Mainframe Computers Have Very Powerful Processors Computer Science Essay

The function of computing machine system varies harmonizing to the maps it is used for. See about the different employees with assorted duties. Identify the different official duties or undertakings which are being performed by those employees utilizing their office computing machine systems.

Assume that you are responsible in making the system design specifications for new office computing machines. Provide system specifications for the identified employees and pupils ‘ research lab while sing different types of computing machine system which are most suited for them. See the computing machine input, end product and other hardware devices and the necessary package to fulfill the user demands.

Measure the suitableness of the above system planing specifications for the given scenario by sing factors such as public presentation, costs, client demands, compatibility, capacity, handiness etc.

Assume that you are traveling to plan a new computing machine research lab for the institute. What sort of wellness and safety issues you have to pay your attending on and how to get the better of them? Prepare usher lines to keep a safety research lab environment sing the computing machine biotechnologies.

Mainframe computing machines have really powerful processors and big internal memory. Mainframes are used by big concerns ( Bankss, Companies, universities ) . Mainframe computing machines can besides multi-task by running more than one plan at the same clip. This is known as multi-programming and with more memory has become possible on desktop and laptop computing machines.

Desktop Computer

A desktop computing machine is the most common sort of Personal computer. It has so many different hardware devices. Desktop computing machines can non be easy moved. Processor, memory, proctor, keyboard mouse difficult disc thrust, floppy disc thrust, CD/DVD thrust, talkers are the chief constituents of the desktop computing machines.

Laptop or Notebook Computer

Figure 4

Figure A laptop computing machine is a little, and can easy transport with user. It can be powered by battery or brinies power. A laptop computing machine has a keyboard, trackballs, touch tablets or path points. They are needed because laptop computing machines are frequently operated in topographic points where it is infeasible to utilize a mouse. Laptop computing machine has an LCD or TFT screen and a set of little talkers. Peoples use laptops for working when they are on the move, traveling to meetings or go toing classs. Laptop computing machines are really easy to utilize than a desktop computing machines.

Palmtop Computer or Personal Digital Assistant ( PDA )

This type of computing machine is increasing in popularity, and is frequently called a Personal Digital Assistant ( PDA ) . A palmtop computing machine is little. It can transport in the pocket. It can hive away contact Numberss, names and references, etc. and besides it has electronic mail and wireless cyberspace access.Palmtop ‘s have little keyboards and particular pen to choose icons. We can come in informations by composing with the stylus. They are powered by batteries and store their informations on removable memory units called flash cards. Word processing, electronic journals, database and spreadsheet package can run on palmtop computing machines.

A computing machine contains several major subsystems. We call them computing machine hardware.

Processor

Processor is the encephalon of the computing machine. Processor is the illumination wafers of Si with bantam integrated circuits and intelligent transistors. Degree centigrade: UsersBashiDesktopdefault.jpeg

Processors are organize into 2 chief constituents,

ALU- Which preforms the existent “ calculating ” – attention deficit disorder, subtract, multiply, divide, less than greater than.

CU- Which handle internal operations and direct the package instructions.

And besides microprocessor has,

Address Bus- send an reference to memory

Data bus- sends informations to memory or receives informations from memory

RD/WR line- tell the memory whether it wants to put or acquire the addressed location

Clock line- lets the clock pulsation sequence the processor

Input Devicess

Input devices are used to supply input to the computing machine that translate words, sounds, images and actions. Degree centigrade: UsersBashiDesktop6.jpegC: UsersBashiDesktop5.jpeg

Memory

There are 2 types of memory used in Personal computers.

ROM ( Read Merely Memory )

This memory is used to hive away system degree plans that should be available to the personal computer at all times.

Ex-husband: -BIOS plan

RAM ( Random Access Memory )

Ram is volatile. When the user turn off the power the information stored in memory is lost. RAM is cheaper than ROM. C: UsersBashiDesktop4.jpeg

Secondary Storage Devicess

Secondary storage is used to hive away informations that is non in active usage. This is slower than primary storage or internal memory. This is non-volatile.

Types of secondary storage

Optical storage

Floppy disc

Hard disc

Flash memory

Mother board

The motherboard comprises of a processor, proviso to repair memory faculties, connections to interface thrusts, connections for ports, coachs, the bit set ICs and some other constituents.

Card types

Video cards- it allows to see words on computing machine screen.

I/O Cards- these are the cards that printer stoppers into.

Accountant cards

Sound cards

Modems

Memory cards

Interface cards

picture gaining control cards

Buss

Buss are used to link CPU to all other constituents. Physically, they are wires on the circuit board which transmit informations between different constituents.

The system coach

I/O coachs

Bit set

On the mother board many engineerings are glued together. These engineerings are integrated on the female parent board utilizing controller french friess, which are on any female parent board.

Popular bit sets

Intel 865G

Intel 915G

Intel 945G express

Intel 965G express

Intel 975G express
