Description

CDROM / Compact Disk Read Only Memory – An optical 120mm diameter disk with 650megabytes capacity. It is used to store text, graphics, sound and video. The digital data is recorded in a spiral from the centre to the outermost edge
CMOS / Complimentary Metal-Oxide Semi-conductor: A low power using memory chip in personal computers the holds time, date and other critical system startup information
DMA / Direct Memory Access: A method of allowing the peripherals to bypass the processor and send blocks of data to a secured memory location. This can speed up data transfer operations enormously.
driver / Operating systems and applications use a general system call to operate hardware devices. The driver is a software routine that translates it into the specific instructions needed to control the hardware device.
DVD / Digital Versatile Disc: 120mm optical disc with a capacity of 4.7 gigabytes. Expected to replace CDROM.
Firewire / A fast (up to 50megabyes per second) serial bus with support for 63 hot swap, plug and play devices. Has the potential to replace serial, parallel, IDE and SCSI Hard disk type interfaces.
IRQ / Interrupt Request: Hardware devices can gain some processor attention by sending a signal via the interrupt request line. Early devices required some knowledge of interrupts to avoid conflicts. Plug and Play now handles the setup of a new device’s communication channels with the rest of the system including the IRQ.
PS/2 / A 6 pin mini DIN socket on most computers used for the mouse and keyboard.
RS232 / Recommended Standard 232C: now ratified as the EIA-232 standard, which is used by all dial-up modems. The serial port may be either 25pin or 9pin D shell.
USB / Universal Serial Bus: An external peripheral interface with a 12Mb transfer rate. It supports up to 127 hot swappable, plug and play devices. It is expected to replace the standard serial and parallel ports

Install Software Programmes - software maintenance log

It is important to maintain a record of the software maintenance carried out on a computer. There are a number of reasons for this:

  • Assists in maintaining software licence control
  • Assists in troubleshooting software problems
  • Provides a “software history” for the computer

Design a software maintenance log
Design a form to record the installation and modification of software installed on your system. This form should include fields for the following information:

  • Details of the system to which log refers
  • Location of system
  • Details of installation (name of package, version, and any other details eg uninstall, reinstall, new install, upgrade, configuration change)
  • Name of Support Person undertaking the work
  • Date of installation/modification. You may use the following example as a guide:

Software Maintenance Log
PC Make/Model / Location
PC Serial No.
Date / Software Package and Version / Type of Maintenance* / Name / Signature
