computer-performance

Many computer users think that slow performance of the computer means that it has already served its time and they just need to get a new one. Actually, slow performance is a result of long usage without taking care of your computer and. There are some easy ways how to improve the performance of your computer noticeably. If you follow these instructions, your slow computer will work as new one.

First thing you need to do is scan your computer, using antivirus program. If you don’t have an antivirus program, download it. Better invest some money in good antivirus software to make sure your computer will be totally free of all the malware and other threats.

How to avoid computer viruses and other malware

malware

One of the biggest threats to computers is viruses and other malware. They can be very dangerous and some of them lead to data loss and identity theft. Unfortunately it is possible to catch malware from some very simple daily actions. The good news is that there are some very effective ways how to prevent them.

One of the most effective methods is safe browsing. That might sound very simple and reasonable, but many internet users don’t know how to avoid all the malware completely. Experienced internet users know that it there is possibility to get some serious viruses by clicking on adds or pop-ups, but not every threat is so obvious. Better don’t click to any ads at all and avoid from unknown, suspicious websites. Luckily most of the internet browsers protect you from possibility to get infected, but make sure your browser is configured to always ask the users permeation before running files and downloading something automatically.

You can also block all these ads and pop-ups, because it is also possible to click on them by an accident. For example, usually there is a close button to the pop-up ad, but by licking it, you actually open the ad. Better use the Ad Block or other extensions to reduce the amount of these misleading pop-ups. They can be very dangerous so better configure your internet browser to block them.

Make sure you are using safe internet browser that is always up to date. If you are using older browser, be prepared that it won’t be so advanced and you might catch some viruses. There are no program extensions that protect your computer. Such browsers as Google Chrome, Mozilla Firefox and Safari are considered as safe, so better choose one of them.

Be very careful with downloads. Better download only programs and files that are really necessary and use only reliable, official websites for that. Also read the download agreements. Downloading unknown programs and files is the easiest way how to catch some very dangerous viruses.

Never open suspicious e-mails or messages in social media. Also that is very popular and easy way how to catch some viruses. Never download attachments if you are not sure about their content. If there are some e-mails that don’t look safe, just delete them as soon as you see them.

And the last and most important advice would be to buy reliable and good antivirus program. If your computer and all the files in it are important for you than better don’t try to save money on this. Buy a real program, instead of using free demo versions that are not protecting your computer fully. That will protect your computer even if you will skip all the previous conditions.

Desktop vs laptop

laptop-desktop

Nowadays desktops are losing their dominance. If few years ago they were considered as faster and in many ways better than laptops than nowadays laptops are as capable as desktops, only smaller and more convenient. Despite of that, some people still prefer desktops. To understand which type of commuter is better, we evaluated them by different criteria.

A first criterion is the price. The prices of laptops are reducing over last few years, because of development of technologies. It is even possible to get a laptop that coasts less than 200 EUR, but average prices of good laptops are higher. Desktops also are becoming a bit cheaper. So if we compare desktop and laptop with the same parameters, desktops are still cheaper, however, you will need to buy monitor and keyboard as well. If we compare full configuration of both types of computers, the price difference is insignificant.

If we evaluate portability, of course laptops are lot superior. There is no question about that, but also desktops nowadays have become a little bit more comfortable for portability. They are smaller and lighter than they used to be several years ago. Of course it is still not possible to use desktop from any place, like it is possible with laptop.

Also the variation of components is very important and from this aspect desktop is a lot better choice. It is possible to recruit desktop with all the components you need. For example if RAM is very important for you, but video card is not, you can get the desktop with the biggest RAM, but average video card. Laptops are already recruited and all the components usually are about same level. If you have some special demands, than it is lot wiser to choose all the components separately.

The possibility of upgrading is another aspect where desktop is superior. Almost any detail of desktop can be easily removed. If within the time of usage occurs a need for some upgrades, it is always possible for desktop. Also if something breaks, you can easily change it to new one. With laptop it is lot more complicated. Then you must dismantle the whole device and also the details for desktops are more expensive. If the computer is meant for longer time then only few years, then desktop could turn out to be a lot better choice.

The physical maintenance of the computer is also easier in case you are using desktop instead of laptop. You can easily open the cover of the desktop and clean it from dusts. Laptop again must be dismantled and so most of the users can’t do it by themselves.

So there are some aspects where desktops are still superior. There is no common answer to the question – which one is better. They both have some pros and cons. The choice must be made based on each user’s priorities, needs and wishes.

How to buy the best laptop?

laptops

There are so many options, when it comes to buying a laptop and it can be quite challenging to buy the most appropriate one, if you have no clue what specification is the most important for each user. So here is a little help for those who are looking for a new laptop.

First thing you have to do is to determinate your needs. Laptop can be used for many purposes and it cardinally affects the right choice. For example, computer can be used for office or school work, media production, gaming, internet etc., so when you are buying a laptop, keep in mind your basic needs.

After you have realized what you need, you have to start evaluate computers. First and the most important thing to choose is the right platform for example, Mac, Windows, Chrome OS etc. If you are not familiar with all these platforms, that’s going to be a hard task, but we will give you a short summary of three most popular platforms. Windows is the most popular platform and it works to lot more computers than any other platform. The latest version is Windows 10 which has many improvements comparing to previous ones. Windows 10 is easy to use and it has all the functions needed. Mac is similar to Windows, only with different design and some varied functions. Although all MacBooks come with operating system inside, it costs more than computer with Windows. Chrome OS looks almost like windows, only the main app is Chrome browser. The biggest issue with Chrome OS is that there are not many offline apps that work well. Good thing is that Chromebooks work very well if you use them for web and they are inexpensive.

