A computer virus is a type of malicious code or program written to alter the way a computer operates and is designed to spread from one computer to ANOTHER. A virus operates by inserting or attaching itself to a legitimate program or document that supports macros in order to execute its code. In the process, a virus has the potential to cause unexpected or damaging effects, such as harming the system software by corrupting or destroying data.

Answer:

a)

Explanation:

a)  Operator precedence determines which operator is performed first in an expression with more than ONE operator with different precedence. Associativity is used when two operators of same precedence appear in an expression

Operator Precedence: Operator precedence is the priority of the operators used in an expression. In COMPUTERS, operator precedence is ALMOST as equal to the precedence in Mathematics (BODMAS - Brackets of Division MULTIPLICATION Addition and Subtraction). The only difference is that Division and Multiplication have the same precedence.

Operator Associativity: There are two types of associativity.

1) Left Associativity - The operations start from left to right.

2) Right Associativity - The operations start from right to left.

Answer:

A BRIEF COMPUTER HISTORY

The computer as we know it today had its beginning with a 19th century English mathematics professor NAME Charles Babbage.

He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on.

Generally speaking, computers can be classified into three generations. Each generation lasted for a certain period of

TIME,and each gave us either a new and improved computer or an improvement to the existing computer.

First generation: 1937 – 1946 - In 1937 the first electronic digital computer was built by Dr. John V. Atanasoff and Clifford Berry. It was called the Atanasoff-Berry Computer (ABC). In 1943 an electronic computer name the Colossus was built for the military. Other developments continued until in 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built. It is said that this computer weighed 30 tons, and had 18,000 vacuum tubes which was used for processing. When this computer was turned on for the first time lights dim in sections of Philadelphia. Computers of this generation could only perform single task, and they had no operating system.

Second generation: 1947 – 1962 - This generation of computers used transistors instead of vacuum tubes which were more reliable. In 1951 the first computer for COMMERCIAL use was introduced to the public; the Universal Automatic Computer (UNIVAC 1). In 1953 the International Business Machine (IBM) 650 and 700 series computers made their mark in the computer world. During this generation of computers over 100 computer programming languages were developed, computers had memory and operating systems. Storage media such as tape and disk were in use also were printers for output.

Third generation: 1963 - present - The invention of integrated circuit brought us the third generation of computers. With this invention computers became smaller, more powerful more reliable and they are able to run many different programs at the same time. In1980 Microsoft Disk Operating System (MS-Dos) was born and in 1981 IBM introduced the personal computer (PC) for home and office use. Three years later APPLE gave us the Macintosh computer with its icon driven interface and the 90s gave us Windows operating system.

As a result of the various improvements to the development of the computer we have seen the computer being used in all areas of life. It is a very USEFUL tool that will continue to experience new development as time passes.

ANSWER:

Since the late 1970s, desktop computers used in the home and office have evolved into sophisticated systems that help us get our jobs DONE,deliver information ,and provide entertainment. Presents a timeline of some of the key technologies that have contributed to the evolution of multimedia computers. Do not worry if some of these terms, especially the ones pertaining to hardware , seems unfamiliar to you right now, because they will be discussed in detail later in this book. The main point is multimedia technology did not happen overnight.

Multimedia technology has changed the way we look at computers. The first computers were seen as single-purpose machines that solved incredibly complex mathematical problems. During the 1960s , mainframe computers were used to manage large corporate databases and financial systems. The 1970s saw computer terminals throughout an organization being used for

publishing and information management. The 1980s brought the desktop computer so everyone could have a computer at his or desk for word processing, spreadsheets, and even games. Bringing the computer to the INDIVIDUAL in the office, the home, and the classroom meant LOOKING at the computer as more than just a FANCY typewriter or automated bookkeeper.

In the mid 1980s and into the 1990s, computer developers started looking at how computers could be used a s never before. At the same time, advances in technology brought about:

1. Faster desktop computers

2. Increased working memory capacity in computers

3. Higher data storage capacity in disk drives and CD-ROMs

4. Digital audio and video

5. Graphic operating systems that worked by pointing and clicking at objects on the screen instead of having to remember cryptic command sequences such as “dir .exe” to find a program

6. Local and wide area networks that connected users to the world

7. Thousands of applications ranging from word procesors to a myriad of multimedia products that have changed the workplace,classroom,and the home.

Computer developers started looking to multimedia – the delivery of information using text,pictures,audio,and video—as a way to utilize computers in a uniquely personal way. Multimedia computers could be used to increase efficiency and productivity on the job, provide information at out fingertips in the home, and help students learn more effectively both in and out of the classroom.These personal gains meant that people would see computers as practical and useful tools in their everyday lives.
