What is the security key to connect to the access point?

I am assuming you are referring to a wireless access point (WAP), if this is wrong, please restate your question with more clarification.

A wireless access point usually connects a wireless device to a wired network. In some instances it establishes connections between two wireless devices, but this is a much less common way to use an access point. Either way, it is usually in the form of a WiFi (802.11 protocol) router or bridge or Bluetooth device. While few Bluetooth devices has any kind of security key, most wireless routers can be configured to require a password or passphrase to connect to it. The router may ship with a default password, but the person setting it up can log onto it and set a new password. Some wireless routers also connect to an authentication server which provides additional authentication, a user can connect to the access point, but until they have authenticated via the connected authentication server, they cannot access the network the wireless router is connected to.

Which encryption algorithm is better and why?

If you're talking about symmetric key encryption (the kind where you just use one key for encryption and decryption), then arguably, the best encryption algorithm you can use is the Rijndael algorithm, better known now as AES (advanced encryption standard). It is the encryption standard used by the U.S. government for classified information. It is fast, requires little memory, and the only potential attacks against it are highly theoretical.

Rijndael beat out Twofish and Serpent in the AES standard contest, but those other two algorithms will provide more than enough security as well. In the end, it doesn't really matter, since most successful attacks are made simply by finding out your key through brute force, espionage or extortion, rather than pure data analysis.

Humans are almost always the weakest point when it comes to security, and it doesn't matter what algorithm you use if someone can guess your password.

What is calculated control in Access?

It contains data that has been calculated from other data. So it could be a text box that shows a total of two numbers in two other text boxes for example.

Where can you find FREE computer monitoring software?

Answer

A great place to go is download.com and search for AVG 9 Free. AVG is award winning, free and it is used by over 80 million users. What makes it so great is that Grisoft (the people who make AVG products) decided to give anti virus protection to users for free. Before I upgraded to AVG Internet Security, the free version got rid of countless infections. The only difference between the free and paid version is the paid version (Internet Security) includes a firewall, anti rootkit, anti spam, web shield.

Here's a link to the page I was talking about. The one you want is the second result

Why is it important to have encryption in a digital world?

What is the difference between an expoit and vulnerability in information security?

A vulnerability is a weak point in a system. This implies a risk, especially to confidential information.

An exploit is a means of taking advantage of the vulnerability and using it to take advantage of a system or network.

Just because something has been identified as a vulnerability doesn't mean that it has been used to compromise a system. The presence of the exploit means someone has successfully used that weakness and taken advantage of it.

5 characteristics of computer?

The major characteristics of computers are the following:

  • Speed : A powerful computer is capable of executing about 3 million calculations per second.
  • Accuracy : A computer's accuracy is consistently high; if there are errors, they are due to errors in instructions given by the programmer.
  • Reliability : The output generated by the computer is very reliable as long as the data is reliable.
  • Memory/Storage Capacity : The computer can store large volumes of data and makes the retrieval of data an easy task.
  • Versatility: The computer can accomplish many different things. It can accept information through various input-output devices, perform arithmetic and logic operations, generate a variety of outputs in a variety of forms, etc.
  • Automation: Once the instructions are fed into computer it works automatically without any human intervention.
  • Diligence: A computer will never fail to perform its task due to distraction or laziness.
  • Convenience: Computers are usually easy to access, and allow people to find information easily that without a computer would be very difficult.
  • Flexibility: Computers can be used for entertainment, for business, by people who hold different ideals or who have varied goals. Almost anyone can use a computer, and computers can be used to assist with almost any goal.

How did early computer security work?

When I hear the word "early computer security, all I can think of are human security men with guns, trying to protect the first huge computer from thieves trying to steal it. At that time, I don't think they were worrying about viruses as compare to real people stealing the computer which can take up to 6 people to carry. Then, I think people were the Virus you'll need protection from.
