Computers Running Speeds : What influence it the most ?

Monday, January 28th, 2013

If you are experiencing a slow running computer, then the likelihood is that you are very stressed, let’s face it, nothing is more aggravating than a slow, immovable computer screen. It leaves you shouting at it, and getting a headache, and really it does nobody any good. For most people this is it, they will end up buying a new computer of laptop, and crush this old forgotten computer. But, little do they know, they could of spent a little or nothing on fixing it, and have made it quicker than the new computer they have already gone and purchased.

What you should so first, is try and manually fix your computer, now, do not fear, you don’t have to be technically savvy for this at all. All you need to do is follow these instructions and you will be fine. First, go to my computer, then right click over the local disk C. Then hit properties, you should then see a pie chart showing used space and free space. Then bellow that, a tab button should appear saying disk cleanup. Click that then wait for a new window to open. When it does, make sure all the boxes are checked with a tick, and then hit ok. Then a computer prompt will appear about deleting these files, you click ok.

What you have just done, is deleted all the unnecessary files from your computer, the ones that mean nothing, and are clogging up your hard drive with useless files, which slow down your computers performance. This is just part one of house keeping you can manually do to speed up your computers performance.

Secondly, you need to go to tools in the properties screen from your local disk C. Then hit defragment now, this will make all those files you deleted usable again, whereas before they were useless and clogging up the computer, now they are able to be used properly, and will appear as free space on your computer, and as computers run quicker when more memory is available, your computer will appear to have an improved performance, and you won’t go red in the face any more shouting at it. Do this about once a week, so that you can effectively and manually maintain your computers smooth performance.

If this isn’t what you had in mind, there are a number of other ways you can improve your computers speed. Some computer parts such as RAM and optional storage devices can hold files and improve your computers memory, so that your computer is able to perform many more tasks. Overall, computers run quickly when they have lots of memory available to them. Some people have huge memory devices and hard drives they use, as they need them for work, or large amounts of data. A head computer or server at a business should always have a great amount of memory installed, so that it always performs well, and never goes down. Other people store many films, pictures and music files on their computer, so they need lots of memory to perform the tasks commanded by the user..

Using Firewall to Protect Your Computer

Friday, June 24th, 2011

Why do you need to protect your computer with a firewall? Does a firewall really help? A firewall is a program or hardware that provides your computer protection from anonymous hackers, worms, and viruses that try to invade your computer through the Internet. It is a barrier that protects your computer. The firewall scans the things that go through your Internet access point to filter your computer from anomalies based on how you customized the settings.

A firewall’s task is tantamount to an actual, physical firewall which keeps fire from spreading to other areas or even your home.

When using your computer at home, or you have a network of computers, or you are using your computer for business, it is essentially important to turn on your firewall. The firewall has two variations. One is hardware and the other is a software program. The hardware firewall is a piece of electronic device which is usually used by businesses handling large networks. Computers used at home usually use the software firewall.

The firewall is needed especially if you have a DSL service or a cable modem for Internet connection. But, having your firewall turned on does not mean you are completely and fully protected from hackers, worms, and viruses. The firewall will not always block virus in emails or malwares from attacking and infiltrating your computer. You also need to have updated antivirus software installed in your computer to double the security and increase the protection.

Firewalls use different combinations of the three ways to control the inflow and outflow of traffic in the network:

Packet filtering refers to the analysis of small chunks of data. The firewall scrutinizes the header information which holds the source, destination IP addresses, and the ports. Packets or small bits of data that pass through the filters are sent to the requesting system while all the other data are rejected.

Proxy service. In the proxy service, the information or data from the Internet is reclaimed by the firewall and launched to the requesting system and from the requesting system to the firewall.

Make sure that your computer runs with a firewall. If you can, you should also try using an all-in-one security suite such as an antivirus firewall software program that works both as virus protection and firewall. .
