SCSI offering mandatory parity checking improvements over SCSI-1.
IDE (Integrated Drive Electronics) –
It was developed from ST-506 type hard drive
interface, utilizing BIOS INT 13h hard drive with secondary software and supports two hard
drives (Master and Slave). This device does not need extra software to run it since it is
directly initiated in the BIOS. Data transfer rate is 4.1 Mbps. Take note that this
interface cannot support other drives like a CD-ROM drive.
IEEE (Institute of Electrical and Electronic Engineers) –
It is an international
professional society that issues its own standard, and is a member of ANSI and ISO.
Popular known standards is:
IEEE802.3
– is a physical layer standard for 10Base-T,
100Base-T, Ethernet, and StarLAN.
IEEE802.5
– is a physical layer standard for Token Ring.
IEEE802.11
– is a physical layer standard for Wireless
LAN/WAN compatibility.
IEEE802.12
– is a physical layer standard for 100VG AnyLAN.
LAN (Local Area Network) –
A data communications network spanning a limited area. It
provides communications between three or more computers and peripherals, in most
cases using a high-speed media as its backbone.
Keyboard –
This is a component that comes in direct contact for you with your PC. The
mechanism of keyboard converts a key cap’s movement into a signal sent to the computer.
The most common key mechanisms are “
capacitate
” and “
hard contact
“. Capacitate
keyboard has a spring that causes the plastic and the metal plunger to move nearer to two
pads that have large plates (plated in tin, nickel, and copper). These pads are connected
to the keyboard’s printed circuit board. Hard contact keyboard causes the key cap to
collapse a foam rubber dome that presses against a sheet of plastic on the bottom of
which is metallic area connected to the rest of the keyboard’s circuit board.
LDCM (LANDesk Client Manager) –
With the help of LDCM, PCs that are either
stand-alone or on a network can not escape the control of a system administrator. Alerts
will be sent to the user if an abnormal condition is encountered in a PC. It allows the
administrator to give each PC a thorough check-up. Additionally, this feature is available
to multiple OS’s on the market today. LDCM Key Features include the following :
