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
File allocation using I nodes. This method is used to decrease the size of the table in the above method. Every file will have an I-node list. Allow a file have 15 pointers a

Explain thread in details
What are the different thread levels? There are two broad type of thread implementation: User-Level Threads -- Thread Libraries. Kernel-level Threads -- System Calls.
The optimal replacement policy, called OPT, is to evict the page which will be accessed farthest into the future. Since we can't predict the future precisely, we can't implement OP
