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

Types of Network,OSI Model

                   Types of Network Ø   A LAN is a network that connects computers within a limited area like a home, school, or office. Ø   It typically uses Ethernet or Wi-Fi for connectivity. Ø   LANs allow sharing of resources such as files, printers, and internet connections. Ø   It is usually high-speed and provides a secure connection within the localized area. Ø   A WAN spans a large geographic area, often connecting multiple LANs. Ø   The internet is the largest example of a WAN. Ø   WANs use long-distance communication links like satellite, leased lines, or public networks. Ø   They are slower than LANs and often involve higher costs due to the distance and technology used.   Ø   A MAN covers a larger area than a LAN but is smaller than a WAN, usually a city or a campus. Ø   It is often used by organization...

  Unit 01 Overview of Computer System Computer System A computer system is a combination of hardware and software components that work together to perform tasks. It includes the physical parts of a computer (hardware) and the programs and instructions that tell it what to do (software). Key components of a computer system: ·        Hardware: This refers to the physical components of a computer, such as the central processing unit (CPU), memory (RAM and storage), input/output devices (keyboard, mouse, monitor), and other physical components.  ·        Software: This encompasses the programs and instructions that tell the hardware what to do. Examples include operating systems (like Windows or macOS), applications (like word processors or web browsers), and other software.  ·        User: The user is the person who interacts with the computer system to ...

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...
