Benifits of student and teachers in computer?
With all the software out there aimed at College level or K-12 level students, a computer can quickly become a very resourceful tool for many different applications. OpenOffice.org , a free and open sourced program, is equivalent to Microsoft Word (It can even edit .doc files) and is completely free of charge. SchoolHouse, a Mac application, can keep all your appointments and grades in sync...something that I found very useful.

What are the factors that effect the overall processing capabilities of a computer?
Hardware can affect the speed that data is processed. Newer processors will process faster, and newer devices such as hard discs will operate faster and with greater reliability.
All hardware fails eventually.
The hardware may not be up to the specifications that the software requires.
Software can affect data processing. If it is not designed and coded well, it may be slow, use too much resources such as memory or have too many bugs which may cause the data processing to crash.
Software needs to be developed in a proper way, from design through coding, testing and implementation. If changes in circumstances occur in the stage, or it is rushed, then this may result in inefficient programs. Software that has not been properly tested will crash too frequently.
Software may look impressive but is of little use if it is incompatible with other hardware and software, or it does not provide the functions needed.
The operating system needs to be suitable for the system - You could not run a mainframe operating system on a palm-top computer.
The data being processed must be ip-to-date, accurate, relevant and complete. Remember - GIGO - Garbage In, Garbage Out!
Other factors affecting the efficiency of data processing systems :
- poor communications with the user. Problems may not be properly notified.
- poor user ability. Poor ICT skills.
- procedures not in place for trouble-shooting or making adequate backups.
- maintenance procedures need to be in place to keep the system bug-free and adaptable to changing circumstances.
- insufficient investment.
- no proper provision of support.

Which part of the computer is not an output device?
Output devices are those that relay information from the computer the environment or other devices: monitors, sound cards and speakers, etc.
Non-output devices are input devices (such as a keyboard or a microphone input). Not strictly output devices are combined input/output devices such as USB ports, serial ports, etc. Other devices, such as mass storage devices (hard disks, etc) are typically grouped separately from output devices, too.
Memory devices, processing units, and infrastructure devices such as the motherboard chipset, power supply, fans and mechanic parts are all other examples of parts of a computer that are not output devices.
