define a hierarchical system
a srt of interrelated subsystems
define structure
,the way in which components relate to each other
define function
the operation of individual components as part of the structure
what are the 4 basic functions a computer can perform?
- data processing
- data storage (short, longterm)
- data movement (I/O, data communications)
- control
what are the 4 main structural components of a computer?
- CPU: controls the operation of the computer and performs its data
processing functions
- main memory: stores data
- I/O: moves data between computer and external environment
- system interconnection: some mechanisms that provides for
communication among CPU, main memory, and I/O. e.g. system bus
Name and describe each component of a CPU
- control unit: controls the operation of the CPU (meaning it also controls
the computer)
- Arithmetic and logic Unit (ALU): performs computer's data processing
function
- Registers: provides storage internal to the CPU
- CPU interconnection: provides communication among the control unit,
registers, and ALU
what does a multicore computer contain?
- CPU: fetches and executes instructions
- core: individual processing unit or processor chip, equivalent in
functionality to a CPU on a single-chip CPU system, aka specialised
processing units
- processor: a physical piece of silicon containing one or more cores
- interprets and executes instructions
which device was created in the first generation and what was it used for?
vacuum tubes: was used for digital logic elements and memory
Explain the IAS computer
- study was made at princeton and completed in 1952. it is now a
prototype for general purpose computers.
what was the fundamental design approach for the IAS computer?
, - The fundamental design approach was the stored program concept,
which was attributed to Jon von Neumann in 1945 for EDVAC.
what was the second generation of computers?
Transistors
name some facts about transistors
- Relatively Smaller due to a transistor technology
- Relatively Cheaper
- Dissipates less heat than a vacuum tube
- Is a solid state device made from silicon
- Was invented at Bell Labs in 1947
what did second generation computers introduce?
- more complex ALUs and control units
- use of high-level programming languages
which device was introduced in the third generation?
integrated circuits
describe the integrated circuits
- Discrete component Single, self-contained transistor
- Manufactured separately, packaged in their own containers, and
soldered or wired together onto masonite-like circuit boards
- Manufacturing process was expensive and cumbersome
what were the two most important members of the third generation?
IBM System/360 and the DEC PDP-8
which year was the integrated circuits invented?
1958
name the 4 functions of integrated circuits
Data storage - provided by memory cells
Data processing - provided by gates
Data movement - the paths among components are used to move data
from memory to memory and from memory through gates to memory
Control - the paths among components can carry control signals
what are some advantages of later generations' inventions as compared to
early generation inventions
- cheaper
- smaller
- high-level language
which device was created in 4th generation and which years was that?
