Answer:
For 32 bits Instruction Format:
OPCODE DR SR1 SR2 Unused bits
a) Minimum number of bits required to represent the OPCODE = 3 bits
There are 8 opcodes. Patterns required for these opcodes must be unique. For this purpose, take log base 2 of 8 and then ceil the result.
Ceil (log2 (8)) = 3
b) Minimum number of bits For Destination Register(DR) = 4 bits
There are 10 registers. For unique register values take log base 2 of 10 and then ceil the value. 4 bits are required for each register. Hence, DR, SR1 and SR2 all require 12 bits in all.
Ceil (log2 (10)) = 4
c) Maximum number of UNUSED bits in Instruction encoding = 17 bits
Total number of bits used = bits used for registers + bits used for OPCODE
= 12 + 3 = 15
Total number of bits for instruction format = 32
Maximum No. of Unused bits = 32 – 15 = 17 bits
OPCODE DR SR1 SR2 Unused bits
3 bits 4 bits 4 bits 4 bits 17 bits
Answer:
The answer to this question is given below in the explanation section.
Explanation:
You can find a single number or name in a large worksheet containing thousands of numbers and names using the find and replacement feature in excel.
You can use Ctrl+F keyboard shortcut for finding and replacing features. When you press Ctrl+F, a dialog will get open, using this dialog, you can find the required number or name while entering in the search text box. Then, click on the Find button, if the worksheet matches the result, give you the matched result in the yellow highlighted color.
Also, you can use Ctrl+F to replace a name or number with some other name or number.
Alternatively, you can do this using the home tab, then find the option find and select under the editing group of commands.
Answer: Joystick is the only one that makes sense, a stylus and digitizer are both used on drawing tablets, not computer games.
The answer is B) Template.
Various templates are available in most all desktop publishing programs, from resume templates in Word to Income Statement templates in Excel. Templates are useful for skipping the general "setup" process of making a document, and allow you to focus more on filling the document with the relevant data and polishing it to your specific needs once most of the legwork is done.
