Q. Define COM Programs?
A COM (Command) program is binary image of a machine language program. It is loaded in memory at the lowest available segment address. Program code starts at an offset 100h, the first 1K locations being occupied by IVT.
A COM program keeps itsdata, code and stack segments within same segment. Because the offsets in a physical segment can be of 16 bits hence size of COM program is limited to 216 = 64K that involvesdata, code and stack. The subsequent program displays a COM program:
; Title add two numbers as well as store result and carry in memory variables.
; name of segment in this program is chosen to be CSEG
Factor which helps in analysis of parallel algorithms is the total number of processors needed to deliver a solution to a provided problem. So for a given input of size let's say n

Q. Limitations of execution of instructions? 1. Size of memory shown in 16 words while instruction is capable of addressing 210 =1 K words of Memory. However why 210 since 10 b
Functional units of a computer system: Digital computer systems consist of 3 distinct units. These units are as follows: Central Processing unit Input unit and Output unit.
What are semaphores? Semaphore : A semaphore is a synchronization tool which gives a general-purpose solution to controlling access to critical sections. It s an abstract data
Q. Programming with parallel virtual machine? The general method for writing a program with PVM is like this: A user writes one or more sequential programs in C++, C or FOR
How many address bits are required to represent 4K memory ? Ans. 12 address bits are required for representing 4K memory, as 4K = 2 2 x 2 10 = 2 12 Therefore 1K = 1024