Then, of course you need to check main computer components. First one is hard disk. That is the place where all the files will be stored. For average user 500 GB would be enough, but if you are planning to keep a lot of videos, pictures, programs, music, documents etc., on your computer, you will need bigger hard disk.

RAM or memory is storage, but it is needed for programs use to keep temporary information. If you have small RAM, programs can work improperly. For average user 4GB is enough, but if you are buying computer for games or media production, you will need a bigger one.

CPU or the processor is responsible for overall operation. The most popular processors are Intel and ADM. Intel is more expensive, but in almost every case it works a lot better. For average usage 2, 3 GHz Intel processor is enough.

Video card is not so important aspect if you are using your computer for work or web, but if you are gamer, then you need to buy the best possible video card. For other computer users almost any video card will be fine.

For desktops, also display quality is very important, because you can’t just buy a new monitor if the old one is not good enough. The more pixels you have, the sharper the image will be. The most popular display quality is 1366 x 768, but if you are planning to edit some pictures or make videos, better quality could be helpful.

Next thing that has to be taken into a consideration is the size. That is very important aspect, if you have to carry it with you a lot. Most popular size is 15 inches. It’s appropriate size for carrying around, but probably you will need to buy a laptop case for that. If you buy smaller laptop, you can carry it around lot more easily. Bigger laptops are not so comfortable and they are more suitable for static usage.

The last important thing is the durance of the battery. If you are using your computer without charger a lot, it should have at least 6 hour durance, although longer durance is always better. The best way how to know, if the battery is good enough, is to read reviews, because descriptions can lie.

How does a computer work?

how-does-computer-work

Lot of computer users doesn’t know anything about the processes addressed into the computer. They push buttons and see the results of that but have no idea how it is possible. On one hand average computer user doesn’t have to know everything about computers system and operations, because it is complicated and it is possible to learn to use the computer without all of that, but on the other hand this knowledge can help to deal with problems almost every user has to face with sooner or later. Here are some basics of computers work.

When you press the start button on your computer, there is a signal sent to the computers power supply, which provides the conversion of the current. In simpler terms, it provides the computer with the electricity in needed amounts. If there are no problems with the electricity supply, the computer sends signals to the motherboard and processor. At the same time the processor clears unnecessary data in the memory registers and gives program counter to the processor. Program counter is a hexadecimal number which is the location of the first instruction. It gives a signal to the processor that it is able to process the instructions of the basic input/output system.

The operation of the basic input/output starts with, to make sure that every component of the computer is working properly. If something is wrong, you will probably hear a beep or other signal that will let you know computer is not in working order and the computer will not turn on properly. If everything is right power on self test will go through some systems and the operating system will starting to load.

So after the power on self test, computer will start the boot process. That means the loading of operating system and associated files. These processes are different for many operating systems, but the basic principles are about the same – the operating system loader is found on the boot sector and it gives a signal to the computer to start the loading of registry. After that the loading of many programs starts that make up the operating system into the memory. When the registry and all the programs are loaded, operating system can be started.

If operating system is loaded properly it must communicate with processor. That is possible because of interrupt request. This request has been sent every time hardware needs to provide the communication with the computer. After request has been sent, processor stops current works and processes the request. All the previous actions of processor are stored in the memory.

Then it is possible to work with the computer. Each operation (pressed button) is another request that computer complies. Computer must carry out multitudinous operations every second.

Computer Security Policy

computer-security

When working with the computer, it is very important to comply with the computer security. Every computer user should know how to keep it safe. Although every computer system provides the basic safety aspects, computer user needs to know how to use it correctly and avoid loss or theft of any files.

Basically there are two types of computer security. One is brake-in security and the other one is data security. Brake in security means usage of security software and all the passwords to the files and systems so unauthorized persons couldn’t access them. Data security however means to have a good backup system, so the data wouldn’t get lost.

If we are talking about break in security than the best way how to avoid any attacks is to use security software that updates automatically. Every day hackers come up with new ways how to attack to the computers, so the security system always has to be updated to the latest version. Every security software can be set to do it, but make sure yours have the correct settings. Also it is recommended to set the internet browser to automatically updating.

The security software also should be bought from a well-known company. Don’t buy or get free security software from pop-up messages or untrustworthy e-mails. In best case these software just won’t work, but in the worst case they will work the opposite way – will let to hack your computer.

Also it is very important to protect all the files and systems with passwords. Passwords have to be strong so anyone couldn’t just guess them. For average user password with 10 characters is appropriate beside any password should contain random letters and numbers not some meaningful words or dates. Each account should have different password, so in case someone gets it, he wouldn’t be able to access all files. Never give your passwords to anyone, even if you trust them. Also be cautious when you type your passwords so anyone can’t see them.

If we are talking about data security, then it is all about users preventive actions. Every user needs to make sure they can restore the files if something happens to the hard disk or other file storage. That can be done in several ways. One is to back up files in other media for example zip disk or CD-ROM. If hard disk crashes, it is possible to repair the disk and after that restore the information from the backup media onto the new disk. However this is not the easiest way.

Nowadays it is possible to save huge amount of files into removable disks – USB flash drives, SD cards etc. All the files needed can be stored into these removable devices and incase of any computer crash all the files will be safe. Just make sure, anyone else can’t get these devices, especially if the files are important. Another good way is to storage files into online clouds.
