Computer Monitors

 

Computer Monitors

There are several types of computer monitors available, each with its own advantages and disadvantages. The main types include CRT, LCD, LED, OLED, and specialized monitors like curved, touch, and gaming monitors. 

Here's a breakdown of the different monitor types:

1. CRT (Cathode Ray Tube) Monitors:

·         These are the older, bulkier monitors that use a cathode ray tube to project images. 

·         They are less common now due to their size and energy consumption. 

 

 

 

 

2. LCD (Liquid Crystal Display) Monitors:

·         LCD monitors are the most widely used type, known for their relatively thin profile and lower power consumption compared to CRTs. 

·         They use liquid crystals to block or transmit light, creating images. 

3. LED (Light Emitting Diode) Monitors:

·         LED monitors are a type of LCD monitor that uses LEDs for backlighting. 

·         They generally offer better brightness, contrast, and energy efficiency compared to traditional LCDs with fluorescent backlights. 

4. OLED (Organic Light Emitting Diode) Monitors:

·         OLED monitors are a newer technology where each pixel emits its own light, eliminating the need for a backlight. 

·         They can offer superior image quality with deep blacks and vibrant colors, but they are typically more expensive. 

5. Specialized Monitors:

·         Curved Monitors:

These monitors have a curved screen, providing a more immersive viewing experience, especially for gaming or watching movies. 

·         Touchscreen Monitors:

These monitors allow users to interact with the computer by touching the screen. 

·         Gaming Monitors:

These monitors are designed with features like high refresh rates, low response times, and adaptive sync technologies to enhance gaming performance. 

Other monitor technologies and panel types:

·         IPS (In-Plane Switching): A type of LCD panel known for its wide viewing angles and accurate color reproduction. 

·         VA (Vertical Alignment): Another type of LCD panel that offers good contrast and color accuracy. 

·         TN (Twisted Nematic): An older type of LCD panel known for its fast response times but with narrower viewing angles and less accurate colors. 

When choosing a monitor, consider factors like screen size, resolution, refresh

CACHE MEMORY

 Cache is very small amount of extremely fast memory inside the microprocessor or on the motherboard It is faster and more expensive than RAM. It Stores information most frequently used by computer. purpose of Cache is to increase processing capabilities of a system and enhance its speed. There are three levels of cache L1 L2 and L3 .L1 is placed inside microprocessor whereas L2 and L3 are on motherboard

Optical Technology

 OPTICAL MEMORY  Optical memory is an electronic storage medium that uses a laser beam to store and retrieve digital data .  It was first used to represent analog sound signals into digital form .  In optical storage technology, a laser beam encodes digital data on an optical disc or laser disc in the form of tiny pits arranged in a spiral pattern on the surface of the disc .  Optical memory was developed by Philips and Sony and released in 1982 in the fourth generation of computers . In optical media such as CDs, DVDs, and Blu-Ray discs,  pits  and  lands  play a crucial role in representing binary information.  Pits are microscopic depressions on the disc’s surface. When a laser beam hits a pit, it shatters, and no reflection is received. As a result, a  binary 0 (O)  is registered. Essentially, pits correspond to the absence of data. Think of pits as the valleys or low points on the disc.: Lands are the flat areas betwe...

Computational Thinking Properties

  Computational Thinking (CT) involves a set of problem-solving skills and techniques that software engineers use to write programs that underlie the computer applications you use such as search, email, and maps.  There are many different techniques today that software engineers use for CT such as: Decomposition: Breaking a task or problem into steps or parts. Pattern Recognition: Make predictions and models to test. Patten Generalization and Abstraction: Discover the law, or principles that cause these patterns. Algorithm Design: Develop the instructions to solve similar problems and repeat the process. DECOMPOSITION Part of being a computer scientist is breaking down a big problem into the smaller problems that make it up. If you can break down a big problem into smaller problems, then you can give them to a computer to solve. For example, if I gave you a cake and asked you to back me another one, you might struggle. But if you watched me making the cake and worked out the i...
