in IAS computer IAS stands for

The memory of the IAS consists of 4,096 storage locations, called

In IAS architecture each word consisted of …. Bits

In IAS architecture Word formats. Each number is represented by a sign bit and a …. bit value

In IAS architecture each instruction consisting of …. bits consisted of operations code (opcode)

In IAS each instruction …. bits of address bit address designating one of the words in the memory

....Contains a word to be stored in memory or sent to the I/O unit, or is used to receive a word from memory or from the I/O unit

Specifies the address in memory of the word to be written from or read into the MBR

.....operates the IAS by fetching instructions from memory and executing them one at a time

Contains the 8 bit opcode instruction being executed

Employed to hold temporarily the righthand instruction from a word in memory.

Contains the address of the next instruction pair to be fetched from memory.

Employed to hold temporarily operands and results of ALU operations.

The IAS operates by repetitively performing an instruction cycle: …. steps

.....is smaller, cheaper, and generates less heat than a vacuum tube, can be used in the same way as a vacuum tube to construct computers

Memory arrays are built as an array of byte cells

Each cell stores 1 byte of data.

Specified by their size (depth x width) and the number and type of ports

All memories have …. Ports

Each port gives read and/or write access to …… memory address

Single ported memories can access several addresses simultaneously
