What is the difference between a Zip disk and a Floppy disk?

A Zip disk and a floppy disk are both types of removable storage media, but they have several key differences. Zip disks have a higher storage capacity than floppy disks, typically ranging from 100MB to 750MB compared to the 1.44MB capacity of a floppy disk. Zip disks also use a different type of magnetic storage technology, which allows for faster data transfer speeds and more reliable data storage. Additionally, Zip disks are physically larger in size compared to floppy disks, which were more commonly used in the past for smaller data storage needs.

What is laser scan display in computer graphics?

Oh, dude, laser scan display in computer graphics is like this fancy technology where a laser beam is used to draw images on a screen by scanning back and forth really fast. It's like a high-tech version of those old-school Etch A Sketch toys, but way cooler. So, yeah, it's basically a laser drawing stuff on your screen at lightning speed.

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:

  1. Preparation: This stage involves identifying the updates needed, checking system requirements, and ensuring data backups are in place.

  2. Download: Updates are then downloaded from the appropriate sources, such as the software vendor's website or through an automated update service.

  3. Installation: The downloaded updates are then installed on the computer, following specific instructions provided by the software vendor.

  4. 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?

Numeric characters are used to represent numbers, typically in a mathematical context, and include digits 0-9. Alphabetic characters, on the other hand, represent letters of the alphabet, typically used in language and communication. In computing, numeric characters are typically used for mathematical operations, while alphabetic characters are used for text input and manipulation.

The part of the computer that does the calculations?

The part of the computer that performs calculations is the Central Processing Unit (CPU). The CPU is often referred to as the "brain" of the computer because it carries out instructions from programs, processes data, and performs arithmetic and logical operations. Specifically, the Arithmetic Logic Unit (ALU), a component within the CPU, is responsible for carrying out the actual calculations and logical decisions.

What part of the colossus computer enabled it to do the processing?

The vacuum tubes (valves) in the Colossus computer enabled it to perform processing. These tubes acted as electronic switches, allowing Colossus to execute complex calculations and process data at high speeds. The extensive use of vacuum tubes made Colossus one of the first programmable electronic digital computers, capable of breaking encrypted messages during World War II.

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?

Active Preventive Maintenance involves scheduled, proactive tasks to maintain and optimize a computer system, such as software updates, hardware replacements, or cleaning components to prevent failures.

Passive Preventive Maintenance focuses on environmental factors, like ensuring proper ventilation, stable power supply, and safe handling of hardware, to reduce the risk of system damage.

Key Difference:

Active maintenance directly involves action on the system, while passive maintenance addresses external factors to preserve its condition.

What 8 letter word links column computer and stereo?

The 8-letter word that links "column," "computer," and "stereo" is "speaker." In the context of a column, a speaker can refer to a person giving a speech or a device that produces sound. In the context of a computer, a speaker can refer to a component that emits audio output. In the context of a stereo system, a speaker is an essential component that reproduces sound.

What are 10 examples of processing devices?

10 hardware devices include these listed here:

  • RAM
  • hard disk
  • keyboard
  • prosessor chip
  • motherboard
  • graphic card
  • USB
  • CD drive
  • floppy drive
  • webcam

How do you get into the C drive in DOS?

To access the C drive in DOS, you would first need to open the Command Prompt by typing "cmd" in the Windows search bar and pressing Enter. Once the Command Prompt window opens, you can type "C:" and press Enter to switch to the C drive. You can then navigate through directories using commands like "dir" to list files and "cd [directory name]" to change directories.

Why is the globe round?

Oh, dude, the globe is round because of gravity and stuff. Like, the Earth's mass pulls everything towards the center, making it all squishy and round. So, yeah, that's why we don't fall off the edge when we reach the end of the map.

How is 3d animation different form ordinary animation?

3D animation is different from traditional or 2D animation in that it involves creating characters and environments in a three-dimensional space, allowing for more depth, realism, and dynamic movements. While traditional animation relies on hand-drawn frames or 2D computer-generated images, 3D animation uses specialized software to model, rig, and animate objects or characters in a 3D space, creating lifelike motion and depth.

This added dimension allows for more flexibility in visual effects, lighting, and camera angles, resulting in a more immersive experience. Brands like Cloud Animations specialize in creating 3D animations that offer detailed visuals and intricate designs, setting them apart from more basic, flat 2D animation styles.

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.

Not an application software?

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?

Well, honey, a light pen is as old-school as a rotary phone. It's basically a fancy stick that can detect light and send signals to a computer when you point it at the screen. Think of it like a high-tech pointer for selecting stuff on your computer screen. But let's be real, you're better off using a mouse or your finger these days.

What are the inputs and output of the oven?

Well the output of any oven should be Heat (thermal energy), with exhaust fumes and gases as (unwanted) secondary outputs occurring in most designs.

And the input can be any sort of fuel to produce said heat, depending on the oven. Most commonly, the input of an oven is electricity, gas, oil or wood.
