(1) Alternatively referred to as PC DOS, IBM DOS is a
text-based operating system similar to Microsoft’s
DOS, but only sold by IBM. DOS is a single-user,
single-tasking operating system with basic kernel
functions that are non-reentrant: only one program
at a time can use them and DOS itself has no functionality to allow more than one program to execute at
a time.

(2) Secondary storage, sometimes called auxiliary
storage, is all data storage that is not currently in a
computer’s primary storage or memory. In a personal computer, secondary storage typically consists of
storage on the hard disk and on any removable media, if present, such as a CD or DVD, flash memory,
floppy disks, magnetic tape, paper tape, punched
cards, standalone RAM disks, and Iomega Zip drives

(3) The kilobit is a multiple of the unit bit for digital
information or computer storage. The prefix kilo (symbol k) is defined in the International System of Units
(SI) as a multiplier of 103
(1 thousand), and therefore,
1 kilobit = 103 bits = 1000bits. However, computers
are binary or base 2, as in ones and zeros. So instead
of counting by tens, they count by 2s. So instead of
1,10,100,1000 it is 1,2,4,8,16,32,64,128,256, 512,
1024

memory and various input/output devices, including
a display screen, keyboard and mouse, modem, and
printer.

that are essential to the correct running of the computer
system. A virus itself is programme software and has
effect basically on software and not hardware. It could
have effect on the systems or Application software to
execute specific instructions on the hardware.

computer. It was Turing-complete, digital, and capable of being reprogrammed to solve a full range of
computing problems. It was designed to calculate
artillery firing tables for the United States Army’s
Ballistic Research Laboratory.

or 1000 (103
) bytes, dependent upon context, in the

computer whose size, capabilities, and original sales
price make it useful for individuals, and which is
intended to be operated directly by an end-user with
no intervening computer operator. This contrasted
with the batch processing or time-sharing models
which allowed larger, more expensive minicomputer
and mainframe systems to be used by many people.

. (2) Assembly language uses a mnemonics to represent each low-level machine operation or opcode.
Some opcodes require one or more operands as part
of the instruction, and most assemblers can take
labels and symbols as operands to represent addresses and constants, instead of hard coding them into
the program.

. (1) A parallel port can be used to connect a large
number of devices. The most common usage was for
printers, although scanners, external disk drives, and
network adapters also used this port. With a special
cable, two computers could also be connected directly for sharing files.

covers a broad area (i.e., any telecommunications
network that links across metropolitan, regional, or
national boundaries) using private or public network
transports. Business an-d government entities utilize
WANs to relay data among employees, clients, buyers,
and suppliers from various geographical locations.
In essence, this mode of telecommunication allows a
business to effectively carry out its daily function
regardless of location.
