## Information Technology Fundamentals (ITF)

Mr. Shultz

### Today’s Bell-Ringer and Objectives

Bell-Ringer

Objectives

• Given the FBLA national web site, TSW correctly identify the purposes and goals of the student organization with no errors. (BUS6670.030)

### Bell-Ringer

first letter of first name

last name

three numbers (usually 001)

Example: sshultz001

### Bell-Ringer

First Initial (capitalized)

DOT

Last Name (capitalized first letter)

Four-digit number like 0904

Example – S.Shultz0904

### Bell-Ringer

Same as user name, BUT

Add a “1” at the end

Example – S.Shultz09041

### Today

• Computer Math

• Take the IC3 Living Online Practice Test

• 45 minute limit, take your time

• When done, go FBLA web site link on class page.

### Computer Math

Prefixes:

K = kilo = 1,000 (thousand)

M = mega = 1,000,000 (million)

G = giga = 1,000,000,000 (billion)

T = tera = 1,000,000,000,000 (trillion)

### Computer Math

CPU Speeds

Measured in Hz (hertz)

Means cycles per second

The more cycles it can process, the faster it can run

### Computer Math

1a. If a CPU is rated at 500 MHz, how many cycles can it process in a second?

500 times M (1,000,000) =

500,000,000 (500 million)

### Computer Math

1b. If a CPU is rated at 1 GHz, how many cycles can it process in a second?

1 times G (1,000,000,000) =

1,000,000,000 (1 billion)

### Computer Math

1c. If a CPU is rated at 950 MHz, how many cycles can it process in a second?

950 times M (1,000,000) =

950,000,000 (950 million)

### Computer Math

1d. If a CPU is rated at 1.1 GHz, how many cycles can it process in a second?

1.1 times G (1,000,000,000) =

1,100,000,000 (1.1 billion)

### Computer Math

1e. Which CPU is faster, one rated at 1.1 GHz, or one rated at 950 MHz?

1.1 GHz = 1,100,000,000

950 MHz = 950,000,000

### Computer Math

Hard Drive Capacity

Measured in B (bytes)

Means pieces of data

More bytes on the hard drive = more data you can store

### Computer Math

2a. If a hard drive holds 200 GB, how many pieces of data can it store?

200 times G (1,000,000,000) =

200,000,000,000 (200 billion)

### Computer Math

2b. If a hard drive holds 1TB, how many pieces of data can it store?

1 times T (1,000,000,000,000) =

1,000,000,000,000 (1 trillion)

### Computer Math

2c. If a hard drive holds 750 GB, how many pieces of data can it store?

750 times G (1,000,000,000) =

750,000,000,000 (750 billion)

### Computer Math

2d. You need to have a total of 1TB of storage, and you already have a hard drive that holds 750GB. What is the smallest hard drive you can add and have 1TB of storage?

1TB (1,000,000,000,000) minus

750GB (750,000,000,000) =

250GB (250,000,000,000)
