Integrated circuits (ICs) were first introduced during the third generation of computers. The third generation of computers, which emerged in the 1960s, saw the development and widespread use of integrated circuits. These tiny electronic circuits contained multiple transistors, resistors, and capacitors on a single semiconductor chip. The use of integrated circuits significantly reduced the size of computers, increased their processing speed, and improved their reliability, marking a significant advancement in computer technology.

1. LCD panel types include normal and roof-mounted.

2. Liquid Crystal Display flats are thinner and lighter making them more useful and easier for users than CRTs. It consumes less power than CRT.

1. Digital Versatile Disc (DVD), sometimes also known as Digital Video Disc (DVD), is an optical disc storage media format for storing digital data.

2. DVD offers higher storage capacity than compact disc (CD) when having the same size.

3. It is a digital optical dose storage format. It can be used for storing video, audio, images or data.

The CPU (Central Processing Unit), motherboard, and RAM (Random Access Memory) are internal components of a computer hardware system. These components are essential for the computer to function and are located inside the computer's casing.

Dot matrix printers use printer ribbons. A dot matrix printer is a type of impact printer that produces characters and images on paper by striking a series of dots against an ink-soaked ribbon. The ribbon transfers ink onto the paper to create text and graphics. Dot matrix printers were widely used in the past for tasks such as printing invoices, receipts, and multipart forms.

Laser printer resolution is specified in terms of DPI, which stands for Dots Per Inch. DPI refers to the number of dots a printer can place within one square inch of space on a printed page. Higher DPI values generally result in sharper and more detailed printouts. Laser printers typically offer higher DPI resolutions, such as 600 DPI or 1200 DPI, leading to high-quality text and graphics output.
