All daily tasks such as communication through emails &messages, writing documents, preparing presentations ,and maintaining a record of things, many of which were accomplished manually, are now performed efficiently & quickly through the aid of laptops and personal computers.

Everyday our life, it has become necessary for both individuals & businesses to acquire laptops and computers with the specification that can fulfill their specific requirements . However, buying a laptop and computer is a long-term investment which is not affordable for many .Furthermore, laptops and computers cannot be considered as an investment as they need to be replaced every few years as new technologies and novel features surface in the market.

As it has become practically impossible to connect the world accomplish daily tasks without a laptop and computers, both individuals and business are making the cost effective and budget friendly choice of renting laptops and computers instead of investing buying the latest technology. Renting gives one the freedom to choose from a wide variety of laptops& computers , acquire them for a short term or long term duration depending on one’s requirement & replace them for a new version without bearing the cost obsolescence.

Top Five reasons why renting laptops & computers wise

  •  Get desired laptop with limited financial reserves
  •  Predict your monthly expenses and get rid of maintenance costs
  •  Update to the latest technology
  •  Organize business meetings hassle free
  •  Spend money where it is most needed

Therefore, renting laptops and computers is the smarter choice for ensuring long term personal and professional growth as opposed to engaging in mindless consumerism that promotes the unidimensional concept of “happiness only be bought.”

Most of us know the drill of pulling up our antivirus software and running a quick system scan or relying on other built-in security protections that come pre-loaded onto our devices, but antivirus software and Windows Defender are not the only things which can keep your computer protected. A huge determining factor in whether or not your computer will get malware is knowledge. Knowing what to be on the lookout for and how to protect yourself beforehand during your daily computing time can and will save you from a whole lot of headaches in the future, so here are four computer security threats you may not be aware of.

USB Drive Malware and Viruses:

Malicious attacks can happen very quickly if a nasty USB stick should be plugged into your computer by you or someone else. Studies show that more than half of people will readily plug in any random USB drives we find just to see what is on there. Modern versions of Windows and mac no longer run executables on USB drives by default, but the most advanced malware can get around this.

The best way to stay safe is to be careful with what you plug into your computer. If you do have an antivirus package installed on your computer, it might already have some kind of USB drive protection available, so make sure it’s correctly configured and switched on. Otherwise, run a thorough virus scan on any new drives when you attach them.

Webcam Hacking:

The easiest way to keep hackers out of your webcam is just to tape over the camera or use the built-in shutter. There is also some software tweaks you can make too. In Window, open up Device Manager, right click on your webcam and then choose Disable. In Windows 10 you can choose Privacy then Camera to pick which apps can and can’t use the webcam.

Insecure WiFi Connections:

Even if you’ve got all your data safely locked down on your computer, once it’s beamed out into the internet it can be nabbed by someone else with surprising ease. We’re talking here primarily about public Wi-Fi networks, where you’re sharing your access with a coffee shop or hotel full of other people.

Here are some steps you can take to stay protected; stick to sites that use secure HTTPS connections (usually signalled with a green padlock in your browsers address bar), install a VPN (Virtual Private Network) to add an extra layer of encryption and protection.

Social Media Attacks and Pop-ups:

In terms of computer use, being suspicious of emails and messages that pop up over the social platform, thinking twice about following through on pop-ups and prompts on your system, and being very careful about the information you cross paths with, whether that’s over the social media, in person or over the phone. Also, look out for phishing attacks.

Firewall support
By admin / General / 0 Comments

Firewalls are easily considered one of the most essential features of security for your computer. A firewall is a network security system that controls the incoming and outgoing network traffic based on the applied rule set. A firewall establishes a barrier between a trusted, secure internal network and another network (e.g., the Internet) that is assumed not to be secure and trusted.

Why do you need a firewall? Today’s firewalls secure services and connections in your home or office network. When you connect to a public Wi-Fi connection, some services and connections will be blocked by the firewall. What is blocked and what is allowed is dependent upon how the firewall is configured. Blocking those connections is vital to your computer’s security.

Hardware and Software Firewalls
The hardware firewall in a broadband router is primarily concerned with keeping bad stuff from the outside from getting in. The limitation of this type of firewall is that it typically treats any kind of traffic travelling from the local network out to the Internet as safe, which can sometimes be a problem. For example, if your computer has a malicious program that sends out spam messages, a hardware firewall would not stop that from happening.

Software firewalls run on the computers individually. A software firewall is able to take a closer look at malicious traffic and intercept it before it leaves your computer. According to Microsoft, the most effective and important first step you can take to help protect your computer is to turn on the Windows firewall. If you have more than one computer connected to a network, it is important to protect every computer. You should have a hardware firewall (such as a router) to protect your network, but you should also use a software firewall on each computer to help prevent the spread of a virus in your network if one of the computers becomes infected.

