Is a photocopy machine an output device?
A photocopy machine is not considered an output device. It is actually a combination of both input and output devices. The input part involves placing the document to be copied on the glass, while the output part involves producing a duplicate copy of the document on a separate piece of paper. Therefore, a photocopy machine is more accurately described as an input-output device rather than solely an output device.
Differentiate computing from computer?
Computing refers to the process of using computer technology to complete tasks, solve problems, or perform operations. It encompasses a wide range of activities such as data processing, algorithmic calculations, and software development. On the other hand, a computer is a physical device that is capable of receiving, processing, and outputting data according to instructions provided by software programs. In essence, computing is the broader concept that involves utilizing computers as tools to facilitate various computational activities.
What computer is best for a dj?
Many laptops have the ability to satisfy DJs. Amongst the many laptops I've DJed with, I'd have to say the Apple Macbook Pro is by far the best due to the simplistic ways of the operating system.
What is the difference between a Zip disk and a Floppy disk?
Yes, Zip discs are considerably larger than standard floppy disks.
A standard floppy disc is 90mm × 94mm x 3mm. Zip discs are much wider longer and thicker at 97mm x 98.5mm x 6mm. This is because internally the platter of a Zip disk had a much higher spin speed and required space to spin free of any resistance.
What is laser scan display in computer graphics?
It is well known that conventional displays using phosphors or a lamp as a light source can express only about 30 % of all visible colors. Recently various efforts to expand color gamut of displays are being tried. The most efficient one is the laser display which is realized with lasers as the light source. Since lasers have the most saturated colors, the laser display has wider color gamut than that of the conventional displays using phosphors or a lamp. Its color gamut is almost three times wider than that of the conventional displays [1, 2]. So the trials to use lasers aslight sources have been continued. Figure 1 and Figure 2 show the comparison of color gamut between the conventional displays (sRGB) and laser display. With three lasers of RGB colors, up to 83 % of human visible color area can be expressed while color gamut is only 36 % in the conventional displays.
What is a four stage programme for downloading and installing updates and patches on computers?
A four-stage program for downloading and installing updates and patches on computers typically involves the following steps:
-
Preparation: This stage involves identifying the updates needed, checking system requirements, and ensuring data backups are in place.
-
Download: Updates are then downloaded from the appropriate sources, such as the software vendor's website or through an automated update service.
-
Installation: The downloaded updates are then installed on the computer, following specific instructions provided by the software vendor.
-
Verification: Finally, the system is verified to ensure that the updates have been successfully installed and are functioning correctly, often through system checks or test runs.
The difference between numeric and alphabetic?
alphabets contains only the letters from a-z while alphanumeric has both numbers and letters...
example...
ABCDEFGHIJ are alphabets
A4F54F54F5G AND 3F3FS34TH3 are both alphanumeric...
alphanumeric are commonly used as passwords since they are more difficult to crack that words or numbers separately...
The part of the computer that does the calculations?
Processor. It is sometimes called "Central Processing Unit" or CPU.
What part of the colossus computer enabled it to do the processing?
The Colossus computer worked using one to two thousand thermionic valves.
What were the two main problems caused by using the valves in colossus computer?
Reliability and heat were the main problems. Valves were fragile devices that, due to the relatively primitive way they were manufactured, failed pretty quickly. In addition to that, they gave off vast amounts of heat. This meant they needed expensive air-conditioning systems to keep their temperature down.
Define the difference between active and passive Prevetive Maintenance In Computer System?
Well, darling, active preventive maintenance involves regularly scheduled tasks to keep your computer system running smoothly, like software updates and virus scans. Passive preventive maintenance, on the other hand, is more about setting up systems to prevent issues from happening in the first place, like installing surge protectors or proper ventilation. Basically, one is like doing regular check-ups, while the other is like putting up safeguards to avoid disasters.
How do you get into the C drive in DOS?
If you are in DOS, just type C: and hit enter.
It depends on what operating system you are using, but if it's windows XP or windows 2000 do this process:
Start menu --> Run --> Type in "cmd" and press enter -->
If you are using an older version of windows then type "command" in place of "cmd" .
From there it takes a bit of knowledge of the dos system. If you type "help" there is a list of commands you can use. Here are a few basic commands to help you:
If you type in "chdir c:" (stands for change directory) that will bring you to the root of your C drive. From there if you type "dir" (stands for directory) it will list any subfolders and files in which ever directory you are in. To continue into another folder, type "chdir foldername".
If you are deep into the system and wish to only go back a folder at a time, type in "chdir .." instead of the entire address again.
I recommend not deleting any files that you are unfamiliar of because they could be important system files.
The earth (and other planets) are spherical because the force of gravity organized them and they took this form as a preference. When very large masses of material accrete to form something the size of a planet, gravity increases and increases as the material comes together. The mass begins to "pack itself tighter" through the process, and as the arrangement increases in size, the "most effective shape" for the forces acting on the material will dictate that the material form a sphere.
Planets formed in this way have their constituient material heated up by mechanical energy imparted to the material as it accretes. The amount of energy added to the "mix" is almost always sufficient to cause the whole "ball" to become molten. That results in a really, really big ball of liquid rock. And liquid rock is plastic - it can be shaped easily. Gravity does this, and the optimum shape for the conditions - a sphere - will be the result.
Note that the planets usually form in such a way that they are spinning on an axis. The plastic nature of the large mass of the planet and the rotation of the mass couple to "deform" the body a little bit. This gives most planets (earth included) a little bit of a "bulge" at the equator, or, said another way, planets often exhibit a slight flattening at the poles.
How is 3d animation different form ordinary animation?
What you are describing as 'ordinary' is probably 2D, or cartoon animations; i.e. drawings of characters or objects. A 3D animation, on the other hand, involves clay models, or 3D drawings of characters and objects which are then incorporated into an animation.
Can computer make a mistake if yes why if no why?
For the most part, computers do not make mistakes. They generally output answers based on the input given. If the input is wrong, the output can be wrong. In tech terms, we call this "GIGO" -- Garbage in, garbage out.
FWIW, Intel once made a CPU chip that had a floating point math error. For most calculations, it would have meant no errors. However, for very complex programs, the computer would definitely make a mistake with that particular processor on board.
What is the registration code for FIFA 09 PC game?
Oh honey, I can't help you with that. Sharing registration codes is like sharing your toothbrush - it's just not cool. You'll need to purchase the game legally to get your hands on that precious code. Happy gaming, but play by the rules, darling!
Why does Scratch need Adobe Air?
well most of the time adobe air is installed when you install other adobe products. from what ive heard, it's not really bad to uninstall it. some users have experienced not so good performance after uninstalling adobe air but uninstalled acrobat and had no problems. I'm guessing air is needed for adobe to run at it's best. so no, don't really need it but if you like things running at 100% i would keep it. i keep mines and it's only using like 35mb anyway so it's no big deal.
An application software is a type of software designed to perform specific tasks for the user, such as word processing or web browsing. In contrast, a non-application software, also known as system software, is designed to operate and control the computer hardware. Examples of system software include operating systems like Windows or macOS, device drivers, and utility programs that help manage the computer's resources.
What are functions of light pen in computer?
A light pen is a peripheral input device, used for inputting analog information in a digital format.
The "analog" information may be a plan or drawing which needs to be digitized so that it can be manipulated in a computer program.
An architect for example may use a pen to copy a set of drawing into he computer so that they can be manipulated in a CAD program.
