Computers

Its an output device.

By visual display unit I assume you're referring to one of the following: a tv, a computer monitor or a laptop screen. All 3 are output devices. The difference b/w an input and an output device is simply user input. An input device receives input from a user, an output device does not.

A mouse (receives user clicks), A microphone (receives user audio), a keyboard are input devices.

Phototransistors have several important advantages that separate them from other optical sensors. For example, phototransistors produce a higher current than photodiodes while also being able to produce a voltage, something that photoresistors cannot do. Phototransistors are very fast and are capable of providing nearly instantaneous output. Phototransistors are relatively inexpensive, simple, and small enough to fit several of them onto a single integrated computer chip.

No. A PC Card is a small card slot that is usually found on a notebook. It is really rare that it is on a desktop or tower computer. An express card is a type of a PCI card that fits in a slot in the motherboard.

Computer viruses can cause and do this:

Delete files.

Various messages in files or on programs.

Changes volume label.

Marks clusters as bad in the FAT.

Randomly overwrites sectors on the hard disk.

Replaces the MBR with own code.

Create more than one partition.

Attempts to access the hard disk drive, which can result in error messages such as: Invalid drive specification.

Causes cross-linked files.

Causes a "sector not found" error.

Cause the system to run slow.

Logical partitions created, partitions decrease in size.

A directory may be displayed as garbage.

Directory order may be modified so files, such as COM files, will start at the beginning of the directory.

Cause Hardware problems such as keyboard keys not working, printer issues, modem issues etc.

Disable ports such as LPT or COM ports.

Caused keyboard keys to be remapped.

Alter the system time / date.

Cause system to hang or freeze randomly.

Cause activity on HDD or FDD randomly.

Increase file size.

Increase or decrease memory size.

Randomly change file or memory size.

Extended boot times.

Increase disk access times.

Cause computer to make strange noises, make music, clicking noises or beeps.

Display pictures.

Different types of error messages.

CMOS battery

A person can purchase a notebook computer in several different stores. A person can buy one at Best Buys as well as Office Depot. Notebook computers are also found at the dell website and at the overstock site.

The sequence Control-Alt-Delete, used to reboot a computer under distress, was created for the IBM PC by David Bradley.

Historically speaking, any computer that is connected to a public network and running a Microsoft Windows operating system is more vulnerable to attack than any other operating system. Particularly, out of date, and unpatched versions of windows are worse off than otherwise. This is due to several factors - Windows Operating Systems usually have more security vulnerabilities than other operating systems do, but mostly they are more vulnerable because of the popularity of windows. There are many more people using Windows than other Operating Systems, so there is more incentive for hackers to target it.

Medicine:

Doctors use infrared lamps to treat skin diseases and relieve the pain of sore muscles. In these treatments, the infrared rays pass through the patient's skin and produce heat.

Science:

Scientific advances pertaining to infrared have allowed buildings to keep cool even in the summer. Gold transparent films in the windows of large office buildings reflect infrared and help to keep temperatures cool.

Consumer Goods:

Photographers use film that is sensitive to infrared rays to take pictures in places where there is no visible light. Burglar alarms also use infrared.

Industry

Infrared is used extensively in specially-designed ovens for drying painted and enameled surfaces, leather, metals, papers and textiles.

it is good because you don't have to go through all the other websites like the one you are looking for. And you can quickly get access to the site you want by bookmarking it or adding it to favourites.

This question is non-sense, but if the computer is unplugged, it can not acquire a virus.

I think it's meant to say, "If your computer is unplugged and then plugged back in, will there be any viruses waiting to infect the computer?"

That's what I think.

The PS-4's input/output connections include...Wi-Fi, Ethernet, Bluetooth and USB 3 ports... Providing your notebook can communicate via one or more of those methods - you should be able to get the computer & PS-4 to 'talk' to each other.

The Pentium MMX uses a core voltage of 2.8 volts and I/0 votage of 3.3 volts. For this proccesor one votage is used for external operations and another for internal operations.

WinZip extracts files compressed in .zip or .rar format.

A monitor is an output device.

A touchscreen monitor is different.

The touch panel, which is installed over the monitor is an input device, but the monitor itself is strictly an output device.

if buying for home the following are the best options

speakers:-5.1

graphics:-ati radeon

monitor:= samsung led 19 inch

keyboard &mouse :-logitech

motherboard:- biostar

Logical link control manages traffic in the Open Systems Interconnection and identifies line protocols including NetBIOS or NetWare. Medium Access Control is responsible for sharing physical connection to the network amongst numerous computers via Ethernet.

Have you ever studied analog computers? Didn't think so.

The first system I worked on in 1978 was a military avionics unit containing 6 digital and 2 high speed hybrid (digital & analog) computers in a 6 inch square by 2 foot long box. Analog drifts and can rarely give more than 2 digit precision answers.
