    COW stands for?
    COW stands for Copy over write. COW allows both parent and child processes to share the same pages initially.
    Computer Science Fundamentals
    The ________ directive instructs the assembler to begin memory allocation for a segment/block/code from the stated address.
    When an ORG is written, the assembler starts the location counter to keep track of the module’s allotted address as specified in the directive.

    ____________ operate at bottom two layers of the OSI model.
    Bridges operate at the bottom two layers of the OSI model. It connects networks that use the same communication protocols above data-link layer.
    Computer Science Fundamentals
    WANs that need to interconnect a very large number of sites.
    Wide Area Networks that need to interconnect a very large number of sites, or are built using smaller routers that can support only a few serial connections, may find the two-tiered architecture insufficiently scalable.
    Computer Science Fundamentals
    The process of forming a new class from an existing class.
    The answer is inheritance. The base class is the parent class and the new class is called the child class.

    1 yottabyte = ______________
    1 yottabyte is equal to 1024 ZB, which stands for zettabyte. Further, 1 ZB=1024 EB (exabyte) and and 1 EB=1024PB (petabyte).
    Computer Science Fundamentals
    The rate at which the problem size need to be increased to maintain efficiency.
    Isoefficiency is the rate at which the problem size need to be increased to maintain efficiency.
    Computer Science Fundamentals
    They normally interact with the system via user interface provided by the application software.
    Users interact with the system via user interface that is given by the application software. Application software is a set of instructions designed to serve a particular purpose.
