Computers and Technology
1 answer:
Helga [31]3 years ago
4 0

Answer:

FFF4

Explanation:

Binary representation of 12 = 00001100

Expressing it in hexadecimal format : 0C

Binary representation of -12:

Step 1 : Computing 1's complement for 12 =11110011

Step 2 : Adding 1 to 1's complement to get the 2's complement =>

11110011+1 = 11110100

Converting the 2's complement representation to hexadecimal format:

F4 ( 8 bit representation) or FFF4 ( 16 bit representation)

computer has a 32-bit instruction word broken into fields as follows: opcode, six bits; two register file address fields, five b
lina2011 [118]

Answer:

a.  2^6, or 64 opcodes.

b.  2^5, or 32 registers.

c. 2^16, or 0 to 65536.

d.  -32768 to 32768.

Explanation:

a. Following that the opcode is 6 bits, it is generally known that the maximum number of opcodes should be 2^6, or 64 opcodes.

b. Now, since the size of the register field is 5 bits, we know that 2^5 registers can be accessed, or 32 registers.

c. Unsigned immediate operand applies to the plus/minus sign of the number. Since unsigned numbers are always positive, the range is from 0 to 2^16, or 0 to 65536.

d. Considering that the signed operands can be negative, they need a 16'th bit for the sign and 15 bits for the number. This means there are 2 * (2^15) numbers, or 2^16. However, the numbers range from -32768 to 32768.

A mail merge data source must contain
Katena32 [7]

Answer:

A. a collection of organized data.

Explanation:

It can be a data source, or a database, an excel sheet. or access database. However, it must be well-formatted and hence organized. filtering of data is not necessary, as well as it is not any barrier to the number of the set of data, or the data being sorted. Unsorted data is also fine, and multiple set of data is also fine. It must be known that a data source can be formed from multiple sets of data through the query. And the resultant data source can be used by the mail merge. However, the data source must be a collection of organized data. Hence, A is the correct answer.

How are water resources and air adversely affected by environmental degardation?​
Nonamiya [84]

Answer:

Environmental degradation is one of the ten threats officially cautioned by the High-level Panel on Threats, Challenges and Change of the United Nations. The United Nations International Strategy for Disaster Reduction defines environmental degradation as "the reduction of the capacity of the environment to meet social and ecological objectives, and needs".[4] Environmental degradation comes in many types. When natural habitats are destroyed or natural resources are depleted, the environment is degraded. Efforts to counteract this problem include environmental protection and environmental resources management.

There are many examples of environmental degradation throughout the world. A recent example is the 2019 Amazon rainforest wildfires. The Amazon makes up 60% of all rainforests. It is the earth's lungs and with it getting destroyed is posing a huge threat to the environment and the whole world. The effects of the deforestation will pose major impacts on the world around us. The constant cutting down of trees is getting rid of our oxygen supply as well as the absorption of co2. With the continuation of deforestation we will have less available oxygen in the world which could have detrimental effects on human health. An alternate issue that results from this is the overconsumption and waste of the paper products that come from those trees. The waste it typically produces does not get recycled, therefore, immense amount of waste is created. An additional harmful result from this is the degradation of the soil. The constant deforestation causes the soil to become less nutrient which will make it harder to be used again.
