Which of these is not a peripheral in computer terms?
There are many different types of devices that can be considered as peripherals in computer terms. These can include things like keyboards, mice, and printers. However, not all of these devices are peripherals in the true sense of the word. Some of them, like the keyboard and the mouse, are essential components of a computer system. Others, like printers, are not essential but can be very useful in certain situations.
So, which of these is not a peripheral in computer terms? The answer may surprise you. It is the printer. While it is true that a printer can be a very useful peripheral, it is not essential to the functioning of a computer. A computer can function perfectly without ever printing a single page.
There are many reasons why you might want to use a printer. Perhaps you need to print out a document for work or school. Maybe you want to print a photo to hang on your wall. Whatever the reason, a printer can be a great addition to a computer, but it is not essential.

What is a CPU?
A CPU, or Central Processing Unit, is the hardware within a computer that carries out the instructions of a computer program. It performs the basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions.
The term has been in use in the computer industry at least since the early 1960s. CPU is sometimes referred to as the brain of a computer. This analogy dates from the early days of computing, when CPU operations were performed by vacuum tubes anddelay lines
CPUs are manufactured in large volumes by highly automated processes resulting in high unit cost. CPUs are typically small and integrated onto a single circuit board, called a microprocessor.
A control unit (CU) is a component of a CPU that directs the sequence of operations that must be performed to carry out a program. The control unit does not execute these operations; it merely directs which operations are to be executed and in what order. The term "control unit" is sometimes used interchangeably with "CPU".
An arithmetic logic unit (ALU) is a component of a CPU that performs arithmetic and logical operations. The ALU is a digital circuit that takes two input values, called operands, and produces a single output value. The output value is computed based on a set of rules called an algorithm.
The most common type of ALU is a portable, subroutine-based design that includes a small amount of memory. This type of ALU is often called a logic chip. Other ALU designs include dedicated hardware for specific algorithms, such as floating point arithmetic or multiplication.
Floating point arithmetic is a numerical computation method that represents real numbers in a way that can be scaled to a wider range of values. Multiplication is a mathematical operation that produces a product of two numbers.
Input/output (I/O) is the movement of data into and out of a CPU. I/O operations are performed by special purpose circuits called peripherals. Peripherals are devices that are connected to a CPU but are not part of the CPU itself.
The most common type of I/O peripheral is a storage device, such as a hard disk drive or solid state drive. Storage devices are used to store data that is not currently being used by the CPU. Other common I/O peripherals include keyboard and mouse devices, network adapters, and printers.

What is a hard drive?
A hard drive is a data storage device that stores and retrieves digital information using one or more rotating disks (also called platters). The hard drive is the main data storage device in most computers. A hard drive works by storing digital information on a magnetic surface. The platters in a hard drive spin at high speeds and the read/write head accesses the data while the platters are spinning. The read/write head is mounted on a moving arm that accesses the data as the platters spin. The hard drive is a very important part of a computer as it stores all of the data and information. A hard drive can store a large amount of data, and it is usually the primary storage device in a computer. Hard drives are available in a variety of sizes, and they can be internal or external. Internal hard drives are usually connected to the motherboard of a computer using a data cable. External hard drives are usually connected to a computer using a USB or Firewire cable. Hard drives can be used to store any type of data, including text files, image files, video files, and audio files.

What is a monitor?
When you think of a monitor, you might think of the display device that sits on your desk and shows you everything from your document files to your Facebook newsfeed. But the term "monitor" can refer to a lot of different things in the computer world. Here's a look at a few different types of monitors and what they do.
The most common type of monitor is the video monitor, which is the display device that you use to see everything on your computer screen. Video monitors come in a variety of sizes, from small screens that fit in the palm of your hand to large screens that are big enough to give you a cinema-like experience.
While all video monitors display images, some are better suited for certain tasks than others. For example, gamers often prefer monitors with a high refresh rate, which means that the images on the screen are refreshed more frequently and appear more smoothly. Meanwhile, graphic designers often prefer monitors with a high resolution, which means that the images on the screen are more detailed.
Another type of monitor is the CPU monitor, which is a hardware device that monitors the activities of the central processing unit (CPU) in your computer. CPU monitors can be used to track the performance of your computer and diagnose any problems that might be causing it to run slowly.
Finally, there are also software programs that act as monitors. These programs, which are often known as system monitors or process monitors, can be used to track the activities of all the software programs running on your computer. System monitors can be used to help you find and fix problems, or simply to keep an eye on what your computer is doing.

