Multimedia PC with:-

Intel Pentium Processor II

133 Mhz Processor

 4 Gb Hard Disk Drive

3.5” 1.44 Mb Floppy Drive

14” SVGA Monitor

CD ROM Drive

  • Explain the terms above and why this may be the “minimum specification” for the intended purpose. State what other options are available, which may be better in the long term.

Intel Pentium Processor II is a silicon chip that contains a CPU (central processing unit) also called a microprocessor. Sometimes referred to simply as the CPU or central processor, the processor is where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system. Intel Pentium Processor II is manufactured by Intel.

Though still in production, this may be the minimum specification for the intended purpose.  The Pentium II processor has been superseded by the Pentium III microprocessors, since 1993 and more recently Intel has developed the Pentium 4 microprocessors.

133 MHz Processor is the clock speed of a microprocessor and is measured in megahertz. A 133 MHz executes 133 million cycles per second. Each computer instruction requires a fixed number of cycles, so the clock speed determines how many instructions per second the microprocessor can execute.

This may be the minimum specification for the intended purpose. The 3.06 GHz Processor has superseded the 133 MHz Processor.

4 GB Hard Disk Drive is a mechanism that reads and writes data on a hard disk. Hard disk is a magnetic disk, on which you can store computer data. This hard disk can store 4 gigabytes of computer data.  GB is short for gigabyte and is the unit of measurement. 2 to the 30th power (1,073,741,824) bytes. One gigabyte is equal to 1,024 megabytes.

This may be the minimum specification for the intended purpose. The 4 GB hard disk drive has been superseded by the Western Digital Caviar WD2000JB 200 GB hard disk drive.

3.5” 1.44 Mb Floppy Drive is Short for floppy disk drive (FDD), it is a disk drive that can read and write to floppy disks. 3.5” is the size of the floppy disk that can be accessed in a floppy drive. 1.44MB (high-density) is the maximum storage capacity  of data for a floppy disks. MB is short megabyte, Megabyte is frequently abbreviated as M or MB and is the unit of measurement. When used to describe data storage, 1,048,576 (2 to the 20th power) bytes. The most common sizes for PCs are 720K (double-density) and 1.44MB (high-density).
