Yeh This research was supported in part by Singer-Link Research Assistant Scholarship in Computer Science and by Grant NGR-21-002-206 from the National Aeronautics and Space.Administration. Abstract An Input-output Control System (IOCS) initiates and controls the input and output processes of an operating system, thereby making it unnecessary for the user to recode any of these processes. Input-Output Control Systems usually,perform the following functions: (l)'file and buffer handling for the creation and maintenance of the file, the -" buffering of the input-output data, and the blocking or deblocking of the records; (2) input-output scheduling for the examination of the result of an I/O activity and the determination of the next I/O activity; (3) generation of the actual I/O programs, including #e channel programs. This report presents a tree-structure design of an IOCS, using double-buffers. The design includes a set of macro instructions and a set of algorithms. There are three levels in the tree-structure: the first level deals with file handling and buffering; the second level with I/O scheduling; and the third level with the device drivers. -

The two's complement of an N-bit number is defined as the complement with respect to 2N, in other words the result of subtracting the number from 2N. This is also equivalent to taking the ones' complement and then adding one, since the sum of a number and its ones' complement is all 1 bits. The two's complement of a number behaves like the negative of the original number in most arithmetic, and positive and negative numbers can coexist in a natural way. In two's-complement representation, negative numbers are represented by the two's complement of their absolute value;[1] in general, negation (reversing the sign) is performed by taking the two's complement. This system is the most common method of representing signed integers on computers.[2] An N-bit two's-complement numeral system can represent every integer in the range −(2N − 1) to +(2N − 1 − 1) while ones' complement can only represent integers in the range −(2N − 1 − 1) to +(2N − 1 − 1). -

Algorithms and Programming Techniques
INTRODUCTION TO COMPUTER SCIENCE 1 (CSC 111) What is a Computer? A computer can simply be described as a powerful electronics device which has the capability of accepting data as (input) in a prescribed format, apply a series of arithmetic and logical operation on the data (processing) and produce the result of these operation as an (output) in a specified format at a very fast speed under the control of a logical sequence of instruction called "PROGRAM". A computer can simply be defined as an electronic device which accepts input (data), process it and gives desired output (information) under the instructions of stored program. From the description above, a computer can be described as an input - process-output (IPO) system, pictorially represented in the figure below Input Processing Output (Data) (Information) Fig. 1 A schematic diagram to define a computer A computer is a system and the word system has several commonly used definitions and meaning. There are for example the digestive system, grading system, electronic system and telephone system among others. In all these, one thing is clear and is the fact that in a system, there is more than one part. A system is an integration of two or more devices that are connected together to form a whole. Therefore, a computer system is a group of devices that under the control of stored programs process data into information. In a more comprehensive form, a computer system can be defined as an electronic machine which under the control of stored programs accepts data through the input device, process it into information which can be stored in its memory for later use or communicated to the user through any available output device. -
The History of the Enterprise Cloud As Seen by an "Old Mainframer”
The History of the Enterprise Cloud as Seen by an "Old Mainframer” SM Navigating Information Technology Horizons Published Since 2001 Report #TCG2014009 April 11, 2014 The History of the Enterprise Cloud as Seen by an “Old Mainframer” Analyst: Stephen D. Bartlett Introduction An interesting fact (to me anyway) is that the IBM System/360 (S/360) is just one month older than the Ford Mustang; the S/360 family was announced on April 7, 1964, and the Mustang in May, both in New York City, by the way. In many ways, the product life of this much-coveted vehicle reminds me of and in many ways parallels the S/360 and the 50-year legacy that it spawned. Both demonstrate longevi- ty, certainly, but these remarkable products always have been changing and improving, and have survived many crises, economic downturns, governmental intrusions, technology revolutions, and multiple threats from many competitive venues. Each has endured because of a consistent corporate vision, the dedica- tion of many talented scientists and engineers, and most of all because of the continued enthusiasm, trust, and confidence of its many customers. Even after fifty years, one can never mistake a Mustang for any- thing but a Mustang. And so it also is with the System/360 and its many successor generations of IBM mainframes. Compared to the mean age of the current flock of IT professionals, fifty years is beyond memory; it may even predate the birth of their parents. My career reference point was set by the announcement by IBM of the System/360, marking its fiftieth anniversary this week. -
