While a barcode only holds information in the horizontal direction, a QR code does hold information in both horizontal and vertical directions. Due to this, a QR code holds hundreds of times more information than a barcode.
With that being said they have different purposes, and there about the same developed as each other, unless you count how much information they can store.
SRAM [STATIC] is a type of memory, it is five times faster than DRAM [which is found in most computers] and it depends on the use of electricity. It is designed in such a way that its constant refreshing is not require, it is much more expensive than the DRAM and it is therefore only used in cache memory application.<span />
Answer:
c. Wait about 30 minutes for the system to cool down and try again
Explanation:
When troubleshooting it is important to eliminate all possible faults one at a time. In this scenario, the first problem could be an overheating CPU. To eliminate overheating the first step would be to let the system cool down for some time then restart the computer. If the computer turns on and then hangs again after 15 minutes, the next step would be to install an additional fan and then monitor its performance. If the problem is eliminated, it means there was a problem with the cooling system of the computer. However, if the problem persists, it could be a problem with the power supply which might need replacing.
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
