Answer:

If a good friend comes to me for advice in pursuing a music career. With my knowledge of digital technology and the performing

arts, my advice to use digital technology to help build her career by <u>Delivering service to clients .</u>

Explanation:

<u>There were several reasons for this: </u>

• Being able to access work platforms and resources removed the need to travel back

to office bases because remote access allowed the completion of administrative

tasks where the practitioner was working.

• Working with clients in rural and isolated areas can prove difficult in terms of meeting

clients face to face and digital solutions helped to resolve this. This is because more

clients can be seen remotely than when practitioners must travel to see them.

A digital computer has a memory unit with 16 bits per word. The instruction set consists of 72 different operations. All instruc

OLga [1]

Answer:

a. 7 bits b. 9 bits c. 1 kB d. 2¹⁶ - 1

Explanation:

a. How many bits are needed for the opcode?

Since there are 72 different operations, we require the number of bits that would contain 72 different operations. So, 2ⁿ ≥ 72

72 = 64 + 8 = 2⁶ + 8

Since n must be an integer value, the closest value of n that would contain 72 different operations is n = 7. So, 2⁷ = 128

So, we require 7 bits for the opcode.

b. How many bits are left for the address part of the instruction?

bits left = bits per word - opcode bit = 16 - 7 = 9 bits

c. What is the maximum allowable size for memory?

Since there are going to be 2⁹ bits to addresses each word and 16 bits for each word, the maximum allowable size for memory is thus 2⁹ × 16 = 512 × 16 = 8192 bits.

We convert this to bytes

8192 bits × 1 byte/8 bits = 1024 bytes = 1 kB

d. What is the largest unsigned binary number that can be accommodated in one word of memory?

Since the number go from 0 to 2¹⁶, the largest unsigned binary number that can be accommodated in one word of memory is thus

2¹⁶ - 1

Construct a SQL query that displays a list of colleges, their sity/state, the accrediting agency, and whether or not the school

Alex787 [66]

Answer:

SELECT college, city_state, accre_agency, distance LIMIT 10

Explanation:

Given

Table name: College

See attachment for table

Required

Retrieve top 10 college, state, agency and school distance from the table

To retrieve from a table, we make use of the SELECT query

The select statement is then followed by the columns to be selected (separated by comma (,))

So, we have:

SELECT college, city_state, accre_agency, distance

From the question, we are to select only first 10 records.

This is achieved using the LIMIT clause

i.e. LIMIT 10 for first 10

So, the complete query is:

SELECT college, city_state, accre_agency, distance LIMIT 10
