CS1A 1st test review

Carries the instructions that specify read or write commands

Either software or hardware device that secures a network by blocking unauthorized access

Internal Bus, CPU and Memory

Binary, Octal & Hex to Decimal

Zetta is greater than yotta

The Fetch-Decode-Execute cycle continues until all instructions are executed.

File transfers between 2 systems

Converts the digital computer signals into analog signals that be transmitted over phone lines

Developed the Colossus, Broke the Lorenz SZ code (“TUNNY”), First Fully Functioning Digital Electronic computer

Contains the current instructions being processed

MAN related Tech

Napier’s Rod( or Napier’s Bones) simplify multiplication, Division, Square & Exponent.

Protocols are a set of rules that describe how data will be formatted and processed

When you want to run the app, the operating system loads the code into ROM

MS office, database programs, word processors, games

Why Decimal is a great system because it is easy to deal with large quantities with relatively few symbols

Eliminates the need for multiple versions of the same file, dedicated to rapid storage and retrieval of shared data

1. Requirements phase 2. Design phase 3. Implementation phase 4. Testing 5. Maintenance

WWAN related Tech

High-level programming language

Developed the first “compiler” for high level languages

First to advocate use of the binary number system

Who invented the slide rule?

Sum from D5 to E13

The CPU transfers data, addresses and instructions to/from main Memory via the system bus

Which were Charles Babbage primary inventions that contributed to the progression of modern day computers?

A small group of computers (nodes)

Who invented the ENIAC & UNIVAC

How many instructions can we have if a computer with four switches?

What is the earliest known Mechanical Analog Computer?

Fetches and Interprets instructions, Executes instructions in order

77 base 10 Decimal to Hex

Using ctrl combination—down

Email

For Generations of Computing, Consumers perspective based on major technological development

Different computers have different functions

Manage the systems hardware resources

Messages are divided into fixed-sized, numbered pieces - these pieces are called packets

Four-group series of numbers separated by periods

The bridge manages traffic between the Expansion bus and the CPU

All nodes are logically connected in a loop

Places the instructions in the instruction register (IR)

“Bootstrap” is on the ROM (Read Only Memory) chip

Each node is connected to every node. Internet is based on this topology

Systems software bridges the gap between hardware and applications software.

If I have 5 wires, how many addresses do I have?

Used Punch Cards from Jacquard’s Loom to program computers

In 1968, Doug Engelbart invented a small pointing device he called it a mouse

Each node checks the address on the message and retrieves it if it is necessary otherwise ignores it

Hollerith's desk need for accounting in the 1890 census

All data flows through one centralized device, like a hub or a switch

Enhance the computer’s operation and safeguards data

Expressed in Cycles per second or Hertz(Hz)

First Turing Complete Computer Built, Based on Atanasoff's Work, Calculated Firing Tables, Calculated Firing Tables

Originally used coaxial cable. Then moved to twisted pair or 10-base-T

To execute a program, it must first be copied from the hard drive into RAM

HDD compared to SSD is much faster, more durable, quieter and runs cooler

35 base 10 decimal to binary
