or there is no remaining moisture before connecting it again.

Clean other computer parts as well such as the monitor, mouse, and keyboard.

Before cleaning any hardware component, make sure that your machine is turned off. Otherwise, your computer is susceptible to electrostatic discharge that can damage its parts and you are also prone to grounding yourself.

Before applying any cleaning procedures to hardware, make sure to check its manufacturer’s manual if they have provided you with the recommended instructions in cleaning or maintaining it.

Do not spray or spill any liquid directly in computer parts.

Do not limit the air flow around your computer.

Place your computer in a room that can provide sufficient air flow. Make sure that it is not sitting right next into other objects that prevent air circulation, like walls or other computers. There should be at least two to three inches of space on both sides. Since most of the hot air comes out from the air vent at the back end of the computer case, this part should be completely clear and open.

Move your computer to a cooler and cleaner environment.

Move your PC in a place with proper ventilation. It is important that the physical location will not contribute further heat to the computer. Make sure that your PC is not placed near a furnace, refrigerator, cooking appliances, and other things that can blow hot air or can transfer heat into your computer system.

To prevent your PC from overheating, it is advised to place it in an air-conditioned room.

Note: be careful when moving your computer in order to avoid damage on sensitive components inside it like the CPU, graphics card, hard drive, and motherboard.

Use your computer with case closed.

It seems logical to let the case open while the computer is running to keep it cooler. This is true. However, dirt and dust will accumulate and clog the computer fans faster when the case is opened. This can cause the fans to slow down or fail at cooling your computer.

Upgrade your CPU fan.

The CPU is the most important component inside the computer. When you are running demanding applications, the CPU and graphics card induce more heat. It can get so hot that it can be cooked.

Consider purchasing a high-quality and larger CPU fan that can keep the CPU temperature lower than the pre-built CPU fan in your computer could.

Consider installing a component-specific fan.

If you have observed that the other components are overheating, install a component-specific fan to cool them down.

Consider installing a case fan.

This small fan can be attached to either the front or back of the computer case. There are two types of case fan: one that can draw cooler air into the case, and one that can expel warm air from the case. Installing both is a great way to cool your computer.

Turn off your computer when not in use.

A computer continues to produce heat as long as it running, even if you aren’t using it. If you will only have a few minutes of inactivity, at least set your computer to hibernation. Basically, it will also turn off your computer but the opened files and programs are stored in your hard disk.

Also, unplug external hardware of no longer use like printers and scanners.

Overheating can destroy and shorten the lifespan of components inside your computer. The major upside of keeping your computer cool is that it can help you avoid expensive repairs or unnecessary upgrades.
