Computer Security

Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.

DNA computing, also known as molecular computing, is a new approach to massively parallel computation based on groundbreaking work by Adleman . In November of 1994, Dr. Leonard Adleman wrote the first paper on DNA computing. In this paper, he found a way to solve the "Hamiltonian path problem," which involves finding all the possible paths between a certain number of vertices. It is also known as the "traveling salesman problem." This name comes from viewing each vertex as a city, with the problem to find all possible routes for a salesman passing through each of these cities . Computers today all use binary codes - 1's and 0's or on's and off's. These codes are the basis for all possible calculations a computer is able to perform. Because the DNA molecule is also a code, Adleman saw the possibility of employing DNA as a molecular computer. However, rather than relying in the position of electronic switches in a microchip, Adleman relied on the much faster reactions of DNA nucleotides binding with their complements, a brute force method that would indeed work A DNA computer is a collection of DNA strands that have been specially selected to aid in the search of solutions for some problems. DNA computing results in parallelism, which means that when enough DNA information is given, huge problems can be solved by invoking a parallel search

Upper and lower case letters. And numbers. And it is long.

Well when you update your computer it will secure your computer because windows has found errors. Sometimes there are back doors in Windows and Microsoft will send out updates to fill in that back door, so no one bad gets in. Just make sure your computer is up-to-date and make sure automatic updates are on. The Service Packs are packs of updates, almost like a mini operating system. Also, clean your computer for best performance.

Simply asking hp is a very broad statement. Its not who's its by its what format it includes. What operating system it uses. This are the components that are going to decide it. In my opinion Yes you can a a fingerprint reader to an hp laptop in most cases. But I won't do it because it is very costly and sometimes people can not log in because of some accident.

A web firewall usually has a least of hundreds of bogus, and malicious URL or websites. If it comes across a website that is on the least than it will inform the PC user of the dangerous content before he or she actually visits it. Most firewalls in schools and business block sites by their content not by their name. this is how it works an administrator configures the firewall to block certain categories of websites. Some commonly blocked websites are audio and video sharing, proxy servers and ofcourse adult video. Firewalls are helpful when it comes to protecting your computer and the people who view it. But it is also sometimes bad. Firewalls sometimes block some sites like youtube, sites like this one and gaming. The best method is knowing what your needs are and how to configure the firewall to let you do this. Firewalls slow down performance a little but its worth it.

In encryption, a key is the information used to encrypt the data. 128 bit means that the key is 128 bits long (a bit is a single unit, or "bit" of data, either 0 or 1). The longer the key, the more complex the encrypted data becomes. 128 bits is considered a strong key length.

Information systems are a network of computers linked to perform many different functions in business. Information systems connect the accounting, marketing and information technology departments.

usualy when you go to login to a website there is something at the bottom that says forgot password? you click on that and fill out the info then they send you an email.

E-saftey is all about being safe e.g. don't meet people who you don't know and don't see people who you don't know.

Installation of a firewall can give a false sense of security, because many users do not understand the limitations of a firewall. Specifically, a firewall primarily defends against unsolicited incoming attacks: a hacker tries to access the internal network from the outside.

Firewalls often fail to effectively protect from threats from the inside: viruses (malware of all sorts, worms, etc), once active on the inside, may be able to spread within the network, and spawn network activity that traverses the firewall in both directions.

Definitely not Norton or Mcafee, If you want one that is not a computer hog and has good rock solid protection try PC Tools Internet security or AVG Internet security. They are both good and i have had no problems with either of them.
