  1. Computer Hardware and Storage

  2. Buying Computer Hardware

  3. Example 1 • A state agency added office space for new employees. To connect the employees to its network, the agency purchased 25 desktop computer systems at $1,689; 25 network cards at $75; network cabling for $625; two other network devices at $96.88 and a network printer for $5,598 • The cost of installing each computer, connecting it to the network hardware and cabling was $11,890. What was the total cost of the hardware installed?

  4. Solution • 25 x $1,689 = $42,225 (Cost of Desktop Computers) • 25 x $75 = $1,875 (Cost of Network Cards) • 2 x $96.88 = $193.76 (Cost of Network Devices) Add costs of all hardware and installation. $42,225+ $1,875 + $193.76 +$625+$5,598+$11,980 =$62,406.76 Total Cost of Hardware

  5. Leasing Computer Hardware

  6. Example 2 • Thornton College decides to create a new computer laboratory of 35 networked desktop computers. One company offers to lease the desktops to the college for $38.89 per month each for three years. What would be the total cost of the lease?

  7. Solution • 3 x12 = 36 (Number of months lease will last) • 36 x #38.89 = $1,400.04 (Cost of leasing computer for 3 years) • 35 x $1,400.04 =$49,001.40 (Total lease cost of all computers for 3 years)

  8. Cost of Buying Software

  9. Example 1 • Brandon Glass Corporation is considering their desktop operating system software from Lenox version 3.5 to Lenox version 4.0 for their 43 computer systems. The per-copy cost of the upgrade is 97.89. • A 50—workstation upgrade license costs $3,800. How much would Brandon save by buying a 50-workstation upgrade license instead of separate copies of the upgrade?

  10. Solution • 43 x $97.89 = $4,209.27 (cost of upgrading each workstation • $4,209.27 - $3,800 =$409.27 (savings using 50 workstation license)

  11. Developing Software

  12. Example 1 • A new program contains 3,360 lines of code. Three programmers were paid $47 an hour to work on the program and averaged lines of finished code in an 8-hour day. How long did the project take? What was the programming cost of the project?

  13. Solution • 3 x 28 = 84 (lines of finished code per day) • 3,360 / 84 = 40 (number of days the project took) • 3 x 8 = 24 (hours programmers worked in a day) • 24 x 40 =960 (total hours needed to complete the project) • 960 x $47 = $45, 120 (total cost of programming of the project)
