All of the following are stages in the SDLC except JAD. JAD is Joint Application Development.

Explanation:

JAD (Joint Application Development) is a methodology that involves the client or end user in the design and development of an application, through a succession of collaborative workshops called JAD sessions.
The JAD approach, in comparison with the more traditional practice, is thought to lead to faster development times and greater client satisfaction, because the client is involved throughout the development process. In comparison, in the traditional approach to systems development, the developer investigates the system requirements and develops an application, with client input consisting of a series of interviews.
JAD is a process used in the life cycle area of the dynamic systems development method (DSDM) to collect business requirements while developing new information systems for a company.
The JAD process also includes approaches for enhancing user participation, expediting development, and improving the quality of specifications.

Convert the following hexadecimal numbers to decimal: (a) FF (b) F0A2 (c) 0F100 (d) 100

Hatshy [7]

Answer:

a) 255

b) 61602

Explanation:

You need to understand the decimal equivalent of hexadecimal numbers, from 0 to 9 numbers are represented the same way, from 10 to 15 we use the alphabet, meaning 10 equals A in hexadecimal base, 11-B, 12-C, 13-D, 14-E, and 15-F.

For your first exercise you'll enumerate the number's positions fromright to lef begining with 0:

a. F F

position 1 0

Now you'll multiply your hexadecimal number (using the decimal equivalent for your letters) for the base (16) elevated to the number of the position:

$F*16^{0}=15*1=15\\F*16^{1}=15*16=240$

Finally, you'll add your results:

240+15=255

FF=255

b. F 0 A 2

position 3 2 1 0

$2*16^{0}=2*1=2\\A*16^{1}=10*16=160\\0*16^{2}=0*256=0\\F*16^{3}=16*4096=61440\\\\2+160+0+61440=61602\\$

F0A2=61602

c. F 1 0 0

position 3 2 1 0

$0*16^{0}=0*1=0\\0*16^{1}=0*16=0\\1*16^{2}=1*256=256\\F*16^{3}=16*4096=61440\\0+0+256+61440=61696\\$

0F100=61696

d. 1 0 0

position 2 1 0

$0*16^{0}=0*1=0\\0*16^{1}=0*16=0\\1*16^{2}=1*256=256\\\\0+0+256=256\\$

100=256

I hope you find this information useful! Good luck!
