For the first assignment you are required to construct a logic circuit onto a copper clad circuit board (vero board). This construction will require the use of planning the position of the components to use the copper clad connectors, hence minimise external wires and soldering the components in. A word of warning 'it is easier to move a planned drawing compared to de-soldering a component'. This process is easy if we follow simple logical steps
Find the package (components) details of the actual devices used from the circuit diagram i.e.
The circuit uses 3 different type of logic chips a 7408 (quad 2 input AND gate), a 7404 (hex inverter) and a 7486 (quad exclusive or gate). These come in the 14 pin DIL (Dual in line) packages as shown below
Note that the parameter for scanf doesn't need the address operators & because name is an address. However the variable name has no defined space. This can cause problems within C
What is sector sparing? Low-level formatting also sets aside extra sectors not visible to the operating system. The controller can be told to change each bad sector logically w
Load Sharing : Processes are not given to a particular processor. A global queue of threads is used to maintain. Each processor, when idle, picks a thread from this queue. Note th
In modern operating systems, applications do not directly access the physical memory. Instead, they use so-called virtual memory, where each virtual address is translated to a phys
Define a layer that is not of an IO management module MCS that is Management Control System is not of an IO management module
Explain bounded buffer and unbounded buffer. Here in a producer-consumer problem the producer process produces information that is consumed by a consumer process. At this time
Let us consider the pining details of the 68HC11 as shown below. Each pin has a defined function, some easy, some complex. A microprocessor designer should understan
What are the various process scheduling concepts? a) Scheduling queues with diagram b) Queuing diagram c) Schedulers d) Context switch with diagram
List ways to share files among directories in operating systems. a. Copy file from one account into another. b. Link directory entry of "copied" file to directory entry of o
Contiguous allocation: Every file will be allocated contiguous space in the memory. Allow the block size be 1K If a 50K files desires to be allocated space after t
