Gilberto Teodoro, Sr. was the longest serving administrator of the Philippines' Social Security System (SSS) from 1966 to 1986. During his leadership, he launched several new programs that became the blueprint for SSS's success, including educational loans, calamity loans, and investment incentive loans. He also oversaw the decentralization of SSS operations, which sped up loan and benefit processing and increased registration in rural areas by allowing payments through authorized banks instead of requiring in-person visits to the head office. Teodoro's initiatives during his 20 years as SSS administrator helped establish the agency and make it more accessible to Filipinos nationwide.

Microcomputers, commonly known as PCs, they are very small and cheap. The first microcomputer was designed by IBM, it was designed in 1981 and was named IBM-PC. Later, many computer hardware companies copied it and termed their microcomputers as PC-compatible, which means to any PC that is based on the original IBM PC design.
Another type of popular PC is designed by Apple. PCs made by IBM and other PC-compatible computers have a different designing as compared to Apple computers.
Moreover, PCs and PC-compatible computers commonly use the Windows operating system, while Apple computer use the Macintosh operating system (MacOS). However, IBM and IBM-compatible PCs are more popular than Apple PC. These microcomputers can be classified into the following categories
Desktop PC is one of the most popular models of PCs. The desktop PC can be placed on a desk or table. It is widely used in homes and offices. It has physical hardware that makes computer to run and connects to input devices such as keyboard and mouse users interact with. Desktop PCs are mostly used in enterprise, as well as in consumer use cases such as gaming. In the enterprise they are important because they are the main means for many users to do their work. Desktop PC contains Motherboard, Processor, storage devises etc inside it.
Laptops are small microcomputers that can easily fit inside a bag. They are very handy and can easily be carried from one place to another. Hence, laptops are very useful, especially for going on long journeys. Laptops works on a special battery and do not always have to be plugged in like desktop computers. The memory and storage capacity of a laptop is almost equal to that of a desktop computer. As with desktop computers, laptops also have HDDs, floppy disk drives, zip disk drives, etc. For input, laptops have a built-in keyboard and a trackball/touchpad, which is used as a pointing device (as a mouse is used for a desktop PC). But laptops have the same features and processing power and speed as the most powerful PCs. However, there is a problem that laptops are generally more expensive than desktop computers. (TERA GHAR JAYEGA ISSME) These computers are very popular among business travellers
Netbook PC also known as Handheld Computers, In the mid 1990s a wide range of small personal computing devices these are commonly known as handheld computers, Palmtop computers, or Mini-Notebook computers. These computers are called Netbook computers because they can fit in one hand like book, while users can use the other hand to operate them. these computers are very small in size, and hence easy to use
Tablet PC is same as notebook computer and can be operated with one hand, but it can be used by input from a Stylus pen or by directly your fingers instead of the keyboard, mouse. It is a portable computer and user can use it anywhere. Tablet Computer are the new generation of PCs:
