Computer Science


It is for beginners in computer science and people interested in a more formal study of computer science. This course covers fundamental concepts that can be applied to any software or computer system, and how to apply concepts to solve everyday problems. Computer science is considered by many of its practitioners to be a foundational science - one which makes other knowledge and achievements possible.

This is a flexible programme, allowing students to study at their own pace (either part-time or full-time), adjusting the intensity of the learning to suit individual needs. You’ll also be available for technical support after the product is completed, and need to keep abreast of industry news and developments in order to suggest and implement improvements. Your role may overlap with similar IT roles such as web developer, games developer, systems developer or software engineer, or you may find yourself working in tandem with these professionals to achieve mutual goals. You’ll need to make sure the ICT facilities meet the needs of your company and are current, while remaining within a set budget, and within all relevant software licensing laws.

The factorial module does only one task; it returns the factorial of the value given. The calling module, combinations, sends the minimum information that factorial needs—one number. Functional independence is measured using two criteria, cohesion and coupling. Microarchitectures contain additional nonarchitectural state to either simplify the logic or improve performance; we point this out as it arises. So this short time between input signal changes would not cause any timing problems.

New Approach To Flexible Robotics And Metamaterials Design Mimics Nature, Encourages Sustainability

With a distinctive anodized aluminum case, and hailed as the first true 64-bit personal computer, the Apple G5 is the most powerful Macintosh ever released to that point. While larger than the previous G4 towers, the G5 had comparatively limited space for expansion. Virginia Tech used more than a thousand PowerMac G5s to create the System X cluster supercomputer, rated #3 in November of that year on the world’s TOP500 fastest computers. Apple makes a splash with its Bondi Blue iMac, which sells for about $1,300.

Computer Graphics

The first use of SIMD instructions was in vector supercomputers such as the CDC Star-100 and the Texas Instruments ASC in the early 1970s. Vector processing was especially popularized by Cray in the 1970s and 1980s by attached vector processors such as those produced by the FPS , and by supercomputers such as the Thinking Machines CM-1 and CM-2. Sun Microsystems introduced SIMD integer instructions in its VIS instruction set extensions in 1995 in its UltraSPARC I microprocessor; the first widely deployed SIMD for gaming was Intel’s MMX extensions to the x86 architecture. IBM and Motorola then added AltiVec to the POWER architecture, and there have been several extensions to the SIMD instruction sets for both architectures.

A similar role to an IT consultant, aninformation systems manageris usually a full-time member of staff, responsible for the secure and effective operation of computer systems within their company. Apple introduces the Macintosh with a television commercial during the 1984 Super Bowl, which plays on the theme of totalitarianism in George Orwell´s book 1984. The ad featured the destruction of “Big Brother” – a veiled reference to IBM -- through the power of personal computing found in a Macintosh. The Macintosh was the first successful mouse-driven computer with a graphical user interface and was based on the Motorola microprocessor. Applications that came as part of the package included MacPaint, which made use of the mouse, and MacWrite, which demonstrated WYSIWYG word processing.

Even after computers were commercialized around the 1950s, most computers were “hosted” in highly secured data processing centers, and users accessed the host computers through “dumb” terminals. By the late 1960s, IBM became a dominant vendor of large-scale computers called a “mainframe” host. In the mid-1970s, minicomputers started challenging mainframe computers. In many cases, minicomputers could host applications and perform the same functions as mainframes, but with less cost.

Memory & Storage

The size of a computer that a person or an organization needs depends on the computing requirements. Clearly, the National Weather Service, keeping watch on the weather fronts of many continents, has requirements different from those of a car dealer's service department that is trying to keep track of its parts inventory. And the requirements of both of them are different from the needs of a salesperson using a small laptop computer to record client orders on a sales trip.

Ibm Introduces Its Personal Computer Pc

Operators directed actions by touching a light gun to the SAGE airspace display. The air defense system used two AN/FSQ-7 computers, each of which used a full megawatt of power to drive its 55,000 vacuum tubes, 175,000 diodes and 13,000 transistors. DEC is founded initially to make electronic modules for test, measurement, prototyping and control markets. Headquartered in Maynard, Massachusetts, Digital Equipment Corporation, took over 8,680 square foot leased space in a nineteenth century mill that once produced blankets and uniforms for soldiers who fought in the Civil War.

The PC Jr. is marketed as a home computer but is too expensive and limited in performance to compete with many of the other machines in that market. It offered increased performance and storage capacity over the original IBM PC and sold for about $4,000. It also included more memory and accommodated high-density 1.2-megabyte 5 1/4-inch floppy disks.

Computers are classified according to computing power, capacity, size, mobility and other factors, as personal computers , desktop computers, laptop computers, minicomputers, handheld computers and devices, mainframes or supercomputers. For example, a mouse and a microphone are input devices used to record user activities and transform them into data that is transmitted to the system unit. A hard disk is a storage unit where data is stored and accessed by other devices.
