A computer system is the combination of hardware and software. A typical computer system has memory and set of states that define the relationship between the systems inputs and outputs.\n\nAlthough in earlier times the personal computer or PC was an example of a computer system, in practice a person considered a Computer Systems Engineer these days deals with a range of different computer architectures.\n\nEven the simplest computer classifies as a computer system, because at least two components (hardware and software) have to work together. But the real meaning of "computer system" comes with interconnection. Many computer systems can interconnect, that is, join to become a bigger system. In industry these days the interconnection of Variable speed drives and Programmable Logic Controllers (PLC's) to automate production lines and control motors is a common example of a computer system.\n\nInterconnecting different computer systems can prove difficult due to incompatibilities. Sometimes these difficulties occur due to incompatabilities between differing hardware and sometimes between differing software. Technically knowledgeable people can configure disparate computers to communicate using a set of rules and constraints known as protocols. Protocols attempt to precisely define the communication within and between computing endpoints. If two computer systems define the same protocols, they may be capable of interconnecting and become a part of a larger system.\n\nCommon computer system communications protocols include: Asi Profibus Modbus Canbus RS232 RS485\n\nEthernet based communications are also emerging as a computer systems communication protocol\n\nRetrieved from "http://en.wikipedia.org/wiki/Computer_system"

if your looking for names of programs there are hundreds out there.  But the jist of it is anything build for good to lock down a pc and make sure its ok will can do the opposit and help a person hack into a computer.

That would depend on which system you're talking about!\n\nWithout more details, I'd say a "system password" is at the hardware / BIOS level, whereas a software password is at the operation system or application level. However, that's only a guess, as your question is rather vague.

You' need to go to a site about defeating security systems. Defeating security systems may be illegal and dangerous.

It depends on what you mean by completely.\n\nThe completest way - security wise - is to find a program what will write and rewrite and rewrite random chunks of data over stuff.  Simply writing everything with 0101010 does not gurantee and complete erase because data that is stored on the disc (expecially for long amounts of time) leave a magnetic trace that is still present after the 0101010 rewrite.  Since the pattern 0101010 isn't random, it's easy to filter that out to find the contents of the information.

If by security systems, you mean programs that include a virus scanner, you should not use two at the same time.  They will conflict with each other and slow the computer to a crawl.

Hardware are the parts of your computer that you can see and touch. E.g.: CPU, monitor, keyboard, mouse, and any other thing you might use with your computer.\nSoftware is another word for computer programs. Computer programs include both the operating system (such as Windows), and other programs such as Word, Excel, Internet Explorer, Games, etc.

It means you don't break into other people's computers, basically...

What type of scanning?\n  - Anti-Virus\n  - Anti-Spy\n  - Scandisking \n  - Security port scanning?\n\nWhat is the exact message that comes up?\nNot trying to be difficult, just need to know more so we can help you out here.

It's by opposition to hardware.\n\nHardware = all the physical bits of computers (screen, chips, sound cards, keyboard and so on)\n\nSoftware = all the programmes, ie coded instructions

Logical Security consists of software safeguards for an organization’s systems, including user ID and password access, authentication, access rights and authority levels. These measures are to ensure that only authorized users are able to perform actions or access information in a network or a workstation. It is a subset of computer security Elements of logical security include:\n\nUser IDs, also known as logins, user names, logons or accounts, are unique personal identifiers for agents of a computer program or network that is accessible by more than one agent. These identifiers are based on short strings of alphanumeric characters, and are either assigned or chosen by the users.\n\nAuthentication is the process used by a computer program, computer, or network to attempt to confirm the identity of a user. Blind credentials (anonymous users) have no identity, but are allowed to enter the system. The confirmation of identities is essential to the concept of access control, which gives access to the authorized and excludes the unauthorized.\n\nBiometrics authentication is the measuring of a user’s physiological or behavioral features to attempt to confirm his/her identity. Physiological aspects that are used include fingerprints, eye retinas and irises, voice patterns, facial patterns, and hand measurements. Behavioral aspects that are used include signature recognition, gait recognition, speaker recognition and typing pattern recognition. When a user registers with the system which he/she will attempt to access later, one or more of his/her physiological characteristics are obtained and processed by a numerical algorithm. This number is then entered into a database, and the features of the user attempting to match the stored features must match up to a certain error rate.\n\nToken Authentication is comprised of security tokens are small devices that authorized users of computer programs or networks carry to assist in identity confirmation. They can also store cryptographic keys and biometric data. The most popular type of security token (RSA’s SecurID) displays a number which changes every minute. Users are authenticated by entering a personal identification number and the number on the token. The token contains a time of day clock and a unique seed value, and the number displayed is a cryptographic hash of the seed value and the time of day. The computer which is being accessed also contains the same algorithm and is able to match the number by matching the user’s seed and time of day. Clock error is taken into account, and values a few minutes off are sometimes accepted. Another similar type of token (CryptoCard) can produce a value each time a button is pressed. Other security tokens can connect directly to the computer through USB, Smart card or Bluetooth ports, or through special purpose interfaces. Cell phones and PDA's can also be used as security tokens with proper programming.\n\nPassword Authentication uses secret data to control access to a particular resource. Usually, the user attempting to access the network, computer or computer program is queried on whether they know the password or not, and is granted or denied access accordingly. Passwords are either created by the user or assigned, similar to usernames. However, once assigned a password, the user usually is given the option to change the password to something of his/her choice. Depending on the restrictions of the system or network, the user may change his/her password to any alphanumeric sequence. Usually, limitations to password creation include length restrictions, a requirement of a number, uppercase letter or special character, or not being able to use the past four or five changed passwords associated with the username. In addition, the system may force a user to change his/her password after a given amount of time.\n\nTwo-Way Authentication involves both the user and system or network convincing each other that they know the shared password