This technology is really nothing new. It’s just based on the basic physics concept of resonance. When two entities are vibrating at the same frequency, they exchange energy, even if they are not in direct line of sight. This means with a transmitter on one end and a receiver on the other, energy could be transferred to an object. As the energy builds, it produces usable voltage. So a light bulb can be lit from across the room without being directly connected to a power source. All that is needed is a transmitter and a receiver. Its the same idea as the opera singer shattering glass with her voice.

So this concept could be brought to the wireless world that is becoming more and more prevalent. Recent studies have been done at the Massachusetts Institute of Technology and are showing a 40% efficiency rate with wireless power transmission, but could become more efficient as time goes on.

Ideally, a laptop could be powered from across entire rooms, regardless of what obstructions were between the transmitter and receiver, by being charged constantly without being plugged in. That means laptops could be charging while in range of the transmitter at all times. If the laptop stayed in the room, then it might not even need a battery. This could end the use of having to charge laptops by plugging them into an outlet, it could even replace batteries. No batteries would be cheaper and devices such as laptops could be made lighter and smaller.

Some people have presented the caution that broadcasting energy to power electric devices could, in turn, have a negative impact on people’s health. Powerful radiation can be hazardous to people’s health, but with the use of resonance coupling, wavelengths produced would be longer, which would be no more harmful than being exposed to radio waves.

This will be an interesting technology to keep an eye on in the years to come.

32bit cpu,64bit cpu

We always look for better configuration whenever we purchase computer or laptop for our personal use; there are so many things we have to make sure while buying a computer like RAM size, CPU, the storage capacity of hard disk and processor as well. We always want to have latest specifications and better processors; if you’re using windows on your computer then probably you have noticed that in your windows you have two program files folders in which one is “Program files” and the other one “Program Files (x86)”.Mainly to store the DLL files of 64-bit applications the folder “Program Files” is used and to store DLL file of 32-bit applications the folder “Program Files (x86)” is used which is one of the major differences you can notice while having 32-bit or 64-bit processor assembled in your system. We hardly pay our attention towards this little piece of information but when it comes to performance and efficiency then these little things makes much difference.

What is the 32-bit processor?

We all have been using a 32-bit processor which is known as the primary processor in all our computers, every single processor manufactured by Intel and AMD in early stages were 32-bit. All the operating systems and different software used in 32-bit processors mainly work with data units that are 32 bits wide. Some of the most common operating systems like Windows 95, 98, 2000 and XP are 32-bit operating systems. The computers which have 32-bit processors cannot use 64-bit operating systems; you can install only 32-bit operating systems on that PC.

What is the 64-bit processor?

The first 64-bit computer was manufactured by IBM and its name was IBM 7030 stretch supercomputer, but only in the early 2000s, we have started using 64-bit processors. Even Microsoft has introduced a 64-bit version of Windows XP which is compatible to use with 64-bit processors only after the 2000s. Other popular operating systems also capable of working with 64-bit processors are Windows Vista, Windows 7 and Windows 8, which mainly works with data units that are 64 bits wide. You can even install the 32-bit operating system on a computer which has a 64-bit processor, but it will not work with its full capacity when you don’t install the 64-bit operating system on a computer which has a 64-bit processor.

The main difference between 32 & 64-bit processors

The biggest difference between 32-bit and 64-bit processors is the speed with which they can perform calculations, 64-bit processors work on much faster speed as compared to 32-bit processors. Even 64-bit processors come in dual core, quad core, six core and eight core variants which are mainly used in computers manufactured for home use. With multiple core processors, you can expect an increased number of calculations per second and also much faster-processing speed, which makes your computer runs at a faster speed. Today, we use programs that require faster calculations and processing which we will get only from 64-bit processors.

Even 64-bit processors support more RAM than 32-bit processors, at one end 32-bit processors support only 3-4GB of RAM whereas 64-bit Processors are designed to support 4GB RAM or above as well. So if you need to run applications that require more RAM like graphic design, video editing and engineering programs you need to have 64-bit processors installed in your desktop before installing this high-performance software. But in case if you need to run high graphics game you don’t have to upgrade your processor as you need to have a high graphics card instead of the better processor.

Conclusion

At present we all are using 64-bit processors as almost all computer manufacturers are installing 64-bit processors in their PCs, 64-bit processors are cheap as well and deliver better performance, so it is more profitable to buy 64-bit processor instead of 32-bit processor and soon every computer retailers offer only 64-bit processors in upcoming time. So we finally conclude that 64-bit processors are much better than 32-bit processors and with 64-bit processors, you can expect better performance with multiple layers in it. If we simply calculate the working speed of 64-bit processor than 64-bit processors can access over four billion times the physical memory of 32-bit processors which is a huge difference.
