All the IT job aspirants, who wish to be Software Developers, Database Administrator and Network Engineers,must attempt AMCAT Computer Science section. So, gear up yourself to grab as much information as possible and take up this section. In general, 2-3 questions from computer architecture definitely come in this section. Also, it hardly takes 45 seconds to solve the problems. The difficulty level varies from easy to moderate.
Furthermore, we will put light on what computer architecture is all about and questions on it.
Overview of Computer Architecture
Since the word architecture, itself refers to structure or design. So, Computer architecture also deals with the computer specifications. It explicitly defines the components like I/O devices, memory structure, processor and sub systems in the body of a computer system.It tells how a set of software and hardware interact to form a computer system.
In other words, computer architecture is solely about how a computer system is designed and what technologies it is compatible with.
Components of Computer Architecture
The main components in a typical computer system are the processor, memory, input/output devices, and the communication channels that connect them.
By all means, the processor is the brain of the system. It is the component that executes a program by performing arithmetic and logical operations on the input data. In a standard computer system there is only one processor, known at the central processing unit, or CPU.
Memory is a kind of passive component that stores information unless it is requested by another part of the system. During generic operations it inputs instructions and data to the processor. In addition, it is the source or destination of data transferred by I/O devices. Information in a memory is accessed through its address. In programming language, memory is a one-dimensional array.
Input/output (I/O) devices:
Input/output (I/O) devices transfer information without altering it between the external world and one or more internal components. I/O devices also act as secondary memories, for example disks and tapes, or devices used to communicate directly with users, such as video displays, keyboards, and mouses.
The communication channels that coordinate the system together are usually simple links that connect two devices or more complex switches that interconnect several components They allow any two of them to communicate at a given point in time. When a switch is configured to allow two devices to exchange information, all other devices that rely on the switch are blocked, i.e. they must wait until the switch can be reconfigured.

Mock AMCAT Computer Architecture Questions
Which memory device is generally made of semi-conductors?
C. Floppy disk
D. CD disk
Answer: Option A
Explanation: Memory devices are usually made of semi conductors for faster manipulation of the contents.
Register renaming is done in pipelined processors
A. as an alternative to register allocation at compile time
B. for efficient access to function parameters and local variables
C. to handle certain kinds of hazards
D. as part of address translation
Answer: Option C
Explanation: Register renaming is done to avoid data hazards
The amount of ROM needed to implement a 4 bit multiplier is
A. 64 bits
B. 128 bits
C. 1 Kbits
D. 2 Kbits
Answer Option D
Explanation: For a 4 bit multiplier, there are 24 * 24 combinations, i.e., 28 combinations. Also, Output of a 4 bit multiplier is 8 bits. Thus, the amount of ROM needed = 28 * 8 = 211 = 2048 bits = 2Kbits

Answer: Option B
A RAM chip has a capacity of 1024 words of 8 bits each (1K × 8). The number of 2 × 4 decoders with enable line needed to construct a 16K × 16 RAM from 1K × 8 RAM is
Answer Option B
Explanation: RAM chip size = 1k ×8[1024 words of 8 bits each]
RAM to construct =16k ×16
Number of chips required = (16k x 16)/ ( 1k x 8)
= (16 x 2)
[16 chips vertically with each having 2 chips horizontally]. So to select one chip out of 16 vertical chips, we need 4 x 16 decoder.
Available decoder is 2 x 4 decoder
To be constructed is 4 x 16 decoder
Hence 4 + 1 = 5 decoders are required.