What is a keyboard?
A keyboard is a device used to input text, numbers, and other symbols into a computer or other devices. There are a variety of keyboard types, each with their own benefits and drawbacks. The most common type of keyboard is the Qwerty keyboard, which is named after the six letters that are used most often in English. The Qwerty keyboard has been around for more than a hundred years and is the standard keyboard for most computer users. However, there are other types of keyboards that are designed for specific purposes. For example, the Dvorak keyboard is designed for increased efficiency and ergonomics.
The keyboard is an essential part of the computer, as it is the main way that users input information. The first computers did not have keyboards, and users had to input information using punch cards or other physical means. The first keyboard was invented in the early 1800s by Christopher Latham Sholes, and it was called the type-writer. The type-writer was a major improvement over punch cards, as it allowed users to input information much faster. In 1873, Sholes sold the patent for the type-writer to Remington, and the first mass-produced keyboard was born.
The keyboard has come a long way since then, and there have been many different designs and innovations. Today, there are keyboards designed for a variety of purposes, from gaming to office work. Gaming keyboards often have special features such as backlighting and programmable macro keys. Office keyboards are designed for maximum comfort and efficiency. Some keyboards even have ergonomic features such as wrist rests and split keys.
No matter what type of keyboard you use, it is important to practice proper typing technique. This includes sitting up straight, keeping your wrists level, and using all of your fingers. Proper typing technique will help you avoid pain and injury, and will help you type faster and more accurately.
Keyboards are an essential part of the computing experience, and there is a wide variety of keyboard types to choose from. Whether you use a Qwerty keyboard, a Dvorak keyboard, or a gaming keyboard, it is important to practice proper typing technique. With a little practice, you will be able to type faster and more accurately, and you will be able to avoid pain and injury.

What is a mouse?
A mouse is a small mammal of the order Rodentia. The best known mouse species is the common house mouse. It is also a popular pet. Mice are very social creatures and live in groups. They are omnivorous, meaning that they eat both plants and animals.
Mice have been domesticated for centuries and are used in research laboratories all over the world. They are very intelligent animals and can learn to do simple tasks.
Mice are born blind and deaf. Their eyes open at about two weeks old and they are fully grown at about six weeks old.
Mice are attracted to food that is high in sugar and fat. This is why they are often found in kitchens, where they can find food scraps.
Mice are known to spread diseases, such as salmonella and hantavirus. They can also be a nuisance, chewing on electrical wires and furniture.

What is a scanner?
A scanner is a machine that captures images from photographic prints, slide film, or from the surface of objects, as well as documents. It uses a light-sensitive receptor to create digital images. scanners come in many different sizes and shapes, from desktop scanners that fit on top of a computer to large format scanners that are designed for scanning architectural drawings and other large documents. scanner technology has come a long way since its early beginnings in the 19th century and today there are many different types of scanners available on the market.
The first scanners were developed in the early 1800s by Dr. Alexander Gordon and William Henry Fox Talbot. These early machines used a light-sensitive receptor to capture images. The images were then transferred to a glass plate and viewed under a microscope. In 1851, English photographer Frederick Scott Archer developed the wet plate collodion process, which allowed for the creation of negative images on glass plates. This process became the standard for photography for the next several decades.
In the late1800s, George Eastman developed the Kodak camera, which used a roll of film instead of glass plates. This made photography more accessible to the masses and ushered in the era of snapshot photography. In 1888, Eastman introduced the first hand-held camera, which made photography even more portable.
The first scanners were large and bulky, and could only be used by professional photographers. However, as technology progressed, scanners became smaller and more affordable, making them available for use by the general public. In the early 1990s,flatbed scanners were introduced. These scanners use a light-sensitive receptor to scan images from photographic prints and documents.
Flatbed scanners are the most common type of scanner in use today. They are available in a variety of sizes, from small desktop scanners to large format scanners. Flatbed scanners typically have a higher resolution than other types of scanners, making them ideal for scanning photographs and other graphics-heavy documents.
Today, scanners are an essential part of many businesses and homes. They are used to scan documents, photos, and other images for a variety of purposes, such as storage, sharing, and printing.
