![]() ![]() Some examples of second generation computers are PDP-8, IBM 1401 and IBM 7090. However, the second generation computers still required air conditioning and manual assembly of individual components into a functioning unit. Moreover, these were more portable and generated less Fundamentals of Computers I-7amount of heat. These computers were more reliable and less prone to hardware failure, hence, they required less frequent maintenance. As a result, programming became less cumbersome. Assembly language uses mnemonics (abbreviations) for instructions rather than numbers, for example, ADD for addition and MULT for multiplication. However, they still relied on punched cards for input and printouts for output.One of the major developments of this generation includes the progress from machine language to assembly language. In second generation computers, magnetic cores were used as primary memory and magnetic disks as secondary storage devices. Computers became smaller, faster, cheaper, energy efficient and more reliable than their predecessors. Definition display By Robert Sheldon What is a display In computing, a display is a device with a screen that shows a rendered electronic image made up of pixels that are illuminated in a way that distinguishes text and graphic elements. Since transistor is a small device, the physical size of computers was greatly reduced. It usually has three leads and performs electrical functions such as voltage, current or power amplification with low power requirements. Logic gates are used in the architecture of our telephones, laptops, tablets, and memory devices. Logic gates are found in nearly every digital gadget we use on a regular basis. Logic gates use Boolean algebra to execute logical processes. A transistor is made up of semiconductor material such as germanium and silicon. The mix of inputs applied across a logic gate determines its output. Second generation computers used transistors, which were superior to vacuum tubes. With smart engineering, transistors helped computers power through huge numbers of calculations in a short time. ![]()
