PCMainframe 1 PCS Versus Mainframes Although mainframes are not talked about much anymore they are still used in some industries PC s and mainframes can accomplish much of the same things however they way that they work is different There are many aspects that will be discusses including performance cost size operating systems programming networking and maintenanceA mainframe is a very large computer that is often the hub of a system that serves many users The PC originated A PC is a personal computer that is much smaller in size and is built for use by an individual A mainframe s performance is much higher than a PC A mainframe has anywhere from one to 16 CPU s modern machines have more No Author 2010 A PC generally has one CPU that consists of a single dual triple or quad core processor The memory in a mainframe ranges from 128 MB to over 8 GB of online RAM No Author 2010 A PC has similar memory installed in modern days Many PC s can hold up to 16 GB of RAM A mainframe s giving 80 over 550 MIPS power No Author 2010 PC s processing power is based on several factors such as the front side bus the RAM amount and speed and the processor Unlike a PC the storage IO and RAM are often stored in different cabinets The mainframe also has separate processesThe PC runs those processes through the RAM and can only run as many as the memory can handle at one time The cost is much different for a mainframe than it is for a PC The average cost for a mainframe with hardware cost software cost server administration labor cost facilities cost and migration or project changes can total about 40000 Alinean 2008 PC s come in several different formats and prices vary dramatically however they are far more affordable than a mainframe Personal computers can be a desktop computer notebook or tablet PC For a PCMainframe 2 desktop computer or a notebook the prices can range from 250 for a basic set up with low system specifications up to 1000 and up for high end personal computers A tablet PC can cost up to 1700 PC s can be more cost efficient but it depends on what the industry needs Another big difference between PC s and mainframes is the size and amount of space that they take up A mainframe takes up a lot of space One could fit several PC s in that amount of space The number would depend on the type of PC The tablet PC s can range in sizes up to 12 Notebooks are generally 15 to 19 The desktop computer is usually a standard size and takes up more space than the other personal computers The desktop is in multiple parts ie Monitor keyboard mouse speakers etc These parts generally are placed on a desk and will take up as much room as needed The operating systems used on mainframes are UNIX Linux VMS AOS ZV M and VSEESA Mainframe operating systems run on command line input No Author 2010 Most PC s that are being sold now are running Microsoft Windows 7 and are have a graphical user interface Another common operating system is Mac Less used are Linux MSDOS and other versions of Microsoft Windows Programming languages used for PC s include CC Java Falcon Perl ASP BASHBourneAgain Shell and AWK Mainframes are commonly programmed using COBOL Basic AssembLer BAL FORTRAN Assembly Program FAP High Level Assembler HLASM and large general purpose language PLI Wikipedia 2010 Networking for mainframes is more costly than for PC s because mainframes require more equipment and monitoring along with higher maintenance PC networks generally run on a wired or wireless LAN that is cost efficient and can handle as many computers as the bandwidth PCMainframe can handle PC s are usually set up with a Star topology Mainframe networks are set up to handle large networks and are generally set up as a Point to Point topology This is a mainframe terminal that is connected to a mainframe frontend processor A Multi Point topology consists of multipoint links This can be multiple terminals connected to a mainframe frontend pI39OCCSSOI39 Maintenance repairs and upgrades for mainframes cannot usually be done by an operator These things are usually done by a tech professional which is going to be much more costly than for a PC PC maintenance repairs and upgrades are generally simple enough for the owner to do with the instructions This is less costly than taking it to a shop Even if taken to a professional these things are going to be much lower for a PC than for a mainframe The University of North Carolina ND With all of these things taken into consideration one must decide is a mainframe is right for them It depends on the organizations needs and budget Although a mainframe can be beneficial there are a lot of extra costs involved They would also need to have the space needed to house the mainframe and its components PC s take up a lot less room and can be more users friendly The operating systems are more widely known and easier to use as well All of these things need to be considered before making a decision 3 PCMainframe References Alinean 2008 Mainframe Migration Case Studies A Total Cost of Ownership Comparison Retrieved August 1 2010 from httpWWWalineancomPDFsIntel Mainframe
