difference between Mainframe architecture and Client/server architecture?

Answer 1

mainframe architecture was created by these briliant developers to counter the problems that they faced those days in the performance and security issues..
Client/server architecture was created by these "dumb" people thinking that they can re-counter a solution already created by someone. in which at the end, the problem got worse.
Anyway, both these architecture are actually the same, just the main difference is the size of the servers.
Mainframes are used in data centers mainly.
while client server is used almost in every corporate environment

Answer 2

Answer 4

In Mainframe all the computing happens in the Mainframe itself.

The user 'log-in' via a 'dumb' terminal that only needs to send every keystroke to the Mainframe and display what the Mainframe sends back.

This is typically a LOT more secure because the 'dumb terminal' only needs to have a keyboard/mouse and screen (no floppy/CD drive, no USB ports etc) - so there is no way to 'upload' or 'download' data.

Disadvantage is that everything is held on the Mainframe - if the network is out or too many users logged on or whatever, too bad, there is nothing you can do.

In Client/Server (normally) all the computing happens at the users end i.e. on their own PC ('Client')

The 'Server' is used mainly for file & data storage and other 'common' resources (such as Printer & www access). So the Server has to check that the users have access rights & permissions to the data (eg. emails) and resources.

Advantage is that you can work 'off-line' and only need to 'log-on' when you need access to common resources.

Disadvantage is that chaos rules (the boss never knows where the latest version of the document is held and who might have local copies or who has walked away with a CD's worth of customer data) - plus Users are able to infect the network,Server and other users PC's with worms & virus by bringing it in from home ...

I'll start up with Architecture (I take up Architecture in College and planning to to take engineering too). Architecture is an art and science of building. It is the basic definition of it. It involves in planning, designing and construction that's why it's science. We need to know the technical aspect to build the structures. (THIS IS CONTRARY TO POPULAR BELIEF). We study the wind path, solar path, existing terrain vegetation and structures. ecological impact of building. We acquire these data to address comfort within the structure. We also have this term "Imagineering" which means that we evolve our ideas, plans, concepts into reality through engineering. Stressing the point that it's both art and science. Although there are designs that are yet purely imaginative. . . .But may some day be real. It could start out that way. AS to ART, building design can be whimsical or formal reflecting designers' philosophy and ideals. It could reflect certain times general philosophy, belief and social behavior. Architecture address mans desires to connect with their gods and be one with the community they belong. It involves beauty. Vitruvius answer it all by his book De Architectura : “firmitas, utilitas, venustas” (strength, utility and beauty). Architecture must be firm, stable. Architecture must be functional. It must serve it's purpose whether it be a monument, a staduim, simply a kiosk or a waiting shed. Architecture must pose beauty whether it be beauty emphasizing natural materials, classical or minimalist. Where as CIVIL Engineering, focuses on technical aspects of building - The math that evolves in structures - tensile stress, compressive stress, elasticity. momentum, etc. They dealt more on stability and functionality of structures. Plus the civil comes from latin civilis meaning citizen. They involve civic works such as roads, highways, bridges. Although architects can also design road network for community planning. Engineering is highly needed with this can kind of stuff. Both professions design, plan and involve in construction. They can both become construction managers. They all follow the building code. Then, where is the thin line between these professions? Architects are authorized to perform architectural works - floor plans, elevation of buildings, sections, landscaping, building materials, interior ( they may require another license). It's the over-all look of the building. Whereas Civil Engineers (Structural engineers) involves structural works as such building foundation, footing, trusses, what sizes and types of metals, etc. You got the idea! It's about the stability of the structure! Architects and Civil engineers comprises from one another so that the structure where in fact viable for actual building.
