VIRUSES! A Trojan horse virus is a computer program that either pretends to have, or is described as having, a set of useful or desirable features but actually contains a damaging payload. True Trojan horse viruses are not technically viruses, since they do not replicate; however, many computer viruses and worms use Trojan horse tactics to initially infiltrate a system. Although Trojans are not technically viruses, they can be just as destructive A computer worm is a standalone malware computer program that replicates itself in order to spread to other computers. Often, it uses a computer network to spread itself, relying on security failures on the target computer to access it. Unlike a computer virus, it does not need to attach itself to an existing program. Worms almost always cause at least some harm to the network, even if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a Malware, short for malicious (or malevolent) software, is software used or created by attackers to disrupt computer operation, gather sensitive information, or gain access to private computer systems. It can appear in the form of code, scripts, active content, and other software.[1] 'Malware' is a general term used to refer to a variety of forms of hostile or intrusive software.[2] Computers can get viruses from downloading and opening an infected file. Computers can also get a virus from an email that was sent to your inbox.

SoftWare The Basic Input Output System (BIOS) or boot loader which defines the firmware interface and loads the OS; The device firmware that controls the operation and performance of the computer hardware; The operating system (OS) which allows the user to interact with the hardware and get the desired outcome by carrying data between RAM and storage disks, displaying the desired result on the output device (monitor/LCD) and by acting as the platform to allow various other system and application software to run on the computing device; Various utility software that regulate the computer functionality by analyzing its performance, configuring and optimizing its processes and, thereby, carrying out system maintenance functions.

The first PC The Computer Museum in Boston asked that question in 1986, and held a contest to find the answer. Judges settled on John Blankenbaker’s Kenbak-1 as the first personal computer. Designed in 1971, before microprocessors were invented, the Kenbak-1 had 256 bytes of memory and featured small and medium scale integrated circuits on a single circuit board. The title of first personal computer using a microprocessor went to the 1973 Micral. Designed in France by André Truong Trong Thi and Francois Gernelle, the Micral used the Intel 8008 microprocessor.

Computer Timeline 1936 Konrad Zuse independently invents the first programmable computer in Germany; the Z1. However, the Zuse computers were destroyed in bombings during World War II. 1937 J.V. Atanasoff builds a machine that stores data as a charge in a capacitor, which is a precursor to RAM. 1944 Mark I, the first programmable, digital computer, is built as a collaboration between Harvard and IBM. 1946 ENIAC, or Electronic Numerical Integrator and Calculator, is funded by the US government to help with the World War II effort. It employs 18,000 vacuum tubes and requires manual patching to program. 1949 EDVAC is the first stored-program computer. 1951 UNIVAC is the first commercial computer. 1953 Grace Hopper invents the first high-level computer language, which later becomes COBOL. She also invents the first compiler to translate computer language to binary. 1961 The IBM Stretch computer reduces the computer's size from over 50 feet to down to 30. 1966 Hewlett-Packard releases its first PC, the HP-2115. 1970 The Intel 1103 is the first computer to utilize RAM. 1971 The Intel 4004 Computer Microprocessor is the first microprocessor. 1973 Ethernet is created for computer networking. 1976 Apple I is the first home computer, sold as a do-it-yourself kit for $600. 1981 IBM releases a home computer, the IBM PC. 1981 Microsoft introduces MS-DOS. 1983 Compaq introduces the first PC-clone computer compatible with IBM. 1983 The Apple Lisa Computer is the first home computer with a GUI, or graphical user interface. 1984 The Apple Macintosh Computer is a more affordable GUI-based home computer. 1985 Microsoft releases the first version of Windows. 1985 Dell introduces its first computer, the Turbo PC. 1986 IBM introduces the first laptop computers, known as PC Convertibles. 1994 IBM introduces the first laptop computers with integrated CD-ROMs; the IBM ThinkPad 775CD.

The first Laptop It weighed ~25 pounds, had a 5-inch screen, and cost $1,800. Technically, this was the first "portable" computer. It wasn't until a couple of years later that the term "laptop" was actually used. Built by Alan Kay.
