Introduction
Computer forensics is the practice of collecting, analysing and reporting on digital information in a way that is legally admissible. It can be used in the detection and prevention of crime and in any dispute where evidence is stored digitally. Computer forensics has comparable examination stages to other forensic disciplines and faces similar issues.

About this guide
This guide discusses computer forensics from a neutral perspective. It is not linked to particular legislation or intended to promote a particular company or product and is not written in bias of either law enforcement or commercial computer forensics. It is aimed at a non-technical audience and provides a high-level view of computer forensics. This guide uses the term “computer”, but the concepts apply to any device capable of storing digital information.

Uses of computer forensics
There are few areas of crime or dispute where computer forensics cannot be applied. Law enforcement agencies have been among the earliest and heaviest users of computer forensics and consequently have often been at the forefront of developments in the field. Computers may constitute a ‘scene of a crime’, for example with hacking [ 1] or denial of service attacks [2] or they may hold evidence in the form of emails, internet history, documents or other files relevant to crimes such as murder, kidnap, fraud and drug trafficking. It is not just the content of emails, documents and other files which may be of interest to investigators but also the ‘meta-data’ [3] associated with those files. A computer forensic examination may reveal when a document first appeared on a computer, when it was last edited, when it was last saved or printed and which user carried out these actions.

If you want to remotely have access to your central organizational network, you may want to consider using a virtual private network (VPN). Although the name sounds very complicated, it is actually quite easy to use. This private network largely uses public telecommunication such as the internet to provide access to a central organizational network. This simply means that a computer can connect to another computer on the same network. With this private network you may share data and have access to network resources, printers, databases, websites, etc.

The benefit of a VPN is that there are low costs involved because it does not need physical leased lines to connect users remotely to an Intranet. The world has slowly evolved into a modernised wireless technological era. Businesses are at the advantage point and grow in capital because of smart technology and software. Virtual Private networks are faster, secure and reliable when you want to share information across computer networks. People who are traveling, sales persons, companies with many shops, offices or businesses around the world benefit hugely from this fast network.

You don’t have to worry about how safe the network is. A Virtual Private network is safe and secure, because only users with access can read the data, thus anybody else who intercepts the data will only be reading encrypted data. Privacy are ensured through security procedures and tunnelling protocols. Not only are the data encrypted, but also the originating and receiving network addresses are encrypted. Data that are send through these “tunnels” are encrypted and only the sender and receiver can read the data. Businesses wishing to grow can expand all its intranet’s resources to employees working from remote offices or their homes securely. The ultimate aim of your VPN is to grant secure access to the organization with equal resources at a better price.

Like a lot of people in the world today, you probably have a specific budget in mind when you buy a desktop computer. You may wonder, though, how to pick out the computer. What size and shape you need and with all the new technology out there, you may be unsure what to get. We are here to help you with this most difficult decision. Read on for some great insight into what to look for when purchasing a great desktop computer.

There are four different types of a PC user. Read below to find out which one you are. This will help you choose the best computer for you and your family.

General purpose user: a general purpose use desktop computer is perfect for those who like to make pictures, edit pictures, play games and surf the net. Depending on what you need a general purpose computer can range in price from $500 to $1500.

Power User: a power user computer is a computer that can be used to make and edit movies and videos. These types of computers also allow you to make digital designs and play mega games. With these computers you will typically need 2 or more hard drives and a great graphics card. These computers typically run higher in price due to the power behind the computer and the different running systems that it will include. A power user computer can range in price from $2500 to $3500 depending on what you will need to perform the types of work that you want to do on this computer.

The world is growing very fast and technology plays the most important role regarding the development of the human society on earth. From the very beginning of technological advancement, it is found that some nations are technologically advance compare to the majority of nations.

For the last several decades, computer technology is getting the most priority for human civilization. Right now, laptop or computer is considered a part of human life. Without laptop or PC, it is very hard to pass a day.

There are many countries, which produce computer or laptop but most of the countries in the world are still far behind to produce their own laptop. Many countries are trying to develop computer technology for their own uses because they want to develop their new generation technologically. If they have their own production, they can serve cheap laptops to their general people.

Bangladesh is a developing country, and most of the electronic products are imported from China or other developed countries. As the demand of laptop or computer is growing very fast, and most of the people want cheap products, Bangladesh government decided to assemble laptop with their own technology. Doel is the first laptop brand in Bangladesh.

Doel is a Bengali word. This is the name of the national bird of Bangladesh, and the brand is named after Doel bird (Oriental Magpie Robin). This is the widely used symbol in Bangladesh. The laptops are assembled by Telephone Shilpa Sangstha.

The producer aimed to provide cheap laptop to the general people of the country. As most of the people live in rural area, and their income level is not so good to buy other brand laptops, so this cheap laptop will be a great source for them.

Computers are practically in every aspect of our lives these days and our reliance on them is heavy. They are used as tools for work, data storage, schoolwork, shopping, and entertainment. Because so much information is typically stored on our computers we must always make sure they are protected from that loss of information. Businesses have to secure information on their computers to protect it from exploitation by hackers. And the home computer user is no exception to the requirement to protect computer information because there can be credit card numbers, social security numbers, and other sensitive personal information stored on their computer or transmitted when doing online shopping. There is a term used for this and it is “computer security risk.” This term refers to the likelihood that some action could cause the loss of information, computer hardware, or denial of service.

When computer security is put at risk intentionally, it becomes criminal in nature or we call this a computer crime. Another relative of the computer crime is the cybercrime. The FBI pays especially close attention to cybercrimes and there are other types of crimes related to them such as corporate spying, unethical computer activity, cyberterrorism, hacking, cracking, and cyberextortion.

Hacking at one time had a positive meaning to it but since computer crimes were introduced, it falls in the bucket with the rest of them. The hacker is the person who gains access to a computer network illegally. They sometimes use the excuse that they were only trying to break a network’s security so as to make the administrator aware of any security deficiencies.
