Answer:
Innovation:
Explanation:
Technology is defined as human innovation in action that involves the generation of knowledge and processes to develop systems that solve problems and extend human capabilities.
To innovate is to make changes in something established, especially by introducing new methods, ideas, or products.
The answer is (C) broadband cellular networks
Over the past decade, a majority of the mobile service providers have built 3G networks that use packet-switching technologies. Over time, 3G evolved into HSPDA which is five times faster than 3G. Predictably, 4G networks are now commonplace and are built from LTE and Mobile WiMAX.
Explanation:
A.)
we have two machines M1 and M2
cpi stands for clocks per instruction.
to get cpi for machine 1:
= we multiply frequencies with their corresponding M1 cycles and add everything up
50/100 x 1 = 0.5
20/100 x 2 = 0.4
30/100 x 3 = 0.9
CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8
We find CPI for machine 2
we use the same formula we used for 1 above
50/100 x 2 = 1
20/100 x 3 = 0.6
30/100 x 4 = 1.2
CPI for m2 = 1 + 0.6 + 1.2 = 2.8
B.)
CPU execution time for m1 and m2
this is calculated by using the formula;
I * CPI/clock cycle time
execution time for A:
= I * 1.8/60X10⁶
= I x 30 nsec
execution time b:
I x 2.8/80x10⁶
= I x 35 nsec
Answer:
servers to be upgraded are : APPLICATION AND LOAD BALANCING SERVERS
servers still appropriate to use : DNS AND DHCP SERVERS
Explanation:
The recommendations to be made in line with what the new director of information is asking for includes :
1 ) For the servers to be upgraded : The servers that requires upgrades includes the APPLICATION SERVER and LOAD BALANCING SERVER. this is because these two servers are critical to the growth/expansion of any business, and they handle large volume of data
Recommendations on the servers upgrade includes:
Hardware : 2.3 GHz Intel Xeon Gold 5118 12-Core
CPU chip set : Socket: FCLGA3647, Type: NSBM
Speed : processor 3.2 GHz
caching: > 100 Gb
2) For servers that do not necessarily need to be upgraded : The servers that do not need immediate upgrade are DNS and DHCP
Answer:
False.
Explanation:
Its a DC current which charges any equipment which functions on a energy storage device such as battery. As a battery is a storage device and we know that AC power can't be stored, so chargers are provided with the special type of circuit which converts this AC current into DC.
