A hard copy refers to a physical, printed version of a document or file. It is a tangible representation of information that can be held and viewed without the need for any electronic device. In contrast, a soft copy refers to a digital version of the same document or file that can only be accessed and viewed using electronic devices such as computers or smartphones. The other options, monitor and hardware, are not directly related to the concept of a hard copy.

A pixel is a tiny dot of light on a screen that represents a single point in an image or display. It is the smallest unit of measurement in digital imaging and is used to create images by combining different colored pixels. Each pixel contributes to the overall image and its color and brightness can be controlled to create different visual effects. Therefore, a pixel is the most appropriate term to describe a tiny dot of light on a screen.

Resting your hands, arms, or wrists while keying is not okay. It is important to maintain a neutral and relaxed position while typing to prevent strain and injury. Resting on the keyboard or desk can lead to unnecessary pressure on the wrists and can cause discomfort or repetitive strain injuries. It is recommended to use proper typing techniques and take regular breaks to avoid fatigue and promote healthy typing habits.

The statement is false because the majority of patients with Carpal Tunnel Syndrome do recover. Carpal Tunnel Syndrome is a common condition that causes numbness, tingling, and weakness in the hand and arm. With proper treatment, such as splinting, medication, physical therapy, or in some cases, surgery, most patients experience significant improvement in their symptoms and are able to regain normal hand function. Therefore, it is incorrect to say that the majority of patients with Carpal Tunnel Syndrome never recover.

A cursor is a blinking line or shape on the screen that indicates the current position for inputting characters. It helps the user identify where the next character will be inserted or where the next action will take place. The cursor can be moved using a mouse or keyboard to navigate through the screen and interact with different elements.

The statement suggests that the recurrence of Carpal Tunnel Syndrome after treatment (surgery) is rare. This means that it is unlikely for the condition to come back after undergoing surgery. This could be because the surgery aims to alleviate the compression of the median nerve in the wrist, which is the main cause of Carpal Tunnel Syndrome. However, it is important to note that individual cases may vary, and there could still be a small possibility of recurrence in some instances.

Wearing splints is a commonly recommended treatment for Carpal Tunnel Syndrome. Splints help to immobilize the wrist and keep it in a neutral position, which reduces pressure on the median nerve and alleviates symptoms. Additionally, splints can also be used as a preventive measure for individuals at risk of developing Carpal Tunnel Syndrome, such as those who perform repetitive hand movements or have certain underlying conditions. By wearing splints, individuals can minimize the strain on their wrists and potentially avoid the onset of Carpal Tunnel Syndrome.

Software refers to the programs and applications that run on a computer. It is a collection of instructions and data that tell the computer how to perform specific tasks.

Therefore, the correct answer is software.

A megabyte is a unit of digital information storage that is approximately equal to one million bytes. It is commonly used to measure the size of files, documents, and data storage capacity. In the given options, "Gigabyte" refers to a unit of storage that is larger than a megabyte, "Bit" refers to the smallest unit of information in computing, and "ROM" stands for Read-Only Memory, which is a type of computer memory that cannot be modified. Therefore, the correct answer in this context is "Megabyte," as it is the unit that is closest in magnitude to "About a million bytes."

Hardware refers to the physical components of a computer that can be touched and interacted with. This includes devices such as the hard drive, which stores data, and hard copy devices like printers. Software, on the other hand, refers to the programs and instructions that run on the hardware. Therefore, the correct answer is hardware as it specifically mentions the parts of the computer that can be physically touched.

The statement is false because yoga has been proven to reduce pain and improve grip strength among people with Carpal Tunnel Syndrome. Numerous studies have shown that practicing yoga can help alleviate the symptoms of Carpal Tunnel Syndrome, including reducing pain and improving grip strength. Yoga poses and stretches can help to release tension in the wrists and hands, improve blood circulation, and strengthen the muscles in the affected area, leading to reduced pain and improved grip strength.

The median nerve supplies feeling to the skin of the thumb, index finger, middle finger, and half of the ring finger. This is because the median nerve is responsible for innervating the muscles and providing sensation to these specific areas of the hand.

The statement is false because there is no evidence to support the claim that women are 5 times more likely to develop Carpal Tunnel Syndrome. Carpal Tunnel Syndrome is a condition that occurs when the median nerve, which runs from the forearm into the hand, becomes compressed at the wrist. It can affect both men and women, although certain factors like repetitive hand movements and hormonal changes during pregnancy may increase the risk. However, there is no data to suggest that women are significantly more likely to develop this condition compared to men.

The symptom of "Fingers feel tired and cold" is not associated with Carpal Tunnel Syndrome. Carpal Tunnel Syndrome typically presents with symptoms such as numbness, tingling, and pain in the hand and fingers, especially the thumb, index, middle, and ring fingers. Other common symptoms include decreased grip strength, difficulty with fine motor tasks, and a sensation of needing to "shake out" the hand or wrist to alleviate discomfort. However, feeling tired and cold in the fingers is not a recognized symptom of Carpal Tunnel Syndrome.
