Desktop computer locks can be hardware or software. Hardware locks prevent access to certain parts of a computer or prevent the removal of components. Software locks require a password to access certain aspects of a computer. Some hardware locks require a device to be plugged in to turn on or function properly. Software locks can initiate a system lockout without the correct username and password.
There are several types of locks for desktop computers, although they are usually hardware or software locks. Hardware locks are physical locks, usually requiring a key or combination to unlock, used to prevent the removal of computer devices or to restrict access to certain parts of a computer. There are also hardware locks that can be used to prevent a person from accessing a computer unless a device is plugged in. Desktop software locks are programs installed on a computer that lock certain aspects of a computer unless a password is entered.
Desktop computer hardware or physical locks are used to prevent people from removing computer components or to restrict access to certain parts of a computer. Wire cables are often used to secure computer components in place, by passing the cable through rings on the tower, monitor, and other computer components, and then securing it to a desk. A padlock is typically part of this wire, and the lock usually requires a combination or key to release the components.
You can use other desktop computer hardware locks to prevent unauthorized access to certain parts of a computer. A metal plate can be placed over the disk tray on a tower computer and held in place by a padlock to prevent unauthorized users from installing programs or applications from a disk. There are also hardware locks that can be used to limit who can turn on or even use a computer. These desktop computer blocks are usually dongles or other small devices connected to a computer through a Universal Serial Bus (USB) port or similar connection.
Once installed, the device must be present for the computer to turn on or function properly. This allows the computer owner or system administrator to keep the dongle or device with them and prevent others from accessing the system. Some of these desktop computer lockouts are even specific to particular programs, preventing unauthorized users from accessing certain software without the correct authentication device.
Software lockouts for desktop computers typically consist of a program that effectively locks down the system without entering a correct username and password. Many operating systems (OS) have these types of locks as standard features, but there are also programs that can be installed to provide additional protection. Once one of these programs is installed, a computer user can initiate a hang or it can occur when a user is inactive for a certain amount of time. Access to that system is then blocked and disabled without the user entering the correct password.
