The five parts of IS
The change we are seeing in the overall structure of how we interact with IT products is also called the change in
IT infrastructure
From the late 1950s through the 1960s computers were seen as way to more efficiently do calculations. The primary work was to organize and store large volumes of information that were tedious to manage by hand only large businesses, universities, and government agencies could afford them.
The mainframe error
In 1975 the first micro computer was announced on the cover of popular mechanics. The alter 8800. It’s immediate popularity, sparkly imagination of entrepreneurs everywhere, and there were dozens of companies manufacturing these personal computers.
The PC revolution
In the mid-1980s businesses began to see the need to connect their computers as a way to collaborate and share resources
Client server era
What’s the last era discussed
The Internet, World Wide Web and e-commerce
All software uses, at least one
Hardware device to operate
In a computer…. is what makes a computer work
Hardware
Can a computer run without software
Yes
What are the two types of software?
System, software, and application software
Software is developed as a means to enhance our
Lives
Dumb devices to pass on anything received on one connection to all other connections
Hubs
Semi intelligent devices, that learn which devices are on which connection
Switch
Essentially small computers that perform a variety of intelligent tasks
Router
Out of hub switches, and routers, which can be wireless
Routers
Refers to as wired or bounded transmission media. Signals being transmitted, or directed, and confined in a neuropathic by using physical links, features, high-speed secure, use for comparatively shorter distances.
Guided media
Twisted peach cable. Coaxial cable. Optical fibre cable.
Three types of guided media
Consists of two separately insulated conductor wires wound about each other. Generally several pairs are bundled together in a protective sheet. They are the most widely used transmission media.
Twisted pair cable
Has an outer plastic covering containing two parallel conductors, each, having a separate insulated protection, cover, and transmits information into modes. Base band mode and broadband mode.
Coaxial cable
Cable TVs and analogue television networks are widely used with what type of cables
Coaxial
Uses the concept of reflection of light through a chore made up of glass or plastic. The course is surrounded by less than glass or plastic covering called the cladding. It is used for the transmission of large volumes of data.
Optical fiber, cable
Data, redundancy, data and consistency, program, data, dependence, lack of flexibility, poor security, lack of data, sharing, and availability
