Example In following Figure a node with physical address 10 sends a frame to a node with physical address 87. The two nodes are connected by a link. At the data link level this frame contains physical addresses in the header. These are the only addresses needed. The rest of the header contains other information needed at this level. The trailer usually contains extra bits needed for error detection 10 Trailer 28 T2 Data 53 65 87 10 87 Source Destination address address

What output does the following multiplexer output? Note: if a line is cut and a number is written, it shows how many bits or how many lines are there. The lines below are 4 bits.

BCD TO 7- Segment decoder i/p for number (4): A.0100 B.0111 C.1001

2) Answer the following sentence with (True) or (False) and correct the false answer: 1. CMPS is used with REPE, REPZ, REPNE and REPNZ. 2. Loop instruction is equal to JNZ instruction 3. SAL and SHL have the same operation. 4. The instruction MOV BX,'B' is allowed. 5. Segment override prefix means we can use any segment register to have the physical address. 6. In CBW, the MSB of AX is copied to all the bits in DX. 7. The following piece of code is used to: Complement PF and CF LAHF AND AH, FOH XOR AH, OFH SAHF 8. In conditional jump, the next instruction is executed if the condition is not met. 9. Assume BL=11H, AX =FFB6 H , the result of executing IDIV BL is AX=FAFD H 10. The instruction queue in the BIU works on LIFO basis.

Implement a full-adder circuit with a decoder and two OR gates. C-- - the f.

Show the starting and ending address of each segment located by the following segment register values. 1. 56F8H 2. C802H 3. 7FFEH 4. 7103H 5. 1110

Question 1 [Svalan i (a) Determine the largest number for Octal number that can be expressed with 4-bit. Convert the number to a Binary number and Gray code. Table 1 shows five (5) set of numbers that represented in BCD number. Convert the numbers into Decimal number and by using Appendix 1, decode the numbers into ASCII coded message. (b) Table 1 Set A 10011000 Set B 01010001 Set C 00110110 Set D 10000100 Set E 00100111 Determine the simplified Sum-of-Product (SOP) expression for the given expression by using Karnaugh map. (c) Р(4, В,С, D) - яМ(3,7,12,13,14,15) D(5,6,11)

A large multiplexer 512 to 1 require how many address line?

To select the ROM the address lines A10-A9 should be: A. 00 B. 01 C. 10 D.10
